"Rob & Shel"

There's a dam with a steep clay bank that's eroded by rainfall.
There are
some tiny native sapling trees struggling along.
I want to help these saplings along, stop the erosion (as it silts
into the
dam), & try beautify the bank with further plantings.

If the sapplings are on the wall of the dam, then remove them (I
suspect theya rent' but don't ever grow tress on the dam wall)

If the treesa re behind the dam in the dirrection that the water flows
in from then leave 'em and add anything liek old tyres etc that will
catcht he silt flowing in and revegetate with grasses reeds or
anything that you can get to grow.

Any ideas what I could do?

So far, I've put down some old wool carpet underlay & pinned it in
place
with
thin el-cheapo tent pegs.
Further ideas:
To obtain more of this sort of natural fibre covering & cover the
rest of
the bank where needed. Of course, having holes in the covering for
the
saplings to grow.
Place mangled long sticks, & stake those in place rather like
avalanche
prone areas.
Any long grass slashing; the clippings placed on the sticks.
Chuck any muddy dredging (mainly from the "estuary" part as it's
boggy with
leaves & sticks) on the stick grass mix.
Cross my fingers, & hope it works!

All sounds OK and should work. Look and no doubt you'll learn what
works as you go along.
