Is the Current Forest Management to the Northernmost Population of Cordulegaster heros (Anisoptera: Cordulegastridae) in Central Europe (Czech Republic) Threatening?

Cordulegaster heros is included in the EN category on IUCN Red List for territory of Czech Republic, where it inhabits an area approximately 100 km2. All localities are located forest complex Chřiby hills, and all forests fall into management forests. Most stands have a high very degree naturalness; they natural stands. The predominant units Nutrient sites middle elevations (78.2% area) Oligotrophic (2.1% area), with stand types Fagus sylvatica representing 92.5% area, Quercus sp. 5.7% area. wider alluvia streams classified as being unit alder ash waterlogged floodplain soils (1.1%), type Alnus glutinosa. restored by regeneration under shelterwood (97.8% area). alluvia, if separate established them, strip method. Realistically, seven factors were recorded C. habitats, but mostly only point effects. Within forestry management, logging directly habitats subsequent transport harvested timber habitat recorded. most intrusive effects found tractor roads, fine soil washes stream causes prolonged turbidity. Of water structures study roads bridges culverts constructed, banks reinforced longitudinal walls at points, stone steps channels constructed sporadically. current system can be described nature-friendly system, therefore, fully ensures conditions survival population Republic.
