Distribution and Abundance of Invasive Nonindigenous Plants and Rare Plants at Two Riverine National Parks in the Great Lakes Network
ISBN: 9781495279867 / Angielski / Miękka / 82 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. Invasion by non-indigenous plants is widely considered to be a primary threat to species diversity and ecosystem function. Ecosystem changes resulting from these invasions may negatively impact native plant communities as a whole, as well as rare and endangered species. This report explores existing reports on rare plant locations in Mississippi National River and Recreation Area (MISS), and Saint Croix National Scenic Riverway (SACN). No rare plant surveys were performed for this study. In addition, we performed invasive plant surveys on several species considered "target" species of concern...

Management Guide to Ecosystem Restoration Treatments: Whitebark Pine Forests of the Northern Rocky Mountains, U.S.A.
ISBN: 9781482034400 / Angielski / Miękka / 144 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. Whitebark pine is declining across much of its range in North America because of the combined effects of mountain pine beetle epidemics, fire exclusion policies, and widespread exotic blister rust infections. This management guide summarizes the extensive data collected at whitebark pine treatment sites for three periods: (1) pre-treatment, (2) 1 year post-treatment, and (3) 5 years post-treatment (one site has a 10 year post-treatment measurement). Study results are organized here so that managers can identify possible effects of a treatment at their own site by matching it to the most...

Wildlife Strikes to Civil Aircraft in the United States 1990-2012
ISBN: 9781495459108 / Angielski / Miękka / 116 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. In 2012, the FAA and USDA continued to make great progress with its multifaceted approach for mitigating wildlife strikes. The FAA ensured that 100 percent of Part 139 airports have completed a Wildlife Hazard Assessment (WHA), are in the process of conducting a WHA, or have taken a Federal grant to conduct a WHA. Strike reporting continued to increase, especially with General Aviation (GA) aircraft, which increased strike reporting by 11 percent between 2011 and 2012. The FAA implemented three performance metrics to monitor strike reporting trends and GA wildlife mitigation. The performance...

Assessment of Rangeland Ecosystem Conditions, Salt Creek Watershed and Dugout Ranch, Southeastern Utah
ISBN: 9781495960994 / Angielski / Miękka / 64 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. Increasingly, dry rangelands are being valued for multiple services beyond their traditional value as a forage production system. Additional ecosystem services include the potential to store carbon in the soil and plant biomass. In addition, dust emissions from rangelands might be considered an ecosystem detriment, the opposite of an ecosystem service. Dust emitted may have far-reaching impacts, for example, reduction of local air quality, as well as altering regional water supplies through effects on snowpack. Using an extensive rangeland monitoring dataset in the greater Canyonlands region...

Protocol for Monitoring Aquatic Invertebrates of Small Streams in the Heartland Inventory & Monitoring Network
ISBN: 9781492355090 / Angielski / Miękka / 144 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych.
