The study of rare and endangered taxa is considered to be of major importance, underpinning any conservation measures and declaration of protected areas. As a result of global warming, but also human impact, the Carpathian Mountains have been included in some predictions as a potential area of species extinction in the coming century. Alpine and sub-alpine plant species ("High Mountain Taxa", HMT) are among those most affected by climate change. The project will create a geo-referenced database of the distribution of rare and endangered taxa of subalpine-alpine plant species in the Romanian Carpathians. Using the distribution data, species distribution patterns will be modelled, and potential locations, where the species might occur, will be determined. The most interesting potential locations will then be verified in the field and additional species information will be collected. With the new information, the database will be improved. Areas of interest will be estimated in terms of rarity and their inclusion in existing National and Nature Parks. The database will serve as a starting point for the inclusion for study of other species as well as the impact of climate change on these rare and endangered taxa.
