Report of this BotanicalJourney
29 and 30 June: The German island Rügen (Google map)
The ferry departed from the island of Rügen, so we first set up our tent in the vicinity of a German town called Binz. This experience was somewhat surreal for several reasons. First, a massive thunderstorm unleashed itself above our tents during the night, flooding parts of the campsite. Nevertheless, the next morning —still far from dry— we decided to explore the dunes near Prora. Prora, originally intended as a holiday resort by the former Nazi regime, was built in the 1930s but had long been neglected. Recently, a significant portion of the complex (originally spanning 4.5 kilometers) has been renovated and now serves as a hotel and holiday apartments.That was the second surreal aspect of the location.
Further north lies a large flint field known as “Schmale Heide.”
This forest strip grows along parallel rubble walls formed by
flint stones that were once washed up on the Baltic Sea beach.
Nowadays they form a dry heathland with Calluna vulgaris,
Juniperus communis and Empetrum nigrum. In this
somewhat otherworldly environment, we recorded Petrorhagia
prolifera, Genista pilosa, Tragopogon arvensis
(see picture) and Teucrium scorodonia. In the surrounding
forests we found species like Rosa multiflora,
Brachypodium sylvaticum and Convallaria majalis.
Fortunately, the rain stopped around midday.
We made a brief stop in the Mukran harbor area. We arrived a little early at the ferry terminal and spent our time exploring a deserted road within the harbor. This turned out to be a successful choice: many plants were present, although they were all common species. For example, we recorded Scorzoneroides autumnalis, Lathyrus pratensis and Malva moschata at this location. Needless to say, the German species mentioned do not count toward our Danish Bornholm list.
30 June, 1 July and 4 July: Teglkåsvej (Google map)
Next to a house, we noticed a small stream with Circaea x intermedia growing in it. Rutger jumped down to capture photos of this species. A man with his dog curiously observed Rutger, saying “Hej”, then turned and left without further communication. It marked our first direct encounter with a Danish local.
1 July: Deciduous forest at Slotslyngen (Google map)
As we drove north from Hasle, we noticed small ponds and streams nestled within a forest primarily composed of Quercus petraea and Carpinus betulus. We followed the tracks through the forest, recording the presence of some typical forest plants such as Melampyrum pratense, Oxalis acetosella, Circaea lutetiana, Convallaria majalis and Stellaria holostea.
1 July: Sandvig (Google map)
1 July: Spellinge Mose (Google map)
In Danish, “mose” means “swamp,” so you can imagine what “Spellinge Mose” was like. We parked our car in the woods and followed a path that circled around the swamp. Despite the abundance of mosquitoes, we managed to record several new plant species. In the swampy areas, we found Carex pseudocyperus, Spirodela polyrhiza and Schoenoplectus lacustris for example.
1 July: Rubinsøen (Google map)
On the other hand, the lake known as Rubinsøen did not live up to our expectations. This lake is a former lignite mine that is now filled with water. The only new species we recorded there was Quercus rubra.
1 July: Around the pier of Hasle (Google map)
On our return journey, we decided to make a brief stop at the pier of Hasle. Unfortunately, the vegetation had been recently mowed, so we were hardly able to discover any new plant species. The adjacent town itself also did not yield many new species. We recorded species like Lepidium draba, Puccinellia distans and Spergularia marina. Afterward, we returned to our holiday apartment. On this first full day, we managed to expand our Bornholm species list to 444 different plant species. We were quite pleased with this preliminary result.
2 July: Raghammer Skydeterræn (Google map)
The following day, we decided to visit the southernmost point of Bornholm, characterized by steep sandy dunes (and numerous holiday homes). Our journey took us through the town of Rønne, where we recorded several species alongside the road, such as Petasites hybridus, Verbascum speciosum and Sedum rupestre. Our first significant stop was at Raghammer Skydeterræn. This military domain, located on the island’s south coast, is composed of low dunes, forests, and grassy meadows. There are multiple entrances to the area, each marked with signs that, albeit somewhat incomprehensible, provide guidance on where and when you can enter. The signs mentioned something about green lines on a map, but these lines were not visible due to sun fading. Even within the Raghammer Skydeterræn, there were no clear signs indicating restricted areas.
2 July: To the beach at Dueodde (Google map)
To
reach the southernmost point of Bornholm, you must venture to the
vicinity of Dueodde. Walking paths extend from the paved road
towards the beach. This area can get a bit crowded, and if you’re
looking to purchase souvenirs or enjoy an ice cream, you’re
definitely in the right place. However, we had other interests and
followed a rather busy path southward but deviated from it at
several points. Initially, we encountered a marshy environment.
