This is one of several endemic plant species that is threatened with extinction on Socotra. The main threat is the huge numbers of goats, and their never ending need for grasses and other plants when the grasses are exhausted. If the goats are not enough, the climate change has resulted in extremely destructive cyclones – […]
This is a species that is quite hard to get up and close with as it is a vertical cliff specialist. This was no exception, except that there was a way for me to climb to it without taking a big risk. The foliage of this individual is wide, shiny and vibrant, a sign of […]
My first and only encounter of this species of vine on Socotra. A large and vital specimen, growing in the cracks of a vertical cliff by a creek where it was partly hanging, partly climbing. It is a shady and moist location, sheltered by the sun most of the day. Elevation: 240 meters. Endemic.

Inconspicuous but commonly found in sandy plains of the coast and further inland. This is the first I’ve found with flowers. It is found throughout much of Africa, Iran, Irak and Pakistan.
An invasive species, introduced by humans. Native range is Texas to Central America, Caribbean.
I was here exactly 8 years ago – 6 February 2015. There is quite a bit more water now, perhaps 1,5 to 2 meters deeper. There are few signs of the powerful cyclones Chapala and Megh that followed after my visit in 2015 and the following years. But I did not see any of the […]
Socotra is home to least 9 endemic species of Boswellia, which is a spectacular feat! They are incredible survivalists and most of them cling to bare rock as this one is, halfway into a shallow cave. The foliage is lush and is a clear sign of recent rains. Yet it is perhaps their flowers that […]
I was here exactly 8 years ago – 6 February 2015. There is quite a bit more water now, perhaps 1,5 to 2 meters deeper. The sand-washed, very bright surfaces are looking the same as in 2015. Perhaps reaching a bit further away from the water now. During a cyclone or wet winter, the water […]
A specialist that thrives in the cracks of vertical cliffs around waterways. Their roots find their way deep down the cracks and find what they need to survive. As they are out of reach for the goats on the vertical cliff faces, they are common in the canyons and grow to their full potential, which […]

The marine life around Socotra is rich and diverse, but I am focusing on the flora and fauna on land. However, I had a short window of opportunity during low tide where I encountered this red-eyed reef crab (Eriphia smithii).
Socotra’s biodiversity on land is undisputed and world famous, but it is equally diverse on the coast and in the sea. I am focusing on the terrestrial realm but had a brief encounter of the marine life during low tide here at Dihamri. This particular coral species was growing in very shallow water and as […]
A very variable species with leaves ranging from linear, as seen here, to oblong or broadly obovate. It has been untouched by the goats and is growing in a veritable herbal garden next to the tall cliffs of the northeastern Socotra. This was an unexpected joy to experience as it is very rare to find […]
Most of the Dirichletia obovatas I encountered were past their flowering, but this one had a few sweet scented tubes remaining. I can only imagine their scent filling the air at the height of flowering. Endemic. Elevation: 490 meters.
Leaves opposite or subopposite, densely reticulate on both surfaces (A G Miller). There are three Cordia species recorded (A G Miller): C quercifolia C obovate (leaves alternate, scabrid above) C obtusa (leaves alternate, glabrous above) As only C quercifolia has opposite leaves, and I am not aware of other Cordias on Socotra I think it’s […]
A vertical cliff specialist! Getting up close to one of these is for the most part difficult to impossible, as is the case here. They are often found in groups where you’ll see them ranging from tiny seedlings to fully mature giants. During the dry season it could easily be mistaken for the Socotra bottle […]
If you are near a vertical cliff and see lots of Socotra bottle trees (Adenium obesum ssp. socotranum) you should take a closer look, as they could be the Socotran fig. During the dry season it could easily be mistaken for the Socotra bottle tree (Adenium obesum ssp. socotranum), but when with leaves they are […]

Lavandula nimmoi is a favorite of the goats of Socotra, so why is this one seemingly untouched? The winter rains of this season were good and have ensured plenty of juicy grasses, which is the the top choice of the Socotri goat. As soon as the grasses are exhausted they will start picking their next […]

