A court-ordered settlement will protect marine mammals.
Seafood imports to U.S. must meet high marine mammal protection standards
FRISCO — In what conservation advocates are calling a landmark settlement, the U.S. government this week agreed to implement a long-ignored provision of the Marine Mammal Protection Act that will require foreign fisheries to meet the same standards required of U.S. fishermen or be denied import privileges. Continue reading

Duke University researchers say community based conservation measures also needed
FRISCO —Hawaii’s spinner dolphins need federal regulations limiting human access to resting areas, but that alone won’t be enough to help them survive in the long run. Along with any new federal rules, resource managers will also have to work to develop local community-based conservation measures, which can be tailored to how individual bays are used, according to new research by Duke University.
Federal biologists estimate there are about 3,000 spinner dolphins around Hawaii, where hundreds of thousands of tourists pay for up-close encounters with the animals, swimming with them in shallow bays the dolphins use as safe havens for daytime rest. But as the number of tours increases, so do the pressures they place on the resting dolphins. Continue reading

Refuge managers seek to balance protection of marine mammals with demand for public access at Three Sisters Springs
FRISCO — The U.S. Fish and Wildlife Service says a careful management plan at a freshwater spring in Florida can help protect manatees and ensure public access to the popular Three Sisters Springs recreation area.
The agency this week started taking input on a draft environmental assessment for management actions to protect manatees and still allow public access at Three Sisters Springs during the winter season. Continue reading

Pollution, boat strikes contribute to decline of Balearic population
FRISCO — Growing tourism, fishing, pollution and general marine traffic is threatening a small population of bottlenose dolphins living in coastal waters off the Pityusic Islands in the Mediterranean Sea, according to a study led by University of Barcelona researchers.
The biologists said they were able for the first time to get an accurate population count of the dolphins during spring and summer, crucial seasons for the marine mammals. Continue reading

Feds to decide on protection by 2016
FRISCO — Under a court-sanctioned settlement, federal biologists say they will shape a new critical habitat proposal for North Atlantic right whales by early 2016.
Each year most of the 500 North Atlantic right whales remaining on Earth migrate from their feeding and breeding grounds off the U.S. Northeast to their nursery areas off the Southeast. Continue reading

‘It is essential to identify where whales, dolphins and other species occur to help avoid adverse impacts and to continue to monitor their response to the construction and operation of wind turbines’
Offshore wind turbines could provide most of the power for North American cities.
FRISCO — Many of the conflicts between energy development and wildlife protection developed because there wasn’t enough upfront planning. Researchers with the University of Maryland say similar issues relating to offshore wind energy can be minimized with early monitoring.
“As the number and size of offshore wind developments increases, there is a growing need to consider the consequences and cumulative impacts of these activities on marine species,” said Helen Bailey, lead author and research assistant professor at the University of Maryland Center for Environmental Science’s Chesapeake Biological Laboratory.
“It is essential to identify where whales, dolphins and other species occur to help avoid adverse impacts and to continue to monitor their response to the construction and operation of wind turbines,” Bailey said. Continue reading

Can sea otters bounce back from the brink?
Population along California coast hovering near targeted recovery level
FRISCO — Sea otters are making a slow and steady comeback along the Central California coast, with the species’ population nearing a level that could earn them the distinction of being taken off the endangered species list.
In the latest official population estimate released last week, federal scientists said there were just under 3,000 southern sea otters living along the Central California coast, based on a population index used since the 1980s. That’s up slightly from 2013 and just shy of the 3,090 threshold set by the U.S. Fish and Wildlife Service as a recovery benchmark. Continue reading
