Gargano (Italy)

Plant recordings in April 2018

by Rutger Barendse and Jeroen Willemsen 

Parco nazionale del Gargano


The Gargano is a well known place to look for wild orchids and other rare plants. For that reason, the area had been on our list for a very long time. In 2018 we were finally able to go to Italy and visit the Gargano. We took a plane to Bari, hired a car with an unwanted but comprehensive all-risk insurance and headed northwards. Our destination was a campsite located south of Manfredonia. However, upon arriving at the late hour of 2 o'clock in the night, we found the campsite in deep sleep, leaving us no choice but to spend the night in our car instead of a "mobilhome". As you can imagine, we didn't get much sleep that night...

The Gargano is part of the Italian Puglia region. When you look at a map of Italy, you will notice the peninsula of the Gargano straight away: it is sticking out of the heel of the country for about 70 kilometers into the Adriatic Sea. The area is characterized by its mountainous terrain, with peaks reaching over 1000 meters above sea level. Within the Parco Nazionale del Gargano one can discover diverse landscapes, including lush forests, rocky slopes, grassy meadows and abandoned olive groves. The area south of the Gargano, where our campsite was situated, has a rich variety of salt marshes and coastal plains. The view of the Gargano peninsula from the sandy beaches is absolutely breathtaking.

Report of this BotanicalJourney


23 April 2018: Around campsite Lido Salpi (Manfredonia) (Google map)

Papaver rhoeas

So that first night in Italy was far from restful, as our car provided a cold and uncomfortable sleeping spot. However, the silver lining was that we woke up early, allowing us to start our plant-listing adventure promptly. We began by examining a barren field near the main road to Manfredonia, just outside the still-closed gate of the campsite. This area mainly had common plant species. Papaver rhoeas (see picture) was abundant in the field. Impressive was the large amount of Ferula communis, which grew everywhere and had caught our attention even in the darkness of the night before.

Dunes After checking in at the campsite, we headed to the nearby beach at Lido Salpi. The coastal region featured small dunes where we spotted various typical species, such as Hordeum marinum, Erodium cicutarium subsp. dunense, Artemisia campestris subsp. maritima, Cakile maritima and Medicago marina. On the beach itself we noted the presence of Ononis variegata (see picture). Moving northward, in the direction of Manfredonia, we encountered fallow fields with low and dry vegetation a little more away from the sea. We recorded Dittrichia viscosa, Alkanna tinctoria, Pancratium maritimum, Salsola kali and Scolymus hispanicus here.

Ononis variegata At the remains of an old camp site or something, we followed a tarmac road away from the coast. In its surroundings we recorded species like Urospermum dalechampii, Convolvulus elegantissimus, Dipsacus ferox and Bartsia trixago. An interesting finding was Serapias cordigera, of which we found only two specimens here. A little further we had to cross a narrow bridge by foot. That was quite an adventurous experience in the busy Italian traffic: people were supposed to drive at a speed of only 50 km per hour, but the slowest car went about 90. So we turned back quickly and returned to Lido Salpi via the beach.
   

23 April 2018: Alongside the road from Manfredonia to Tomaiolo (SP57)  (Google map)

In the afternoon we drove up a road north of Manfredonia, with numerous curves. When we noticed a large quantity of Anacamptis pyramidalis, we parked our car and walked into the grassy field. Climbing the hill randomly, we hoped to stumble upon more intriguing plant species. We recorded Stachys germanica, Centaurea solstitialis, Pallenis spinosa and Bituminaria bituminosa on this hill. Other decorative species were Tragopogon dubius and Nigella gallica.

Onobrychis aequidentataIn addition, we found a Serapias species as well, which we identified as Serapias bergonii. Near the road were several spots with Ononosma echioides, which is a truly delightful plant indeed. The fruits of Onobrychis aequidentata were very characteristic and above all funny to see (see picture). At one point, we found ourselves near a shallow ravine, where the sounds of young peregrine falcons filled the air. From that point, we made our way back to the road and returned to our car. At the end of our first day in Italy, we had recorded a total of 245 plant species – a fantastic start to our Botanical Journey!
   

