RENO, NV – U.S. Secretary of the Interior Sally Jewell announced that the U.S. Fish and Wildlife Service has determined that the Bi-State population of greater sage-grouse does not require the protection of the Endangered Species Act (ESA). Secretary Jewell joined with USDA Under Secretary Robert Bonnie, Nevada Governor Brian Sandoval, California Natural Resources Agency Secretary John Laird and other state and local partners to celebrate an extensive and long-term conservation partnership on behalf of the bi-state greater sagegrouse population. Federal, state and private partners have come together to proactively conserve key habitat and significantly reduce long-term threats to this distinct population segment of greater sagegrouse. A key factor in the decision not to list the bird was the development of The Bi-State Action Plan, a conservation plan developed by partners in the Bi-State Local Area Working Group over the past 15 years and secured with $45 million in funding. This adds to nearly $30 million worth of conservation work USDA and other partners have already completed to implement this plan. “Thanks in large part to the extraordinary efforts of all the partners in the working group to address threats to greater sage-grouse and its habitat in the Bi-State area, our biologists have determined that this population no longer needs ESA protection,” said Jewell. “What’s more, the collaborative, science-based efforts in Nevada and California are proof that we can conserve sagebrush habitat across the West while we encourage sustainable economic development.” “This is welcome news for all Nevadans. I applaud the local area working group, private citizens, Tribes, the Nevada Department of Wildlife and our federal partners for their tremendous efforts to develop conservation actions that preclude the need to list the species while still allowing for sustainable economic development,” said Sandoval. “Today’s announcement highlights the critical partnerships that must exist for our conservation strategies to be effective and demonstrate that sage grouse and economic development can coexist in both the bi-state area and across the range of the greater sage grouse.” “Together, we’ve worked with ranchers, conservation groups, local governments in Nevada and California to take proactive steps to restore and enhance sage-grouse habitat while also helping them improve their ranching operations,” Bonnie said. “The decision to not list the bi-state sage-grouse proves this work has paid off.” “The efforts of the local working group and the partnerships they’ve built over the past decade are truly unprecedented,” said Dan Ashe, U.S. Fish and Wildlife Service Director. “They have set the stage for the next generation of conservation and convinced us that the sage-grouse population has a bright future in the Bi-State region.” “California is committed to continue working with our public and private partners in implementing this strong, science-based conservation plan into the future,” said Laird. “This partnership between California and Nevada serves as a model for effective conservation of the Greater sage-grouse in other Western states.” As its name suggests, the Bi-State Distinct Population Segment straddles the California-Nevada border, where biologists estimate that between 2,500 and 9,000 of these ground-dwelling birds inhabit about 4.5 million acres of high-desert sagebrush. Greater sage-grouse are known for the males’ flamboyant springtime mating displays on traditional dancing grounds, also known as leks. The birds use a variety of sagebrush habitats throughout the year on private, state and federal lands. The U.S. Fish and Wildlife Service declared the Bi-State population of greater sage-grouse a Distinct Population Segment (DPS) under the ESA in 2010 because genetic analysis shows it has been separated from other greater sage-grouse for thousands of years and the genetic differences are significant. In October 2013, the Service proposed listing the Bi-State DPS as threatened under the ESA based on significant population declines due to the loss and fragmentation of its sagebrush habitat from urbanization and associated infrastructure development, encroachment of sagebrush by conifers, and a vicious cycle of wildfire and fire-adapted invasive grasses. These threats, combined with the relatively 4 Grouse News 49 Newsletter of the Grouse Group limited number of birds, the small population size and their isolation, were determined to pose a significant threat to the species. The Service is withdrawing this proposal in large part because of the success of the Bi-State Action Plan. The plan is the product of the Bi-State Area Local Working Group, comprising federal, state and local agencies and landowners from Nevada and California, which has been pursuing sage-grouse conservation since the early 2000s. Since then, the working group’s technical advisory committee has finalized plans on nearly 80 science-driven conservation projects specifically designed to reduce identified threats and protect the sagebrush-steppe habitat.

