2Paper Objectives
- Characterize translocation in the U.S.
- Describe substantial challenges of attempting to
curtail translocation related to human-wildlife
conflicts
3Why Relocate Animals?
- Reintroduction of rare or extirpated species
- Enhance populations of game species
- Reduce wildlife conflicts
4Translocation The transport and release of wild
animals from one location to another with
emphasis on nuisance and damage. (Craven et al.
1998)
5Round One in1998..
6Translocation
The wildlife management profession should
minimize or eliminate translocation where
possible.... -Craven et al. 1998 Wildlife
Damage Working Group The Wildlife Society
7Translocation
Any translocation of nuisance raccoons,
foxes, or skunks is inadvisable.... -Craven et
al. 1998 Wildlife Damage Working Group The
Wildlife Society
(meso-carnivores)
8Translocation
Guidelines should be developed to improve the
success of translocations....and to minimize
related problem -Craven et al. 1998 Wildlife
Damage Working Group The Wildlife Society
9Tackling Translocation is a Big Job
- The number of
- common species
- moved around the
- landscape.. is
- probably in the
- hundreds of thousands
- nationwide.

- Barnes (1995)
- Curtis et al. (1993)
- -Craven et al. (1998)

10The Question..
Are there right answers in these discussions,
given the many interrelated aspects of animal
welfare, human emotion, and professional ethics
involved? -Craven, Barnes and Kania (1998)
Translocation
11Changing Human Values
Urban Challenges
Patchwork of Laws
12Focus on Translocation to Reduce Conflicts
(Primarily meso-carnivores)
13Time is ripe for reexamining the issue..
14- State and Federal
- Wildlife Agencies
- Renewed Interest
- Related to International
- ORV program
"The Buzz"
15Primary Concerns with Translocation
- Spread of disease
- -Wildlife, Agriculture, HHS
- Rosatte (2002)
- Will jeopardize the national ORV program.
16Primary Concerns with Translocation
- Humane aspects of
- translocation including stress and mortality
of animals.
Rosatte and MacInnes (1986) Barnes
(1995) Hadidian et al. (2001) Rosatte
(1989) Rosatte (2002) Adams et al. (2004)
17Primary Concerns with Translocation
- Impact to resident animals at the release site.
Obviously when we discuss animal welfare
concerns, we must consider the welfare of of both
resident and relocated animals. Schmidt (1995)
18Primary Concerns with Translocation
- Movement of problem or rehabiltated animals where
they will continue to be (or create) a problem.
19All opposed (or at least mostly opposed) ..Say
Nay

late 1970s

Landowners?
26- Private Land Holders
- .. 69 of the States allow relocation by
personal - property owners. -La Vine et al. (1996)
- Approximately 25 of respondents attempted to
- control the nuisance situation themselves before
calling - a NWCO firm (about 5 tried live trapping)
- -Braband and Clark (1992)
27Informal discussion with leading box trap
manufactures
- All 3 companies reported increase sales last 5
years - (10-100 increase).
- Raccoon and squirrel
- sized traps most popular
- Conservative estimate of 700,000 box traps sold
annually in U.S.
28Growth of an Industry

- Curtis et al. (2003), Julien et al. (2003)
Number of NWCOs in Connecticut
29Designated private agents are allowed to
euthanize nuisance animals for property owners in
39 states (95) while 32 states (91) allow such
agents to relocate nuisance animals. -La Vine
et al. (1996)

38Conclusions and Lessons Learned
39 Translocation is Bad!
Box-O Raccoons
Remains a tough issue in a sea of tough
professional issues.
40LL 1. Need for More Professional Dialogue
41LL 2. Laws Alone Wont Help
Laws Education Enforcement Reduction in
Translocation
42LL 3 Need for More Realistic Management
Approaches to Address Translocationin Urban
Areas
- Alternative methods of euthanasia needed
43LL 4 All Management is Local, but Cooperation,
Coordination and Standardization Remains Essential

Reducing Translocation
44LL 5. Multiple Opportunities for Research
- Fate of translocated animals
- Impact on resident populations
- Human dimensions (public, industry, rehab.)
- Summary data on laws, policy enforcement
- Documentation of landowner impacts
- Documentation of coursing pen impacts
- Enhanced techniques for euthanasia
- Summary data NWCO, Rehabilitators
45Conclusions
- Time is ripe for more discussion
- Focus on meso-carnivores
- Tackling translocation will require a combination
of approaches - Urban challenges will require creativity
- Fill data gaps to spotlight issue
- Remains Priority Issue for Rabies Management
