Replication data for: Exotic tree species displace indigenous ones on farms at intermediate altitudes around Mount Kenya

Exotic tree species displace indigenous ones on farms at intermediate altitudes around Mount Kenya highlands and upper midlands, whereas indigenous species in the lower midlands and lowlands. As the frequencies of most indigenous trees were low, only parts of the surveyed farms can contribute to conservation of tree genetic resources, particularly the less intensively managed farms of the more arid lands. Farmers access to knowledge on valuable indigenous tree species and to quality seedlings of these trees need to be improved to increase indige- nous species™ frequencies on farms and possibly to replace some of the exotic species in the future.
