Last year Cattai Hills Environment Network (CHEN) volunteers sampled for platypus DNA using a new innovation technology called environmental DNA (eDNA) across the Cattai and Little Cattai Creek catchments. We got back 9 positive results out of the 18 sites that were tested! A very exciting result.
This year, in June 2021, CHEN got the opportunity to work with Sydney Water and Western Sydney University (WSU), to sample double the amount of sites across the catchments, 36 sites…
With the help of a group of community volunteers, and Dr. Michelle Ryan from WSU, we sampled our waterways for platypus DNA.
These results will give us a great idea of how platypus are using the waterways across these catchments. This is very exciting stuff and when we do get back these results CHEN has a Platypus Landcare group that is waiting to help restore and look after these platypus key sites.
If you live in the Hills Shire and would like to get involved with CHEN or Platypus Landcare, please email firstname.lastname@example.org for more information.

Australia has over 700 species of eucalypts but did you know we have our very own species of eucalypt found only in the Cattai catchment, called Eucalyptus species Cattai. The species is very rare and has been listed under New South Wales and Commonwealth environmental legislation as Critically Endangered as it is facing an extremely high risk of extinction.
It has been recorded in Glenorie, Annangrove, Kenthurst, Glenhaven and Kellyville.
It is a small, mallee-form tree that can grow up to 4.5 m with thick, furrowed and fibrous bark. Adult leaves are dark green and glossy, and paler on the underside. It can grow individually or in small clustered groups usually around sandstone ridgetops in scrub, heath or low woodland.
Some of its threats are clearing, urban development and altered fire-regimes. Fire is essential for seed germination.
I recently visited for the first time, the Eucalyptus species Cattai population in Heath Road, North Kellyville. At this location there are a number of trees growing along the ridgetop in a pocket of bushland close to urban development.
One of CHEN’s goals is to increase awareness in the local community of this rare and unique species and to aid its protection.
