A new study uses airborne technology to track changes in Big Island tropical forests, revealing how climate and invasive species affect carbon stocks. The research finds that fast-growing invaders decrease biomass levels, while slower-growing species increase biomass stocks.
Three Palauans, Uelbil Puanani Michael, Omekrael Sadang, and Sheldon Siksei, have been selected as interns in the US Forest Service's Professional Internships in Pacific Terrestrial Island Ecosystem Management program. They will work on forestry projects in their home islands and later implement focus projects with mentors.
The US Forest Service has selected two Pohnpeian students, Fa'afo'i Tony Maugalei and John Ah Sue, as part of its Professional Internships in Pacific Terrestrial Island Ecosystem Management program. The program aims to recruit and train the next generation of forestry professionals in the Pacific Islands.
Three Kosraeans, Maximilian Nithan, Jacob Sanney, and Rickson Johnithan, have been selected as interns in the US Forest Service's Professional Internships program. They will address watershed management issues and implement focus projects to improve forestry practices in their communities.
Two Samoan students, Fa'afo'i Tony Maugalei and John Ah Sue, have been selected as part of the US Forest Service's Professional Internships in Pacific Terrestrial Island Ecosystem Management program. They will develop and evaluate an agroforestry project on private lands to demonstrate economically viable forest management methods.
A 10-year study found that climate change limits the amphibian's breeding habitat in high-elevation lakes, leading to population decline. The Sierra Nevada Yellow-legged frog relies on two to four years of permanent water for development, making repeated tadpole mortality from lake drying a critical threat.
The Tree Carbon Calculator provides quantifiable incentives for tree planting and stewardship projects. It calculates the dry weight of biomass that would be obtained if a tree were removed, offering a valuable resource for urban forestry efforts.
A new book provides a comprehensive overview of air pollution research, focusing on wildland fires' impact on humans and the environment. The 686-page book includes 26 research papers by 85 experts, covering regional perspectives and current tools for managing forests affected by fire and climate change.
Lichens can reveal nitrogen air pollution's impact on Sierra Nevada and San Bernardino mountain ecosystems. Protecting lichens safeguards less sensitive species.
A US Forest Service study reveals that most homeowners in fire-prone areas have taken steps to protect their homes, but barriers such as financial constraints and physical limitations persist. The study also found that residents are concerned about fires and think they know how to reduce the threat.
The report highlights the importance of real-time information on fire location, size, and movement for effective communication during evacuations. Fire managers can consider providing detailed information about fire regulations to improve visitor perceptions of recreation activities.
A team of 23 scientists examined the effects of controlled burns and forest thinning on western Ponderosa pine ecosystems. They found that tree growth increased after thinning, but with a single canopy layer, while controlled burns had little impact on large trees but harmed smaller ones.
A study by the USDA Forest Service found that Indianapolis street trees annually intercept 318.9 million gallons of rainfall, valued at $1.98 million, and reduce electricity use by over 6,447 megawatt hours, worth $432,000. The trees also improve air quality and increase property values.
Preliminary results from DNA analysis of wolverine scat samples collected on the Tahoe National Forest do not match those of historic California wolverine populations. The animal is identified as a male wolverine that does not genetically match populations in Washington or Southern Sierra Nevada.
Researchers and volunteers have intensified the search for wolverine evidence in the Tahoe National Forest after a recent photograph was captured. Genetic analysis of scat and hair samples is underway to determine the animal's origin and sex, with potential implications for conservation efforts.
USDA scientists have developed a method to grow high-value koa trees faster while maintaining biodiversity, carbon sequestration, and scenic beauty in native Hawaiian forests. The study's findings show that low-impact silvicultural treatments increase wood production without harming native understory vegetation or bird habitats.
A photograph taken by a wildlife biology student in 2008 may depict a California wolverine, sparking further analysis and investigation. The animal's presence has not been confirmed since the 1920s, but forest service scientists believe it is a rare sighting.
The latest guide from USDA Forest Service highlights energy conservation as the most significant benefit of urban trees in temperate interior West. A mature hardwood tree can bring annual savings of $40 in electricity and $15 in heating costs, while reducing power plant emissions.
Researchers have identified potential habitats in the central and northern Sierra Nevada Mountains for reintroducing California fishers, a rare and elusive carnivore. The study suggests caution in implementing reintroduction efforts due to limited connectivity and distance from existing populations.
Scientists used detection dog teams to study a Pacific fisher population in the Sierra National Forest, finding dogs three and a half times more successful than cameras. The method also only needed one visit per site, aiding land management decisions by providing insights into ecosystem health.
A four-year study will investigate restoration practices in Hawaii's most degraded ecosystems, providing concrete information to restore remaining dry forests and break invasive species/wildland fire cycles. The project aims to improve Department of Defense land management in the Pacific region.
