Possibilities of evaluation and comparison of data obtained from control and comparison plots (CCP) in relation to damages caused by game to forest
Šafránek, Zbyněk ; Matala, Juho
The article deals with the possibilities of evaluation and interpretation of data on game damages in forests which is obtained and collected from control and comparison plots (CCP). Obligation to record the data in young forest stands on the base of control and comparison plots is directed by Act No. 289/1995 Coll., respectively Ministry of Agriculture Decree No. 101/1996 Sb. Each forest owner who has more than 50 hectars of forest has obligation to establish control and comparison plots.

Possibilities of detection of amount game damages by grazing in artifically established forest stands
Šafránek, Zbyněk
Procedure for determination of input data in areas damaged by game grazing for the purpose of calculating the amount of damage caused by wild game according to Decree no. 55/1999 Coll. is not standardized. The article deals with the possibility of obtaining such input data in a schematic-based forest stands, particularly row plantations. The aim of this paper is to compare the reliability of input data obtained on the basis of counting all individuals on the injured area compared with the counting on the sampling plots - rows. This paper is part of the author's doctoral dissertation titled Standardization of expert detection amount of game damages to the forests.

Šafránek, Zbyněk
This article deals with the calculation of browsing damages caused by game on young forest stands in the Ore Mountains (Forestry Administration Klášterec nad Ohří). In selected stands were counted all individuals of tree species with the distribution to the damaged and undamaged. This method of determining the percentage of damaged trees is the most precise, but excessively time-consuming. For comparison of the results was used also selection method - a circular plots. The aim of this paper is to determine the accuracy of the sampling method compared with the simple counting of damaged individuals.
