Venues
The meeting will take place primarily at four locations:

Northwest Inn: This is the conference hotel. It is at the intersection of Williams Avenue (=Highway 270) and 1st Street, about 1.5 miles south of downtown on the south side of town. There will be a shuttle van that will provide transportation between the Inn and the other meeting sites.  

Plains Indians and Pioneers Museum: 2009 Williams Avenue, 1.0 mile north of the Northwest Inn and about 1/2 mile south of the Arts Theater. 

Woodward Arts Theater: Most sessions will take place at the Arts Theater. It's downtown, on Main Street between 9th and 8th Streets, on the north side of the street, and 1.5 miles north of the Northwest Inn. There are many shops and cafés along Main Street in the area around the Arts Theater. Parking is best at the public lot less than one block south of the theater (see "Parking," below). 

Pioneer Room: In the Civic Center, on the east side of 9th Street at corner of Oklahoma Avenue, a little over one block south of the Arts Theater, in easy walking distance. Parking is catty cornered across the street. 

 

Check-in and Registration
Check-in and on-site registration will take place at the Northwest Inn on Monday, 5 November, from noon until 5 pm, then at the Plains Indians and Pioneers Museum from 5 - 9 pm. This will continue Tuesday morning, 6 November, 8 - noon at the Woodward Arts Theatre.

The Morning Field Trips will include the possibility of visiting an active gobbling ground of Lesser Prairie-Chickens near Woodward. The Thursday Field Trip will include visits to Lesser Prairie-Chicken study sites and habitat conservation projects in the Woodward area. Although the Thursday Field Trip is scheduled for all day, it will have an easy break-point at noon, so those wishing to leave then may do so. 

Accommodations
The Woodward area is known for its quail hunting, and the meeting hotel will likely fill up with quail hunters from far and wide, so early registration is important! We have asked for a block of 50 rooms for the conference at the conference hotel (Northwest Inn), but as mentioned in the previous newsletter, if you plan to attend the meeting, please make your reservations as soon as possible. If it turns out that the meeting attendees will need more than 50 rooms, it will be necessary for us to make those reservations early. If you do not make reservations early, primitive campsites will be available at Cooper WMA. 
To make reservations, contact the Northwest Inn (800-727-7606; 580-256-7600; fax 580-254-2274; P.O. Box 1006, Woodward, Oklahoma 73802, USA). Be sure to tell them that you are booking for the Prairie Grouse Technical Council Meeting
Other hotels and Bed-and-Breakfasts in Woodward are listed at www.woodwardok.com/lodging.htm

Transportation
Because Woodward isn't right near the airport, some of you will have transportation needs. For the meeting there will be a small number of vans to bring people from the Oklahoma City and Tulsa airports. If possible, we'd like to get an estimate on how many people will need transportation from and back to these airports. If you think you'll need transportation, even if you aren't sure or don't know what day you might need to travel, please contact Russ Horton (405-202-5901; rhorton@onenet.net). 

There will be a shuttle van that will provide transportation between the Northwest Inn and the other meeting sites within Woodward.  

Parking
Parking for the Woodward Arts Theatre or the Pioneer Room is available along Main Street, but it is perhaps better at the public lot less than one block south of the theater on the west side of 9th Street and Texas Avenue by the Stock Exchange Bank.  This is catty cornered northwest from the Civic Center, which houses from the Pioneer Room. 

Quail Hunting
For those interested in quail hunting while at the meeting, please contact Russ Horton (405-202-5901; rhorton@onenet.net) beforehand for details on licenses, etc. The meeting hotel (Northwest Inn) has a free kennel for those who wish to bring their dogs, but it costs an extra $10 per night for the dog to be quartered in your room. 
For more information about quail hunting seasons, regulations, and how to obtain a license, direct your browser to the Oklahoma Department of Wildlife Conservation's web site at www.wildlifedepartment.com.

MESSAGE FROM THE CHAIR

Call for Agenda Items

If you have a topic of importance you wish placed on the business meeting agenda for discussion, please contact me, 
Russ Horton, at 405-202-5901 or rhorton@onenet.net.

My Fellow Grousers:

Greetings once again from the Great State of Oklahoma. No doubt all of us have been affected immensely by the tragic events on the east coast. May each of us, as we reflect on these events, remember to appreciate and not take for granted the freedoms that we enjoy, and may we also understand that freedom has a great price. May we also look for every opportunity to be a help and encouragement to our fellow man.

As I write this, it is only six short weeks until we are scheduled to gather in Woodward. I trust that all have made the necessary arrangements, and that attendance and participation will ensure a wonderful meeting.

