Suppliers of high-impact landscape trees.

Karignan Plantation - Industry leader - giving trees the space they need to thrive

Meet Trees Impact


Trees Impact is Australia’s only dedicated big-tree grower. We were established in 1993 to produce and supply super-advanced and semi-mature landscape trees to the standard needed for trees in public spaces. Our trees are quality controlled to comply with Australian Standard AS 2303:2018 – now accepted as the Australian benchmark. They now adorn projects from South Australia to Central Queensland and all points in between.

We are a compact and highly specialised business. All components are owner-operated and, because our extensive skills and experience are so focused, we are widely acknowledged amongst senior arborists as the ‘standard bearers’ when big trees are needed and only the best will do.
