The provided habitat of many services from natural capital is important. But because most ecosystem services tools qualitatively evaluated biodiversity or habitat quality, this study quantitatively analyzed those aspects using the species distribution model (MaxEnt). This study used location point data of the goat(Naemorhedus caudatus), marten(Martes flavigula), leopard cat(Prionailurus bengalensis), flying squirrel(Pteromys volans aluco) and otter(Lutra lutra) from the 3rd National Ecosystem Survey.Input data utilized DEM, landcover classification maps, Forest-types map and digital topographic maps. This study generated the MaxEnt model, randomly setting 70% of the presences as training data, with the remaining 30% used as test data, and ran five cross-validated replicates for each model.The threshold indicating maximum training sensitivity plus specificity was considered as a more robust approach, so this study used it to conduct the distribution into presence(1)-absence(0)

“…The flying squirrels seem to be quite sensitive to habitat loss (Selonen et al 2001) and fragmentation effects (Mönkkönen et al 1997;Reunanen et al 2002) and they generally avoid crossing open areas wider than 100 m . In several studies, the flying squirrels have been shown to prefer larger habitat patches over small ones, patches with higher volumes of deciduous trees, and patches that are close to the other suitable patches (Hurme et al 2007;Reunanen et al 2002;Selonen and Hanski 2004). Because of the anthropogenic obstructions (roads, clear cuts, etc.…”

Siberian flying squirrel (Pteromys volans) has declined in Finland and it is considered an endangered species. We studied microsatellite variation in four flying squirrel populations in a fragmented landscape in Finland to determine the amount of gene flow and genetic diversity in the populations. Demographic data from these areas suggest that the populations are declining. All the populations are significantly differentiated (F ST =0.23). The most notable result is the high degree of differentiation between two adjacent populations (F ST =0.11) and low genetic variability (number of alleles 3.0) in one of the populations. These findings suggest problems in dispersal and possible fragmentation effects in the landscape where only 10-20% of habitat favorable for the flying squirrel is left. Conservation ensuring dispersal should be urgently considered. Future studies should concentrate on the modeling of the population viability and on the effects of inbreeding in these small populations.

“…3). Nest boxes are useful for capturing flying squirrel species (Selonen & Hanski 2004, Taulman & Smith 2004, Lampila et al 2009). However, there has hitherto been no research into the efficient placement of nest boxes for flying squirrels, despite their low nesting ratios (Suzuki et al 2008, Reynolds et al 2009).…”

To improve the effectiveness of research into the Siberian flying squirrel Pteromys volans, we investigated the optimal placement of nest boxes. Of the 96 boxes which we installed under various conditions at 10 sites, 47 were occupied by Siberian flying squirrels between spring and autumn. Nest-box height was positively correlated with box occupation; 90% of boxes installed at 2-2.8 m height were used. Cavity density was negatively correlated with occupation, with boxes more frequently used in forests with , 2 cavities/ha. Research in Siberian flying squirrels can thus be made more efficient if nest boxes are installed at a height of 2-2.8 m in forests with , 2 cavities/ha, and by doing observations between spring and autumn.
