Plant recordings in June 2019

by Rutger Barendse and Jeroen Willemsen

Tour de Belgique

After much contemplation and considering various options for our next BotanicalJourney, we had a brilliant idea – why not explore Rutgers' home country, Belgium, for the 2019 expedition? Belgium's unique geographical position, as described by Francois Crepin in his Manuel de la flore de Belgique in 1860, places it at the convergence of five major European vegetation zones. This promises a rich diversity of plant life, making it an exciting prospect for our botanical exploration.

Setting an ambitious goal for ourselves, we aimed to record at least 1000 different plant species in just over a week's time. To achieve this, we meticulously selected a wide range of ecosystems to explore. From the sandy areas in the northeast to the hilly landscapes in the southeast, the limestone regions in the south, the coastal dunes in the west, the river areas near the French border, and the former mining sites in the Ardennes, we planned to cover a vast array of habitats. Our hope was that these diverse environments would not only offer us an abundance of plant species but also provide us with enjoyable walks along the way.

Report of this BotanicalJourney

20 June 2019: Nature reserve "De Maten" near Genk  (Google map)

Our first walk was in a nature reserve quite close to Rutgers' home, where we set out to record both familiar and less common plant species. Among the less common ones, we encountered Potentilla norvegica and Vulpia bromoides. After that, we visited a nature reserve in the vicinity of the sewage water plant of the city of Genk. Here, we we recorded Filago minima, Myrica gale, Carex pilulifera and Berteroa incana.

A walking path took us to the direction of an observation point. We chose to leave the path and explore the swampy parts of the reserve right in front of the observation point. Here we recorded species like Eriophorum vaginatum, Drosera intermedia, Rhynchospora alba, Rhynchospora fusca, Narthecium ossifragum and Trichophorum cespitosum. Near the nature reserve there was a big canal. We ate an ice-cream and then continued our journey along the canal's edge. In the drier habitats, we recorded Sedum acre, Origanum vulgare and Sedum album. We found a way back to our car by walking through a recently reconstructed part of the reserve, where we found another new plant... Solanum lycopersicum ;-)

20 June 2019: Terril "Winterslag" near Genk (Google map)

In the vicinity of Genk and Maastricht, several artificial hills, known as "terrils," have been created from waste generated by former mining activities. These terrils have now been transformed into beautiful nature reserves, offering a wealth of interesting plant species. Our exploration of the Winterslag terril, located north of Genk, proved to be quite rewarding, with a variety of orchid species, including Ophrys apifera, gracing the slopes. The hill slopes were colored yellow with Spartium junceum, while Linum austriacum added to the colorful vegetation. An interesting finding as well was Plantago sempervirens. This plant has the size of a modest shrub, making it easily identifiable on the terril.

Salvia verticillataDuring our descent from the hill's summit, we encountered Salvia verticillata (see picture). Rutger thought he had found Inula salicina here before, but a closer look on the ray flowers showed that they were too wide for that species. So we decided that it had to be Buphthalmum salicifolium in stead. We also found this species in a new location nearby. In the wooded areas at the bottom of the terril, we had the pleasure of recording Platanthera chlorantha and Pyrola minor. As the first afternoon came to a close, we had already documented 402 plant species, marking a fantastic start to our Botanical Journey.

21 June 2019: Nature reserve near Gors-Opleeuw (Google map)

The conservator of a nature reserve managed by Natuurpunt, near the Flemish village of Gors-Opleeuw, kindly invited us to explore the area. With great enthusiasm, he guided us through the reserve, showcasing the plant life that was under his care. Among the notable discoveries was Dactylorhiza viridis, a unique orchid that cannot be found anywhere else in Flanders. The hay fields in the reserve also revealed other nice plant species, like Stachys officinalis, Ononis repens and Succisa pratensis. Among the numerous sedges, Carex pallescens and Carex otrubae stood out as particularly interesting finds. Our walk continued through a small poplar forest, where we encountered species like Circaea lutetiana, Verbascum thapsus and Rosa villosa. The plant life in this nature reserve was quite extraordinary and we were thankful for the invitation to visit the area.

