Hi Allan,
I realize that your
experience and goals are for very different ecosystems than what I'm faced with, but as always there are similarities. The south east coast of Vancouver Island has a "Mediterranean" climate of long cool springs followed by drought lasting 3 to 5 mnths. With climate change, things are getting more irratic. We are trying to improve the soil in an approximate 3 acre field with 3 zones. The field is more or less surrounded by tall cedar forest (some Doug fir and deciduous in the mix - Mother Nature grows really tall
trees on the west coast, so sun is limited in areas in morning and evening). There are 5 large maple trees that were left when the
land was cleared, dotting the field and showing their age with signs of rot. There are sections of the field where Himalayan Blackberries have taken over, and nothing so far has enabled me to beat them back, although I'm beginning to consider trying "chop and drop" just as a soil building strategy.
1. There is an upper zone of very thin soil, lots of rocks, and lots of weed growth. We are running portable
chicken shelters there in the winter when the lower zones flood. The
chickens have made the land *very* uneven digging their dust baths. This year I observed many more dandelions, which I actually consider a good sign.
2. There is a middle zone which is sloped - slightly better plant growth with more grass, but still many rocks. I've tried planting grass, but it's difficult to get the timing right (there's the "planning" part that I'm just not getting right!) and feel it's been unsuccessful.
3. The lower fairly flat ground is the largest section with a winter creek running through. It gets very soggy in the winter, with standing
water if the rains are heavy. This area has had both meat
chickens and layers in portable shelters on it very heavily for the last 5 years. The grass is thick due to the high nitrogen chicken shit. The problem is that we end up having to cut the grass in the spring or it grows too fast to move the shelters through, but if the grass is cut at the wrong time related to the weather, the grass goes dormant - normal for this climate - and we have nowhere for the shelters to go unless we irrigate.
Two years ago, our neighbour inherited a small group of sheep (7 at the moment). As he had only trees we have tried letting the sheep graze the field from the late spring until the fall rains. Last year I tried to divide the field for the spring, keeping the sheep from the start of the slope up to the top. This seemed very hard on the poor soil in the upper area, so this spring I had the owner put a second cross
fence at the top of the slope. We started the animals in the middle zone. They ate it down fairly well. The weird weather we had, possibly coupled with the animal fertilization from last year has resulted in lush-looking weeds in the upper zone. In an effort to not have to mow any more than necessary to keep the two shelters up there still moving, we recently shifted the sheep to that area.
I have been trying to read about various "soil building" and "permaculture" approaches to land management, but I don't feel confident that I'm transfering the key needs to our small eco-system. Everything seems to take too much time and money, with too little results. We either seem to have too much grass, or not
enough and are using far too much fossil fuels (and derivatives in the form of chicken
feed grown elsewhere) for me to consider what we are doing
sustainable. The other half doesn't read about
permaculture (except a variation of what
Joel Salatin does - without the large animals his land has benefited from) thus I need data and expert oppinions to help get him on board. I would like to consider adding some tree guild "islands" but am not sure what plants to use or whether this would really be an appropriate approach for this eco-system. [I was thinking a group with Castanea mollissima (Chinese chestnut), Elaeagnus spp, and Ribes uva-crispa (Gooseberry). Recently I bought a couple of Lonicera caerulea varieties (Honeyberry) to try in the civilized part of the property and since there is wild honeysuckle growing on some of the
fence lines, I could try rooting cuttings of that to add to the group. ]I've tried to read about "forage trees" but worry about introducing something else if it might become invasive. There is "bonsai" Scotch broom as well as the Himalayan blackberry already there.
So some of my key questions:
1. Can the techniques the Savory Institute teaches apply to such a small patch with limited numbers of animals/species?
2. Does the Savory institute have anyone following your teachings in this eco-system? (the map on your website doesn't show any north of California on the coast, or in other areas I believe are identified as "Mediteranean Climate", but I am no expert in the area of geography!)
3. Can you think of ways I can "stockpile" grass or other forage crops - things that can be grown easily when the weather is good that will hold until the sun is too low in the sky for anything to actively grow? Most grasses in this area are types that go dormant in the summer dry spell and are green in the fall and winter, but I'm finding that the fall rains frequently come so late that although the grass turns green, there is not really enough hours of sunlight for it to actually grow much. The lower field zone is too wet to move the shelters through, but the upper zone is so fragile and has so little green that I'm having trouble judging if the chickens might be doing more harm than good even being moved on a daily basis, as frequently it seems that the shelter has to go back over a grazed area before the plants put on any new growth in the low light.
4. Similarly, can you think of shrubs or trees that can provide food for chickens in the heat of the summer when the grass has gone dormant?
5. Can you think of livestock that might be more appropriate than what I currently have available to me? In what sort of stocking rates?
6. We recently "adopted" two male muscovie ducks who do actively eat grass and don't dig the holes the chickens make. Do you think that muscovies might adapt to a portable shelter system and be an environmentally sound addition to the field? Out portable shelters are 10 by 12 ft bottomless hoop houses on wheels. At the moment we have a fleet of 6 of these opperational and a couple down for repairs. We have eagles, ravens, barred owls, hawks, raccoons and mink who all think chicken tastes delicious, so free range is not a safe option.
Sorry, this post is so long, and I'd love to have feed back from anyone with ideas. I am trying to leave at least this patch of planet Earth in better shape than I got it in!
