Introduction
The Deer Project conserves and manages native white-tailed deer and the exotic
sika deer. The goals of the Deer Project are to ensure the present and future
well-being of deer and their habitat; maintain deer populations at levels
necessary to ensure compatibility with human land uses and natural communities;
encourage and promote the recreational use and enjoyment of the deer resource;
and inform and educate Maryland citizens concerning deer biology, management
options, and the impacts that deer have on landscapes and people.
The Maryland Department
of Natural Resources (DNR) utilizes broad-based deer management techniques to
meet these goals. Hunting remains the most cost-effective population control
mechanism available in most Maryland landscapes. DNR employs a blend of hunting
related deer management methods and proven non-lethal deer management
techniques. Maryland Deer Project staff annually attend deer conferences to
exchange information regarding any experimental initiatives for suburban and
urban locales. This broad-based philosophy of deer management ensures a
comprehensive long-term management approach.
Maryland Public
Attitudes Regarding Wildlife Management
Deer management through hunting is most effective when the public supports
hunting. A 2003 scientific survey conducted by Responsive Management indicated
that 78% of Marylanders approve of hunting. Eighty-five percent of Maryland
citizens agree that hunting and fishing are part of scientific management for
healthy fish and wildlife populations. In addition, the same survey found that
9 out of 10 Marylanders rate Maryland DNR biologists as credible for information
regarding wildlife.
Deer Hunting
Economics
Every 5 years, the U.S. Fish and Wildlife Service conduct a nationwide survey of
fishing, hunting and other fish and wildlife recreational activities. The most
recently published survey (2001) documents the growing positive economic benefit
of deer hunting to Maryland.
Retail sales of deer
hunting equipment and supplies produced $82.3 million for Maryland's economy.
When this initial spending is multiplied by the accumulative effect to the
economy, the total rises to $156 million. Both totals increased by over 100%
from the 1996 survey. Total payroll and profits spawned by firms affected by
Maryland's deer hunting industry topped $37 million, a 65% increase over 1996
figures. Over $4.1 million in Maryland sales tax is collected due to Maryland
deer hunting. The deer hunting industry in Maryland contributed $1.4 million in
Maryland state income taxes and $6.3 million in federal income taxes.
White-tailed Deer
History
Prior to the arrival of European immigrants, white-tailed deer inhabited all of
Maryland and eastern North America. Native Americans hunted deer during all
seasons. In Maryland, wolves and mountain lions preyed on all age classes and
sexes of white-tailed deer.
The first European
settlers in Maryland found ample white-tailed deer populations. Deer meat and
hides provided them with food and clothing. Venison recipes from those early
settlers have been passed down through generations.
As the colony prospered
and human populations multiplied, unregulated market hunting and the destruction
of habitat (deforestation) caused deer populations to decline drastically
throughout the 1700s. Market hunters sold deer meat to colonists and shipped
deer hides to England's booming leather industry. With settlements expanding
across the state during the 1800s, deer populations continued to drop, and
mountain lions and wolves were exterminated. By 1900, white-tailed deer only
inhabited limited sections of far Western Maryland.
Since the birth of
wildlife management in the early 1900s, Maryland's deer population has expanded
into all habitats. State wildlife biologists, working hand-in-hand with private
citizens, restocked the white-tailed deer to all available habitats in the
state. Some native deer were trapped in Western Maryland and released into
unoccupied habitat. A few deer were obtained from other states and released
across Maryland. The majority of deer stocked after World War II came from a
large population inhabiting Aberdeen Proving Grounds in Harford County. Deer
relocation efforts ended in the early 1960s as all unoccupied deer habitat was
stocked.
Early hunting seasons of
the 1930s and 1940s prohibited the taking of antlerless deer in order to allow
for the continued growth and expansion of relocated deer herds. As deer numbers
climbed and all deer habitat became populated, deer seasons and bag limits
became more liberal. Across Maryland, current deer seasons and bag limits
encourage the harvest of antlerless deer in order to manage deer populations.
At the same time, these regulations encourage hunters to be more selective with
antlered buck harvest.