21 June 2019: Le Thier à la Tombe (Google map)

Rhinanthus alectorolophus

The nature reserve "Le Thier à la Tombe", located near the village of Eben-Emaal, is characterized by its rich limestone terrain. Positioned on the western slope of Mont Saint Pieter, the reserve offers access from the main road, but we chose to walk around the perimeter at first, eventually climbing over a fence on the back side. Though small in size, "Le Thier à la Tombe" surprised us with its abundance of moist areas despite its elevated position on a hill. During our visit, we were able to record two species of Rhinanthus, namely Rhinanthus minor and Rhinanthus alectorolophus (see picture). Gymnadenia conopsea was present as well. As we moved to the drier sections of the reserve, we encountered Helianthemum nummularium, Genista tinctoria and Polygala vulgaris. Although our trip to the small reserve was relatively short, it provided us with several new plant species to add to our growing list.

21 June 2019: Montagne Saint Pierre (Google map)

Teucrium chamaedrys

The Montagne Saint Pierre is renowned for its abundance of orchids, and our visit to the area known as "Thier de Lanaye" proved to be fruitful. In a short amount of time, we were able to record Orchis militaris and Orchis anthropophora. A convenient path meandered across the hill slopes, allowing easy passage through the numerous gates. The limestone-rich habitat offered a variety of characteristic plant species, including Scabiosa columbaria, Teucrium chamaedrys (see picture) and Arenaria leptoclados. As we followed the zigzagging goat- and sheep-track, we came across Valerianella dentata, Marrubium vulgare and even Epipactis atrorubens.

After a while, we noticed a large rock higher up the hill. A steep and exhausting climb provided us with Clinopodium acinos. Descending, we reached a small nature reserve comprising three meadows, which turned out to be rich in orchids. Among them, we found Dactylorhiza fuchsii and Dactylorhiza praetermissa, displaying many intermediate forms often referred to as Dactylorhiza x grandis. Additionally, we recorded Platanthera chlorantha, and in a forested place near a fence, we found Pyrola rotundifolia.

Our journey back to the car involved climbing a steep hill that unfortunately was littered with waste, making the ascent somewhat uncomfortable. However, this challenging path led us to the discovery of a new plant species: Asplenium scolopendrium.

21 June 2019: River Meuse/Maas near Smeermaas (Google map)

The river Meuse's shore always proves to be a fascinating location for discovering new plant species. Seeds from upstream areas in France, Luxembourg and Belgium drift downstream and find fertile ground to germinate. A prime example of this is Sisymbrium austriacum, which originally hails from southern Europe but has successfully colonized the northern regions by following the course of the river Meuse. Nowadays, this species can be found at several locations in both Belgium and the Netherlands.

As we followed the shore of the river Grensmaas, we encountered a diverse array of plant species. Bolboschoenus laticarpus, Cyperus eragrostis and Potamogeton nodosus were among the interesting finds. Continuing our journey along a path to the north, we stumbled upon a sandy and stony area with many plant species, like Crepis foutida ssp. foetida, Mentha suaveolens and Rhinantus minor. Further downstream, we came across a pond in which we found Zannichellia palustris ssp. palustris and Spirodela polyrhiza. Our return journey yielded yet another discovery: Salvia pratensis.

22 June 2019: Hautes Fagnes (Google Map)

Phyteuma spicatum subsp. nigrum

On the next day of our journey we drove to an area renowned for its lush meadows, situated alongside the picturesque river Perlenbach and adjacent to a large military territory. Starting our adventure from a parking spot in Germany, near a convenient hostel just a stone's throw away from the border, we easily accessed the Belgian territory. The meadows alongside the small river were rich in species typical of swampy environments, like Crepis paludosa, Phyteuma spicatum subsp. nigrum (see picture) and Persicaria bistorta. Although Narcissus pseudonarcissus had already finished flowering, its distinctive appearance still allowed us to identify it. Another nice finding right next to the stream was Ranunculus penicillatus.

