Comparison of Střezovská rokle natural monument with similar brown caol post-mining sites developing under the spontaneous succession

Minerals resources mining leads to soil degradation in the area of north Czech. Extensive dumps form because of brown coal mining. Unnecessary material of mining place imposes there. These areas are rehabilitated due to recovery of landscape. Natural of renewe procedures are more valuable biologically spontaneous ekological succession especially.These successional areas have been compared with similar protected territory. Its name is Střezovská Rokle. To compare I have used sample group of Aculeata Hymenoptera. In ravine six areas have been compared with six dumps with active primary succession (dump Radvesická, Obránců míru, Velebudická and Vršanská). All of these are situated to Severočeská hnědouhelná pánev. Acuelata insect is from three salvages (may, june, july). I have used technique traps of Moerick. Overall 176 kinds of Acuelta hymenoptera insect have been found out in both locations.They have classified according to taxanomic inclusion. There are three menials (apoidea, vespoidea, chrysidoidea). Some detected kinds of insect have been significant types which have been determined by Red List. Altogether 45 kinds of insect have been registred in both locations. 8 types have been registred in Střezovská Rokle and 37 kinds at dumps. They are compartmentalized to few categories by vulnerability. The biggest prevailing menial is Crabronidae. It reaches the biggest abundance in Střezovská Rokle (6 kinds) and in dumps as well. Occurrence of significant kinds at dumbs surpasses protected territory Střezovská Rokle positively
