Puiden istuttaminen viljelykelpoiselle maalle tarkoittaa, että tämä ala on poissa vuotuisesta tuotannosta. Systeemin suunnittelusta riippuen tämä voi olla jopa 25% kasvatusalasta. Puista ei välttämättä saa hyötyä vielä moneen vuoteen istu

Urban forests are regularly managed for human safety and esthetic reasons, but they are crucial habitat for many species. Removals of undergrowth occur commonly in these forests, yet the ecological consequences of these operations are poorly understo

The structural matter production of selected plant species of a ground cover community was determined in relation to light available for photosynthesis. The resulting functions were applied in a situation where the light reaching the ground cover was

The tolerance of disturbance of the ground and field layer vegetation in a moderately fertile Norway spruce ( (L.) H. Karst.) on type forest in Southern Finland was studied. One of the sites, a summer cottage yard had been raked regularly during the
