Volunteers take to wetlands for annual frog and wetland counts

MADISON – While most wildlife surveys depend upon keen eyesight to identify animals, it’s ears -- not eyes -- that are the most important tools as dozens of volunteers fan out across Wisconsin’s wetlands this April for the annual survey of frogs and toads, the nation’s oldest of its kind.

The counters rely on hearing, not seeing, the frogs to get a sense of how these nocturnal creatures are faring, says Bob Hay, an amphibian specialist with the Department of Natural Resources. “It’s a lot easier to hear frogs than see them.”

DNR coordinates the Wisconsin Frog and Toad Survey, which has provided important long-term data and trends on amphibian species and their habitats since 1984. The survey, carried out completely by volunteers, many of them DNR biologists and researchers, is the longest running amphibian monitoring program in the country.

“The survey is designed to provide general trend data for Wisconsin frogs, not a head count,” Hay says. “Volunteers don’t record individual frog numbers.”

Every year, volunteers drive a route with 10 sites between April 8 and April 30 to listen for frog calls. They count along the same routes during separate periods in late May or early June, and again in early July. The survey current involves about 1,000 wetlands a year.

The presence or absence of each frog species at a particular site is based on the breeding calls of male frogs, with the relative number of calling individuals ranking the abundance of each species, according to Mike Mossman, a DNR researcher involved with the survey since its inception.

While it’s difficult to tell exactly how many frogs are calling, a discerning counter can tell whether they’re hearing a few individuals, a handful, or a full chorus, he says.

The counters listen to the species that are calling for five minutes at each site. They record data by a call index: 1, when individual calls do not overlap; 2, when the calls of individual cans be distinguished but there is some overlapping of calls, and 3, when there’s a full chorus and the calls are constant, continuous and overlapping, Mossman says.

Wisconsin has 12 frog species -- which includes one toad species, the common American toad – and true frogs, like the northern leopard frog, and tree frogs, like the spring peeper. Tree frogs generally spend more time on land and often move greater distances from water or wetlands than true frogs, with the exception of the leopard frog, which regularly forages long distances from water. Different species breed during different times in different kinds of wetlands, thus the need for the three different survey periods, Hay says.

All of the frogs and toads deposit their eggs in water. Frog species breeding in April tend to be the wood frog, chorus frog, spring peeper, leopard frog and pickerel frog. The wetland habitats these species use are often the temporary, or “ephemeral” ponds that have been created by snowmelt and spring rains, Mossman says. These temporary wetlands are particularly important to the fate of these species because these wetlands generally lack the fish that can prey upon frog eggs and larvae.

“The changes the frog and toad survey show from year-to-year may not be significant, but long-term ones may be,” Mossman says. “Not only do these trends reveal what’s happening with a particular frog species, but with the larger environment.”

Frogs and toads are sensitive to environmental conditions like habitat quality and chemical contaminants, and as such are sentinel species, letting humans know of problems in the environment. They are an important strand in the ecological web that links wetlands and uplands, and their breeding choruses serve as sentinels of environmental health, Mossman says.

“A full chorus of frogs is one sign of well-being not only for the frogs, but for the systems on which they, other wildlife, and people depend. Conversely, when a pond goes silent, it’s a warning,” he says.

Data over the course of the survey show most Wisconsin frog species are holding up pretty well, Hay says. “Our frogs in general are looking pretty good,” Hay says. “We’ve got a number that have increased, a number that are stable, and two with significant declines.”

Blanchard’s cricket frog experienced significant declines from the early 1960s to the late 1980s, but the species appears to have since stabilized. While the causes of the decline haven’t been absolutely determined, it appears that a series of harsh winters affected the frog, which occurs in Wisconsin at the northern fringe of its range, Hay says.

Northern leopard frog populations are also declining, and regularly show malformations. This species is particularly sensitive to chemical contaminants, and the declines and malformations likely reflect changes in water quality, Hay says.

Efforts to monitor frogs and amphibians, and many other nongame, rare and endangered species are funded in part by the Endangered Resources Fund, through which Wisconsin residents can donate to through the checkoff on state income tax forms.

“Amphibians of Wisconsin,” a 44-page guidebook with color photos of Wisconsin frog, toad and salamander species and information about their habits and habitats, is available for purchase from DNR’s Endangered Resources Bureau for $4; or a set of three books on Wisconsin reptiles is available for $10. Information on ordering publications is on the DNR Web site or is available by calling (608) 266-7012.

