Moseley Natural Heritage Section Nongame/Endangered Wildlife Program Bureau of Wildlife December 1990 Idaho Department of Fish and Game 600 South Walnut, P.O. Box 25 Boise, Idaho 83707 Jerry M. Conley, Director Cooperative Challenge Cost-share Project Sawtooth National Forest Idaho Department of Fish and Game Purchase Order No. 40-0261-0-0801 ABSTRACT An inventory for Astragalus vexilliflexus var. nubilus (White Cloud milkvetch) was conducted on the Sawtooth National Forest by the Idaho Department of Fish and Game's Natural Heritage Program during August of 1990. The inventory was a cooperative Challenge Cost-share project between the Department and the Sawtooth National Forest. White Cloud milkvetch is a narrow endemic to the White Cloud Peaks and Boulder Mountains of central Idaho, in Custer County. Populations are scattered along the ridge systems that slope generally west to east on the east side of the White Cloud crest. Additionally, one population from the Bowery Creek drainage of the Boulder Mountains is known. It is a high elevation species, found mostly on exposed, dry, rocky ridge crests or upper slopes that typically support a relatively sparse vegetation cover. Prior to our 1990 survey, the species was known from three populations. Five new populations were discovered during the 1990 field investigation. Together, these eight populations support approximately 5,700 plants and cover an area less than 40 acres. Both current and potential threats have been identified at several populations.

We spent almost a week on training before crews dispersed to the field. We have two bear capture teams and one hair collection team in the Cabinet-Yaak plus one trap team and two hair collection teams in the Selkirk Mountains. Crews began capture and hair collection efforts on May 18. Capture efforts will emphasize recapture of existing collar bears. The manufacturer of our radio collars alerted us to a software glitch that is causing many of our collars to malfunction. This year’s collars have had the software updated to avoid the issue. Selkirk Mountains Research Monitoring We began 2019 with five grizzly bears collared in the Selkirk Mountains (3 females and 2 males). Capture activities have resulted in the recapture and collar change on one of the females (Figure 1). Trail cameras at the capture site indicated she was accompanied by a 2 year-old offspring, but that bear was not captured. Trapping will continue near the international border to attempt recapture of the other two females. Cabinet-Yaak Research Monitoring We began 2019 with six collared grizzly bears in the Cabinet-Yaak (2 females and 4 males). One of the females was observed in May with two new cubs.

Fort Collins, CO: U.S. Department of Agriculture, Forest Service, Rocky Mountain Research Station. 129 p. A representativeness assessment of National Forest System (N FS) Research Natural Areas in ldaho summarizes information on the status of the natural area network and priorities for identification of new Research Natural Areas. Natural distribution and abundance of plant associations is compared to the representation of plant associations within natural areas. Natural distribution and abundance is estimated using modeled potential natural vegetation, published classification and inventory data, and Heritage plant community element occur- rence data. Minimum criteria are applied to select only viable, high quality plant association occurrences. In assigning natural area selection priorities, decision rules are applied to encompass consideration of the adequacy and viability of representation. Selected for analysis were 1,024 plant association occurrences within 21 4 natural areas (including 115 NFS Research Natural Areas). Of the 1,566 combinations of association within ecological sections, 28 percent require additional data for further analysis; 8, 40, and 12 percent, respectively, are ranked from high to low conservation priority; 13 percent are fully represented. Patterns in natural area needs vary between ecological section. The result provides an operational prioritization of Research Natural Area needs at landscape and subregional scales.

    SEASONAL STATUS OF THE AMERICAN PIPIT IN IDAHO DANIEL M. TAYLOR, 244 N. 12th, Pocatello,Idaho 83201 In Idaho, the AmericanPipit (Antbus rubescens)has been considered primarilya migrant,either locally common but erratic (Larrison et al. 1967) or uncommonin springand commonin fall (Burleigh1972). Severalother writers(Merriam 1891, Merrill 1898, Newhouse1960, Levy 1962) consid- ered it an abundantfall migrantbut gaveno indicationof actualnumbers. The one (Larrisonet al. 1967) or two (Burleigh1972) winterrecords were from Lewiston.Larrison et al. (1967) suspectedthat pipitsmight breed on someof the state'shigh mountains,while Burleigh(1972) knew of only Merriam's(1891) statementthat they breedin the Salmon River Mountains and a report by L. B. McQueenof breedingin the upper Pahsimeroi drainagenear Borah Peak. This scantinessof breedingevidence may be why the mostrecent A.O.U. checklist(1983) statesthat the AmericanPipit breedslocally on mountaintopsin severalRocky Mountain states but does not specificallylist Idaho. In this paper I consolidateand enhancewhat is known aboutAmerican Pipit distributionin Idaho with reference to adjacent areas.

I cannot confirm the big fish stories.

I’ve seen photos and heard several reports that the fishing is excellent for big Cutthroat. Unfortunately, the relentless wind made the wind chill unbearable and I was relegated to bundling up and bagging a couple of peaks instead. But trust me – I have no regrets! The scenery is spectacular and possibly my favorite in Idaho. The Boulder-White Cloud Mountains are part of the Sawtooth National Recreation Area. The fight has continued for decades to designate the Boulder-White Clouds a Wilderness Area. I personally think it rivals the Sawtooths as my favorite backpacking destination in Idaho and I’ve set foot in most mountain ranges save a few in the panhandle.
