Farm Design: The BIG Picture:

Thanks to a drone picture from our interns, I can explain a bit about our farm design from a different perspective. While this image only shows a small part of the farm it does capture an intersection of farm systems.

One of the first major changes we made on the farm was fence off a remnant wetland in 2016 and plant native grasses, flax, shrubs and trees. The aims are to improve water quality, control erosions, provide habitat, and increase biological diversity.

Next we bisected the valley with fencing and designated one side for goats and one side for kune kune pigs. On the goat side – where you can see the bee hives – we’ve planted around 50 poplar poles to stabilise the slopes. Each of these is protected by a heavy duty plastic sleeve to prevent the goats from stripping the bark.

On the pig side we have planted around 40 poplars, 32 olives, and 60 akeake trees, all of which are unprotected because the pigs eat grass but do not browse trees.

Next we fenced the rest of the stream, which goes far beyond the picture shown here. Along this stretch of stream we’ve planted primarily cabbage trees and Australian river oak (casuarina). Both are known to have fibrous root systems that are good at holding stream banks.

Part of this area contains a small hillside formerly covered in gorse and thistles, as well as another remnant wetland. We’ve planted more native trees, flax and willows there. This area can be used as an emergency browse block in case of severe drought.

The area under the pines provides seasonal grazing as needed. We can rotate the goats or  pigs through this area to rest other paddocks.

Most of the farm has poor soil drainage that does not suit avocado trees. But there is a shelf of land above the stream that has better drainage that will host 30 to 40 trees. We’ve fenced this area temporarily to establish tagasaste (tree lucerne) as a companion to the avocados.

The olives are on the dry and windy hillside above the avocados.

We planted 40 ake ake on a dry hillside on one side of the large poplars seen in the middle of the image and another 20 on the other side of them. Ake ake are well adapted to dry conditions.

In the short term we are having to hand water many of these trees, but in the long term they will contribute to the resilience of the farm. Trees help build resilience to both drought and flood. We’ve planted over 2,000 in the last four years.

At present the bees are managed by a contractor who pays us an annual fee. We have a good diversity of flowering plants that provide more-or-less year-round bee fodder.
