The authors discuss the methods and results of mapping the forest susceptibility to wildfires and windthrows on the example of the Ural region. We used the previously published database of fire-and wind-related forest damages in the Ural region for 2000–2016 as input data. The method of mapping is based on the analysis of the relationships of fire- and wind-damaged area with forest species composition, landscape and climatic variables, and with some indicators of anthropogenic development of the territory. The predominant forest species make the main factor determining the exposure to wildfires and windthrows. So, the calculations were performed separately for forests with various predominant species. As a result, the maps of forest susceptibility to wildfires and windthrows were created for the entire territory of the Ural, Perm region and separately for the Krasnovishersk district of the mentioned region. The obtained estimates can be used both in forestry planning and improving the monitoring of wildfires and windthrows.

AbstractForest carnivores are threatened globally by logging and forest fragmentation yet we know relatively little about how such change affects predator populations. This is especially true in Madagascar, where carnivores have not been extensively studied. To understand better the effects of logging and fragmentation on Malagasy carnivores we evaluated species composition, density of fossa Cryptoprocta ferox and Malagasy civet Fossa fossana, and carnivore occupancy in central-eastern Madagascar. We photographically-sampled carnivores in two contiguous (primary and selectively-logged) and two fragmented rainforests (fragments <2.5 and >15 km from intact forest). Species composition varied, with more native carnivores in the contiguous than fragmented rainforests. F. fossana was absent from fragmented rainforests and at a lower density in selectively-logged than in primary rainforest (mean 1.38±SE 0.22 and 3.19±SE 0.55 individuals km−2, respectively). C. ferox was detected in fragments <2.5 km from forest and had similar densities in primary and selectively-logged forests (0.12±SE 0.05 and 0.09±SE 0.04 adults km−2, respectively) but was absent in fragments >15 km from forest. We identified only two protected areas in Madagascar that may maintain >300 adult C. ferox. Occupancy of broad-striped mongoose Galidictis fasciata was positively related to fragment size whereas occupancy of ring-tailed mongoose Galidia elegans elegans was negatively associated with increasing exotic wild cat (Felis spp.) activity at a camera site. Degraded rainforest fragments are difficult environments for Malagasy carnivores to occupy; there is a need to prioritize the reconnection and maintenance of contiguous forest tracts.

Current state of forest fund of Vyzhivka River basin was described and evaluated. Statistics and dynamics of forest reserves and composition of tree species and age structure of forests were analyzed. Groups of forests by economic importance and the main types of environmental management within forest fund of studied area were allocated. Both negative and positive sides of it were shown. Key words: forest fund, forest species composition, age structure of forests, logging, reforestation.

Sixteen mangrove species from 10 families, including four associate species, were recorded in 4 study plots along the riverbanks of Balok river, Kuantan and Pahang. Rhizophora   apiculata and Xylocarpus granatum appeared in all plots.  R. apiculata shows the highest density (819 per ha) followed by R. mucronata (775 per ha). Highest species diversity was recorded in the order of plots located on downstream to the river mouth, based on the Shannon-Weiner Diversity Index.Key words: Mangrove; flora; ecology; regeneration; dominance;  diversity; Pahang.doi: 10.3126/eco.v13i0.1624Ecoprint (An International Journal of Ecology) Vol. 13, No. 1, 2006 Page: 23-28
