Abstract: Recovery programs for federally listed San Clemente loggerhead shrike (SCLS; Lanius ludovicianus mearnsi) and San Clemente sage sparrow (SAGS; Amphispiza belli clementeae) have been conducted by the U.S. Navy since the 1990s. Non-native mammalian predators were implicated in the historic population declines and remain an obstacle to recovery. The population of SCLS reached a low of 14 individuals in 1998, requiring extreme measures to protect the population. We have worked with the Navy to reduce predation threats by developing a variety of innovative technological techniques for managing predation. These include shock-collars attached to native island foxes (Urocyon littoralis) to protect nest sites, and a variety of still-frame and video monitoring systems to identify species predating nests. An automated trap-monitoring system allows us to be immediately alerted, either directly or via the internet, if a trap has been tripped. Finally, we employed a mobile, thermal infrared surveillance and video camera system allowing us to locate, identify, and removal spotlight-wary feral cats. These techniques have provided a more quantitative understanding of predation effects and allow us to better allocate protection efforts. In the future these and similar technologies will likely play an increasing role in SAGS and other avian species recovery programs.

Abstract: San Nicolas Island foxes (Urocyon littoralis dickeyi) suffered a dramatic decline from 2009 to 2010, following island-wide removal of feral cats (Felis catus). Foxes have been monitored annually since 2000 on three trapping grids. Although San Nicolas Island supports higher densities of foxes of any California Channel Island, population declined 30%-50% on two grids and remained relatively stable on another. Adult survival also decreased 37% in the two grids, while increasing in the other. There was also a decrease in juvenile survival from 2009-2010 relative to previous years. We examined several possible mechanisms for the decline. Feral cat removal was ruled out because being captured in a leg-hold trap did not decrease fox survival. We could not rule out virulent disease since there was a marked increase in canine adenovirus and canine distemper exposure. However, we handled 290 foxes in 2010 to assess potential impacts of cat removal on individual foxes, and no foxes showed clinical signs of disease. We rejected a dramatic loss of food resources since fox weights did not differ between 2009 and 2010. We concluded that the most likely cause was negative density dependence in adult survival. The mechanism underlying density dependent survival rates remains unknown.

san nicolas island feral cats: HSUS press release

Feral freeroaming outdoor cats in Maine

Since 2006, the Maine Chapter of The Wildlife Society has worked on the feral or free roaming or outdoor cat issue. In March 2007 they issued a Feral Cats position statement opposing Trap Neuter Return (based on the position statement of the national The Wildlife Society) that is also hosted on the website of the Maine office of the US Fish and Wildlife Service. The Maine Chapter of TWS prepared a mailing to all veterinarians in the state of Maine and formed the Feral and Outdoor Cat Committee. Several years ago they began planning a feral cat study to document locations of feral cat colonies in Maine and their impact on wildlife. In their November 2011 newsletter and on the Maine Wetlands website, they request help with the study, and report having “documented 33 likely locations of feral cat colonies ranging in size from 10 individuals to nearly 100.”

~ ~ ~ ~ ~

Feral Cat Blog! Notes:

In November 2011 I advised leading cat advocates nationwide that the HSUS rep in Maine, Katie Lisnik, began hosting freeroaming cat forums and prepared a report on Freeroaming Cats in Maine. (Katie Lisnik is now the national HSUS Director of Cat Protection and Policy.)

In December 2009 I shared the following with leading cat advocates nationwide:

