Filming Invasive Phragmites Removal in Marshlands
Big props to the technicians who work on invasive species in demanding environments. The days are long and the sun is relentless in vast, open marshlands.
This week I returned to a giant marshland where I did a filmmaking assignment several years ago paddling deep into this marshland. At that time this marsh was infested with Phragmites, a brutal invasive grass species that chokes out habitat and makes it impossible for many species to even navigate though the marsh. Paddling low in a canoe, the Phragmites was so tall and dense, I needed to use GPS to find the open route back to where I started.
When I returned to this marsh this week, the invasive species team from Giles Restoration launched two bush master all-terrain marsh vehicles to do yet another followup on removal of Phragmites from this area. The results have been extremely successful. Filming included on the bush master, and on-the-ground interviews and broll. To reach the vehicles and the team deep in the marsh, a drone was deployed to capture the team at work.
The spread of Phragmites australis poses a significant threat to wetlands and marshes across many parts of the world. This invasive species aggressively outcompetes native vegetation, creating dense monocultures that drastically alter the natural habitat. Its tall, thick stalks block sunlight from reaching other plants, reducing biodiversity and disrupting the ecosystem balance. Native species, including important wetland flora and fauna, struggle to survive in areas dominated by Phragmites, leading to a decline in plant diversity, which in turn impacts birds, amphibians, and insects that depend on these ecosystems for food and shelter.
In addition to its ecological impacts, Phragmites also alters the physical characteristics of wetlands. Its extensive root system can change water flow patterns, raising soil elevation and turning once-healthy wetlands into drier, less functional areas. This transformation reduces the wetlands’ ability to filter pollutants, manage floods, and sequester carbon, diminishing their value as crucial environmental buffers. Efforts to control Phragmites invasions are often expensive and labor-intensive, requiring long-term management to prevent regrowth and further spread. Without effective intervention, the unchecked spread of this invasive species could lead to the permanent loss of vital wetland ecosystems.
