Large Tree Stock Selection

Private Client, Township of Centre Wellington, 2011-2012


The planting of a tree represents an investment in the future. Arboricultural personnel at Aboud & Associates have expertise and extensive experience in the evaluation and selection of healthy and structurally sound tree planting stock. While critical to the long-term success of all our projects where discerning selection of tree stock is needed for trees afforded high value, trees expected to thrive for many decades, and where future structural training of trees is to be minimized; this particular project is unique in that all proposed trees were between 20 to 25-feet at time of planting to create an instant impact.

Eden Park Butternut Health Assessment

Corporate Client, Hamilton, 2011-present


Classified as an endangered species under Ontario’s Endangered Species Act (2007), the entire population of Butternut (Juglans cinerea) trees throughout North America is in rapid decline due to Butternut Canker disease. Following the Ministry of Natural Resources Butternut Health Assessment Protocols, our certified Butternut Health Assessors determined the health of on-site trees and prepared compensation planting contract documents to aid in the survival of the species by using genetically verified pure Butternut stock with disease resistant characteristics. To ensure long-term success we developed an intensive maintenance and monitoring program, currently in progress.