Vicia orobus

As we walked deeper into the valley, we explored the drier habitats, where Geranium sylvaticum, Polygonatum verticillatum, Melampyrum pratense and the spectacular Vicia orobus (see picture) greeted us. Our path led us to a sign prohibiting entry into the military area, but it didn't stop us from discovering fascinating plants nearby. We recorded Comarum palustre, Euphrasia stricta s.l. and Linum catharticum. Continuing our journey along a tarmac road cutting through the woods, we found the woods to be somewhat uneventful, with only a few new species to add to our list, including Genista anglica and Blechnum spicant. Nevertheless, the beauty of the meadows and the charm of the river Perlenbach contributed to a pleasant walk.

22 June 2019: Reinhardstein (Warche) near Ovifat  (Google map)

The castle Reinhardstein is a popular tourist attraction in the region called Warche. You can get guided tours through the castle and observe medieval knights hurrying through the woods. A rather peculiar sight when you are looking for wild plant species. Despite the medieval theater we focused on recording wild plant species in the area. As we walked from the car park to the castle, we were pleased to find Pulmonaria Montana, Alchemilla glabra and Valeriana dioica along the road. Nearby, in the ditch next to the path, we recorded Chrysosplenium oppositifolium and Alchemilla acutiloba. A nice surprise was the discovery of Ranunculus platanifolius.

The castle's rocky slopes rewarded us with sightings of Cystopteris fragilis, Knautia dipsacifolia, Sedum rupestre and Hieracium amplexicaule. We then followed a path going deeper into the woods, where we followed the nearly dry river Warche, hopping from rock to rock. There, we recorded Mimulus luteus and Chrysosplenium alternifolium. On our way back to the car, we encountered more plant species in the woods, including Mercurialis perennis, Phegopteris connectilis, Aconitum lycoctonum, Lysimachia nemorum and Gymnocarpium dryopteris. After a while we encountered two French women who sought directions to the castle. In hindsight, we are not certain whether we provided them with accurate guidance. If by chance they read this Botanical Journey report, we offer our sincere apologies for any confusion caused...

23 June 2019: Harbor in Antwerp (Google map)

The harbor in Antwerp may not seem like an obvious place to find interesting wild flower species, but it actually offers a rich hunting ground for plant enthusiasts. Particularly in areas where grain is delivered by ship, you can discover a diverse array of unique plant species scattered about. Exploring the harbor on a Sunday ensures a rather quiet experience without the hustle and bustle of large machines. We started our journey by visiting a former grain terminal near the Noordkasteel. Along the edges of a vast tarmac area, we found Lepidium bonariense, Rumex stenophyllus and Apera spica-venti. As we followed an old train track, our list of recorded species expanded to include Gnaphalium luteoalbum, Sisymbrium orientale, Bromus japonicas, Veronica peregrina, Hordeum jubatum and Tragopogon dubius.

Blackstonia perfoliata

Continuing our exploration, we headed to Romeynsweel, where a small nature reserve awaited us at the end of the road. Among the diverse plant species we encountered were Blackstonia perfoliata (see picture), Rhinanthus angustifolius, Epipactis palustris and Carex flacca. Regrettably, despite reports of its presence, we were unable to find the elusive Cephalantera longiflia at this location.

Our last harbor stop took us to an area near Muisbroeklaan, where a working grain terminal still operated. Amidst this industrial setting, we recorded species like Tordylium maximum, Bromus arvensis and Galium parisiense among other species. However, the most remarkable finding was Aphodelus tenuifolius, a Mediterranean plant not commonly expected to thrive in the colder climate of Antwerp.

23 June 2019: Kavel I straat, Knokke (Google map)

Cotula coronopifolia

As the day came to a close, we settled at a campsite in the Dutch village of Retranchement, which we had previously visited during our Botanical Journey to Zeeland in 2000. Initially, we had hoped to explore the nature reserve Het Zwin in the evening. However, we found that it was now enclosed by high fences as part of a Bird Park, which made access difficult. So, instead, we opted to visit a nearby swampy meadow. In this meadow, we came across a variety of interesting plant species, including Ononis repens subsp. Repens, Veronica catenata, Ranunculus baudotii, Limosella aquatica and Cotula coronopifolia (see picture). Alongside a deep canal we found funny species like Papaver somniferum, Phalaris canariensis and Torilis nodosa.

