A method for the quantitative evaluation of the endangerment status of Trichoptera assemblages in Hungary

摘要

An endangered species categorisation of the Hungarian Trichoptera has been proposed by NÓOMDI and UHERKOVICH(1999). However, their list did not allow a quantitative evaluation ofudthe degree of endangerment. Here an attempt is made to calculate an index of endangerment among the different groups of the endangered species categorisation of NÓOMDI and UHERKQVICH (1999).
