Collection of propagation material in the absence of genetic knowledge

Abstract

Genetic variation within and among popula- tions has not been studied in the vast majority of tree species. This makes it difficult to plan ef- fective germplasm collection strategies for forest restoration and species conservation purposes. This paper provides guidelines for collection of propagation material for forest restoration when knowledge of genetic variation between and within populations is lacking. Rare species that occur as scattered trees or in small cohorts growing hundreds of metres apart are unsuitable sources of propagation material for stand estab- lishment since they never form stands in nature. Therefore, this paper refers to commonly occur- ring species. Forest restoration projects may also aim to con- serve the genetic diversity of the species used, but for a specific treatment of sampling for gene con- servation in sensu stricto, the reader is referred to Eriksson (2005a). Evolutionary factors are pre- sented to help understand the existing genetic variation between and within populations.