24 June 2019: Zwinduinen (Google map)
From the town of Knokke, the Zwinduinen (Dunes of the Zwin) are easily accessible. But do not think that you can enter the Zwin itself: it is surrounded by a large fence. Fortunately the dunes offer a chance to find interesting wild plant species as well. Near the entrance, in a moist area, we spotted Samolus valerandi, Lithospermum officinale, Carex viridula and Dactylorhiza incarnata.

Convolvulus soldanellaWe proceeded to follow a sandy path to the north from the first crossing, where we encountered an interesting mix of plant species, including Erodium cicutarium subsp. dunense, Bromus hordeaceus subsp. thominei and Phleum arenarium. Our journey extended eastwards, and near the border with the Netherlands, parts of the dunes were beautifully adorned with the pink flowers of Convolvulus soldanella (see picture). As we approached the shore, we found Honckenya peploides, before eventually heading back to the car via the beach.

While we didn't record any new plant species on the beach, our visit to the town of Knokke provided an opportunity to add a few additional maritime species to our list, including Euphorbia paralias, Eryngium maritimum and Cakile maritima.

24 June 2019: Kleiputten van Heist (Google map)

The clay pits near Heist form a nature reserve, but unfortunately, only a small part of it is accessible. In this area, you can still find small grassy fields with orchids and plant species typically associated with swampy environments. During our visit we recorded Dactylorhiza praetermissa here.

24 June 2019: Baai van Heist (Google map)

The Bay of Heist is a remarkable nature reserve, offering contrasting views of the bustling harbor of Heist/Zeebrugge on one side and the less scenic apartments of Knokke and Heist on the other. Situated amidst a landscape dominated by concrete, asphalt and busy people, the bay is the only piece of nature here. A narrow path runs through the reserve, allowing the visitor to observe the unique vegetation characteristic of salt marshes that are regularly flooded by the sea.

Euphorbia paraliasDuring our visit, we had the opportunity to record several typical plant species that thrive in this challenging environment. Among them were Atriplex portulacoides, Limonium vulgare, Suaeda maritima, Puccinellia maritima, Euphorbia paralias (see picture), Triglochin maritima and Juncus gerardii. To be honest, for some species it was necessary to cross the impressive fence on the west side of the bay. While crossing the fence might not have been entirely allowed, we noticed some gaps and missing sections that made it easy to pass.

24 June 2019: Westhoek, De Panne (Google map)

De Panne is a popular beach resort near the French border. A part from the usual sadness that somehow always seems to go with these coastal villages, there is a nice and large dune reserve called Westhoek. This reserve is rich in many rare plant species that can easily be spotted from the footpaths that crisscross the area. However, one downside was the presence of unsightly fences scattered throughout the reserve, which somewhat marred the natural beauty and made exploration challenging. Thankfully, numerous "elephant trails", presumably originating from groups who were permitted to enter the reserve, allowed us to enter the area as well.

We stayed as much on the paths as we could. At first, we passed several moist valleys, full with both Rhinanthus angustifolius and Rhinanthus minor. The various Dactylorhiza species were hard to identify, due to the frequent hybridization between Dactylorhiza praetermissa, Dactylorhiza fuchsii and Dactylorhiza incarnata. We also recorded Parnassia palustris, Euphrasia nemorosa, Anagallis tenella, Carex trinervis and Pyrola rotundifolia here.

Herminium monorchisAs we ventured further along the sandy paths, the dunes transitioned into drier terrains. There, we encountered Jasione montana, Viola curtisii, Lagurus ovatus and Viola hirta. Although the loose sands made walking a bit challenging, such open sandy dunes are essential components of northwest European dune reserves. Approaching the French border, we followed a path that lead towards the sea through swampy dune valleys. A nice surprise was Herminium monorchis (see picture), of which we estimated at least 300 specimens to be present (for as far as we could see from the path, of course). After this overwhelming sight, we followed the beach back to our car. Along the way, we spotted Beta vulgaris subsp. maritima.

24 June 2019: Camping Greenpark, De Panne (Google map)

We put up our tent in camping Greenpark in De Panne. We would not necessarily recommend this camp site to anyone who does not want to get drunk with his or her noisy friends, keeping the other guests awake during a large part of the night. However, we were on a mission here. Camp sites are highly underrated places for finding plant species. The presence of tourists from various parts of the world introduces different seeds that fall onto the ground while people are setting up and cleaning their tents. Some of these seeds manage to germinate and grow into new plants.

