Managing vegetation around utility and renewable energy infrastructure has always been essential, but rising operations and maintenance (O&M) costs, persistent labor constraints and expanding infrastructure portfolios are prompting utilities to take a closer look at how vegetation is managed.
Utilities are facing pressures that are increasingly difficult to address with traditional vegetation control methods alone. Conventional mowing cycles, broad herbicide application and reactive emergency clearing are costly and labor-intensive, and over time, often require additional treatment to keep vegetation under control. At the same time, the amount of land utilities are responsible for managing has expanded rapidly as new transmission, solar and wind infrastructure is deployed across the country. Together, these factors are prompting a reassessment of long-standing vegetation strategies.
Vegetation management represents one of the largest ongoing operational costs for utilities. A multiyear economic analysis of electric and gas utility rights-of-way corridors evaluated the cost of integrated vegetation management (IVM) against traditional approaches that rely on repeated mowing or uniform herbicide treatment. The study concluded that IVM consistently reduced total maintenance costs over time by decreasing the need for recurring mechanical work and establishing and stabilizing compatible vegetation communities. In addition to lowering costs, the approach improves habitat conditions and supports long-term land stewardship outcomes.
Against that backdrop, IVM is moving beyond best practice and moving into more widespread consideration for many organizations.
What IVM Is and Why It Works
The U.S. Environmental Protection Agency defines IVM as the practice of promoting desirable, stable, low-growing plant communities through a balanced combination of biological, chemical, mechanical, manual and cultural controls. When implemented strategically, IVM mitigates the regrowth of incompatible vegetation while improving environmental quality and lowering long-term costs.
Rather than repeatedly cutting vegetation only to watch it regrow, IVM establishes ecosystems that naturally suppress incompatible growth and minimize future interventions.
From Reactive Work to Strategic Management
Traditional vegetation programs operate on fixed cycles that involve repeated mowing and regrowth. Labor crews are dispatched regularly across miles of rights-of-way, and costs escalate with fuel use, equipment wear and crew hours. As field labor becomes more constrained across the industry, utilities are finding this model increasingly difficult to sustain.
IVM breaks that cycle. After an initial transition period, plant communities stabilize around low-growing species that require fewer interventions. The result is a shift from high-frequency fieldwork to management based on long-term vegetation profiles, reducing O&M costs and field exposure.
In a 20-year present value analysis comparing IVM treatment cycles with repeated mechanized mowing, IVM programs consistently resulted in total maintenance costs 25% to 57% lower than mowing alone.
Safer, More Efficient Field Operations
Field crews tasked with vegetation control face real risk. Working near energized infrastructure, navigating challenging terrain and responding to urgent clearing needs all add to the safety risks crews face in the field. Reducing the frequency of these activities through more predictable vegetation conditions can improve overall safety performance.
By reducing routine mechanical visits and emergency calls, especially during peak growth seasons, IVM allows utilities to redirect crews to higher-value work while spending less time in potentially hazardous conditions.
Ecological Value at Scale
Utilities manage tens of millions of acres nationwide, much of it spanning diverse ecosystems and sensitive habitats. At this scale, vegetation strategies directly influence regional habitat quality, stormwater behavior and pollinator health.
IVM programs that integrate native grasses, forbs and pollinator-friendly species such as milkweed help stabilize soil, reduce erosion and deliver ecological benefits beyond right-of-way boundaries. These outcomes align with broader environmental stewardship goals by supporting species of concern and improving biodiversity across managed landscapes.
Community Trust Through Strategic Land Management
Communities increasingly expect utilities to act as responsible land stewards. Vegetation corridors once viewed as overgrown or problematic can become valued landscapes when managed under IVM principles, functioning as pollinator pathways, natural buffers and habitat corridors.
Reduced reliance on broad-spectrum herbicides and visible native plantings also improve perceptions of responsible land use, helping utilities build trust with residents, regulators and other stakeholders.
Renewable Infrastructure Benefits
Vegetation management challenges extend across the broader energy transition. Solar fields, wind turbine corridors and battery energy storage system sites contend with shading, access hazards and stormwater management, increasing the need for vegetation strategies that are safe, predictable and cost-effective.
IVM helps mitigate shading risk around solar arrays, enhances stormwater infiltration and reduces long-term maintenance demands. At wind facilities, stable vegetation improves access for inspection and reduces erosion around towers and foundations.
A Strategic Infrastructure Tool, Not a Tactic
IVM is more than an alternative technique. It is a proven infrastructure stewardship strategy that delivers measurable value over time. By elevating vegetation management from tactical mowing to strategic ecosystem management, utilities and energy developers can reduce costs, improve reliability and strengthen community relationships amid rising O&M pressures and constrained labor resources.
For organizations evaluating vegetation strategies, a tailored IVM program designed to align with operational needs and sustainability objectives offers a scalable path going forward.