That research conducted primarily by Robert Weeden (Weeden 1965, Weeden and Theberge 1972) is one of the few long-term intensive research projects (1960-1969) on ptarmigan in the state. Once the 10-year intensive research project ended the Alaska Department of Fish and Game (ADF&G) continued to monitor spring breeding density of males for several years before focus shifted to management of large game and funding for small game projects was cut. Recently, however, there has been renewed support by ADF&G to pursue a more active approach to managing small game species. This renewed departmental support coupled with public concern over a perceived decline in the abundance of rock ptarmigan near Eagle Summit (110 kilometers northeast of Fairbanks) prompted efforts to re-establish monitoring and research in the area. In May of 2014, following methods described by Weeden (Weeden 1961), ADF&G personnel surveyed ¾ of his former study area at Eagle Summit to estimate spring breeding density of territorial male rock ptarmigan. Although a complete survey was not accomplished low numbers of male rock ptarmigan were observed (Carroll and Merizon 2014; http://www.adfg.alaska.gov/index.cfm?adfg=smallgamehunting.research). Roadside counts of territorial males along a stretch of the Steese Highway that bisects the study area corroborated the survey findings; observations were the lowest on record since roadside surveys began in 2007 (Carroll and Merizon 2014). ADF&G will begin a research project in the spring of 2015 aimed at gathering demographic and seasonal movement data to fill in knowledge gaps regarding rock ptarmigan population dynamics near Eagle Summit. The use of radio-transmitters will enable biologists to make direct estimates of survival and reproduction as well as provide information on seasonal movements. Specific biological data that will be collected include estimates of spring breeding density of territorial males, age-specific survival, nesting success, and chick production. Ultimately the data will be used to aid wildlife managers tasked with facilitating harvest management decisions. The opportunity to continue rock ptarmigan research and monitoring within a historical study area from which a long-term dataset exists is rare in this state and we are excited about this project. Please contact Cameron Carroll, ADF&G Small Game Biologist, at [email protected] if you have any questions or comments about this project. References Carroll, C. J., and R. A. Merizon. 2014.

Jackson, Sarah E. Gergel and Kathy Martin Wildlife in alpine ecosystems can be elusive and difficult to survey, yet knowledge of their distributions is critical as these habitats are threatened by climate change. Opportunistic “citizen science” observations submitted by hikers in remote alpine regions can be valuable, as coverage can be extensive compared to scientific field surveys. Citizen science initiatives have gained widespread support and recognition in the past decade, and can spread awareness about threatened species while providing data to document distributions of elusive species. The Vancouver Island subspecies of white-tailed ptarmigan (Lagopus leucura saxatilis) was designated as an endemic subspecies in 1939 based on unique morphological characteristics (Campbell et al., 1990; McTaggart-Cowan, 1939), and was blue-listed (vulnerable status) by the British Columbia government in 1992 given its endemic status and low density (Martin et al., 2004). We compare the performance of two regression (Generalized Linear Models and Generalized Additive Models) and three machine learning (Boosted Regression Trees, Random Forest, and Maxent) statistical modeling approaches and an ensemble model to predict the distribution of Vancouver Island white-tailed ptarmigan based on two datasets. The first dataset consists of ptarmigan presence locations from field surveys conducted by K. Martin and students from 1995-1999 using radio-telemetry and call-playbacks. The second dataset consists of opportunistic citizen science observations submitted by hikers. This citizen science program was initiated in partnership between the Strathcona Wilderness Institute and K. Martin in 1995. Notices were posted at trailheads within Strathcona Provincial Park describing distinguishing features of white-tailed ptarmigan. The notices requested that hikers report their ptarmigan sightings by mailing a card (or sending an e-mail) with GPS or map coordinates and photos (if possible) to K. Martin at UBC. The initiative began in 1995 and continues to the present, currently resulting in 404 confirmed white-tailed ptarmigan sightings. To model ptarmigan occurrence based on the two datasets, we included five topographic variables and four climate variables as predictor variables in the models. We predicted WTP occurrence over all of Vancouver Island at 100-m resolution. According to all of the models, the majority of suitable ptarmigan habitat corresponded with high elevations in the center of Vancouver Island, with small patches of suitable habitat in the relatively lower elevation southern and northern mountains. Most predicted suitable habitat was located inside Strathcona Provincial Park due to the fact that the park encompasses the highest mountains, and therefore the greatest expanse of alpine habitat on Vancouver Island. Model estimates of the area of suitable habitat varied from 370 to 1,039 km2 based on the field survey data and from 404 to 1,354 km2 based on the public data. All models had fair accuracy (kappa > 0.45) when tested on an independent dataset, but Generalized Linear Models and Generalized Additive Models tended to over-predict ptarmigan occurrence, had the lowest accuracy, and were most sensitive to the type of response data used. All the machine learning modeling techniques differed little between the datasets. Our results show that models trained on opportunistic citizen science data are similar in accuracy and spatial predictions to the more time and cost-intensive field survey data for an elusive alpine vertebrate. For white-tailed ptarmigan on Vancouver Island, citizen science data are comparable to data collected by professional scientists, and may be used as a stand-alone tool to monitor their distributions. Such similarities are encouraging for the increased use of opportunistic citizen science monitoring programs, particularly for species that are difficult or expensive to monitor by teams of field scientists and for questions at large spatial scales (e.g., entire species or subspecies ranges). Citizen science monitoring programs can save both time and expense while involving and educating the public about threatened species. We advocate the use of opportunistic citizen science data and machine learning modeling techniques (Random Forest, Boosted Regression Trees, and Maxent) for predicting alpine vertebrate species distributions.