Paronychia argenteaCamping Greenpark is one of the places where these plant species manage to survive. Among them are a lot of clover species, which seem to thrive in the grassy and sandy habitats of the camp site. We recorded Trifolium glomeratum, Trifolium suffocatum, Trifolium micranthum, Trifolium scabrum and Trifolium resupinatum. Capsella rubella was nice as well. In the shrubby areas on the edge of the camp site, we found Carduus tenuiflorus. The friendly French and German owners of mobile homes were curious about our quest and kindly helped us locate Paronychia argentea (see picture). With such interesting finds on our list, we were able to sleep through the nighttime noise of the camp site's youthful guests and even resist the temptation to return the favor by making a ruckus right next to their tents at an early hour the next morning.

25 June 2019: Nature réserve "De Blankaart" south of Diksmuide (Google map)

The following day promised to be warm and hot, so we wasted no time and set out early to explore the nature reserve known as "De Blankaart." This beautiful reserve is located near a castle and features a diverse landscape of ponds, marshes, and meadows. The meadows in the region around the river IJzer are characterized by the occurrence of Oenanthe silaifolia and despite most of the fields being recently mowed, we were fortunate to discover several specimens of this intriguing species. The ponds in the reserve held their own surprises, and we recorded the presence of Butomus umbellatus, Lemna minuta, Nymphoides peltata and Thalictrum flavum.

Lathyrus palustrisOne of the highlights of our visit was the spectacular Lathyrus palustris (see picture) growing in the area. This plant species is rare in Belgium, and De Blankaart is currently the only known location for it. With the knowledge of roughly where to look and the meadows being mowed recently, reaching the spot with this remarkable find was relatively easy. In meadows with denser vegetation, we managed to record Oenanthe fistulosa and Alopecurus geniculatus.

25 June 2019: Honnelles (Google map)

Near the town of Honnelles there is a vast forested area on a soil rich in lime. The forest's undergrowth was lush and thriving, offering us the chance to record a variety of plant species. Among the plant species we encountered were Allium ursinum, Paris quadrifolia, Hyacinthoides non-scripta and Tamus communis. In more moist habitats we found Cirsium oleraceum as well. Despite the high temperatures, we were determined to explore further and decided to climb a small hill covered with forest. As we walked towards the back of an old quarry, we were rewarded with the sight of Orchis purpurea.

25 June 2019: Lime stone meadows near Nismes (Google map)

Ophrys fuciflora

In the past we have visited one of the lime stone meadows near Nismes. This time, we decided to check out two other meadows. One of them was a random guess (we noticed interesting vegetation while driving on the main road) and the other one was a known location for some orchid species. On both of the locations we recorded Vincetoxicum hirundinaria, Digitalis lutea, Teucrium chamaedrys, Geranium sanguineum and Teucrium botrys. On the first field we also found Thymus praecox, Calamintha nepeta, Ophrys fuciflora (see picture) and Orchis anthropophora. On the second field we found many other orchid species, like Epipactis atrorubens, Dactylorhiza viridis and Platanthera bifolia. We recorded these species by randomly zigzagging over the hill top. Unfortunately Neotinea ustulata was no longer in bloom, but the presence of Asperula cynanchica throughout the meadow added to the charm of the area.

25 June 2019: Camp site Du Moulin in Romedenne  (Google map)

As the scorching heat of the afternoon pushed the temperature beyond 30 degrees Celsius, we decided to conclude our botanical quest for the day and search for a campsite to rest. Our first attempt led us to a deserted site, except for two barking dogs. Hoping they were cared for, we moved on to a second option, which turned out to be nothing more than a simple field with a toilet and a shower. But hey; who needs more than that? So we installed our tents and made ourselves something to eat. Rutger checked the area briefly for camp site adventives and found Potentilla argentea, Vulpia bromoides, Trifolium striatum and Draba muralis. With almost 900 different plant species already on our list, we were well on our way to reaching our ambitious goal of 1000 species.

