Involving Stakeholders in Bear Monitoring

Introduction

Monitoring wildlife is crucial for conservation and management, as it provides valuable information on population trends and distribution. Efficient monitoring is costly in terms of time and resources, including personnel. These costs increase in large, remote regions that are difficult to reach, limiting monitoring activities, especially when they extend over national borders.

The Dinaric Mountains are a rugged and extensive mountain range where brown bears roam vast transboundary areas, including remote mountainous regions and dense forests. Additionally, the area’s political fragmentation makes cross-border coordination difficult. To ensure meaningful and comparable data, effective monitoring in such regions requires international cooperation and harmonised methodologies in addition to a considerable number of trained personnel.

Collaborative monitoring through citizen science offers a powerful solution. By engaging local stakeholders like hunters and foresters, who regularly work in bear habitats, monitoring challenges become opportunities. These local experts serve as citizen scientists, improving data collection whilst fostering shared responsibility for conservation. The EU LIFE-funded DINALP project exemplifies this approach in Slovenia and Croatia, where hunters, foresters, and volunteers collect bear scat samples for genetic analysis. Sustained engagement is maintained through personal interaction and personalised feedback, complemented by annual population status reports.

Key actions

Setting up a large volunteer network, primarily comprising hunters and foresters.

Design, production and distribution of DNA-sample kits to collect bear scat, including detailed instructions, sampling tubes, a data-entry form and pre-addressed and stamped envelopes.

Establishment of individual e-mail communication to motivate volunteers with regular updates and provide feedback, including tracking information on bears linked to their samples.

Sampling the entire brown bear range in Slovenia and Croatia, covering over 20,000 km² and analyses of the samples using advanced genetic methods.

Results

The project delivered the first precise estimate of brown bear population size and sex structure in the north-western Dinaric Mountains, providing Croatia with its first reliable data and establishing a key baseline for future conservation. Over 4,600 samples were collected by more than 2,500 participants, mainly hunters and foresters, far exceeding targets and fostering strong stakeholder engagement. The approach has strengthened science-based management in both Slovenia and Croatia, with follow-up sampling in 2023 ensuring ongoing monitoring. Slovenian results were published in April 2025, while Croatian results are expected by early 2026.

Financing

The 2015 project received funding from the DINALP EU LIFE programme and co-funding from both countries’ relevant ministries. Monitoring has since become a regular practice supported by national funding, with the 2023 survey financed by each country’s respective ministry.
