Biotope mapping and assessment play an important part in nature conservation and land-scape planning. There are three main types of biotope mapping: a complete, a selective and a representative one. Main tasks of landscape planning and the involvement of biotope and vegetation maps into this instrument are shown. To the biotope evaluation several criteria (parameters) can be referred. A new graduated approach to biotope evaluation is demonstrated, which advances from biotope types via specific single biotopes to the appreciation of biotope regeneration capacity.