Further south, the path meandered through a pine forest. We
strayed from the path and discovered the spectacular Goodyera
repens (see picture). It was quite abundant! Some
specimens exhibited yellow markings on their leaves, which are
considered to be a variation of the species. In the dunes with
bare sandy soil, we recorded species like Festuca juncifolia,
Erigeron acris and Epilobium tetragonum as well.
2 July: South of Nexø (Google map)
Our third stop of the day was slightly south of Nexø, where we had identified some ponds and marshy fields on our map. We parked the car at a cemetery and followed a trail into the woods. Here, we identified species like Viola odorata, Symphytum x uplandicum (S. asperum x S. officinale) and Geranium pusillum. Scattered through the area we found small ponds, consisting of rain water that was collected in rocky pits. We found species like Lythrum portula, Potamogeton friesii, Carex riparia and Butomus umbellatus there.
2 July: Ølene Fuglereservat (Google map)
We wrapped up our day at the Ølene Bird Reserve. Like our previous
destinations, we selected this location based on the visible ponds
on our map. Ølene turned out to be a real gem! A significant
portion of the reserve was inhabited by Cladium mariscus.
However, the area sandwiched between the forest edge and the Cladium
mariscus yielded numerous exciting discoveries. For
instance, we documented the presence of Pinguicula vulgaris
(see picture). There were also other species that are adapted to
wet environments, such as Galium boreale, Utricularia
vulgaris, Baldellia ranunculoides and Gentiana
pneumonanthe.
As we retraced our steps to the trail to ascend a bird tower, we were pleasantly surprised to find Pyrola minor. Other notable discoveries included Valeriana dioica, Arnica montana and Galium boreale. The area was abundant with various sedges, like Carex disticha, C. lasiocarpa and C. hostiana. As the weather turned colder and rainier, we decided to head back to our car. We left Ølene Bird Reserve feeling extremely satisfied with our findings!
3 July: Hammershus (Google map)
Situated relatively close to our holiday home was “Hammershus,” the ruins of a Medieval castle. Judging by the size of the parking lot and the visitor center, it appeared to be quite bustling during the summer. We visited the area on a tranquil day that began with a refreshing drizzle. Consequently, there were only a handful of other visitors at Hammershus. Our exploration began on a narrow path that descended steeply through a forest. We recorded Hieracium murorum, Lamiastrum galeobdolon and Mercurialis perennis in this area.
3 July: Langebjerg (Google map)
Our subsequent destination was Langebjerg, situated near the town of Sandvig, a place we had also visited on July 1st. According to local folklore, the hill is home to a troll named Krølle Bølle, his father Bobbarækus, his mother Bobbasina, and his sister Krølle Borra. Langebjerg piqued our interest as we drove past it from a distance, prompting us to explore the reserve. The experience was truly rewarding! With no clear paths in sight, we navigated across the hill randomly, discovering species like Filipendula vulgaris, Polygala vulgaris and Orchis mascula.
3 July: Along the northeastern coast (Google map)
From Sandvig, we traced the northeastern coastline of Bornholm, moving southward. We made several stops, primarily where freshwater streams cascaded down from the hills. Our initial stop was at Døndalen. This location was quite bustling, with numerous families strolling through the woods. We only documented a few new plant species here, such as Veronica montana and Equisetum hyemale. The presence of Asplenium trichomanes was somewhat noteworthy, given that we hadn’t encountered it anywhere else on the island.
Our
third stop along the northeastern coastline was at Saltune, where
we documented Stellaria nemorum, Anthyllis vulneraria and
Serratula tinctoria (see picture). Our final stop was at
Bølshavn Havn. The environment there reminded us somewhat of the
seaside grassy fields at Sandvig. We observed a unique mix of
freshwater plants and salt-tolerant species. We recorded species
such as Lotus maritimus, Ononis spinosa subsp. procurrens
and Veronica catenata, which were found alongside Triglochin
maritima and Bolboschoenus maritimus. A remarkable
discovery was Primula farinosa, a species we did not
expect to find on Bornholm. These plants were accompanied by Epipactis
palustris, another rare find on the island.
3 July: Bastemose (Google map)
In our quest for wet habitats, we ventured further into the inland areas of Bornholm. We identified a marshy area on the map, known as “Bastemose”, which featured a bird-watching tower and a wooden walkway traversing the marsh. The path led us through a forest on both sides of the marsh, where we documented Neottia ovata.
In
the marsh itself, we recorded species like Hydrocharis
morsus-ranae, Sium latifolium, Stratiotes aloides and Hottonia
palustris. While Rutger was busy photographing Carex
appropinquata, Jeroen decided to take a quick nap in the
sun, lying down on the wooden walkway. A woman who noticed this
rushed towards us, thinking there was an emergency. However, since
Carex appropinquata had already been identified, the
perceived emergency had been effectively addressed. In the forest
on the west side of Bastemose we were pleasantly surprised by the
discovery of Trientalis europaea (which had no flowers,
unfortunately - see picture).
