Abstract

Forest ecosystems are characterised by the most abundant biodiversity because there are the best conditions for existence of various species of plants, animals and various other organisms there. Generally, in the last decades a lot of attention is given to biodiversity, and scientific research draws attention to an increasing loss of biodiversity. Biodiversity measurements are needed in order to understand biodiversity changes and to control them. Measurements and assessments of biodiversity of ecosystems reveal the condition of an ecosystem of a certain territory as well as create the basis for a strategy of preserving separate species. A lot of indices for assessing biodiversity risk have been created in the last decades. Integrated indices are composed when joining indices, and one of them is the integrated biodiversity risk assessment index NABRAI (National Biodiversity Risk Assessment Index). This article analyses the principles of creating biodiversity risk indices, possible alternatives of components (variables of biodiversity resources, impact and response indices), and their suitability at the national level. Assessment and ranking methodology, adapted for assessment of biodiversity risk of local protected territories and for ranking of territories, is presented. Report data of directorates of Lithuanian national and regional parks are used for the analysis, as well as the data served as a basis to calculate integrated biodiversity risk indices of several protected territories of Lithuania.
