  1. Internet Survey of Current Deer Management Issues The Western Section of the Wildlife Society February, 2012 G. Kent Webb San Jose State College of Business Ph.d., M.B.A., M.S.E.

  2. Goals: Create a searchable collection of the most current deer information to support research and management. Increase public awareness of deer issues Support academic research in the use of the Internet to support decision making

  3. Tools Google Search and Google Alerts - Over 200 articles per day from Google Alerts using various “deer” keywords - Seeing most content that pops up Google Sites - Web hosting tool well integrated with Google tools - Advertising on news pages almost pays for hosting and internet costs

  4. Tools

  5. Distribution of Significant Information Deer Hunting: 25 % General Management: 19 % Urban Deer Management: 17 % (most decisions, growing number of stories) Deer Vehicle Collisions: 16 % Deer Resistant Plants: 7 % Disease of Deer: 5 %

  6. News Threads for Presentation Decline of Western and Other Deer Populations Predator Management Hunter Management Efforts to Reduce Deer Vehicle Collisions Litigation and Legislation Urban Deer Management Powerpoint presentation available at, link at upper right

  7. Decline of Deer Populations (references, last slide) Deer Friendly Forests (1) California Graphic 1984 CDFG (2) The California deer population has plummeted over the past two decades ( - 50% +) (3) (Thanks Dave Smith, CDFG)

  8. Decline of Deer Populations California: Siskiyou county first to propose changes to deer tags “ … the deer are just hammered” (4, Feb. 2011) No doe hunts in Butte, Colusa and now Yuba counties, but deer population continues to decline (5, Jan. 2012), perhaps 30 % in last several years Wildlife biologists report some increase in deer populations along Sacramento River in Feb. 2010 (6)

  9. Decline of Deer Populations California: ...“The herd has been stable,” [Randy] Botta said there are between 5,500 and 6,200 deer on public, “huntable” land in San Diego County, after years of decline (7) Dr. Steven White, of the San Jose State University Department of Biological Sciences, takes DFG to task over eliminating the refuges without suggesting an alternative to help the declining deer population in the state. (8) In 2010, CDFG begins study in 2010 Mendocino, Glenn and Lake counties

  10. Decline of Deer Populations Nevada About 50,000 mule deer in Nevada, down from a few hundred thousand a few decades ago Some on the Nevada Wildlife Commission think the mule deer could become extinct in the state Cut deer tags 22 percent in 2011 (9) Hawaii Plans to eliminate deer, invasive species

  11. Decline of Deer Populations Alaska reports slow recovery (10) Washington: few fawns, deer population down by 25 % in 5 years in some areas, decrease in logging since 1990 (11) Oregon: Declining herd over 5 years, problems in north, 2011 number of deer shot up 14% (12) Idaho: Lowest fawn survival rate since 1998 among radio collared fawns, 26%, harsh winter, average is 60% (13)

  12. Decline of Deer Populations Utah: Number of deer tags reduced by 7,000 in 2011 out of concern for declining deer population (14) Arizona: Antelope fawn survival, few to none. Game and Fish suspect predation, conducting study (15). Deer herd about stable. Montana: Mule deer counts down 35 % in some regions at end of 2011 (winters, predators, oil development) (16)

  13. Decline of Deer Populations Wyoming: Officials looking for ways to grow the herd, 20 to 30 percent declines over 5 to 10 years in many areas (increased oil and gas drilling an issue) (17) Colorado: Mule deer down by up to 36 percent in northern mountains in 30 years, NWF study concludes that herds across Colorado and southern Wyoming "may not be able to fully recover ”without protection (18)

  14. Decline of Deer Populations North Dakota: harsh winter, few fawns”… they're just not able to bring the fawn to birth ... they will reabsorb the fetus and use the energy to stay alive (19). Maine: Population crash, precipitous decline in last four years. Habitat, harsh winter, and coyotes. Fish and Game changes policy against feeding deer and offers how-to instructions (20) South Carolina: Decline in deer population results in a proposal to reduce buck limit in state with most liberal limits. Coyotes and forest (21)

