Lead Ammunition Poisons Wildlife But Too Expensive To Change, Hunters Say

Read the full story from NPR.

Just before leaving office, the Obama administration banned the use of lead ammunition on federal land. Some hunters want President Trump to reverse the ban.

Can New DNA Science Help Keep Our Fish Safe?

Scientists are experimenting with species’ environmental DNA to find out how far and how fast it travels in streams. The technology is starting to revolutionize how we protect native animals.

New Maps Show How Our Consumption Affects Wildlife Thousands of Miles Away

Read the full story from Pacific Standard.

Global trade has made it easier to buy things. But our consumption habits often fuel threats to biodiversity — such as deforestation, overhunting, and overfishing — thousands of miles away.

Now, scientists have mapped how major consuming countries drive threats to endangered species elsewhere. Such maps could be useful for finding the most efficient ways to protect critical areas important for biodiversity, the researchers suggest in a new study published in Nature Ecology & Evolution.

Final EPA/USGS Technical Report: Protecting Aquatic Life from Effects of Hydrologic Alteration Documents

Download the document.

This report presents a literature review of natural flow and a description of the potential effects of flow alteration on aquatic life, as well as examples of water quality criteria that some states have developed to support natural flow and maintain healthy aquatic life. The report also describes a flexible technical and scientific framework that state water managers can consider if they are interested in developing narrative or numeric targets for flow that are protective of aquatic life.

This scientific and technical report is non-regulatory and does not affect or constrain state or tribal discretion.

Hydrologic alteration can include an increase or decrease in water volume, seasonal flow disruption, and dramatic variation in water temperature. Hydrologic alteration can affect aquatic species’ ability to spawn, gather nutrients from the stream system, access high-quality habitat, and more. Hydrologic alteration may be further exacerbated through climate change. Recent climate trends have included the change in frequency and duration of extreme weather events, such as droughts and floods, which can have an impact on flow and affect aquatic life. Maintaining flow targets may help increase a stream’s resilience to climate change by reducing or avoiding intensification of existing stressors.

What satellites can tell us about how animals will fare in a changing climate

Read the full story at Space Daily.

From the Arctic to the Mojave Desert, terrestrial and marine habitats are rapidly changing. These changes impact animals that are adapted to specific ecological niches, sometimes displacing them or reducing their numbers. From their privileged vantage point, satellites are particularly well-suited to observe habitat transformation and help scientists forecast impacts on the distribution, abundance and migration of animals.

Native prairie restoration fights invasive species and helps the endangered ones

Even prairie remnants as small as potted plants on an apartment balcony can help butterflies migrate.

Feds to consider renewed protections for bird species

Read the full story in The Hill.

Federal officials are formally considering whether to reinstate protections for the lesser prairie-chicken.

The Interior Department’s Fish and Wildlife Service (FWS) announced the decision Tuesday, reigniting a high-profile debate over Endangered Species Act protections. The protections pit environmental groups against oil companies who say protecting the bird would dramatically increase the costs of drilling within its range.