26 June 2019: Lime stone hill near Treignes (Google map)

As you probably know from previous Botanical Journeys, we are very fond of lime stone hills. Especially when wild plants are given space to grow and a natural succession takes place. The hills have a high rate of biodiversity, as the environment of the village of Treignes clearly shows. Parking our car at the town square, we set off on foot along a dead-end road that led to a narrow path winding up the hillside. 

Fumana procumbensOne of the highlights of the area was the presence of Limodorum abortivum, a sought-after orchid species that had been previously observed by many other botanists, as was evident from the numerous traces they had left behind. Carex digitata was present in the grasslands. On rocky places we found species like Sedum rupestre and Fumana procumbens (see picture). The abundance of the latter was a pleasant surprise, given its rarity in Belgium. Himantoglossum hircinum was scattered throughout the area and so were Teucrium botrys and Gymnadenia conopsea. Among the sun-drenched hills, the striking heads of Allium sphaerocephalon stood out prominently. We were very satisfied with the valuable and diverse plant life in this location.

26 June 2019: Grassland near Mazee (Google map)

As we continued our Botanical Journey towards Dinant, we came across another delightful reserve featuring a variety of limestone plant species. This small field near Mazee was a treasure trove of orchids, although most of them had already finished flowering. Among those we could still identify were Ophrys apifera, Gymnadenia conopsea, Ophrys insectifera, Orchis mascula and Platanthera chlorantha. Large parts of the field were a bit overgrown with brambles and grasses, but we managed to find Prunella laciniata on this site, as well as the intermediate Prunella x intermedia (P. laciniata x vulgaris).

26 June 2019: Lime stone hill near Vaucelles (Google map)

Teucrium montanum Next, we decided to pay a visit to the town of Vaucelles. We climbed up a hill next to a rocky outcrop somewhere outside the village. On the bottom of an old quarry we recorded Hypericum pulchrum and on the rocks we found Melica ciliata and an array of ferns, including Asplenium ruta-muraria, Asplenium trichomanes and Asplenium ceterach. Though the path upwards required some perseverance, the presence of numerous specimens of Teucrium montanum (see picture) made the journey quite enjoyable. Among our discoveries on the ascent were Seseli libanotis and Rumex scutatus. Ophrys apifera, a captivating orchid, was present as well. We got used to the presence of Allium sphaerocephalon, which was abundantly present again.

26 June 2019: Along the river Meuse near Waulsort (Google map)

As we continued our botanical adventure, we spotted a delightful surprise from our car - a small Iris species atop the walls surrounding Waulsort castle. situated on the shore of the river Meuse. Upon closer inspection, we identified them as Iris pumila. We followed the shore of the river for a short distance and recorded Scutellaria galericulata, Petrorhagia prolifera and Cerastium tomentosum.

26 June 2019: Réserve naturelle domaniale de Champalle near Yvoir (Google map)

We were desperately in need of new species and we knew that there were still some lime stone plants missing on our list. Therefore we went to a nature reserve near Yvoir. This turned out to be a wise decision. Next to the many species that we had recorded on one of our previous sites (including again the very very very abundant Allium sphaerocephalon) we found species like Phleum phleoides and Dianthus carthusianorum at Yvoir. As we followed the path through the open rocky slope, we recorded Lactuca perennis, Helianthemum apenninum and Arabidopsis arenosa as well. We also recognized Aster linosyris, although it was too early to witness its flowers in full bloom. It was recognizable nevertheless. As we made our way back to the village, we recorded Festuca pallens and Ranunculus auricomus in the forest.

26 June 2019: La Houille near Bourseigne-Neuve (Google map)

Hieracium peleterianum A few years ago, Rutger paid a visit to the surroundings of the small river La Houille, near the French border. He recalled some remarkable species from his previous visit, so we decided to revisit the area. The road sides were colored blue with the many Centaurea montana. After a long walk along the road, we found what we were looking for: Hieracium peleterianum (see picture). This location near La Houille is the only known place where this plant species can be found in Belgium. Growing on a steep, forested slope, accessing them was challenging, but we were able to observe these unique plants from the road. On the other side of the road, on a low wall, we also recorded Euphrasia micrantha, which Rutger had observed during his previous visit as well. Other plant species near La Houille included Pulmonaria mollis, Circaea x intermedia (C. alpina x lutetiana), Anthericum liliago and Galium mollugo subsp. mollugo.

