An investigation is underway after a tree that was hundreds of years old was chopped down, cut into pieces and stolen from a national park near Collie.

Department of Parks and Wildlife district manager Drew Griffiths said a group entered the Greater Preston National Park 25km south east of Collie and removed the large jarrah tree over the weekend between Christmas and New Year.

"They felled it, dragged it along the ground, sawed it up and took chunks of timber from it and in doing so damaged other native vegetation, all of which is an offence."

Nearby resident Greg Hall provided the Collie Mail with pictures he snapped after discovering the site that weekend.
