Non‐native vertebrate predators pose a severe threat to many native species, and a variety of management programs are aimed at reducing predator effects. We sought to assess the effects of predator‐control programs by analyzing changes in prey and predator populations based on data commonly collected in these programs. We examined data from a predator‐control program that primarily targets the introduced red fox ( Vulpes vulpe...

The number of habitat conservation plans ( HCP) has risen dramatically since the first plan was written over 18 years ago. Until recently, no studies have quantitatively investigated the scientific foundations underlying these documents. As part of a larger study of HCPs, we examined 43 plans primarily to assess the availability and use of scientific data and secondarily to determine the extent of involvement by, and influence...
