Journal of Wildlife Management paper documents potential coyote predation of moose calves
AS SO MANY OF THE COYOTE BIOLOGISTS THAT RESPONDED TO MY QUESTION THIS WEEK ABOUT THE ABILITY OF EASTERN COYOTES(COYWOLVES) TO BE A TRUE TROPHIC PREDATOR OF MOOSE REVEALED.........
"MOOSE CALVES ARE VULNERABLE TO PREDATION(BEARS/COYOTES...............CURIOUS ABOUT COUGARS????) ONLY UP TO THE AGE OF 6 MONTHS"..........................

Hi Rick,
I enjoy reading your blog and noticed your recent posts on possible eastern coyote predation on moose. I have a thesis from New Brunswick, Canada that addresses this issue. Basically, they found lots of scats with moose and inferred that coyotes may have killed some moose (at least calves) in deep snow or during calving time in spring. The coyote-moose predation paper starts on page 57 in the attached pdf. I got this paper off the Canadian library's website awhile ago, so I imagine it is still publicly available.
Another study (Journal of Wildlife Management 74(1):P 3–11) found high amounts of moose in coyote scats, and they mentioned 7 calves potentially were killed by coyotes. Here is the relevant extract:
Only the 7 calf
carcasses could have been killed by coyotes because moose
calves are vulnerable to coyote predation only up to 6
months of age (Wolfe 1974, Creˆte and Desrosiers 1995).
Hope this helps.
Urban Carnivores
Ecology, Conflict, and Conservation
edited by Stanley D. Gehrt, Seth P. D. Riley, and Brian L. Cypher
With over half of the world's human population now living in cities,
human-carnivore interaction in urban areas is a growing area of concern and
research for wildlife managers, conservationists, urban planners, and the
public at large. This volume brings together leading international carnivore
researchers to explore the unique biological and ecological issues
associated with mammalian carnivores in urban landscapes.
Carnivores in urban areas are fascinating from an ecological standpoint.
They elicit great passions -- positive and negative -- among humans and
present difficult challenges for wildlife conservationists and managers. The
first section of the book discusses the field of urban ecology and the many
potential roles of carnivores in urban ecosystems, details the general
behavior and ecology of this group of mammals, and addresses the human side
of potential conflicts between people and carnivores in cities. The second
section provides species accounts of the most common urban carnivores,
including raccoons, coyotes, foxes, skunks, and mountain lions. A separate
chapter examines the very specialized place of domesticated cats and dogs.
The last section compares how various carnivore species fare in cities,
looks at the utility of existing conservation and conflict management
efforts, and suggests directions for further research and future management
initiatives.
This thorough examination of the conflicts and complications surrounding
urban wildlife is the first to focus specifically on carnivores. It includes
an extensive bibliography and is an essential reference for wildlife
biologists, mammalogists, and urban planners.

Hi Rick,
While it may be possible that eastern coyotes occasional take a young moose calf, I don’t believe it is overly common. We tagged radio-moose calves for several years in an area just west of Algonquin with a dense eastern coyote, and eastern coyote * eastern wolf hybrid, population and documented only occasional predation by these animals. In the Cape Breton Highlands, where moose are very abundant and eastern coyotes the only “large” canid predator, predation on calves has long been suspected, but to my knowledge not documented. In Algonquin, where we think most canids are the closet living relative to what was once the eastern wolf, predation on moose occurs (calves and adults) but predation on calves by eastern wolves is no more prevalent than that by black bears. In fact, in the northeast states, my suspicion is that black bears remain a more substantial predator of moose calves than eastern coyotes.

Hello Rick-
I think that eastern coyotes have the potential to kill a young moose calf, as coyotes can kill 120-pound+ adult white-tailed deer (esp. if the deer is compromised in any way). I agree with Ed that such an event would be uncommon given the current low density of moose on the landscape. Heat stress might be a more important factor for future moose populations with earlier and warmer spring temperatures resulting from climate change.