A reconnaissance travel to the Okhotsk taiga in the Russian Far East Tobias Ludwig, Ralf Siano and Alexander V Andreev Introduction Due to their specific habitat requirements, forest grouse can be regarded indicators of old-growth forests with mosaics of different age-classes after natural disturbance. In the Far East of Russia, large-scale clearcutting threatens the Okhotsk taiga, an ecosystem with a high amount of old forest, characterized by dense dark-coniferous stands of Yezo-spruce Picea jezoensis. Siberian grouse Falcipennis falcipennis is endemic to the Russian Far East and exhibits a close functional relationship with Yezo-spruce (Hafner and Andreev 1998). It thus makes a good candidate of an indicator of intact natural forests in the Okhotsk-taiga. Habitat loss, fragmentation, and deterioration due to forestry are considered main threats to Siberian grouse (Andreev et al. 2001; Storch 2007). Clear-cut forestry interrupts and changes the natural succession cycle over large areas and particularly reduce the species´ winter habitat, which comprises stands of Yezo-spruce (Andreev and Hafner 2011). Large scale clear-cutting has reduced and degraded Siberian grouse habitat. Concurrently, habitat requirements of Siberian grouse are not yet fully understood. The species uses a variety of forest types over the year (Hafner and Andreev 1998) but habitat associations remain descriptive and have not yet been empirically tested. Furthermore, the species´ range-wide habitat status is unclear (Ludwig and Konovalenko 2012) and a reassessment of the species category according to IUCN guidelines seems to be warranted (Storch 2007). Due to the vastness and remoteness of the Russian Far East, remote sensing provides an important means to address these issues. In August and September 2014, we therefore travelled to the Russian Far East to collect Siberian grouse as well as Hazel grouse Tetrastes bonasia signs and forest structure data. Here we report first findings based on parts of the data. Methods Study areas We visited two areas in the Okhotsk-Manchurian taiga ecoregion within reach of Komsomol’sk na Amure (Figure 1). For a two-week period in late August/early September, and for another four days in late September, we went to the mountains of “Miochan” in the northern part of the Bureinsky range, about 60km west of Komsomol’sk na Amure (50°49’ N, 136°23’ E). The area stretches around a Lake “Amut”, at elevations between 300 and 1,300 m a.s.l. Forests are dominated by Yezo-spruce and Manchurian fir Abies nephrolepis with admixtures of Erman´s birch Betula ermanii, Siberian dwarf pine Pinus pumila, and Siberian rowan Sorbus sibirica and very high proportions of deadwood. Pure stands of dwarf pine can be found at the edge of boulder fields or on the mountaintops. Since a few years, the region is open for leisure activities such as cross-country- and downhill skiing/snowboarding with a tourist station at about 900m a.s.l. (see http://amutsnowlake.ru). 8 Grouse News 49 Newsletter of the Grouse Group Figure 1. Location of the two study areas within the Okhotsk-Manchurian Taiga (grey) in the Russian Far East. We visited the second study area between rivers “Charpin” and “Baktor” for two weeks in midSeptember. Interfluve “Charpin-Baktor” (51°16’N, 137°13’E) is at elevations between 100 and 400 m a.s.l. and characterized by a multitude of different forest types. Beside Yezo spruce and Manchurian fir, forests comprise of larch Larix gmelinii or mixed stands of larch and Manchurian birch Betula platyphylla or –oak Quercus mongolica. Further tree species are Korean pine Pinus koraiensis, poplar Populus tremula, alder Alnus hirsuta, maple Acer sp., willow Salix sp. and hazel Corylus manchurica. The area is ongoing subject to clear-cut forestry with concessions to Japanese and Korean companies in past years and to Chinese enterprises nowadays. Field sampling The timing of our fieldwork covered different life history stages of Siberian grouse. It included molting (August), seasonal migration to winter habitat when the Siberian grouse undertake short (1-2 km) movements (first half of September) as well as autumnal lekking (from mid-September onwards). We opportunistically mapped Siberian- and Hazel grouse signs along transects. We both, walked forest roads and off-track searching