- Abstract
Organic substrates are distinctive and important resources due to their ability to regulate nutrient cycles and habitats they provide. In this research we test the importance of organic substrates for present distribution of habitats accumulating organic sediment and compare historic (circa 1850) and present land cover maps to characterise the long-term change on these substrates. The results show: 1) areal extent of organic substrates in lowlands is 8552 ha, in highlands 11,465 ha and in mountains 13,374 ha; 2) the area of current mire habitats is 43,801.75 ha, on organic-substrates it is 9555.64 ha (i.e. 21.82% share on all current mire habitats) and mire habitats covers 28.62% of organic sediments, and; 3) the test of losses and gains among land cover units and between organic and non-organic soils show us, that the most remarkable land cover losses on organic soils occurred on grasslands in all altitude categories – to water areas and arable land in Lowlands (< 350 m a.s.l.), to forests in Highlands (from 350 to 750 m a.s.l.) and Mountains (> 750 m a.s.l.). Although organic sediments are sparse in lowlands, they were found to be very important for the present distribution of mire habitats.