  15. Decline of Deer Populations Texas drought has decimated fawn production. - Deer killed in hunts were in better shape than expected (22) - Does miscarried or abandoned fawns they could not feed (23) - Starvation not a necessary condition for a dramatic fall in population based on food supply - Another drought on the way - Disease is wiping out the oak trees, Chestnut blight destroyed all trees in NE by 1942, 50 miles a year (also in CA, sudden oak death) (24)

  16. Decline of Deer Populations How accurate is the data: Not Very A Michigan hunter blog asserts that at least 50% of the deer kills are illegal (25) "Estimating the number of deer you have is the La Brea Tar Pit of deer managment"  Dr. James Kroll, new Deer Czar of Wisconsin (26)

  17. Predator Management Hunters think it’s the lions

  18. Predator Management Michigan: Wolves hunted as of Jan. 27, 2012 - Reduced logging in the Upper Peninsula almost certainly had a greater impact on deer populations than wolves (27) Wolves also hunted in: Idaho, Montana, Minnesota California: First wolf since 1924 around Dec. 29 - Two year old male with a tracking collar crosses from Oregon (tracked online DFG Map) (28)

  19. Predator Management Virginia: Coyote and Wolf Hybird Deer populations are down in parts of Virginia as a result of coyote predation Coyotes entered from the north and bred with wolves along the way (Smithsonian) (29) Youtube video (30) Two coyotes (hybrid?) take down a large buck in Oklahoma

  20. Predator Management New York: Preliminary findings show coyotes have little impact on adult deer survival rates (92 percent were scavenged remains) but they do impact the fawn population (34 documented coyote kills). One collared female coyote with seven pups killed 10 fawns during a three-week period... (31)

  21. Hunter Management Texas: "The universe of deer hunters is on a spiral downward," "I've spoken with outfitters and seen other analyses that support my theory that fewer young adults are electing to join the field of deer hunters." Texas PWD Executive Director Carter Smith ..."A new age of outdoors-inclined folks are joining the party. Some have never hunted or fished before, but love the outdoors, and their focus may be on other things, like biking, photography and canoeing,“ (32)

  22. Hunter Management Washington: Number of hunters down significantly in 2011 (jj) May approve more expensive multiple-season permits (33) Idaho: Deer and elk tag revenue down $3 million since 2008 (34) Utah: Number of tags has been falling since the Mid-1980s (35) Arizona: Applications for big-game hunting permits have fallen 22 percent since 2006... Arizona still gets far more applications than it can approve (36)

  23. Hunter Management A trophy mule deer in the Trans-Pecos (Texas) averages $4,500 and management bucks average $3,000 (36)Management buck, $1,000 top trophy $7,500 (38) Minnesota DNR tries to raise hunting fees again in 2012, turned down in 2011, no increase since 2000 (39) California: Resident deer tag $29.16 Non-resident: $255.96

  24. Map shows where people are taking pictures of deer and posting on internet. Click on icons for pictures Deer Vehicle Collisions CDFG begins collar and video monitoring of deer after young Stanford grad and Santa Clara professor dies after he gets out of his car on I-280 after striking a deer. About 100 deer hit per year along a 13 mile stretch north of Woodside. (40) Map icon density predicts location U of Alberta study: collision sites formed “fairly striking patterns”: - high speed limits - high vegetation right up to the roadside (41) Davis researcher Shilling ... is among those who chastise Caltrans for continuing to build concrete median barriers on freeways and highways. The barriers can act as a trap,(42) Map does not reflect overall deer density

