Filtering agricultural runoff with constructed and restored wetlands

wetland

From the California Institute for Rural Studies: “Non-point source pollution (NPS) is a global problem affecting the safety of our drinking water supply and aquatic habitats. According to the 2000 National Water Quality Inventory, agriculturally derived NPS is the leading cause of water quality degradation in surface waters. Pollutants originating from agricultural runoff include sediment, nutrients (N and P), pesticides, […]

Reducing entrainment risk for juvenile green sturgeon

juvenile green sturgeon

From the FishBio blog: “Water diversions make outmigration a risky business for juvenile green sturgeon in the Sacramento River, but new research points to solutions for reducing this threat. In a previous Fish Report, we described a study conducted by researchers from the University of California, Davis, who discovered that juvenile green sturgeon were more likely to be entrained than […]

‘Refuge’ for the endangered Delta smelt — newly funded

?????????????????????????????????????????????????????????????????????????????????

From UC Davis: “Delta smelt are hard to find. Federally listed as threatened in 1993 and as endangered under the California Endangered Species Act in 2009, they are an iconic species for water issues in the state. But there’s one place where the fish can be found by the thousands — the Fish Conservation and Culture Laboratory at the University […]

Déjà Vu: El Niño Take Two

DejaVu_subsurface_temps_610

From the ENSO blog: “Here we are—in March 2015—and we’ve got…  above-average temperatures in the subsurface equatorial Pacific, westerly wind anomalies near the surface across the western tropical Pacific Ocean, and El Niño favored through the Northern Hemisphere Summer with a 50-60% chance.  Unbelievably, it was exactly last year at this time (March 2014) when we were watching the progress […]

Increased sensitivity to climate change in disturbed ecosystems

Heathland

From Science Daily: “Undisturbed ecosystems can be resistant to changing climatic conditions, but this resistance is reduced when ecosystems are subject to natural or anthropogenic disturbances. Plants are particularly sensitive to climatic changes in early life stages and even small climatic changes can cause vegetation shifts when ecosystems are disturbed by fires, insect outbreaks or other disturbances.  This is the […]

CRAM logo

The California Rapid Assessment Method for wetlands and riparian areas (CRAM) has been developed as a tool for standardized and cost-effective assessment of wetland condition. This training session will provide the skills necessary to consistently conduct accurate assessments of wetlands using CRAM, and will provide guidance on the use of CRAM for ambient and project assessment and monitoring. The session […]

Rethinking wetland restoration: Smaller wetlands more valuable than previously thought

potholes

From Science Daily: “Most efforts to protect and restore wetlands mistakenly focus on preserving only total wetland area, with no consideration of ecosystem services provided by different wetland types, according to a new study from the University of Waterloo.  The study, published in the peer-reviewed journal Ecological Applications last month, shows wetland loss follows a strong pattern, with smaller, isolated […]
