  1. Variables in our models included: distance to forest edge (Edge), stem density of vegetation with height between 0.5–3 m (D0), percentage cover of vegetation at < 0.5 m (C0) and 5–10 m (C5)
  2. AICc Akaike’s information criterion values, ∆AICc the difference in AIC rank relative to the top model, w i the relative model weights, k the number of parameters in the model, LL log-likelihood
  3. aFull set of models for richness and abundance modelled: Edge, Edge + D0, Edge + C0, Edge + D0 + C0, Edge + D3, Edge + D5, Edge + DDBH, Edge + C05, Edge + C5, Edge + D0 + C5, Edge + D0 + C5 + C0, Edge * C3, Edge * D3 + D0, Edge * D0, Edge * D0 + C5, Edge * D0 + C5 + C0, Edge * C5, Edge * C0, Edge * D0 + C0, Edge * DDBH, Edge * C5, Edge * D5. D3 is stem density of vegetation with height between 3-5 m, D5 is stem density of vegetation with height between 5-10 m and DDBH is stem density of trees with DBH > 5 cm