for indirect species signs such as feces, feathers, and dust bathes. We found dust bathes especially along forest road edges as well as in the roots of large fallen trees inside the forest. At random intervals, we provoked responses by hazel grouse with a whistle. For each sign but also for random points at intervals of about 200m along transects, we documented forest structure characteristics such as successional stage, proportion of tree species, canopy cover, rejuvenation cover, ground vegetation, and sighting distance for later analyses. We also sampled ground truth data for land cover classification of satellite images using a tablet computer with a panorama camera function. For each study area and grouse species, we calculated a simple relative density measure. Therefore, we divided the number of encounters by the total transect length. First discoveries Siberian grouse habitat features Key elements of Siberian grouse habitat throughout the year have been described by Hafner & Andreev (1998). We made seventy percent of our Siberian grouse observations in mature to old- and mixed-age spruce-fir (Miochan/ Charpin-Baktor) and larch forests stands (Charpin-Baktor). However, our first direct 9 Grouse News 49 Newsletter of the Grouse Group encounter with Siberian grouse (female) in Miochan was on a burned mountaintop (1,120m a.s.l.) with Pinus pumila, Ledum spec, and Rhododendron sp. (Figure 2). Presence of dust bathes and cowberry Vaccinium vitis-idaea made this site attractive for the bird (c.f. Hafner and Andreev 1998). Korean pine Pinus koraiensis is a common tree species in interfluve “Charpin-Baktor” (“lowland”) and dwarf pine Pinus pumila is as abundant in “Miochan” (“highlands”). The former species is rather specific for Komsomol’sk area (the protraction coming from Sikhote-Alin’), the latter covers Siberian grouse’s distribution range entirely. The both pines influence Siberian grouse habitat strongly through cone harvest →vole cycles → abundance of predators (chiefly owls and sables). It would be worth checking whether the cone cycles of these two pine species coincide across our study areas. Another specific habitat feature in Miochan is bog bilberry Vaccinium uliginosum. In September 2013 Siberian grouse ate these black berries intensely, producing black feces (Andreev pers. comm.). In 2014, we saw no V. uliginosum berries at all, but cowberries might have been a replacement. Small-scale edge structures or ecotones seem to be important for Siberian grouse. Beside forest roads, ecotones occur as small openings inside the forest, often with fallen trees and dust bath opportunities. We found a considerable amount of dust bathes, feathers, and feces when searching along these ecotone structures inside the forest. In Miochan, we found further edge structures at the transitions between spruce-fir forest plateaus and screes on south-facing slopes (Figure 3). In Charpin-Baktor, natural edges occur along swamps and creeks. Figure 2. A burned mountaintop with remnants of dwarf pine (above) was site of a direct observation of a juvenile Siberian grouse female (lower right). The species used piles of woody debris as dust bath (lower left). 10 Grouse News 49 Newsletter of the Grouse Group Figure 3. Forest openings (above) but also transition between spruce forest and scree (lower left) and forest roads (lower right; with Siberian grouse male) were ecotone structures attractive to Siberian grouse in Miochan. Autumnal lekking Autumnal lekking in Siberian grouse can be observed from end of August to early October (Hafner and Andreev 1998). We encountered lekking Siberian grouse cocks in both areas. In Charpin-Baktor we found a male on the 14th of September, lekking in old larch forest at the edge of a Ledum-swamp. In contrast, the lek in Miochan was right beside the forest road in old spruce-fir forest (Figure 4). While the cock in the lowland area was displaying in the evening (7.30 PM, UTC+11), we found the one in Miochan lekking at 11 AM (24th of September, UTC+11). This might be explained by the fact that three hens accompanied the second cock. These were resting on a fallen log but started taking up grid stones shortly after. 