Battling Invasive Plants: A Success Story

In the breathtaking landscapes of the Boise and Sawtooth National Forests, which collectively span over 4.4 million acres, our team recently embarked on an ambitious and meaningful initiative: the Boise & Sawtooth Forest-wide Invasive Plant Species Treatments project. The aim was clear – mitigating the harmful effects of invasive plants on the integrity and operation of local ecosystems and preserving these incredible spaces for future generations to admire and enjoy.

The Threat of Invasive Plants

When it comes to preserving the delicate balance of our ecosystems, invasive plants have emerged as a formidable foe. These aggressive plant species pose a significant threat to the health and stability of native ecosystems. With their ability to outcompete native flora, disrupt habitats, and destabilize the intricate balance of the environment, their impact is far from benign. In our dedication to conserving biodiversity, we set out on a mission to counteract the influence of these unwelcome botanical invaders in the heart of the Boise and Sawtooth National Forests.

Invasive plants such as cheatgrass and medusahead have been wreaking havoc on native ecosystems. Cheatgrass (Bromus tectorum) can rapidly dominate a landscape and change the fire regime, making the area more susceptible to fire and preventing native plants from recovering. Medusahead (Taeniatherum caput-medusae) is another aggressive invader that outcompetes native vegetation for resources, reduces wildlife habitat, and poses a significant threat to rangeland productivity. These invasive species not only displace native flora but also significantly alter the functions of the ecosystems they invade, leading to a decline in biodiversity and habitat quality.

Medusahead is common through much of southwestern Idaho region and is common in burned and unburned sagebrush and in some places co-exists with a diversity of other species (especially with other invasive plants such as cheatgrass).

Specific Tasks and Outcomes

The main objective of this ambitious project was to minimize the harmful effects of existing and potential invasive plants on the native plant communities and other natural resources within the Boise and Sawtooth National Forests. Invasive plants have the ability to rapidly colonize new areas, outcompete native species, and alter the landscape’s ecological balance.

We employed a range of strategies in our efforts to identify and treat existing weed infestations across these vast National Forests, placing a priority on those posing the highest severity and risk. The project focused on improving sagebrush obligate habitats and managing invasive species through a combination of preventative measures, removal techniques, and containment strategies. We also sought to prevent the introduction and establishment of particular weed species, chiefly in areas identified as high risk due to recent wildfire incidents.

Interdisciplinary Team Meetings

To complete this project, the Forest Service sought the expertise of Peak Science Communications (PSC) to complement the Forest Service interdisciplinary team (IDT) and enhance the project’s effectiveness. The success of this project can be attributed to the close working relationship between PSC and the IDT.

PSC attended and meticulously documented all IDT meetings. These gatherings served as a crucial platform for collaboration and knowledge-sharing among experts from various fields, ensuring a well-rounded approach to combating invasive plants.

Recreation Specialist

Recognizing the significance of preserving recreational resources, the project enlisted a recreation specialist that was employed by PSC. This expert played a pivotal role in writing the recreation resource report, addressing the appropriate use of herbicides in designated Wilderness areas, and striking a harmonious balance between recreation and conservation.

Technical Reports

The Forest Service wrote numerous technical reports which PSC edited and formatted to be compliant with accessibility laws. From human health to wildlife, each report provided valuable insights into the potential effects of the proposed actions, laying the foundation for informed decision-making.

Environmental Impact Statement and Record of Decision

PSC wrote a comprehensive Environmental Impact Statement (EIS). The 495-page EIS disclosed the direct, indirect, and cumulative effects of the proposed actions, offering a thorough assessment of the project’s potential outcomes. Additionally, PSC prepared and meticulously edited the Record of Decision (ROD) to provide a clear roadmap for the project’s implementation.

Content Analysis

The PSC team diligently analyzed public comments to identify pertinent issues and concerns raised by stakeholders. Incorporating this feedback, they modified the proposed actions to reflect the community’s values and priorities.

Project Record Management

Keeping an immaculate administrative record was essential for the project’s transparency and accountability. The PSC team ensured that the project record met the stringent requirements of the Forest Service Planning Appeals and Litigation System database, providing a comprehensive documentation of the entire undertaking.


The fight against invasive plants is a necessary endeavor, and projects like this one on the Boise and Sawtooth National Forests demonstrate how strategic planning, public participation, and expert involvement can pave the way for more sustainable natural landscapes.

Despite the challenges presented in combatting invasive plants on such a grand scale, our team’s collaboration, expertise, and unwavering commitment to preserving our natural environments fostered a significant advancement in ecological conservation. As we progress, we aim to continue evolving our strategies to maintain our forests’ resilience against invasive plant incursions.

In the end, the responsibility to protect these delicate and invaluable ecosystems falls on all of us. United in our efforts, we can all make a lasting difference in the fight against invasive plants.
