Continental‐wide prioritization of protected areas to address global and habitat‐specific goals for avian biodiversity conservationNARA Subscribed
The United Nations and European Union have set ambitious conservation goals to halt and reverse declines in biodiversity by protecting 30% of land and sea areas by 2030. Effective conservation planning requires evidence‐based spatial prioritization to maximize the coverage of species within designated protected areas. Based on a pan‐European database for occurrence and abundance of breeding birds collected in the 2010s, we app...
Threats to and management of Natura 2000 protected areas relative to agricultural practicesNARA Subscribed
The Natura 2000 (N2K) network combines biodiversity protection and socioeconomic targets. Human activities, such as agricultural practices, can affect biodiversity in N2K sites in diverse ways. Limiting activities with negative impacts while enforcing land management that supports biodiversity is crucial for effective conservation. Yet, site‐level information on how this is addressed in N2K sites is lacking. To fill this knowl...
Integrated distance sampling models for simple point countsNARA Subscribed
Point counts (PCs) are widely used in biodiversity surveys but, despite numerous advantages, simple PCs suffer from several problems: detectability, and therefore abundance, is unknown; systematic spatiotemporal variation in detectability yields biased inferences, and unknown survey area prevents formal density estimation and scaling‐up to the landscape level. We introduce integrated distance sampling (IDS) models that combine...
Building a better baseline to estimate 160 years of avian population change and create historically informed conservation targetsNARA Subscribed
Globally, anthropogenic land‐cover change has been dramatic over the last few centuries and is frequently invoked as a major cause of wildlife population declines. Baseline data currently used to assess population trends, however, began well after major changes to the landscape. In the United States and Canada, breeding bird population trends are assessed by the North American Breeding Bird Survey, which began in the 1960s. Es...
