Protection
Since the result of human activity has undergone enormous changes in the natural environment, butterflies, as its inherent elements in a way that negatively affected by these developments. Decreased the number of species and abundance of many populations. So in order to effectively protect this group of insects is the primary responsibility to protect their natural environment. Any change in the plant affects the survival of butterflies and moths. Conversion of habitat due to the way forest management, agriculture, wetland drainage areas L and other forms of economic activity ~ | tion of human causes of local extinction of many | of the population. However, the absence of any interference | sometimes it can be disastrous for some? species. For example, if a meadow is cut will not, it porośnie shrubs and trees and the environment will cease to be associated with meadow species. Similar processes can happen in any type of environments.
Number of species of butterflies and their number varies each year, it is a natural state of things, provided that these changes are not too violent. Many species are very sensitive to climate change. Central Europe is for some butterflies and moths the northern ends of the range of their occurrence. They are common in parts of southern Europe. Warming may lead to the fact that the southern species is spreading further north, and species zimnolubne will shift even further
toward the pole. Improving conditions on the Aland Islands in the north allowed the colonization of the Baltic Sea by a butterfly and Vanessa. Tracking changes in abundance of each species over a longer time is called monitoring. In many places around the world on special maps divided into squares indicate the presence and abundance of species of butterflies and moths. Such maps facilitate the observation of changes in abundance and changes of quality, allowing for a more rational and effective protection.
