The impact of equipments of animal passages on their efficiency

Abstract

The paper describes the impact of the individual components of animal passages on the efficiency of their use. Research was conducted with regard to four species of ungulates: elk, deer, roe deer and boar. The analyzed equipment are road lighting, shielding vegetation, rootwood and tree stumps, anti-glare shields, rocks, fencing. The analysis were made on the basis of surveys which were filled by 87 road operators. Own method of surveys answers analysis was developed and it consists of two stages. It was established that road lighting located in the vicinity of a passage negatively affected its use by the analyzed species. Anti-glare shields clearly positively influence on the efficiency of ecology road infrastructure. Shielding vegetation, rootwood and tree stumps, and anti-glare shields positively influenced on the use of animal passages. Other components do not influence on efficiency of animal passages.
