That distinction belongs to Father Louis was often referred to as the Mountain, and of course Hennepin, the Recollect priest who was the first it is still called that in Hamilton and Grimsby today. European to describe Niagara Falls from personal We in eastern Niagara have largely forgotten the observation. In his Description de la Louisiane, name, though it survives in the City of Thorolds published in 1683, five years after his visit, he speaks motto Where the Ships Climb the Mountain. of le grand Sault de Niagara, and labels it thus on the accompanying map. This is the form that So when did the name Niagara Escarpment first prevails thereafter, and it is the spelling used for Fort come into use? And what about the areas other de Niagara, established by the French at the mouth Niagara names, like Niagara Falls, Niagara River of the river in 1726.

  • Papilio Glaucus, P. Marcellus, P. Philenor, Pieris Rapae, Colias Philo Dice, Antho­ Caris Genutia, Anaea Andria, Euptychia Gemma
    102 REMINGTON: 1952 Central Season Vol.7, nos.3·4 Papilio glaucus, P. marcellus, P. philenor, Pieris rapae, Colias philo dice, Antho­ caris genutia, Anaea andria, Euptychia gemma. One exception to the general scarcity was the large number of Erynnis brizo and E. juvenalis which were seen clustered around damp spots in a dry branch on April 9. MERRITT counted 67 Erynnis and 2 Papilio glaucus around one such spOt and 45 Erynnis around another. Only one specimen of Incisalia henrici was seen this spring. MERRITT was pleased to find Incisalia niphon still present in a small tract of pine although the area was swept by a ground fire in 1951. Vanessa cardui appeared sparingly from June 12 on, the first since 1947. In the late summer the season appeared normal. Eurema lisa, Nathalis iole, Lycaena thoe, and Hylephila phyleus were common. Junonia coenia was more abundant around Louisville than he has ever seen it. A rarity taken in Louisville this fall was Atlides halesus, the first seen since 1948. The latest seasonal record made by Merritt was a specimen of Colias eury­ theme flying south very fast on December 7. EDWARD WELLING sent a record of finding Lagoa crispata on June 27 at Covington.

  • Strategic Plan
    STRATEGIC PLAN Municipality of Northern Bruce Peninsula June 2008 Revised July 2015 Municipality of Northern Bruce Peninsula Page 1 of 11 Strategic Plan Revised July 2015 MUNICIPALITY OF NORTHERN BRUCE PENINSULA STRATEGIC PLAN Northern Bruce Peninsula is a municipal corporation that commenced operations on January 1, 1999. It encompasses the former Townships of Eastnor, Lindsay and St. Edmunds and the Village of Lion’s Head. Many other hamlets within NBP are Tobermory, Stokes Bay, Pike Bay, Miller Lake, Barrow Bay, Ferndale, Dyers Bay and the Lindsay 20 communities. The Municipality of Northern Bruce Peninsula is the northerly neighbouring community to South Bruce Peninsula, Highway 6 traverses northerly through NBP. The peninsula itself is surrounded on the east by Georgian Bay and on the west by Lake Huron. We are home to Fathom Five National Marine Park, Bruce Peninsula National Park, the Bruce Trail, Niagara Escarpment, UNESCO World Biosphere, Cabot Head and Lion’s Head Nature Reserves, two First Nations Hunting Reserves and a large Bruce County Forest Tract. NBP covers an area of 781.51 square kilometers boasting a permanent population of 3,900 year round residents and just over 5000 households. The Public Works Department maintains 475 kilometres of roads and streets, some of which are paved, some gravelled. Some roads provide year round access while others enjoy only summer accessibility. In 2004, NBP was proclaimed as a “dark sky community” in the hope of preserving and protecting the night time environment and our heritage of dark skies through the use of quality outdoor lighting and goals established which are intended to stop the adverse effects of light pollution.

  • Dytiscid Water Beetles (Coleoptera: Dytiscidae) of the Yukon
    Dytiscid water beetles of the Yukon FRONTISPIECE. Neoscutopterus horni (Crotch), a large, black species of dytiscid beetle that is common in sphagnum bog pools throughout the Yukon Territory. 491 Dytiscid Water Beetles (Coleoptera: Dytiscidae) of the Yukon DAVID J. LARSON Department of Biology, Memorial University of Newfoundland St. John’s, Newfoundland, Canada A1B 3X9 Abstract. One hundred and thirteen species of Dytiscidae (Coleoptera) are recorded from the Yukon Territory. The Yukon distribution, total geographical range and habitat of each of these species is described and multi-species patterns are summarized in tabular form. Several different range patterns are recognized with most species being Holarctic or transcontinental Nearctic boreal (73%) in lentic habitats. Other major range patterns are Arctic (20 species) and Cordilleran (12 species), while a few species are considered to have Grassland (7), Deciduous forest (2) or Southern (5) distributions. Sixteen species have a Beringian and glaciated western Nearctic distribution, i.e. the only Nearctic Wisconsinan refugial area encompassed by their present range is the Alaskan/Central Yukon refugium; 5 of these species are closely confined to this area while 11 have wide ranges that extend in the arctic and/or boreal zones east to Hudson Bay. Résumé. Les dytiques (Coleoptera: Dytiscidae) du Yukon. Cent treize espèces de dytiques (Coleoptera: Dytiscidae) sont connues au Yukon. Leur répartition au Yukon, leur répartition globale et leur habitat sont décrits et un tableau résume les regroupements d’espèces. La répartition permet de reconnaître plusieurs éléments: la majorité des espèces sont holarctiques ou transcontinentales-néarctiques-boréales (73%) dans des habitats lénitiques. Vingt espèces sont arctiques, 12 sont cordillériennes, alors qu’un petit nombre sont de la prairie herbeuse (7), ou de la forêt décidue (2), ou sont australes (5).

  • Driftless Area National Wildlife Refuge
    DRIFTLESS AREA NATIONAL WILDLIFE REFUGE McGregor, Iowa ANNUAL NARRATIVE REPORT FY2006 DRIFTLESS AREA NATIONAL WILDLIFE REFUGE McGregor, Iowa Fiscal Year 2006 _________________________ Prepared by Date _________________________ ______________________________ Refuge Manager Date Complex Manager Date ______________________________ Regional Chief, NWRS Date INTRODUCTION 1. Location The Driftless Area National Wildlife Refuge was established in 1989 for the protection and recovery of the threatened Northern monkshood and endangered Iowa Pleistocene snail. These species occur on a rare habitat type termed algific talus slopes. These are slopes with outflows of cold underground air that provide a glacial relict habitat to which certain species have adapted (see diagram below). The Driftless Area National Wildlife Refuge consists of ten units scattered throughout Allamakee, Clayton, Dubuque, and Jackson Counties in northeast Iowa. Total Refuge acreage is 811 acres with individual units ranging from 6 to 208 acres. Acquisition targets not only the algific slope, but surrounding buffer habitat that includes sinkholes important to air flow to the slope. Acquisition is ongoing, but limited due to insufficient funds. 2. Topography Refuge units are primarily forested and generally consist of steep topography with narrow creek valleys, large rock outcroppings, and karst features. Riparian and grassland habitat also occur on the Refuge. 3. Points of Interest The algific talus slope habitat of the Refuge harbors many unusual and rare plant and land snail species, some of which are also on the state threatened and endangered species list. These areas tend to be scenic with cliffs and rock outcroppings, springs, and coldwater streams. 4. Physical Facilities The Refuge office is located at the McGregor District of the Upper Mississippi River National Wildlife and Fish Refuge, McGregor, Iowa.
