VCR-LTER Dynamics of Non-linear Ecosystem Change: Mechanisms and Ecological Consequences

A Landscape-Trophic Cascade Woody cover Raccoons Birds Cost of immigration to islands also affects Raccoon distribution Some notes on oddities. Fisherman’s Island has intensive raccoon-removal efforts and many of the nesting habitats are distant from the woody habitat. Ship Shoal and Myrtle islands are among the most difficult for animals to migrate to. A long-term increase in islands occupied by Raccoons has paralleled a decrease in islands with bird colonies