Hatcheries provide shore fishing opportunities on Lake Michigan

MISHICOT, Wis. -- Wisconsin’s experimental program to boost shore fishing opportunities along Lake Michigan seems to be working: anglers fishing from piers or from the shore are catching the fish and the fish are even bigger than expected, state fisheries officials say.

The Department of Natural Resources started annual stocking of the Arlee strain of rainbow trout in Kenosha, Milwaukee, Sheboygan, Manitowoc, Algoma and Sister Bay harbors in 2001. Stocking of the Kamloops strain started in 2003 at the same harbors.

“The main goal of this project is to find a strain of fish that stays close to shore so shore and pier anglers have the opportunity to catch them,” says Steve Hogler, the Michicot-based DNR fisheries biologist who’s coordinating the program. “Results from our creel survey indicate that most of these fish have been caught by the group of anglers we’re targeting and their growth seems to be even better than predicted.”

This spring, stocking of 60,000 Kamloops started in late March and ended last week; stocking of 60,000 Arlee started last week and will continue for the next few weeks.

Rainbow trout are the same species as steelhead, and the three steelhead strains DNR has stocked since the 1980s (Skamania, Chambers Creek and Ganaraska) continue to wander away from shore so that the vast majority -- 94 percent of all steelhead caught -- continue to be reeled in by anglers in boats. But boaters are capturing less than half of that proportion of the Arlee and Kamloops strain rainbows stocked, so that most of these fish are being caught by anglers from shores or piers, Hogler estimates.

And the Arlee are bigger than expected at this time: fish upwards of 10 pounds, instead of the 5 to 7 pounds expected, Hogler says. In fact, an angler fishing from a pier landed a 33-inch, 16.5-pound Arlee that won the steelhead category in the 2005 Port Washington Derby, he says. Anglers also reported in 2005 that they were catching fish in the 12-pound range.

DNR launched the experimental stocking program with a goal of stocking 10,000 rainbow of each the Arlee and Kamloops strains at each port to help directly compare the two strains. The Arlee eggs are collected and fertilized at the Ennis National Fish Hatchery in Montana before being transferred to Kettle Moraine Springs State Fish Hatchery in Adell, where they’re hatched and fed for three months before being transferred to Lakewood State Fish Hatchery for a few more months before stocking, according to Jesse Landwehr, Lakewood State Trout Hatchery assistant hatchery foreman

More than 240,000 Arlee rainbow have been stocked in the six harbors since 2001, with another 60,000 slated to go out this spring and stockings also planned in 2007 and 2008.

The Kamloops strain come from Minnesota’s Department of Natural Resources and are raised at the Kettle Moraine Springs State Fish Hatchery. More than 170,000 Kamloops strain fish have been stocked since 2003, and 60,000 are slated to go out this spring and in the spring of 2007.

Hogler says DNR will continue to evaluate the performance of the two strains of fish for several years; Kamloops are longer-lived than Arlees, so the department needs to wait a few years to see how well the older fish return to the shoreline.

“People seem pretty happy with these strains. Anglers are catching the fish, and they’re especially pleased with the Arlees, which get to be pretty chunky and are not long and lean like most steelhead,” Hogler says. “The information we collect in the next few years will help us learn whether the stocking is worth continuing.”

The experimental stocking program is being funded by revenues from sales of the Great Lakes Trout and Salmon Stamps anglers must buy to fish trout and salmon in Lake Michigan and Lake Superior.

Walleye bag limits revised for ceded territory lakes

MADISON -- The daily walleye bag limits have been revised on 274 lakes in the Wisconsin Ceded Territory in response to harvest declarations made by six bands of Chippewa in Wisconsin, the state Department of Natural Resources has announced. These bag limits are effective between May 6, 2006 and March 4, 2007, inclusive.

There will be a three walleye bag limit on 133 lakes, a two-fish daily bag limit on 139 lakes, and two lakes will have a daily bag limit of one walleye. Spirit and Virgin Lakes (Oneida Co.) will have a 45-inch minimum for muskellunge.

The revised bag limits are available in portable document format on the DNR Web site and are being published as an insert to the Guide to Wisconsin Hook and Line Fishing Regulations 2006-2007. Lakes not listed are subject to the regulations printed in the regulations pamphlet. The statewide daily bag limit for walleyes on many Wisconsin lakes remains at five fish per day, but anglers should check the regulations for special size and bag limits that are in effect on specific waters.

Lakes declared by the Lac du Flambeau Band have a daily bag limit of three walleye for sport anglers. In 1997, the DNR and the Lac du Flambeau Band signed an agreement that gave the Band authority to sell tribal licenses honored statewide in return for making declarations at a level that allows a three walleye per day recreational angler bag limit.

