The Role of Selected Environmental Factors on the Regeneration of (Ocotea usambarensis ) in Mount Kenya Forest, Kenya
(International Journal of Agriculture, Environment and Bioresearch, 2018)Despites the propagation efforts, density of Ocotea usambarensis has continued to diminish in the southern slopes of Mount Kenya. The species which is native in the montane forest is seldom on farm and found as remnant ... -
Influences of Human Activities on Tree Density and Diameter Distribution in Museve and Mutuluni Dryland Forest Fragments; Kitui County, Kenya
(Journal of Tropical Forestry and Environment, 2019-05-14)Forest fragments in Arid and Semi-Arid Lands are key water catchment areas and provide important ecosystem services. However, uncontrolled human activities are fast altering their stem density basal area and diameter ... -
Influence of cattle on browsing and grazing wildlife varies with rainfall and presence of megaherbivores
(The Ecological Society of America, 2017)In many savanna ecosystems worldwide, livestock share the landscape and its resources with wildlife. The nature of interactions between livestock and wildlife is a subject of considerable interest and speculation, yet ... -
Comparing Tree Heights among Montane Forest Blocks of Kenya Using LiDAR Data from GLAS
(Scientific Research Publishing, 2015)This study was designed to use LiDAR data to research tree heights in montane forest blocks of Kenya. It uses a completely randomised block design to asses if differences exist in forest heights: 1) among montane forest ... -
Stand Composition, Floristic Affinities and Plant Formations in Mau Forests
(Academia, 2014)The Mau ecosystem post-disturbance recovery process, integrity retention and resilience to future disturbances and sustainability remain unknown. In this paper, the ecosystem floristic composition, richness, diversity and ... -
