Today,
Little Stringybark Creek is sick.
It is
scouring and eroding at an alarming rate; it is
polluted, and it supports the sorts of aquatic
animals and plants that indicate that it is a tough
place to live: a much reduced collection of hardy
animals and plants that can survive in polluted
urban streams.
It has
become a problem to those who live along it, whose
land it is eroding, and to its downstream waters to
where it is delivering tonnes of sediment and
nutrients and other pollutants downstream every
year.
Now,
most stream restoration projects set about replacing
habitat, like snags and rock-riffles in the stream,
or replanting stream bank vegetation: undoubtedly
important activities to achieve a healthy stream.
But,
while Little Stringybark has lost in-stream habitat,
and bank-side forest in places, these are not the
biggest problems the creek faces. It is in
much worse condition than similar rural streams with
similar habitat problems.
To
restore Little Stringybark Creek, we aim to start by
addressing the root cause of its biggest problem:
urban stormwater
that runs off the houses and roads of Mt Evelyn in
its headwaters. |
