Methods

For the analysis of bird population biodiversity we used data of quantitative survey routes during the nesting period according to the Ravkin S. procedure (1967). Periods of registration works - May-June 1985-1997. Three survey routes are located in the Ilmen Nature Reserve (Subprovince of eastern ranges and dissected foothills). The first survey route 7 km long passes through pine-birch forests. The composition of the forest stand: 7P3B 7P3B + As 6P4B; the height of the main tier from 23 to 26 m; age - 100-140 years B - 70-90 years As - 70 years; bonitet - II and III classes. Occurring forest types are represented by forb-grass forb-grass-fern herb-fern and forb pine forests. The sparse undergrowth with broom. The second route 4 km long is located in the pine forests. The composition of the forest stand: 10P 10P + B 9P1B; the height of the main tier from 27 to 29 m; age ? P - 110-140 years B - 80-90 years; bonitet - I and II classes. The most common here: berries blueberry-bilberry-green moss herb- bilberry and herb-fern pine forests. The sparse and medium undergrowth with broom and wild rose. The third route 3 km long is located in the birch forests. The composition of the forest stand: 10B 10B + P 10B + P + As 9B1P; the height of the main tier from 23 to 28 m; age: B - 80 years; bonitet - I and II classes. Occurring forest types are represented by forb forb-grass-fern and herb-fern birch forests. The undergrowth is with sparse and medium density with broom wild rose and raspberry.
