Bewertung lichter Wälder im Kanton Zürich und der Nutzen für das Projektmanagement | Evaluation of open forest in Canton Zurich and its significance for project management

In 2004, the canton of Zurich possessed 376 hectares of uninterrupted open forest. Such stretches of forest provide essential habitats for animal species that favour both light and heat. Standardised surveys, and available data relative to existing flora and fauna has greatly facilitated the evaluation of the forest's vegetation and inhabitants. This contribution presents both the methods used, and the initial results. The advantages and disadvantages of the so called LiWa-indicator are discussed, and the way this evaluation method can be used to manage the plan of action entitled «Open forests in Canton Zurich» is illustrated.
