population in Latvia. Such a small isolated population of mainly males would be doomed to go<br />

extinct without any drastic re-introduction efforts. However, considering that Latvia is on the<br />

periphery of the Baltic <strong>bear</strong> popualtion of almost 7000 individuals (Linnell et al. 2008) most<br />

elsewhere. Intensive forestry, hunting, transport and building infrastructure are common factors<br />

that threaten the existing <strong>bear</strong> populations in Europe and there is no doubt that these factors will<br />

hinder <strong>bear</strong> population’s restoration in Latvia as well. Particularly worrying is the perspective that<br />