My first encounter of this species on Socotra, near the plateau above the cliffs of Hoq. The goats have easy access to this individual and have browsed it in the past. Fortunately there is plenty of grasses so far this year, which might provide time enough for it to grow flowers. As this was the […]
The vertical cliffs of Socotra are very important safe havens for many plant species on Socotra as there they are safe from goats. Thus they are able to grow and disperse seeds. This was my very first encounter of this species and at this location I found many individuals in a small area. All growing […]
A beautiful specimen, untouched by goats and growing to its full potential and one day filled with inflorescences. The vertical cliffs of Socotra are safe havens for many species that otherwise would have been browsed by the goats, leaving their growth stunted and the species almost unrecognizable. According to A G Miller and M Morris […]
As I neared the plateau the shade of the otherwise imposing Hoq cliffs of north eastern Socotra, the landscape opened up and the sun reached the ground in full force, yet this evergreen Aden currybush thrives at this location and was in full bloom. Elevation: 452 meters. Endemic.
This is a species that is commonly found wherever there is water. Even though this individual appears to be growing straight of of the face of the rock, it has set root in a crack that water seeps through for an extended time after the winter rains. This one is in its absolute prime, and […]
A beautiful specimen, untouched by goats and seemingly at its full potential. The vertical cliffs of Socotra are safe havens for many species that otherwise would have been browsed by the goats, leaving their growth stunted and the species almost unrecognizable. According to A G Miller and M Morris this is a species restricted to […]
A beautiful specimen of Oldenlandia balfourii, at its full potential. Usually the species is gobbled up by the goats, but at the time I visited there was still plenty of grasses to eat. Only when they have exhausted the stock of grasses will they find their next favourite species on their list. Adding to this, […]

There are 3 similar Geranium species found on Socotra: G mascatense G trilophum G biuncinatum This observation has a flower with a white centre, opposed to dark in Geranium biuncinatum and mascatense. Furthermore, this observation has what seems a mercicarp stuck in images 3 and 4 (ejected from the mature pod to the right in […]
A vibrant, healthy and quite tall Punica protopunica, found next to the walls of the north east of Socotra. These vertical cliffs provide shade and moisture for much longer than the exposed part of Socotra, and thus the species that grow here, next to the wall, are very healthy. Endemic.
The shape of the leaves provides information that this is a species and an individual with a huge growth potential. This is a twining plant that can grow to several meters in length. However, this seedling set root in an shallow crack in the limestone. Unless its roots can reach deep enough to reach the […]
A very young individual, with very little reserves to lean on as the moisture withdraws. The leaves turn autumn red and wither, leaving an inconspicuous plant in wait for the next trigger to continue its growth to a giant. It grows very little per year. Compared to the mature giants of the species (reaching over […]
The north-facing cliffs of the north-west of Socotra are home to many species that thrive in the cracks of the vertical cliffs. They are out of reach for the goats, and they enjoy water seeping through the cracks long after the winter rains. I found a few of this species near a considerable group of […]
I’ve noticed this species much less frequently than those of the Socotra Mabuya (Trachylepis socotrana) and Socotra Rock Gecko (Pristurus sokotranus). At each encounter I found them on the shady side of tree trunks, where they observed my presence diligently. Endemic.
Very few plant species on Socotra grow such large leaves as the ficus vasta. Fully grown it is also one of the largest of the trees on Socotra. In the dry season this is a tree without leaves, as it is deciduous. For the time being this one has sufficient moisture from the vertical cliffs […]
Found widespread around Socotra where there are shady and moist places, but I’ve seen it most commonly around the vertical cliffs of the northeastern Socotra. It will wither without sufficient moisture and wait for the return of the winter rains to start anew. It’s also found in Djibouti, Eritrea, Ethiopia, and Sudan Elevation: 422 meters.
This specimen of Oldenlandia balfourii is growing alongside the fern Adiantum balfourii, and appears vital and at its full potential. Unfortunately it bears the scars of the ever present goats, but as there is still plenty of grasses it has not been completely decimated. Endemic. Elevation: 422 meters
Due to the very high numbers of goats on Socotra, many endemic and already endangered species have just one last option for survival – the vertical cliffs! For those species specializing on growing in these harsh conditions this is their normal habitat, but for those that normally would thrive on the ground, but find a […]
The vertical cliffs of Socotra are very important safe havens for many plant species as there they are safe from goats. Thus they are able to grow and disperse seeds.