  25. Deer Vehicle Collisions Insurance Studies: Third year of decline in U.S., down 7% from 2010, fewer miles in recession suggests State Farm (43). Some suspect deer adapting Deer Hunting and Vehicle Collisions: Opening day and opening Saturday of hunting season are “two of the most dangerous days to drive.” in Pennsylvania Missouri Insurance Information Service, increased deer activity associated with hunting is a "major factor" in the rise in deer-vehicle collisions in the last three months of the year. (44)

  26. Deer Vehicle Collisions Utah: Wins design award for U.S. 6 reduction in collisions “Ninety percent of the success of a wildlife crossing is location ...“ Patty Cramer, USU Researcher. (45) A new type of snow fencing on State Road 73... a local resident comments: ."The fencing has limited open slots and miles of solid wall… wherever there is a slot in the fencing, you'll find a dead deer on the highway." ... Mindy Nelson, a UDOT spokeswoman, said UDOT was not aware of a deer situation. (46)

  27. Deer Vehicle Collisions Maryland: University research using critter cams shows deer and other animals will use storm drains, much smaller than expected, to avoid traffic. Does seem to be showing fawns (47)

  28. Deer Vehicle Collisions Despite a 34 percent increase in the Rochester Hills deer population since 2009, the city experienced a 25 percent reduction in deer-vehicle crashes The decline was up to five times greater than that seen in neighbouring areas, which did not use the signs and "Don't veer for the deer" campaign (48)

  29. Deer Vehicle Collisions ... A birth control injection for deer puts them completely out of the mood to mate for up to five years without a booster.... GonaCon ... eliminates dangerous and destructive courtship behaviors responsible for the autumn increase in collisions between cars and deer (49) … planning to extend a stretch of roadside reflectors … meant to curb night-time car-deer collisions, citing the apparent success of the experimental system (50)

  30. Litigation and Legislations Litigation: Courts are looking at the science Alaska Headline: Court confirms: US Forest Service flubbed science by allowing logging in Tongass (52) Sierra Club argues Utah regulators illegally approved a mine near Bryce Canyon mine by ignoring the damage, a major migration corridor used by a mule deer herd. The Utah Supreme Court is expected to hear the case in late 2012. (52)

  31. Litigation and Legislations New York: Binghamton University must conduct an impact analysis that will be reviewed by courts before conducting a deer cull (53)

  32. Litigation and Legislations Legislation Wisconsin: the Wisconsin State Assembly approved a bill to eliminate the Department of Natural Resources' earn-a-buck program (54) Pennsylvania HB 2034 is a legislative attempt to remove deer management from the control of the Pennsylvania Game Commission and put it into the hands of hunters and legislators (55)

  33. Urban Deer Management Often cited as the most contentious issue facing local governments Missouri: Residents Line Streets to Protest Cull - 2008 poll shows 68 % of residents oppose deer cull (56, January, 2012) (Town and Country relocation in Journal of Wildlife Management) New York: “Deer Harvest Down” - deer are not being taken in the woods because they’re not in the woods. ... “They’re in everybody’s backyard. They’re not stupid … (57)

  34. National News Cull decision still under appeal, April 25, 2011 in courts most of the 2011. Also Binghamton University, Judge will review Environmental Impact Study.

  35. Urban Deer Management Youtube video of deer going after dog in suburbs leads to a series of deer culls in British Columbia (58) British Columbia wildlife biologist suggests tightened leash laws one reason deer are entering suburbs, and that trained herding dogs could be used to create deer aversion to suburbs (59) Some cities in Canada are experimenting with the approach, some success (60)

  36. Urban Deer Management

  37. Urban Deer Management Center for Disease Control and Disease Ecologists conclude a deer cull is generally not shown to be effective against Lyme - deer are a host for ticks, not for Lyme - at least 125 other hosts for ticks, many of which transmit Lyme - deer eat tick habitat, some studies show deer reduce incidence of Lyme (61) This information has not spread to many local wildlife managers (62)

  38. Four-poster system reduces tick populations (63) did not increase vehicle collisions no increase in direct contact Tick Extermination, a job for deer
