Performance of Quercus rubra and Quercus robur in pure and mixed-species plantations

Abstract

Quercus robur L. and Q. rubra L. (pedunculate and Northern red oak, respectively) produce high-value timber. Mixed plantations are attracting attention because they provide several benefits; however, they have been included in few trials in non-native habitats. This study assessed growth, health, and timber quality of Quercur robur and Q. rubra trees growing in pure and mixed plantations including companion tree species.