[begin]
You'll recall the essay, Critical Assessment of TNR, authored by Longcore of The Urban Wildlands Group* that I shared in April 2009. Shortly after, a group of environmental people** who do not favor Trap-Neuter-Return issued a related paper issued by Lepcyzk et al., What Conservation Biologists Can Do Regarding Trap-Neuter-Return: A Response to Longcore et al.
Downloadable doc file
http://cwhrbird.org/documents/Conservation_Biology_Response_to_Longcore_et_al.doc
One of the authors, Elizabeth Stone, DVM, is on the board of the Center for Wildlife Health Research, a Maine group with interest in the feral cat and wildlife problem. You’ll note their Maine cat survey, research they plan, school curriculum regarding cats, and board member bios.
http://cwhrbird.org
Very interestingly, Dr. Stone is opening a high-volume, low-cost spay/neuter clinic for cats in Pownal, Maine “as part of the CWHR‘s strategy to reduce cat depredation on wildlife.” An education component is included. The clinic is listed as pending with Humane Alliance‘s NSNRT program.
The Maine Chapter of The Wildlife Society has issued a position statement against TNR, based on that of the national group. A letter in support of a grant application for Dr. Stone’s spay/neuter clinic has been submitted by the Maine Wildlife Society to the Maine Outdoor Heritage Fund. The Maine Wildlife Society is also working with a student to investigate the impact of feral cat colonies on Maine’s wildlife and species of concern. They sent a letter in May 2009 to Maine veterinarians with their position statement and asking for help in promoting indoor cats .
* Longcore, Travis - The Urban Wildlands Group is one of the six conservation groups that filed a lawsuit in June 2008 against the City of Los Angeles where the judge’s decision December 4, 2009 ruled against City support of TNR. In Jan 2007 I learned of the CEQA requirement for LA Animal Services and contacted Boks, then GM, for the report which was in process.
** Lepcyk and Hatley (I’ve shared their papers on forums and on Feral Cats in the News ~ the Feral Cat Blog!); all are familiar with Temple!)
[end]

A few days later in December 2009 I mentioned:

 
[begin]
Something I meant to include in this message was a disturbing comment in the January 2009 minutes and March 2009 newsletter of the Maine Chapter of The Wildlife Society.

[quote]
In addition to TNR, need to declaw cats so they don’t continue to wreak havoc on wildlife.
[unquote]
[end]


March 30, 2012 Notes:

The Community Spay Neuter Clinic operated by Dr. Stone in Freeport Maine opened in November 2010 and includes services for feral cats.

The website for the for Center for Wildlife Health Research [ http://cwhrbird.org ] is again not online at this time. I have a presentation (that I believe was hosted there) titled "Reducing wildlife predation by cats: Finding opportunities" by Allen Salo and Elizabeth Stone which includes these topics:

Educational experiences and views of veterinarians of indoor cat confinement by cat owners
and
Status and trends of feral cat colonies and TNR in Maine

The 2009 comment paper in Conservation Biology, "What Conservation Biologists Can Do Regarding Trap Neuter Return: Response to Longcore et al" which was hosted on the Center for Wildlife Health Research website when it was online and is hosted on the American Bird Conservancy website and elsewhere. http://www.abcbirds.org/abcprograms/policy/cats/pdf/Lepczyk-2010-Conservation%20Biology.pdf

cats are coyote prey > more anti cat / TNR from ABC

Several years ago, groups opposed to outdoor freeroaming cats and Trap Neuter Return or Release strengthened and rededicated their efforts with specific and collaborative strategies (notably but not only American Bird Conservancy, The Wildlife Society, US Fish and Wildlife Service.)

Today's ABC offering was a media release Studies Show Outdoor Cats Are Popular Prey for Coyotes
Well-meaning but misguided cat lovers are creating unsafe conditions for domestic cats by releasing them back into areas where they may become prey for coyotes and other predators,” said Darin Schroeder, ABC’s Vice President of Conservation Advocacy. “Owners who let their pet cat out into their neighbourhoods may be unknowingly ringing the dinner bell to unseen coyotes. We urge states, cities, and communities to reject this inhumane approach to the feral cat problem and instead, require responsible care of pets and the removal of feral cats from the wild."
As usual, it's picked up by various media outlets who generally accept whatever is included! Don't know why the press release above did not include a link to the current "study" mentioned . . .
A study just published in the spring edition of The Wildlife Professional, focuses on the urban coyote reality and references sightings of the carnivore in Central Park and Manhattan.
. . . but anyway, here it is: The Last Frontier: Eastern Coyotes in New York City
Anne H. Toomey, Mark Weckel, Chris Nagy, Linda J. Gormezano, and Scott Silver

Here's the 2009 version of ABC's press release Study Finds Outdoor Cats Easy Prey for Coyotes, Recommends Keeping Cats Indoors

Well-meaning but misguided TNR practitioners are creating unsafe conditions for domestic cats by releasing them back into areas where they may become prey for coyotes and other predators,” said Darin Schroeder, American Bird Conservancy’s Vice President of Conservation Advocacy. “Providing an all-you-can-eat buffet for coyotes is not a sensible solution and we urge states and communities to reject this inhumane approach to the feral cat problem and require responsible care of pets and the removal of feral cats from the wild.
The video mentioned in the press releases and today's news articles was released by ABC in May 2009.

