transboundary monitoring at the edge of an expanding

brown bear population Experiences from LIFE DINALP BEAR project

Brown bear

distribution

Europe at night (NASA/NOAA)

• 5 years (Julij 2014 – Junij 2019), 5.998.048€

• 4 countries (Slovenia, Croatia, Italy, Austria)

• 9 partners (lead beneficiary Slovenia Forest Service

PROJECT AREA

Core Area – high population

density, (relatively) low conflicts.

Expansion area – low population density, high conflicts.

Main Goals

• Establishment of transboundary management and conservation of

bears in the northern Dinaric Mountains and the Alps.

• Decrease of human – bear conflicts and promotion of coexistence.

• Support for natural expansion of the brown bear into the Alps.

First goal on the path to collaboration: GET PEOPLE TO START

TALKING! • Common Guidelines for Population-level Brown Bear Management

in NW Dinaric Mountains and the Alps (involving all key stakholders

in the process).

• Commitments of governments of participating countries to integrate

the results into national legislation.

• Wider collaboration – other Alpine Convention Countries (process

endorsed by the WISO platform), Bosnia.

It‘s not enough that managers from different

countries start talking to each other….

…they need to have

something to talk about.

“Counting fish is just like counting trees…

…except that they are invisible and keep moving.“

John Shepherd

Between 500 and 1000 participants.

1052 samples, 354 different bears „captured“.

2007 – intensive study in Slovenia (UL, SFS, SHA)

*The main result for bear management:

we stopped arguing about the population size...

*there are other benefits

… for a while.

2015 - estimates of population size, sex structure and

population range using non-invasive genetic sampling

High-intensity sampling

1,900,000 ha

19,000 km2

~ 6000 km2 SLO

~ 13,000 km2 HR

Lower intensity, long-term opportunistic sampling.

„This is nice.

I wish to participate!“

Personal – Level Involvement of Volunteers

GOAL!

Get individual people to directly participate!

Engage critical stakeholders,

mainly hunters and foresters

Personal DNA sampling kit

„Yay! I found a bear scat!“

Integration of bear habitat connectivity and suitability

into spatial planning

• Understanding habitat connectivity for bears in the project area.

• Production of „Environmental Impact Assesment Guidelines“ to

include spatial needs of bears in spatial planning.

Hopefully, a start of population-level monitoring and management…

…but at the end of the day, there needs to be a

will to collaborate for this to work in the long term.
