Analyse einiger Unterrichtskonzeptionenerating crops in this way. It can usually be repeated many times and is a useful means of regenerating broadleaved trees within short time intervals (less than 30 years) to produce small roundwood.

For centuries coppicing was the usual method of managing woodland in the lowlands and coppiced woods are now generally regarded as valuable for nature conservation (Rackham, 1980; Peterk

The latter is also characteristic of areas of freq

The density and species composition of soil seed banks depend on the rate at which seeds enter and are lost from the soil. In frequently disturbed habitats, seed banks
