Discarded Christmas trees used to restore creeks and streams, protect fish in Halton
Trees rebuild banks in creeks, streams in order to reduce warming of the water
Although the holidays are over, Conservation Halton is just beginning to stockpile hundreds of Christmas trees.
They're an important resource for restoration efforts in the region, with the conservation authority using the discarded trees to narrow over widened creeks and streams and, in turn, protect local wildlife
"With an over-widened creek, we have a greater surface area for the sun to warm up the water, and when this water is very, very warm, it's not habitable to sensitive species," said Kent Rundle, watershed stewardship co-ordinator with Conservation Halton.

"I'm not entirely sure how the concept came to be, but my guess would be imitating natural processes," Rundle said.
"Trees fall down into the creek all the time. They deflect flows and probably they were saying, 'Wow, sediment is naturally depositing here. We can mimic this.'"