11 Grouse News 49 Newsletter of the Grouse Group Figure 4. Left: lekking Siberian grouse male in old larch forest in Charpin Baktor. Right: Siberian grouse lek in spruce-fir forest in the mountain area „Miochan“. Sympatric Siberian grouse and hazel grouse We found Siberian grouse occurring sympatric with hazel grouse in both study areas. Often, signs of both species were close together in geographical space. With feathers, we found indirect evidence that dust bathes at one location may be used by both species. Most likely, such a close coexistence is only possible when different age classes provide a heterogeneous forests mosaic. Comparison of relative densities in both areas revealed the encounter rate of Siberian grouse in “Miochan” to be twice the rate from the lowland area (Table 1) and vice versa for hazel grouse. Table 1. Relative densities (encounters per kilometer walked transect) of Siberian grouse and hazel grouse in the two study areas over a period of 12 days. Miochan Charpin – Baktor Siberian grouse 0.25 km-1 0.13 km-1 Hazel grouse 0.17 km-1 0.34 km-1 These numbers accord with the expectation that hazel grouse density is higher in the lowlands due to higher proportions of deciduous trees. Different encounter rates for Siberian grouse may be explained with differences in forest types and study area topography. On the other hand, both main habitat types - spruce-fir and larch forests, which provide winter- and summer food for the species, make up a considerable share in “Charpin-Baktor”. It is likely that many factors contribute to the difference, one of which is landscape-scale fragmentation due to clear-cut forestry. An interesting question in this respect is if forestry and road construction is a benefit for hazel grouse. Early forest succession as well as softwood stripes along forest roads may provide additional resources for hazel grouse. In the Russian Far East, hazel grouse seems to get abundant along with forestry. In 1987, Andreev (1990) found spring density of hazel grouse in “Charpin-Baktor” reaching 30-36 pairs/km2 in 15-20 year old cuts and many more remnants of spruce grouse than of hazel grouse. He supposed that numerous hazel grouse attract predators, which can easily switch to other species. We can only speculate here about forestry’s direct impact on the Siberian grouse population in this area. Nevertheless, it is a main source of habitat fragmentation. Figure 5 shows only a small part of interfluve “Charpin-Baktor”. Yet, forest fragmentation is clearly visible and its effects on sympatric Siberian- and hazel grouse should be further investigated. Later timing can possibly be excluded as a factor for decreased visibility in the lowlands. This is supported by the fact that we encountered 0.4 Siberian grouse per kilometer when coming back to Miochan for another four days after the two-week visit to Charpin-Baktor. Probably this second visit marked the beginning of juvenile dispersal and short migrations to the wintering areas. 12 Grouse News 49 Newsletter of the Grouse Group Figure 5.

White-edged markers show three Siberian grouse observations; one in a small 30-year old larch stand (SE) and two in old larch forest at the northwestern fringe of a Ledum-swamp. A new clear-cut from 2013 (indicated by the yellow cursor) separates the observations. Transects are black with random data collection points (blue). Summary and conclusions With endemic Siberian grouse as potential indicator of old forests; the planned project is designed to broaden our understanding about the impacts of forestry on the integrity of the Okhotsk-Manchurian taiga. In late summer 2014, we therefore collected Siberian grouse signs in a mountain and a lowland area of the Russian Far East. We found heterogeneous forests with deadwood, openings, and different ageclasses to be important not only for Siberian- but also for hazel grouse. First results suggest that Siberian grouse has higher densities at higher elevations whereas hazel grouse is more abundant in the lowlands. Research on the sympatric occurrence of both species may provide deeper understanding about the effects of forestry. Forestry that operates at smaller scales could facilitate faster regeneration and have less severe impact on the species (Hafner and Andreev 1998). Ski tourism is a rather new phenomenon in the mountains of the Russian Far East but may also have an impact on Siberian grouse populations in the future.