While much of the anti cat/TNR information is biased and misrepresented, it is true cats are prey for coyotes and some people don't realize it. So the take away here is as I've urged numerous times before on Feral Cats in the News ~ the Feral Cat Blog! and on Cat Management in Communities or Community Cat Management:

Community Cat Management
A prevention AND solution action for cities, counties, communities is to immediately implement or support comprehensive cat management programs that promote CONCURRENTLY:


* spay neuter, identification, and containment as possible or supervision for 'owned' cats and
* Trap-Neuter-RETURN-Manage (TNRM) for unowned cats.
* covered dumpsters and garbage containers

Community Cats Trap Neuter Release Proposed Policy > American Public Health - Veterinary Public Health

see update at bottom

In 2010 the Veterinary SPIG (Special Interest Group) of the American Public Health Association (APHA) recommended that Trap Neuter Vaccinate Release be discussed as a preferred option for feral/stray cat management!

download pdf of the 2010 Veterinary Public Health TNVR resolution.

In 2010, 2011 and 2012 newsletters of the APHA Veterinary Public Health Section:

Spring 2010 APHA Veterinary Public Health Newsletter

. . . . . the trap neuter and release proposal (“Collaboration, not confrontation to manage feral and stray cat populations”) received a negative review by the APHA’s Joint Policy Committee (JPC). However, a very dedicated team of experts created an excellent appeal that answered the JPC’s concerns, and we are very optimistic it will receive a favorable review in July.


Fall 2010 APHA Veterinary Public Health Newsletter

MISSION
Speaking of projects, besides our obvious roles in zoonotic diseases, the most numerous suggestions for projects were:

c. Humane treatment of animals, including advancing TNR as a cat management program where possible. The Vet PH SPIG recommends TNR be discussed as a preferred option for feral/stray cat management.


Winter 2010 APHA Veterinary Public Health Newsletter

Proposed Resolutions:
A resolution is being considered for the endorsement of Trap-Neuter-Return (TNR) programs as the preferred management of stray and feral cat populations. More to follow pending SPIG discussion and consensus.


Fall 2011 APHA Veterinary Public Health Newsletter

Vet SPIG Members: Thought I’d update you on the status of our proposal to adopt trap-neuter-vaccinate-and-return, or TNVR, as a preferred public health measure to control free roaming community cats.
We first submitted our proposal in 2010, but it was rejected on the lack of compelling science. Our team of experts built a solid package for the appeal. However, the appeal was rejected but there was a comment that “you are close”.
We submitted an updated version earlier this year, but that was rejected mainly on wildlife concerns, and that some wildlife organizations opposed TNVR. This year’s appeal was also rejected despite the fact that our focus is public health. To assure that we have as complete a proposal as possible, I will send it for comment to the AVMA, other public health groups, and wildlife organizations.This active approach should, at least, focus the issues for and against TNVR.


Winter 2012 APHA Public Health Veterinary Newsletter

Lastly our proposal to adopt TNVR (trap-neuter-vaccinate-return) as the recommended approach to managing community cats will be fine tuned this coming year. We received outstanding input from the AAPHV, but will actively seek formal reviews from similar organizations to include the AVMA and the Wildlife Vets.

Another perspective on feral cat control
David A. Jessup, DVM MPVM DACZM and Elizabeth Stone, DVM MS in JAVMA Vol 237 No 5, September 1, 2010:


[excerpts, as always, read entire]

We disagree . . . . . that the human health risks associated with feral cats is low, and we know of no peer-reviewed research supporting this statement.

Over the past three years we have viewed with alarm a pattern of inviting advocates of TNR to national public health meetings and a steady refusal to include other perspectives.

March 30, 2012 Update: Dr. Court kindly replied that the Veterinary Public Health section of the APHA did not submit the policy in 2012, but have received constructive feedback and will resubmit in 2013.

