Abstract

Evaluation of trees and shrubs for oil sands reclamation: field trial results.

Abstract

Results are given from 3 field trials established during 1980-81 using native and exotic species on a site prepared to simulate oil sands reclamation in NE Alberta. A fine-mesh fence was erected around the site to exclude small mammals. All species were planted as 1- or 2-yr-old container stock. In Aug. 1986, survival rate was high for most species. The exotic Populus 'Northwest' and P. 'Tristis No. 1' were the tallest and fastest growing species. Of the 11 native species, Pinus banksiana was the tallest and fastest growing. Other species that performed well and may be suitable for oil sands reclamation included the exotics Caragana arborescens, Elaeagnus commutata and Populus 'Brooks No. 6', and the native Cornus stolonifera, Empetrum nigrum, Picea glauca and P. mariana. Provenance had little effect on the measured variables in the native species.
