Juglans mandshurica: A new alien walnut species for the flora of Türkiye

Abstract

Juglans mandshurica Maxim. (Juglandaceae) is recorded as a new woody alien for the vascular flora of Türkiye. Tree-ring evidence from the oldest individual indicates that the taxon was introduced to Artvin- Kemalpaşa at least 19 years ago, a finding supported by observations of both mature individuals and numerous seedlings in Kemalpaşa and the other observed locations. This suggests that J. mandshurica is becoming naturalized and could potentially become an invasive species in the Northeast Anatolia region, where several non-native woody species (e.g. Spiraea japonica and Rhus chinensis var. chinensis) have already been recorded. This walnut species is estimated to have been introduced both by humans for its edible seeds (intentionally) and through scatter-hoarding by crows (unintentionally). Its description, illustrations, and photographs, together with a diagnostic key to the species of Juglans in Türkiye, are given to facilitate easy identification.