Likely most of you would not have heard, but due to a scheduling conflict, I will not be able to attend this meeting. The state planning committee, however, comprising a number of exceptional individuals, will ensure the success of this meeting. I will continue to be involved in the planning, and certainly encourage you to contact me if you have any questions, comments or concerns.

We have been blessed these last weeks with some beautiful fall-like weather, and much of the state has been getting some much needed rainfall. It looks like the weather for the meeting should be pleasant (not too hot), which will certainly make the outdoor activities more enjoyable. I do have to report that our August roadside quail surveys indicated that quail populations are rather low. The country around Woodward, however, is without question some of the best quail habitat in the U.S., and all are encouraged to spend a few extra days here enjoying the outdoor experience that Oklahoma offers.

I regret that I will not be able to meet with you, and will greatly miss the fellowship and opportunity to learn more about the birds that we love. I wish each of you a safe and enjoyable trip, and pleasant and profitable days.

Regards,
Russ Horton


AUCTION ITEMS NEEDED

As at previous meetings, we plan to have an auction. Funds from the auctions are used to support the meeting (and therefore keep your registration low).

But to have an auction, we need something to sell! We rely on your donated items to fill out our catalog. Could you please donate items for the auction? Items may be small and fun, or go up to whatever you may want to give. Previous auction items have included caps with state or province wildlife department logos; t-shirts; food items (I remember wild rice being popular in Gimli); sets of note cards with wildlife motif; books (if you have duplicate copies this is a great place to get rid of the extras), etc.

Needed Auction Items
Caps Pictures / Paintings
T-shirts Food Items
Books Etc.

If you wish to donate an item for the auction, please bring it with you to the meeting. If it’s something you wish to ship, please contact Russ Horton (405-202-5901; rhorton@onenet.net) for shipping instructions.


STATE REPORTS AND UPDATES

Rangewide Study of Genetic Patterns in Sharp-tailed Grouse

by Karen Mock
Department of Fisheries and Wildlife
Utah State University  

Karen Mock is embarking on a rangewide genetic study of Sharp-tailed Grouse. This project is being performed in conjunction with Michael Schroeder and Ken Warheit in the Wildlife Research Division of the Washington Department of Fisheries and Wildlife. This work is intended to expand on that of Ellsworth et al. (Auk, vol. 111, no. 3, pp. 661-671, 1994) by including a broader geographic range and using very sensitive DNA fingerprinting techniques. The results of this study should help to answer questions about the genetic uniqueness of different subspecies or regions. An understanding of these patterns will provide game managers with the tools to make more informed decisions about translocation strategies and conservation priorities. A large-scale effort to collect wings and other tissues from grouse hunters is underway this fall. Although this seems to be a low grouse production year, these researchers hope to collect hundreds of samples, thanks to the cooperation of hunters and game managers in 20 different states and provinces. If you are asked to contribute wings or tissue samples from grouse this year, please help out! A detailed summary and update on this project will be presented at the PGTC Meeting in November.

Minnesota Grouse, 2001for Management of Brushland Wildlife Habitat
by Bill Berg

After consecutive but slight sharptail population increases in the Northwest and East-Central Ranges for the last 4-5 years, sharptails dropped substantially in both zones this year to near-record lows. The range-wide decline of 37% resembled those of the Ruffed Grouse; sharptails are somewhat cyclic, but not to the extent Ruffed Grouse are. Survey cooperators included Division of Wildlife, Agassiz Refuge, and Minnesota Sharp-tailed Grouse Society volunteers.

In the East-Central Range, sharptail males on leks dropped 43%. Pine and Kanabec counties experienced the least decline (2%), but all other work areas declined 20% - 64%. Only 94 of the 160 leks checked (59%) had birds. These contained 646 males, and average of 6.9 per lek. Of the 143 leks that were also surveyed in 2000, males increased on 21%, declined on 76%, and were stable on 3%. East-Central sharptails are down about 80% from 1980 levels. In the Northwest Range, males on leks dropped 30%. The declines ranged from 12% - 60% in all work areas except northern Beltrami, which increased 1% (good work, Steve!). A total of 659 males were tallied on the 70 occupied leks (53%) that contained birds (9.4 per lek). Of the 110 leks that were also counted in 2000, 26% had more birds, 64% had fewer birds, and 10% were stable. Northwest sharptails are about 76% below 1980 levels. The similarities between the sharptail and Ruffed Grouse trends are striking, and suggest that similar forces were responsible for both declines.

The Wisconsin Prairie-Chicken
by Jim Keir

The prairie chicken here in Wisconsin has been referred to as “the most intensively managed grouse in North America.” Once found in every county, it is now a threatened species present only in the limited grassland habitat of the central part of the state. >

The 2001 spring census of booming males is complete. Because we have a limited range (and prairie-chicken numbers), we can make an attempt to survey all known locations. Our count of males is as close to complete as we can make it.

