Where a number of threatened species depend upon a specific habitat, it may be appropriate to prepare a habitat protection element of the Biodiversity Action Plan. Examples of such special habitats are: raised acidic bogs of Scotland; Waterberg Biosphere bushveld in South Africa; California's coastal wetlands; and Sweden's Stora Alvaret on the island of Öland. In this case also, careful inventories of species and also the geographic extent and quality of the habitat must be documented. Then, as with species plans, a program can be created to protect, enhance and/or restore habitat using similar strategies as discussed above under the species plans.
