Parks Victoria has found several illegally felled trees at Jeparit, Lake Hindmarsh Lake Reserve and Wimmera River Heritage Area Park.
Parks Victoria area chief ranger Lisa Freeman said there was a history of illegal tree felling in the areas, with 11 trees in the latest count.
“It is illegal to cut down and remove trees from public land without authorisation,” she said.
“Many illegally felled trees are more than 100 years old, which means they won’t be replaced in our lifetime, or even the next generation.”
