TBG manages plant seedling nursery with a diversity of plant species which include: Ornamental plants, Herbs and Spices, succulent plants and tree collections. The tree seedlings are mainly indigenous with few selected exotic species. The nursery raises over 300,000 plant seedlings which are either planted in restoration sites, donated to the local community and institutions, or sold to private planters. Seeds are collected with the help of communities from neighboring primary forests, community forests and TBG mature stands.
The organization concentrates on indigenous species because of the benefits that come with them. These include supporting many species of flora and fauna, and providing wider socio-economic benefits in the form of non-timber forest products, protecting water sheds and water quality by controlling soil erosion and moderating floods. TBG raises selected exotic tree species on site, for example, the candlenut tree (Aluerites molucanus), Bottle brush species (Callistemon spp), Jacaranda mimosfolia, Grevillea robusta, Eucalyptus spps and Neolomakia cadamba (Barthedevia), which date back to the colonial era, still shaping Uganda’s history and landscape. In addition, they are used for commercial plantations for electricity and building poles for communities’, fuelwood, quick timber products among others hence reducing pressure on the natural forest species for such demands.
