ANCHORAGE, Alaska — Due to climate change, some communities in rural Alaska and the Yukon Territory of Canada may face a future with fewer caribou according to new research published by the U.S. Geological Survey and the University of Alaska, Fairbanks in the recent issue of PLoS ONE. Scientists examined the future effects of fires on winter habitats of caribou herds and determined that wildfires will reduce the amount of winter habitat for caribou, thus caribou may need to shift their wintering grounds
Warming temperatures will increase the flammability of lichen-producing boreal forests, which are important winter habitat for caribou herds. Caribou serve as nutritional as well as cultural sustenance for certain communities. Caribou avoid burned areas in winter and the changes in their distribution can persist across multiple generations of hunters. Those who rely on caribou in fire-prone areas may therefore have fewer available as climate change increases the number and sizes of fires in the boreal forests.
“We project that the Porcupine caribou herd will lose 21% of winter habitat to fire by the end of this century, with the majority of this loss driven by increased flammability in spruce forests in the Yukon," said Dr. Dave Gustine, a Research Wildlife Biologist with the USGS and lead author of the study.
The study examines how increasing temperatures will influence flammability of boreal forest areas used by the Central Arctic and Porcupine caribou herds during winter. Understanding possible changes to forest flammability allows forecasting of future winter distributions of caribou that will impact subsistence harvest and land, wildlife and fire management programs.
Climate change is global in scope and scale; however, its impacts are sometimes most visible in remote locations of the planet. Like climate change itself, migratory animals such as caribou do not recognize international geo-political borders and the research needed to study the relationship between climate change and animals crosses many countries.
The potential changes in caribou distribution will affect communities that have a cultural and nutritional reliance on caribou. Arctic Village, Alaska and Old Crow Yukon Territory, are within the traditional boreal forest winter range of the Porcupine herd, while hunters from the Alaskan villages of Fort Yukon, Venetie and Chalkyitsik, travel north each year to harvest animals from this herd.
“Fires were less numerous and smaller in tundra habitats compared to spruce habitats and given the more likely climate trajectory, we projected that the Porcupine caribou herd, which winters primarily in the boreal forest, could be expected to experience a greater reduction in lichen-producing winter habitats than the Central Arctic herd that wintered primarily in the arctic tundra,” said Dr. Todd Brinkman a co-author of the study and member of the Scenarios Network for Alaska and Arctic Planning at the University of Alaska, Fairbanks.
Future work by the USGS and collaborators will examine how fire-driven changes to winter habitat and temperature-driven changes to spring and summer forages will influence the habitats of caribou across the Alaskan Arctic.

Insecticides similar to nicotine, known as neonicotinoids, were found commonly in streams throughout the Midwest, according to a new USGS study. This is the first broad-scale investigation of neonicotinoid insecticides in the Midwestern United States and one of the first conducted within the United States.
Effective in killing a broad range of insect pests, use of neonicotinoid insecticides has dramatically increased over the last decade across the United States, particularly in the Midwest. The use of clothianidin, one of the chemicals studied, on corn in Iowa alone has almost doubled between 2011 and 2013.
“Neonicotinoid insecticides are receiving increased attention by scientists as we explore the possible links between pesticides, nutrition, infectious disease, and other stress factors in the environment possibly associated with honeybee dieoffs.” said USGS scientist Kathryn Kuivila, the research team leader.
Neonicotinoid insecticides dissolve easily in water, but do not break down quickly in the environment. This means they are likely to be transported away in runoff from the fields where they were first applied to nearby surface water and groundwater bodies.
In all, nine rivers and streams, including the Mississippi and Missouri Rivers, were included in the study. The rivers studied drain most of Iowa, and parts of Minnesota, Montana, Nebraska, North Dakota, South Dakota, and Wisconsin. These states have the highest use of neonicotinoid insecticides in the Nation, and the chemicals were found in all nine rivers and streams.
Of the three most often found chemicals, clothianidin was the most commonly detected, showing up in 75 percent of the sites and at the highest concentration. Thiamethoxam was found at 47 percent of the sites, and imidacloprid was found at 23 percent. Two, acetamiprid and dinotefuran, were only found once, and the sixth, thiacloprid, was never detected.
Instead of being sprayed on growing or full-grown crops, neonicotinoids can be applied to the seed before planting. The use of treated seeds in the United States has increased to the point where most corn and soybeans planted in the United States have a seed treatment (i.e., coating), many of which include neonicotinoid insecticides.
“We noticed higher levels of these insecticides after rain storms during crop planting, which is similar to the spring flushing of herbicides that has been documented in Midwestern U.S. rivers and streams,” said USGS scientist Michelle Hladik, the report’s lead author. “In fact, the insecticides also were detected prior to their first use during the growing season, which indicates that they can persist from applications in prior years.”
One of the chemicals, imidacloprid, is known to be toxic to aquatic organisms at 10-100 nanograms per liter if the aquatic organisms are exposed to it for an extended period of time. Clothianidin and thiamethoxam behave similarly to imidacloprid, and are therefore anticipated to have similar effect levels. Maximum concentrations of clothianidin, thiamethoxam and imidacloprid measured in this study were 257, 185, and 42.7 nanograms per liter, respectively.
The U.S. Environmental Protection Agency has classified all detected neonicotinoids as not likely to be carcinogenic to humans.

Almost 10 months ago, heavy rains brought flooding, landslides and mudslides to several counties along Colorado’s Front Range. Since that time, nearly $449 million in grants, reimbursements, low-interest loans and insurance payments to individuals, businesses and communities has been approved by the State of Colorado, the Federal Emergency Management Agency (FEMA), the National Flood Insurance Program and the U.S. Small Business Administration (SBA).Language English
DENVER — Rebuilding after a disaster can present opportunities as well as challenges.
The challenges include getting the job done quickly and efficiently. The opportunities involve rebuilding stronger and better.
When it comes to repairing and rebuilding infrastructure damaged in last September’s floods, FEMA’s Stafford Act Section 406 can provide mitigation funds for risk-reduction improvements to roads, waterways, bridges, dams, buildings and other public structures already eligible for Public Assistance reimbursement.Language English