4 July: Svartingedalen (Google map)
Relatively close to our holiday home was a valley known as
Svartingedalen. A quaint stream, Baggea, meandered through this
valley. In our quest for discovering new species, we decided to
explore it. Svartingedalen turned out to be a charming forested
valley. We identified some new plant species in the dense forest,
such as Paris quadrifolia, Anemone ranunculoides, Lonicera
xylosteum (see picture), Dryopteris expansa and Ranunculus
auricomus. About halfway into the valley, we came across a
grassy field inhabited by cows. Two men with noisy machinery were
busy mowing the grass. In a nearby pond, we documented Carex
acutiformis and Lemna turionifera. Beyond this
point, the valley transitioned back into a forest. Here, we once
again encountered Paris quadrifolia.
4 July: Rønne city (Google map)
Our species list was brimming with a variety of plants, but we were still short of our goal of identifying 750 different species. This led us to consider new habitats that we hadn’t visited before. We set off to the nearest large town on Bornholm, Rønne, hoping to discover several plant species typical of human-influenced areas. While we didn’t record any plants in gardens, we did take note of all escapees, such as Erysimum cheiri, Verbena bonariensis, Antirrhinum majus and Parietaria judaica.
4 July: Ringebakke (Google map)
Another location in close proximity to our holiday home was Ringebakke. Here, we discovered a forest-covered valley named Blaskinsdalen, carved out by a small stream. We embarked on a journey along a narrow path leading to a chapel, where we first recorded Petasites albus. As the path meandered closer to the sea, we discovered species like Rosa villosa and Melampyrum arvense.
As the valley came to an end, we traversed through some deserted
quarries. By this time, a robust wind had picked up and it was
raining quite heavily, making our plant exploration somewhat
uncomfortable. Despite the conditions, we managed to record
species like Juncus ranarius, Barbarea intermedia and Cotoneaster
horizontalis (see picture). Upon reaching the second quarry,
which was the most northern one, we were disheartened by the
inclement weather and decided to retreat to our car. However, just
as we were about to leave, a light green leaf rosette with spiny
leaves caught our attention. It was Carlina vulgaris, a
delightful species that perfectly concluded our day. Drenched, we
made our way back to our car and returned to our holiday home.
5 July: Safirsøn (Google map)
We continued our search for wet environments, believing they
offered the best opportunity to expand our species list. Our
journey took us to a lake named Safirsøn, located just south of
our holiday home. This area is recognized for the presence of Chimaphilla
umbellata, a plant neither of us had encountered before,
sparking our eagerness to find it. We did locate it, but were
slightly disappointed to find only leaf rosettes visible; the
flowers were yet to bloom (see picture). It puzzled us why the
species was confined to a single location in the forest,
as the rest of the forest seemed equally suitable to us. The area
was dotted with several interesting species, including Lathyrus
linifolius and Melica uniflora.
5 July: Lilleborg (Google map)
We
took a brief break at Lilleborg, the ruins of a medieval castle
perched on a hill and surrounded by water. The castle was
constructed in 1190 by King Knud VI. Today, only a few remnants of
the castle remain, primarily low stone walls. However, in the
water surrounding the former castle, we discovered Sagittaria
sagittifolia. In the adjacent forest we found Alchemilla
glabra (see picture) and Lysimachia nemorum. Our
original plan was to walk from this site towards Ekkodalen.
However, due to the scarcity of new species in the intervening
forest, we decided to return to our car and drive to Ekkodalen
instead.
5 July: Ekkodalen (Google map)
Ekkodalen is a well-known nature reserve, shaped by volcanic activity in the past. Today, it attracts many visitors who take the valley’s name quite literally: “ekko” translates to “echo,” prompting many visitors to shout aloud during their walk through the valley. This often results in the valley echoing like the monkey house at our local zoo. As you can imagine, our visit to Ekkodalen was somewhat disappointing due to this. However, we had a rather pleasant encounter with a roe deer that was hiding from us, seemingly trying to protect its offspring. We hadn’t noticed the mother and child until we were quite close, at which point they decided to flee. We hope they were able to reunite after we left. We recorded Verbena officinalis, Gnaphalium sylvaticum and Rubus nessensis in Ekkodalen and decided to leave the monkey house as quickly as possible.
5 July: Hestehave (Google map)
Two days prior, we had ventured to another marshy area referred to as “Hestehave” on our topographic map. Our initial attempt to explore the swamp was thwarted by the challenging terrain, lack of paths in the wet area, and the presence of cows and their guardswoman. We only managed to record Rubus saxatilis. However, undeterred, we decided to try again. Having figured out how to access the area, our second attempt proved successful.
5 July: Pedersker Jagdhuset near Ølene Fuglereservat (Google map)
5 July: Kodalen in Paradisbakkerne (Google map)
Paradisbakkerne is another renowned nature reserve on Bornholm.
