Department of Environment– Wildlife Division Wildlife Research Section Department of Environment Box 209 Igloolik, NU X0A 0L0 Tel: (867) 934-2179 Fax: (867) 934-2190 Email: [email protected] Frequently Asked Questions Government of Nunavut 1. What is the role of the GN in issuing wildlife research permits? On June 1, 1999, Nunavut became Canada’s newest territory. Since its creation, interest in studying its natural resources has steadily risen. Human demands on animals and plants can leave them vulnerable, and wildlife research permits allow the Department to keep records of what, and how much research is going on in Nunavut, and to use this as a tool to assist in the conservation of its resources. The four primary purposes of research in Nunavut are: a. To help ensure that communities are informed of scientific research in and around their communities; b. To maintain a centralized knowledgebase of research activities in Nunavut; c. To ensure that there are no conflicting or competing research activities in Nunavut; and d. To ensure that wildlife research activities abide by various laws and regulations governing the treatment and management of wildlife and wildlife habitat in Nunavut. 2. How is this process supported by the Nunavut Land Claims Agreement? Conservation: Article 5.1.5 The principles of conservation are: a. the maintenance of the natural balance of ecological systems within the Nunavut Settlement Area; b. the protection of wildlife habitat; c. the maintenance of vital, healthy, wildlife populations capable of sustaining harvesting needs as defined in this article; and d. the restoration and revitalization of depleted populations of wildlife and wildlife habitat. -

In this review, we focus on the effects of human disturbance on terrestrial apex predators. We summarize their ecological role in nature and how they respond to different sources of human disturbance. Apex predators control their prey and smaller predators numerically and via behavioral changes to avoid predation risk, which in turn can affect lower trophic levels. Crucially, reducing population numbers and triggering behavioral responses are also the effects that human disturbance causes to apex predators, which may in turn influence their ecological role. Some populations continue to be at the brink of extinction, but others are partially recovering former ranges, via natural recolonization and through reintroductions. -
Lesser Snow Goose EN
Introduction This bird • has evolved a strong serrated bill and tongue to cut and tear the roots of bulrushes and sedges • often has a rusty orange face, because its feathers have been stained by iron in the earth where the bird feeds • is probably the most abundant goose in Canada • unlike most other waterfowl, usually nests in large colonies with densities of up to 2 000 pairs per square kilometre Description The Lesser Snow Goose Chen caerulescens caerulescens has two different appearances, white phase and blue phase. The plumage of white-phase geese is almost completely white, except for black wing tips. The blue-phase goose has a white head, a bluish colour on the feathers of the lower back and flanks, and a body that ranges in colour from very pale, almost white, to very dark. Both the white- and blue-phase snow geese frequently have rusty orange faces, because their feathers have been stained by iron in the earth where the birds feed. The downy goslings of the white-phase geese are yellow, those of the blue phase nearly black. By two months of age the young birds of both colour phases are grey with black wing tips, although the immature blue-phase birds are generally a darker grey and have some light feathers on the chin and throat, which can become stained like those of the adults. The goslings have mostly lost their grey coloring by the following spring; in April and May they may only show a few flecks of darker coloring on their head and neck, and a few grey feathers on their wings that distinguish them from adults. -

Restoration of Heterogeneous Disturbance Regimes for the Preservation of Endangered Species Steven D
RESEARCH ARTICLE Restoration of Heterogeneous Disturbance Regimes for the Preservation of Endangered Species Steven D. Warren and Reiner Büttner ABSTRACT Disturbance is a natural component of ecosystems. All species, including threatened and endangered species, evolved in the presence of, and are adapted to natural disturbance regimes that vary in the kind, frequency, severity, and duration of disturbance. We investigated the relationship between the level of visible soil disturbance and the density of four endan- gered plant species on U.S. Army training lands in the German state of Bavaria. Two species, gray hairgrass (Corynephorus canescens) and mudwort (Limosella aquatica), showed marked affinity for or dependency on high levels of recent soil disturbance. The density of fringed gentian (Gentianella ciliata) and shepherd’s cress (Teesdalia nudicaulis) declined with recent disturbance, but appeared to favor older disturbance which could not be quantified by the methods employed in this study. The study illustrates the need to restore and maintain disturbance regimes that are heterogeneous in terms of the intensity of and time since disturbance. Such a restoration strategy has the potential to favor plant species along the entire spectrum of ecological succession, thereby maximizing plant biodiversity and ecosystem stability.

Disturbance Processes and Ecosystem Management
Vegetation Management and Protection Research DISTURBANCE PROCESSES AND ECOSYSTEM MANAGEMENT The paper was chartered by the Directors of Forest Fire and Atmospheric Sciences Research, Fire and Aviation Management, Forest Pest Management, and Forest Insect and Disease Research in response to an action item identified in the National Action Plan for Implementing Ecosystem Management (February 24, 1994). The authors are: Robert D. Averill, Group Leader, Forest Health Management, Renewable Resources, USDA Forest Service Region 2, 740 Sims St., Lakewood, CO 80225 Louise Larson, Forest Fuels Management Specialist, USDA Forest Service Sierra National Forest, 1600 Tollhouse Road, Clovis, CA 93612 Jim Saveland, Fire Ecologist, USDA Forest Service Forest Fire & Atmospheric Sciences Research P.O. Box 96090, Washington, DC 20090 Philip Wargo, Principal Plant Pathologist, USDA Forest Service Northeastern Center for Forest Health Research, 51 Mill Pond Road, Hamden, CT 06514 Jerry Williams, Assistant Director, Fire Operations, USDA Forest Service Fire & Aviation Management Staff, P.O. Box 96090, Washington, DC 20090 Melvin Bellinger, retired, made significant contributions. Abstract This paper is intended to broaden awareness and help develop consensus among USDA Forest Service scientists and resource managers about the role and significance of disturbance in ecosystem dynamics and, hence, resource management. To have an effective ecosystem management policy, resource managers and the public must understand the nature of ecological resiliency and stability and the role of natural disturbance on sustainability. Disturbances are common and important in virtually all ecosystems. Executive Summary "Ecosystems are not defined so much by the objects they contain as by the processes that regulate them" -- Christensen and others 1989 Awareness and understanding of disturbance ecology and the role disturbance plays in ecosystem dynamics, and the ability to communicate that information, is essential in understanding ecosystem potentials and the consequences of management choices. -

Identification Field Guide to the Geese of the Willamette Valley and Lower Columbia River, 2nd Edition 68 History Populations of greater white-fronted geese, commonly known as specs or speckle bellies, found in the Pacific Flyway have fluctuated for the past several decades. Currently, the Pacific population is increasing and is above flyway management objectives. Most white-fronted geese winter in the Central Valley of California, but white-fronts are observed and harvested in the permit zone every year. Currently, they are not common in our region, but appear to be increasing. -
