> on illegal farms on private property
There's been a lot of media hand-wringing recently about ecological damage caused by illegal cannabis grows. I'm not exactly sure why, as it's not relevant to any policy debates.
Marijuana can and should be grown organically and sustainably, there's nothing about the plant which complicates that beyond perhaps the need to prevent pollination.
It's time for robotic scarecrows!
Eventually, all farms will do away with pesticides and either keep out pests or kill them without chemicals. Swat them or catch them, just like the robotic exterminators that will live in the walls and floors of buildings. Maybe they'll even digest them for energy.
Study: Exposure to rodenticides in Northern Spotted and Barred Owls on remote forest lands in northwestern California: evidence of food web contamination

Abstract: The documentation of anticoagulant rodenticides (AR) in nontarget species has centered around wildlife that inhabit urban or agricultural settings. However, recent studies in California have shown that AR use in remote forest settings has escalated and has exposed and killed forest carnivores. Anticoagulant rodenticides have been documented as physiological stressors for avian species. Northern Spotted Owl (Strix occidentalis caurina) critical and occupied habitat overlaps the areas where these studies occurred, yet no data were previously available to demonstrate whether this species was similarly affected. We investigated whether avian predators are also exposed to these specific pesticides and whether Barred Owls (Strix varia) may be a surrogate to indicate exposure rates in Northern Spotted Owls. We documented that 70% of Northern Spotted Owls and 40% of Barred Owls were exposed to one or more anticoagulant rodenticides. None of the rodent prey species sampled within the study area were positive for ARs. There were no spatial clusters for either low or high rates of exposure, though we detected low temporal trend early on throughout the study area. We hypothesize a recent change in land-use toward marijuana cultivation may have led to the increased use of AR in this area. This study demonstrates environmental contamination within occupied Northern Spotted Owl habitat and that Barred Owls can be used as adequate surrogates for detecting these pollutants in a rare species such as the Northern Spotted Owl. Furthermore, additional studies should focus on whether these pesticides are also affecting prey availability for these forest avian species.
"The study, published Thursday in the journal Avian Conservation and Ecology..." I tried to find the publication but their site only shows December and says that next issue is still in production. On another note, we use plastic tubing to keep rodents from chewing or "girdling" young trees and shrubs up here in Canada, it's the deer that really cause trouble.
As opposed to rat poison anywhere else? I don't see this as a failure of pot farming, but rather farming in general.
Good job it's legal then, that means it can be regulated.
Although some products are being phased out, they are still available despite widespread pressure from federal regulators, wildlife officials and environmentalists to remove them from store shelves.
So isn't this more of a regulatory issue than an issue with pot farms in particular? Don't farmers of other crops do the same, or is marijuana particularly susceptible to rats?
What I seem to be missing in this article is an explanation why marijuana farms apparently use so much rat poison in the first place.
This type of story had been reported many times over the years. The only difference is the animal in the food chain in question. Something up the food chain is feeding on something humans want to eradicate. Horrible, yes, but unless they ban such things this will continue. The last time I heard of version of this was Falcon being killed by eating poisoned pigeons in urban areas.
My dog loves hunting rats. Why don't they just get some dogs?
I don't get this story... Illegal grows have been going on for decades in these areas. If anything, there should be fewer now because of legalization right?
seeing an owl in the wild must be worth about 1000 bong hits, gettin high ain't worth this unforeseen consequence... regulated? please...
I remember the war on pidgeons in my hometown by some farmers. They would mix some grain or corn with a fever reducer for pigs or cows. Pidgeons would eat that and fall from the sky, when there metabolism was reduced to a human- aka unsubstainable rate.
Worst of the worst parts was that the resulting "falling birds" spread this stupid panic about the avian flue.
Weed should be totally organic man.
