Spraying and Fires In BC

Earlier this year, mass spraying of chemicals in our regional forests began, licensed to continue until April 2029. This initiative targets invasive plants on Provincial Public Land under the jurisdiction of multiple ministries, including Forests, Transportation and Infrastructure, Water, Land and Resource Stewardship, Environment, and Climate Change Strategy. The areas affected include Southern and Coastal British Columbia and Northern Coast Haida Gwaii, covering regional districts such as Alberni-Clayoquot, Capital, Cowichan, Cariboo, Central Coast, Central Kootenay, Central Okanagan, and more.

The methods of application include mechanical, cultural, biological control, and herbicides applied via wick/wipe-on, stem injection, ground vehicle-mounted sprayers, backpack, and handheld sprayers. The chemicals used include various herbicides such as Aminocyclopyrachlor (Truvist), Aminopyralid (Milestone), Clopyralid (Lontrel XC), Dicamba (Dyvel), Diflufenzopyr (Overdrive), Fluroxypyr (Starane), Glyphosate (Roundup), 2,4-D (2,4-D Amine 600), Imazapyr (Arsenal), Metsulfuron-methyl (Escort), Picloram (Tordon 22K), Florpyrauxifen-benzyl (Rinskor), and Triclopyr (Garlon). These herbicides have various environmental and health impacts, ranging from toxicity to aquatic life, vegetation, insects and other health issues in humans and animals..

The forestry industry, along with provincial authorities, also engages in similar practices. Researchers have raised concerns that glyphosate spraying might exacerbate wildfire risks. Glyphosate, the active ingredient in Roundup, is used to eliminate slow-burning hardwood species such as aspen and birch to promote the growth of more profitable coniferous trees like pine and spruce. This practice, widely adopted by the Canadian forestry industry, aims to streamline cut blocks for commercial purposes. However, hardwood species burn more slowly and can act as natural fire barriers. During the 2017 Williams Lake fire, mixed forests with aspen trees saw significantly less damage compared to conifer-dominated areas.

Despite the benefits of maintaining hardwood species, the forestry industry (along with the Province who does so for “invasive” foliage) continue to use glyphosate extensively, spraying thousands of hectares of public forest annually. Critics argue that this approach not only makes forests more flammable but also undermines other ecological values. James Steidle, a woodworker and member of the Stop the Spray B.C. movement, describes the industry’s view of forests as overly simplistic, comparing it to a vegetable garden where non-coniferous species are eliminated like unwanted weeds.

The BC Council of Forest Industries defends its practices, claiming they follow strict sustainability criteria and that glyphosate is applied precisely to minimize impact. However, researchers highlight the broader ecological implications, noting that glyphosate residues remain in surviving plants for at least a year, potentially causing unknown long-term effects. Diverse forests offer additional benefits such as mitigating disease, limiting insect infestations, and sequestering carbon dioxide. Some argue that current forest management practices are outdated and overly focused on financial gain at the expense of ecological health. The province of British Columbia mandates a predominantly coniferous forest on cut blocks, contrary to the natural diversity of these ecosystems.

Moreover, glyphosate’s extensive use raises environmental and health concerns. It is associated with non-Hodgkin lymphoma and has adverse effects on beneficial bacteria in soil and water, as well as being harmful to bees. Herbicides like 2,4-D, once used as Agent Orange, pose risks such as endocrine disruption and decreased fertility. These chemicals can cause serious health issues, including eye damage, skin irritation, and reproductive problems.

In addition to aerial spraying, methods like “hack and squirt” and “cut and treat” are employed to manage forests. These techniques involve injecting or applying herbicides to tree stumps to kill non-desirable species. While intended to manage forest composition, these practices leave behind dry, dead biomass that increases fire risk.

Public awareness and education about local forest management practices are crucial. Understanding who controls local forests and their management strategies can reveal the impact of herbicides and other chemicals on forest fire dynamics and local water supplies. The public needs to engage in discussions and advocate for more sustainable and ecologically sound forest management practices to prevent the adverse effects of current methods. Quebec remains the only Canadian province to have banned glyphosate use in forestry entirely, setting an example for others to follow.

Maybe it is time to start pushing for, and promoting, the use of alternative forest management practices, such as controlled burns, mechanical thinning, and promoting the growth of native species, can help reduce fire risks without the adverse effects of herbicides to our ecosystem and our health and safety.