24 April 2018: Sentiero Pellegrini near Monte Sant'Angelo (Google map)

Ophrys tenthredinifera

The next day we made our way to Monte Sant'Angelo, where we discovered the "Sentiero Pelegrini" footpath just outside the town. As we followed the path down the hill, we were immediately greeted by a field filled with numerous orchids, including Ophrys sphegodes and Anacamptis morio. There were some nice specimens of Ophrys tenthredinifera as well (see picture). Passing through a gate, the road led us through rugged grassy areas, where we recorded many nice species like Cerastium brachypetalum, Silene italica, Campanula garganica, Asperula cynanchica and Smyrnium perfoliatum.

By pure coincidence we stumbled upon numerous specimens of Viola graeca, which, according to Sandro Pignatti, is only recorded in Italy in the area around Monte Sant'Angelo. The color variation of these plants was remarkable, ranging from deep purple to pale yellow and almost white. Further down the hill we left the footpath as we spotted an abundance of orchids. Among them were Anacamptis papilionacea, Orchis anthropophora and Orchis quadripunctata. From that point we returned to Monte Sant'Angelo. We did not follow the path, but crossed the hill randomly. This spontaneity rewarded us with the discovery of several new plant species. In the town where we had parked our car, we found a large quantity of Lamium garganicum.
   

24 April 2018: Along the roads SS272 and SP52b from Monte Sant'Angelo to Virco del Gargano (Google map)

We parked our car at various parking areas along the SS272 and the SP52b. Our last stop, near the SP52b, turned out to be particularly interesting. It caught our attention as we noticed an abundance of Orchis italica in the area. Excited by the beautiful sight, we decided to venture into the forest, which predominantly consisted of Quercus pubescens and Quercus ilex, along with other species. In the shaded parts of the forest we came across typical plant species like Lamium bifidum, Arum italicum, Neottia nidus-avis, Lamium maculatum, Fragaria moschata, Platanthera chlorantha and Brachypodium sylvaticum. It did not take us long to find Limodorum abortivum too. This species is well known from cork oak forests.

Iris revolutaAs we explored the more open areas of the woods, we encountered Tordylium maximum, Cistus monspeliensis, Valeriana tuberosa, Polygala nicaeensis and Dactylorhiza romana. In addition, we stumbled upon several grassy fields within the forest. Though cows had clearly grazed the vegetation, there were no recent signs of cow activity. Surprisingly, these fields were abundant with wild plant species, including Ornithopus compressus, Calepina irregularis, Helianthemum apenninum and a Polygala species that we have not been able to identify yet. One remarkable discovery was Iris revoluta (see picture), which was present with both white and purple flowers. The extensively grazed fields turned out to be rich in wild plant species! On our way back to the car we also recorded Ophrys bertolonii near the dirt road.
  

25 April 2018: Oak forests near Santuario di San Matteo Apostolo (Google map)

Helianthemum apenninum

Today our plan was to explore the deciduous forests of the Gargano. Contrary to the rocky impression you get from Manfredonia, the area around San Marco in Lamis boasts well-developed forests, mainly consisting of mature oak trees. We parked our car below the Santuario di San Matteo Apostolo and began our ascent up the hill, crossing several tarmac roads. Narcissus poeticus was abundant in the woods, but unfortunately there were only few specimens with intact flowers. Allium triquetum was the second plant that colored the forest almost completely white. Among the stones and old tree trunks we discovered Helianthemum apenninum (see picture), along with Asplenium trichomanes and Asplenium ceterach. Surprisingly we also found Viola graeca, a species that according to Pignatti should be restricted to the area around Monte Sant'Angelo.

Cyclamen hederifolium

Our woodland adventure led us to encounter a variety of plant species, including Corydalis cava, Thlaspi montanum, Crocus tommasinianus, Sedum cepaea and Cyclamen repandum (see picture). Orchids were abundant as well, and we were delighted to find Ophrys argolica, Ophrys holoserica, Dactylorhiza sambucina, Orchis provincialis and Cephalanthera longifolia.

