[Feb-10-2014] PSW’s Institute of Pacific Islands Forestry help restore ancient Hawaiian fishpond - Research station staff helped to restore an ancient Hawaiian Kīholo fishpond, which was once a vital food source and critical habitat for rare invertebrate species endemic to the Hawaiian Islands. Staff cleared debris from the pool perimeter to reduce nutrient loading caused by overhanging vegetation, as well as removed weeds and tended to native plants within a fenced unit that will be used as a nursery area for future restoration activities.
[Jan-21-2014] Integrating vegetation into sustainable transportation planning may benefit public health - In recent years, the health of people living, working, or going to school near roads with high traffic volume has been a rising national concern. Studies conducted in the United States and throughout the world have shown that air pollution levels are especially elevated near high-volume roadways. A multidisciplinary group of researchers, planners and policymakers recently gathered in Sacramento, Calif. to discuss roadside vegetation as a viable option for mitigating these adverse health impacts from air pollution. The group combined their key concerns and findings for an article in TR News magazine. [Read the full news release at www.fs.fed.us/psw/news/2014/20140121_sustainable_transportation.shtml]
[Jan-06-2014]Seventy-nine years of monitoring demonstrates dramatic forest change - Long-term changes to forests affect biodiversity and how future fires burn. A team of scientists led by Research Ecologist Dr. Eric Knapp, from the U.S. Forest Service’s Pacific Southwest Research Station, found dramatic differences in forests today compared to historic conditions prior to logging and fire suppression.

[25-Nov-2013] Lowering stand density reduces mortality of ponderosa pine stands - As trees grow larger in even-aged stands, competition develops among them. Competition weakens trees, as they contend for soil moisture, nutrients, and sunlight. Competition also increases trees’ risk to bark beetles and diseases, and subsequently leads to a buildup of dead fuels. A recent study, led by Dr. Jianwei Zhang, research forester at the U.S. Forest Service's Pacific Southwest Research Station, considered if the onset of this risk could be determined. The study, which appears in the Canadian Journal of Forest Research, also considered if the relationship between density and mortality varies with site quality as ponderosa pine stands developed.

[26-Jun-2013] Students help with research on the Kings River Experimental Watersheds - Six students from Sierra High School in Prather, Calif. spent three days conducting research on the Kings River Experimental Watersheds. They helped install resin-bead lysimeters (water collectors) that measure nitrogen deposition and fluxes for a year across an entire watershed. This work helps PSW researchers evaluate the impact of air pollution on the forest and soils and understand how forests are using nutrients. The students also learned about watershed condition, air pollution and Yosemite toad monitoring. This is the second consecutive year that staff from PSW-Fresno has hosted students through the school's Environmental Adventures program, a vocational training for environmental sciences which was funded by the U.S. Forest Service.

[08-Mar-2013] Celebrating Women's History Month - As the oldest of 11 children, Barbara C. Weber is accustomed to being the "first." With top family ranking comes responsibility, and Weber had plenty of it. Growing up on her family's 160-acre dairy farm in Bloomington, Wis., Weber, along with her siblings, helped clean the barn, pick up eggs, herd the cows and take care of the sheep, pigs and chickens. Taking a break from her chores, Weber enjoyed exploring the critters—snails, turtles and fish—that lived in the pond and creek on the farm's back pasture. Her innate curiosity and connection to nature led to her love of science. [Read more at the FS national website.]
[07-Mar-2013] All trees are not equal: Tips for tree selection - California Arbor Week, March 7-14, is a great time to think about all of the benefits that trees bring to us and our communities. Trees filter harmful pollutants from the air, mitigate climate change by storing carbon dioxide, reduce energy costs by providing shade, and lower greenhouse gas emissions. So, consider planting a tree on your property, or in your community. Pacific Southwest Station research forester Dr. Greg McPherson provides some helpful tips on how to select and plant the tree that’s best for you.

Urban Releaf, an Oakland-based urban forestry/environmental non-profit organization committed to the revitalization of communities through tree planting, garden projects and environmental education, will use the funds to continue work on these and other projects.
[09-Jul-2012] New Study Shows that Fuel Reduction Treatments Pose Little Risk to Forest Ecology A recent paper in Bioscience co-authored by USDA Forest Service Pacific Southwest Research Station researcher Dr. Chris Fettig and scientists from six universities in the U.S. and Australia have shown that forest fuels treatments such as prescribed fire and mechanical thinning which are now commonly used to treat stands in order to increase their resiliency to wildfires, can, indeed, be implemented with few unintended consequences. The scientists analyzed a broad spectrum of ecological markers, detailing the effects of fuel-reduction treatments on vegetation, soils, wildlife, bark beetles and carbon sequestration, while relying heavily on data from the U.S. Fire and Fire Surrogates Study, in addition to other research.

[11-Aug-2010] Carbon costs and benefits of fuel treatment - The amount of carbon stored in our forest ecosystem, mainly in living biomass and soil, is also to a lesser extent also in dead wood and litter. Understory thinning and prescribed fires reduce carbon stocks and produce emissions, but continued tree growth re-sequesters that carbon in approximately 15 years. Learn about the several carbon costs that should be considered when conducting prescribed burning or thinning to reduce tree density and surface fuel loads:
[29-Jul-2010] Prescribed Burning Helps Managers Avoid Soil Damage - In a study funded by the Joint Fire Science Program and the National Fire Plan, soil heating was measured during a series of experimental burns that compared several soil types and moisture contents. The study revealed that soil-moisture content greater than 20 percent by volume effectively quenched the heat pulse in a wide variety of soils. From these findings, a predictive model was presented that allows fire managers to identify fuel load and moisture conditions to avoid soil damage during burning.

[09-Mar-2010] There's No Place Like Home; Sierra Nevada yellow-legged frogs are further imperiled by their strong site fidelity to degraded sites - researchers Kathleen Matthews and Haiganoush Preisler found that site fidelity, the tendency to return to previously occupied habitats, is strong in the Sierra Nevada yellow-legged frog. The research showed how cumulative effects of a changing climate and introduced non-native trout are negatively impacting the habitat of a species already extirpated from 90% of its historic localities, and will further stress frogs with strong site fidelity. Low snowpack levels causing lake drying and predation by introduced non-native trout is hampering the breeding success of this imperiled frog. A recently published study in the Canadian Journal of Fisheries and Aquatic Sciences titled "Site fidelity of the declining amphibian Rana sierra (Sierra Nevada yellow-legged frog)" underscores the need to incorporate the site fidelity habits of this frog while designing restoration strategies for its continued existence.

[09-Nov-2009] Researchers model carbon storage and emissions after different fuels treatments: PSW scientist, Malcolm North, and collaborators sought to better understand how to manage forests with frequent fire regimes to maximize carbon sequestration and minimize emissions. They used a computer model and field data to study how different fuel reduction treatments, including thinning and/or prescribed burning, affect the amount of carbon stored and released in Sierra Nevada mixed-conifer forests with and without wildfire. The field data and model focused on tree-based carbon and quantified total carbon storage and emissions immediately following different fuels treatments and projected over a century. They concluded that a low-density forest dominated by large fire-resistant pines may be a desired stand structure for stabilizing tree-based carbon stocks in fire prone areas. Learn more ...