Targeted Spay/Neuter: How, Why & Where to Find the Funding - Bryan Kortis, PetSmart Charities
Spaying and neutering works to reduce free-roaming cat as well as owned cat and dog populations, but only if it is done correctly. One key to success is properly targeting available resources, including spay and neuter surgeries, volunteers and funds. In this workshop, we’ll discuss why targeting is now the cutting edge in the Trap/Neuter/Return and spay/neuter fields, how to go about doing it effectively and applying for PetSmart Charities’ High Impact Spay/Neuter grants.

Feral or Frightened Cat? Research that Helps You Decide! - Dr. Margaret Slater, ASPCA
Do you have feral cats coming in to your shelter? Are you sure they aren’t just frightened? How do shelter professionals tell the difference between unsocialized or frightened but socialized cats? We will explore the problems in making these distinctions, and common methods of doing so in animal shelters. We will introduce new research results regarding the validity of these assessments, and share information to help your shelter decide how to handle your incoming cats to achieve best live outcomes for them.
Topics include:
Discussion of the issues in assessing cat socialization in a shelter setting
Results of a national survey on how shelters determine if cats are socialized
Research on the validity and ability to predict socialization using different assessments
The transformation of this validation work into a possible scoring system for use in shelters
Further efforts in this area to help shelters make this difficult decision

War and the No-Kill Movement
March 22, 2012 by Michael Mountain

The no-kill philosophy extends way beyond homeless pets. It’s a way of living that takes killing off the table – in every area once and for all. You can’t be no-kill and go hunting. You can’t be no-kill and be pro-abortion, pro-capital punishment or pro-vivisection. And you certainly can’t be no-kill and support going to war.

The Dynamics of Feral Cat Rescue and Management

"Alternatives to euthanasia, such as tame-and-home for feral kittens, and trap/neuter/return for adult feral cats, are increasingly popular. Many colonies have been managed by TNR for a long enough time to yield results on the factors that influence their success. Access to affordable spay/neuter, homing of adoptable cats and kittens, and dedicated monitoring of the colony will speed reduction of colony size. Adoption has become a vital component of TNR. Spay/neuter clinics and TNR-based groups have become members of Petfinder to place friendly stray cats and feral kittens in caring homes. This presentation will review the components of TNR and discuss results noted by caretakers and researchers."

Research Project: Quantifying the Spatial Distribution and Population Size of Feral Cat Colonies in Rhode Island as a Function Population Management Strategies


Summary: The increase in the size and number of feral cat colonies in the United States is a growing concern for public health officials, animal welfare organizations, wildlife advocates and the general public. Feral cats can carry zoonotic and infectious diseases that affect human, companion animal and wildlife health. In addition, wildlife advocates and management professionals are concerned about feral cats’ hunting behaviors having a negative impact on native bird, small mammal and reptile populations. To date, studies on feral cat population management strategies such as trap-neuter-release and trap-euthanize have been limited to a single, or small number of colonies, and have reported conflicting results.

The proposed study will provide baseline data on the locations of a representative sample of feral cat colonies in Rhode Island, an estimate of their current populations, and the management approach, if any, used for each colony. Locations of feral cat colonies and associated management strategies will be identified by conducting interviews with individuals with knowledge of the specific feral cat colonies in Rhode Island. Using a Geographic Information System (GIS), a statewide map of the location and spatial distribution of representative feral cat colonies will be developed. A Lincoln-Peterson Index will be used to estimate population size at each colony, where animals visually identified on day 1 are treated as “marked,” since no physical capture of animals is planned. Thus, animals seen on day 2 that were not detected on day 1 would be assumed to be “unmarked.” The L-P index uses the ratio of marked to unmarked animals to estimate population size. The GIS maps will be amended to include estimates of feral cat colony population size based on L-P indices. In addition, estimates of cat density (cats/mile2) per colony’s home range will be provided for select colonies around the state (exact methodology will be discussed and further refined with the RI Feral Cat Working group). Descriptive statistics of the colony data by management approach will be calculated using SPSS release 18.0.0.

This information will be used in a subsequent study in 2012 to evaluate the efficacy of the various management approaches applied, and ultimately develop a comprehensive evidence-based recommendation for feral cat colony management in Rhode Island. Given the absence of any similar comprehensive, statewide evidence-based analysis of this issue, other communities dealing with feral cat management issues may benefit from the findings of this research.