Wolverines in Sweden have adjusted to living in people dominated environments
Tricksters, Depredation, and One Funny Dog (from the WOVERINE BLOG)
The wolverine's reputation as a tricky devil is probably outweighed by that of another, much more common North American carnivore: the coyote, who features in the lore of dozens of Native American tribes as a sly conman, a buffoon, or a serious troublemaker, depending on the occasion.
So it seems fitting that Coyote and Wolverine have teamed up: the Cascades Carnivore Project's sole gulo scat sample, which the project was having analyzed to determine its sex and genetics, turned out to belong not to a wolverine, but to a member of the Canis latrans family. Apparently the coyote was following the wolverine's tracks (I've seen this as well; a coyote walked in the wolverine tracks I found in Death Canyon in February, confusing the heck out of me for a good mile) and left a deposit.
Determining the sex of the Cascades wolverine was a prerequisite of a contest to give a name to the critter, but in light of the continuing mystery, they settled on the androgynous name of Wildy - certainly among the more fitting names for a wolverine, regardless of sex - and are determined to collect another sample sometime soon. I'm eager to find out, so hopefully Wildy will be good enough to enlighten us soon.
In other gulo news, I was talking to a wildlife biologist who recently returned from Sweden, and he mentioned his surprise at the ability of Swedish wolverines to survive in an intensively managed landscape. All of this is anecdotal, and wolverines are not his species of focus, but he mentioned that in Sweden, no tree is more than 500 meters from a road - a design of the government to enable easy forestry activities - and that despite logging and traffic, wolverines negotiate this landscape successfully. Like most of us, he was surprised that an animal so emblematic of wilderness - to the American mind, anyway - was capable of living in such proximity to industry.
Swedish wolverines also run the risk of retaliatory killings by Sami, whose domestic reindeer herds are vulnerable to depredation. In its commitment to maintaining wolverines, the Swedish government came up with a payment-for-ecosystem-services model to help prevent herders from killing wolverines. If a wolverine dens in a herder's territory, the herder is paid $30,000 up front, which seems to work better among the Sami than post-depredation compensation programs for wolf kills have worked among American ranchers (the Sami also receive payment for a wolf den on their land - $70,000 - but even this rate of payment isn't enough to build tolerance for wolves, which scatter reindeer across the landscape - a more grievous difficulty, evidently, than the loss of a few animals to depredation, since it makes herding extremely challenging.) There are apparently some problems with the payment system for wolverine depredations, but the level of payment at least represents a serious commitment to conservation on the part of the Swedes. Fortunately we don't have to deal with the question of livestock depredation by wolverines here in the US, but several of my herder friends in Mongolia mentioned that wolverines do sometimes prey on sheep and goats. One of the objectives of my project in Mongolia this summer is to determine exactly how prevalent depredation is, and how Mongolians respond to wolverine depredations, as opposed to wolf, lynx, or snow leopard depredations.
Govenor Rick Perry of Texas shoots and kills a coyote while jogging with his dog
Texas Gov. Rick Perry shoots coyote that threatened his dog
By: JIM VERTUNO
Associated Press
04/28/10 4:33 PM EDT
AUSTIN, TEXAS — Pistol-packing Texas Gov. Rick Perry has a message for wily coyotes out there: Don't mess with my dog.
Perry told The Associated Press on Tuesday he needed just one shot from the laser-sighted pistol he sometimes carries while jogging to take down a coyote that menaced his puppy during a February run near Austin.
Perry said he will carry his .380 Ruger — loaded with hollow-point bullets — when jogging on trails because he is afraid of snakes. He'd also seen coyotes in the undeveloped area.
When one came out of the brush toward his daughter's Labrador retriever, Perry charged.
"Don't attack my dog or you might get shot ... if you're a coyote," he said Tuesday.
Perry, a Republican running for a third full term against Democrat Bill White, is living in a private house in a hilly area southwest of downtown Austin while the Governor's Mansion is being repaired after a 2008 fire. A concealed handgun permit holder, Perry carries the pistol in a belt.
"I knew there were a lot of predators out there(YOU AND YOUR DOG BEING SOME OF THOSE PREDATORS, DEAR GOVERNOR) You'll hear a pack of coyotes. People are losing small cats and dogs all the time out there in that community," Perry said.
"They're very wily creatures."AND SMART...........AND SURVIVORS)
On this particular morning, Perry said, he was jogging without his security detail shortly after sunrise.
"I'm enjoying the run when something catches my eye and it's this coyote. I know he knows I'm there. He never looks at me, he is laser-locked on that dog," Perry said.
"I holler and the coyote stopped. I holler again. By this time I had taken my weapon out and charged it. It is now staring dead at me. Either me or the dog are in imminent danger(THE DOG, NOT YOU!) I did the appropriate thing and sent it to where coyotes go," he said.(NOTHING TO BE PROUD ABOUT, GOVENOR)
Perry said the laser-pointer helped make a quick, clean kill.
"It was not in a lot of pain," he said. "It pretty much went down at that particular juncture."
Texas state law allows people to shoot coyotes that are threatening livestock or domestic animals. The dog was unharmed, Perry said.
Perry's security detail was not required to file a report about the governor discharging a weapon, said Department of Public Safety spokeswoman Tela Mange.
"People shoot coyotes all the time, snakes all the time," Mange said. "We don't write reports."(PERHAPS YOU SHOULD BE INVESTIGATING THESE KILLINGS, MR. MANGE)
The governor left the coyote where it fell."He became mulch," Perry said.

