  1. Provide or retain un-harvested buffer strips

    A replicated, randomised, controlled study from May-June in 2001 and May-July in 2002 in 24 buffer-strip blocks and 18 continuous, old-growth forest blocks in coastal, temperate forests in Alaska, USA (Kissling & Garton 2008) found that species richness was similarly distributed across treatments and controls (both averaged 15 species / 100 detections). Species richness and diversity were greatest in the narrowest buffers (< 100 m) but species composition in the largest buffers (? 400 m) was most similar to that in control blocks. Only 3 of 10 common species differed in abundance across buffer treatments and controls (2 were positively and 1 was negatively related to buffer width). The authors conclude that forested beach buffers ? 250 m wide can support densities of forest-associated birds similar to that of natural stands but rare or uncommon species will benefit most from buffers ? 400 m in width.