It’s characterized by hilly, rocky terrains with slender rift
valleys, enclosed by vertical cliffs. We were pleasantly surprised
to find that only a few other people were around, making
Paradisbakkerne far from a monkey house. In fact, Kodalen (part of
the Paradisbakkerne area) was a stunning valley encircled by steep
rocky slopes. We documented Carex pallescens and Platanthera
chlorantha here. On the rocks we observed Asplenium
septentrionale (see picture), a species we knew could be
found in Kodalen.
5 July: Along the eastern coast (Google map)
Our
tour along the northeastern coast on July 3rd had been quite
enjoyable. So we decided to explore the coast a bit further south
as well, visiting three distinct areas ranging from Årsdale to
Svaneke. South of Årsdale, we descended a slope dotted with large
boulders. On these boulders, we discovered Cotoneaster
integerrimus, Lepidium heterophyllum and Silene viscaria
(see picture). At the base of the slope, there was a grassy
and damp area, similar to other coastal locations we had visited.
We particularly enjoyed these spots due to the presence of both
freshwater and saltwater plants. Here, we documented species such
as Samolus valerandi, Lotus maritimus, Pinguicula vulgaris
and Primula farinosa.
Finally, we visited the town of Svaneke. We followed the coastline
and meandered through the village, documenting several new species
that had escaped from gardens or allotments. Parthenocissus
vitacea, Campanula portenschlagiana and Brunnera
macrophylla are good examples of this. One specimen of Dipsacus
strigosus (see picture) grew in the pavement in front of a
house, reaching the same height as the house itself. It was a
remarkable sight.
6 July: Motocross area Klemensker (Google map)
We began the final day of our Botanical Journey at the motocross
area of Klemensker. Upon arrival, we encountered a few men
working, so we introduced ourselves and explained our intentions.
They assured us that it was no problem for us to walk on the race
track. So, we proceeded. The grassy edges of the track were
teeming with various species. Anthyllis vulneraria was
plentiful, and we also spotted many specimens of Jasione
montana. Several Galeopsis species puzzled us, as
some seemed to form intermediate plants. We recorded Galeopsis
ladanum, Galeopsis bifida and the hybrid Galeopsis x
ludwigii (G. bifida x G. tetrahit - see picture). Filago
germanica, Filago arvensis and Logfia minima grew in
close proximity, allowing us to easily discern the differences
between these species. It was somewhat unusual to traverse a race
track, but the experience at Klemensker was certainly rewarding!
6 July: Small ponds at Kærby and Bornholms Golfklub (Google map)
As
we drove from the motocross area towards the sea, we encountered
numerous (artificial?) ponds nestled in grassy meadows or within
the premises of Bornholms Golfklub. We paused momentarily to look
for plants and recorded Ranunculus sardous (see picture)
and Cardamine pratensis subsp. paludosa here. The roads
were quite narrow, and while we were busy identifying a particular
plant, there was insufficient space for another vehicle to
overtake us. Consequently, we had to move ahead, allowing the
other car to pass, and halted in the driveway of the nearest
house. The other driver overtook us, rolled down his window, and
inquired about our activities. We explained our quest for finding
wild plants on Bornholm and showed him the plant we were trying to
identify. Following our explanation, the driver parked his car,
retreated into his house, and reappeared after a few minutes. He
handed us his mobile phone, suggesting a possible name for the
species. His guess was spot on – it was indeed Ranunculus
peltatus.
6 July: Sose strand (Google map)
During this year’s Botanical Journey, we had only visited the southern coast of Bornholm on one occasion. To rectify this, we decided to explore Sose Strand ("strand" translates to “beach”). The initial part of the trail was perched high above the sea level, atop sandy cliffs that appeared precarious and ready to collapse at any moment. Fortunately, no such incident occurred, and we were able to record Campanula persicifolia here. The adjacent cornfield proved to be a valuable source of several weeds.
6 July: Kærgårds mose (Google map)
Another
marsh, known as Kærgårds Mose, was on our itinerary. Our
exploration began on a rather unusual spot near the parking area,
where we discovered a variety of naturalized garden plants. These
plants seemed to be thriving, leading us to speculate that the
area might have been a former garden waste pit. We documented
species like Phedimus hybridus, Iris sibirica and Pulmonaria
officinalis here. As we ventured deeper into the marsh, the
plant species we encountered were more in line with our
expectations. We were able to record some new species in this
area, such as Rosa multiflora, Inula salicina (see
picture), Cirsium acaule and Ranunculus bulbosus.
We also found Lemna gibba in a small pond.

PLEASE NOTE:
Only the first finding of species is displayed. So species that
were recorded, let's say, both on the 4th and the 5th of July ONLY
are noted on the 5th.
