Abstract

It is necessary to study the structure of natural masses to understand the evolutionary stages and dynamic process in unmanaged forests to apply methods in sync with nature. The ecological importance of the deadwood has led to the increasing collection of information about them and their consideration in management plans. Numerous organisms are active in the deadwoods in forests, among which insects have the highest number of species. Given that the conservation of biodiversity is essential for sustainable development, in this direction, recognizing the species diversity of forest complex ecosystems is very momentous. To identify species diversity of saproxylic Diptera in Hyrcanian forests, sampling was performed using pan traps during 2017-2018 in Gilan, Golestan, and Mazandaran provinces. In all, 71 species belonging to 22 families of saproxylic Diptera were collected and identified from Hyrcanian forests, among which two new species were described, and 20 species were reported for the first time from Iran. The result showed that the species diversity of saproxilic diptera in unmanaged forests is higher than in managed ones, which reveals the necessity of protecting these forests.
