The effects of non-native plantation established after clear-cutting were studied in Dongling Mountain region, Northern China. Pitfall catches of Carabus beetles from a non-native larch plantation were compared with those from two native forests, an oak forest and a mixed broad-leaved forest. More individuals were captured from the mixed broad-leaved forest and the larch plantation than from the oak forest. For the threemost abundant species in this area, C. crassesculptus peaked in abundance in the mixed broad-leaved forest; C. manifestus peaked in the larch plantation, and C. sculptipennis in the oak forest. Measured by PcoAusing Bray-Curtis index of dissimilarity, species composition of the larch plantation was different from the two native forests, but overlapped remarkably with them. All the three abundant species showed a similar positive relationship between local distribution and abundance. Captures of abundant species were clumped within the forest, but the extent of aggregation among forests was different. Monthly catches of total Carabus, and C. crassesculptus alone, peaked in June–August in all the three forests, but C. manifestus peaked in June and again in August. Our results suggest that the planting of non-native larch does not have a detrimental effect on Carabus assemblages in general, but it changes the spatial distribution and abundance compared to the native forests.

to date, the main parameters for assessing the state of the forest are the average age, height, diameter, and completeness of the main forest-forming rocks, expressed in meters, fractions of a meter, or cubic meters. At the same time, on the same test areas, other measurement measures are used for soil research: milligrams, grams, percentages, moles, etc. Naturally, it is impossible to combine these indicators when characterizing the forest environment. To do this, first of all, you should choose a single system of measures, parameters and indicators that combine the biogenic and lithogenic parts of the landscape. Knowing that their interaction is based on energy and mass exchange, we suggest using measures common to both subsystems. The initial indicators for quantifying the oxygen-producing and carbon-depositing functions, as well as the energy accumulated in the primary products of forest ecosystems, are the elements of biological productivity expressed in weight units. The object of research – Voronezh upland oak forest, with a total area of more than 7 thousand hectares, is the Central organizing element of the entire urban ecosystem of Voronezh. The tree stand is represented by coniferous crops along the left Bank of the floodplain terraces, as well as broad-leaved forest plantations spread on the riverine slopes of the watershed.

The tropical seasonal rainy evergreen broad-leaved forest vegetation of the Cucphoung National Park has been classified and the distribution of plant communities has been shown on the map using the relations of vegetation to geology, geomorphology and pedology. The method of vegetation mapping includes: 1) the identifying of vegetation types in the remote-sensed materials (aerial photographs and satellite images); 2) field work to compile the interpretation keys and to characterize all the communities of a study area; 3) compilation of the final vegetation map using the combined information. In the classification presented a number of different level vegetation units have been identified: formation classes (3), formation sub-classes (3), formation groups (3), formations (4), subformations (10) and communities (19). Communities have been taken as mapping units. So in the vegetation map of the National Park 19 vegetation categories has been shown altogether, among them 13 are natural primary communities, and 6 are the secondary, anthropogenic ones. The secondary succession goes through 3 main stages: grassland herbaceous xerophytic vegetation, xerophytic scrub, dense forest.
