| Summary: | The study of the small mammal communities state in the city’s forest parks and park and in the forest, depending on changes in phytocenoses under the influence of recreation, was carried out. These studies have shown that the lower layers of phytocenoses of the forest communities belonging to pine stand characteristic of the South taiga district of the Trans-Urals foothill forest province (Kolesnikov et al., 1973) have been noticeably changed of the urban area. First of all, we observed a low renewable capacity of the main forest-forming species of the sites and the appearance of new species in the undergrowth, which are not important for forest-forming processes, but are signs of transformation of the lower layers of phytocenosis. The degree of regression digression in all urban sites was medium or weak. In the control it was very weak or absent. In forest parks and park both the extension of the shrub species composition due to synanthropic species and the increase in their number are of greater importance. The undergrowth in them is represented by raspberries (Rubus idaeus L.), tatarian honeysuckle (Lonicera tatarica L.), three-lobed viburnum (Viburnum opulus L.), mountain ash (Sorbus aucuparia L.), bird cherry (Prunus padus L.), goat willow (Salix caprea L.), elderberry (Sambucus racemosa L.), round-leaved irga (Amelanchier ovalis Medik.), dogwood (Cotoneaster Medik.), rosehip (Rosa acicularis Lindl.), hawthorn (Crataegus oxyacantha L.). The undergrowth species composition of the control is much poorer than in urban localities: it contains: bird cherry, goat willow, dog rose, green broom (Chamaecytisus ruthenicus (Fisch. ex Wol.) Klask.), mountain ash. The development of undergrowth is an influence on the growing conditions of grass-shrub species and the development of moss cover with the creation of a regime of favorability for some vegetation groups and suppression of others. Although there is a high similarity in the floral composition of the lower tiers between the forest parks, they differ in the ... |