Since white-tailed deer
thrive in habitat that is composed of woods and openings, the expansion of
housing developments into forests or onto farms provides excellent white-tail
habitat. Streets and home sites created in a wooded area produce habitat
preferred by white-tailed deer. Open farm fields become better deer habitat as
new homeowners plant trees and shrubs on their bare home site. Deer populations
have escalated in these suburban landscapes where exceptional habitat is
available and hunting becomes limited.
Sika Deer History
Maryland sika deer are originally from Yakushima Island in southern Japan and
can be found in the marshes, swamps and associated woodlands, and agricultural
fields in portions of the lower Eastern Shore. Populations exist mainly in
Dorchester County and on Assateague Island in Worcester County. However,
harvest data and reported sightings indicate that sika deer are slowly expanding
into similar but more limited marshy habitat in portions of Caroline, Somerset,
Talbot and Wicomico counties.
Sika deer became
established on the lower Eastern Shore after being released by Clement Henry on
James Island (Dorchester County) and by Dr. Charles Law on Assateague Island
(Worcester County) during the early 1900s. Exactly how they initially made
their way from Japan to the Eastern Shore is unknown. The small number of sika
deer in the original stock (approximately 6 individuals) has resulted in
relatively low genetic variability within the population today. However,
Maryland sika deer display no ill effects from the small founder population and
appear as healthy or healthier than native white-tailed deer. Currently, DNR's
sika deer management goal is to maintain this exotic species at current levels
so that hunting opportunities are balanced with agricultural depredation and
whitetail competition issues across the lower Eastern Shore.
Sika deer hunting is
very popular in Dorchester County and on Assateague Island. Nonresidents and
hunters from other areas of Maryland now travel to the lower Eastern Shore with
hopes of taking a trophy sika stag of 6 to 8 antler points. Professional guide
services are available that cater exclusively to sika deer hunters. Based on
recent 5-year averages, approximately 7,000 hunters pursue sika deer with
firearms each year for an average of 4.1 days per year. About 4,600
muzzleloader hunters stalk sika deer each year for 3.6 days per year.
Similarly, approximately 3,700 bowhunters pursue sika deer each year for an
average of 6.9 days per year. After 2 years of crossbow sika deer hunting,
hunter surveys indicate that an average of 327 hunters stalked sika deer with
crossbows.
Past biological data
collected by DNR indicate that the average field-dressed weight of a 1.5
year-old male sika deer averages 53 pounds, while 3.5+ year-old males top 80
pounds. Sika stags that were 3.5+ years of age averaged 5.5 antler points,
while 2.5 year-old deer had 4.1 points. Field-dressed yearling (1.5 years old)
females averaged 45 pounds with 3.5+ year-old females weighing about 60 pounds.
Sika deer tend to use
different habitats than native white-tailed deer that share the same area.
Although home range sizes are similar between the 2 species, sika deer use
forested wetlands, marshes, and the interface between these 2 habitats much more
than white-tailed deer. Sika deer do not appear to rely on agricultural lands
like white-tailed deer do. It is unknown whether sika deer prefer the forested
wetlands and marshes of Dorchester County, or if competing white-tailed deer
relegate them there.
Previous DNR research
confirmed that sika deer have lower reproductive potential than white-tailed
deer. Sika females tend to bear a single calf while white-tailed females over
1.5 years old frequently bear twin fawns. DNR's research found that about 25%
of sika female fawns were pregnant while up to 50% of white-tailed female fawns
had bred. Currently, DNR is conducting a pilot study on Assateague Island to
see if radio transmitters can be effectively used to locate newborn calves to
further our knowledge on sika birth rates and calf survival.
Sika deer in Maryland
appear to be long-lived compared to white-tailed deer. Tagged individuals from
previous research studies have been harvested or observed 10+ years after they
were initially captured. Numerous sika deer aged by DNR staff often have teeth
worn below the gum line indicating significant age. One sika female was aged at
20+ years using the cementum annuli aging technique. The longer life span of
sika deer may result from their use of habitat that is more difficult to hunt,
thus, not as many are harvested each year as compared to white-tailed deer. As
more information is collected on sika deer in Maryland, it becomes apparent that
more research is needed to understand their life history traits and the role
they play in the ecosystem. Food habits, timing of reproduction, and calf
survival are several of the questions to be addressed in future studies.
