Ecology and abundance of a relict population of the bush cricket in the Northern Apennines, Italy.

The expansion of forest cover and intensification of agriculture represent the main threats to the bush cricket , currently listed as Vulnerable globally by the IUCN and included in Annex IV of the European Union Habitats Directive. Gathering information on its ecology and population size is challenging due to its low abundance and localized distribution. Additionally, the elusive and cryptic behavior of this species reduces the likelihood of its detection, potentially resulting in population underestimations.
