During the first half of October, we payed a visit to our foreign partner RNDr. DI Karl Černý (Gerichtlich beeideter Sachverständiger für Ökologie und Insektenkunde) in Austria. The aim of the meeting was the joint implementation of active management at sites around Innsbruck, which host an endangered fauna of diurnal butterflies, with a number of unique species from other taxonomic groups as well. As part of the management measures, we hepled to eliminate expansive woody plants and bramble stands, which are also a significant problem on some of our areas in Prague. Through an active approach and especially the subsequent consultation, we gained very valuable knowledge about how to effectively solve these problems with overgrowing of xerothermic habitats in the long term. We look forward to further active cooperation!