Then we followed a narrow path near the Sanctuary, where signs warned us that we entered holy grounds and therefore were not allowed to consume pasta. The forest became denser in this area, and we recorded Selaginella selaginoides here. Near the sanctuary we encountered some stray dogs. A tourist was foolish enough to try to pet one of the dogs. He is lucky that he still has both of his hands. It was a close call.
   

25 April 2018: Several stops alongside the SP22 and the SP43 south of Cagnano Varano (Google map)

Serapias cordigera

We made several stops along the SP22, particularly when we spotted striking plant species (often orchids or daffodils). One remarkable location was a former Lupine field where we observed some interesting weed species, including Mentha longifolia, Veronica hederifolia subsp. hederifolia, Agrostemma githago, Lithospermum arvense, Asperula arvensis and Ranunculus arvensis. Additionally, we found Paeonia mascula in the forest.

Heading south of Cagnano Varano, we visited an olive yard. Olive trees are known to live for many years, and in the undergrowth of derelict olive yards you can find all kinds of plant species. We recorded Cynoglossum creticum, Cnicus benedictus, Lathyrus clymenum and Serapias cordigera (see picture) here.
   

25 April 2018: Shore of Lago di Varano (Google map)

On the north side of the Gargano lies a vast saltwater lake called Lago di Varano. Intrigued by the area, we followed a narrow tarmac road that led us to the lake shore, where a small freshwater stream flowed into the salty lake. he environment around this junction of waters offered a unique habitat, showcasing species that thrive in humid conditions, including Typha latifolia, Apium nodiflorum, Veronica anagallis-aquatica and Conium maculatum. The surroundings of the not well-maintained cottages on the shore provided us with Matricaria chamomilla and Brassica nigra. Moreover, the presence of Spergularia salina and Suaeda maritima served as clear indications of the influence of salt water in this vicinity.
   

26 April 2018: Litoranea Varcaro (Google map)

We were desperately looking for fresh water. Not for ourselves, but for finding fresh water plants. So we used Google Maps to locate small streams and ravines that might harbor such species. Our search led us to Litoranea Varcaro, located south of Mattinata. Unfortunately, luck was not on our side this time. Not only did we fail to find any fresh water, but the small ravine we had hoped to explore turned out to be inaccessible due to its steep borders and dense, thorny vegetation. However, the adjacent olive tree yards proved to be easily accessible, and there we made some interesting botanical discoveries. Among the plants we recorded were Trifolium glomeratum, Medicago polymorpha and Hippocrepis multisiliquosa — three clover species that provided a good food source for Orobanche minor, of which we found some rather big specimens. While these findings might not have been as visually striking as some others, they were still valuable contributions to our growing plant list.
   

26 April 2018: Coastal road SP53 towards Vieste (Google map)

Serapias politisii

We also wanted to record species of the maquis vegetation, a dry and dense landscape of low shrubs and plants. We followed a footpath down hill at first, but soon we noticed Serapias politisii (see picture) and Serapias neglecta ssp. apulica on the hill slopes surrounding us. So we ended up walking randomly through the maquis to find more plant species. This worked out very well: we recorded Himantoglossum robertianum, Biscutella didyma, Anthyllis montana, Cistus creticus and Coronilla juncea. Although the Ophrys species we encountered had no fresh flowers, making identification impossible, we were fortunate to find Gladiolus italicus widely distributed throughout the area. Additionally, besides the previously mentioned Serapias species, we also recorded Serapias bergonii and Serpias cordigera.

