Skyjack is helping The Arboretum, University of Guelph to preserve rare trees. Skyjack recently loaned a SJ63 AJ articulating boom lift to assist The Arboretum to collect difficult-to-access seeds from the Rare Woody Plants of Ontario seed orchards, including seeds from Cucumber Trees, Big Shellbark Hickory, Chinquapin Oak, Kentucky Coffee Tree, Tulip Tree, and the Sycamore.
Many of the trees species in the Arboretum’s seed orchards grow naturally in the Carolinian Forest Region in Ontario, which only occupies a small part of southern Ontario. A combination of a small natural growth area and habitat loss have caused many of the trees species to become listed as threatened by the Committee on the Status of Endangered Wildlife in Canada (COSEWIC).
Sean Fox, head horticulturist, The Arboretum, University of Guelph, said the SJ63 AJ allowed for greatly increased access to seeds within tree canopies, not only for areas that were too high to access in the past, but even lower portions that have difficult to access angles.
“With the use of the Skyjack lift, we were able to collect more seeds, including seeds on some species that we’ve been unable to access in the past—in about a third of the time,” Fox said.
In the past, the Arboretum collected seeds using a combination of ladders and hooks to lower branches. Staff used a 17 ft orchard ladder but it was difficult to place within the canopies.
“Climbing many of the trees was impractical as much of the seed is concentrated on small branches at the edges of the trees’ canopy and many of these upper branches are not large enough to support the weight of a climber and equipment,” Fox said. “With Skyjack’s lift, we were able to access the seeds in a safer and more efficient manner.”
The seeds collected from the various rare trees will be used for multiple purposes. Batches will be sent for long-term preservation to the National Tree Seed Centre, a division of the Canadian Forest Service in Fredericton, New Brunswick. Some of the seeds will be used in the Arboretum’s Tree Nursery to produce seedlings that will be shared with other botanical gardens and research agencies for further archiving. Some of the seeds will also be distributed to selected tree nurseries to produce offspring that will aid in restoration programs in the tree’s native range.
“The seeds we collected from the Arboretum’s Gene Banks will help to reduce seed collection pressures on the wild populations,” Fox said.
Editor's Note: This particular SJ63 AJ was painted pink in honor of Breast Cancer Awareness Month. Skyjack is donating a portion of proceeds from sales of Skyjack boom sales in October to benefit the Canadian Breast Cancer Foundation.