As part of a 1983 federal Appellate Court decision affirming Chippewa off-reservation hunting, fishing, and gathering rights, the six bands of Wisconsin Chippewa set annual harvest quotas for off-reservation lakes in the Wisconsin Ceded Territory. As part of court agreements, to assure the combined tribal and recreational angler harvest does not exceed the ability of walleye to sustain its population in any lake, the Department of Natural Resources must revise bag limits for recreational hook and line anglers in lakes declared for harvest by the Chippewa bands. The state is entering its 21st year of the joint tribal and recreational fishery.

For background information on Chippewa treaty rights, a description of the management and monitoring system used to ensure the viability of fisheries in the Ceded Territory, and to see data collected as part of that monitoring system, including walleye population estimates and creel survey summaries for all gamefish, check out the DNR Bureau of Fisheries Management Internet pages regarding the joint tribal and recreational fishery in the Wisconsin Ceded Territory.

Governor Doyle signs wildlife violator compact

MADISON – Gov. Jim Doyle signed into law the Wildlife Violator Compact in an April 8 ceremony held at the Wisconsin Wildlife Federation’s annual meeting in Tomah.

The Wildlife Violator Compact allows the Wisconsin Department of Natural Resources to join 19 other states in the International Wildlife Violator Compact. Under the compact, a suspension or revocation of hunting, fishing or trapping privileges in any of the member states will be honored in all member states.

“This bill clearly communicates that poachers and violators of fish and game laws are not welcome in Wisconsin,” said Governor Doyle. “Wisconsin is sending a strong message about our conservation ethic and the values these resources represent in our lives and our communities.”

“This legislation would not have been possible without the support of many state conservation organizations,” said DNR Secretary Scott Hassett. “I’d like to personally thank the Wisconsin Bearhunters Association, the Wisconsin Wildlife Federation, the Wisconsin Conservation Congress and the League of Conservation Voters for their work on this bill.”

The compact is designed to serve as an additional deterrent to violations of wildlife laws in all member states.

“Violators who have had their hunting, fishing or trapping privileges revoked or suspended will no longer be able to escape the consequences of their actions by engaging in those activities in a neighboring member state,” said DNR Chief Conservation Warden, Randy Stark. “Their court-imposed revocation will follow them and will be in force in all of the compact states.”

Costs associated with the legislation would be offset by a $5 surcharge that would be added to the penalty imposed on each person convicted of a fish or wildlife violation in Wisconsin, explained Stark.

“The legislative sponsors and conservation organizations who supported this bill were innovative in finding a way to pay for it,” said Hassett, “they set it up so the violators foot the bill. This way, law abiding sportsmen and women won’t have to pay for administering the compact.”

The following states are currently compact members: Arizona, California, Colorado, Georgia, Idaho, Indiana, Iowa, Maryland, Minnesota, Missouri, Montana, Nevada, New Mexico, North Dakota, South Dakota, Oregon, Utah, Washington and Wyoming

Dam operating agreement to allow for more natural water flows

Game fish and dozens of rare fish and mussel species to benefit

ST. CROIX FALLS, Wis. – Water flows on the St. Croix River below St. Croix Falls will mimic more natural flows under an agreement to be signed April 13 by the Department of Natural Resources and Xcel Energy. The agreement will benefit game fish and dozens of threatened and endangered fish and mussel species.

The Memorandum of Agreement (MOU), is the culmination of negotiations governing the river flow below the utility’s 1905 era St. Croix Falls hydroelectric dam, according to Terry Margenau, DNR St. Croix Basin team supervisor.

“The MOU approach is a reasonable way to protect public interests and natural resources of national and international significance while maintaining energy production,” he says. The agreement will require a three-year test period to evaluate Xcel Energy’s ability to operate under the agreed-upon conditions.

The St. Croix River has national significance as one of the most diverse riverine ecosystems in the upper Midwestern United States, with at least 68 fish species, 39 mussel species, and 497 aquatic invertebrates including insects. Thirty-nine populations in the St. Croix River are listed as endangered, threatened, or special concern species under the federal Endangered Species Act and the state Endangered Species Acts of Wisconsin and Minnesota. The world’s only confirmed reproducing population of the winged maple leaf mussel inhabits a 12-mile reach of the St. Croix River downstream from the hydroelectric project.

Signing of the agreement is scheduled at Interstate State Park in St. Croix Falls at 1 p.m. April 13 with a tour of the St.Croix Falls Hydroelectric facility to follow.

