Walton Bridge scour planted


Thanks to BCC Habitat Brisbane and contractors Brisbane Bushcare, a large low-lying area of Walton Bridge Reserve has been planted with native species.

The area adjoining the Rita Huggins Monument on the east side of the creek has repeatedly scoured in flooding in 2011, 2013 and 2023 in both February and May. It was previously mown grass.

Leader of the Walton Bridge Habitat Brisbane bushcare site, Anne Jones, said the area needed to be planted with suitable native species to avoid future scouring.

“It was a shame to lose a grassy area in the park but it had become unstable and difficult to manage.

“While there was the threat of another La Niña over last summer, Habitat Brisbane decided to wait until 2023 to plant.

“As it turns out there was considerable natural regeneration while we waited. Two mature Black Beans Castanospermum australe on either side of the zone dropped their beans and large numbers propagated in the area along with other local species.

“The Brisbane Bushcare crew did a great job clearing the weeds from around the native plants. Then they planted 2000 plants mostly grasses including Bladey Grass Imperata cylindrica in areas which had been infilled with sand,” Anne said.

Javier Lopez from Brisbane Bushcare said we were lucky to have the Black Beans propagating so readily in the area.

Anne said the group was hopeful that the planting would get a chance to mature before another flood.

“The presence of Walton Bridge and the footbridge means the floodwaters gain velocity and height in the narrow zone. Once they are established, native plants should be better able to withstand future floods,” Anne said.

The new planting includes a track for park users and volunteers to still access the creek and enjoy this beautiful area in Walton Bridge Reserve.
