A rugged, whitewater river flowing northward through deep canyons, the New River is among the oldest rivers on the continent. New River Gorge National River in West Virginia encompasses over 70,000 acres of land along the New River, is rich in cultural and natural history, and offers an abundance of scenic and recreational opportunities.
Denali is six million acres of wild land, bisected by one ribbon of road. Travelers along it see the relatively low-elevation taiga forest give way to high alpine tundra and snowy mountains, culminating in North America's tallest peak, 20,310' Denali. Wild animals large and small roam un-fenced lands, living as they have for ages. Solitude, tranquility and wilderness await.
DOINews: Recent Paper Assessed Risks For Adult Butterflies Exposed To Mosquito Control Pesticide Naled
USGS scientist Dr. Tim Bargar (USGS Southeast Ecological Science Center) recently published a new method to prospectively assess risks for adult butterflies exposed to the mosquito control pesticide naled. Prior to this paper, no published method existed for estimating adult butterfly exposure to a pesticide applied as an ultra-low volume spray. The paper's findings provide a guideline value for naled deposition that managers can use to minimize the risk of death for adult butterflies. Although there remains uncertainty about the relationship between application rates and deposition levels, the findings are still useful for making decisions about mosquito spraying. The article, Risk assessment for adult butterflies exposed to the mosquito control pesticide naled, was published in the journal Environmental Toxicology and Chemistry.
