The objective of this paper is to describe quick and easy methods for carrying out local and national village surveys on farmers' tree planting practices in Tanzania. Data were collected during a survey on preffered tree species in the west Usambara Mountains, Tanzania in 1989 and a national survey on farmers' tree planting and species preferences was also carried out in 1995/96. Non-random sampling methods both for villages and for individual respondents proved to be the most effective as random sampling requires samples to avoid bias. Villages should be chosen together with local government staff and individual farmers with village leaders. An optimal sampling strategy for a national quantitative survey would be to maximise the number of villages and regions/districts covered, as opposed to spending more time in a fewer number of villages. Sampling is less biased and reflects a broader spectrum of the whole population. Some popular methods for small qualitative survey should be abandoned in favour of more formal methods in order to get consistent and reliable data. Key-informants should be interviewed in groups while farmers should be interviewed individually. Key-informants alone are not able to give precise information and cannot give quantitative data.
