The festive trees take eight to 12 years to reach the size most people look for, and young seedlings are particularly vulnerable to climate risks, said Richard Hamelin, head of the forest conservation sciences department at the University of B.C.
VANCOUVER — The effects of climate change are taking a toll on Christmas tree farms across Canada, with one forestry expert and the head of the Canadian Christmas Tree Association saying the sector that's already undergoing shifts will need to adapt.
Seedlings and their shallow roots are also at risk of being inundated during flooding, while wet, cool soils increase the risk of root diseases, Hamelin noted. Brennan said she has spoken with tree farmers from across southwestern Ontario and the Greater Toronto Area, some of whom told her they lost upwards of 40 per cent of their crops as they didn't receive rain between May and August this year."Drought is part of farming," she said. "Mother nature is a silent partner in any farming commodity, whether it's Christmas trees or whether it is corn.
Hamelin noted climate change is also causing warmer weather that fuels activity among pests, which can plague trees already weakened by drought or disease. Since the trees take about a decade to reach the desired size, the closure of tree farms in Canada and the United States during the 2008 recession is now being felt.
Hamelin said the high cost of land and competition with crops that yield revenue more quickly than festive trees may also be inhibiting factors for the sector in B.C.
