Resumo:  Red Data List of extinct, endangered and vulnerable mosses and lichens in the Netherlands. Lists are presented of threatened bryophytes and lichens in the Netherlands. The threatened species are classified into 5 Red Data categories (0 Extinct, 1 Endangered, 2 Most vulnerable, 3 Vulnerable, 4 Potentially threatened). The list of threatened bryophytes comprises 274 species and varieties, which is about 50% of the bryophyte flora of the Netherlands. The list of threatened lichens comprises 367 species, 58% of the lichen flora of the Netherlands. Not only epiphytic species are heavily threatened, but also species growing on soil and stones. Among the most threatened bryophyte and lichen habitats many are characteristic for the Netherlands, like roadside trees, heath lands, quag fens, and sand dune valleys. The causes of the decrease of threatened bryophytes and lichens are briefly discussed. Most important causes are air pollution, eutrofication and lowering of the ground water table.
