In 2014, the State of California banned the rat poison that had been increasingly causing sickness and death in wild animals, second generation anti-coagulant rodenticides (SGARs), sold in retail stores as D-con. Although the California Department of Fish and Wildlife had submitted an opinion that the rodenticide needed to be more tightly regulated, it still took 3 years to get the toxin off the shelves of neighborhood stores. However, the ban was not total. Commercial applicators and farmers can still buy and use this poison – and they do.
Killing rats with a slow acting poison, as it turns out, is a very effective way to spread poison through an ecosystem. Rats sick and dying from ingesting rodenticide are caught by wild predators – raccoons, bobcats, mountain lions, eagles, hawks, weasels, – anyone who eats rodents.
Now a newly published study shows that 70% of Northern Spotted Owls (Strix occidentalis) on the North Coast, in the heart of the coastal range forests, where cannabis cultivation has punched holes and created edges, tested positive for rodenticide exposure. Unfortunately, this means that our region is now close to par with the rest of California. An ongoing study in the San Francisco Bay Area undertaken by Wildcare in Marin County has found 83% (updated) of all wildlife tested to be exposed to SGARs. No doubt similar numbers are found in other states and nations.
The world is poisoned. It has been for a long time. From the the first coal mines of Appalachia through the daily spew of burned gasoline and pesticides and even radiation from Fukushima’s ongoing catastrophe, civilization has brought its poisons everywhere it expands. If our civilization lasts to colonize Mars it will bring its poisons there too. From plastics in the oceans to radioactive isotopes in milk, this news is old.

The solutions to humane and effective rodent control are many and require some thought and effort. Thought and effort are exactly what use of poisons seeks to avoid. The impacts to our world from such short-cut seeking are obvious and staggering. Still, the solutions aren’t that difficult. First, conflicts with wild animals, even non-native wild animals like Norway rats, are almost always created by a human housekeeping issue. Feeding pets outdoors, unprotected food storage, unprotected compost bins that aren’t rat-proofed, materials and debris piles around outbuildings, and more all contribute to rodent problems. Good housekeeping solves a lot of the problem. Putting up an owl box can also be useful. Encouraging raptors in your area will also help. Barn owls, Great-horned owls, Red-tailed hawks and others eat rodents for a living! If you have a problem with rats, there are myriad humane and ecologically sound resources available. (see below for resources that can help)
It’s an old formula and in many ways it’s still true: the solution to pollution is dilution. Other measures might be useful to get rodenticides out of our ecosystem, out of of the wild, out of our wild neighbors. Hopefully the legalization of cannabis in California will bring cannabis agriculture into the regulatory process. Maybe legalization will lead to the migration of cannabis agriculture out of remote wildlands and away from sensitive species such as the Pacific Fisher (Martes pennanti)and the Northern Spotted Owl, an icon of the struggle to preserve the Redwoods and the temperate rainforest to our north. But even if that happens, those measures do nothing to dilute the pollutant – to reduce the number of animals exposed to this poison.
Submission to regulatory review isn’t enough. The rat poison put out by a worker at a vineyard in Napa or Sonoma counties is likely legal. When vast swaths of our world are taken over by industrial agriculture, we cannot simply allow that land, its waters, its life, to become a sacrifice zone. If we are serious about diluting rat poison out of our environment, we need to stop producing it. We need to cease manufacture and sales of these poisons.
Update: In 2017, a leader in the effort to rid our shared world of these poisons, Raptors Are the Solution (RATS), worked with California Assembly member Richard Bloom, whose district (50) includes Santa Monica, Malibu, Topanga, West Los Angeles and Pacific Palisades, to bring a bill (AS-1687) forward that would complete the ban of SGARs in our state. It is currently stalled in the Assembly committee, Environmental Safety and Toxic Materials (ETSM). The bill as it is currently written would ban all use of SGARs except
(1) This section does not apply to the use of pesticides for agricultural activities, as defined in Section 564. … “agricultural activities” include activities conducted in any of the following locations:
(A) Warehouses used to store foods for human or animal consumption.(B) Agricultural food production sites, including, but not limited to, slaughterhouses and canneries.(C) Factories, breweries, wineries, or any other location where rodent or pest populations need to be controlled for food safety or agricultural purposes.
At the time of writing it is unknown if the bill will make it out of committee in time for this legislative year. If it does, we’ll keep you posted on actions that you can take to support its passage. For now, we are working to build strong support here on the North Coast, where we treasure our wildlands and wild neighbors, to eliminate these toxins from our shared world, our wild mother.
Want to help? One, contact your representative in the Assembly and let them know that you stand with our wild neighbors and want second generation anti-coagulant poisons fully banned. Here in the second district, you can send a message to our Assemblymember, Jim Wood. Two, help us build support here, in the heart of the Redwoods, where the Spotted Owls for too long has served as a bellwether of the costs our forests and forest communities pay for harmful human practices. You can become intimately involved with protecting our wild neighbors by volunteering at HWCC.

You can help us care for wild animals impacted by the toxins of a human built world, as well as advocate on behalf of our wild neighbors. Please donate today! Thank you!

On a specially prepared perch that reduces captivity related problems such as pressure sores that can develop on the bottoms of a bird’s feet when spending much more time than usual standing and not flying. Perching and other housing choices are an important part of providing effective care. Knowing the natural history of many different wild species is critical if we are to treat patients appropriate to their needs.
In our large aviary (the Merry Maloney Raptor Housing) after getting her splint removed, the Barn Owl exhibits very good flight!
Captured for a routine exam, we are careful not to let these feet, both the tools of her trade and her only real defense against the likes of us, grab us. Tough enough to kill a large rodent, she’d cause some serious damage to a caregiver’s hand if we didn’t treat her talons with respect.
Silently swooping across the crepuscular sky, a Barn Owl is a swift and effective hunter. Even in an aviary, this owl’s flight was awe-inspiring.
That moment when the patient realizes she is free and acts on it is a moment like no other.
Across the field…
And up toward the trees…

Putting as much distance between us as she can before stopping…
She alights on branches at the top of these tall alders and looks back toward us, toward her captors… does she know we helped? Who knows? It doesn’t matter. What matters is that she is free, using a second chance that was given her and this is the last of her looking back…
And then she leapt back into flight and was gone… returned to her wild freedom in the real world.
Evaluation for release includes behavior such as wild food recognition and fear of people, physically, each raccoon must be in good health and fully functional, and a weight check – raccoons must be a certain size before they can considered for release.


In our raccoon housing, we have an artificial river which we use to help them learn that fish and other aquatic creatures are delicious and found in water. When taken to a real river, they know what to do!
Exploring the new world takes time… both raccoons exhibited a very cautious approach after they came out of their carriers. Studies have shown that wild animals who approach novel situations with caution and even fear, do better at avoiding the dangers of the human-built world. Protecting the wildness of our patients is as important as treating their injuries. 
Our last glimpse of these raccoons before they left for the surrounding Wild… and excellent way to close out the year!

A nice way to end a challenging year! A gull’s second chance in a dangerous world!
Our examination found no problems at all. A healthy male Western pond turtle!
We selected a release site along the Eel River near Scotia, where the turtle was first kidnapped.







And then he sunk from view back into the surrounding and surrounded Wild.

Capturing in our aviary for an examination. Handling is very stressful for wild patients. We do so as little as possible.

She left the box with no hesitation and put some safe distance between us before turning ducking into the thicket.
From a safe perch she paused and seemed to consider her options. And for the first time since she was injured she had some meaningful ones!
And then she split.