27 June 2019: Réserve naturelle de Raymond Mayne near Torgny (Google map)

In the past, we both have visited the region The Gaume several times. The Gaume, the most southern part of Belgium that is rich in lime, gives rise to a unique and diverse flora and fauna. Our Botanical Journey led us to a nature reserve situated just uphill from the most southern village of Belgium, Torgny. A small part of the reserve can be overlooked from a path that runs through it. The many orchids and other interesting plant species make it hard to stay on the path. That is probably why we saw many small tracks running through the reserve. However, we found that most of the plant species could be observed from the designated path, making it unnecessary to venture off the route.

Melampyrum arvenseUpon entering the reserve from the direction of a small church with a pick-nick area, we were immediately captivated by the abundance of Gymnadenia conopsea. These graceful orchid grew alongside Anacamptis pyramidalis, which displayed a darker and richer purple hue. We also spotted Epipactis atrorubens and Orchis anthropophora. Alongside these captivating orchids, numerous non-orchid species were thriving as well. One of the most striking was Melampyrum arvense (see picture), but we also recorded Astragalus glycyphyllos and Dianthus armeria.

After traversing the reserve, we entered a forest with a lush undergrowth. This tranquil woodland provided a habitat for species like Paris quadrifolia, Stachys alpina and Euphorbia stricta. As a challenge to ourselves, we decided to identify a bramble. It was a nice looking specimen with needle-sharp spikes and pointed leaves. We used the website (of which we have an off-line version graciously provided by our friend Thomas) to successfully identify the specimen as Rubus pedemontanus. We also recorded Pulmonaria obscura and Platanthera chlorantha in this nice forest.

Pulsatilla vulgaris As we returned to the nature reserve, we had a brief encounter with the maintenance crew: a hurdle of noisy and nosy goats. Adjacent to the original reserve, we found a newly restored patch of land for wild plants, supported by the European Union (see Although the field was still in the early stage of restoration, we observed several interesting plant species, including Rhinanthus minor, Onobrychis viciifolia, Gymnadenia conopsea, Anthyllis vulneraria and Melampyrum arvense. One particularly surprising find was a Pulsatilla vulgaris displaying a lovely flower (see picture), even though it was already the end of June! With this rewarding discovery, we concluded our visit to the enchanting reserve.

27 June 2019: Réserve naturelle domaniale du Cron de Montauban near Buzenol (Google map)

Another site that we knew from the past was Buzenol, where we conducted a preliminary survey of plants and insects in 1997. The promising results from our previous visit motivated us to return and explore the area once again. This time, we followed a path with many walking-route signs, albeit next to a sign with "acces interdite". Undeterred, we ventured forth to discover the treasures of Buzenol. The path initially led us through a lush forest, where we encountered species like Cystopteris fragilis, Galium sylvaticum and the delicate orchid Neottia nidus-avis. As we continued our journey, we noticed water trickling from the hillside at various points, creating moist environments that supported a diverse vegetation. This habitat proved to be a haven for several Carex species, including Carex lepidocarpa, Carex rostrata and Carex paniculata. And amidst these fine species we were astonished to stumble upon an exceptionally rare plant as well: Rubus saxatilis !!!

27 June 2019: Swamp in the Réserve naturelle le marais de Chantemelle (Google map)

In our quest to reach our goal of 1000 different plant species, we set our sights on exploring a swampy area near Chantemelle that we had spotted on Google Satellite images. As we arrived, we noticed a recent excavation site next to the road, adorned with species like Dianthus deltoides. However, what truly surprised us was the discovery of Helichrysum arenarium: an exceedingly rare plant in Belgium. We had heard of experiments involving the re-introduction of this species, and it appeared that we had stumbled upon one of these sites. Helichrysum arenarium had managed to spread across about a quarter of the area.

Eager to explore further, we ventured into the boggy and swampy parts of the reserve. Here, we recorded species like Menyanthes trifoliata, Potentilla palustris and Eriophorum angustifolium. Dactylorhiza maculata and Dactylorhiza fuchsii were present as well. As we reached the far end of the reserve, several splendid specimens of Platanthera chlorantha caught our eye. On our way back to the car we also found Saxifraga granulata, Anacamptis pyramidalis and Stellaria nemorum in the surrounding forest. A quick survey of an arable field produced less weeds than we had expected. We recorded Orobanche purpurea and Phacelia tanacetifolia nevertheless.

