Abstract

Context

Elevated mesopredator populations can pose a threat to species of conservation concern.

Aims

We sought to evaluate the effectiveness of raccoon removal on their abundance and on Blanding’s turtle nest success.

Methods

We used an index of raccoon abundance generated from camera-trap data and information on the success of Blanding’s turtle nests to compare adjacent control and raccoon-removal sites.

Key results

Raccoon detections were more frequent and abundance index values were higher at control sites than at the removal site. However, Blanding’s turtle nest success did not differ between control and removal sites, likely because of differences in nest location and camera proximity.

Conclusions

The efficacy of raccoon removal for Blanding’s turtle conservation may vary with nest habitat characteristics and can benefit from a priori knowledge of nesting areas.

Implications

Mesopredator removal can be beneficial to species of conservation concern, provided it occurs in areas of greatest impact.

浣熊数量指数化和清除：对布兰登海龟筑巢成功率的影响

背景中型食肉动物数量的增加会对受保护物种构成威胁。目的我们试图评估清除浣熊对浣熊数量和布兰丁海龟筑巢成功率的影响。方法我们利用照相机诱捕数据生成的浣熊数量指数和布兰丁氏海龟筑巢成功率的信息，对邻近的对照地点和清除浣熊的地点进行比较。主要结果与移除地点相比，对照地点的浣熊探测频率更高，丰度指数值也更高。然而，布兰丁氏海龟筑巢成功率在对照地点和移除地点之间并无差异，这可能是因为筑巢地点和摄像头距离的不同。结论移除浣熊对保护布兰丁氏海龟的效果可能会随巢穴栖息地特征的不同而变化，并可受益于对巢穴区域的先验知识。意义移除食肉动物对保护受关注的物种是有益的，前提是要在影响最大的区域进行移除。

期刊介绍： Wildlife Research represents an international forum for the publication of research and debate on the ecology, management and conservation of wild animals in natural and modified habitats. The journal combines basic research in wildlife ecology with advances in science-based management practice. Subject areas include: applied ecology; conservation biology; ecosystem management; management of over-abundant, pest and invasive species; global change and wildlife management; diseases and their impacts on wildlife populations; human dimensions of management and conservation; assessing management outcomes; and the implications of wildlife research for policy development. Readers can expect a range of papers covering well-structured field studies, manipulative experiments, and analytical and modelling studies. All articles aim to improve the practice of wildlife management and contribute conceptual advances to our knowledge and understanding of wildlife ecology. Wildlife Research is a vital resource for wildlife scientists, students and managers, applied ecologists, conservation biologists, environmental consultants and NGOs and government policy advisors. Wildlife Research is published with the endorsement of the Commonwealth Scientific and Industrial Research Organisation (CSIRO) and the Australian Academy of Science.
