Nine-year bird community development on Radovesická spoil heap: impacts of restoration approach and vegetation characteristics
 KOREJS, Kryštof
Worldwide environmental effects of anthropogenic land modification have made apparent the urgent need of ecological restoration. However, the methods employed in restoration of post-industrial sites vary across different regions. This thesis aims to examine the outcomes of different restoration approaches by examining avian communities inhabiting a vast spoil heap in Central Europe. Insights into the effects of different types of management and associated vegetation characteristics can guide active restoration of post-industrial sites.

Analýza parametrů sazenic lesních dřevin z hlediska atraktivity pro prase divoké (Sus scrofa L.)

Increasing population of wild boar correlate with increasing damage not only on agricultural lands on crops or grasslands, but also in forests. This damage is mainly on new forest tree plantations which in no way contributes to the successful restoration of clearings after the bark beetle calamity and has a negative impact on the economy. This diploma thesis describes possible influences that may affect the plants attractiveness for wild boar and their damage. An inventory of plants damage was carried out on randomly selected areas in the areas of southern, central and eastern Moravia. A series of experiments with plantings was also performed on the experimental area in the Moravský Krumlov game reserve, where the behaviour of pigs towards these plantings was monitored by the analysis of damaged seedlings and also from pictures taken by photo traps. Obtained inventory data showed us that the wild boar preferred containerized seedlings and deciduous tree species however the experimental system planting did not show a preference for the root system. Seedlings damage was demonstrated in the vast majority only by pulling or rooting without damaging the root system. In terms of time the seedlings were most damaged in the first week after planting, then the risk of damage decreased. To reduce the risk of disturbance by pigs on plantings a method of protection against this damage is not known yet, so the most effective solution remains to reduce the population of wild boar in affected areas.
