  • Native Or Suitable Plants City of Mccall

    Native Or Suitable Plants City of Mccall

    Native or Suitable Plants City of McCall The following list of plants is presented to assist the developer, business owner, or homeowner in selecting plants for landscaping. The list is by no means complete, but is a recommended selection of plants which are either native or have been successfully introduced to our area. Successful landscaping, however, requires much more than just the selection of plants. Unless you have some experience, it is suggested than you employ the services of a trained or otherwise experienced landscaper, arborist, or forester. For best results it is recommended that careful consideration be made in purchasing the plants from the local nurseries (i.e. Cascade, McCall, and New Meadows). Plants brought in from the Treasure Valley may not survive our local weather conditions, microsites, and higher elevations. Timing can also be a serious consideration as the plants may have already broken dormancy and can be damaged by our late frosts. Appendix B SELECTED IDAHO NATIVE PLANTS SUITABLE FOR VALLEY COUNTY GROWING CONDITIONS Trees & Shrubs Acer circinatum (Vine Maple). Shrub or small tree 15-20' tall, Pacific Northwest native. Bright scarlet-orange fall foliage. Excellent ornamental. Alnus incana (Mountain Alder). A large shrub, useful for mid to high elevation riparian plantings. Good plant for stream bank shelter and stabilization. Nitrogen fixing root system. Alnus sinuata (Sitka Alder). A shrub, 6-1 5' tall. Grows well on moist slopes or stream banks. Excellent shrub for erosion control and riparian restoration. Nitrogen fixing root system. Amelanchier alnifolia (Serviceberry). One of the earlier shrubs to blossom out in the spring.

EXECUTIVE SUMMARY Autumn willow, Salix serissima (Bailey) Fern., is an obligate wetland shrub that occurs in fens and bogs in the northeastern United States and eastern Canada. Disjunct populations of autumn willow occur in the Black Hills of South Dakota. Only two populations occur on Black Hills National Forest lands: a large population at McIntosh Fen and a small population on Middle Boxelder Creek.

    Transits of the Northwest Passage to End of the 2020 Navigation Season Atlantic Ocean ↔ Arctic Ocean ↔ Pacific Ocean

    TRANSITS OF THE NORTHWEST PASSAGE TO END OF THE 2020 NAVIGATION SEASON ATLANTIC OCEAN ↔ ARCTIC OCEAN ↔ PACIFIC OCEAN R. K. Headland and colleagues 7 April 2021 Scott Polar Research Institute, University of Cambridge, Lensfield Road, Cambridge, United Kingdom, CB2 1ER. <[email protected]> The earliest traverse of the Northwest Passage was completed in 1853 starting in the Pacific Ocean to reach the Atlantic Oceam, but used sledges over the sea ice of the central part of Parry Channel. Subsequently the following 319 complete maritime transits of the Northwest Passage have been made to the end of the 2020 navigation season, before winter began and the passage froze. These transits proceed to or from the Atlantic Ocean (Labrador Sea) in or out of the eastern approaches to the Canadian Arctic archipelago (Lancaster Sound or Foxe Basin) then the western approaches (McClure Strait or Amundsen Gulf), across the Beaufort Sea and Chukchi Sea of the Arctic Ocean, through the Bering Strait, from or to the Bering Sea of the Pacific Ocean. The Arctic Circle is crossed near the beginning and the end of all transits except those to or from the central or northern coast of west Greenland. The routes and directions are indicated. Details of submarine transits are not included because only two have been reported (1960 USS Sea Dragon, Capt. George Peabody Steele, westbound on route 1 and 1962 USS Skate, Capt. Joseph Lawrence Skoog, eastbound on route 1). Seven routes have been used for transits of the Northwest Passage with some minor variations (for example through Pond Inlet and Navy Board Inlet) and two composite courses in summers when ice was minimal (marked ‘cp’).

Yet, we still lack knowledge of the spatio- temporal dynamics of many Arctic organisms and how they are affected by local and regional processes. The Arctic hare (Lepus arcticus) is a large lagomorph endemic to high Arctic environments in Canada and Greenland. Current knowledge about this herbivore is scarce and the temporal and spatial dynamics of their populations are poorly understood. Here we present observations on Arctic hares in two sites on north Greenland (Hall and Washington lands) and one adjacent site on Ellesmere Island (Judge Daly Promontory). We recorded a large range of group sizes from 1 to 135 individuals, as well as a substantial variation in hare densities among the three sites (Hall land: 0 animals / 100 km2, Washington land 14.5-186.7 animals / 100 km2, Judge Daly Promontory 0.18-2.95 animals / 100 km2).
