We have all been involved in Melbourne Water's the Stream Frontage Program, which provides funding to get rid of weeds and plant native vegetation, though the stream sides often have plenty of seed and small plants hiding under the weeds (blackberry and gorse) that come back when spraying knocks these off.
What a change! The Red Hot Pokers on the Blairs need another round of discouragement, as do the blackberries on Vicki's place, next along the creek. But the Best's place is a delight, and the section from Ross's to Stig's has seen a big change as the blackberry dies back.
The creek keeps changing as we walk down it - the next section through to Lachlan and Suze's has a bedrock bottom, high sides, Prickly Moses Acacia verticillata doing well, but also many sweet pittostrum.
From there we jumped to Helen's place, well out into the lower slopes, where there's a grand canyon formed only in the last 80 years. Water running fast off the cleared country has eroded the creek, but Dean reckons its stablised now.
Just a little further on, at the Godfrey's place, the creek is back to small banks. Robin Godfrey sent in this photo of this section in the 2010 floods.
Here are grabs from Dean Platt's notes:
Lachie and I
found some interesting plants along the way – Gahnia radula Thatch Saw
Sedge along the Nicolaides-Best frontage and what may have been Dianella
tasmanica nearby to this as well.
Although there
was little water in the creek, some ponds supported aquatics – I would like to
get back and have another look and Russell will be able to clarify with me, but
maybe there was Callitriche near the start of Best u.stream end. I need to
correct that the attractive water lily at Russell and Gill’s is actually the
Cape Pond Lily Aponogeton distachyos (South African) and is a problem in
parts of waterways around the Melbourne area. So it is one to watch out for
lest it becomes completely dominant. I think the ephemeralness of the Sandy may
hold it back a bit.

It was good to
see the Blackberry clearance along the way, long sections have now been
cleared. Excellent and quite probably contributing to the wombat spread into
the creek now. Logic would say that if the wombats have moved into the creek
from the forests of the range above then either the habitat is now improved
along the Sandy or the habitat has been degraded in the range forests. I don’t
think the latter is true so it is likely that the Sandy has improved and
Blackberry removal has been a major change there. Well done. Remember there
is a local native raspberry growing well in sections as well, hopefully it can
spread now.
We didn't make it all the way to the junction of Sandy Creek with Riddells Creek. Dean says it has "rugged volcanic steps with remnant manna gums above blackberry." Here's a photo, and this will be an adventure for another time.
