  • Contemporary Status, Distribution, and Trends of Mixedwoods in the Northern United States1 Lance A
    881 ARTICLE Contemporary status, distribution, and trends of mixedwoods in the northern United States1 Lance A. Vickers, Benjamin O. Knapp, John M. Kabrick, Laura S. Kenefic, Anthony W. D’Amato, Christel C. Kern, David A. MacLean, Patricia Raymond, Kenneth L. Clark, Daniel C. Dey, and Nicole S. Rogers Abstract: As interest in managing and maintaining mixedwood forests in the northern United States (US) grows, so does the importance of understanding their abundance and distribution. We analyzed Forest Inventory and Analysis data for insights into mixedwood forests spanning 24 northern US states from Maine south to Maryland and westward to Kansas and North Dakota. Mixedwoods, i.e., forests with both hardwoods and softwoods present but neither exceeding 75%–80% of composition, comprise more than 19 million hectares and more than one-quarter of the northern US forest. They are most common in the Adirondack – New England, Laurentian, and Northeast ecological provinces but also occur elsewhere in hardwood-dominated ecological provinces. These mixtures are common even within forest types nominally categorized as either hardwood or softwood. The most common hardwoods within those mixtures were species of Quercus and Acer,and the most common softwoods were species of Pinus, Tsuga,andJuniperus. Although mixedwoods exhibited stability in total area during our analysis period, hardwood saplings were prominent, suggesting widespread potential for eventual shifts to hardwood dominance in the absence of disturbances that favor regeneration of the softwood component. Our analyses sug- gest that while most mixedwood plots remained mixedwoods, harvesting commonly shifts mixedwoods to either hard- wood- or softwood-dominated cover types, but more specific information is needed to understand the causes of these shifts.

  • FAQ: HR 799 & S. 403: North Country National Scenic Trail Route Adjustment
    FAQ: HR 799 & S. 403: North Country National Scenic Trail Route Adjustment Act Exactly what does HR 799/S. 403 call for? These bills simply amend the National Trails System Act (16 U.S.C. 1244(a)(8)) by: (1) Substituting new language delineating the North Country National Scenic Trail’s total length (from 3200 to 4600 miles); (2) Re-defining the eastern terminus as the Appalachian National Scenic Trail in Vermont; and (3) Substituting a new map reference for the original, showing the Minnesota Arrowhead and the eastern terminus extension. So what does this accomplish? H.R. 799/S. 403 completes the original vision for the North Country National Scenic Trail (NCNST) by extending the eastern terminus to link with the Appalachian Trail in Vermont. And, this legislation legitimizes the de-facto route of the NCNST in Minnesota since 2005, with the formal inclusion of Minnesota’s Superior Hiking, Border Route and Kekekabic Trails as officially part of the North Country National Scenic Trail (NCNST). Wait--going from 3200 to 4600 miles sounds like a lot more than that! The original 1980 authorizing legislation contains the language “a trail of approximately 3200 miles.” This was clearly an estimate, since almost none of the NCNST had been built when the 1970’s feasibility studies estimated its length. Since then much of the NCNST has been constructed and the route identified; the trail is on the ground and we have more sophisticated tools for measuring it. As it turns out, in order to carry out Congress’ intent for the original NCNST the actual mileage is closer to 4100 miles, even without the Minnesota Arrowhead or the eastern terminus extension into Vermont (which add another 500 miles).

