The stunning landscapes of Cape Cod, with their salt marshes and coastal views, are under siege from an invasive plant: Phragmites australis, commonly known as common reed. This aggressive invader has taken over large portions of the Cape’s salt marshes, obstructing breathtaking views, threatening local wildlife, and disrupting the delicate balance of the ecosystem. Recently, a family which has lived along Mill Creek for many years and is deeply connected to this landscape, decided to take action after witnessing the profound impact of Phragmites on their land and the surrounding marshes.
The History of the Project
This project began with a family who has lived along Mill Creek and cherished the coastal beauty of their two properties for many years. However, over the years, the once stunning views were blocked by the rapid and relentless growth of Phragmites. Initially spotted as an unwelcome guest, this invasive reed grew to towering heights of 10 feet, completely obstructing their scenic views and threatening the salt marsh grasses and native species essential for a thriving ecosystem.
Recognizing the urgent need for intervention, the family took a proactive approach to restore not just their views but the health of the surrounding environment. They understood that the proliferation of Phragmites was endangering crucial salt marsh grasses, which play a vital role in supporting wildlife, buffering floodwaters, and providing ecological benefits to the area.
Why Addressing Phragmites Matters
Phragmites pose significant threats to biodiversity. Its aggressive growth outcompetes native vegetation, such as salt marsh grasses, leading to reduced plant diversity and altered habitat conditions for wildlife. This invasive species can choke out plants that provide food and shelter for countless creatures, disrupting the food web and diminishing the richness of the ecosystem.
Removing Phragmites not only protects local biodiversity but also offers substantial ecological services to humans. By restoring native vegetation, the area can enjoy improved stormwater protection, enhanced water quality, and a resurgence of local wildlife populations. The aesthetic and ecological health of the Cape can be revitalized through dedicated efforts to reclaim the landscape.
The Restoration Strategy
CLM has developed a comprehensive approach to tackling this Phragmites population. The restoration strategy involves a systematic process: bundling stalks together, cutting them, , and applying an appropriate herbicide to the cut stalks. This method ensures that up to 90% of the Phragmites population is effectively eliminated. A direct stem application ensures that herbicide only touches the reed itself, and does not enter the surrounding environment.
Timing is critical; treatments are scheduled to coincide with the plant’s energy transfer to its roots, maximizing the herbicide’s efficacy. The goal is to ensure that the herbicide travels down to the root system, effectively killing the plant and preventing it from re-sprouting. Future follow-ups will be minimal, and ongoing maintenance will ensure long-term success in restoring the native landscape.
Fall Work & Next Steps
As we push forward through this crucial fall season, the initial bundle, cut and wipe treatment of the Phragmites will begin. These property owners can expect minor re-sprouting next season, but follow-up maintenance treatments will be more and more minimal each year, and will ensure the reed is effectively controlled. Over the next few years, the resilience of native salt marsh grasses will also be evident. These grasses often return quickly, with growth visible within the first year after treatments, and with proper management, a healthy native salt marsh ecosystem can begin to heal and flourish once again.
The Bigger Picture: A Collective Effort on the Cape
This project is more than just a local endeavor; it symbolizes a collective effort among property owners across the Cape to manage invasive species and restore the natural function of the ecosystem. The removal of Phragmites from these two properties serves as a vital step toward reclaiming not just a single view but improving the overall health of the coastal ecosystem.
As more property owners unite in this effort, the benefits multiply–stormwater protection, enhanced wildlife viewing, cleaner air and water, and the restoration of the stunning landscapes that define Cape Cod. By working together, we can foster a resilient coastal environment for generations to come.
As CLM moves forward with this essential work, we invite the community to join in the restoration efforts. Together, we can reclaim our coastal beauty and ensure that the rich biodiversity of Cape Cod continues to thrive. Let’s take this step towards a healthier, more beautiful world—one that is not just for us, but for all the wildlife and future generations who will cherish it.
