PIALBA'S Tooan Tooan Creek was a hive of activity on Sunday as volunteers took part in National Tree Day.
Councillor George Seymour said more than 1500 shrubs and grasses were planted on the Hillyard St side of the creek.
It was the second year in a row tree day had been held at Tooan Tooan Creek.
"Two years ago this area was a dump ... and it was very barren," Cr Seymour said.
"The difference already is incredible. I'm very proud of it."
National Tree Day is Australia's largest tree-planting event and has seen more than 18.6 million native trees, shrubs and grasses planted since it was launched in 1996.
This year marked the planting of the 20 millionth seedling.
