We've dedicated significant areas of Nurenga to re-vegetation. Our native plantings have provided wind shelter, they've provided shade, they ultimately reduce the heat, rebounding in the middle of summer, they have introduced a balance to the ecosystem which helps benefit the balance and health that we see in the vineyard. When we are talking about replanting, we're actually trying to put something back into our landscape. The hills are full of great plants. We've just selected a number here that we know grow well based on what we're found in our own native vegetation. People look at the cost of doing anything they're always thinking about what am I going to get at the end of it? We can see long term the benefits but it's costing now to get it started and it's just like the vineyard. You start from scratch the vineyard is going to cost you X number dollars and maybe three, four, five years depending on how this here goes before you get your first crop. It's the same thing with the biodiversity enhancement that we're trying to do. You've got to do the groundwork, you've got to get your plants in, it's just like building a vineyard. What we're not doing is harvesting something to take back to the whirmy to put in to a bottle. What we're doing here is enhancing and harvesting biodiversity and its ability to assist us to grow better grapes. We're trying to blend our bush into our blocks. The way we are doing that is using plantings at the endposts. Everybody's got a leaky drip of line at the endpost and that's just enough water for our perseria and we plant them maybe one every seventh row because that's about the distance. Those beneficial insects travel out into the vineyard and go back to sort of thing. We took a decision from the very beginning that we needed to remove some trees to facilitate the layout of the vines. However, in return for that we decided to devote about 15% of the land area to native vegetation and therefore whether or remnants of vegetation we improve them and enlarge them and whether we're none we planted them from a green field start. We chose a selection of native vegetation, lower, upper and higher story. Some of those things worked very well. However, we found that some of the wottles really had a very short life cycle and so within 10 years they were breaking down and we were having to clean them out. So selection was important. We'd probably do it another way if we were doing this again. But however, we're happy with the native vegetation areas that we now have established. One of the biggest challenges in the Adelaide Hills where you have more than 200 species of native plants is being able to distinguish the native plants from the weedy plants. Some of them are very very similar. So providing landholders with that tiny bit of education around plant identification can go a really long way to a good biodiversity conservation in the hills. Our job is to grow grape vines and grow really good fruit. It's never really been to manage what's around the outsides of the vineyard. We have a number of areas that require work for native re-vegetation. So rather than jump in and do them all at once, which is a big task, we decided to break it down into smaller areas. We've used in our own board to just help us identify native species. We really weren't aware of what was native, what wasn't native apart from the obvious noxious weeds. So it was quite pleasing on some of our areas to see a lot of remnant native vegetation. By just removing the major noxious weeds, we're sort of expecting the native vegetation to just grow and spread. Hopefully we'll get some beneficial insects arrive and live on those areas which can support the vineyard as well. At our Bajana vineyard we have a large waterway feeding into a big dam. There had been cattle on the property at one stage so we've taken them off just to remove the effluent from cattle going into the dam. The area that feeds into the dam had been moored in the past which allowed a really fast water flow into the dam. So we've left vegetation in that waterway now. What that does is slows the water flow down, almost works like a filter to help clean the water for it gets into the dam. That's just one small thing we've done there and that was pretty easy. It was pretty much doing nothing apart from removing cattle and not mowing. At Narenga we've been replanting cleared bare farming land with local endemic species. We've been really fortunate to have the support of trees for life and also have had access to a large bank of volunteers which has the benefit of involving and inspiring our local community to our landscape restoration project. The landscape it doesn't sit with in fences it's a bit like terroir. It sits in its own soil tie, its own rainfall and for those growers to then use that plant association to extend across their re-vegetation sites. Suddenly you're getting into hundreds of hectares of re-vegetation which is really useful for the bird populations that are dropping. It's a really important strategy is to go cross boundaries and join up with your neighbours.