26 April 2018: Riserva Statale Monte Barone (Google map)

There are a few things about Italians that we do not fully comprehend. One is the dangerous way they drive, the second is the enormous amount of garbage that they throw out of their cars everywhere, and the third is the tendency to fence off beaches, restricting any public access and making it challenging for anyone to reach the shoreline. So when we followed a narrow road down to the shore in the Riserva Statale Monte Barone, expecting to reach the sea, we were surprised by the inaccessibility of the coast thanks to some hotels. We walked around for a bit and recorded Klasea flavescens, Scandix australis and Echium sabulicola. But because the path ended at a fence every time we tried to follow a new track, we left the area with disappointment. Though we could add some species to our list, we would not advise anyone to go there. Unless you like fancy hotels with fences and private swimming pools at the beach. We prefer swimming in the sea at publicly accessible places.

26 April 2018: Sentiero natura Mergoli-Vignanotica (Google map)

Our next destination turned out to be quite rewarding. We followed a nature trail that led us through various unique habitats. The trail began in an environment resembling maquis, where we spotted Clypeola jonthlaspi, Ononis ornithopodioides, Nigella arvensis and Dorycnium hirsutum. As we continued along the path we entered a dry and exposed pine forest that was abundant with Cistus creticus. Additionally, we recorded Dorycnium hirsutum, Melilotus sulcatus, Leontodon hyoseroides and Vicia tetrasperma subsp. gracilis.

Urtica piluliferaIn an open clearing within the woods we found a single specimen of Anacamptis coriophora subsp. fragrans. As we progressed, the forest gradually transitioned into a deciduous forest with a milder climate. It was initially challenging for us to identify Ononis viscosa, but with the aid of some digital resources, we managed to do so later on. The nature trail finally led us to a parking area near a public beach, where we came across Urtica pilulifera (see picture).

Then we made our way back to our car. To our dismay there was quite a bit of broken car glass scattered around, indicating that some unfortunate car burglaries had taken place. Thankfully, our Ford Fiesta seemed to hold no appeal to the burglars, as there was nothing valuable inside, except for a slice of bread and a jar of marmalade, along with Rutgers' rather odorous shoes.
   

26 April 2018: Torre dell'Aglio (Google map)

Allysoides sinuata

Despite (again) the presence of broken car glass and signs of frequent human sanitary usage of the area, we managed to make a remarkable discovery at the Torre dell'Aglio: Allysoides sinuata (see picture). According to Pignatti, this plant's occurrence in Italy is restricted to the region of Puglia, making our finding all the more significant. We were delighted with this rare plant sighting. Additionally, it was a pleasure to come across the lovely flowers of Nigella arvensis during our walk.

26 April 2018: Beach next to the SP53 (Google map)

Silene colorata

Late in the day we made our way to a beach near the SP53. To our delight, the beach seemed to have been less frequented lately, allowing for an interesting vegetation to grow on the partially overgrown sand. We spotted Silene colorata (see picture) and Medicago littoralis. Additionally, Xanthium orientale, Convolvulus soldanella and Sagina maritima also caught our attention on this beach. Some parts of the beach were marked by small streams of fresh water flowing into the sea, where we recorded Juncus ambiguus, Equisetum ramosissimum and Cyperus laevigatus. As we explored the area, a stray dog approached us, seeking companionship. Although the dog seemed happy to see us, we were more focused on our quest to find wild plants, so we left the dog behind to it's disappointment.
 

27 April 2018: Salt lakes at Lido di Rivoli (Google map)

Papaver rhoeas

To find plant species of totally different habitats (salty in this case), we ventured towards the (former) salt lakes at Lido di Rivoli, situated south of Manfredonia. Our journey led us along a road that had been closed for cars, but it remained accessible on foot. At the end of the road we walked across the beach, behind a small embankment that separated the beach from the salt lake. We encountered numerous bird species, although we shall not delve into their details in this BotanicalJourney. However, we did come across some plant species that were new additions to our list and were typical of salty environments. Notable finds included Salsola vermiculata, Juncus inflexus, Polygonum maritimum, Matthiola tricuspidata, Limonium vulgare and Puccinellia convoluta. Amidst this coastal landscape, the vibrant red hues of Papaver rhoeas created a striking contrast with the serene blue waters of the salt lakes (see picture).
   

