Control mammalian predators on islands
A paired sites before-and-after study on four paired study areas (72-139 km2) of >60 small islands in Archipelago National Park, southwest Finland (Nordstrom & Korpimaki 2004) found that, following the removal of up to 63 introduced and predatory American mink Mustela vison each year in 1992-3 and 1998, experimental areas had significantly higher species richness and abundance, compared to control areas. There was a significant positive relationship between the degree of isolation of the islands and species richness and abundance in control, but not experimental areas. In all areas, larger islands had more pairs and more species.
