Karri forest

[1] Karri forest occurs only in the south-west corner of the Southwest Botanical Province of Western Australia, in the Warren biogeographic region.

Small settlements such as Karridale, Deanmill and Pemberton were established around timber mills, and have since become centres for regional tourism.

Following campaigning by environmentalists and others the WA government ended the logging of 2 million hectares of native forests, including Karri, in 2024.

[3] Karri forest is found on loamy soils, but may include wetlands, river edges, heathland and rocky outcrops.

[4] Leaf litter (i.e. twigs, leaves and branches which fall from trees to the ground) plays a substantial role in nutrient recycling and has been measured at 9.45 tonnes per hectare in mature forest.
