Study biodiversity in natural protected areas

We investigate the space use and behavior of medium-sized mammals using a long-term camera trap design

The focus is on changes in their ecology caused by the interactions between humans and wildlife (e.g. such as recreation and hunting). We use and optimize existing spatial distribution models. However, the inability of camera traps to identify individuals of species without natural markings, in addition to limits in individual detectability, is a well-known obstacle in faunistic abundance estimation, preventing the use of traditional analytical techniques to quantify population dynamics. Therefore, in CMK, together with DSI, we develop a statistical framework for camera trap data analysis in ecological research. Recently proposed methods provide solutions, but often fail to account for multiple sources of bias and typically focus only on the analysis of a single target species. Moreover, it remains unclear how study protocols affect their performance and to what extent cost-effectiveness differs between study designs. At CMK, we use a statistical framework to analyze data from camera traps. We study mammalian population dynamics in the National Park Hoge Kempen (Belgium) and formulate conservation strategies, using data from a wide range of taxonomic groups. We extend existing methodology into less assumption-driven models, including simulations for single species and communities, and compare their potential, from statistical, practical, and economic perspectives. This will yield improved guidelines for data collectors and analysts, as well as a better understanding of mammalian abundances with the potential for direct implementation in conservation policies. For this research domain CMK collaborates intensively with the fauna division of INBO and DSI-UHasselt.

We study ways to translate knowledge on species in natural protected areas into policy advice

We perform a detailed analysis of space and habitat use; we evaluate the breeding success and survival; we investigate the food availability, in addition to possible food crops, and we analyze the body condition of individuals through blood analyses. The target species and areas are determined in consultation with the client. The effects of the environment on the occurrence of these specific species and the effects of associated management measures on the distribution of these species is statistically processed at three different scale levels. Currently, we have focussed on the nightjar, field and meadow birds, and the wild boar.

Projects

• the Nightjar - A multi-disciplinary approach is used to gain the necessary knowledge in the ecology, microhabitat preference and behaviour of these birds
• WASP Project - In this project we employ a citizen science approach to contribute towards a better understanding of the public perception of various animal groups, and of how this perception is linked to these animals’ traits and their role in society and in ecosystems.