Rick,
I don’t ever remember seeing coyote predation on moose calves documented in the literature. But I have assumed the larger eastern coyote, hunting in family groups, probably is able to take a moose calf opportunistically. How often this might happen is unknown to me, but I do know that Vermont’s moose herd grew very rapidly during the 1980’s and 90’s, even though Vermont was saturated with coyotes. Thus coyotes were certainly not suppressing the moose population in any significant degree.
New Hampshire has investigated calf mortality and perhaps Moose Biologist Kris Rines has some insight to share. Dr. Pete Pekins at UNH has studied food habits and energy requirements of coyotes and may also have some information on the subject.
Thanks to all,

Hey Ced!
I’m pretty sure they take neo-nates, perhaps at a lesser rate then they’re take of fawns due to more maternal umph by the cow. Tony often saw coyotes and bears near calf resting areas. We never knew what caused them to disappear but we did lose about 30% of them in the first 8 weeks.

DRAFT SIGN-ON LETTER
To: Premier Gordon Campbell
The undersigned organizations are strongly opposed to the killing of large carnivores (wolves, cougars, bears, wolverines) to save the mountain caribou. Wolves and cougars are currently being trapped and shot as part of the Mountain Caribou Recovery Plan. The government has proposed to escalate the elimination of wolves by shooting them from helicopters. We oppose all these practices for the following reasons:
1. Predation did not cause the decline of mountain caribou populations.
Human activities that destroy or intrude into critical habitat are the main causes of the decline of mountain caribou populations. This includes the logging of old-growth forest, roads, mining development and dams, as well as snowmobiling and heli-skiing, Increased predation is a side-effect of these activities, especially where roads create easy access lanes for predators into formerly pristine caribou range.
2. Killing top carnivores will not save the mountain caribou.
Scientists have advised that the continuation of logging and mining, as well as snowmobiling and heli-skiing, in mountain caribou habitat will be fatal to the species. The Recovery Plan is allowing all of these activities to continue extensively.
The plan is to eliminate large carnivores in the vicinity of the smallest, most threatened herds. These herds are small because they have lost habitat on a massive scale. Even if we could kill all the predators, these herds could still be wiped out by incidents such as automobile accidents, avalanches, stress from snowmobiles and fluctuating winter conditions unfavourable to their survival.
3. Top predators play critical roles in maintaining healthy ecosystems.
The negative effects of removing top predators cascade down through the whole food chain. It has been known to cause the failure of forests to produce young trees, the loss of riparian vegetation, causing the serious erosion of streambanks, the extirpation of many species of small animals, and the brutal starvation of herds of deer, elk and other ungulates due to overgrazing. Young forests such as those being created by too much clearcutting in mountain caribou habitat need top predators to protect them from overgrazing by prey species.
4. Predator control practices include the killing of upwards of 80% of wolves over large areas for many years or decades. The undersigned have grave concerns about the long-term survival of wolves due to the cumulative effects of such programs, which are periodically undertaken in BC.
The theory says that wolves always recover quickly after the “program” ends, but similar practices eliminated wolves in the lower United States, requiring the U.S. to import wolves from Canada to correct serious ecological imbalances. Some wolf experts point out that east of the Columbia Mountains in the Rockies proper, and west on the Okanagan Plateau, wolf population recovery has been spotty, incomplete or non-existent, even in the mountain national parks. Many poorly understood environmental conditions may influence the ability of wolf populations to recover. Underlining this concern is a lack of data to refute the possibility that wolf populations are already fragile in the Columbia Mountains Region. The province has not provided data on the population density or any demographics that would indicate that wolves or cougars, can withstand added killing. This short-sightedness belies a total lack of an ecosystem-based management perspective that underpins more enlightened wildlife management.
5. Sporadic predator control programs in BC have been driven by politics, not science. Increasingly they incorporate science to legitimize political objectives.
