Killing Rats with GPS
techmaven writes "When Channel Islands National Park officials needed an estimated about 300 rats exterminated on the east side of environmentally sensitive Anacapa Island, Aspen Ag Helicopters got the call. The kill was necessary because the rodents,
descendants of rats that reached the island by way of a shipwreck a century or more ago, were decimating the populations of two rare seabirds. And GPS helped the helicopter company do the job."

They can have their fun now... But what will they do when the big ones come?

I want GPS on my TV remote control, so I can find it.
Those terrible park officials! They're having those poor rats put to death when all of Ghod's creatures are sacred! What they should do is organize a nice conference where the rats and the seabirds can sit down and air their grievances peacefully, in a spirit of mutual harmony and understanding.
Seriously, this is pretty cool. Any time technology increases mankind's killing power, I've got to cheer a little bit. After the rats, how about some pigeons (also known as the "gutter bird" and the "winged rat," according to Kent Brockman)?

An interesting article, however some of it is a some of this is a little hard to swallow...

their statenments about delivering sprays and pellets by air with an accuracy of 'within a foot' would be quite a thing to see, especially when you watch what a helicopters downwash does to items dropped from below it, and allowing for the pilots abilities (remember, the computer is not flying the aircraft here) - I think there cuold be a bit of wishfull thinking involved here, but I'm sure it looks good on the enviromental reports.
I assume they are using DGPS, which is generally available, for example look at:

also for a basic discussion:

but this will certainly not guarantee you the accuracies they are claiming, at least not unless they are dropping the loads on the fixed beacons DGPS relies on (most provided by the coast guard in the US, also at some airfields).
DGPS is a wonderful development on GPS, but is still not that good. Interesting the russian GLONAS system is a little better (if more expensive for receivers) than GPS.
If they miss just a male and a female rat, the new rats will breed and the offspring will be immune to GPS :=)

...that they sprayed enough pesticide on a small island to kill all 100-300 rats. Either they killed them all, as well as every other living organism on the island that is roughly the same size as a rat, or they didn't kill every rat. Rats are decently sized, it's a lot different than killing insect pests. Insect pests might require a few ppm (parts-per-million) pesticide in the air, but the kill a rat, hamster, gerbil, mouse, bird, anything of that size, would require much much more "pesticide." They must have required quite a lethal dose to get all 100-300 of them, as the article says. Not to mention the fact that the dose would have to be increased to take into account that a lot of the particles will attach themselves to plants, trees, etc... which are above ground. This will not contribute to airborn particles, and will not be able to kill a rat (unless they are of the mutated tree-climbing variety!) So the bottom line is, the dosage must have been huge for this small island. Or else there are still some rats around which have survived. They have probably started mating already. I think bringing in some owls might have been a smarter idea.
A Trimflight 3 system. I work next to the people who designed this system here in New Zealand. And they might have even been using the GPS receiver that I write firmware for, the Ag214 (Also known as the MS750). But they were probably using the Ag132 which only does DGPS instead of RTK.
I'm sure this URL will be circulating around the Ag division of Trimble tomorrow :-)

... so they didn't have to soak the place with RAID. I'm guessing that it is possible to make bait which is attractive to rats, but not birds.
Santa Anacapa is three really small islands, so I doubt there are any native land mammals there (or ones which aren't common on nearby islands.) Santa Cruz island has some native foxes, but that's about it. The seals are quite happy in the area, though. Maybe the beaches are the areas where the poison isn't allowed.
They could have just wrecked a second ship that happened to contain several hundred cats.

...the whole idea of survival of the fittest is dead. I don't see where they get off killing all of those rodents in order to protect a couple of rare birds. If the birds cant survive thats their problem. Damn meddling humans, and that dog. Oh well, just my 2 cents.
I don't know about all this. Increasing yields, paying huge sums of money... in the end, it still means that less and less human intervention is needed, less jobs are created, big farms get richer and smaller farms just can't keep up.
It's not really like technology is helping democratise here, is it?

Your ideas are intriguing to me and I wish to subscribe to your newsletter.
Tell me, when you hope that your CornWholed nutsacks expand in practical use, is that merely a description of the total number of nutsack users, or is that also a description of the carrying capacity of the sack?

Rats living in the wild 'elect' a food taster, who tastes any new food, while the rest of the pack watches. If he/she becmes ill, the rest of the rats don't touch the food.
Even when living in captivity alone, rats will taste a tiny bit of new food, and see if they become ill, finishing the food if not, so the posion they used would have to be increadibly strong to kill a single rat with a single bite, or very slow acting to kill a pack after the taster has sampled it and given it the OK.
Clever little critters. I've kept domesticated ones for many years, and they never cease to amaze me with things they do or learn. You can house train them, get them to come when called, and do simple tricks for treats, just like dogs.
It is reckoned that living in a big city, you are never more than 3 yards away from a wild rat. Nuff said!
When I were your age, all round here were fields...
I can't even afford a call phone, why should rodents be allowed to live with GPS!?
I agree with this post: Kill all the rats with GPS, and give us needy humans some of that technology!

This reminds me of the situation on the Galapagos islands.
Goats had been introduced back when the first sailors had arrived. Now they are upsetting the balance of the ecosystem and must be erradicated. Unfortunatly, due to the delicate nature of the ecosystem, and the general lack of navigability around the island, goat removal options are few.
One is to use $20,000 dollar goat attack dogs (I swear on my karma I'm not making this up) with self-destruct collars (if they attack anything besides goats)
The other is called the judas goat program. One goat is captured, his horns painted and a tracking device attached, then let lose. In a few days he will find another goat herd, at which time a helicopter with hunters (goat snipers, again I'm not making this up) flys over the herd, and methodicaly pick off each goat except the judas goat.
C'mon, how many people, upon reading that headline, immediately thought of the "Killswitch" episode of X-files?
You left off the rest of the story.... they paid the Iscariot goat 30 bucks for his troubles, and he tried to turn it down. But they said take it, and he did. Then guilt came to him, and his goat heart was heavy, and he went off and hanged himself. (and became goat jerky)
It may be cold, but at least it's clear.
