Typha Success at Attadale Swan River Foreshore

Back in November 2014, Envirapest embarked on a project with the Swan Estuary Reserves Action Group to rid the Swan River foreshore at Tompkins Park, Attadale of the noxious water weed Typha.

Typha Orientalis – is an emergent perennial herb (that looks like reeds) that grows up to 2.4m high. It is prevalent in wet areas, permanent wetlands and irrigation channels. It can be difficult to get rid off because of its prolific seed production and huge root systems. Because this plant thrives in water it can be difficult to ensure the plant absorbs enough herbicide to kill it because up to a third of the plant can be under water. It chokes out native plants and grows so tall it was blocking out the river view from the park.

We had to be especially careful of the product we used to ensure it was safe for Swan River, and native plants and animals. Mark spent days spot treating the Typha, in his wellington boots! We wanted to ensure that the surrounding environment and delicate ecosystem was not damaged.

After a few months, the Typha died off and the area was slashed, resulting in the view being restored. We are extremely happy with the results and with our ongoing weed management plan, we are planning on keeping the Attadale foreshore Typha free for years to come. Below are some before and after photographs of the project.
