Milicia excelsa
Can be used in the control of erosion.
It makes a good shade tree and is useful as a roadside tree in urban areas.
The tree is nitrogen fixing and the leaves are used for mulching. [4]
The tree is also used in herbal medicine. The powdered bark is used for coughs, heart problems and lassitude.
The latex is used as an anti-tumour agent and to clear stomach and throat obstructions.
The leaves and the ashes also have medicinal uses

Cordia milenii
Cordia species are used as food plants by the caterpillars of some Lepidoptera species, such as Endoclita malabaricus, Bucculatrix caribbea, and Bucculatrix cordiaella.
The Wild Olive Tortoise Beetle (Physonota alutacea) feeds on C. boissieri, C. dentata, C. inermis, and C. macrostachya

Irringia gabonensis
Irvingia gabonensis is pollinated by Coleoptera, Diptera, Hymenoptera and Lepidoptera.
Seeds are dispersed by specialized vertebrates as elephants and gorillas. By reducing the number of those animals, the spread and regeneration of dika decreases and it becomes dependent on human planting
Various medicinal uses mostly depend on the bark and leaves. It is employed as a purgative, for gastrointestinal and liver conditions, for hernias and urethral discharge or for sores and wounds.

Entandrophragma angolense
Is a genus of eleven species of deciduous trees in the mahogany family Meliaceae, restricted to tropical Africa.
At least some of the species attain large sizes, reaching 40–50 m tall, exceptionally 60 m, and 2 m in trunk diameter.

Lovoa swynnertoni
This timber species occurs sparsely in small patches of remaining wet evergreen forest.
Major ThreatsHabitat loss and excessive exploitation of the seed-producing individuals are resulting in poor regeneration and a global population decline. Plantations have been unsuccessful because of infestation by Hypsipyla.

MAJOR THREATS
Deforestation Forest give-away for sugar
plantation (71km2) Human settlement Forest fires
BY ROBERT BOB OKELLO
SUGAR PRODUCTION THREAT
IN 2008, THE GOVERNMENT DARED TO GIVE AWAY 71KM2 OF THE FOREST LAND TO NEARBY SUGAR PLANTATION TO BOOST SUGAR PRODUCTION.
BY ROBERT BOB OKELLO
FACING THE THREATS
Citizen act through demonstrations (this stopped the give-away plans of the gov’t)
Legislations put in place to control poaching Forest rangers have been deployed to monitor the forest and
curb down cases of forest fires.Mass sensitization of the locals about the environmental
importance of forests

L.VICTORIA FACTFILE It is Africa's largest lake and has a surface
area of 68,800km2
It is the largest tropical lake in the world. It is the world's second largest freshwater lake
measured by surface area. The only larger freshwater lake is Lake Superior in North America.
Lake Victoria is about 400,000 years old.The average depth is 130 feet (40 meters) with
the deepest point being 276 feet (84 meters).

L.VICTORIA FACTFILE
Approximately 80 percent of the lakes water comes from rain. The other 20 percent comes from small streams flowing into the lake.
Geological studies have shown that the lake has dried up completely a few times in the past. The last time was approximately 17,300 years ago.
The Kagera River is the largest river that flows into the lake.
Two rivers flow out of the lake. They are the White Nile (called the "Victoria Nile" where it leaves the lake), and the Katonga River.
It’s the source of the world longest lake.
