  • A Home for Nature: Protected Areas Plan for the Island of Newfoundland
    A Home for Nature Protected Areas Plan for the Island of Newfoundland Acknowledgements This Protected Areas Plan for the Island of Newfoundland is the result of over 25 years of science advice, conservation planning, reserve site selection and assessment, resource industry assessments, discussions and negotiations. Although the process was lengthy and challenging, citizens should feel confident that the result is a well-considered and balanced contribution to sustainability of our province: for our environmental, economic and social well-being. The Wilderness and Ecological Reserves Advisory Council would like to acknowledge and thank all those who had a hand in development of the Plan: the Protected Areas Association; the Natural Areas System Plan Committee (1995-1996); the Natural Areas Plan Conflict Resolution Committee (2002-2003); the Western Newfoundland Model Forest; the Natural Areas System Plan Working Group (2006-2008); the Natural Areas System Plan Deputy Minister Steering Committee; past members of the Wilderness and Ecological Reserves Advisory Council; interdepartmental ad hoc committees (2000-2019) and staff from provincial government departments representing tourism, municipalities, forestry, mining, Indigenous affairs, environment and wildlife, that worked so hard over the years to bring this Plan forward. Finally, WERAC would like to thank all the people of Newfoundland and Labrador who have been involved in the establishment of our province’s existing wilderness and ecological reserves.

  • Arctic Hare (Lepus Arcticus Bangsii)
    The Status of Arctic Hare (Lepus arcticus bangsii) in Insular Newfoundland © Steve Sayles THE SPECIES STATUS ADVISORY COMMITTEE REPORT NO. 26 February 20, 2012 RECOMMENDED STATUS Recommended status: Current designation: DATA DEFICIENT None Criteria met: Data Deficient Reasons for designation: Uncertain taxonomic distinction Unknown area of occupancy Uncertain number of extant locations Unknown trend in number of locations Unknown habitat trend Uncertain population size Unknown population size trend Unknown if extreme population size fluctuations (>1 order of magnitude) This report was originally prepared by Brian Hearn and subsequently edited by the Species Status Advisory Committee. 2 STATUS REPORT Lepus arcticus bangsii (Rhoads, 1896) Arctic hare (Newfoundland population) lièvre arctique, Ukaliq Family: Leporidae (Hares and Rabbits) Life Form: Mammal Systematic/Taxonomic Clarifications This report examines the arctic hare population on the island of Newfoundland, a population within the subspecies Lepus arcticus bangsii, as a discrete and evolutionarily significant designatable unit because of its geographic and presumed reproductive isolation and its distinction as the southernmost population of arctic hare in North America. The taxonomy of the arctic or northern hare group(s) is disputed. Presently, three species of arctic (northern) hare are recognized: the Arctic hare (Lepus arcticus) occupying the tundra regions of Canada and along the coastal regions of Greenland; the Alaskan hare (Lepus othus) which is restricted to the western and northwestern regions of Alaska; and the Mountain hare (Lepus timidus) which is found throughout most of the Palaearctic region from Great Britain and Fennoscandia to eastern Siberia (Figure 1). Not surprisingly, the taxonomic status of these three species has been a long-standing controversy (Hall 1951, Best and Henry 1994).

Marvinney, Maine Geological Survey and IAT Maine, USA Paul Wylezol, IAT Newfoundland and Labrador, Canada Caledonia and Appalachia – neighbours on ancient continents, together in continental collisions that created great mountain ranges, separated by the opening of the Atlantic Ocean, brought back together by the International Appalachian Trail – a shared geological and cultural heritage Throughout human history, geodiversity has determined the location of settlements, trade routes, and human migratory paths, inextricably linking our culture to the geological foundations of our landscapes. The International Appalachian Trail (IAT) celebrates our common geoheritage by establishing a long-distance walking trail that extends beyond borders and jurisdictions to all regions once connected by the ‘Appalachian – Caledonian’ mountain range, formed more than 300 million years ago on the super-continent Pangaea. In addition to connecting people and place, the aim of the IAT is to promote natural and cultural heritage, environmental stewardship, health and fitness, fellowship and understanding, cross-border co-operation, and rural economic development through ecotourism and geotourism.

However, most examples were originally considered parts of enormous layered mafic See table of contents intrusions and so were interpreted in that light. The new understanding of ophiolites in the late 1960s and early 1970s was a crucial part of the global Earth Science revolution, and they are now central to all plate tectonic models Publisher(s) developed for ancient orogenic belts. Although their equivalence to oceanic crust is now well established, many ophiolites may not be ‘typical’ examples of The Geological Association of Canada such, and not all examples are identical. Most ophiolites likely formed in subduction-influenced environments rather than at mid-ocean ridges.
