Kenya has a total surface area of 582 646 km², and a population total of just over 40 million with a growth rate of 2.7% (2009 census). The total state forest area is estimated at 2.35 million ha (about 2.7% of Kenya’s land area) out of which 1.57 million ha are gazetted and 0.78 million ha ungazetted forests. In addition, there is approximately 2.1 million ha of other woodlands, 24.8 million ha of bush land and 10.7 million ha of wooded grassland. The number and volume of trees on farm are considerable in Kenya, particularly on small- and medium size farms in the highlands, but it is impossible to translate these tree resources into an area equivalent figure.
