Managing Invasive Vegetation with Science
Invasive Vegetation Management Services
Invasive plant species pose a significant threat to the ecological balance and functional health of natural areas. When left unmanaged, they can quickly dominate landscapes, outcompeting native vegetation, altering hydrology, and impairing habitat quality. At EnviroScience, we provide science-driven invasive vegetation management services designed to help clients maintain regulatory compliance, improve site conditions, and protect their long-term environmental investments.
From utility corridors and municipal properties to mitigation sites, preserves, reservations, and other sensitive habitats, our biologist-led teams are highly experienced in distinguishing native from invasive vegetation, a critical skill when developing safe, effective control plans.
This expertise is especially important when threatened or endangered species or their habitat are present. Our clients—government agencies, private landowners, and land trusts—trust EnviroScience to deliver nuanced management approaches that achieve control while safeguarding sensitive ecological resources.
Integrated Approaches for Lasting Results
Our services begin with detailed vegetation assessments and mapping of invasive species to ensure that every management strategy is grounded in accurate field data. Accurate plant identification allows us to target invasive species precisely, minimizing non-target impacts and protecting valuable native plants and sensitive species. We employ a range of mechanical and herbicide-based techniques based on best practices and current research. By integrating manual removal, foliar spray, basal bark, cut stump, and hack-and-squirt treatments, we maximize effectiveness while minimizing off-target impacts.
Our staff comprises certified pesticide applicators, trained ecologists, and experienced field biologists who collaborate to tailor management plans to each site. We rely on EPA-approved herbicides and selective application methods, ensuring safe and compliant treatments even in habitats where rare, threatened, or endangered species occur. When applicable, we incorporate native vegetation restoration and follow-up monitoring to track progress and document treatment efficacy.
Supporting Regulatory Compliance and Restoration Goals
Invasive vegetation management is often a required component of long-term ecological restoration and mitigation success. EnviroScience helps clients meet regulatory obligations tied to wetland permitting, stream mitigation, and post-construction monitoring. We’re frequently contracted to manage invasive species as part of:
- Clean Water Act Section 404 permit compliance
- Mitigation banking success criteria
- Habitat restoration grant deliverables
- Utility and transportation right-of-way maintenance
We maintain detailed records and provide photo documentation, GPS-referenced treatment areas, and summary reports to support your agency reporting or grant requirements. Our technical expertise in sensitive habitats sets us apart—we understand the stakes when listed species are involved, and we design management plans to protect these resources while achieving the necessary level of invasive vegetation control.
Field-Tested Expertise, Season After Season
Invasive plant growth and treatment windows vary seasonally. Our crews are trained to identify priority species during different phenological stages and deploy the appropriate treatment methods year-round. This field experience allows us to recognize species accurately even at different life stages, ensuring selective treatments that protect native biodiversity and T&E species habitat. This flexibility allows us to adapt to site conditions and apply proactive strategies that prevent recolonization and reduce long-term costs.
We also specialize in multi-year management plans for larger properties and organizations with ongoing stewardship responsibilities. Our work across the Midwest and Eastern U.S. has helped protect thousands of acres of wetland, forest, prairie, and riparian habitat.
Let’s Build a Better Landscape Together
Whether you’re restoring a stream, maintaining a conservation easement, or simply looking to improve native plant diversity on your property, we’re ready to help. With EnviroScience, you gain a partner who understands both the science of invasive vegetation management and the responsibility of working safely in habitats that support threatened and endangered species. Learn how our selective, science-based Invasive Vegetation Management Services can support your goals and create lasting results for your site.
Few environmental firms in the country retain EnviroScience’s degree of scientific know-how, talent, and capability under one roof. The diverse backgrounds of our biologists, environmental engineers, scientists, and divers enable us to provide comprehensive in-house services and an integrated approach to solving environmental challenges—saving clients time, reducing costs, and ensuring high-quality results.
Our client guarantee is to provide “Excellence in Any Environment,” meaning no matter what we do, we will deliver on our Core Values of respect, client advocacy, quality work, accountability, teamwork, and safety. EnviroScience was created with the concept that we could solve complex problems by empowering great people. This concept still holds true today as our scientists explore the latest environmental legislation and regulations and incorporate the most up-to-date technology to gather and report data.
EnviroScience expertise includes but is not limited to aquatic surveys (including macroinvertebrate surveys and biological assessments); ecological restoration; ecological services (including impact assessments, invasive species control, and water quality monitoring); emergency response; engineering and compliance services; endangered mussel surveys; laboratory and analysis; stormwater management; sustainability services; threatened and endangered species; and wetlands and streams (including delineation and mitigation). Further, EnviroScience is one of the few biological firms in the country that is a general member of the Association of Diving Contractors International (ADCI) and offers full-service commercial diving services.

EnviroScience’s malacologists are U.S. Fish and Wildlife Service-approved surveyors and are well-versed in state-specific permitting procedures. With decades of combined experience and close relationships with regulatory agencies, our team offers streamlined, compliant mussel survey services across the Midwest and Appalachia. We specialize in:
Liesel’s leadership and technical expertise reflect the caliber of EnviroScience’s nationally recognized malacology services. Whether your project is in the early planning phase or approaching construction, our freshwater mussel survey team can provide the data and regulatory support needed for successful permitting.
A Toxicity Identification Evaluation (TIE) is a structured, EPA-approved methodology used to determine the specific toxicants responsible for observed toxicity in effluents. Once the suspected source of toxicity is known, a Toxicity Reduction Evaluation (TRE) implements corrective actions to mitigate or eliminate these toxicants—ensuring regulatory compliance and long-term environmental sustainability.
WET testing is a key requirement under the Clean Water Act and NPDES permitting. Regulatory agencies may mandate a TIE/TRE investigation to restore compliance when toxicity is detected in effluent discharges. Without timely resolution, your organization may face:
