Keivan M. Bioindication of the natural environment state in the area of poultry farming

The effect of poultry production on the ecological state of the environment such as biodiversity of entomofauna, the percentage of mature seeds in Robinia pseudoacacia L., the sterility of pollen of plant-bioindicators and the state of pine Pinus sylvestris L. was under study in the thesis. The decrease of biological diversity and profusion of groups of insects was identified . The obtained values of ecological indixes indicate reduced levels of biodiversity in the buffer area farms. The estimation of taxonomic diversity and complexity of groups of insects was carried out, the competitive structure of the studied groups was identified, being a reason for claiming that indicators of biodiversity of insects serve as additional criteria of effectiveness of the impact of poultry production on the state of the environment. The percentage of mature seeds Robinia pseudoacacia L. in the buffer zone of farms is 46.6%, while in the control region - 75.6%, which indicates that the air is polluted in the buffer zone of farms. It was found out that the level of toxic air category of environmental safety on the buffer zone of poultry farming belongs to the class of "dangerous" with a high level of damage and critical bioindicators. The reduce of the absolute values of the length of the needles of pine Pinus sylvestris L. in approaching the farms with higher levels of contamination protection was traced. Thus, the implementation of environmental requirements to livestock should be based on the system of monitoring in the enterprises assessing the condition of natural systems, which are indicators of the anthropogenic pollution.
