Salinity profile for the Yass River catchment

YAN recently won a contract to undertake water quality testing which will contribute towards developing a salinity profile for the Yass River catchment. Throughout this project we are working under the direction of Andrew Woolridge from NSW Department of Planning and Environment.
 
This week's water samples were collected from the following waterways: Derringullen, Bowning, Washpen, Woolgaro, Limestone, Gallop, Bango, Mantons, Murrumbateman, Dicks and Hickeys Creeks. These waterways cross Black Range Road several times, move through Bowning, Bango, Manton and Murrumbateman localities.
 
Our water collection officer Debra Butt either had an easy task of collecting a water sample from water flowing over the roadway or she had the other extreme of having to navigate densely vegetated creek banks to collect that important water sample.
 
The above, small but important waterways reflect the level of salinity in the landscape and regular monitoring will enable specialist staff from DPE to develop future management strategies to either maintain or reduce salinity across the Yass Valley.
 
 
 
 

Key’s Matchstick Grasshopper found in Murrumbateman

A rare and unusual grasshopper has been found on a crown reserve known locally as the Murrumbateman Village Grassy Woodland that is being managed for environmental protection by Murrumbateman Landcare Group.

Keyacris scurra is the scientific name for Key’s Matchstick Grasshopper – a species listed as endangered under the NSW Biodiversity Conservation Act 2016.  Professor Michael Kearney (Uni of Melbourne) visited Murrumbateman last weekend and found groups of the rare grasshopper on the reserve.

Key’s matchstick grasshopper is a small insect with a distinctly elongated body shape and no wings. They are mostly brown in colour but may also be green. Length for males is up to 15mm and females up to 25mm. The grasshopper has an annual lifespan hatching in mid-summer, mature by autumn to mate in early spring before laying eggs in the ground and dying off in late spring.

Natural grasslands and grassy woodlands are the preferred habitat. Most of these ecosystems have been lost since European settlement in Australia and these fragmented and scattered habitats have contributed to the decline of this species.

The Murrumbateman reserve is a critically endangered ecological community a remnant of Box Gum Grassy Woodland containing native grasses where the grasshoppers live and shelter and favourite native food sources - the Common Everlasting Daisy Chrysocephalum apiculatum and Sheep’s burr Acaena ovina.

Fascinating Fungi with Alison Pouliot

Alison Pouliot is an ecologist, writer and photographer who specialises in fungi. She led a touch, sight and smell fungi learning experience at a Biodiversity Conservation Trust and YAN funded workshop near Murrumbateman on 15 May.

Alison displayed a comprehensive range of fungi which was collected from this region especially for the workshop. (All fresh fungi was disposed of at the end of the workshop because Alison told us that as the fungi deteriorated a bacterial smell is generated thus reducing its role as a smelling experience for future workshops).

There are twelve criteria to assess when attempting to classify fungi as there are a lot of dangerous look alikes to edible fungi. Alison's latest book 'Wild Mushrooming' clearly outlines the common edible species and their dangerous doppelgangers. 

Fungi creates vital underground networks and their presence reflects the health of a site.  So next time you walk through an undisturbed site look out for those small brown, white or yellow or not so small colourful fungi.
