Description of Isognomostoma isognomostomos habitat

In Latvia, I. isognomostomos inhabit forests of ravines with at an average altitude of 188.2 m above sea level. For example, in Poland, it is found in Białowieża Forest within 134–202 m ( Cameron & Pokryszko 2004). In the main area of distribution, snail inhabits mainly high-altitude regions (300 – 1800 m) ( Shileiko 1978, Kerney et al. 1983, Pfleger 1984, 1995, Alexandrowicz & Alexandrowicz 2006, Maltz 2011). Although I. isognomostomos is montane-Carpathian species ( Kerney et al. 1983), it also may be found in lowland where habitats have pronounced relief. The mask snail in the main area of distribution is found mainly in beech forests and oak-hornbeam forests ( Kerney et al. 1983, Pfleger 1984, Falkner et al. 2001, Beckmann & Kobialka 2007). In Latvia, I. isognomostomos inhabit 60–100 years old forests and the forest stands is of natural origin. There are broad-leaved forests of ravines where the most abundant tree species are elm, maple and lime, whereas ash, oak, aspen and other deciduous tree species occur rarely ( Table 2). Spruce, pine and birch represent mixed coniferous forests.