I am checking to see if Yes, the Dr. Scott Marshall listed as a mentor for this project is the same Dr. Scott Marshall who is the State Veterinarian, Rhode Island Department Division of Agriculture, Department of Environmental Management.

In February 2010, there was proposed legislation in Rhode Island to euthanize feral cats. According to news articles, "State veterinarian Scott Marshall brought the proposed legislation to Tassoni in mid-February as a method to improve the free-roaming, feral cat problem in the state." In March 2010, Senator Tassoni dropped the proposal.

For those unaware, "The One Health Initiative is a movement to forge co-equal, all inclusive collaborations between physicians, osteopaths, veterinarians, dentists, nurses and other scientific-health and environmentally related disciplines, including the American Medical Association, American Veterinary Medical Association, the American Society of Tropical Medicine and Hygiene, the Centers for Disease Control and Prevention (CDC), the United States Department of Agriculture (USDA), and the U.S. National Environmental Health Association (NEHA). Additionally, more than 600 prominent scientists, physicians and veterinarians worldwide have endorsed the initiative."
"The One Health concept is a worldwide strategy for expanding interdisciplinary collaborations and communications in all aspects of health care for humans, animals and the environment. The synergism achieved will advance health care for the 21st century and beyond by accelerating biomedical research discoveries, enhancing public health efficacy, expeditiously expanding the scientific knowledge base, and improving medical education and clinical care. When properly implemented, it will help protect and save untold millions of lives in our present and future generations."

Kitty Cams Research Project Update

[excerpt]

GENERAL RESULTS
We had enough footage from 55 of our participating cats to analyze. Thanks to our diligent volunteers, we had an average of 37 hours of footage per roaming kitty. One of the most surprising things we witnessed was cats adopting a second set of owners. Four of our project kitties were recorded entering another household for food and/or affection!
Results indicate that a minority of roaming cats in Athens (44%) hunt wildlife and that reptiles, mammals and invertebrates constitute the majority of suburban prey. Hunting cats captured an average of 2 items during seven days of roaming. Carolina Anoles (small lizards) were the most common prey species followed by Woodland Voles (small mammals). Eighty-five percent of wildlife captures were witnessed during the warm season (March-November in the southern US). Twenty-three percent of cat prey items were returned to households, 49% of items were left at the site of capture and 26% consumed. Cats roaming during warmer seasons were more likely to exhibit hunting behavior and the number of captures per hunting cat is expected to decrease with increasing cat age. Cat age, sex, and time spent outside did not significantly influence hunting behavior.
The most common risk factors experienced by suburban free-roaming cats include: crossing roads (45% of our sample), encountering strange cats (25%), eating and drinking substances away from home (25%), exploring storm drain systems (20%) and entering crawlspaces where they could become trapped (20%). Eighty-five percent of project cats were witnessed exhibiting at least 1 risk behavior. Male cats were more likely to engage in risk behavior than female cats and fewer risk behaviors were witnessed by older individuals. Total time spent outside also influenced the number of risks experienced by free-roaming cats.

Domestic cats (Felis catus) are extremely efficient and abundant suburban predators. The predation rate of the domestic cat remains a topic of considerable social and scientific debate and warrants attention using improved methodology. Previous predation studies relied on homeowner reports of prey take and other indirect methods. We monitored the activities of 60 owned, free-roaming cats in suburban Athens, Georgia over a one year period (Nov. 2010- Oct. 2011) using Kitty Cam video cameras. Kitty Cams allow recording of an animal-eye view without disrupting behavior. Each participating cat wore a video camera for 7-10 total days and all outdoor activity was recorded for analysis. Specific research goals included: 1) quantifying the frequency of cat interactions with native wildlife 2) identifying common prey species of suburban cats 3) investigating risk behaviors experienced by roaming cats and 4) examining predictors of outdoor behavior. Preliminary results indicate that a minority of roaming cats hunt wildlife and that invertebrates and reptiles constitute the majority of suburban prey. Additionally, owned, free-roaming cats in Athens only bring a few of their prey back to their households; most is consumed or left at the site of capture. The most common risk behaviors exhibited by roaming cats include crossing roads, approaching other cats and exploring storm drains. Demographic factors did not influence hunting behavior but were predictors of risk behaviors. The Kitty Cams project aims to contribute reliable statistics and irrefutable images to the growing debate over free-roaming cats in the environment.

