The Shire of Collie is investigating why a number of peppermint trees have died in town after several reports from concerned Collie community members.
Quite a number of trees near the railway track located behind the petrol station, McDonalds, the Collie Art Gallery and the Bendigo Bank Music Shell have died or are looking unwell.
Collie resident Dennis True said he noticed one or two trees started to look sick last year.
"A couple of months ago I was looking outside the Premier Hotel window and it seemed like a few more were in trouble," he said.
"The one closest to the Collie Art Gallery behind the service station was turning its toes up, and subsequently, it has died.
"So I went for a walk around in that area and found a lot more of trees were in distress. I counted roughly 11 that were either dead or dying."
Mr True said it seemed odd that a high portion of them had run into some problems.
"They're peppermint trees which are quite hard to kill," he said.
"Similar trees in Central Park and further down near the footbridge seem to be okay."
Mr True he would just like to know the reason as to why they were dead and dying.
"I know there have been some considerable drainage works in that area to try and eliminate the problem on the drainage near the Premier Hotel, after they have often had flooding," he said.
"It could be that the drainage works could have effected the water table, or it could just be climate change, or they could have been poisoned.
"I would just like to know why."
Shire of Collie chief executive officer David Blurton said he has seen the trees and because that land was part of shire reserve they would be looking into it.
"I don't know what's really going on there, but we will be doing an analysis into it," he said.
Mr Blurton said that shire staff do not currently water the trees because they were big enough to maintain themselves.