A large, lush and vital specimen of this species as it is growing out of reach for the goats. I’ve encountered it in rocky slopes where they are browsed by the goats, and never seen a specimen this large and vital. The vertical cliffs of Socotra are a safe heaven for many plant species that […]
The vertical cliffs of Socotra are very important safe havens for many plant species on Socotra as there they are safe from goats. Thus they are able to grow and disperse seeds. Unfortunately this individual was growing within reach for the goats, and as a result it has been thoroughly browsed. There are a few […]
The vertical cliffs of the north-east Socotra are home to many plant species that thrive in the protective shadow of the tall cliffs, which also provide water seeping out of cracks long after the winter rains. During my visit I walked in a field of flowers tall and vital from all the winter rains, which […]
Endemic.
The bitter tomato is found throughout Socotra, from sea-level to well above 700 meters. Found in most of Africa, Arabia, Iran, Pakistan and India Elevation: 388 meters.
This specimen looks similar to ballochia rotundifolia, seen here, but the habit is quite different. This one is tall, perhaps 150 cm tall, with few branches, opposed to ballochia rotundifolia’s almost mat-forming growth with its dense network of branches. It rarely grows taller than half a meter when not browsed by goats. Goats do come […]
Most of the Dirichletia obovatas I encountered were past their flowering, but this one had a few sweet scented tubes remaining. I can only imagine their scent filling the air at the height of flowering. Endemic.
Easily distinguished from croton socotranus by the large leaves Elevation: 393 meters. Endemic.
A very healthy specimen of polycarpaea paulayana. It is growing near the Hoq cave of the northeastern coast of Socotra, and has very little sunlight, but plenty of water so it is unclear if it would have a different habit and appearance if under the open sky. Elevation: 400 meters. Endemic.
Looks similar to Paraerva revoluta, but stems and leaves are glabrous (without hairs), opposed to P revoluta where stems and leaves have woolly hairs or short matted hairs – see this observation. Furthermore P revoluta is normally found on granite slopes of the Hagghier mountains, this is at 389 m elevation on limestone cliff. Endemic.
Native range is Egypt to Tanzania, West Asia to Northwest India, Arabian Peninsula, West Indian Ocean.
I encountered this one close to a vertical cliff that blocks the sun for many months of the year where only the early morning rays reach the ground. In addition to the protective shade the cliff is a source of water seeping from crack and in many places constantly dripping to the ground. This perfect […]
Native range is Ethiopia, Eritrea, Socotra, Arabian Peninsula.
The fact that species of orchids are found on Socotra is a testament to the wealth of opportunities for life here. At first glance it is an arid island, yet there is always water present. Some locations all year round, others after the winter rains. This is the most common of the orchids on Socotra, […]
Tragia balfourii is a species advertising a sinister side to it – stinging hairs, just like a stinging nettle. I did not have an encounter with its stings, as I did not brush against one, nor wore shorts, but I have no plan on feeling a sting. This is a male plant. Endemic.
In places commonly seen on socotra, like this one alongside the trail to Hoq cave.
Native range is Socotra and North Somalia
The trail to Hoq cave is a great place to see the Socotra mabuya, as they are easily seen from the trail. Endemic.
The endemic Socotra Mabuya and the Socotra Rock Gecko (Pristurus sokotranus) are species commonly seen in the same landscape throughout Socotra.
This parasitic plant is found throughout Socotra, from sea-level and up to about 700 meters. This is individual growing on the slopes below the Hoq cave. It is found throughout Africa, Arabia, Pakistan and India . Elevation: 133 meters.
The diversity of life on Socotra is incredible and the plant species endemic to the island rivals that of the Galapagos islands. A whopping 37% of Socotra’s around 830 plant species are endemic – they exist nowhere else in the world. When it comes to land snails it is even more incredible. A staggering 95% […]
This parasitic plant is found throughout Socotra, from sea-level and up to about 700 meters. This observation is from the slopes below the Hoq cave. It is found throughout Africa, Arabia, Pakistan and India . Elevation: 132 meters.
A species with winding and twisting branches, with smooth, grey bark. Found throughout woodlands of Socotra up to near 1000 meter elevation. This tree was home to a large colony of bark snails (Achatinelloides). Endemic.
Endemic.
I encountered this species in two locations. Only this one was in its prime, albeit the smallest. It is also found in eastern Africa, Arabia to India.
I encountered two individuals of this species near each other here in Erissel, Socotra’s east-cape. This is my first and only encounter of the species so far on Socotra. It is found in dry vegetation areas in Africa, throughout the Arabian peninsula to India.
These towers are made by the male Red Sea Ghost Crab (Ocypode saratan). The crabs are found on the coast throughout Socotra, but they are only able to make these castles where the tides do not regularly reach. Here in Erissel they dig deep to reach the wet sands, and thus these towers reach pretty […]
Erissel is the easternmost point of Socotra. It is a windswept low-lying area governed by the elements. During cyclones the wind and sea wreak havoc on the landscape here, reshaping everything. Only the hardiest of plants and animals thrive here. The Red Sea ghost crab is well adapted to these changing conditions and in most […]
The north-facing beach of the tip of Erissel is wide and deep, with a large part only tasting the waves during monsoons. This is perfect conditions for the male Red Sea ghost crabs, as they can create these towers undisturbed by the tides and waves. The crabs only have to deal with the effects of […]

Erissel is the only place on Socotra (so far) I have encountered this species. It grows as a small colony in the sand dunes and I have not seen any signs of it spreading outwards (since I was here in 2015). Instead I found it to have shrunk somewhat, likely due to the severe cyclones […]
A really old individual holding on to life in harsh conditions, compared to the lush, vibrant and large specimens found in sands of Arher. Also found in mainland Arabia.
This species is usually found sporadically, but in some places you can find many in a limited area. Here in Erissel they grow in large numbers in a restricted area of rocks where they are found in an amazing variety of growth. Endemic.
