The article provides data on the assessment of the state of broad-leaved forest crops created during the reconstruction of low-value forest stands in the forest fund. The effectiveness of various methods of reconstruction of measures depending on the share of broad-leaved species in the composition of forest crops is analyzed. It was found that during the period 2006–2018 reconstruction was carried out on an area of 3628 hectares in the Republic of Belarus using corridor (69 %), curtin-group (22 %) and continuous (9 %) methods. It is shown that the average survival rate of forest crops in the continuous reconstruction method was 84, corridor — 71 %, and preservation, respectively, — 61 and 63 %. The sub-topological forest crops created during the curtin-group reconstruction had an unsatisfactory condition (average survival and preservation — 40 %). It is recommended when creating broadleaf forest crops during the reconstruction of low-value forest stands to take into account their age, composition, forest growing conditions, as well as the biogroup placement of plantings, which ensures faster closing of crops in rows, and contributes to their favorable growth and formation, and to create an optimal width of corridors 4...6 meters, which will ensure uniform and sufficient distribution of light in forest crops.

Abstract Broad-leaved trees play an important role in supporting epiphyte richness in deciduous forests. In this study we tested which broad-leaved forest stands in terms of tree composition best predicted biodiversity in regard to bryophyte species number and their functional traits. The bryoflora was surveyed in 70 stands differing in dominant broad-leaved tree species. One circular plot with diameter 30 meters was established in each stand situated in different parts of Latvia. Fifty-three of the plots were located in stands identified as protected habitats of the European Union. In total, 82 bryophyte species were recorded. At plot level the total number of species ranged between 6 and 38 species. Using principal component analysis (PCA), the ordination axes explained 41% of the variation in composition of bryophytes. The PCA axes were related to tree species composition. The presence of broad-leaved trees, especially ash, lime, and oak, was connected with higher species richness. Generalised linear models confirmed that epiphyte richness, both at the total and indicator species levels, was higher in ash stands. From the functional traits, all expected life-strategy and life-form categories were recorded. The most represented life-forms were smooth mats, tall turfs, and rough mats, while the dominant life-strategy was perennial stayers, followed by competitive perennials and long-lived shuttles. Functional trait richness was highest in Fraxinus excelsior, Tilia cordata, and Quercus robur forest stands.

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.
