On assessment of the conservation effectiveness of Red Data insect species in the territories of a nature reserve and a nature sanctuary within the same reservation area (by the example of Voronezh Biosphere Nature Reservation)

Abstract

A category scale of the status of Red Data insect species occurring in the territories of Voronezh Biosphere Nature Reservation and appropriate numerical values (from 0 to 4) of the state index (SI) of insect species are developed. This scale is compatible with the rarity categories used in the Red Data Book of the Russian Federation (2001) and in the regional Red Data Book of Voronezh Province (2011) and Red Data Book of Lipetsk Province (2014). Based on long-term field data and collection material, the status and SI are characterized for 14 insect species listed in the Red Data Book of the Russian Federation and the regional Red Data books and occurring in the territories of the Nature Reserve (shared between Voronezh and Lipetsk provinces) and Nature Sanctuary within Voronezh Biosphere Reservation. The Red Data species showing a positive difference between the SI value in the territory of the Reserve or Sanctuary and the SI listed in the Red Data Book of the Russian Federation (or a regional Red Data book) are considered to be efficiently protected in the Reserve or Sanctuary, respectively. Six Red Data insect species were found to be efficiently protected in the Nature Reserve, and only four species in the Sanctuary.
