Wildlife population changes across eastern europe after the collapse of socialism

Abstract

When political regimes fall, economic conditions change and wildlife protection can be undermined. Eastern European countries experienced turmoil following the collapse of socialism in the early 1990s, raising the question of how wildlife was affected. We show that the aftermath of the collapse changed the population growth rates of various wildlife taxa. We analyzed populations of moose (Alces alces), wild boar (Sus scrofa), red deer (Cervus elaphus), roe deer (Capreolus capreolus), brown bear (Ursus arctos), Eurasian lynx (Lynx lynx), and gray wolf (Canis lupus) in nine countries. Population growth rates changed in 32 out of 49 time series. In the countries that reformed slowly, many species exhibited rapid population declines, and population growth rates changed in 83% of the time series. In contrast, in countries with fast post- socialism reforms, many populations increased rapidly, and growth rates changed in only 48% of time series. Our results suggest that the direction and frequency of the changes were associated with socioeconomic conditions, and that wildlife populations can be greatly affected by socioeconomic upheavals.
