Teamwork has resulted in two new woodlands being planted near Dorchester.
The Environment Agency, the Woodland Trust and landowners got together to plant more than 3,400 trees on the Frome and Piddle rivers catchments.
The woodlands will form a feature of the Dorset landscape, improve water quality and reduce flood risk.
The woodlands, each covering approximately one hectare, have been planted at the Came Estate and at Lower Burton Mill.
Species include alder, willow, oak, field maple, wild cherry, hazel, hawthorn and dog rose.
The project cost just over £9,000 to include the cost of the trees and fencing plus two training events when advisors from organisations including Dorset Wildlife Trust received instruction in the importance of trees in river valleys.
Kim Goonesekera from the Environment Agency said: “We are very pleased to have worked with the Woodland Trust and local landowners on this exciting project and look forward to seeing these two areas of woodland grow and play a vital role improving and supporting the surrounding river system and countryside.”
Hamish Thomson of the Woodland Trust said: “Trees help our natural landscape in so many ways.
“I have seen first hand how landowners in the south west have benefited from them.
“The trees planted in partnership with the Environment Agency will hopefully demonstrate how in the long term trees can help reduce flood risk and improve water quality.”
There are plans to extend the project to the Hampshire Avon.
