    United States Department of Agriculture Wilderness Visitors and Forest Service Recreation Impacts: Baseline Rocky Mountain Research Station Data Available for Twentieth General Technical Report RMRS-GTR-117 Century Conditions September 2003 David N. Cole Vita Wright Abstract __________________________________________ Cole, David N.; Wright, Vita. 2003. Wilderness visitors and recreation impacts: baseline data available for twentieth century conditions. Gen. Tech. Rep. RMRS-GTR-117. Ogden, UT: U.S. Department of Agriculture, Forest Service, Rocky Mountain Research Station. 52 p. This report provides an assessment and compilation of recreation-related monitoring data sources across the National Wilderness Preservation System (NWPS). Telephone interviews with managers of all units of the NWPS and a literature search were conducted to locate studies that provide campsite impact data, trail impact data, and information about visitor characteristics. Of the 628 wildernesses that comprised the NWPS in January 2000, 51 percent had baseline campsite data, 9 percent had trail condition data and 24 percent had data on visitor characteristics. Wildernesses managed by the Forest Service and National Park Service were much more likely to have data than wildernesses managed by the Bureau of Land Management and Fish and Wildlife Service. Both unpublished data collected by the management agencies and data published in reports are included. Extensive appendices provide detailed information about available data for every study that we located. These have been organized by wilderness so that it is easy to locate all the information available for each wilderness in the NWPS. Keywords: campsite condition, monitoring, National Wilderness Preservation System, trail condition, visitor characteristics The Authors _______________________________________ David N.

We used eight-day composites of surface reflectance data at 500-m spatial resolution, along with historical lightning-caused fire occurrences during the 2005–2016 period, derived from a Moderate Resolution Imaging Spectroradiometer. First, we calculated the normalized difference water index (NDWI) as an indicator of vegetation/fuel water content over the six natural subregions of interest. Then, we generated the subregion-specific annual dynamic median NDWI during the 2005–2012 period, which was assembled into a distinct pattern every year. We plotted the historical lightning-caused fires onto the generated patterns, and used the concept of cumulative frequency to model lightning-caused fire occurrences. Then, we applied this concept to model the cumulative frequencies of lightning-caused fires using the median NDWI values in each natural subregion.

  • Dodging the 'Perfect Storm'
    Dodging the ‘Perfect Storm’ Conservation Ontario’s Business Case for Strategic Reinvestment in Ontario’s Flood Management Programs, Services, and Structures September 2013 Introduction Flooding in Calgary, Alberta and more recently in Toronto, Ontario reminds us just how vulnerable we are when it comes to extreme weather events. The loss of life, devastation, long term social and economic disruption and the staggering cleanup costs in the aftermath of these floods clearly demonstrates how essential it is to have actionable guidelines, policies and programs in place to manage these events. Flooding in downtown Calgary (2013). Source: CTV News Flooding on the Don Valley Parkway, Toronto (2013). Source: CTV News 1 Dodging the ‘Perfect Storm’ – Conservation Ontario’s Business Case for Strategic Reinvestment in Ontario’s Flood Management Programs and Services, and Structures (2013) In Ontario, flooding is the leading cause of public emergency.1 To date, Ontario’s programs to manage floods and regulate floodplains have proven extremely effective and, indeed, the Ontario government has been a leading jurisdiction in Canada for flood planning and management. While much has been accomplished, several factors, if not addressed directly and quickly, will significantly jeopardize the ability of Conservation Authorities and all levels of governments to maintain and improve on this level of management and protection. Flood management is a shared responsibility in Ontario and Conservation Authorities are on the front lines of the Provincial Flood Forecasting and Warning program. In addition, Conservation Authorities bring added protection and benefits through watershed planning, watershed stewardship/natural heritage system management, monitoring and many other programs they deliver.

  • 10 896 Zanatta 6.Indd
    2011 NORTHEASTERN NATURALIST 18(1):1–6 Confi rmation of Obovaria olivaria, Hickorynut Mussel (Bivalvia: Unionidae), in the Mississagi River, Ontario, Canada David T. Zanatta1,* and Daelyn A. Woolnough1 Abstract - A signifi cant and recruiting population of Obovaria olivaria (Hickorynut Mussel) was confi rmed in the Mississagi River, Lake Huron drainage, ON, Canada. This large river unionid mussel is known to use Acipenser fulvescens (Lake Sturgeon) and Scaphirhynchus platorynchus (Shovelnose Sturgeon) as hosts. The Mississagi River is known to have a spawning Lake Sturgeon population. In 9.1 person-hours of snorkel and SCUBA searches, 10 live O. olivaria ranging in length from 36 to 79 mm, including six gravid females, were collected in sandy substrates with water depths from 1.5 to 4 m. Obovaria olivaria in the Mississagi River represent a signifi cant range disjunction from the other extant populations in Canada in the Ottawa and St. Lawrence river drainages. As the conservation status of this rare mussel in Canada is assessed, the geographic genetic population structure and spatial extent among known areas should be studied to under- stand the post-glacial redistribution of the species. Introduction Obovaria olivaria (Rafi nesque) (Hickorynut Mussel), is a deepwater, large river unionid that can be abundant in the Mississippi basin of central North Amer- ica (Parmalee and Bogan 1998, Williams et al. 2008). In contrast, O. olivaria is a rare mussel in the St. Lawrence River and Great Lakes watershed of central North America (Clarke 1981, Metcalfe-Smith et al. 2005, NatureServe 2009) and is cur- rently under assessment by the Committee on the Status of Endangered Wildlife in Canada (COSEWIC).

  • Lake Ontario Biodiversity Conservation Strategy, Workshop 1
    LAKE ONTARIO • ~ )> "' ~ Implementing a Lake Ontario LaMP • Ill -" ~ Biodiversity Conservation Strategy v Ill~ ; April 2011 ): z Lake Ontario 002987_IE10_03-B3278 Implementing a Lake Ontario LaMP Biodiversity Conservation Strategy April 2011 April 2011 To our biodiversity conservation partners: The attached Lake Ontario Lakewide Management Plan (LaMP) report, Implementing a Lake Ontario LaMP Biodiversity Conservation Strategy, April 2011, is the result of years of stakeholder consultation, solicitation of expert opinions, and consideration of existing biodiversity conservation program goals and objectives. The results of this broad stakeholder consultation process were summarized in the report The Beautiful Lake, A Binational Biodiversity Strategy for Lake Ontario, April 2009, which identifies twenty-six shorelines and watersheds of greatest value to Lake Ontario’s biodiversity. The attached LaMP implementation strategy lists the key recommendations provided in The Beautiful Lake report to be formally adopted by the LaMP. The LaMP will work to promote these actions, report on progress, identify resource needs and recommend additional actions as necessary to conserve Lake Ontario's biodiversity. The key elements of the Lake Ontario LaMP’s Binational Biodiversity Conservation Strategy are: 1) the integration of action priorities into existing programs and “place-based” planning activities especially within key watersheds, an activity best done by local governments and organizations and; 2) regional coordination of lakewide scale biodiversity monitoring and restoration activities. Given the enormous amount of work needed to restore and protect Lake Ontario’s biodiversity, the LaMP recognizes that the key to success lies in our ability to build and foster cooperative partnerships throughout the Lake Ontario basin. To that end, we ask that you consider the strategies and key steps outlined in this report as you plan and undertake activities to restore and protect Lake Ontario’s biodiversity.
