Weeds ...... destroying our coastal vegetation

A WEED IS ANY PLANT THAT OCCURS WHERE IT DOESN’T BELONG, AND CAN DOMINATE
OR UNBALANCE AN ECOSYSTEM

Fast-growing weeds destroy local native plants by out-growing them, often smothering them and competing for the available water, nutrients and light. By contrast, local native plants often grow more slowly, being adapted to low-nutrient soils. Fast-growing opportunistic weeds may grow and mature within a few weeks, smothering natives, and leaving a residue of seed and dead vegetation that raises nitrogen levels and creates a fire hazard. Weeds from other parts of the world have been introduced without the predators that may have kept them under control in the places from which they came.

The following photos show the most common weeds infesting native bushland along the Joondalup coastline. For further details use the button below to go to the Weeds Gallery ....