27 April 2018: Salina di Margherita di Savoia (Google map)

The Salina di Margherita di Savoia is a vast complex of both active and abandoned salt lakes, which has been designated as a Nature Reserve. While this area is primarily known for attracting bird watchers, we also came across some interesting plant species during our visit. Along a small fisherman's path leading to the sea, we spotted Cyperus esculentus, Arenaria leptoclados and Galium spurium. Near a pile of waste in an alley of Ferula Communis (the SP66), we crossed a ditch to get into a wet land (probably a former lake). We recorded Lemna minor, Oenanthe lachenalii, Alopecurus myosuroides, Ranunculus baudotii and Medicago murex there.

27 April 2018: Fallow fields near Manfredonia (Google map)

Anacamptis coriophora ssp fragrans

We attempted to access some fallow fields near Manfredonia, but were sent away by the Guardia di Finanza at the harbor ("no photo near the sheeeeep!"). However, we found a suitable alternative near a school, which turned out to be a vast area of fallow fields, containing many spectacular plant species. Hundreds (maybe thousands) of specimens of Serapias orchids were present. We believe they were Serapias parviflora and Serapias orientalis. Noteworthy was a completely white specimen of Serapias orientalis, which we have posted on our page of anomalies. Hypochromy, a color variation, is apparently not uncommon in S. orientalis, as mentioned by Pierre Delforge. Another exciting find was Anacamptis coriophora ssp fragrans, of which we encountered nearly a hundred specimens (see picture). Bellardia trixago (Bartsia trixago) was also abundant in the area. Additionally, we spotted other delightful plant species such as Carduus defloratus, Ophrys sphegodes subsp. atrata, Trifolium resupinatum, Pallenis spinosa and Amaranthus hybridus.
 

28 April 2018: Alongside the SP57 north of Manfredonia (Google map)

Stachys spec

We explored the SP57 road, which wound tightly along the slopes of a rocky mountain. Around km 6, we parked our car and ventured into the hill meadows. The panoramic view of the Manfredonian coast was breathtaking, and we were delighted to come across numerous flowers of Nigella arvensis. Serapias species were abundant as well, although some of them had already dried out. The tiny yellow flowers of Ajuga chamaepitys seemed to be everywhere. Amidst the meadows, we discovered Ornitogalum comosum and many plants of Onobrychis alba. Additionally, we stumbled upon a cushion of leaves on the rocks, the identity of which we couldn't immediately determine. We made sure to take photos for later analysis. Similarly, we struggled to accurately identify a Stachys species (see picture), and we plan to consult our photographs for further examination (without result up to the present day).

28 April 2018: Near Ruggiano (Google map)

We took a road near the village of Ruggiano, but it quickly became too narrow for our car. Fortunately, we had been obliged to buy an insurance we didn't want, so now we didn't need to be bothered by minor scratches on our vehicle. According to the Ryanair website our car should have been "a Volkswagen Polo or similar", but it turned out to be a Ford Fiesta. That comparison is like saying Ophrys lutea is similar to Helianthemum nummularium. Speaking of which, Ophrys lutea was by far the most common orchid in the area around Ruggiano.

Neotinea ustulataWe followed the narrow path all the way north and recorded various plant species, including Sideritis italica, Erysimum rhaeticum and Euphrasia stricta s.l.. We also spotted some specimens of Ophrys bertolotii, Orchis tridentata and Ophrys tenthredinifera. Along the way we came across several old arable fields, where we discovered Legousia hybrida, Camelina microcarpa and Bifora radians. As we continued northward we noticed a small depression in the landscape, which turned out to be a somewhat moist habitat. There, we found Neotinea ustulata (see picture) and Ajuga genevensis. Under the oak trees we came across Doronicum, but a small detour through a pine forest didn't yield any new plant species. Nevertheless, this was a worthwile walk!
   

