Briefings

Recent data indicate Finland's white-tailed eagle population has recovered significantly since legal protection and environmental improvements began in the 1990s. The species, once rare in Europe, shows marked increases across multiple regions, with specific population growth rates documented for the last decade. However, long-term trends and the exact magnitude of recovery remain uncertain due to limited historical baseline data.

Key points

• The white-tailed eagle population in Finland has increased substantially since the 1990s due to legal protection and cleaner environments.
• Historical baseline data is insufficient to calculate precise long-term recovery rates or confirm the current population size.

Context

Finland implemented strict conservation measures for the white-tailed eagle in the 1990s, leading to observed population growth. This recovery is significant as it represents a successful ecological restoration effort in a region previously threatened by persecution and pollution.

Limitations

Evidence is limited to recent observations and lacks comprehensive historical baseline data. Long-term trends and exact population figures remain uncertain due to insufficient historical records.
