Planting native trees to encourage beneficial insects on your farm

Mike: I’m Mike Arnold and I’m the General Manager of LeaderBrand in the South Island, and, we’re on a 400-hectare farm in mid Canterbury.

[Overheard shots of the farm showing the offices and then fields with tractors on them.]

Mike: It’s predominantly cropping focused on fresh market produce for the supermarkets mainly, and it’s broccoli, asparagus, courgettes, and then we have a whole lot of rotational crops.

Mike: I was approach by Plant and Food to be involved in a project called Hedging Your Bets. And we studied these, um, conifer hedges and pine hedges they had a predominantly around Canterbury and the study was to see what sorts of bugs were in those trees. And I think out of it there’s something like maybe three insects and there’s no real good bugs and there are no predators, no pollinators and so on.

[Mike plants a tree seedling and adds a plant guard to protect it.]

Mike: So then we decided, all right, let’s make a new project now and plant this little native block and let’s study what’s in there. So there’s about 4 or 5 other farmers involved and some really nice little plots like this one here. There’s 7 pollinators in this block here now that we have native bees, hover flies, all sorts of things. And they’re in fact better than bees for pollinating crops. They work when it’s a cold, cloudy day like today. Uh, they’re happy to be out working and pollinating, whereas a honey bee’s a bit cold today, so prefer to stay in bed.

[Mike walks through the new plantings and inspects the trees.]

Mike: If we can make these little areas like this around the farm and do more of them, that would be our intention because we are big on IPM, which is integrated pest management. And integrated pest management really revolves around starting with all your cultural practices and beneficial insects and everything you can do before the last resort, having to get out an agricultural chemical to control the bugs. And my job and our staff revolves around how can we increase the number of beneficial insects because we know we don’t have to spray.

Mike: One thing that I can’t stress enough is the planning that you need to do. So you’ve gotta plan the thing out, okay, the time of the year, your ground preparation. So get some help. If you don’t know, get an advisor.

[Mike talks to camera.]

Mike: Learn by doing is what I say. So do a little bit maybe to start with and learn before you go and do this whole, we’ve done 4 hectares here now, um, do a small area first. We started with, um, say a quarter of a hectare.

[Mike plants a tree in the field.] 

Mike: The benefits of doing that is you’ll learn and you’ll reduce your losses. So I think in this large planting here, we’re probably at like 98, 95, 98% establishment, which is fantastic. And what’s what you need. We’ve always sort of led innovation. That’s one of our, the main things we do. We’re regenerative farming and sustainable farming and we practice it big time. Um, so this is part of that part of that whole practice.

Mike: I mean, this investment here now is probably $80,000. And whilst we may not have an immediate payback on this, we feel, I particularly feel like we’re leading here with somethings that’s gonna be quite big. Customers come here and they see this and they want to get out and take photos and we talk about it and it’s just another aspect of what we do.

[Mike talks to camera.]

Mike: Our aspirations for the future of this farm would be plant more. Um, if you’re mowing a piece of lawn, why mow? Let’s plant into native trees. Let’s have these little plantings all over this whole farm. I’d love people to come here and go, hey, I want our farm to look like this. Any my neighbours and other people in this district, I’d like this whole district to be like this. And I think it could be. Won’t have, I may not see it, but um, what we’re doing here is we’re leading the way and even when I’m not here, it’s gonna be here. There’s some beautiful totara trees already and I’d like to see them in 30 years’ time. Um, it’s just gonna be amazing. Yeah.