‘Healthy Forest’ pilot projects topic of informational meetings

MADISON – A pilot program intended to determine the effectiveness of providing free or low-cost forest management services to private non-industrial forest landowners will be the topic of two upcoming informational meetings.

The Wisconsin Healthy Forest Program (WHFP) is conducting three pilot projects funded in part by $61,000 in grants from the Turner Foundation, the Weyerhaeuser Corp and the Federal Forest Legacy program. The projects areas include Liberty Grove Township in Door County, Baraboo Bluffs in Greenfield and Caledonia Townships in Sauk and Columbia counties and the Stora Enso Family Forest program in Portage County.

“The overall objective of the pilot projects is to judge the effectiveness of using local sponsors to assist forest landowners in practicing sustainable forestry on their lands,” said Paul Pingrey, private forestry specialist with the state Department of Natural Resources. “It will provide another avenue for landowners to access professional forestry services.”

The sponsors will work to alert landowners to the benefits and availability of professional forestry services in their area and assist landowners in contracting for forestry services.

“Having a single sponsor working with many landowners in a township will help define what issues are common to neighbors, such as wildlife habitat, water quality, invasive species and endangered and threatened species and help coordinate efforts to address those issues,” Pingrey said.

Each pilot project will be roughly one township in size. The local pilot sponsor will be charged with developing an overall forest plan for the entire project area and then enlisting interested individual landowners into more detailed management plans for their properties – all at no initial cost to the landowner.

“The sponsors will provide a kind of clearing house or subcontractor service to participating landowners,” explains Pingrey. “The sponsors can be a local government or conservation organization, industry or environmental group. They’ll provide the initial assessment free of charge and do the legwork lining up potential foresters, loggers and other services for the landowner to choose from. “Landowners will be responsible for any charges billed by contracted foresters, loggers or other professionals they may hire to further develop or carry out their management plans.”

The meetings on the Healthy Forest Program pilots are scheduled at 6:30 p.m. on:

  • April 18, Baraboo, in Room B-24 of the Sauk County West Square Building (located five blocks south of Hwy. 33 on Hwy. 123 and just west of the courthouse square).
  • April 20, Sister Bay, 6:30 PM at the Liberty Grove Town Hall, 11161 Old Stage Road.

Currently approximately 20 percent of private non-industrial forest owners are enrolled in the state’s Managed Forest Law (MFL) with the rest either having no management plan, a plan drawn up by a private, industrial or government forester or one they’ve written themselves. A management plan takes into consideration the current condition and resource values associated with the land and the owner’s management objectives. MFL enrollment offers a deferred tax incentive but requires the landowner to pay for a detailed management plan and sign a multi-year contract. There would not be any contract involved with the Wisconsin Healthy Forest Program.

“Landowner participation is voluntary with a ‘take it or leave it’ option open to landowners once they see the initial management plan for their property, says Pingrey. “If they choose to implement the plan, the project sponsor will assist the landowner by lending their expertise and experience in dealing with forest contractors.

“A landowner may only sell timber two or at most three times in their lifetime,” says Pingrey. “It’s easy to forget details when things are spaced years or decades apart. New contractors come into and old ones leave the forestry business, so it’s hard to keep current. And, there may be new best management practices available that the landowner is unaware of, which if followed, can minimize impact to soils, surface waters, wildlife and remaining forest stands.”

The Wisconsin Healthy Forest Program is a public-private partnership being coordinated by Wisconsin Family Forests, Inc., Gerry Mich, executive director, 625 E County Road Y Suite 700, Oshkosh, Wisconsin 54901, (920) 424-7888.

Project collaborators include: Wisconsin Family Forests, Wisconsin Woodland Owners Association, DNR-Division of Forestry - Cooperative Development Services, Clark Forestry, Stora Enso, Dovetail Partners, The Nature Conservancy, UW Department of Forest Ecology, Turner Foundation and the Weyerhaeuser Family Foundation.

“If the results from the pilot projects are favorable, DNR might consider offering the WHFP statewide sometime in the future,” Pingrey says.

Transmission line project may result in ‘Incidental Take” of rare turtles

[EDITOR’S NOTE: Wisconsin’s endangered species law (s. 29.604, Wis. Stats.) requires the Department of Natural Resources to notify the public when it proposes to authorize the incidental taking of a state endangered or threatened species.]

MADISON – The construction of a portion of a high-capacity electricity transmission line across northern and central Wisconsin could result in the incidental taking of two rare turtles if they are encountered during construction. The state Department of Natural Resources has received an incidental take authorization request for the project.

