Trees and shrubs are disappearing fast in anthropogenic landscapes of Uganda. In order to promote their conservation on-farm, there is need to involve farmers. Farmers' involvement in tree/shrub management requires a clear understanding of the households' needs that trees can satisfy, the priority species to satisfy these needs, as well as tree management practices and challenges that hinder tree planting. This study was carried out to satisfy these information needs and to also determine species that are locally threatened. The study was conducted in selected villages of Arua and Kiruhura districts between June and October 2012 using an ethnobotanical approach. Our results indicate that farmers value tree products to satisfy household welfare needs of accessing food (edible fruits), generating income, and accessing construction wood. The species are multi-purpose, and the most preferred are Eucalyptus spp., Mangifera indica L., Persea americana Mill., Carica papaya L., Citrus limon (L.) Osbeck, Artocarpus heterophyllus Lam., Citrus sinensis (L.) Osbeck, Annona senegalensis Pers., Pinus spp., and Tectona grandis L.f. Most farmers maintain trees on their land in courtyards, backyard gardens, or crop fields and ranches. Tree species are threatened by destructive harvesting and clearing land for agriculture. The key challenges to intensification of tree cultivation are livestock damage, land shortage, drought, and lack of financial resources. Farmers suggested that in order to strengthen tree planting, they should be provided with inputs including seedlings, chemicals, and tools. In conclusion farmers prefer exotic tree species to satisfy household needs. Intensification of tree management will need to address a number of challenges identified in this study.

This is important because farmers own important resources for tree growing such as land. Furthermore, farmers make decisions regarding which species to maintain on their land based on assessments of how much they will benefit from growing a particular species and how such a species fits in the household's labor and input requirements (Dalle & Potvin 2004, Scherr 1995, Simons & Leakey 2004, Warner 1994. To enhance and encourage wider tree planting on-farm by farmers, therefore, the species that they value and which they want to grow and are ready to manage should be identified for wide-scale planting with scientific inputs and management practices (Dalle & Potvin 2004, Kahurananga et al. 1993. These are usually trees that satisfy household needs but which also have market potential and from which farmers can earn incomes to provide alternative sources of livelihood (Akinnifesi et al. 2008,...
