ULTRA runner Kieron Douglass is keen to expand his conservation efforts after a 100 kilometre tree-planting run on the weekend.
The massive effort - dubbed the 100 Project - saw Douglass planting 100 trees and plants while running as many kilometres around Scribbly Gum Conservation Park in Alexandra Hills.
Douglass said he had run from 7am to 9.30pm to complete 10 loops of 10 kilometres each, some of which he ran in the dark.
The park had a special place in his heart, with Douglass having grown up running its trails.
"I didn't time my run - it was just good to be present in the moment and take it all in," he said.
"I'm used to racing on the trails so this run had a different feel to it.
"It wasn't my fastest run but ... it was a rewarding one.
"I may never see these beautiful gums grow to reach their full potential in my lifetime, but (it) wasn't about me.
"It was about planting for the future ... not only for the next generation to enjoy but for the generation after that and so on (and) more importantly, for our local wildlife that thrives here on the Redlands Coast to which I saw plenty of (on the run)."
Douglass said he had already noticed the difference the newly-planted trees had made to the park's wildlife.
"I've been going back every day to water them and a koala's eaten all the gum leaves off one of the trees," he said.
The run had turned into a larger project to revitalise the conservation park over the next year.
Douglass said he hoped to expand the 100 Project in the coming years.
"I'd love to turn it into an ongoing thing, all through Scribbly," he said.
"It's good to be doing something to benefit my hometown.
"Hopefully next year we can get a few more people involved, maybe make it a community event.
"I had my kids there as well. It was really nice to get them involved. They each planted a tree."
Friends, family and community members turned out to support Douglass, with others expressing their admiration on social media.
"Some people said it was a long time since they'd seen a koala in Scribbly Gum," Douglass said.
"Anything that can help the bush out, the public is all behind it."
Douglass plans to document the conservation efforts in a YouTube series.
