Contribution to the lichen flora of the Alvados valley, Natural Park of Serra de Aire e Candeeiros (Central-western Portugal)
Quercus faginea woods in Alvados valley are remnants of ancient forest within a strongly fragmented and diverse human-made matrix. In this contribution, new data concerning lichen diversity characterizing this area are presented, including two species new to Portugal. More than 20% of the species are typical of undisturbed, natural environments confirming these woods to be important areas for preservation of specific lichen flora.
