A map showcasing the tree cover in Kenya (average canopy height of 3m).
While Kenya has limited forest cover (only 6%) the country has a significant canopy coverage that is not necessarily forest. @KeForestService classifies forests as areas having > 30% tree cover.
Thread.
It goes without saying that the areas with the highest average canopy height and forest coverage are the main water towers in the country (Mt. Kenya, Aberdares, Mau and Cherangany Hills).
Mt. Elgon on the Uganda border also ranks in this category.
The main water towers are highland areas. In adjacent localities, highland relief rainfall and good soils support agricultural activities. While limited in size, these areas are some of the most densely populated. Kericho (pictured) adjacent to Mau is an example.
Areas with limited canopy coverage tend to be savanna or (semi) deserts. Aside from Chalbi & Taru deserts, the highlighted areas are low-lying savanna/semi-arid areas that support great pastoral herds. These include counties like Tana River, Garissa, Isiolo, Marsabit & Turkana.
Mandela, Wajir and sections of Marsabit county (near Moyale) have significant canopy coverage relative to other areas in northern Kenya. Incidentally, these are also the areas with the largest camel herds which largely graze on trees.
Finally, the only areas in the North (outside of Wajir and Mandera) that have significant canopies are river valleys. These are found along Turkwel, Kerio, Ewaso Nyiro and Tana rivers.
End.

Prosopis juliflora or Mathenge is an exotic drought-resistant tree of American origin that has been widely used for afforestation in Northern Kenya.
A thread on how the aggressive tree species has proved destructive to the pastoralist economy.
The trees have pods that are eaten by livestock and spread over large areas where they quickly grow. The deep tap roots of Mathenge trees ensures the trees stay evergreen once they take root.
The tree particularly thrives along water sources such as rivers banks & flood plains.
The trees colonize whole areas forming thick, impenetrable bushes that restrict access to grazing land and water sources.
Small animals like goats and sheep frequently get lost in the thickets to be devoured by wild animals.
A hydrological map of Kenya with colour-coded watershed areas.
In this thread, we'll highlight the source of each river, the watershed area and the direction of flow.
The rivers of Kenya flow from three main sources: the escarpment and highlands east of rift valley (Aberdares), highlands west of the rift valley (Mau) and Mt. Kenya.
Mt. Elgon & Kilimanjaro on the border with our neighbors also act as sources of rivers that flow within Kenya.
The rivers that rise from the western escarpment and western highlands flow west into major rift valley lakes. These include Nzoia, Yala, Kuja (Migori), Sondu and Mara that flow into Lake Victoria.
Turkwel (Mt. Elgon) and Kerio (Elgeyo escarpment) flow north to Lake Turkana.
The @Space_Station flies some 400kms above earth. In this video, the ISS flies from the Iberian Peninsula to Kenya on a bright, moonlit night.
We've taken some screenshots and tried to highlight some of the cities and geographical features visible.
THREAD.
The flight starts above Spain and Portugal.
Mediterranean cities are visible due to their bright city lights including it's largest city, Barcelona as well as Northern Italy's largest city, Milan.
Europe's highest mountain, the Alps mark a dark patch North of Italy.
As the flight progresses, the entire Italian peninsula comes into view including it's capital, Rome.
The city of Naples is also visible as is the island of Sardinia.
