A recent assessment of cricket and grasshopper species in Europe has shown that up to 25% are facing extinction. According to the International Union for Conservation of Nature (IUCN), the group Orthoptera, which includes Grasshoppers, Crickets and Bush Crickets, is the most threatened group assessed so far. An estimated 1000 species of Crickets and Grasshoppers are found in Europe. They play a vital role in grassland ecosystems; many species of birds and reptiles feed on them. The main factor contributing to decline is habitat loss due to wildfires, tourism and intensive farming. Many species are confined to small areas due to the break up of their natural habitats; for example the Crau Plain Grasshopper has been confined to the steppes on Southern France.
So what can be done in order to protect these insects? According to research from the IUCN Global Species Programme, more effort must be put into restoring the habitats of these insects in order to increase population size. This can be achieved using sustainable grassland management by employing traditional agricultural practices. It is imperative that these insects are saved from extinction, not only because they are very important biodiversity indicators, but also they are an integral part of grassland ecosystems.
