Zhodnocení distribuce trusu prasete divokého v lesním prostředí jako podkladu k odhadu jeho početnosti
Drimaj, Jakub
In study area near the town of Jihlava, formed by two forest hunting grounds, was realized a survey of distribution of droppings of wild boar (Sus scrofa L.) in order to verify the validity and improvement of dung census methods to estimate wild boars density in the forest environment. Counting of droppings was performed after the fall of the snow cover (before the growth of vegetation), on uniformly spaced lines (in strip transects), set by using geoinformation system and GPS devices. Each faecal pellet group (FPG) was geographically focused (GPS coordinates) and comprehensive database of 3 442 FPG was analysed over the digitized map data of Lesy ČR, s. p. (LHP). The average FPG density in the forest environment was 143,4 FPG.ha-1 and wild boar abundance was estimated at 19 individuals.km-2.