Claims that predator control is needed for one reason or the other have been used to achieve other objectives such as benefitting hunters or scapegoating predators for the damage done by humans. The truth of what really what goes on in the woods during predator control is often withheld from the public or not even monitored by the government. Seemingly benign activities such as wolf-collaring and wolf-sterilization have at times been used as tools to assist the more thorough elimination of wolves, as when collared wolves are tracked to locate home ranges and dens, and then killed; or the sterilization of mating pairs is accompanied by the slaughter of all the other pack members.
6. Large carnivores are intelligent animals with amazing family relationships. They have an intrinsic value in and of themselves, and a right to life.
7. Lastly, the undersigned declare that the following methods of predator control are cruel and unbefitting to the dignity and principles of the human race.
· Chasing wolves to exhaustion with helicopters and shooting them from the air, which is now being considered in BC;
· Leghold traps and snaring, followed by killing, which is currently happening in BC;
· The use of poison, which occurred in BC in the 1980s and is currently occurring in Alberta.
In view of these factors, we urge the BC government to cease killing large carnivores immediately and undertake scientific studies of the ecology of these animals. We recommend the following steps to protect mountain caribou without doing further ecosystem damage:
1. Stop clearcutting and road building in all mountain caribou habitat; the continuation of these practices only increases habitat for moose and wolves.
2. Stop snowmobiling and heli-skiing in historical mountain caribou wintering areas. The current snowmobile closures are too few and too small, and they are not being enforced.
3. Habitat restoration in clearcut areas is crucial, including the decommissioning of old roads.
4. Reduce the speed limit on the Salmo-Creston Highway, where a number of animals in a critically imperiled herd have been killed by passing vehicles.

Thanks for the e-mail. It definitely is food for thought. We do have the larger Eastern Coyote, Canis latrans, well established here in Westchester County which is just to the north of New York City (yes, they have them there as well). What we don’t really have is a population of Moose, so your direct question about coyote predation on this species is moot. At best we might get an occasional wandering animal which, to my knowledge, has only been two in the past five years, one of which was across the state line in Connecticut, and as I recall, suffering quite a bit from heat exhaustion.
We do “see” coyotes taking white-tail deer fawns, which is a good thing since the deer population down here is “out of control”. They may also take an adult animal, but we think that sickness or starvation might be complicit in turning one into a prey item. There has also been some (anecdotal) evidence of “pack behavior” in taking adult deer (in deep snow), but that is not well substantiated. It has yet to be determined whether the Eastern Coyote is at all effective in managing the white-tailed deer population.
That said, if coyotes are being successful taking adult deer, I do not see it being a difficult permutation for an adult coyote to take an inexperienced Moose calf, but this after all, is nothing but conjecture on my part.
I hope this bit of information has been helpful.

Rick,
Thanks for your note, and I've enjoyed reading your emails and the literature you've sent around over the past year.
Interesting question about coyotes. I have found very little in the literature that mentions coyote predation on moose calves in the northeast or elsewhere; as you probably know, the smaller western coyote does take elk calves, so it seems plausible that the larger eastern coyote could take a moose calf. My sense is that such an event would be uncommon and therefore compensatory rather than additive.
Yes, that is the question about southern New England moose. How are they coping in temperatures that far exceed their documented heat stress thresholds. My guess is that the relative shortage of predators (and lack of hunting) in SNE may be playing a role. Moose can bed down and cool off without threat in this landscape, and therefore may be able to thermoregulate more effectively here than in regions where they have to be more vigilant.
Re: the effects of wolves on moose in the Great Lakes, I would defer to folks like Rolf Peterson and others who are more qualified to answer such questions.
Yes, Quabbin's deer population has been drastically reduced from 11-23/sq. km in the late 1980s to 2-7/sq. km today because of a controlled hunt that began in the early '90s. Hunting was prohibited in the Quabbin for about 50 years prior to that.
Best,
Ed

