‘No ship captain or shipping company wants to strike a whale’
Satellite data about whale movements and ocean conditions have helped scientists create monthly whale hotspot maps that could help avert collisions between ships and marine mammals.
Developed by researchers with NOAA Fisheries, Oregon State University and the University of Maryland, the WhaleWhatch program alerts ships where there may be an increased risk of encountering these endangered whales. NASA helped fund the project, which draws on ocean observations from NASA and NOAA satellites. Continue reading “Satellite mapping could help avert whale-ship crashes”→
Conservation activists won protection for the plants in 2013, when the U.S. Fish and Wildlife Service determined that 91 percent of Graham’s beardtongue populations and 100 percent of White River beardtongues were threatened by the impacts of oil and gas development. But a year later, the agency reversed course, claiming that a voluntary conservation agreement would mitigate those threats. Continue reading “Legal wrangling continues over rare oil patch plants”→
Oil and gas exploration would have widespread effects on marine mammals
Conservation advocates have long been saying that blasting the Gulf of Mexico with seismic airguns to find more oil and gas beneath the seafloor would result in unacceptable harm to marine mammals and other marine life, and a new draft environmental study by the Bureau of Ocean Energy Management seems to confirm those concerns.
The study was completed under the terms of a court-ordered settlement of a lawsuit brought by environmental groups. It shows that the blasting would have widespread impacts on marine life, including injuries to endangered sperm whales and Bryde’s whales. The draft report outlines possible mitigation measures, including closure areas where seismic blasting would be banned, and reductions in the amount of activity permissible each year.

A federal judge in Montana has once again ruled that the U.S. Fish and Wildlife Service violated the Endangered Species Act when it excluded Colorado from a critical habitat designation for threatened lynx. In the end, the rare cat may yet get some protected sanctuaries in the Colorado high county.
New study documents population declines in Great Basin
U.S. Geological Survey scientists have filled in another piece in the pika puzzle, finding that changes in distribution of populations of the tiny mammals are mainly influenced by climatic factors. The new study, published in The Journal of Mammalogy, helps show how global warming will affect the species.
Several previous research efforts have been inconclusive, and one study from Colorado suggests that pikas are holding their own in the highest reaches of the central and southern Rocky Mountains. But the new study, conducted in 2014 and 2015 at 910 sites, showed widespread reduction in pika range in three mountainous regions including the Great Basin, southern Utah and northeastern California.
‘Reducing immediate impacts is essential to tackling the biodiversity crisis’
About 75 percent of the world’s threatened species are at risk because of human impacts to their environment and unsustainable harvesting, according to a new study in the journal Nature.
“Addressing these old foes of overharvesting and agricultural activities are key to turning around the biodiversity extinction crisis” said lead author Sean Maxwell of the University of Queensland, “This must be at the forefront of the conservation agenda.”
Scientists from the University of Queensland, the Wildlife Conservation Society and the International Union for Conservation of Nature studied 8,688 species on the IUCN Red List. They found that 72 percent of species are imperiled by unsustainable harvesting. The production of food, fodder, fiber and fuel crops; livestock farming; aquaculture; and the cultivation of trees imperils another 62 percent. By comparison, 19 percent are considered threatened by climate change. Continue reading “New report IDs biggest global threats to wildlife”→
Continued illegal gill net fishing cited in push for ban on Mexican seafood
In what could be a last-ditch effort to save imperiled vaquita in the Gulf of California, conservation advocates are urging the Obama administration to launch economic sanctions against Mexico to halt that country’s trade in totoaba. According to the Center for Biological Diversity, the sanctions would be justified because Mexico is violating the Convention on International Trade in Endangered Species (CITES) by not enforcing the ban on totoaba trade.