28 April 2018: Alongside the SP52b (Google map)

We noticed grassy fields when we were looking through the woods near the SP52b, north of Monte Sant'Angelo. The meadows proved to be very rich in plant species, and we spotted the beautiful blue and white flowers of Salvia clandestina throughout. The occurrence of Serapias species is almost not worth mentioning anymore, but Euphorbia barrelieri was new for us. Other new species to our list were Globularia nudicaulis, Salvia verbenaca and Herniaria glabra. In the forest we recorded Limodorum abortivum as well.

28 April 2018: Arable field near the SP50bis (Google map)

Due to a navigation error, we ended up stopping at the SP50bis. We had originally intended to follow a narrow road through the higher parts of the Gargano, where we had been a couple of days ago, but we couldn't recall which road it was. However, this unplanned stop turned out to be a fruitful one as we recorded some new plant species that are commonly found in arable fields. Among them were Viola tricolor, Veronica agrestis, Allium nigrum and Vicia hybrida.
 

28 April 2018: Hornbeam forest southwest of Carpino (Google map)

Due to the aforementioned navigation error, we were not expecting to come across a Hornbeam forest with impressive old trees. Therefore, the forest southwest of Carpino turned out to be a delightful surprise. Its lush undergrowth was extremely rich in plant species. The recent rain had filled the air with pleasant scents, making our walk through the woods a delightful experience. We recorded plant species such as Sanicula europaea, Thalictrum aquilegiifolium, Polygonatum multiflorum, Euphorbia amygdaloides and Rosa arvensis. After that, we returned to the camp site. The atmosphere there was quite lively with noisy Italians engrossed in watching football. Their cheers and shouts filled the air, almost driving the other campsite guests to the brink of madness. Despite the commotion, we surprisingly had no trouble falling asleep that night...

29 April 2018: Strada communale Paratino (Google map)

Sideritis italica

A few days ago, we explored a road that led through promising orchid pastures. However, due to the late hour, we didn't pay much attention to the surrounding plant species at that time. Later, when we tried to recall where we had been, we struggled to remember the exact location. After some deep thought, we finally recollected that the road was somewhere northwest of Mattinata. It turned out to be the Strada comunale Paratino and an unnamed road to the north of it. Our first stop was at the Strada communale. The area exhibited a dry vegetation with numerous Serapias, Orchis and even some Ophrys species. Sadly, most of the Ophrys and Orchis had completely dried out, making it impossible to identify them accurately. Nonetheless, there were plenty of other flowering plants, including Orchis coriophora subsp. fragrans, Cistus crispus, Ononis pusilla, Sideritis italica (see picture) and Linum bienne. As we recorded these species, Rutger entertained us with a story about Ollie B Bommel (a talking bear who is a well-known Dutch literary character along with his friend, the white cat Tom Poes).

29 April 2018: Water source near a nameless road (Google map)

Ranunculus trilobus

Next to the nameless road, we came across a grassy field with a water source. After encountering the knee-high prickly vegetation of the Gargano, it was a pleasant change to be in an area with short grass and tiny plants. The field turned out to be rich in various clover species, such as Trifolium micranthum and Trifolium ornithopodioides. We also spotted other interesting plants like Galactites elegans, Carex ovalis, Oenanthe silaifolia, Ranunculus trilobus (see picture) and Parentucellia latifolia. Underneath the trees we discovered Leucojum vernum.
   

29 April 2018: Orchid meadows near a nameless road (Google map)

High in the hills, we rediscovered the orchid field we had been passing a couple of days ago. This time we identified the orchid species as Anacamptis papilionacea, Dactylorhiza sambucina, Orchis morio, Serapias spec., Neotinea tridentata and in the adjacent oak woods Dactylorhiza sambucina. We also spotted numerous Nacissus poeticus, some of which were still in bloom. Underneath the trees, we made discoveries like Genista germanica, Carex depauperata and Thapsia garganica. It was a spectacular environment to conclude our BotanicalJourney, and we were very happy with our results. Including some species we recorded on our way to Bari airport, our grand total came to 844 different plant species. You can find the comprehensive day-by-day list of these species below.



List of the recorded plant species
