Why Ash Matters in Brandon
Brandon has about 15,000 ash trees, according to the City of Brandon. Its invasive-species guidance describes emerald ash borer as a serious threat because the larvae feed on the tree's nutrient-conducting tissues. The size of the local ash population makes awareness useful even without a confirmed local finding.
For a homeowner, the practical questions are separate: what is happening to the tree, where has the insect been officially recorded, and how should wood be handled? A change in an ash tree's appearance is a reason to investigate. It is not, by itself, evidence that emerald ash borer has reached a particular neighbourhood.
Where Emerald Ash Borer Stands in Manitoba
The Canadian Food Inspection Agency's emerald ash borer page, modified July 27, 2026, lists the city of Winnipeg as the Manitoba location where the insect is present and regulated. That listing should not be read as a finding in Brandon or the wider Westman region.
The CFIA describes the beetle as attacking and killing ash species in the genus Fraxinus. Infested ash trees in North America generally die after two to three years; heavily infested trees have sometimes died after one year. These figures describe infested trees, rather than a forecast for an ash simply because it grows in Manitoba.
How the Beetle Spreads
According to the CFIA, the most common route of spread is the movement of firewood and other infested ash wood products. Adult beetles can also fly, with research showing flights of up to 10 kilometres. Both routes matter, but moving wood gives the insect a way to travel with people.
Firewood and bark may contain eggs or larvae that are difficult to see. A clean-looking log is therefore not a reliable test for whether it carries a pest. The City's guidance is to buy firewood locally and leave it where it was bought. Avoid making a trip with leftover logs simply because they appear sound.
Signs to Watch For on an Ash
The CFIA says early detection is challenging because the beetle is small. Its guidance instead draws attention to changes on the tree, including woodpecker feeding, yellowing leaves, branch dieback and epicormic shoots on the trunk. S-shaped galleries made by larvae may be visible where bark has already been removed.
Keep those observations specific: note which branches have died back, where shoots are appearing and what changes are visible in the leaves. Avoid turning a list of signs into a diagnosis. It also does not provide a reason to strip bark from a public tree; Brandon's public-tree protections apply even when a resident is concerned about insects.
Firewood Rules for Ash and Elm
The CFIA's firewood guidance, modified September 22, 2026, recommends buying wood cut less than 80 kilometres from where it is sold. Asking where wood was cut is more useful than assuming that a nearby seller means a nearby origin. Buying locally and burning locally helps avoid carrying pests between places.
Regulated-area restrictions are a separate issue from that distance recommendation. The CFIA says moving firewood out of a regulated area is prohibited except for heat-treated firewood with a CFIA movement certificate or wood moved under a compliance agreement. Moving firewood from places with regulated pests can violate the Plant Protection Act, with penalties of up to $50,000 or prosecution. Check the applicable movement restrictions before transporting wood.
Elm wood has its own local rule. The City says using elm as firewood is illegal; removed elm wood should be burned, buried or chipped. Dead or dying elms attract elm bark beetles, which can continue the Dutch elm disease cycle. Keeping elm logs for later firewood use conflicts with that guidance, regardless of concerns about ash.
Planning Ahead for Ash on Your Property
Planning can begin with the tree and the planting space rather than a prediction about when a pest might arrive. The CFIA recommends alternatives to ash when replacing ash trees that have died. Suitability for the planting site remains part of that decision, including potential conflicts with utilities, sidewalks, driveways and structures.
The City's 2026 tree reimbursement program specified species suitable for Manitoba or Zone 2b and required at least two years of homeowner maintenance, including watering and mulching. That program reached full capacity and is no longer accepting applications. Its planting criteria still illustrate useful questions about hardiness, space and continued care, without suggesting funding is available.