[excerpt]
We currently have video analysis complete for half of our 60 participating cats. Preliminary results suggest only 30% of roaming pet cats hunt. Thus far, the most common prey types of Athens' kitties are reptiles followed by invertebrates (insects). We suspect this may differ by season though. Most cats experienced at least one risk while roaming their neighborhoods. Common risk behaviors include: crossing roads, exploring storm drains, entering crawlspaces where they could be trapped and encountering other cats. A report presenting full results of the kitty cams project should be available late Spring 2012.

ABSTRACT

Despite extensive worldwide surveillance in populations of both people and wildlife, relatively little is known about Toxoplasma gondii ecology in the circumpolar north. Many northern animals and people demonstrate exposure to T. gondii, but the apparent low densities of domestic or wild felids suggest that additional transmission mechanisms are responsible for T. gondii persistence in high latitudes, whether remote source (from another region), vertical, or dietary. People in these northern communities who practice subsistence hunting might have an increased infection risk due to traditional food preparation techniques and frequent handling of wild game. Recent advances in T. gondii genotyping, understanding of host–parasite relationships, and increased human and wildlife surveillance will help to address knowledge gaps about parasite evolution, distribution, and abundance throughout the Arctic and Subarctic.

Feral Cat Blog! Notes:

The two presentations above contain similar content to other FWS material that AnimalResources has previously provided to leading cat advocates nationwide such as the Florida Keys Integrated Predator Plan, other presentations by Morkill and Hughes, and by Tom Will of FWS Midwest Migratory Bird. In recent years, increasing and rededicated efforts have been made in opposition to feral and free roaming or unrestrained cats and Trap Neuter Return by Tom Will and other FWS staff, several leaders of the American Bird Conservancy and The Wildlife Society, and others.


In August 2011 AnimalResources shared info with leading cat advocates nationwide about a Florida Keys Predator Study regarding free roaming cats, a $300K contract awarded by FWS to the Cooperative Fish and Wildlife Research Unit, Dept. Biology, NC State University, Raleigh, NC. The project lead is Ted Simons. In January and August 2011 AnimalResources provided the list of research needs for priority species in the Florida Keys (marsh rabbit, cotton mouse and woodrat) relevant to feral or free roaming cats as outlined in an RFP of the USFWS Southeast Florida Ecological. These are significant because for years, FWS has planned and attempted to trap and remove free roaming cats in the Florida Keys Refuges without a clue about the number of cats or endangered species involved.


For those unaware, there are mind-numbing multi-layers of US Department of Agriculture and US Department of Interior government agencies and organizations and their projects, programs, partnerships, initiatives, training, relationships and funding: federal and state fish, wildlife, hunting agencies and nonprofits related to those; other bird, conservation, wildlife nonprofit organizations; and state land grant universities (agriculture and forest research, Extension, etc, Hatch Act of 1887 research funding, Cooperative Research Units) and much more!

Abstract
Poland's Animal Protection Act, as of 2002, made it legal to shoot free-ranging cats and dogs. The act triggered substantial social debate with opponents arguing that this legislation was weakly supported by scientific evidence of the ecological impacts of free-ranging pets. Our main research goal was to examine the activity of free-ranging domestic cats within a Polish protected area by applying radio-telemetry methods to determine space use and degree of encroachment into the national park. We trapped and radio-tracked 19 animals from three sites (focal households) located in Ojcow National Park (ONP) in southern Poland from June 2003 to March 2006. Annual 100% MCP home range size varied from 0.02 km2 to 1.46 km2, and was significantly larger for males (mean ± SE = 0.79 ± 0.34 km2; median = 0.53 km2) than for females (mean ± SE = 0.13 ± 0.05 km2; median = 0.13 km2). The distance travelled by individual cats from focal sites did not significantly differ between males (mean ± SE = 232.00 ± 21.05 m; median = 191 m) and females (mean ± SE = 232.50 ± 12.47 m; median = 228 m), with maximum distances of 1.5 km for males and 1.1 km for females. All monitored cats were in close proximity to nature reserves and ranged into protected areas without any human control. Cats living in the households in the park and its surrounding buffer zone, roaming at 200 m and 1000 m radius distances from their households, occupied from 6% to 100% of the park area, respectively. Our results reveal that free-ranging domestic cats roam through and potentially impact the entire national park, thus reducing its effective protected area.