27 June 2019: Old railway tracks south of Heinsch  (Google map)

Years had passed since our last brief visit to the stretch of old railway tracks near Heinsch, and as we returned, we noticed significant changes. A part of the area had been transformed into a solar energy field, but fortunately, the majority of the terrain remained unchanged, with the familiar old railway tracks still intact. The harsh environment, with minimal water and extremely high temperatures, creates a unique habitat for special plant species.

Linaria repensRight at the start of our visit we found Linaria supina and Linaria repens (see picture). As we continued our exploration, we also came across other interesting species such as Herniaria glabra and Minuartia hybrida. We traversed the area from one side to the other and returned along the wooded north side, where a wall stood tall. Here, we encountered Alyssum alyssoides and Valerianella dentata. Somewhere in the middle of this extraordinary area, we made a special discovery, namely the 1000th plant species of this Botanical Journey! It was Chondrilla juncea. This milestone filled us with joy and a sense of accomplishment, knowing that we had reached our ambitious goal with still one promising day ahead of us!

28 June 2019: Slate slopes near Vielsalm (Google map)

On the final day of the Botanical Journey, we decided to revisit the type of terrains that marked the beginning of our trip: fallow fields and remnants of mining activities. Our destination was the town of Vielsalm, where a slate production site once thrived. Nowadays, the piles of slate residue form loose hills that make the search for plants quite challenging. However, we were determined to find some botanical specialties in this unique environment.

Cryptogramma crispaAs we started our walk, the first interesting find was a Bergenia. This plant, originally a garden escapee, had successfully established itself on the edge of the site. After careful examination, we identified it as Bergenia crassifolia, a species not previously reported in Belgium. We collected a small sample of the plant for further analysis and documentation. We followed several of the many elephant trails through the wooded area and recorded Euphrasia stricta s.s. and Euphrasia officinalis. Climbing a loose pile of slate, we were excited to record the presence of Cryptogramma crispa (see picture). This plant was already known to occur in the surroundings, but we managed to find some new locations as well. In a cold and damp remnant of former industrial activities, we recorded Cystopteris fragilis.   

28 June 2019: Rocky outcrop near Aywaille (Google map)

Then we headed to the town of Aywaille where we had once been before, after we had lost our exhaustion pipe on the highway. Here too many remnants of former mining activities lay scattered through the landscape. From a large distance one can notice the impressive rocky outcrops above the town. Part of the area is referred to as Réserve naturelle de la Heid des Gattes.

Sempervivum funckiiFirst we followed the river Amblève. The road was formally closed, but a well maintained hole in the fence suggested that many people still walked this path regularly. Underneath the shade of the trees, we came across Sedum telephium, Melica ciliata and Cardamine impatiens. Continuing along the path, it was not difficult to notice Sempervivum funckii (see picture) on an exposed rocky slope. Some botanists claim that this plant is endemic to Belgium, though this assertion is not without debate. Despite the challenge to reach the plants, we managed to take some wonderful pictures and, well, let's just say the way down was quicker than the way up! Further east, we encountered a wall adorned with numerous specimens of Asplenium trichomanes. We recorded Artemisia campestris, Vincetoxicum hirundinaria and Rumex scutatus here as well.

Sempervivum funckii Following a steep footpath up the hill, we came across Polystichum aculeatum. Along the way, we stumbled upon a visitors' center dedicated to the former mines and the present nature, offering a pleasant and informative stop. On the grassy fields adjacent to the center, we spotted Gymnadenia conopsea, Aster linosyris and Centaurium pulchellum. We concluded this years' Botanical Journey on the very end of the path by recording Asplenium adiantum-nigrum and Asplenium septentrionale, which made for a beautiful finale to our list.

In total, we managed to record 1,031 different plant species in Belgium, successfully achieving our goal!

List of the recorded plant species

Only the first finding of each species is mentioned. This means that species recorded on multiple dates, such as both on the 26th and the 27th of June, are only noted on the 26th.