If we can assume that the number of booming males reflects the total population, there has been a 22% decline since the last survey in April, 2000. This decline was evident throughout the range, including Buena Vista and Leola Grasslands, our primary grassland management areas. There was a total of 586 males in 2001 (321 on Buena Vista and Leola) compared to 749 last year (411 on Buena Vista and Leola).

A combination of factors may have led to this recent decline, but my money is on the cool and wet spring last year. Production may have been reduced. Unfortunately a quick glance out the window any day for the past two weeks will tell you that central Wisconsin is again unusually cool and wet. It is now June 6 and the chickens are hatching! This raises questions about the upcoming level of production this summer.

Our “statewide” chicken survey each spring has identified areas of central Wisconsin with a limited amount of grassland on private lands, that have no public land, and that maintain low numbers of prairie chickens. We now have a priority effort targeted toward the improvement of grassland habitat on private lands in these areas. As many of you know, generating habitat management on private land and by private landowners can be a very tough nut to crack, but we have decided it is worth the effort. The timing may be critical because these small populations of prairie chickens seem to be declining.

These same areas have been identified as some of the best areas for songbird habitat management and restoration in this state. Results will have many benefits—this effort has a multiple-species focus.It is an undertaking with many partners, increasing the chance for success (and the potential for prairie chicken benefits!).

Missouri Update
by Larry Mechlin

We attempted complete censuses of Greater Prairie-Chicken males on leks in 1988, 1993 and every year since 1998 due to the dramatic declines in our population. In 2001, 281 males were counted on leks, down 13% from 2000 and 73% from 1993. Time is critical as work of the Grassland Coalition in nine focus areas, where our best populations remain, gains momentum. Counts this year were down in five focus areas from 2000 and stable in four others. Activities on focus areas included receipt of $50,000, $30,000 and $100,000 grants, $25,000 WHIP proposal, fall and summer burns including spot burning of pastures coupled with grazing experiments, grazing to control fescue and experimental light to moderate grazing for habitat improvement, woody removal on 600+ acres including work done in cooperation with AmeriCorp, workshops for citizens, landowners and teachers, installation of predator-proof fencing, chemical eradication of tall fescue, high mowing, leasing of wheat and lespedeza fields, and cost share on NWSG plantings

Kansas Prairie Grouse Survey Results - 2001
by Randy Rodgers
Kansas Dep. of Wildlife & Parks
Hays, Kansas

Greater Prairie-Chicken
The rangewide Greater Prairie-Chicken index was virtually unchanged (+2%) from 2000 this spring. Kansas’ easternmost survey routes, however, continue to decline and were down 23% this spring. The Flint Hills index was up 15% this spring, but this was not statistically significant. The Western Cropland was also little changed (-4%). Good numbers of Greater Prairie-Chickens are present in areas further west in northwest and west-central Kansas and the long-term trend appears to have been increasing. Kansas does not, however, have established prairie-chicken survey routes in these regions.

Lesser Prairie-Chicken
The rangewide index for Lesser Prairie-Chickens was little changed (+5%) compared to 2000 this year. New routes were run for the first time in Kiowa and Hodgeman counties this spring. The new Hodgeman County route produced the second-highest index of the 13 routes now established. This is a little surprising in that this survey area does not have a significant sand sagebrush component in the area (there is a little several miles west), but there is a fair amount of CRP along with the pretty well managed native range.

Efforts to continue documenting Lesser Prairie-Chicken pioneering in regions north of the Arkansas River in west-central Kansas continued this spring. During the springs of 1999 through 2001, displaying lessers have been audibly located at 165 sites in 16 counties north of the Arkansas. Lesser Prairie-Chickens are present in areas just south of Interstate 70. These birds currently overlap with Greater Prairie-Chickens in a band 40 to 50 miles wide and leks with both species present are surprisingly common. Hybridization is now evident.  Unusual-sounding chickens were detected in the spring of 2000 in a few places. This spring we were able to watch presumed hybrid males produce intermediate sounds on one lek and a hybrid bird was collected on another lek. In both cases, no evidence of hybrids was indicated when these two leks were first visited in 1999 and 2000. The most evident morphological characteristic of the hybrids seemed to be the tympanum which was colored similarly to those of Greater Prairie-Chicken, but considerable smaller in size. Subtle plumage differences were observed on the collected bird.

