Vydry vs automobily - problém aj v mestách: prípadová štúdia Banská Bystrica - Zvolen (stredné Slovensko)

Urban, Peter, 1962- Vydry vs automobily - problém aj v mestách: prípadová štúdia Banská Bystrica - Zvolen (stredné Slovensko) = Otters vs cars - problem also in cities: a case study Banská Bystrica - Zvolen (Central Slovakia) / Peter Urban ... [et al.]. -- In the last two decades an increase and a colonizing tendency of the otter population in the Hron River catchment have been registered. The increase was most pronounced in the central part of the catchment and probably is related with the improvement of surface water quality in the 1980s and 1990s. This species also uses the urbanized environment of cities. We recorded 11 killed otters during 5 years (2013 – 2017) on the roads in settlements between Banská Bystrica and Zvolen (5 cases in Zvolen, 3 in Banská Bystrica, 2 in Sliač a 1 in Vlkanová). In two cases otters were killed on the speed communication ( R1 in Banská Bystrica-Radvaň), in five cases on the first class roads (4 on I / 16 and 1 on I / 69), in two cases on third class roads (Sliač, Vlkanová) and in two cases (Banská Bystrica-Kremnička and Zvolen-Harajch) on local communications. Spatial representation of secondary landscape structure elements – artificial areas in the 1 000 m buffer circles makes up from 15,54 % (Banská Bystrica-Kremnička) to 78.28 % (Zvolen, Harajch), average is 45,10 %. Spatial representation of built-up-areas in the 1 000 m buffer circles was similarly the lowest in Banská Bystrica-Kremnička (0,18 %) and the highest in Zvolen, Harajch (12,64 %), with an average of 5,38 %. Distance of places of death from the Hron river in the 1 000 m buffer circles were from 30 m (Banská Bystrica-Radvaň) to1 220 m (Sliač, near railway crossing), average 241,4 m. This issue needs to be monitored and solved.