I would not think that coyotes would be a huge impact on moose. Moose calves are quite a bit larger than even elk calves, and I would suspect that their period of vulnerability would be quite short. That is not to suggest that they could not take moose, especially if they had formed pack hunting techniques which is more effective with larger prey. But my guess is that they have so many more deer that they could attack that they would choose deer over moose. That is the situation in many other regions where both elk and deer exist--the wolves choose deer because they are easier to bring down. I suspect eastern coyotes would make the same choices about prey size and availability

Rick,
I suspect the main limiting factor for moose in southern New England is summer temperatures. Take a look at the new research coming out of Minnesota (i.e., a Wildlife Mono. as well as recent papers in the JWM). Higher summer temperatures increase parasite loads and reduce body conditions. A lowered body conditions, although not directly studied to date in this specific context, would be expected in increase predation mortality (i.e., easier to capture prey).

I don't doubt that they are capable of preying on moose calves, particularly neonates. The question, however, is to what degree and to what impact.... Obviously that will require some study. I think we still have a LOT to learn about the impacts of coyotes on the rest of the wildlife community throughout eastern North America. In addition, it appears to us that the behavior of this animal in the east (or at least the Southeast) is quite different from its western counterparts. Clearly a fertile area for research!

Hi Rick,
I mostly agree with Ed's account. Smaller western coyotes do prey on elk calves and I suspect eastern coyotes/coywolves prey on moose altho it hasn't been documented yet. I bet it does happen though. Certainly coywolves can prey on deer but I don't suspect they will ever have a big effect on moose altho it is debated how much of an effect lycaon would have on moose but I bet it would be more than coywolves...
Yes, I still check out your site a couple times a week! great work,
thanks, Jon
No problem Rick. In summary, I see the eastern coyote/coywolf as being like the western coyote but with more dietery flexibility which is kind of amazing given the legendary propensity of western coyotes to eat anything. Many of the dietery studies have been done in more Northern areas that don't have a diversity of prey. More needs to be done in places like my study area - suburban and varied prey supply.

I also am unfamiliar with specific documentation of coyote predation on moose calves. However, I know a number of coyote diet analyses are currently underway by researchers in the NE. In NY, Jacqui Frair at SUNY ESF is conducting a study of coyote foraging ecology - she may have some more specific information for you re: moose.

Dear Rick,
Thanks for your message. I’m not aware of any reports of coyotes preying on moose calves in NY or New England. I’m also not likely the best person to ask. I would defer to State Wildlife Agency staff.

I don't think I've seen moose ever reported in eastern coyote diet, although I'm not sure there have been that many studies in good moose country.??
I think you have to be pretty big/pack hunting to tease a baby away from a moose momma and I wouldn't bet that eastern coyotes are up to that.
I've rss'ed your blog so keep an eye on it.

Rick - no evidence that coyotes prey on moose calves in Michigan or Minnesota. Whenever moose calves have been radiocollared (and it now numbers in the high hundreds), black bears emerge as the most important predator of moose calves in summer. We did this first on the Kenai Peninsula in Alaska in 1977, and it has been repeated in many places. If there is significant predator-caused mortality, bears would be my first bet.

Why are Moose successfully recolonizing a warming New England when they are losing population in the colder Great Lakes States?
In the most recent peer-reviewed Northeastern Naturalist magazine, Faison and colleagues examine in depth Moose foraging in the Temperate Forests of Southern New England. They reveal how Hemlock and Red Maple are the browse of choice for our most recent Eastern herbivore returnee--(Alces alces L. Moose) and what impact that browing pressure might mean for those species as well for Oak and White pine recruitment into our Eastern woodlands.
Also explored thoroughly and what I concentrate on below with my corresspondence with Ed, Rolf Peterson(wolf and coyote biologist in the Great Lakes region) and Roland Kays(coyote biologist NY State Museum) is why the Moose in Minnessota, Michigan and Wisconsin are in drastic decline when Moose in our Northeastern region are multiplying and returning to historical haunts that they have not occupied since the 19th Century?
Enjoy the read and commentary on the Post above this one by clicking link....................fascinating and revealing!

