Do local landscape features affect wild pollinator abundance, diversity and community composition on Canterbury farms?

Pollination is an essential ecosystem service that can be affected by habitat features in the immediate environment, termed here ‘local landscape features’. This study tested how five local landscape features (bare ground, native biodiversity plantings, homestead gardens, shelterbelts, and control areas of pasture) affect local pollinator communities on Canterbury farms. We also compared two sampling methods (flower visitation to native potted plants vs sticky traps) to determine if the sampling method affects the results of landscape-feature comparisons.

Re-examination of recent loss of indigenous cover in New Zealand and the relative contributions of different land uses

Loss of indigenous habitat is a key factor in the decline of New Zealand’s biodiversity. A recent contribution by Walker et al. (2006, New Zealand Journal of Ecology 30: 169–177) described losses of indigenous vegetation between 1996/97 and 2001/02 (some 17 000 ha) based on an analysis of changes in the Land Cover Database, LCDB1 and LCDB2, respectively.