2006-07 Deer Hunting
Regulation Changes
New regulations aimed at preventing
the spread of Chronic Wasting Disease (CWD) were introduced in 2006. A person
may bring only the following parts of a dead cervid into Maryland from an area
indicated as positive for CWD in free-ranging or captive cervids: (1) meat with
no part of the spinal column or head attached; (2) meat without backbone; (3)
cleaned hide with no head attached; (4) skull plate cleaned of all meat and
brain tissue; (5) antlers with no meat or soft tissue attached; (6) upper canine
teeth, also known as buglers, whistlers, or ivories; and (7) finished taxidermy
mount or tanned hide.
Any person who imports
or possesses a cervid carcass or part of a cervid that was tested for CWD in
another state or province and is notified that the cervid tested positive, must
report the test results to Maryland DNR within 24 hours of notification.
Due to expanding sika
deer populations into wetland landscapes, Caroline and Talbot counties were
opened to sika deer hunting in 2006.
2006-07 Deer Harvest
The 2006-07 deer hunting seasons provided 900,000 days of outdoor recreation for
thousands of Marylanders. Friends and families of hunters prepared venison
dinners from recipes enjoyed by many generations. During 2006, Maryland deer
hunters donated over 61 tons of venison to the needy through the nonprofit
organization Farmers and Hunters Feeding the Hungry.
Maryland's total deer
harvest for 2006-07 was 91,930 (Table 1),
which represents a 2% decrease from the 94,052 deer taken in 2005-06 (Figure 1).
Antlered bucks numbered 33,114 and antlerless deer (48,005 does and 10,811
button bucks) totaled 58,816 (Figure 2).
Compared to 2005-06, the harvest of antlered bucks remained stable (+.8%) and
the harvest of antlerless deer dropped by 4%.
Bow Season
Maryland's bow season opens in mid-September and closes at the end of January.
In 2006, license sales indicated that about 50,600 residents and 7,100
nonresidents purchased bow stamps that are required to bow hunt for deer. Each
Maryland bowhunter hunts deer for about 13 days. Typically, about 35 % of
archery hunters take 1 deer or more each year.
In 2006-07:
-
Bowhunters took
21,991 deer, including 8,631 (39%) antlered bucks and 13,360 (61%)
antlerless deer (11,498 does and 1,862 button bucks) (Table 1).
-
The antlered bow
harvest increased by 2.4% and the antlerless bow harvest climbed by 3.1%
over the previous year.
-
Crossbow hunters
took 306 antlered deer and 751 antlerless deer during the crossbow season
(Table 2).
-
Eighty-three percent
of the archery harvest came from private lands.
-
Bowhunters took 317
deer (147 antlered, 170 antlerless) on Sundays open to bowhunting on private
land across 14 counties (Table 3).
-
Bowhunters bagged 43
deer (24 antlered, 19 antlerless) during the 5 bow hunting Sundays in
Dorchester County.
Firearm Season
About 60,000 firearm hunters averaged 5.2 days hunting during the firearm
season. Approximately, 45% of firearm hunters bag at least 1 deer each year.
In 2006-07:
-
The firearm harvest
totaled 49,805 compared to 51,826 in 2005-06, a drop of 4% (Table 1).
-
The number of
antlered deer taken was 17,891 (36%) and 31,914 antlerless deer (64%) were
harvested.
-
The harvest of
antlered bucks decreased slightly by less than 2% (1.8%) and the antlerless
harvest (25,456 does and 6,458 button bucks) dipped by 5%.
-
Eighty-six percent
of the firearm harvest comes during the 2-week firearm season (Table 4).
-
Firearm hunters took
54% of all deer harvested in Maryland compared to 55% last season (Figure 1).
-
Eighty-seven percent
of the firearm harvest was taken from private property.
-
Firearm hunters
bagged 2,517 deer (1,046 antlered, 1,471 antlerless) on Sunday, November 26,
2006 across private lands in 14 counties (Table 3).
-
The 2-day either sex
hunts for Region B were held on January 5 and 6, 2007 (Table 5).
Hunters took 2,623 deer during this late season. Over 78% of this harvest
was antlerless deer.
