Stoat invasion, eradication and re-invasion of islands in Fiordland

摘要: Abstract Stoats (Mustela erminea) were removed from three islands in Fiordland with traps at densities of one trap per 3.6–11 ha to determine whether stoats could be eradicated these densities, and how long eradication might take. successfully the two within 4 months start trapping. In a separate experiment, stoat also set checked for years on 19 small varying distances offshore, relationship between number caught, distance offshore length adjacent mainland coast documented. From data, we estimated likely rate re-invasion onto large such as Resolution, Secretary Coal, which are candidates future programmes. We conclude that permanent trapping networks keep numbers levels low enough allow recovery or re-introduction endangered wildlife.
