Grade 6 Social Studies Natural And Built Environmemt – Vegetation In Eastern Africa Notes

Vegetation in Eastern Africa

Topic: Natural and Built Environment — Subject: Social Studies — Age: 11 (Kenya)

What is vegetation?

Vegetation means the plants that grow in an area. This includes trees, grasses, shrubs and crops. Vegetation may be natural (wild forests, grasslands) or planted by people (tea or tree farms).

Main types of vegetation in Eastern Africa

• 🌳 Forests — tall trees that form a canopy (e.g., Mount Kenya and Aberdare montane forests).
• 🌾 Savannah / Grasslands — grass with scattered trees (e.g., Maasai Mara, Amboseli).
• 🏔️ Montane and alpine plants — plants that grow on high mountains (upper slopes of Mt. Kenya).
• 🌊 Mangroves — trees that grow in salty coastal water (found along Kenya’s coast: Mombasa, Lamu).
• 💧 Riverine vegetation — plants that grow along rivers (e.g., along the Tana River).
• 🌵 Dryland scrub and thorn bush — in semi-arid areas of northern Kenya (Turkana, Moyale).
• 🌿 Cultivated vegetation — farms and plantations (tea in Kericho, coffee, maize, sisal).

Where these occur in our region

- Highlands: more rain → forests and tea/crop farms (e.g., Central Highlands, Kisii, Kericho).
- Rift Valley & open plains: grasslands and savannah → good for wildlife and grazing (e.g., Maasai Mara).
- Coastal strip: beaches and mangroves (Mombasa, Kilifi, Lamu).
- North and north-east: dry scrub, acacia trees, and thorny bushes (Turkana, Garissa).

Why vegetation is important

• Food for people and animals — crops, fruits and pasture for livestock.
• Homes and tools — timber, poles, thatch for houses and fences.
• Medicine — many local plants are used as traditional medicine.
• Climate and water — trees help rain water soak into the ground and reduce floods.
• Soil protection — roots hold soil and stop erosion.
• Tourism — savannahs and forests attract visitors (helps our economy).
• Shade and cool towns — trees in towns make places cooler and healthier.

Threats to vegetation

Vegetation in Eastern Africa faces many problems:

• Deforestation for farms, houses and charcoal.
• Overgrazing by many animals — leaves the land bare.
• Urban growth — towns remove trees and fields to build roads and houses.
• Climate change — droughts make it hard for plants to grow.
• Poor farming methods — cause soil to wash away and plants to die.

How we can protect vegetation

• Plant trees (tree planting days at school and in the community).
• Control grazing — move animals to new pastures (rotational grazing).
• Use wood wisely — avoid cutting too many trees; use fuel-saving stoves.
• Protect mangroves — they protect the coast from waves and provide fish nursery areas.
• Support community conservancies and national parks (laws help protect forests).
• Practice agroforestry — grow trees and crops together on farms.

Vegetation and the built environment

Vegetation and buildings are linked. Trees provide timber for houses and shade for streets and markets. Parks and planted trees in towns make places nicer and healthier. When trees are removed, towns can become hotter and dusty.

Class activities and questions

1. Draw a simple map of Kenya and colour the areas where forests, savannah and mangroves are found.
2. List three plants used in your home for food or medicine.
3. Match: write the correct place — (a) Mangrove — (b) Montane forest — (c) Savannah. Choices: Mt. Kenya, Mombasa coast, Maasai Mara.
4. Discuss: How can your school help to protect local vegetation? (Make a short plan.)

Glossary (short)

Vegetation — all the plants in an area.
Mangrove — a tree that grows in salty coastal water.
Savannah — grassland with a few trees.
Deforestation — cutting down many trees.

Teacher tip: use local examples from your county (trees, farms, parks) to make the lesson real for the pupils.
