Oreohelix land snails of Heart Mountain Ranch and Tensleep Preserve, Wyoming. Prepared by the Wyoming Natural Diversity Database, University of Wyoming for The Nature Conservancy. Mountain snails (Oreohelix sp.) are generally considered rare. In fact, Oreohelix peripherica wasatchensis is a candidate species in Utah under the Endangered Species Act, and several species of Oreohelix are considered critically imperiled by NatureServe. In Wyoming, Oreohelix pygmaea is an endemic species (only found in Wyoming) that lives in the Bighorn Mountains. Another species being watched in Wyoming and South Dakota is Oreohelix strigosa cooperi (referred to as Oreohelix cooperi by some), which is only found in the Black Hills and was petitioned for listing under the Endangered Species Act in 2006, but not listed. Oreohelix are relatively large land snails, but little is known about this genus. As their common names suggests, mountain snails live in mountainous regions of western North America. These land snails are active during wet, cool mouths of the year (i.e., early summer). Oreohelix carry their young internally until they are born at ~2.5 whorls. Mountain snails are one of the more obvious land snail genera, because of their large shell size (10-20 mm diameter).

  • A Preliminary Assessment of Paleontological Resources at Bighorn Canyon National Recreation Area, Montana and Wyoming
    A PRELIMINARY ASSESSMENT OF PALEONTOLOGICAL RESOURCES AT BIGHORN CANYON NATIONAL RECREATION AREA, MONTANA AND WYOMING Vincent L. Santucci1, David Hays2, James Staebler2 And Michael Milstein3 1National Park Service, P.O. Box 592, Kemmerer, WY 83101 2Bighorn Canyon National Recreation Area, P.O. Box 7458, Fort Smith, MT 59035 3P.O. Box 821, Cody, WY 82414 ____________________ ABSTRACT - Paleontological resources occur throughout the Paleozoic and Mesozoic formations exposed in Bighorn Canyon National Recreation Area. Isolated research on specific geologic units within Bighorn Canyon has yielded data on a wide diversity of fossil forms. A comprehensive paleonotological survey has not been previously undertaken at Bighorn Canyon. Preliminary paleontologic resource data is presented in this report as an effort to establish baseline data. ____________________ INTRODUCTION ighorn Canyon National Recreation Area (BICA) consists of approximately 120,000 acres within the Bighorn Mountains of north-central Wyoming and south-central Montana B (Figure 1). The northwestern trending Bighorn Mountains consist of over 9,000 feet of sedimentary rock. The predominantly marine and near shore sedimentary units range from the Cambrian through the Lower Cretaceous. Many of these formations are extremely fossiliferous. The Bighorn Mountains were uplifted during the Laramide Orogeny beginning approximately 70 million years ago. Large volumes of sediments, rich in early Tertiary paleontological resources, were deposited in the adjoining basins. This report provides a preliminary assessment of paleontological resources identified at Bighorn Canyon National Recreation Area. STRATIGRAPHY The stratigraphic record at Bighorn Canyon National Recreation Area extends from the Cambrian through the Cretaceous (Figure 2). The only time period during this interval that is not represented is the Silurian.

  • 2002 Forest Health Highlight, Wyoming 2002
    The Forest Resource Wyoming contains 9.8 million acres of forested lands. These forests provide many valuable resources including wood fiber, recreation, tourism, wildlife and fish habitat, cattle/sheep grazing, mineral resources, and water production. Approximately 4.3 million acres are used commercially for wood fiber production. Over 17,000 forested acres were harvested in 2002. Water from forested lands provides 19,437 miles of streams and 427,219 surface acres of lakes in Wyoming. Special Issues Wildfires - Four years of extensive, severe drought promoted a busy wildfire season in 2002 for Wyoming. Over 270 wildfires started in Wyoming during the year and burned over 56,000 acres of forest and range lands. Largest Wildfires Location Dates # of - (nearby Started - acres Wyoming towns) Ended burned 2002 Daley June 28 - Gillette 37,000 Complex July 16 Reese June 29 - Wheatland 19,334 Mountain July 11 South Fork June 30 - Lander 15,000 II July 20 June 7 - Hensel Wheatland 14,730 Aug.5 Aug.24 - Pass Creek Lander 13,433 Sept.9 Forest Health - "It's not a good time to be a conifer in WY," said an observer who was extensively traveling Wyoming's forests in 2002. In recent years, many bark beetle populations increased to outbreak and epidemic levels in these forests. The various bark beetle infestations are dramatically killing thousands of conifers throughout the forests in Wyoming. Adding to the beetle problems are disease problems affecting limber and whitebark pines, and subalpine firs. Mountain pine beetle, Dendroctonus ponderosae, attacks lodgepole, ponderosa, limber, and whitebark pines in Wyoming. This beetle is killing an estimated 200,000 pines in Wyoming.
