Mortality of small animals on singletrails in Marianské údolí valley (Brno, Czech Republic)
Homolka, Miloslav; Mikulka, O.; Kamler, J.; Drimaj, J.; Plhal, R.
2021 - English
Singletrail areas became a part of tourist business all over the world. Cycling routes usually go through the natural environment, they are used especially in the summer and therefore are quite evident that small animals are killed on them. The submitted contribution indicates what effects have the traffic on the singletrail on small animals in the deciduous forest environment (Brno, Czech Republic). During singletrail traffic insects and small vertebrates were killed. The number of cadavers of individual species was relatively small on the trails (3800 individuals of insect and 51 of vertebrates one during 3 months on the 11 km of the route) and traffic most probably does not endanger the existence of any animal species at the local population level. Mostly the common species were perished on the trails, but individuals of specially protected and endangered species were also killed there (Calosoma sycophanta, Bombus spp., Anguis fragilis, Bufo bufo) so this fact should not be overlooked and underestimated. For ethical and educational reasons, the construction of new singletrail areas should be preceded by careful research of particular area in order to map the distribution of small animals and choose the route with regard to minimizing mortality, especially endangered species of fauna.

Influence of singletrails on wildlife distribution in the tourist attractive area of Mariánské údolí (Brno)
Drimaj, J.; Mikulka, O.; Kamler, J.; Plhal, R.; Homolka, Miloslav
2021 - English
The growing popularity of active movement in nature in the form of an adrenaline experience is the cause of the great expansion of singletrails. New singletrails are still being built with varying degrees of difficulty, and the density is thickening across the entire Czech Republic. This form of leisure time use is closely linked to the forest environment and the animals that occur in it. The cyclist usually moves very quickly along a narrow path through the forest and it is a question of how his disturbance will affect large mammals around the singletrails. For monitoring purposes, we selected four study areas (two with singletrails and two without singletrails) with the presence/absence of hiking paths where we observed the long-term influence of singletrails on the distribution and behaviour of common species of large mammals through animal marks. The results showed that where the roe deer was not disturbed, a balanced proportion of beds (places where the roe deer rested) and marking places (places that the roe deer marked) was recorded. However, in areas with disturbance in the form of tourists, far fewer beds were found than marking places. The presence of singletrails did not play a role in this.

Cycling and its influence on animal behavior
Mikulka, O.; Drimaj, J.; Plhal, R.; Homolka, Miloslav; Kamler, J.
2021 - English
In terms of impact on society, cycling brings a number of benefits, including the impact on mental and physical health, reducing emissions and the economy of target areas. With the growing popularity of this sport, it also brings negative effects, especially on natural ecosystems. Few studies point to the influence of wildlife behavior. At the same time, the results are important for use in the construction of cycle paths in nature and especially protected areas. The study deals with the influence of cycling of single-track cycling trails in the forest environment, on the spatial behavior of wildlife in a suburban locality, which is very intensively visited by humans. The study partially demonstrated the interfering effect on wildlife, which was detected through the distribution of roe deer (Capreolus capreolus) and wild boar (Sus scrofa) signs. However, the nature of the environment, which affects the intensity of interference, plays an important role. The intensity of trail traffic had a small effect. The results of the study can serve as a basis for designing cycle paths for the future. Keywords: Hiking; Nature conservation; Recreation; Wildlife Fulltext is available at external website.

Settlement of the landscape with European beaver (Castor fiber) in relation to anthropogenic influences
Mikulka, O.; Patočka, Z.; Drimaj, J.; Kamler, J.; Plhal, R.; Homolka, Miloslav
2019 - English
The European beaver (Castor fiber) is a protected species in the Czech Republic that has spread to the whole of Moravia. Now, it is a common species whose competitor is only human. The aim of this study was to evaluate the impact of human activity, especially tourism or transport, on the settlement of the landscape by the European Beaver. The area of the protected landscape area Litovelske Pomoravi was chosen to evaluate the settlement of the landscape by the beaver, where the beaver forms a stable population for a long time and the frequented cycling routes, hiking trails and the area are frequently visited by natural floodplain forests. The beaver settlement data were collected by means of the winter monitoring of residential stamps using the GPS system in 2017. Data on the location of cycle routes, hiking trails, human settlements and infrastructure were obtained from available GIS layers. Settlement of European beaver was evaluated in relation to the distance and intensity of interference by tourist activities, traffic or buildings. There were 200 km of watercourses in the monitored area. The inhabited beaver was 39% of the length. The beaver avoided human settlements, preferring the natural environment. The influence of tourism on the beaver settlement has not been proven.

Halačka, Karel; Adámek, Zdeněk; Jurajda, Pavel; Mareš, J.; Kopp, R.; Grmela, J.
2019 - Czech
Cílem metodiky je poskytnout správcům a uživatelům malých vodárenských nádrží typu Hamry na základě současné úrovně poznatků a realizovaného výzkumu při řešení projektu metodickou pomůcku pro optimalizace monitoringu kvality vody v těchto nádržích. Dále pak návrh metodiky monitoringu rybího společenstva a optimalizaci zásahů pro omezení nežádoucích druhů ryb a posílení stavu vhodných rybích druhů pro dosažení topdown efektu a pro udržení nebo zlepšení kvality vody v těchto vodárenských nádržích. V předložené metodice jsou shrnuty poznatky dosažené při sledování a hodnocení vybraných parametrů kvality vody, planktonních a rybích společenstev na vodárenských nádržích Hamry za poslední roky. Zároveň obsahuje vyhodnocení aplikovaných zásahů, zaměřených zejména na rybí obsádku. Jednalo se o odlovy nežádoucích druhů ryb a vysazování ryb dravých se snahou o optimalizaci složení rybího společenstva pro pozitivní ovlivnění kvality vody v nádrži běžné označované jako účelová rybí obsádka. Metodika zahrnuje doporučení pro monitoring kvality vody v nádrži, a to včetně monitoringu planktonního společenstva, monitoring ryb a doporučené manipulační zásahy v rámci rybí obsádky. Metodika poskytuje pokyny a informace pro optimalizaci monitoringu a zásahů pro malé vodárenské nádrže typu Hamry. The aim of the methodology is to provide managers and users of small water reservoirs Hamry type with methodological tools for optimization of the water quality monitoring based on the current level of knowledge and research. Furthermore, provides a design of a methodology for fish community monitoring and optimization of treatments to reduce unwanted fish species and strengthen the status of suitable fish species with the aim of achieving the topdown effect and maintaining or improving water quality in these water reservoirs. The presented methodology summarizes the findings obtained during the monitoring and evaluation of selected parameters of water quality, planktonic and fish communities in water supply reservoirs Hamry in recent years. It also contains an evaluation of applied treatments, focused mainly on fish stock. Unwanted fish species were caught and the predatory fish were stocked with the aim of optimizing the fish community composition and positively influencing the quality of the water in the reservoirs. The methodology contains recommendations for monitoring of the water quality in the reservoir, including monitoring of planktonic communities, monitoring of fish and recommended manipulation with fish stock. The methodology provides guidance and information for optimization of monitoring and treatments for small water supply reservoirs of the Hamry type.
