XXVIII No. 1 APRIL 2018 Changes to Migratory Bird Treaty Act weaken bird protections The Migratory Bird Treaty Act (MBTA), signed into law in 1918, is among the oldest and most effective wildlife protection laws on the books. When Congress passed the MBTA in 1918, it codified a treaty already signed with Canada, then part of Great Britain. The Treaty was in response to the serious overharvest of numerous bird species that had resulted in extinction in a few instances and near extinction in some species. Since 1918, the MBTA has broadened its international scope through treaties with Mexico, Japan, and Russia. The MBTA is credited with saving numerous species from extinction, including Trumpeter Swans. It continues to protect nearly all native birds in the U.S. covering more than 1,000 species, including Trumpeter Swans. The Department of Interior made significant changes to the Legislation in Congress (HR 4239), and a new interpretation interpretation of the century-old Migratory Bird Treaty Act. Photo by Margaret Smith of the law by the Administration, would end the ability to hold industries accountable for bird deaths. Industries would only be held accountable if their intention or purpose was to harm birds through their activities. This rolls back decades of bipartisan support and interpretation of the MBTA. It also removes industry incentives to prevent bird deaths and its associated penalties.

On April 30, 1803 France and the United States signed the Louisiana Purchase Treaty, causing the Louisiana Territory to transfer from French to United States control for the price of fifteen million dollars.1 The territorial acquisition was agreed upon by Napoleon Bonaparte, First Consul of the Republic of France, and Robert R. Livingston and James Monroe, both of whom were acting on behalf of the United States. Monroe and Livingston only negotiated for New Orleans and the mouth of the Mississippi, but Napoleon in regard to the territory said “I renounce Louisiana.

Higher status scores denote taxa with known declining trends. Status scores range from -20 (increasing) to 20 (decreasing). Score Population Trend in Alaska (-10 to 10) 2 Trumpeter swans were nearly driven to extinction in the early 1900s due to overhunting. They have recovered since then, and in Alaska have exhibited an average annual increase of +5.3% per year from 1968 to 2015 (i.e. since USFWS surveys began; Groves 2017). This growth rate has slowed in recent decades and the population appears to have stabilized since 2005 (Groves 2017; D. Groves, pers. comm.). Distribution Trend in Alaska (-10 to 10) -10 Over the past 50 years, trumpeter swans have expanded their distribution, both within the core and the peripheries of their Alaskan range (Conant et al. 2002). The population now occupies much of the suitable habitat within Alaska's boreal forest and appears to be reaching carrying capacity in some parts of the state (Groves 2017). Further significant expansion within their core breeding range is unlikely; however, the population has continued to expand into peripheral boreal-tundra ecotone habitat (Bryant et al.

  • Yellowstone: an Overview No Matter How Many Times One May Visit Yellowstone National Park, the Scenery of This Place Is Always New and Different
    Yellowstone: An Overview No matter how many times one may visit Yellowstone National Park, the scenery of this place is always new and different. My last photo program of Yellowstone was in 1998. That program can be found on acuri.net ‐ USA ‐ Wyoming (see in sources). This photo program series was taken between August and September 2019. There are five entrances to the park. The only two entrances that are open year‐round are North and Northeast. The other entrances are open to over‐the‐snow vehicles. They are closed to wheeled vehicles from November through mid‐April. Fees into the park are based on various categories. It covers 3,472 square miles and was established on March 1, 1872. Ninety‐six percent of the park is in Wyoming, three percent in Montana and one percent in Idaho. This photo program series on Yellowstone National Park includes nine subject titles. They are Artist Point, Canyon Visitor Education Center, Lamar Valley, Lake Hotel, Mammoth Hot Springs, Midway Geyser Basin, Norris Geyser Basin and Old Faithful. How Yellowstone got its name: "The park is located at the headwaters of the Yellowstone River, from which it takes its name. In the eighteenth century, French Trappers named the river "Roche Jaune," which is probably a translation of the Minnetaree name "Mi tsi a‐da‐zi" (Rock Yellow River). Later, American trappers rendered the French name in English as "Yellow Stone." Although it is commonly believed that the river was named for the yellow rocks seen in the Grand Canyon of the Yellowstone, the Native American name source is not clear." <nps.gov> Famous names and topics to further your learning more about Yellowstone are: "Tribal oral histories indicate more extensive use during the Little Ice Age.

  • Reader's Guide to the Mountain Men of the American West
    Reader©s Guide to the Mountain Men of the American West Antoine Clement, by Alfred Jacob Miller Compiled by Stuart Wier October 25, 2010 This is a guide to the best books about the mountain men of the American west which I know about. Anyone can find a book here to suit them: casual readers, students, enthusiasts, reenactors, and historians. I include a few less distinguished books, too, when they are the only thing about a topic. For some fifteen years -- roughly speaking, 1823 to 1838 and beyond -- the western U.S. was the domain of the mountain men, fur trappers who spent years traveling and living in the wilderness. Long before wagon trains, settlers, gold rushes, cavalry, Indian wars, cowboys, wild west towns, or railroads, mountain men were the first from the U.S. to see the Rocky Mountains and the lands from the plains to the Pacific. Their life was highly free and adventuresome, and often dangerous and short, lived in a shining wilderness. Where to begin? Many books, many choices. For a readable and short introduction try Give Your Heart to the Hawks by Winfred Blevins. For detailed histories try A Life Wild and Perilous by Robert M. Utley or the classic history Across the Wide Missouri by Bernard DeVoto. Or try some of the best biographies, such as Westering Man The Life of Joseph Walker by Bil Gilbert and Jedediah Smith and the Opening of the West by Dale L. Morgan. For adventures or "camp fire tales" try the personal journals and narratives written by some of the mountain men themselves.
