Popis:	The characteristics of soil seed banks in Agathis australis (kauri) forests of northern New Zealand are presented, and variations in seed bank composition are described in relation to stand age and distance from forest edges. A mean viable seed density of 1118±217/m2 was present under the kauri forest sites. While the seed bank contained both native (77%) and adventive species (23%), its composition was not closely related to that of the extant vegetation. The abundance of adventive and native herbaceous components of the seed bank declined as stand age increased, while that of native woody secondary species remained relatively constant. The abundance of adventive species also declined significantly with increasing distance from forest edges.
