Brown bear recovery in Greece does not increase damage to human property

A new scientific study by ARCTUROS, based on 22 years of official compensation data (1999–2020), offers important insights into human–wildlife coexistence and biodiversity conservation in Europe. Conducted within the framework of the Large Carnivore Connect project, supported by PONT and implemented by ARCTUROS, the research analysed 7,067 verified compensation claims for brown bear damages across Greece.

Key findings at a glance

The study challenges a common assumption in conservation debates: that the recovery of large carnivores inevitably leads to more conflicts with humans.

Main results include:

• Recovery and geographic expansion of the brown bear population did **not** lead to an overall increase in damages
• Compensation claims increased until 2009, then declined and stabilised from 2012 onwards
• Damage levels in recent years remain comparable to those recorded at the beginning of the study period

In total, most recorded damages concerned:

• Livestock (59.4%)
• Apiculture (23%)
• Agriculture (17.6%)

Where and when damages occur

The research highlights that damage is not evenly distributed but follows clear spatial and seasonal patterns.

Key observations:

• Stable or decreasing damage trends in long-established bear areas
• Increasing trends mainly in newly recolonised regions
• Higher conflict risk where prevention measures and coexistence experience are limited

Seasonal patterns were also evident:

• Livestock and crop damages peak in late summer and autumn
• Apiary damages are more frequent in spring and early summer

These predictable patterns indicate that timely and targeted preventive measures can significantly reduce conflicts.

Relevance for biodiversity protection

The findings are particularly relevant to biodiversity policy and large carnivore conservation in human-dominated landscapes such as those of Southern Europe.

They demonstrate that:

• Species recovery does not automatically translate into escalating human–wildlife conflict
• Prevention is more effective than relying solely on compensation
• Awareness, local support, and mitigation measures are crucial in newly recolonised areas

Importantly, the study shows that public perception of increasing conflicts is not always supported by long-term scientific data, even during periods of population recovery.

Supporting coexistence through science-based conservation

Overall, the research reinforces a key conservation message: the successful recovery of the brown bear in Greece is compatible with stable levels of human impact when effective conservation actions and prevention strategies are in place.

This evidence supports science-based biodiversity protection policies and highlights the importance of investing in conflict prevention, community awareness, and targeted management measures to ensure long-term coexistence between people and large carnivores.