Colorado Lesser Prairie-Chicken Breeding Survey 2001
by Jeffrey A. Yost
Colorado Division of Wildlife

During the spring of 2001 Colorado Division of Wildlife personnel, U. S Forest Service employees from the Comanche National Grasslands, and volunteers from the public counted Lesser Prairie-Chickens (Tympanuchus pallidicinctus) on known established lek sites and conducted searches for new leks. This intensive effort put forth in 2001 was similar to that expended in 1998, with the exception of more time spent north of the Arkansas River in 2001. The increased effort to the north yielded the discovery of four new leks in Cheyenne and Kiowa counties. The intensive effort was somewhat reduced in Baca County due to a tremendous wind and snow storm on the second day of the scheduled three-day effort, sending many of the observers home early. The majority of counts and lek searches took place in April with some time spent in late March and early May.

Total bird count for 2001 was 298 with high-count totals for males of 181 and females of 52. Birds whose sex was unknown (65) were added into the high-count total, but were not used to calculate means for high male and female counts. Total number of active leks counted in 2001 was 30 with nine in Baca County, four in Cheyenne County (actually six because access was denied to two known leks, but birds could be heard on them), five in Kiowa County, and 12 in Prowers County. Of these leks, five were new: four in Cheyenne County and one in Prowers County.

This represents a decrease of 6% in total Lesser Prairie-Chicken numbers over counts conducted in 2000. Total bird count for 2000 was 317, with a high count for males of 211, females of 63, and 43 unknowns. Total number of active leks found in 2000 was 27, with nine in Baca County, one in Cheyenne (access was denied on private property where two known leks exist), six in Kiowa County, and 11 in Prowers County. Approximately 30% of Lesser Prairie-Chickens counted in 2000 were females compared to 22% females in 2001. This calculation does not use unknowns, only counts where sex could be distinguished.

Note: The high percentage of females counted in 2000 may be the result of inexperienced observers misidentifying males vs. females on leks. That may have occurred in 2001 as well.

The protocol for lek searches and counts included providing each participant with a topographic or county map showing locations of known leks or blocks of potential Lesser Prairie-Chicken habitat. Effort was also made to follow up any reports of potential prairie-chicken sightings received from the public or private landowners. The survey method consisted of arriving at the lek or block 30 minutes before sunrise and thoroughly looking and listening for birds within that general area until approximately 9:00 A.M. When a lek was located, every effort was made to count all males, all females and all unknowns to obtain a total bird count.

Attwater's Prairie-Chicken Update
by Mike Morrow
Attwater Prairie Chicken NWR

The Attwater’s Prairie-Chicken continues to teeter on the brink of extinction. Spring 2000 booming ground counts in the two remaining free-ranging populations found 22 males, down from 25 spring 1999. Supplementation with captively-reared birds continues to play a pivotal role in keeping wild populations from becoming extirpated. However, post-release survival has been very poor during the last two years. Fewer than 15% of birds released in late summer-early winter survived until 1 May of the following year. It is believed that drought conditions led to poor post-release survival during 1999. Delays in releasing birds in 2000 due to health issues in the captive flock resulted in releases occurring after wintering raptors had arrived. As a result, 2000 post-release survival was also very poor. Plans are to complete release of an estimated 100 captively-reared birds in August-September 2001 before migrant raptors arrive.

An attempt was made in spring 2001 to allow hens to nest in pens and then release the hen with her brood at hatch. Results were marginal, but merit further evaluation. Of four hens released with broods, one survived to a point where chicks should have been capable of independent survival.

Status of Sage-Grouse at the U. S. Army Yakima Training Center, Washington, 2001
by Phil Nyland
Environment and Natural Resources Division
U.S. Army
Yakima Training Center, Washington

Yakima Training Center (YTC), located in central Washington, supports one of two remaining populations of Greater Sage-Grouse in the state. In May 2001, the U. S. Fish and Wildlife Service determined that listing Greater Sage-Grouse in Washington as threatened under the Endangered Species Act is warranted but precluded by higher priority listing actions. Since 1989, monitoring has been conducted at YTC to track long-term trends in lek attendance and identify seasons and areas for lek protection. During Spring 2001, nine active leks were monitored and the male high count ranged from four to 31 birds (mean=10.9, S.E.=3.0). Since 1998, three leks have accounted for just over 70% of lek attendance. Attendance from 2000 to 2001 dropped 27% and 35% at two of three major leks. Surveys for new leks resulted in observations of two additional strutting grounds. The spring population estimate was 276, based on lek complex high count calculations. The population declined 9% from 2000, a trend similar to that observed in the north-central Washington population. In response to monitoring results, in 2001-2002, 18,125 ha of the installation will be managed to protect leks, and habitat for nesting and brood rearing, following a species management plan for the period 1998-2003.
