Zur Rückkehr der Arve (Pinus cembra L.) in die Südalpen der Schweiz | The return of the Swiss stone pine (Pinus cembra L.) in the southern Alps of Switzerland

The ecology and spread of the stone pine in the subalpine zone of southern Switzerland are discussed with reference to both vegetation releves with Pinus cembra L. from Vergeletto valley (Canton Ticino) and forest history and botany publications. The ecograms and lists of tree species given in the recent literature are often contradictory, so that it is difficult to use them with confidence. This means that only verifiable and published releves and analyses based on them may serve as a basis to evaluate the implementation and check the results of forest management in Switzerland.