  • Great Lakes Shipping Study
    UNCLASSIFIED Great Lakes Shipping Study This page intentionally left blank. National Protection and Programs Directorate Integrated Analysis Task Force Homeland Infrastructure Threat and Risk Analysis Center January 13, 2014 UNCLASSIFIED Executive Summary The Great Lakes St. Lawrence Seaway (GLSLS) system is a vast, interconnected series of navigable waterways, with intersecting modes of transportation and landscapes. The enormity and importance of the GLSLS system cannot be overstated as the region is critically dependent upon it; therefore, it is vital to understand the nature of the system, the industries that rely upon it, its economic impact, and major commodities that flow through the GLSLS. This study provides an overview of the GLSLS system, focusing on geography, system infrastructure, economic and employment data derived from the GLSLS, and detailed analysis of three key commodities: iron ore, steel, and refined petroleum products. The GLSLS, which borders eight states and spans 2,300 miles, comprises Lake Superior, Lakes Michigan and Huron, Lake Erie, Montreal-Lake Ontario, and the Saint Lawrence Seaway, as well as the channels that connect these navigable sections. U.S. and Canadian companies and industries rely on the GLSLS for low-cost, long-distance transportation of raw materials and finished goods. In 2010, U.S. and Canadian companies that depend on the GLSLS for moving cargo reported revenues of over $30 billion, more than half of which was generated in the United States. The GLSLS is also responsible for the creation of hundreds of thousands of jobs, providing direct employment for mariners, many types of port employees, and support positions within the companies, as well as creating indirect jobs that result from the spending power of the previously mentioned workers.

  • Arctic Grayling
    Arctic Grayling For most anglers in America, the Arctic grayling (Thymallus arcticus (Pallus)) is a rare freshwater game fish symbolic of the clear, cold streams of the northern wilderness. Grayling occur throughout the arctic as far west as the Kara River in Russia and east to the western shores of Hudson Bay in Canada. Once as common as far south as Michigan and Montana, the Arctic grayling has almost disappeared from the northern United States because of overfishing, competition from introduced species, and habitat loss. General description: The Arctic grayling is an elegantly formed cousin of the trout. With its sail-like dorsal fin dotted with large iridescent red or purple spots, the grayling is one of the most unusual and beautiful fish of Alaska. Grayling are generally dark on the back and have iridescent gray sides. They have varying numbers of black spots scattered along the anterior portion of both sides. The adipose, caudal (tail), pectoral, and anal fins are gray and the pelvic fins are often marked with pink to orange stripes. Life history: Grayling have evolved many strategies to meet the needs of life in what are often harsh and uncertain environments. Grayling can be highly migratory, using different streams for spawning, juvenile rearing, summer feeding, and overwintering. Or, in other areas, they can complete their entire life without leaving a short section of stream or lake. Winter generally finds grayling in lakes or the deeper pools of medium-sized rivers such as the Chena and Gulkana, or in large glacial rivers like the Tanana, Susitna, and Yukon.

    University of New Hampshire CARSEY RESEARCH Carsey School of Public Policy National Issue Brief #138 Winter 2018 Population, Greenspace, and Development Conversion Patterns in the Great Lakes Region Mark J. Ducey, Kenneth M. Johnson, Ethan P. Belair, and Barbara D. Cook n ongoing concern in both urban and rural America is the tradeoff between residential and commercial development and the conservation Aof forestland, shrublands, and grasslands, commonly referred to as greenspace. As communities develop, adding schools, housing, infrastructure, and the com- mercial space needed for an expanding population and economy, greenspace remains critical because it contrib- utes to air and water purification, storm abatement, and enhanced human health and quality of life. The tension between development and maintaining greenspace is greatest where human populations are densely settled and expanding, and the concern is of particular relevance because the transformation tends to be permanent— developed land rarely reverts to greenspace. FIGURE 1. PERCENT GREENSPACE, 2001 This brief contributes to a better understanding of the linkages between demographic and land-cover change and provides facts that can inform policy aimed at bal- ancing development and greenspace conservation. Greenspace and Development in the Great Lakes Region The research summarized here1 combines demo- graphic, land-cover, and other spatial data to estimate the incidence and extent of conversion from greens- pace to development in the Great Lakes states (Illinois, Indiana, Michigan, Minnesota, Ohio, and Wisconsin). Greenspace is abundant in the Great Lakes region (Figure 1), an area that contains 9 percent of the nation’s land area and 16 percent of its population. Most of this population (81 percent) resides in metropolitan areas, but most of the land area is rural (66 percent).
