  1. Ensure connectivity between habitat patches

    A replicated, controlled study in boreal forests in 1993-5 in Alberta, Canada (Machtans et al. 1996), found that significantly higher abundances of the ten most common understorey birds were found in three riparian corridors between forest patches than in three clearcuts between patches. Only two of the ten were found nesting or foraging in clearcuts. In addition, significantly more juveniles used corridors following logging, than before, but only in one site. No more birds used the buffer strips near logged forest than similar strips near un-logged forest, when controlling for local abundances. Corridors consisted of 1-5-m of riparian vegetation and 90-110 m of forest. Visual surveys were used in clearcuts and mist nets in corridors.
