Preliminary study using lichen species diversity as an indicator of local environmental quality within two nature reserves from Romania

Within this study was emphasized the difference between the high degree of conservation of Glodeasa Forest Reserve and the impact of eutrophication as a result of human activities from M lu teni Nature Reserve using lichen species diversity. The major human activities with a strongly impact on environment quality in M lu teni Nature Reserve area are following: the livestock operations and the crop farming. A comparative assessment on the two protected areas pointed out a significantly differences regarding the preferences of inventoried lichen species to nitrophily. Thus, it was recorded a highest percentage (67%) of nitrophilous lichen species within M lu teni Nature Reserve in contrast with a highest percentage (93%) of anitrophilous lichen species inventoried from Glodeasa Forest Reserve. The prevailing of some rare and threatened lichen species within Glodeasa Nature Reserve represent a sensitive indicator of highest environmental quality.
