Hi All
I recently bought a lovely little farm in northern NSW Australia. It has a fully developed orchard over about 2.5 acres, which was formerly a commercial stonefruit orchard but is now planted for commercial production of custard apples. The previous farmer was not an organic farmer, used sprays, monocultural planting etc. Also a lovely guy. I am embarking upon rehabilitating the orchard into a diversified, complex
permaculture system. This will take a long-ish time and much work, I know. One of the big infrastructure features of the property is the complete containment of the orchard under fine black bird/hail net, like a massive net circus tent. This kept the flying foxes (fruit
bats) and hordes of parrots off the stone fruit. Actually it is really quite a feat of engineering. Anyhow, I was sitting in the orchard with a friend the other day and we sat quietly for a few minutes and...nothing happened.
Now, anyone with a rich spray free environment will know, these spaces hum, chirp, flit and buzz with living activity. I love to sit quietly and watch the wrens and finches and lizards darting about, listen to the insect chorus and consider the manic mass of life all around me (generally I refer to my 'workforce'). But sitting in the orchard, with nothing of the sort happening around me, I was struck by the silence and stillness. Not natural. Not right. Of course, years of spraying and artificial fertilizer, and a mono-culture has probably done its part in making a less lively space, but I reckon mostly it has to do with this massive net.
So, my question to permies out there is how might I make the net passable for smaller birds, insects etc?
I do not want to get rid of it, it will serve a terrific purpose in protecting crops from marauding bats and parrots. Please understand we have these species in the millions (bats) and thousands (parrots) and they will take any crop to pieces overnight. I have plenty of bush foods and there are several thousand acres of National Parks at my back... my little 2.5 acres of fruit makes not such a vast input to them; I like to share, but I know what the farmer was protecting against!
Anyhoo... I have considered making a series of cuts in the net at the height of the top wire of
fence outside the net, and inserting a 2 inch collar made from large plumbing pipe or similar, fastening the bit so the net does not unravel, and the little collar of pipe is firmly held. My idea is basically to make little portals through the net large
enough for insects, wrens, finches etc, but not large enough for the big raiders. If I did a large number along the forest edge it would look like a wide perforated line along the net. I thought then to plant millet and other tasty treats along the
fence line to encourage the small birds to the 'portals'. I reckon, if there is a lush food site through the holes, they will figure it out and enter and leave the orchard without a problem. Critters are smart! A similar arrangement along the bottom of the net could provide ingress points for lizards, frogs etc...
Well..those are my thoughts...
Anyone else have a brilliant idea to let the world into the orchard without entirely removing the net?
