Chaparral Bird Communities Harmed by Shrub Removal: Research Brief

Chaparral Bird Communities Harmed by Shrub Removal: Research Brief

To help managers make science-based decisions that incorporate wildlife information, this study experimentally compared the effects of two pre-fire vegetation reduction treatments (prescribed burning and shrub mastication) on the chaparral bird community.

How can managers consider bumble bees during post-fire management? Research Brief

How can managers consider bumble bees during post-fire management? Research Brief

Bumble bees are important pollinators of native plant species. This brief provides information that can support managers in making nuanced decisions to benefit bumble bees during post-fire management.

Do fuel reduction treatments cause beetle mortality or resilience? Research Brief

Do fuel reduction treatments cause beetle mortality or resilience? Research Brief

During normal levels of beetle activity, fuel treatment reductions either cause no trees to die from beetles or just a few. If tree deaths occur, they reinforce fuel hazard reduction and forest restoration goals.

Pyrodiversity Promotes Avian Diversity in Semi-Arid Forests: Research Brief

Pyrodiversity Promotes Avian Diversity in Semi-Arid Forests: Research Brief

Overall, the results of this study add support to the existing theory that diverse fire increases biodiversity in certain ecosystems. Specifically, this study showed that higher diversity of fire severity patterns within a fire lead to more bird diversity, especially in the fire prone semi-arid forests of the Sierra Nevada.

Response of California Spotted Owls to Fire and Salvage Logging in Southern California: Research Brief

Response of California Spotted Owls to Fire and Salvage Logging in Southern California: Research Brief

In this study, the average core area of the owls’ pre-fire forest habitat was 106 ha with a greater proportion of hardwoods compared to an average core area of 180 ha in the Sierra in which conifers dominate.

5-Years of Small Mammal Response to Fire Severity in a Southern California Mixed Conifer Forest: Research Brief

5-Years of Small Mammal Response to Fire Severity in a Southern California Mixed Conifer Forest: Research Brief

In this 5-year study, the post-fire populations and microhabitat preferences of four small mammal species were compared. The study analyzed preferences in unburned, moderate and high-severity fire in mixed conifer forest.

Perspectives on bird-aspen relationships from the Tahoe region: Presentation PDF

This is a presentation from the Aspen Restoration and Ecology Workshop in 2015. The summary of this presentation is that pure, mature aspen are best for avian species richness and abundance. Specific characteristics of aspen stands that benefit avian species are also discussed.

Yikes! An Old-school Wildlife “Experiment” Involving Fire: Research Brief

This  1952  study  is  a  questionably  designed   attempt  to  measure  wildlife  survival  during   prescribed  fire.  The  most  dubious  part  of  the   project  involves  burying  live-­‐trapped  animals  in   the  path  of  a  controlled  burn.

Type Conversion Leads to Reduced Vertebrate Diversity: Research Brief

Between  the  1940s and  the  1970s,  converting   chaparral  to  grasslands  had  become  acceptable   and  widely  practiced  in  western  states. How these type conversions affected vertebrate diversity were addressed in this study.

Three-year Mashing Operations for Better Deer Forage: Research Brief

In  the  interest  of  increasing browse  for deer   populations  on  California  chaparral lands,  a   brush  manipulation  program was  conducted by   the  California  Department  of  Fish & Game  (CDFG) from  1955  to  1960. The results of this project are discussed in this brief.
