Hawaii Game Management Advisory Commission Meeting Minutes – August 22, 2017 TL: So if animal is low in magnesium. What would that mean? KS: What does it mean? I don’t know. Willie-Joe what does it mean if they’re low on magnesium. WC: Most of your mineral analysis from what I understand - it’ll attribute to like low pregnancies – low reproduction. KS: I know selenium is a real important one for that. WC: Yeah. A lot of this stuff goes with repro and not having a good lamb crop this year or whatever. TL: Is that something that salt licks and those kind of supplements? WC: So potentially supplements could be put out. KS: So the animals that we trapped in Puuwaawaa we used salt licks and mineral blocks as our bait to bring them in. And those animals were still on the low end but more normal than the ones that were in Puuanahulu and so next time we trap they’re probably not gonna use any baits and we’ll see if their blood levels have changed because of that. DY: Are these animals healthy or they need vitamins or minerals? KS: It wouldn’t hurt to add – to supplement their minerals, yeah, which is in the plan that we wrote. KS: The GPS collars that we put on are taking four points a day. So we had 24 collars that were GPS collars out there – that map right there – are all of the individuals that we had collared and all of their points for the year. We used those points to estimate home range sizes – we used three different methods for estimating home range – and basically the home range was between 12.7 and 13.35 kilometers. The average distance that they moved within a day was about 7 kilometers – that’s just an indication of how much stress they’re getting from needing to move around from whatever it is – whether it’s from hunting pressure or just to forage or whatever. The home range sizes and I didn’t write it down here – but the home range sizes in Puuanahulu compared to Puuwaawaa were a little bit bigger but their average daily movements stayed the same which is just interesting. Survival – so we had three animals that died and all three were from predation from wild dogs. With the collars the individuals were estimate that there’s about a 90% annual survival rate for adults, which is pretty good for adults. We are doing predator control right now and have been for about the last year and a half. I don’t have any numbers to quantify it but there has been a visual increase in lamb production and recruitment into the population which we’re very excited about and the 15
