Resource and Landscape Use of Insects Pollinating Trees in Natural Forest Fragments

This project has two components: ecological and social.

Ecologically, we aim to rehabilitate forest edges back to pristine ecotones. We offer the first study on the largely undescribed antagonistic insects associated with Afrotemperate forest tree fruits and seeds, linked to germination success. Collected seeds will be germinated in a community nursery and used in landscape rehabilitation.

Socially, we engage local communities through environmental education, nursery expansion, and landowner agreements. The nursery will be based in Covie, a previously disadvantaged community with strong local ecological knowledge, skills, and space. This integrated approach supports biodiversity and community-led restoration in Afrotemperate landscapes.

A major threat to Afrotemperate forests is edge degradation (Wilson et al. 2010; Swart et al. 2018; Giddey et al. 2021). Linked to this is a decrease in natural ecotones with the creation of hard edges, bearing in mind that Afrotemperate forests are naturally fragmented – and the ecotones are biodiversity hotspots.

Our intended work will fill this niche, via: 1) implementing edge rehabilitation across our core area of influence, 2) studying seed-associated insects, 3) calculating germination rates of different species, and 4) establishing with collected seeds a nursery specializing in pioneer, edge species.
