Data from: Managing individual nests promotes population recovery of a top predator

Threatened species are managed using diverse conservation tactics implemented at multiple scales ranging from protecting individuals, to populations, to entire species. Individual protection strives to promote recovery at the population- or species-level, although this is seldom evaluated. After decades of widespread declines, bald eagles, Haliaeetus leucocephalus, are recovering throughout their range due to legal protection and pesticide bans. However, like other raptors, their recovery remains threatened by human activities. Bald eagle nests are commonly managed using buffer zones to minimize human disturbance, but the benefits of this practice remain unquantified. Within Voyageurs National Park (VNP), Minnesota, USA, managers have monitored bald eagle populations for over 40 years, and since 1991, have protected at-risk nests from human disturbance using buffer zones (200 and 400 m radius). We aimed to (1) quantify the recovery of bald eagles in VNP (1973–2016), and (2) provide a first-ever evaluation of the individual- and population-level effects of managing individual nests. To do so, we developed Bayesian Integrated Population Models combining observations of nest occupancy and reproductive output (metrics commonly collected for raptors) to estimate nest-level probabilities of occupancy, nest success, and high productivity (producing ≥2 nestlings), as well as population-level estimates of abundance and growth. The breeding population of bald eagles at VNP increased steadily from <10 pairs in the late 1970s to 48 pairs by 2016. At the nest-level, management significantly improved occupancy and success. At the population-level, management led to 8% and 13% increases in nest success and productivity rates, respectively, resulting in a 37% increase in breeding pair abundance. Synthesis and applications. There is a clear need to evaluate how management approaches at multiple scales assist in species recovery. Our study uses an Integrated Population Model to reveal the population-level benefits of a widely used, individual-based management action (protecting nests using buffer zones) on a recovering raptor

Results of a Wildlife Toxicology Workshop held by Smithsonian Institution: Identification &#x26; Prioritization of Problem Statements

*Background/Question/Methods*&#xd;&#xa;On March 13-15, 2007 nearly 50 scientists and administrators from the US and Canada participated in a Smithsonian-sponsored Wildlife Toxicology Workshop. Invitees were from academic, government, conservation and private organizations and were selected to represent the diverse disciplines that encompass wildlife toxicology. The workshop addressed scientific and policy issues, strengths and weaknesses of current research strategies, interdisciplinary and science-based approaches in the study of complex contaminant issues, mechanisms for disseminating data to policy-makers, and the development of a partner network to meet the challenges facing wildlife toxicology over the next decade. Prior to the meeting, participants were asked to submit issues deemed to be of highest concern which shaped four thematic groups for discussion: Wildlife Toxicology in Education, Risk Assessment, Multiple Stressors/Complex Mixtures, and Sub-Lethal and Population-Level Effects.&#xd;&#xa;&#xd;&#xa;*Results/Conclusions*&#xd;&#xa;From these discussion groups, 18 problem statements were developed and prioritized outlining the most important issues to address now and into the future. Along with each problem statement participants developed potential solutions and action steps geared to move each issue forward. The workshop served as a stepping-stone for action in the field of wildlife toxicology. These problem statements and the resulting action items are presented to the inter-disciplinary wildlife toxicology community for adoption, and future work and action items in these areas are encouraged. For example, it was found that ecologists would be essential in addressing the implications of sublethal or lethal effects of contaminants on wildlife at the population, community and ecosystem scales. The workshop outcome looks to generate conversation and collaboration that will lead to the development of innovative research, future mechanisms for funding, workshops, working groups, and listserves within the wildlife toxicology community.&#xd;&#xa

Nest occupancy and reproductive outcomes for bald eagle nests in Voyageurs National Park (1973-2016).

Data from repeated areal surveys of bald eagle nests. From 1973-1997, only summary records were available for each nest, each year, listing the number of times it was surveyed, whether it was ever occupied during that year, and what the final reproductive outcome was. For 1998-2016, data included detailed occupancy records and dates for each areal survey conducted each year. Columns are: (1) Year: of monitoring; (2) NestNumber: nest id; (3) SurveyDate: Date nest was surveyed (only for 1998-2016); (4) Visits: number of times each nest was surveyed that given year (also available for 1973-1997 records); (5) WaterDist_m: Distance to the closest permanent lake in meters; (6) MgmtType: 2 if nest was managed using a buffer zone (either 200 or 400 m radius) to minimize human disturbance, 1 if it was not managed; (7) OccCode: 1 if nest was observed to be occupied, 0 otherwise; (8) RepCode: 1 if nest produced one eaglet to near-fledging, 2 if it produced either two or three eagles, 3 if it did not produced any successfully