-
Included within the
total firearm harvest are 1,797 deer (1,030 antlered, 767 antlerless) taken
in Maryland's Junior Deer Hunt (Table 6).
The 1-day Junior Deer Hunt requires an unarmed licensed adult over 21 years
of age to accompany each young hunter. This provides an opportunity for an
elder's instruction in safety, hunting techniques, ethics, appreciation of
the outdoors, and passing on of the hunting tradition.
Muzzleloader Season
In 2006-07, the statewide, either sex muzzleloader season included 3 days in
October (October 19 - 21) and 2 weeks during late December (December 16 - 30).
Region B conducted a 6-day antlerless only muzzleloader season (October 23 -
28). This provided for additional deer population management through antlerless
deer harvest.
Resident hunters
purchased 62,200 muzzleloader stamps and nonresident hunters bought 7,800
muzzleloader stamps. The stamps are required to hunt deer with a muzzleloader
or to hunt deer with a bow during the muzzleloader season. Maryland
muzzleloader hunters pursue deer for about 2.7 days each during the October
season and for about 3.5 days in the late 2-week season. In any given year,
about 35% of blackpowder hunters harvest 1 or more deer.
In 2006-07:
-
Muzzleloader hunters
took 88% of the muzzleloader deer harvest on private lands.
-
The muzzleloader
harvest totaled to 20,134 in 2006-07 (Table 1).
-
The total
muzzleloader bag consisted of 6,592 (33%) antlered deer and 13,542 (67%)
antlerless deer (11,051 does and 2,491 button bucks).
-
Sixty-six percent of
the deer taken by muzzleloader hunters were bagged during the October
hunts.
-
Overall, the 2006-07
muzzleloader antlered harvest increased by 6.4%, while the antlerless
harvest declined by 7.6 % compared to the 2005-06 season.
-
During both early
2006-07 October seasons, 4,807 antlered deer and 8,383 antlerless deer were
taken (Table 7).
-
The 6-day
antlerless-only Muzzleloader Season accounted for 3,065 antlerless deer,
down 23% from the previous year.
-
The 2-week late
season harvest consisted of 1,777 antlered deer and 5,147 antlerless deer
(Table 8).
Maryland DNR Deer Plan
DNR’s Deer Project will be revising the 10-Year White-tailed Deer Management
Plan during 2007. The Deer Plan guides all phases of deer management including
proposed deer hunting regulations for the 2008-2009 deer hunting seasons.
Public input plays a major role in this revision process. DNR will announce the
progress of the plan revision process and alert citizens for opportunities for
public input. The Deer Project looks forward to your suggestions and
recommendations.
Impact of Hunting on
Deer Numbers and Ecosystems
Maryland hosted the 30th Annual Meeting of the Southeast Deer Study
Group. The meeting theme was “Deer and Their Influence on Ecosystems”. Three
research presentations documented deer browsing impacts in 4 Maryland public
natural areas. Studies revealed that high deer populations on Assateague Island
National Seashore and on Soldier’s Delight Natural Environmental Area are
negatively affecting endangered plants.
The unmanaged deer herd on
Catoctin National Park has retarded forest regeneration, reduced understory
vegetation cover and biodiversity, and diminished ground nesting birds. In
stark contrast, deer management through Maryland’s deer hunting seasons and bag
limits provide for lower deer numbers and better plant and animal ecological
conditions on the nearby Frederick City Watershed.
Deer Research and Data
Use
The 2006-07 deer season marked the second year that DNR staff collected deer age
and biological data from butcher shops. However, the data collection protocol
was modified in 2006-07 to increase the accuracy of the sample. Instead of
collecting data during the 2-week firearm season, as was done in the past, DNR
staff and volunteers collected half of their samples during early muzzleloader
season and half during the 2-week firearm season. Splitting the sample gives a
better estimate of the herd age distribution since nearly half of the yearly
harvest now occurs before the 2-week firearm season. Preliminary results
suggest that the early-season harvest (bow and early muzzleloader) contains a
higher percentage of yearling bucks than does the firearms season.