As part of the environmental permitting process for the American Transmission Company line from Wausau, Wis. to Duluth, Minn., a screening for rare species determined that a number of locations within the corridor in Wisconsin could potentially contain suitable habitat for the wood and Blanding’s turtles, which are listed as a threatened species under state law. The 345-kilovolt (kV) transmission line will be approximately 220 miles in length, 208 miles of which are located in Wisconsin.

DNR staff and a qualified herpetologist further evaluated the corridor and recommended measures that will avoid most impacts the project will have on the turtles. However, they determined there are nine areas along the corridor where measures could not be implemented to avoid impacts on the turtles, and where “incidental take” may occur.

Under the “incidental taking” law, which was approved by the Wisconsin Legislature in 1997, the Department of Natural Resources can authorize the taking of an endangered or threatened species from a location if that removal will not jeopardize the species' survival or recovery in Wisconsin.

One segment in Sawyer and Rusk Counties, known as the SB spread, is approximately 30 miles long and includes 9 sites where the presence of both turtles is suspected. A second segment in Rusk and Chippewa Counties, known as the BC spread, is approximately 23 miles long and includes one site where the presence of wood turtle is suspected. Project developers will undertake a variety of measures to minimize the potential impact on the turtle, including installing turtle exclusion fencing and conducting turtle removals prior to any construction activity. In addition, the extent of vegetation clearing will be reduced at all locations, low impact clearing methods will be used within suitable habitat, and a qualified herpetologist will be responsible for on-site monitoring during construction. Finally, the land disturbed during construction will be restored to natural vegetation upon project completion. The overall loss of turtles is expected to be very low.

DNR staff have concluded that the proposed project will minimize the impacts to the turtles by adhering to conservation measures; is not likely to jeopardize the continued existence and recovery of the state population of these turtles or the whole plant-animal community of which they are a part; and has benefit to the public health, safety or welfare that justifies the action.

Conservation measures to minimize the adverse effect on the threatened species will be incorporated into the proposed Incidental Take Authorization. Copies of the conservation measures, background information on the turtle, and the jeopardy assessment are available on the Incidental Take page of the DNR Web site or upon request from Andy Galvin, Department of Natural Resources, Bureau of Endangered Resources, 101 South Webster, Madison, WI 53707, (608) 264-8968. Public comments will be taken through May 12, 2006 and should be sent to Mr. Galvin at the above address.

Course to teach proper techniques
in building mountain bike trails

WAUPACA, Wis. – People interested learning the proper techniques for building mountain bike trails that will last a long time, have minimal maintenance, protect the environment from trail damage, and enhance riders’ enjoyment can register for a trail-building course to be offered April 29-30 at Hartman Creek State Park near Waupaca.

A “Trail Care Crew” from the International Mountain Bicycling Association’s (IMBA) will teach proper trail-building techniques while assisting local mountain bikers and other interested individuals in building the first single-track mountain bike trail at Hartman Creek State Park.

The Trail-building School will consist of a half-day of classroom instruction followed by a half day of hands-on trail building. The school begins at 8:30 a.m. on Saturday, April 29. The work will continue Sunday morning, followed by opportunities to ride the new trail. The plan is to start development of the “Bramble Loop,” a 5-mile mountain bike trail within the state park.

There is a $10 registration fee to cover the cost of lunch and a spaghetti dinner at a Waupaca restaurant. Following the dinner on Saturday night will be an evening social and presentation by the Trail Crew. Lunches will be catered to the project site on Saturday.

The Trail Care Crew, consisting of two full-time, professional trail experts, travel North America year-round teaching “sustainable trail building.” The visit is one of 70 stops on the organization’s 2006 schedule. The crew’s visit to Waupaca County is also being sponsored by the Friends of Hartman Creek State Park, and the Wisconsin Off-Road Bicycling Association (WORBA).

The IMBA crews have led more than 1,000 trail projects since the program debuted in 1997. The crew’s trail building schools bring together government officials, public land managers, local mountain bikers, and other to improve mountain biking opportunities.

The trail building techniques they teach are not just limited to bicycle trails, as all user groups can expect to gain valuable knowledge about building better and more sustainable trails.

To register for the Hartman Creek event, e-mail Joseph Warren at <joseph.warren@dnr.state.wi.us> or call (608) 267-7487. Space is limited and pre-registration is required. Participants are responsible for their own overnight accommodations. Camping is available at the park and those interested in camping should note that when registering.
