ANY accountant will tell you, 500 trees planted by 29 people, is an average of 17.2 trees per planter.

If you were to ask the accountants at Deloitte however, you would probably get a response more along the lines of 500 trees means hard yakka, face full of flies and whole lot of sweat.

Yesterday, 29 desk jockeys from Deloitte in Brisbane swapped their calculators and laptops for shovels and some heavy duty gloves as they spent the day planting trees at the Gladfield Treehenge site.

While the main concern on most minds was to have the plants in order and mulched correctly, there was something else keeping planters a little on edge.

"Gemma loves the snakes," Deloitte client manager Andrew Stewart joked.

But when the Daily News arrived on site, the snake-sighting count was still at zero - much to the delight of planters, and Gemma.

Mr Stewart said the day was part of their annual Impact Day, where all Deloitte staff stop work for a day to help out a worthy cause.

"It's a little more hands-on than calculators and spreadsheets, but it's a fun experience and a chance for us to give back to the community," he said.

Condamine Alliance CEO Phil McCullough said there were about 40,000 trees in the ground, and another 35,000 trees to go over the next five years.

"The aim is to connect the range with as much bushland as we can by extending the ecosystems," Mr McCullough said. "Once it's all done, it will become a place to do touristy things."
