To help keep the trees around your home and yard healthy, happy, and safe, it is important to have regular, bi-annual tree inspections from an experienced ISA Certified Arborist. It is important that you choose an ISA Certified Arborist. The ISA (International Society of Arboriculture) is the only industry-recognized credentialling body that deems an Arborist knowledgeable, experienced and trained to care for your trees. Trees can improve your property’s environmental, aesthetic and resale value (as much as 17%!) provided they are inspected and cared for to keep them healthy, vigorous and managed professionally for maximum enjoyment on your property. At Beautiful Trees Inc., our experienced, ISA Certified Arborists can help you evaluate your trees and create a customized tree care plan to improve tree health, structure, and to help support their role as the most dominant living features of your landscape. Regular inspections twice yearly can result in early detection of structural and pest issues, resulting in swift corrective measures that can prevent the types of branch and tree failures that are associated with unmanaged landscapes.
Our ISA Certified Arborists conduct regular tree inspections to detect structural defects and weaknesses, fungal infections, insect infestations, and other hazardous conditions so they can be managed and mitigated before they pose a safety risk to your property. During these inspections, Beautiful Trees Arborists will also take the time to identify other potential safety concerns such as large hazardous deadwood or dense canopies that resist air flow and have a higher probability of resulting in breakage during one of the extreme weather events that are becoming more common during these times of climate change.

During the growing season, our ISA Certified Arborists assess tree health by inspecting your tree’s seasonal growth patterns, leaf size and colour and other physiological and physical characteristics that allow us to identify the tree’s current state of health and to forecast any future issues that may arise. During these inspections, we may require a climber to be sent into the canopy of the tree to inspect the tree more closely. Our ISA Certified Arborists can also check the tree using tools to assess the current structural state of the tree – whether it is currently hollow if the wood is solid or “punky”, and if there is “included bark” which reduces the strength of branch unions on trees.
Our ISA Certified Arborists are also trained in insect and disease identification to help detect pests early and ascertain whether any management techniques are necessary to mitigate negative impacts on tree health that could lead to future defoliation, dieback or failure.
Inspecting your deciduous (trees that shed their leaves in the autumn) trees during dormancy is one of the best times of year to efficiently detect signs of decay, disease, or structural weaknesses. Our ISA Certified Arborists routinely conduct tree inspections from November to April to easily inspect for visual signs of stress cracks, occluded bark, branch attachment, poor structure, dead wood and decay. In fact, much of the arboricultural pruning and management practices can be carried out during the dormant season. Where there is adequate access to the property for equipment in winter, pruning can often be completed in less time than it would take when there is a full complement of leaves on the tree. Dormant tree inspections coupled with growing season inspections is the best protocol for ensuring that your trees are carefully monitored and cared for to minimize stress or hazards.
Another great time to inspect your trees is just after a storm passes through your region. Strong winds and weather events can be detrimental to the tree’s structural strength and can completely change the safety rating of your tree. Accumulations of ice can add thousands of pounds of weight to the branch tips, causing breakage if sub-zero temperatures are prolonged (such as what we experience in December, 2013). It is important to call an ISA Certified arborist to inspect your trees after a storm event to assess whether any corrective pruning or bark tracing needs to be carried out to facilitate proper healing and recovery.
