Forest utilization by humans is widespread and often results in environmental degradation. This dissertation aimed to help provide the understanding necessary to achieve the sustainable utilization of 13 forests in West Usambara, Tanzania. First, I examined forest disturbance by local people (Chapter 2), then determined if the disturbance was harmful to wildlife (Chapter 3), and finally, investigated if participatory forest management was an appropriate conservation strategy in West Usambara (Chapter 4). Disturbance was ubiquitous, but variable in West Usambara and I found that utilization was highest in areas of high population pressure. In terms of wildlife, Colobus angolensis palliatus monkeys appeared to have become extinct in three small forests with intense removal of poles (i.e. small trees), which implied that utilization may be unsustainable. However, the effects of pole removal may be different than the effects of tree removal as I recorded high encounter rates with the monkeys in areas of intense tree removal. The results from Chapter 2 and 3 suggested that conservation efforts were necessary in West Usambara, and therefore I examined if participatory forest management was an appropriate conservation strategy. I found that most local people knew that forest utilization was detrimental to the forest, and many supported the conservation of forests, which together indicated that local people may be able to manage forests effectively and sustainably. I also found that large farms were associated with high support for conservation. The mechanisms that connect farm size to support for conservation are not clear but the results implied that increasing access to non-forest resources may lead to increased support for conservation. In conclusion, I found that the forests of West Usambara were highly utilized by local people, a focal wildlife species was negatively affected by forest disturbance, and participatory forest management was a sensible conservation approach.