The mixed group and distribution overlap of some sister species in Xinjiang — is hybridization possible in these Galliformes? Roller MaMing and Guoqiang Zhang We'll discuss some recent observations on the Galliformes in Xinjiang, north-west China. The theory and the reality are so very different on the evolution, speciation and biogeography. These unusual events happen always in the special places, such as Xinjiang -- the intersection of the east-west confluence for some species. 1. Two species of snowcocks can be sympatric in portions of the Altun and Kunlun Mountains The Kunlun Mountains is located in the northern margin of the Tibetan Plateau, with branches such as Altun Mountains and the Qimantage Mountains. From 2011 to 2014, while conducting surveys for snowcocks in the Qimantage Mountains (89°00’E, 37°45’N, 4310m), we were surprised that we were able to photograph a group of about 30 snowcocks that included two different species, the Tibetan snowcock (Tetraogallus tibetanus) and Himalayan snowcock (Tetraogallus himalayensis) together in a mixed group during early mornings from May to Oct. According to the literature (Козлова, 1953; Shen and Wang, 1963), the occurrence of the two species together is an unprecedented event. Some researchers believe that all five species of snowcocks in the world are isolated in different mountains and by distance, with absolutely no opportunity for contact and exchange (Cheng et al., 1978). In the Kunlun Mountains, we know that even though their distribution in the plateau may overlap, there is strict elevational separation of the two species during the breeding season (Ma et al., 1991).

Two species of ptarmigan occurring together in Altai Mountains The Altai Mountains encompass four countries, Russia, Mongolia, Kazakhstan and China. These mountains are the most southern edge of willow ptarmigan (Lagopus lagopus) and rock ptarmigan (Lagopus muta) (Ma, 2011). In recent years, some birdwatchers were actually in one place (88°00’E, 48°00’N, 1800m) at the correct time to observe them together in summer. We were surprised again that these two species are so consistent in the body size, shape, colour, habits, food/feeding, habitat, and breeding season. Could they coexist for cooperating, mating, breeding and common prosperity? Perhaps they do. Willow ptarmigan (Lagopus lagopus) (left) in Altai Mountains (Photo by Tang Liming) and rock ptarmigan (Lagopus muta) (wright) in Altai Mountains (Photo by Zhao Lansheng). Such mixing occurs along the boundary areas of species distribution. These closely related species persist at the extremes, and perhaps climate change would lead to a change in the vertical distribution? Opposition and exclusion within the two similar species or sister species is a natural phenomenon and it is in line with the laws of nature. Natural isolation is an important factor in the evolution, speciation and biogeography. The integration or competition may lead to hybridization, genetic convergence, assimilation and species extinction. In this case, the two similar species are unlikely to achieve a "win-win" coexistence. In nature, the basis of evolution and persistence is the separation (isolation) of similar species. The possible hybrid zones and potential for parapatry within ptarmigan presents an interesting example of the challenge of defining distinct species or populations. Thoughts and opinions by other researchers would be of interest, and we 16 Chick of rock ptarmigan in Altai Mountains (Photo by Zhang Guoqiang). Grouse News 49 Newsletter of the Grouse Group hope that future discussion of this issue may be forthcoming.

Dwayne Elmore, Torre J. Hovick, Dirac Twidwell and Eric T. Thacker Lesser prairie-chickens (Tympanuchus pallidicinctus) and Attwater’s prairie-chickens (Tympanuchus cupido attwateri) are among the most at risk grouse in North America. The Attwater’s prairie-chicken was listed as endangered under the Endangered Species Act (ESA) in 1973. The lesser prairie-chicken was federally listed as a threatened species under the ESA in March of 2014. In a similar trend, greater prairie-chickens (Tympanuchus cupido pinnatus) have declined in number significantly from historic abundance. All of these grouse occupy portions of the southern Great Plains region, including Texas, Oklahoma, and Kansas. Prairie-chickens of the Great Plains require heterogeneous landscapes for survival (Hagen et al. 2004). These landscapes must provide areas with low-growing vegetation for lekking, moderate height vegetation for brooding, and tall, dense vegetation for nesting (Hagen et al. 2004, USFWS 2010). Furthermore, prairie-chickens require diverse plant communities with abundant forbs. In addition to providing an abundant food source directly, forbs often positively correlate with insect abundance, which is essential in the first 14 days of a chick’s life (Hagen et al. 2005). These various types of vegetation must occur simultaneously on the landscape within the home range of prairiechickens to sustain populations. Photo 1: Two Attwater’s prairie-chicken hens in loafing cover. Note the radio transmitter on the bird to the left (red circle). Photo: H. Starns. An additional topic of concern in the southern Great Plains is changes in historic fire regimes. Changes in wildfire activity