The notable variability of wildlife and high degree of biological diversity at the species, genetic and ecosystem levels (Bosnia and Herzegovina is among the top five countries in Europe in respect of biodiversity) is a result of this ecological heterogeneity of space, geomorphologic and hydrological diversity, and climate diversity. There are 1,859 species of 217 genera within the group of cyanophyta and algae. On average, 74 per cent of fungi species on the International Union for the Conservation of Nature (IUCN) Red List for Europe can be found in Bosnia and Herzegovina forest ecosystems.
