Outlook on climate change adaptation

Biodiversity The Carpathians are widely recognized as an important biodiversity hotspot for mountain species in Europe (Stewart, 2009), including rich native flora and many rare animals. About one-third of all European vascular plants, representing 4000 species, grow in the Carpathian area. The biodiversity of invertebrates and fungi in the woods is especially remarkable. Different bird species, including migrating birds and owls have been registered in the area. Red deer, roe deer, chamois, brown hare, otter, bats and many other species are living in the area. The region is also home to one of the biggest populations of large carnivores in Europe, such as wolf, lynx, wildcat and brown bear. Due to its diverse landscape, the Carpathian Mountains host a vast variety of natural and semi-natural ecosystems, including forests, grasslands, pastures and wetlands. The changes in CO 2 concentrations as well as temperature and precipitation regimes will

affect the physiological processes of fauna and flora (UN Environment, 2014). There are few studies on the effects of climate change on mountain ecosystems, especially in the Carpathians (Bálint et al., 2011). Nevertheless, some of the research of other mountain areas can be applied to the Carpathians. The results show that the expected climate change will have a noticeable impact on the biodiversity (Thullier, 2007; Mooney et al., 2008). The displacement of natural boundaries and the loss of natural ecosystems, including the corridors for migration of rare and endemic species, might be the consequences. Climate change will probably lead to an upslope climbing of the tree line, which will affect the species composition of grassland ecosystems. As grasslands often host rarer and more fragile species than bushes and forests, this would lead to biodiversity losses (Pellissier et al., 2012; Niedrist et al., 2009). Ecosystems on limy soil are more species-rich and more sensitive than vegetation on other substrates (Werners et al., 2014b). Other species try to adapt by changing their phenology. Higher temperatures and less water during the vegetation period will threaten wetland ecosystems. Peatlands, small streams, wells and floodplains are especially at risk because they have a low drought resilience (Werners et al., 2014b). Wetland loss would also reduce habitats for the many dependent plants and animals and lead to habitat fragmentation that could threaten migration of animals on a regional scale (UN Environment, 2014). Furthermore, it will influence the carbon cycle, the emissions and uptake of greenhouse gases. Warmer and shorter winters will also affect animal hibernation. As this period will probably get shorter, the food demand of these species will rise. Furthermore, species that are currently living in protected areas could have to migrate or adapt to survive.
