CONSERVATION PROBLEMS OF BEE FAUNA (HYMENOPTERA: APOIDEA, APIFORMES) IN RESERVE „GÓRA GIPSOWA”

Abstract

Preliminary results of research conducted in July of 2008 and 2010 in xerothermic plants reserve “Góra Gipsowa” in NW Poland were presented. During field surveys 75 species of Apiformes were found: Colletidae (9 species), Andrenidae (11 species), Halictidae (17 species), Melittidae (3 species), Megachilidae (19 species), Anthophoridae (5 species), Apidae (11 species). It is a significant number, especially when taking into account insular character of the reserve, small area, impact of surroundings and that investigations were limited to summer period. Number of species obtained in 2010, which is several times lower than obtained in 2008, indicates strong anthropopressure on the environment and corroborates the necessity of the appropriate ecosystem protection, wich would ensure the existence of precious plant species as well as much more vulnerable xerothermic fauna.
