The fact that there are so few <strong>bear</strong>s in Latvia and most of them belong to one sex are<br />
probably the main limiting factors that does not allow for an optimisti prognosis for the <strong>bear</strong><br />
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 />
relevant are those factors that prevent <strong>bear</strong>s from staying in Latvia after coming here from<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 />
Latvia as a transport transit country will develop its transport infrastructure significantly. It is<br />
difficult to give a clear assessment of the impact of recreation and tourism development. Tourism<br />
