Efforts to introduce
wild turkeys into Washington have been made since the early 1900s.
Since 1960, when the first wild-trapped turkeys were introduced into
the state from Arizona, New Mexico, and Wyoming, turkeys have maintained
naturally reproducing populations in much of the forested portion
of eastern and southwestern Washington. Currently, three sub-species
of wild turkey (Merriam’s, Rio Grande, and eastern) can be found
in Washington with some Merriams/Rio Grande crosses likely in some
areas of eastern Washington. As
the result of an aggressive introduction program that began in the
mid-1980’s, Washington’s wild turkey populations have
experienced substantial increases in density and distribution. Recreational
interest in the wild turkey has increased along with the populations.
The number of turkey hunters in Washington has increased from 689
in 1984 to over 15,000 in 2004. Wild turkeys are also popular with
bird watchers and photographers who also take advantage of the turkey
calling experience.
Wild turkeys are adaptable to a broad range of habitats and weather
conditions. In Washington, management efforts have focused on matching
sub-species to the habitat types that most closely approximate that
of their native range. Available food resources, nesting and roosting
habitat, and precipitation regimen are some of the factors that
have been considered through time.
Wild turkeys
eat many different kinds of plants, seeds and fruits, and invertebrates
(insects, spiders, snails), usually focusing their diets on the
food items that are most available. In general, the diet of an adult
turkey is made up of 75% plants and 25% insects while the diet of
a poult ranges from 75% to 90% insect matter. During the winter,
turkeys in eastern Washington gather into large flocks, sometimes
of 100 or more birds, and are commonly found around a source of
artificial feed like oat hay or other grain.
Throughout their
range, wild turkeys are vulnerable to various diseases and parasites.
This is complicated by the fact that they are susceptible to many
of the same diseases that domestic chickens and turkeys carry. In
efforts to keep these avian diseases from impacting both wild and
domestic stock, the Washington Department of Fish and Wildlife (WDFW)
tested all of the turkeys that were imported from other states prior
to release. In addition, many of the turkeys that have been trapped
within the state have also been tested. To date, there have been
no positive results reported for any of the birds tested.
The number of
turkey nuisance complaints has increased over the past 10 years,
especially in parts of northeastern Washington where the populations
have expanded the most. WDFW response to these complaints has ranged
from telephone conversations with landowners to trapping offending
birds. In very few situations, lethal removal of a specific number
of birds has been authorized.
The first turkey
hunting season was conducted in the fall of 1965 (one and a half
days in northeastern Washington). The length of the season increased
over time and in 1970, the first male only spring hunting season
was conducted. In the late 1980’s, the spring season was three
weeks long and a one-week fall either sex season was also held.
In 1994, the current 30 day spring season was established and the
bag limit was increased to three. In addition, a special youth hunt
was established in 2003 which contributed to the more than 63,000
days hunters spent afield hunting turkeys that year.
Currently, WDFW
relies on turkey hunter harvest reports to provide an index to turkey
population status. In an effort to provide a harvest-independent
measure of population growth, WDFW is proposing to enlist the help
of volunteers to implement a wintertime road transect count. WDFW
is not recommending a harvest-independent survey in western Washington
because the eastern sub-species does not typically gather in large
flocks and it is difficult to obtain adequate turkey counts in the
dense forest habitat with low turkey densities.
Establishing
and managing self-sustaining populations of wild turkeys in the
most suitable habitats continues to be a primary objective of the
wild turkey management program. Since a vast majority of the most
suitable habitats currently support turkeys, very few areas are
designated as potential introduction areas. Also, there are no plans
to release additional birds in areas where significant introduction
plans were recently implemented.
Damage and nuisance
issues will continue to arise, however, trapping will not be a primary
mitigation response. A nuisance response “toolbox” that
focuses on alternative actions has been developed. When alternative
methods fail to address the nuisance problem, trapping is still
an option. Turkeys trapped in response to nuisance and damage complaints
will be released within the Primary Wild Turkey Management Area
in or adjacent to currently occupied areas. In addition, trapped
turkeys may also be released in the potential introduction area
if the sub-species is identified as the most appropriate for that
area.
Since wild turkeys
are not native to Washington, questions arise about the impact that
wild turkeys might have on native wildlife and plants. There have
been many wild turkey studies completed across the United States
(in both native and introduced range), and none of these studies
have indicated that wild turkeys have negative population-level
impacts on plants, animals, or other birds.
Before turkeys
can be released in the Potential Introduction Area, the proposal
must be evaluated by local, regional and program staff. The evaluation
will include, at a minimum, examination of current and potential
nuisance and damage issues, impacts to existing management actions,
impacts to the long-term survival of state and federally listed
species (e.g., endangered and threatened) as well as candidate and
sensitive species, and recreational and economic benefits. Measures
to mitigate potential negative impacts, if they exist, will be identified.
If impacts cannot be mitigated or no mitigation measures can be
found, turkeys will not be released on that site.
Additional biological
and management information is needed to help manage turkeys in the
state of Washington. Specifically, WDFW is interested in conducting
or helping conduct investigations to address the issues of inter-specific
competition and wild turkey nutrition throughout the state, and
habitat utilization and limiting factors analysis in western Washington.
Conducting habitat
improvements for the wild turkey is going to receive greater emphasis
in the future of the wild turkey management program. Habitat improvements
can be done in cooperation with other state or federal agencies
as well as non-governmental organizations (e.g., the National Wild
Turkey Federation). In many cases, habitat improvements made for
the wild turkey will also improve habitat conditions for other species
in the area. Habitat projects that provide these multiple values
will be a priority.
Providing quality
hunting opportunities will continue to be a priority for the turkey
management program. Information gathered from surveys of hunters
has identified hunter access to private property as one of the most
important issues to Washington hunters. As a piece of an overall
hunter access program, efforts will be made to improve access for
turkey hunters in much of the state. In addition, WDFW will continue
to collect the best harvest information available through the current
mandatory reporting system. This information is critical to providing
the appropriate level of recreational opportunity.
No program is
complete without a concerted effort provide the public with information
about the wild turkey program in general as well as specific information
about avoiding negative interactions, ongoing turkey management
activities, and the variety of recreational opportunities available.
There may be opportunities to partner with various organizations
and agencies to develop and distribute many of these materials. |
