Maine Aerial Forestry Spray Ban of Glyphosate and Other Herbicides Vetoed by Governor, Override Effort Begins

(Beyond Pesticides, June 29, 2021) Maine Governor Janet Mills (D) last week vetoed legislation prohibiting the aerial use of glyphosate and other dangerous herbicides in forestry practices. LD125, An Act To Prohibit the Aerial Spraying of Glyphosate and Other Synthetic Herbicides for the Purpose of Silviculture, was supported by a wide range of health and conservation groups, and aimed to bring the state in line with best practices for public health and the environment. With Maine recently passing one of the strongest consumer bans on pollinator-toxic neonicotinoids, advocates are dismayed by the setback from the Governor’s office. In a statement to Maine Public Radio, Senate President Troy Jackson said that Governor Mills should stop referring to herself as an environmentalist. “The science across the country, across the world, says that this stuff kills people, kills wildlife,” Mr. Jackson says. “And all that it is, is a giveaway to the large landowners so they can maximize their profits off the lives of the people in Maine and the wildlife in Maine.” Senator Jackson’s words are stern yet factual. Glyphosate has been identified by the World Health Organization as a probable human carcinogen. Monsanto, now owned by Bayer, has been the subject […]

Forestry Use of Glyphosate Reduces Fertility of Perennial Flowers and May Reduce Pollination

(Beyond Pesticides, June 22, 2021) Glyphosate herbicide use in forested areas persists in the environment for years and can prompt morphological changes in perennial flowers that reduce their fertility and may make them less attractive to pollinators. These findings were published this month in the journal Frontiers in Plant Science by researchers at the University of British Columbia, who hope that their work will inform safer approaches to forest management. “The more we learn the better, and research can always be used to better inform management,” said lead author Lisa Wood, PhD. “Herbicide practices may change, if the research shows that this is in the public’s best interest.” Glyphosate herbicides like Roundup and Visionmax (a Canada-registered glyphosate product produced by Bayer/Monsanto) are often applied aerially via helicopter on wide swaths of forest land known as cutblocks. Cutblocks, designated areas where coniferous trees are grown for harvest and processing, are doused with glyphosate in order to manage understory trees and shrubs that would compete with the conifers. Researchers set out to understand the nontarget impacts of this practice on the surrounding forest ecosystem. Wild prickly rose (Rosa acicularis) plants were collected from three different cutblocks, each sprayed with Visionmax according to […]

Ecosystem Health: Pesticide Use from Forest Management Practices Threatens Essential West Coast Marine Organisms

(Beyond Pesticides, March 11, 2021) A Portland State University (PSU) study finds that pesticides from the forestry industry threaten clams, mussels, oysters (bivalves) along the Oregon state coast. Bivalves are excellent indicator species, signaling environmental contamination through their sedimentary, filter-feeding diet. However, continuous pesticide inputs—from various forestry management regimes—into watersheds along Oregon’s coastal zone endanger these species in downstream rivers and estuaries (river mouths). Although research demonstrates many forestry practices (e.g.., road building, planting, clearcutting, thinning) have cumulative effects on the ecosystem, there is a lack of studies addressing the overall impact of multiple chemical mixtures and application on watersheds and subsequent aquatic transport. Like agriculture, conventional forest management across the U.S. depends on the use of toxic pesticides to control pest populations. However, pesticide residues from application drift, runoff, and contamination continuously jeopardize the health and fitness of various non-target species, including humans. Marine ecosystem pollution is difficult to track and measure, and forestry pesticide regulations can invoke variations in water quality requirements through discrepancies in buffer zones and application concentrations. Therefore, studies like this can help guide future forest management practices to reduce the number of chemicals entering aquatic ecosystems. Researchers in the study note, “These findings highlight the need to […]

Oregon Officials Finalize Restrictions on Bayer’s Tree-Killing Herbicide, Stop Short of a Full Ban

(Beyond Pesticides, May 16, 2019)  Use of the tree-killing herbicide aminocyclopyrachlor (ACP) is now restricted in Oregon, according to rulemaking finalized last week by the state’s department of agriculture (ODA). While an important step in the right direction, many environmentalists are perplexed by the state’s decision not to proceed with a ban on all uses of the inherently toxic chemical, which has killed thousands of old-growth pine trees along state scenic highways. Over five thousand comments from Oregonians and concerned individuals across the country urged ODA to scrap its convoluted proposed rule and simply eliminate the chemical from state commerce. While advocates will continue to urge ODA to completely eliminate ACP use, the current restrictions did not come without a fight. Public meetings were attended by representatives from the chemical’s manufacturer, Bayer. The company strongly opposed any restrictions on its product, and acted to delay the original implementation date for ODA’s rule. Oregon had intended to finalize the rule in late March. “We were pretty much set to file the final paperwork,” said Oregon pesticide program manager Rose Kachadoorian to The Bulletin. But through the work of its corporate lawyers, Bayer was able to track down an arcane Oregon law that […]

Glyphosate Use in Forestry Drifts on Wild, Edible Plants, Leading to Lasting Contamination

(Beyond Pesticides, March 5, 2019) Wild, edible plants subject to drift from the herbicide glyphosate during forestry operations can be contaminated with the chemical an entire year after an initial application, according to a new study published in the Canadian Journal of Forest Research. Glyphosate is often used in forestry to knock down unwanted trees, shrubs, and other plants after clear-cutting to provide room for the regrowth of trees deemed valuable. However, this new research shows that “non-target” species, such as raspberries and blueberries, eaten by wildlife and sometimes wild foraged by humans can retain significant levels of glyphosate contamination due to drift and overspray. Forester Lisa Wood, PhD, from the University of Northern British Columbia began this research based on input and requests from Canadian indigenous First Nations communities. Back in 2013, shrubs foraged by traditional berry-pickers in northeastern British Columbia were sampled and found to contain glyphosate residues, leading to the need for a broader investigation. Dr. Wood sampled the roots and shoots of 10 plant species from an area that had been aerially sprayed with glyphosate a year prior as part of forestry operations to clear aspen and make room for coniferous re-plantings. The 10 plants, which […]
