Abstract: Tendencies in landscape use in Portugal, such as abandoning agricultural land, accompanied by the
intensification of urbanization, resulted in the development of highly heterogeneous land mosaics
in most cases with dissimilar conditions for bryophytes. The study area, located in mainland
Portugal, known as the “Baixo-Tâmega” Region, was the target of a project aimed at evaluating the
territory as nature conservation and management value area. A methodology of land cover evaluation
for this mountainous area is presented here, based on expert knowledge and the results shown
in a map according to aspects of conservation for bryophytes. A positive correlation between the
highly valued areas and the total and threatened bryophyte species richness provided evidence that
biological valuation can be a useful tool for conservation and management of semi-natural areas.
Furthermore, we showed that landscape configuration (e.g. heterogeneity, size and ecotones of
natural and semi-natural mosaics) and landscape composition (e.g. low scrublands) are relevant for
the occurrence of threatened bryophyte taxa and these must be taken into account in conservation
management and planning at the landscape scale.Keywords: threatened species, conservation value maps, expert knowledge, hotspots, land cover