In all, 4,771 deer were
examined across the state during the 2 seasons in 2006-07. Deer examined at
butcher shops were sexed, aged, and antler measurements were recorded for
bucks. Deer were also checked for evidence of illness or disease. The yearly
sample of hunter-killed deer provides valuable information that is used to
estimate deer population numbers and to detect any changes in deer herd
reproductive potential. It is also used to monitor the overall health of deer
and the effects of season and bag limits changes that are made to better manage
deer populations.
Staff and volunteers
determine the age of each deer by the wear and replacement of its teeth. As
young deer get older, their milk teeth are replaced with permanent teeth. As
adult deer age, their permanent teeth begin to wear down. This enables
biologists to reliably categorize deer as fawns (less than 1 year old),
yearlings (approximately 1.5 years old) or adults (2 years and older). The
proportion of deer in each age class and their gender are then used in
reconstruction models to develop and follow trends in the state's deer
population.
Measurements of antler beam
circumferences of yearling male deer that are brought to butcher shops are used
as indicators of the reproductive potential and health of the deer herd.
Yearling males in good habitat with moderate deer numbers will weigh more and
have larger antler beam diameters than those in higher populations or poorer
habitat. Abundant food and modest competition translates into more energy
available for antler and body growth. This is most evident in the yearling age
class. Trends in these measurements can indicate deer herd over-population and
habitat degradation. Overall, Maryland's long-term data for these indicators
show healthy, productive deer populations across the state
Table 9.
Sampled deer are also
examined for evidence of hemorrhagic disease; a viral disease spread by biting
midges. Hemorrhagic disease, or "Blue-tongue", commonly appears in late summer
and early fall. Deer that have survived hemorrhagic disease and are harvested
will exhibit hooves with sloughing or peeling tissue. These deer are still
suitable for human consumption. Hemorrhagic disease (HD) occurs yearly in
Maryland, although it varies in intensity. The results of this statewide
examination are reported to the Southeastern Cooperative Wildlife Disease Study
(SCWDS) in Athens, Georgia as part of a nationwide survey. This HD study is one
of the oldest and most complete nationwide wildlife disease investigations in
the country.
CWD Research
Chronic Wasting Disease (CWD) is a disease of the central nervous system that
causes death in cervids. CWD has historically been a disease of the West,
although it is now east of the Mississippi River in Wisconsin, Illinois, New
York and West Virginia. Since 2002, over 3,500 samples have been collected from
Maryland deer and tested for CWD. In 2006, 993 deer were tested for CWD.
Testing in Maryland is a precautionary measure and CWD has not been found in
Maryland.
West Virginia detected CWD
in free-ranging deer during 2005 in Hampshire County, approximately 11 miles
south of the Maryland-West Virginia border of Allegany County. To date, West
Virginia DNR has found 13 deer with the disease. In response to their
discovery, Maryland’s Deer Project increased CWD sampling rates in Allegany
County and collected samples from hunter-killed deer, road kill deer, and deer
taken under Deer Management Permits. A total of 120 samples were collected in
Allegany County in 2006 and none indicated CWD.
Bowhunter Survey
Beginning with the 2002-03 hunting season, DNR conducted the first Bowhunter
Survey to gather observational data about furbearers, deer and other species.
Deer bowhunters recorded the number of animals observed during each hunt. Each
year, a random sample of 10,000 to 20,000 bowhunters are sent a survey and asked
to participate. If you are a bowhunter and don't receive a survey but would
like to participate, contact Robert Colona (410-221-8838, Ext 101) or download
the survey from the DNR Website. The complete results for these surveys
pertaining to deer can be found on the DNR website or by contacting Brian Eyler
(301-842-0332).
In the 2004-05 survey,
Maryland's bowhunters recorded the following statewide information regarding
deer:
-
Statewide
White-tailed Deer Sex Ratios- 1 adult buck per 2.9 adult does. The
Appalachian Plateau Region had the highest sex ratio with 1 adult buck per 5
does and the Western Coastal Region contained the lowest sex ratio of 1
adult buck per 2.3 adult does.
-
Statewide
White-tailed Deer Reproductive Rate- .52 fawns per each adult doe. The most
productive section of the state was the Eastern Coastal Region (.63) and the
least productive section was the Piedmont Region (.42).
