| Description | There are 97 species of orthopterans known from the territory of the CR today. The first conservation status assessment was done in 2005 in the Red List of threatened species in the CR - Invertebrates (Holuša et Kočárek 2005). 29 species are listed there, many others could not be assessed due to lack of actual information. More intensive research conducted in last four years allows to revise orthopteran conservation status assessment. 13 species need to be consider extinct now. 40 % of remaining species occur on very restricted area up to 1% (26 spp.) and 5% (13 spp.) respectively of standard grid mapping squares. Restricted distribution of those species is influenced by geographical location of the country or by limited supply of prefered habitats, often by both factors simultaneously. Most of those species are highly endangered in the CR, only a few of them are spreading quickly there by contrast. Actualised conservation assessment of the orthopterans using IUCN categories and criteria is given. |
