The Stewart Karri Tree/Record Brook

Record Brook Valley is a priceless time capsule.

The data collected and analysed so far provides

evidence of a unique and rare micro environment

we need to preserve in its entirety.

I initiated Record Brook Valley Stewart Karri Tree research project in August 2020 with the purpose of recording and preserving information on the flora fauna and fungi in this precious place.

In the first year of Research the data collected and analysed provides evidence of what is in this flourishing rare ecosystem with its PreJurrasic links.

Record Brook Valley is in the Southern Forest of Western Australia 20 kilometers from the town of Manjimup. It has its own intact water source, Record Brook, fed mainly from underground springs with water uncontaminated by salt and farm runoff.

This Gondwanna Remnant Ecosystem contains plants, fungi and animals who have survived here since life began. Today they live alongside rare and endangered Marsupials.

Towering over it all is Macro Flora, in the form of The Stewart Tree.

The Stewart Tree at 85 meters is the tallest Karri tree in the world and estimated to be 350 years old. Further study of the relationship of this large tree with the fungi in its ancient ecosystem could unlock the secrets of increasing growth in Karri trees.

Environmental Scientist Jenny Carley's offer of assistance in identifying fauna responsible for the diggings in the research area culminated in her photo of a Quokka at the base of the Stewart Tree confirming an online park would have one more star attraction.

View the highlights of the weekly data collection trips over the last year and a half to see the extraordinary range of life this strange miniature world holds.

The Stewart Tree

The Stewart Karri Tree at 85 meters is the tallest Karri in the world & estimated as 350 years old. Located near the town of Manjimup in the South West of Western Australia in Record Brook Valley.

The tree was named after Don Stewart. He developed the idea to use massive Karri trees as fire watchtowers in the 1930's.

This warning system was in use for 50 years and saved many lives.

Eventually spotter planes took over from the fire watch towers. Those few that remain are tourist magnets in the South West.

The Stewart Tree has been undisturbed during most of its 350 years except for occasional visits by intrepid travellers and curious timber workers who ventured in.

Currently Record Brook Valley and The Stewart Tree with its surrounding grove, carpeted with miniature flowers, ancient life forms and rare marsupials looks to have escaped the threat of being flooded by a private water trading scheme The SFIS, Southern Forest Irrigation Scheme.