Cooperative Deer
Management Between DNR and Maryland’s Counties
Since 1994, DNR has promoted deer management cooperative relationships with
Maryland counties. Montgomery County and Howard County both developed their own
deer management units manned by professional staff. DNR works closely with both
counties regarding the evolution of countywide deer management efforts. Both
counties have implemented nonlethal and lethal deer management programs while
maintaining public support and DNR cooperative advice and guidance. DNR staff
participates in county deer management workshops, reviews and advises on county
deer management plans and issues appropriate state permits for deer management
activities.
In June 2006, Montgomery
County issued a press release titled “Deer Overpopulation Reduced in Montgomery
County”. The press release stated- “Implementation of long-term, effective deer
management strategies is beginning to reduce the overpopulation of deer and
their negative impacts on farm crops, landscaping and deer related collisions in
Montgomery County . . . . “.
Phil Norman, Howard
County Deer Biologist, indicates that Howard County residents support sound
scientific deer management practices implemented across the county. Phil
observes that only a small group of folks still have reservations regarding deer
management techniques.
DNR encourages other
counties to follow the lead of Montgomery and Howard counties to develop a
cooperative deer management relationship with the Deer Project. Interested
county staff should contact George Timko, Maryland DNR Suburban/Urban Deer
Biologist, at 301-948-8243.
Suburban Deer
Management
Deer management in suburban areas ranks as one of the most difficult challenges
facing wildlife agencies throughout the country. Maryland’s Deer Project is
charged with managing deer across the state's varied landscape for a diverse
public with different opinions on deer management issues. This includes the
large suburban corridor in the midsection of the state.
Maryland is developing
rapidly with its increasing human population. Conversion of forested and
agricultural lands into housing developments improves habitat conditions for
deer. Developed areas experience improved deer survival and population
increases. More deer lead to a greater number of negative interactions with
suburban residents, decreasing their tolerance of deer.
Safety concerns and
social considerations in urban areas often prevent the use of many lethal deer
population control measures. Non-lethal control measures, most often used in
developed areas, can help reduce deer problems but they do not eliminate them.
They also do not address the troubles that result from high deer numbers.
Increased deer-vehicle collisions, damage to ornamental plants and gardens, and
damage to natural habitat are some problems that have resulted from this
hands-off style of deer management.
Nonlethal methods can
help reduce some of the damage that deer cause and serve to increase public
tolerance of deer. When public tolerance levels have been surpassed, lethal
methods are often considered. Certain lethal methods can be applied to decrease
the numbers of deer in suburban areas and reduce deer problems.
Effective Suburban
Deer Management
Some deer management techniques are more effective than others at resolving
deer-human conflicts. No single method can completely resolve all deer
problems. Some are applicable only in certain situations. Often, a combination
of non-lethal and lethal techniques is applied to help resolve deer problems,
particularly in suburban areas. The Deer Project will continue to evaluate new
techniques for their effectiveness and suggest proven methods to help reduce
deer-human conflicts.
Deer Management
Information
A section of the DNR website is devoted to public education on deer and deer
management options. Information on nonlethal and lethal methods is provided at
www.dnr.state.md.us/wildlife/ddmtintro.asp. Further information and
assistance can be obtained from the Urban Deer Biologist at Seneca Wildlife
Office, 11960 Clopper Rd., Gaithersburg, MD 20878, 301-948-8243.
Public Property Deer
Management
DNR provides assistance to local governments, communities, and publicly owned
properties that choose to address deer population issues. Public entities that
desire to conduct hunts outside of the regional deer hunting season framework
may do so with prior approval of DNR. Managed hunts are used to help control
deer populations under special conditions on properties where stricter control
of hunters is required. This allows each facility to manage deer hunting to
complement their mission. Military bases and agricultural research facilities,
as well as state, county, and municipal parks have developed deer hunting
programs in conjunction with DNR.
To improve opportunities
for the public to qualify for managed hunts, the Urban Deer Biologist guides the
statewide Shooter Qualification Card program. This program provides public
access to shooting ranges where hunters can become certified at the standards
required to apply for managed hunts held across the state. Total deer taken on
Maryland public lands during the 2006-07 hunting seasons are found in Appendix
1.
Deer Population
Maryland's deer population prior to the 2006-07 hunting season was estimated at
234,000 deer, a decline of about 13% over the 2005-06 estimate of 269,000.
