Methodology to rodent bark damage assessment on forest regeneration
No full textThis methodology provides us with instructions, how to estimate extent of bark damage by gnawing caused by rodents on forest plantings based on a simple criterions. Data obtained may be used for objective assessment of rodent origin tree damage extent and its total value calculation. Exact data on tree damage can be used as a back coupling for damage prevention effectiveness. Relation between the rodent damage prevention costs and damaged area replanting costs may be retrospectively considered

No full textMortality of small animals on singletrails in Marianské údolí valley (Brno, Czech Republic)
No full textSingletrail 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
Methodology to rodent species density monitoring in forest environment
No full textThis methodology provides us with instruction how to monitor rodent densities in forest environment and is concentrated on the species causing damage to broad-leaved forest plantings. Principle presumption for effective plantings protection control is to know rodent’s population density. Basic ecological informations about the target species are also included. This methodology book contribute to better understanding of young tree damage origin in broader connections and contribute to more effective input on damage prevention. Methodology is addressed above all to forest practices workers