PROGRESS: Jan 1, 2011 TO Dec 31, 2011

OUTPUTS: I have been examining how federal land management agencies have circumscribed their range of management options by clinging to regulations that are unnecessarily narrow interpretations of statutory language. As climate change alters landscapes and ecosystems agencies will need more, not fewer, management choices in order to meet their legal obligations. I am working on a comprehensive review paper that will target a more general audience and which will synthesize all of the work I have done to date on predator control, intensive management, and federal-state conflicts on wildlife management in Alaska. I hope to have this manuscript in a form ready for submission by spring 2012. I have begun a research project examining the conflict between federal migratory bird protections and state and local ordinances protecting feral cats which are often a major source of bird mortality. This work is being carried out in cooperation with Nell Fuller of the US Fish and Wildlife Service.
PARTICIPANTS: I am working with Nell Fuller of the US Fish and Wildlife Service on the project examining conflicts between migratory bird protection laws and feral cat protections.
TARGET AUDIENCES: The target audiences for all of this work are land, resource, and wildlife managers at the federal and state levels, as well as the legal community that serves those sectors and the members of the public interested in those issues.

IMPACT: 2011-01-01 TO 2011-12-31 The examination of federal land management strategies in the face of climate change will have broad appeal to the land and wildlife management communities as well as the legal community that serves those sectors. While there is an ongoing push to amend existing land management laws or pass entirely new ones so that the law more directly acknowledges and addresses the challenges brought by climate change, such legislative change is still in the distant future. That means that at present the most effective changes will have to be made at the agency/regulatory level. This review paper will bring this body of work more readily into the hands of land and wildlife managers and agency policy makers. I hope that the final product will be very accessible and therefore useful to those individuals faced with these questions and conflicts everyday. Numerous published, scientific studies have demonstrated that feral cats kill millions of birds each year in the U.S. When birds are listed by the US Fish and Wildlife Service as threatened or endangered, feral cats are often named part of the problem. Yet many state and local governments protect and even perpetuate feral cat populations. This work should be useful to wildlife and land managers and advocates struggling with balancing these various legal obligations.

Models simulating the predatory pressure of domestic cats

Development and credibility testing of individual-based models, simulating the predatory pressure of the domestic cats (Felis catus)
Jannick Hansen
Department of Bioscience, Aarhus University, Aarhus, Denmark
M.Sc. Thesis January 2012
Master’s Thesis in Biology Manuscript draft aimed for publication in Ecological Modelling

Abstract

Even though the domestic cat (Felis catus) is an abundant predator in many parts of the world, little is still known about the actual impact that domestic cats have on prey species. Studies have shown a great variation in the expected impact on prey species, and this variation can to a high degree be explained by spatial variations, as the local distribution and densities of both cat and prey have a markedly affect on cats predatory pressure.

This study has incorporated the spatial complexity of the domestic cats hunting pressure, by developing and testing three individual-­-based domestic cat predation models, with increasing complexity. The purpose was to evaluate both the need for complexity and the usability of the best model in reliably assessing the predatory pressure of domestic cats.

Development and testing was based on available literature data concerning important factors linked to cats predation pressure. Data for testing was primarily sourced from an urban and suburban study in Dunedin, NZ, which contained data of cats home range sizes in addition with estimates of the city-­-wide catches and the proportion of cats contributing to the catch numbers.

The results showed an improved ability to recreate the Dunedin scenario with added complexity to model behaviour, although it was not possible for any of the model types to decrease the deviation between the model output and the Dunedin observations, to a reasonable extent. The difficulties in improving the models compared to the test scenario, is very likely to be a result of inaccuracy in the key assumptions for the model simulations. The developed model does, however, still provide a useful purpose, as it can offer rough evaluations of cats hunting pressure. Moreover, it is spatially flexible and, as opposed to conventional extrapolation methods, can be applied in a wide range of possible scenario types. Reliable and testable data of domestic cats hunting pressure is, however, needed before a more accurate evaluation of an individual­-based cat predation model can be attempted.
