Data from: Population genomics of Sitka black-tailed deer supports invasive species management and ecological restoration on islands

Here we use restriction-site associated DNA sequencing (12,947 SNPs) to investigate connectivity and gene flow of invasive deer (n=181) across 15 islands, revealing little structure throughout Haida Gwaii and identifying the large, central island of Moresby (>2,600 km2) as the greatest source of migrants. As a result, the archipelago itself should be considered the primary eradication unit, with the exception of geographically isolated islands like SGang Gwaay.

Thus, limiting eradications to isolated islands combined with controlled culling and enhanced biosecurity may be the most effective strategies for achieving ecological restoration goals.
