The main results of monitoring of protected invertebrates of Chelyabinsk Oblast after publication of the second edition of the regional Red Data Book

Abstract

The new data on the distribution and bioecological features of 42 species included in the regional Red Data Book have been obtained. These are 37 species of insects, three species of arachnids and two species of gastropods. For 17 species, the data on their distribution in the region turned out to be fundamentally new. Seven studied species are represented in the Red Data Book of the Russian Federation and 36 species in the Red Data Books of other subjects of the Russian Federation. The driving factors of negative impact on the populations of many species are the following: a) intensive, sometimes continuous logging and forest fires, b) large-scale and intensive use of pesticides by farmlands and on the adjacent territories, c) significant recreational load on typical habitats of rare species, d) death of many invertebrates on dirt roads caused by motor vehicles of tenants, hunters, producers of biological products, etc. e) unregulated grazing of livestock, running of horses’ herds, organization of new farmlands and their further active exploitation, as well as fires in the steppe zone. The most vulnerable and sensitive to anthropogenic influence species include Carabus hungaricus, Argyronom laodice, Clossiana thore, Crebeta deidamia, Neolysandra coelestinus, Bombus armeniacus, B. fragrans, B. pratorum and B. veteranus. The state of populations of Parnassius apollo, Bombus terrestris, B. serrisquama, Bombyllus major, Laphria gibbosa and Allohogna singoriensis is not particularly alarming. In our opinion, Anax parthenope, Dendroxena quadrinaculata, Mycetina cruciata, Chelis dahurica, Eresus kollari and Hirudo medicinalis deserve to be listed in the third edition of the Red Data Book of Chelyabinsk Oblast in category III or IV.
