- The species are mixed up (not in pure stand) because they grow according to natural conditions.
- They have small plants like mosses and algae which grow on stems, branches because of wet conditions.
- They have hardwood species, mvule, mahogany, ebony, musizi, rose wood, ironwood.
- They have a long gestation period of 30-50 years because they are hardwood species.
- They have limited or no undergrowth because of dense canopies.
- They have climbing plants like lianas, cucumber, epiphytes.
- The trees have no wax, but they have gum, glue and rubber.
- They have very many species making them good for tourism and for environmental protection.
- They grow according to physical and natural conditions like wet climate, fertile soils, relief like lowlands, highlands and Mt. slopes.
- They have smooth barks (stems and branches).
