Round 5 in fight over highway widening through redwood trees

It’s unclear why CDOT persists in efforts to start a highway project that could pose a threat to redwood forests in Humboldt County, California. @bberwyn photo.

Activists stand their ground against destruction of trees

Staff Report

A contentious proposal to widen U.S. Highway 101 through redwood groves in Humboldt County, California is once again facing a court challenge from conservation groups and local residents, who say the state transportation agency failed to adequately review and disclose environmental impacts.

This is the fifth time CDOT has been sued over the project that could needlessly damage or destroy thousand-year-old redwood trees in California’s iconic Richardson Grove State Park. Some of the trees in the park are trees up to 3,000 years old, 18 feet in diameter and 300 feet tall. Caltrans has pursued this project solely to incrementally improve passage for oversized commercial trucks, and continues to rely on inadequate environmental review.

Can ‘supersites’ anchor coral reef protection efforts?

Study says 90 percent of all predatory fish species have been lost from Caribbean coral reefs

Staff Report

Not all Caribbean reefs are created equal, say researchers with the  University of North Carolina at Chapel Hill, who recently identified reef areas they are calling “supersites”that could help restore populations of predatory fish needed maintain an ecological balance.

That’s the good news. The bad news is their study also shows that up to 90 percent of predatory fish are gone from Caribbean coral reefs. The research suggests that these supersites should be prioritized for protection and could serve as regional models showcasing the value of biodiversity for tourism and other uses.

Study says road threat to carnivores is underestimated globally

Findings to help guide conservation strategies

Staff Report

The threat of roads to carnivore species around the world has been seriously underestimated, according to a new study that looked at the issue on a global scale.

After looking at 232 carnivore species around the world (out of a total of about. 270 existing species) and assessing how severely these are affected by roads cut through their habitat, the researchers concluded that some rare species are even at risk in areas with low road densities. The study, published in the journal Global Ecology and Biogeography, calculated natural mortality rates, reproduction and carnivore movement patterns, determining the maximum density of roads that a species can cope with.

Federal judge backs USFWS decision to end a ‘no otter’ zone in Southern California

Staff Report

California sea otters may have a better chance of expanding south along the coast after a federal judge last week backed a U.S. Fish and Wildlife Service decision to end a program that removed otters from areas south of Point Conception.

The “no-otter zone” was established by Congress in 1986 during the early days of political meddling with the Endangered Species Act, in response to complaints from fishermen that moving otters to a new location could interfere with their fishing activities.

FRISCO — It’s not always easy to gather good scientific data, especially in an era when political ideology drives policy, resulting in budget cuts that hamper government agencies.

That’s where citizen science can help, and Trout Unlimited wants anglers around the country to help record evidence of their trout catches both photographically and via mapping coordinates with the relaunch of TroutBlitz.

TU’s science team uses the data collected from anglers to learn more about native trout water, non-native trout proliferation and the health of entire watersheds. Continue reading “Anglers invited to join citizen science effort”

Feds promise $50 million for Western water conservation

Smart water management and conservation can help reduce drought pressure in the West

Staff Report

FRISCO — Efforts to conserve water in the drought-stricken Colorado River Basin and across the West got a major boost from the Obama administration this week. Federal resource managers this week announced a $50 million investment to  improve water efficiency and conservation in California and 11 other western states.

Scientists tout adaptive management approach to sage-grouse conservation

Staff Report

FRISCO — When it comes to greater sage-grouse nesting areas, no disturbance is best, but carefully planned mitigation measures can help boost nest survival.

Minimizing disturbance to sagebrush is important, and the single biggest factor found to boost nest survival is locating wastewater treatment facilities away from drilling sites, scientists said last week, releasing results of a multi-year study in Wyoming’s Powder River Basin.