Rick,
Thanks for your note, and I've enjoyed reading your emails and the literature you've sent around over the past year.
Interesting question about coyotes. I have found very little in the literature that mentions coyote predation on moose calves in the northeast or elsewhere; as you probably know, the smaller western coyote does take elk calves, so it seems plausible that the larger eastern coyote could take a moose calf. My sense is that such an event would be uncommon and therefore compensatory rather than additive.
Yes, that is the question about southern New England moose. How are they coping in temperatures that far exceed their documented heat stress thresholds. My guess is that the relative shortage of predators (and lack of hunting) in SNE may be playing a role. Moose can bed down and cool off without threat in this landscape, and therefore may be able to thermoregulate more effectively here than in regions where they have to be more vigilant.
Re: the effects of wolves on moose in the Great Lakes, I would defer to folks like Rolf Peterson and others who are more qualified to answer such questions.
Yes, Quabbin's deer population has been drastically reduced from 11-23/sq. km in the late 1980s to 2-7/sq. km today because of a controlled hunt that began in the early '90s. Hunting was prohibited in the Quabbin for about 50 years prior to that.
Best,
Ed

Ed and David
As always, enjoy the clean, crisp writing style and information-filled articles coming out of your Harvard Forest team.
Just read your just published Moose impact research in Northeastern Naturalist and had a couple of questions:
-in addition to black bears preying on moose calves in Spring and early Summer, what might u expect the impact of our Northeastern coyote(coywolf) to be from an additive rather than compensatory basis?
- as u state,in the Great Lake States, moose are shedding population due to a synergy of heat stress and winter tics(and worm induced brain disease transmitted by whitetails)..........with southern ne england recording average temps higher than that of Minn, Wisc. and Michigan............with deer desities that I imagine to be similar and with deer ticks in the East at an all time high,,,,,,,,,,,how have moose been able to thrive as far south as ny and Connecticut?
While true that that the Great Lakes supports a spectrum of both Gray(C.lupus) and Eastern Wolves(C lycaon) as well as coyotes and black bears...........are the modest population of wolves a dampening factor and the causal agent of moose decline???
Almost amazing that the more densely populated southern new england and mid atlantic NY can find moose recovering and expanding despite warming conditions(especially evening temps), high densities of whitetails(although sounds like Quabbin and Ware River are at lower levels than a decade ago due to sharpshooter efforts(????) And a now "larger coyote(40-50 pounder) predator synergizing with bears.
Any further thought on the above two stated questions is appreciated.
Many thanks for your time and appreciate you perusing my blogsite.
David........a special hello to u!!

