The first stage of the project is perhaps the most complex: finding the best ways to eradicate Phragmites.<\/p>\n
Invasive Phragmites: A Formidable Enemy<\/h2>\n
Phragmites are a prime example of invasive species. These plants, which look like tall reeds, have no natural competitors in Canada, so there is nothing to keep them in check. Their populations currently run rampant in Ontario, forming large, dense monocultures where nothing else can grow.<\/p>\n

They seem like part of the natural landscape, but in reality they are actively destroying it<\/strong>.<\/p>\n You can get a good view of large phragmites populations as you drive along the local highways. In fact, the reed grasses have the potential to become a safety\u00a0hazard if left uncontrolled. They can grow so high (up to 16 feet or five meters tall) that they can impede sight lines, and they can expand so much as to clog storm culverts and drainage ditches<\/strong>, which could lead to road flooding if left unchecked. To ensure road safety, the 407 ETR Highway Operations team maintains all the vegetation along Highway 407 ETR.<\/p>\n But there’s something even more alarming happening below the ground.<\/p>\n The species has an extremely dense root system that can be several feet thick. (Take a moment to think about that!) The roots are packed so tightly together that they form a mat, preventing other plant species from growing <\/strong>and inhibiting already existing plants from getting nutrients from the soil.<\/p>\n And plants aren\u2019t the only ones that are affected. Phragmites have a devastating impact on ecosystems, from degrading the quality of the soil to destroying many animals\u2019 natural habitats.<\/p>\n Phragmites\u2019 extensive root network also makes it very difficult to get rid of them. All the roots have to be completely cleared; if you only mow the stems that are visible above ground, new plants can grow again.<\/p>\n The species also spreads very quickly. Highways are ideal place for invasive phragmites populations to flourish and reproduce as the bordering drainage ditches provide the perfect channel for root systems to grow and pathways for seeds to spread.<\/p>\n Seeds can also spread through wind, or by hitching a ride. They stick to vehicle tires and equipment and get carried off to a new location, where they can fall onto the ground and start colonizing new areas.<\/p>\n 407 ETR has launched the 407 ETR Highway Corridor Biodiversity Pilot Project<\/strong> in partner with St. Williams Nursery and Ecology Centre. We\u2019re making it our mission to help restore the natural habitats<\/strong> that have been taken over by invasive species.<\/p>\n The first step of the project is to eradicate the phragmites<\/strong>. We\u2019re investigating a number of different techniques and working together with experts to weigh the pros and cons of each method.<\/p>\n We have selected four different locations along the highway where phragmites grow for the pilot project. One area is already partially restored, the second is an urban area, third is a wild, overgrown walking path, and the fourth and largest location is a wetland. We want to try the techniques in different environments to see what works best.<\/strong><\/p>\n This is the starting point of a long-term project that will take place over several years.<\/p>\n Once we\u2019re able to control the phragmites, we will replace them with native plant communities that will better resist the establishment and spread of the invasive species.<\/p>\n This will help to protect and enhance local biodiversity in terms of both plant and animal species, for a healthier, more sustainable natural environment.<\/p>\n At 407 ETR, we can only control the invasive species within our fence line and Rights of Way. Because of the invasive phragmites\u2019 astounding ability to spread quickly and aggressively, we have to collaborate with partners on the other side of the fence to help control invasive species.<\/p>\n Otherwise, they\u2019re just going to keep coming back.<\/p>\n We\u2019re currently working to establish a voluntary committee with a number of different wildlife and nature conservation organizations. Our goal is to share knowledge from inside the fence and beyond the fence as our investigations and understanding progress and evolve.<\/p>\n We can only be successful fighting invasive species if we address the issue from all possible angles. By learning together and working together, we can help to restore the healthy natural habitats our planet needs.<\/p>\n An article by Abbigayle Weber<\/em><\/p>\n","protected":false},"excerpt":{"rendered":" Usually, road interconnectivity is a good thing.
