Tree deaths stump worried owners

TREVOR Dwyer says scientists investigating the health of the Fitzroy River should study the dead trees and other vegetation on land that was flooded last year.

Standing in front of a bank of dead black wattle trees on Ridgelands Rd, Alton Downs, Trevor said he feared the trees proved there was something deadly in the water.

The 71-year-old former refrigeration mechanic said there was evidence throughout the flood zone of trees and plants that failed to recover after the floods.

"I've lived here for nearly 30 years and there have been lots of floods in that time, but vegetation usually recovers," My Dwyer said.

"This time it's different. There are thousands of mangroves along the banks of the river that have died. Brigalow has died too."

Trevor said he feared it wouldn't be long before the wattles simply keeled over into the road.

"It looks just like they've been poisoned and whether it's salt or something else, there should be a proper investigation."

Landowners in Alton Downs and Nerimbera interviewed yesterday confirmed plants were still dying a year after floodwaters subsided.

One said the demise of mangroves was a major concern because mangroves thrived on salt so it couldn't be elevated saline levels that had killed them.

"After every flood mangroves normally recover very quickly. But this time there are no signs of life. It must be a chemical thing," said one landowner.

"It just doesn't add up to me."
