The Sawyer Preservation Woodlot Association was established in 1989 and acts as a "trustee and guardian" for a 28.61 acre wooded tract located in rural southwestern Ontario. The mandate is to manage the property so as to maintain Red Trillium the richness and diversity of the species within its boundaries and to encourage and promote stewardship of the declining wooded areas of this country. In so doing, the property is maintained as a demonstration woodlot and conservation area where the public is welcome.

The woodlot often hosts organized visits ranging from school children to the "Back Road Tours". Abundant flora and fauna attracts a broad spectrum of individuals -- conservation specialists -- the serious nature lover -- those simply wishing solitude. Each visit will provide a new experience. Every day is different -- each season presents its own offering. Wildlife abounds. Residents and transients; common and rare. Each encounter provides that tingle of excitement as one takes in what nature has to offer.

Another Woodlot Threat Coming Our Way

Oak Wilt — fungal pathogen (Ceratocystis fagacearum)
Oak Wilt Oak Wilt results from a fungal infection that creates fungus colonies under the bark of oak trees that prevent nutrient flow. Once infected, the tree usually dies within a year. At this point, it appears that all oaks are vulnerable, but so far does not extend to other tree species.

You first notice the problem when the tree begins to "brown" beginning at the top, and individual leaves take on an appearance as shown here. Closer inspection will identify bark sections that have cracked and raised due to a fungus mat just below the surface. Progression varies from tree to tree, but the end result will be the same.

To this point in time, there have been no confirmed cases of Oak Wilt in Canada. However, more than 100 oak trees have been lost on Belle Isle in the Detroit River — a mere 600 metres from Windsor. To date, more than a half million oaks have been lost in Michigan State Parks alone. There are numerous infected pockets on the west side of Lake Huron ... about 150 km from our shore. It is not impossible for the fungus spores (or the transporting insects) to get caught up in a weather incident and travel across the lake to our doorstep.

Oak Wilt The fungus spreads in 2 ways. Firstly, sap and bark feeding beetles are attracted to ailing or damaged trees and, as they feed, they pick up the fungus spores and then transport them to their next tree. The most active time for this are the months of April through August. Secondly, the fungus can transport systemically and will spread through the tree's root structure to neighbouring oaks. Oaks are known to have interconnected root systems.

There is no practical cure or treatment for this disease, however some areas are working with fungicides but cost and physical danger discourage this. Prevention is the only course of action. Do not prune, cut or damage the tree during the vulnerable months. If such happens, fully paint open wounds with a wound or latex paint. This will prevent or discourage the sap beetle activity. Remove dead/infected trees. Chipping, splitting, debarking, burning or burying works. DO NOT transport the wood, as fungal spores can survive in the dead wood for more than a year, and you do not want to move it into a clean area.
