Phragmites. A small plant causing a big problem by saskia diplock

Today i am warning you about Phragmites. I will be telling you about the impacts, efforts to control Phragmites, the classification, characteristics, its habitat, and some facts. There are also websites, videos, and text to show you why you should help keep phragmites under control.


Phragmites grows in stands that can be extremely dense with as many as 200 stems per square metre, and can grow so densely that it crowds out other species. Phragmites can reach heights of up to 5 metres (15 feet), and it has stems that are tan or beige in colour with blue-green leaves and large, dense seedheads.

Native phragmites

Classification: Phragmites are grouped into the kingdom: plantae, Order: Poales, Family: Poaceae, Subfamily: Arundinoideae and the Genus: Phragmites

Invasive Phragmites is an aggressive plant that spreads quickly and out-competes native species for water and nutrients. It releases toxins from its roots into the soil to hinder the growth of and kill surrounding plants. While it prefers areas of standing water, its roots can grow to extreme lengths, allowing it to survive in relatively dry areas.

Invasive Phragmites is an invasive plant causing damage to Ontario’s biodiversity, wetlands and beaches. Invasive Phragmites is a perennial grass that has been damaging ecosystems in Ontario for decades. It is not clear how it was transported to North America from its native home in Eurasia, but it is now Canada's worst invasive species.

Here is a video from Vimeo that shows a little bit more about how Phragmites affects all different people. Right now, Phragmites are a big problem.

Phragmites invades North america, the lower 48 states of the u.s, and Canada. The phragmites natural habitat is Eurasia, usually in ditches, low standing water, and it can survive in dry land as well. (mud, dirt, etc.)

Phragmites are a little plant that can grow and grow, and cause lots of destruction. Some bad impacts that can happen: Phragmites crowds out native vegetation, decreases food supply for wildlife, causes low water levels and increases fire hazards.

A few efforts to control invasive species: Ontario has regulated invasive phragmites as restricted under the invasive species act. They are also profited and restricted to bring into the country. There are plenty of websites that can help stop the growth of phragmites, like the one on t he button below. Thank you for listening to my presentation, and I hope you learned lots more about Phragmites.
