Concerns over the environmental impact of weed control in Bournemouth, Christchurch, and Poole (BCP) have intensified following an independent review that flagged widespread reliance on pesticides and herbicides.
Campaigners and researchers are warning that current practices may be placing rivers, wildlife, and even public health at risk, while the council maintains its methods are both regulated and cost-effective.
Independent Review Raises Alarms
The analysis, conducted by environmental researcher Steve Harper, examined the range of chemicals used by BCP Council in 2024. Of the 51 substances listed, 49 were found to be harmful to aquatic life. According to Harper, the data paints a troubling picture of how weed management intersects with ecological health.
“These substances don’t just eliminate unwanted plants,” Harper said in response to his findings. “They threaten rivers, pollinators, and human health. It is deeply concerning that nearly all of them are toxic to aquatic ecosystems.”
The review was supported by Extinction Rebellion, which has long campaigned against the continued use of pesticides in public areas. The group highlighted a growing body of research showing that when chemicals mix in the environment, they can interact in unpredictable ways, producing what scientists call the “cocktail effect.”
This interaction, campaigners argue, can amplify harmful outcomes even when individual chemicals are considered manageable on their own.
Financial Commitment to Herbicide Use
A Freedom of Information (FOI) request submitted by Pesticide Action Network UK revealed that the council spent £217,552 on herbicide purchase and application in the past year alone.
Critics point to that figure as evidence of heavy reliance on chemical controls at a time when dozens of other towns and cities in the UK are moving away from them.
Across the country, 53 local authorities have either gone pesticide-free or are phasing out chemical weed control altogether. Campaigners argue that BCP’s ongoing use of glyphosate and other products marks it as an outlier, particularly given the increasing adoption of non-chemical methods elsewhere.

Glyphosate at the Heart of Debate
Glyphosate, one of the most commonly applied herbicides in the world, sits at the center of this debate. While it remains approved for use in the UK and internationally, critics argue that its safety record is disputed. Campaigners highlight studies linking glyphosate exposure to risks for pollinators and aquatic species.
On its website, BCP Council describes glyphosate as a “regulated approved herbicide, considered safe to use across the world.” The council insists its weed management programme follows official guidance and is mindful of balancing environmental concerns with the need to maintain public spaces.
Calls for Alternatives and Public Engagement
Harper’s report does more than criticize, it sets out recommendations for a different path forward. Chief among them is the call for councillors to investigate alternative weed control methods that avoid reliance on harmful chemicals.
The report also urges the council to improve public awareness about safe disposal of household pesticides, a factor often overlooked in broader debates about chemical use.
“Other towns and cities across the UK are proving that safer alternatives exist,” Harper said. “BCP must urgently commit to phasing out glyphosate and pesticides in public spaces and adopt more sustainable approaches.”
Suggested options include the trial of mechanical or thermal weed removal, and greater use of mulching techniques to suppress unwanted growth naturally.
Council Response: Balancing Risks and Responsibilities
BCP Council has acknowledged residents’ concerns but defended its current strategy. Kate Langdown, the authority’s director of environment, stressed that the council is committed to gradually reducing chemical use while ensuring public spaces remain well-maintained.
“We recognise the concerns some residents have about the use of chemicals to control weeds and undesirable plant species,” Langdown said. “We’re committed to reducing this, whilst balancing the need to make sure our outdoor spaces in BCP are properly maintained.”
Langdown highlighted glyphosate’s effectiveness and argued that, compared to other available methods, it remains a cost-efficient tool with a relatively low carbon footprint.
“Like many other local authorities, we use glyphosate products as they currently remain the best available solution; the results are long-lasting, cost-effective and have the lowest environmental impact in terms of carbon emissions,” she explained.
The council pointed to steps already taken to scale back chemical use, such as reducing the number of glyphosate treatments on highway land from three to two annually. In addition, it has introduced organic mulching, made from locally sourced compostable material, in shrub borders to help control weeds without chemical intervention.
Langdown added that the authority has trialled various alternatives and remains open to adopting emerging solutions as they prove viable.
A National Shift in Weed Management
The situation in BCP reflects a broader national conversation about the role of pesticides in public land management. Local governments across the UK are grappling with the dual challenge of maintaining clean, safe spaces for residents while responding to mounting environmental concerns.
The move away from glyphosate and similar products in more than 50 towns and cities signals a trend toward precaution and innovation.
Councils have been experimenting with alternatives ranging from foam-based treatments to handheld mechanical tools, each offering varying degrees of effectiveness and cost-efficiency.
Campaigners argue that while such methods may initially demand greater investment, they ultimately align better with public health and environmental goals.
They also note that a proactive approach can shield councils from future liabilities if public attitudes and regulations shift more decisively against chemical controls.
The Tension Between Cost and Ecology
One of the underlying issues is financial. For many councils already under budget pressures, glyphosate’s combination of affordability and effectiveness makes it difficult to replace.
Non-chemical methods often require higher labour costs and more frequent treatments, which can strain already limited resources.
Critics, however, argue that the cost equation should be viewed in the context of long-term environmental damage and potential health implications.
As Harper and Extinction Rebellion point out, short-term savings may be outweighed by the broader costs of biodiversity loss, water pollution, and public health risks.
The Road Ahead for BCP
With the independent review now in the public domain and environmental campaigners increasing pressure, BCP Council faces a pivotal decision about the future of its weed management practices.
The authority has signalled willingness to continue exploring alternatives, but campaigners say stronger commitments are needed to match what other councils have already achieved.
For now, the debate underscores a wider challenge facing local authorities: how to balance the immediate practicalities of weed control with the longer-term imperative of environmental sustainability.
As more data emerges about the ecological impact of pesticides, councils like BCP will likely come under even closer scrutiny from residents, researchers, and national campaign groups.
The controversy has transformed weed management from a routine maintenance issue into a flashpoint for broader discussions about how communities interact with their natural environments.
Whether BCP Council chooses to double down on its current strategy or accelerate the search for alternatives may set an important precedent for other authorities navigating the same dilemma.