As Posted earlier this week, the Native Fish Society focuses on the preservation and restoration of native fisheries across the Pacific Northwest. Russell Bassett is the River Steward Coordinator for this Group and he and his colleagues are hard at work on such projects as salmon recovery plans, limiting timber harvests on river adjacent floodplains and upland forests, creating Federal protected habitat designations for bull trout and getting Wilderness acreage in the John Day Basin.
Restore the Salmon,,,,,,,,,,,,,,,,,,,,,,,,,,,,bring on the black bear and Griz as trophic top down predators of the fish.................................restore the watersheds of the Northwest to conditions that enable all of us animals to thrive ........................
Russell can be reached at 503 829 6211.........................We urge all of our Coyotes-wolves-cougars.blogspot.com readers in the Northwestern States to get involved in this great effort.
Native Fish Society River Steward Program
Dedicated volunteers, incredible achievements
The concept of river stewards is not new. The earliest stewards, or riverkeepers, served their communities as far back as the Middle Ages. They patrolled village streams and rivers to protect them for the benefit of all inhabitants. The first fulltime U.S. riverkeeper was a former commercial fisherman turned activist who was hired in 1983 by the Hudson River Fisherman’s Association to help identify polluters who were breaking environmental laws on the Hudson. During the past 25 years, riverkeeper programs have emerged in large urban rivers like the Willamette as well as classic fisherman’s rivers like the Russian River of California.
Today, the growing population creates challenges that were inconceivable for the early river stewards. Development, water rights, land use, farming, roads, hydro projects, recreation, commercial and sport fishing, hatcheries, logging, and climate change create greater impacts on our river systems.
Thankfully, there are dedicated individuals who have taken on this daunting task on many Pacific Northwest rivers – the Deschutes, the North Umpqua, the Rogue, the John Day, the Klamath, the Skagit, and the Molalla, to name a few. Native Fish Society River Stewards are mentored through a program that includes scientific and geologic education, retreats, policy issues, and tools to encourage involvement of local citizens. With more than 50 years of dedicated wild fish advocacy and study, the NFS staff provides for the growth and effectiveness of the Stewards.
The NFS River Steward Program began six years ago with the original purpose of compliance monitoring, making sure the Oregon Department of Fish and Wildlife fish management program is consistent with the Native Fish Conservation Policy. The program has grown considerably since its conception, and while NFCP compliance remains a strong focus, NFS River Stewards go beyond compliance to conserve, protect and restore native fish populations in their watersheds through a variety of ways, including identifying threats to recovery and developing solutions, creating coalitions to stop threats to native fish, habitat restoration, nutrient enhancement, fish monitoring, public education and community outreach.
There are currently more than 50,000 square miles of Oregon and Washington watersheds covered by 31 NFS River Stewards.
In its first five years, the River Steward Program has seen many incredible accomplishments for native, wild fish and their habitats in the Pacific Northwest. In 2009, these accomplishments include:
• Stopped threats to the Metolius River from destination resorts.
• Installed hatchery-fish exclusion weirs on the three most important wild steelhead spawning tributaries of the Deschutes River.
• Completed work on the first draft of Oregon’s next conservation plan through participation in the South Coast Fall Chinook Native Fish Conservation Plan Advisory Committee.
• Moved the Molalla River much closer to receiving Wild and Scenic designation, protections we expect to earn in 2010. The U.S. House voted to approve designation in November.
• Created recovery actions for Molalla River spring Chinook salmon and winter steelhead in cooperation with the National Marine Fisheries Service, Oregon Department of Fish and Wildlife and a private fisheries consultant that are being incorporated in the Upper Willamette Recovery Plan, including a reintroduction of wild spring Chinook to the Molalla River.
• Successfully defended catch and release of N. Umpqua wild winter steelhead.
• Conducted watershed restoration and salmonid recovery educational presentations to more than 500 people on Central Oregon Coast watersheds.
• Conducted spawning surveys of Salmonberry River winter steelhead and coho, and Molalla River winter steelhead. Conducted temperature monitoring on the Molalla and Salmonberry rivers.
• Documented devastation caused by land use practices to the Salmonberry River.
The above accomplishments are proof that the Native Fish Society is on the forefront of effectiveness. We have no intention of slowing down, either! Examples of the projects and campaigns NFS River Stewards are working on into 2010 include:
• Helping federal and state agencies develop and implement scientifically-sound recovery plans. Current plans Stewards are working on include the Lower Columbia Spring and Fall Chinook, Steelhead and Coho plans, Mid-Columbia Steelhead, Upper Willamette Spring Chinook and Winter Steelhead, Columbia River Chum Salmon, Coastal Fall and Spring Chinook, and Oregon Coast Winter Steelhead
• Developing a detailed threats assessment of the Upper Deschutes Basin
• Stopping increased timber harvest in Oregon state forests.
•regulations for keeping catch and release on N. Umpqua wild winter steelhead.
• Creating a citizen-based conservation plan for N. Umpqua wild winter steelhead
• Reintroducing wild spring Chinook to the Molalla River and constructing fish habitat on the N. Fork Molalla.
• Developing alternatives to a dam on Bridge Creek of the middle-fork John Day.
• Working within the City of Medford’s Comprehensive Plan to ensure fish-bearing Bear Creek tributaries are treated as such when the city approves development permits.
• Reducing or stopping trout stockings on the McKenzie River.
• Getting federal critical bull trout habitat designation for the Upper Deschutes
• Bringing more lands into public ownership in the Alsea, Yachats, and Molalla river basins.
• Creating more wilderness in the John Day Basin.
• Removing the use of bait on the John Day and McKenzie River.
