A través del humo: Búhos moteados, incendios forestales, y restauración forestal

Documents and Media Posted on: February 09, 2021
 En el suroeste, los científicos y los administradores están trabajando juntos para encontrar formas de reducir el riesgo de futuros mega fuegos y al mismo tiempo mantener el hábitat crítico de anidación. Document Type: Other Documents

Where have all the Pinyon Jays gone?

Science Spotlights Posted on: January 27, 2021
We found Pinyon Jays prefer distinct forest conditions within woodlands for specific activities. These conditions are often present in places targeted for active woodland management. This research provides land managers knowledge they can incorporate into woodland prescriptions that meet management objectives for the treatment area while also benefiting the Pinyon Jay.

Through the Smoke: Spotted Owls, Wildfire, and Forest Restoration

Documents and Media Posted on: December 05, 2020
In the Southwest, scientists and managers are working together to find ways to reduce the risk of future megafires while also maintaining critical nesting habitat for Mexican spotted owls.  Document Type: Other Documents

Warning signals of tree mortality masked by extreme drought and bark beetles

Science Spotlights Posted on: November 09, 2020
Determining why some trees die while others survive both drought and insect outbreaks is valuable for forecasting tree mortality events, which are expected to become more frequent with further climate change. We collected stand and tree-level data on the Sierra and Los Padres National Forests in Central and Southern California, where tree mortality from the combination of drought and bark beetles was widespread. 

Is severe fire good or bad for spotted owls?

Science Spotlights Posted on: October 08, 2020
Whether severe fire is good or bad for spotted owls will influence how some forests are managed for fire risk. In reality, the effects of severe fire on spotted owls depends on the size of severely-burned patches, as well as their configuration and complexity. Owls actively use small patches of severely-burned forest, but they avoid larger patches and will abandon territories that are extensively affected by severe fire.

Myrtle rust pathogen: evaluating genetic diversity and invasive threats

Science Spotlights Posted on: August 31, 2020
At least three different biotypes (genetic groups) of the invasive myrtle rust pathogen (Austropuccinia psidii) were identified, each with different host associations, geographic distributions, and potential distribution (suitable climate space). Each biotype poses its own distinct invasive threats to diverse hosts in the Myrtaceae (e.g., eucalypts, guava, ‘ōhi’a) grown in different geographic areas.

Termites: Insights into below-ground engineers and soil processes

Science Spotlights Posted on: August 27, 2020
Termites alter wood and coarse root decomposition by direct feeding, and they may directly or indirectly change fungal community structure and activity, which can also alter wood decay. Their contributions to belowground decay and organic matter movement within the soil may be a critical piece of information for understanding how long roots may last in the soil and when steep slopes may fail.

Increasing use of prescribed fire: Barriers and opportunities

Science Spotlights Posted on: August 20, 2020
Prescribed fire is an important tool for increasing the resilience of fire-dependent ecosystems and for reducing overall wildfire risk, but it is not being applied at the necessary or desired levels. We investigated barriers and strategies for facilitating prescribed fire application on USFS and BLM lands across the western United States.

Habitat suitability models for white-headed woodpecker in recently burned forest

Science Spotlights Posted on: August 11, 2020
Salvage logging in burned forests can negatively affect habitat for white-headed woodpeckers (Dryobates albolarvatus), a species of conservation concern. To quantify and map suitable woodpecker habitat after wildfires, we developed habitat suitability index (HSI) models to inform forest management activities.

Understanding community trust in wildfire management agencies

Science Spotlights Posted on: August 10, 2020
Trust is an essential element in building and maintaining successful partnerships with stakeholders and community members. Findings indicate that managers hoping to build, maintain, or restore trust with communities therefore may want to focus on active communication, and demonstrating competence and how actions are in the best interest of the community.