have necessitated the development and implementation of fuels management strategies in the region. Prescribed fire is likely to be the dominant long-term fuels management strategy (USDI-BLM 2004). However, burning is frequently followed by the removal of grazing animals from the landscape (Fuhlendorf et al. 2012), which allows rapid recovery of herbaceous biomass (fine fuels). Thus, prescribed fire followed by grazing removal offers limited benefit as a fine fuel reduction strategy unless large areas are treated annually. Such large-scale treatments lead to homogeneous landscapes, removing structural and compositional complexity that exists in the southern Great Plains, and is not conducive to prairie-chicken ecology (Fuhlendorf et al. 2002). Moreover, prairie-chickens in the southern Great Plains region may be negatively affected by fuels management strategies that promote homogeneous landscapes. 18 Grouse News 49 Newsletter of the Grouse Group In order for prairie-chicken conservation objectives to coincide with fuels management objectives, fuels treatments must promote landscape heterogeneity while simultaneously reducing fire behavior characteristics (fire intensity, rate of spread) and increasing fire suppression potential. A management strategy known as patch-burning may promote both prairie-chicken conservation and fuels management objectives. Before European settlement, frequent patchy fires across the Great Plains interacted with large herbivores to promote heterogeneity in grassland structure and function throughout the region (Fuhlendorf and Engle 2001). Patch-burning replicates this interaction using carefully planned prescribed fire and subsequent grazing by large herbivores, such as cattle or bison (Bison bison). Furthermore, patch-burning has been shown to meet diverse habitat requirements of obligate grassland bird species in the Great Plains region (Fuhlendorf et al. 2006, Hovick et al. 2014). Photo 2: Two male Attwater’s prairie-chickens early in the booming season. Photo: H. Starns. Our research focuses on how and whether patch-burning can be implemented in the southern Great Plains for the benefit of lesser prairie-chickens, Attwater prairie-chickens, and greater prairiechickens while at the same time mitigating wildfire risk through fuels reduction. We are collecting vegetation (structure and fuels) data from four study sites: Packsaddle Wildlife Management Area and the Tallgrass Prairie Preserve in Oklahoma, as well as the Aransas National Wildlife Refuge and the Attwater’s Prairie-Chicken National Wildlife Refuge in Texas. These sites are comprised of vegetation types historically known to provide habitat for prairie-chicken populations: tallgrass prairie, sandshinnery oak and coastal prairie. Two of the sites (Tallgrass Prairie Preserve and Attwater’s PrairieChicken NWR) currently have prairie-chicken populations and monitoring programs for prairie-chicken habitat use which will be compared to the vegetation and fuels data collected to test for correlations between prairie-chicken life history stage, habitat use, and fuel parameters. Preliminary data from the first year of data collection suggest that time since fire is the main driver of heterogeneity as well as fuel measurements at each study site. We expect completion of this project in December 2016. References Fuhlendorf, S. D., and D. M. Engle. 2001.

The ceremony was performed by the Thuringian Prime Minister Bodo Ramelow in a festive atmosphere in the baroque hall of the State Chancellery in Erfurt. Many of Siegis companions and friends accepted the invitation to Erfurt. The ceremonies background were Siegis decades of commitment to nature- and species conservation and his contributions to the study of grouse worldwide. In his speech, the Prime Minister emphasized in particular Siegis merits to the designation of “Hainich”. Siegi had fought tirelessly for the designation of this beech forest national park. On behalf of the whole grouse community, we congratulate Siegi cordially! Tobias Ludwig & Christoph Unger Lesser Prairie-Chicken Initiative has launched its website! We're thrilled to announce the launch of our new website, www.lpcinitiative.org. On it, you'll find extensive information about LPCI: how we go about win-win conservation of lesser prairie-chickens and rural agriculture, how to take part in LPCI, in-depth natural history information on lesser prairie-chickens and the prairie community of which they are a part, news, photos, videos, and much more. We'll be regularly updating it with news, press releases, field reports, and photos. So stay tuned! www.lpcinitiative.org. Our mailing address is: [email protected]. Management of sandhills rangelands for greater prairie-chicken An Extension Circular is now available from the University of Nebraska-Lincoln for landowners in the Nebraska Sandhills. For the first time, landowners have management guidelines that are not based on research conducted in the tallgrass prairie region. The circular contains basic life history information, management suggestions, and a data sheet and monitoring scheme for landowners to use to track populations of prairie-chickens on their land. The circular may be of use to those who manage prairie chickens in other states outside of the tallgrass prairie region.
