BACKGROUND & MAIN GOAL OF THE PROJECT:
The project targets at facilitating long-term conservation of wolves, their prey base and their habitats in Slovenia, and
their co-existence with humans.

1. ELABORATION OF THE WOLF POPULATION ACTION PLAN
- 5 facilitated workshops for the development of the action plan
- Open process – invited all interest groups
- Transboundary component – wolf experts and decision-makers from Croatia also participated

2. Examination and analyses of dead wolves
3. Conservation status – non-invasive genetics
4. GPS – GSM telemetry

The method was and will be used to obtain data on territorial packs/pairs and reproduction events - litters.
3. 1 Howling tests
![Page 8: CONSERVATION AND SURVEILLANCE OF CONSERVATION STATUS … · conservation and surveillance of conservation status of wolf (canis lupus) population in slovenia](https://reader031.vdocuments.net/reader031/viewer/2022021900/5b5f477e7f8b9a057e8dc7f2/html5/thumbnails/8.jpg)

• obtain data on wolf distribution
• data on distribution of packs
• winter pack sizes
• characteristics of wolves‘ movements
• non-invasive genetic samples
• (analyses of prey remains)
3. 2 Snowtracking

2. Pack social structure + dynamics, territories.
3. Damage assesment – who dunnit?
4. Wolf-dog interactions.
5. Population genetics.

(poaching or background mortality)

The idea…
• To harness the power of Internet and public interest for wolves for collecting monitoring data.
• To facilitate data sharing and exchange between experts.
• To disseminate information about wolf presence to the interested public.
