Bill Mollison, the Father of Permaculture, is credited with that concept. I
confess it's often puzzled me because I was raised with the
consumer-discard-and-buy mindset; problems are discarded and solutions are
bought. But the longer I homestead, the less the consumer model makes sense,
especially considering everything we're now being told about the environment.
Anyway, we have two problems. Here's the problem.

| Perennial native grasses |
These are clump grasses, so-called because they grow in clumps rather than an
even carpet-like ground coverage. They are hardy perennials, tolerant of most
weather conditions, and the goats will eat them. Not their best favorite, but
definitely deemed edible. The problem with clump grasses is that they are
difficult to cut, with either lawnmower or scythe because the clumps make
dense bumpy mounds on the ground.
We pretty much leave the clumps alone in our pastures, but in areas where we
want to grow grain or hay, they are in the way. We don't plow, so they become a growing problem. The clumps in
the photo above were a problem because they were growing between the garden
and
hugelkultur bed, where a path is supposed to be. But the clumps made it too bumpy for the
wheelbarrow.
I've tried transplanting these clumps to the pasture, but the goats zero in on
them (Look! Something new to eat!) and the grasses don't survive. Instead, I
wondered if we could use them to address another problem - soil erosion.
I know I've mentioned that our property is a series of ridges, sloping
downward to the back of the property. These tops of the ridges are where we
see the most soil erosion, and we needed a way to keep it from washing down
the hill. One idea I got from
Sepp Holzer's Permaculture, was to make what he calls humus beds to catch soil, sediment, and natural
debris runoff on his mountain. My adaptation has been to make a barrier of
sorts at the bottom of the ridge, using old branches and boards discarded from
Dan's sawmill. The trees hold them in place, and I fill it in with sticks,
branches, weeds, and various cuttings.

We do see some washed soil build-up in these beds, and
eventually, it will all decompose and we'll plant something here. Even so, I
still see erosion is at the top of the ridge, above the brush. How could we
address that?
|
| The path above the ridge is on the left, my bed of branches and sticks are on the right. |
I first read about using clump grasses as a barrier to rain and soil runoff in
a discussion about swales on Permies. One suggestion was to plant a dense row of vetiver instead of digging a
swale. Vetiver is a dense clumping grass that is used successfully in tropical
and sub-tropical areas instead of dug swales. Rather than invest in vetifer,
why not use the clump grasses we already have?
|
| Filling in the top of the ridge with grass clumps. |
So, we've been digging up clumps from places where they're in the way and moving them to the "ditch" where the top of the ridge meets the bed of branches and sticks. Then we mulch them above and below the row.

A row of clump grasses for erosion control. Functional, and I think it looks good too. |
But will it work? I think it will, if it survives transplanting. We chose
the spring rainy season for this project, so it should get plenty of water, and we're keeping the goats off of them for now. If it can
get established before our summer dry spell hits, it should have a
chance, and a problem will become a solution.
