    Attempts to estimate the allowable maximum population density is well known in the history of game management in Latvia. Relatively permanent environmental features (e. g. landscape and forest structure) have been used for the assessment of carrying capacity of hunting grounds. Amount of the available winter feed was considered as a limiting factor for major game species in each landscape unit and forest type. While focusing on the actual abundance of feed, many other factors, including mutual interaction among species and populations, were overlooked.

    The aim of this paper is to analyze the structure of forest landscape and its impact on biodiversity in the Bauska District, Latvia. The database of the State Forest Service and field research from 1994 to 2004 were used. Diversity and protection of the current forest ecosystems were described using different forest classification methods. The structure of tree species and their age was analyzed. Analysis indicated a decrease of oak forests by 3.5% of their native vegetation area and a high proportion of drained forests, as well as a disproportional age structure of forest ecosystems.
