History of Black Willow in Australia

The Black Willow tree is native to eastern Canada and the USA. It was first introduced to Australia in the 1960’s as a way to stabilise soils along riverbanks.

This function was short lived. It is believed that over the long term, Black Willow tree has led to increased erosion and has redirected the path of rivers.

It propagates by seed and from plant parts that drop or break away and then travel vast distances along rivers and waterways.

Black Willow Tree Removal and Pruning Permit

Despite the economic and environmental cost of Black Willow, all tree work is regulated by local council, and you may still need a permit.

However, most LGA’s have an exempt tree species list. This is true for many Sydney LGA’s, you may not need a council permit for Black Willow tree removal and pruning.

Mistaken Identity

It is important to get an accurate tree identification. There are many trees that have native look-a-likes. You may be liable for heavy fines if you damage a protected tree.

Even when you have correctly identified your tree, your local council may demand that you provide proof at a later date. Some LGA’s want to see an Arborist report that documents the tree species and condition of the tree.

For best practice, we recommend that you have an expert identify your tree. When you book a site visit, our qualified arborist will inspect your tree and be able to help you identify the species.