Trends in deer abundance are commonly monitored using harvest estimates and age
structure of the deer herd. These methods work well in areas where hunters have
access to most of the land but are much less reliable for urban/suburban deer
populations, where hunting occurs sporadically.
Liberal antlerless
regulations have slowed or halted deer population growth in many areas outside
the Washington D.C. to Baltimore suburban corridor. In some rural counties, the
deer population has begun to decline. DNR is currently investigating additional
ways to control deer in the suburban corridor where hunting is inhibited by lack
of access to land.
Non-Hunting Mortality
Factors that cause mortality in deer, other than hunting, include disease, young
fawn predation by bears and coyotes, collisions with vehicles, and harvest using
Deer Management Permits. Data concerning deer killed by vehicles (Table 10)
is reported to the DNR by a broad spectrum of agencies (county police, state
police, sheriff deputies, city police, park rangers, county roads and state
roads staff, etc).
Because of its many and
varied sources, this data is used primarily to support harvest and deer damage
trends. DNR is conducting outreach efforts with the State Highway
Administration and each county roads division to increase the accuracy of
reporting deer killed by vehicles. Due to better reporting of deer-vehicle
kills, a dramatic increase was noted from 2005 to 2006.
One major insurance
company estimates total deer vehicle collisions for each state. It is based on
the firm’s share of the insurance business for each state and the number of
accidents reported by their clients. The insurance industry’s estimate of deer
vehicle collisions in Maryland is as follows: 2002-03 - 26,169; 2003-04 -
21,968; 2004-05 - 22,820; 2005-06 - 27,925.
When deer are causing
damage to commercial crops, farmers can obtain a Deer Management Permit (DMP)
from DNR. DMPs allow farmers to harvest antlerless deer on their property
outside of the regular state hunting seasons and bag limits. In 2006, a total
of 4,752 deer were taken on DMPs compared to 7,178 deer in 2005 (Table 11),
a drop of one third. This is the second consecutive year that a major decline
was observed in DMP harvested deer. Apparently, the continued decline is due to
agro-businesses taking advantage of the more liberal bag limits in Deer
Management Region B and declining and stable deer numbers in rural portions of
the state.
In recent years, hunters
have become increasingly concerned about coyote and bear predation on deer in
Western Maryland. Coyotes have increased in number in Washington, Allegany, and
Garrett counties over the last 5 years. Very young fawns in the spring can be a
food source for them. Likewise, the black bear population is expanding and
population numbers are at record highs for recent times. Studies in other
states indicate that bears have been shown to be equally effective or more
effective at predating fawns than coyotes.
Currently, reproductive
data that the Deer Project collects does not indicate coyotes or bears are
having a significant impact on the western Maryland’s deer population. The
recent decline in Western Maryland deer numbers can be largely attributed to the
relatively high percentage of antlerless deer being taken during the hunting
season. While there's no doubt that coyotes and bears are predating fawns,
Maryland’s long-term deer data along with research and experience from nearby
states indicate that their effect is minimal. The vast majority of white-tailed
deer give birth to fawns within a 2-4 week period in May and June, which
overwhelms predators like coyotes and bears. During that time, there are far
more fawns on the ground than can be consumed by predators, thus ensuring that
an adequate number will survive to reproduce in coming years.
The Deer Project will
continue to monitor the coyote and bear situation in Maryland and develop
alternative management plans if the need arises.
Trophy Deer Contest
Each year the Maryland Bowhunters Society and DNR cosponsor the
Maryland Trophy
Deer Contest. This contest recognizes
hunters who have harvested trophy bucks and promotes quality Maryland deer
through wise management. The goal of quality deer management is to produce deer
numbers that are in balance with the available habitat and have deer that reach
maximum size and are in good health.
DNR's deer management
practices continue to improve the quality of Maryland's deer herd. By
encouraging antlerless deer harvest and restraining antlered buck harvest,
populations will reach appropriate levels while the potential for mature
antlered buck survival improves.
The 2006 Trophy Deer
Contest for bucks taken in the 2004-05 hunting season was held during the
Frederick Sports Expo at the Frederick Fairgrounds.
