Plot Shape Effects on Plant Species Diversity Measurements: USGS Research Brief

Previous researchers have advocated that to obtain maximum diversity one must position rectangular plots along the environmental gradient that generates the highest species turnover. In the ecosystems studied here there was no evidence of consistent trends along gradients either perpendicular or parallel to the slope contour.

Permanently Converting Chaparral to Rangeland: Research Brief

 In the 1940's California  Division  of  Forestry   (CDF) rangeland  managers believed  that the  grazing   capacity of the California foothills had decreased due to  weedy  herbs  and  invading   chaparral. The most effective methods were explored to convert chaparral to rangeland.

Non-resprouting Chaparral is Decimated by Repeated Fires: Research Brief

Using  GIS  fire  history  data,  1930-­‐1934  VTM  maps   and  modern  vegetation  maps,  four  experimental   sites  with  short  fire  return    intervals  (<6  years)   were  paired  to  four  control  sites  with  similar   vegetation,  slope,  aspect  and  elevation  but  with   longer  fire  intervals  (>12  years).

Modeling How Fire Frequency Alters Species Composition: Research Brief

Janet  Franklin  and  colleagues  used  LANDIS,  a   landscape  disturbance  and  succession  model  to   investigate  how  short,  moderate  and  long  fire   return  intervals  (FRI's)  in  southern  California   affect  persistence  of  different  shrub life  histories.

Managing forests and fire in changing climates: Policy Forum Research Brief

In some ecosystems, high-severity regimes are appropriate, but climate change may modify these fire regimes and ecosystems as well. Some undesirable impacts may be avoided or reduced through global strategies, as well as distinct strategies based on a forest’s historical fire regime.

Large California Fires Cause Shift in Reptile and Amphibian Assemblages: USGS Research Brief

In 2003, Southern California experienced several large fires that burned thousands of hectares of wildlife habitats and conserved lands. A USGS study published in the Journal of Herpetology reports that after the fires, burned chaparral and coastal sage scrub (CSS) plots lost herpetological diversity and displayed a significant shift in overall community structure.

Invasive Plants and Fire in the Deserts of North America: USGS Research Brief

In a recent publication by USGS scientists, Drs. Matthew L. Brooks and David A. Pyke discussed these interrelationships, and concluded that the management of fire and invasive plants must be closely integrated for each to be managed effectively.

Interactions among wildland fires in a long-established Sierra Nevada natural fire area: Research Brief

 A   2009  study  by  Collins  et  al.  suggests  that  freely   burning  fires  in  upper  elevation  mixed-­‐conifer   forests  of  the  Sierra  Nevada  may  effectively   regulate  fire-­‐induced  effects  across  an  entire   landscape.

Influence of conifer encroachment & fire on CA black oak: Research Brief

Tree  and  shrub  encroachment is  common  in  areas   where  fire  has  been  excluded,  and  has  become  a   focal  point  of  many  oak  management  and   restoration  programs.

Hydrologic Changes After 40 Years of Type Conversion: Research Brief

Four decades after being type converted to a non native grassland, the soil and hydrology of the USFS San Dimas Experimental Forest in southern California was compared to the adjacent, natural chaparral.

Human Influence on California Fire Regimes: USGS Research Brief

Researchers studied the human influence on fire regimes at the WUI using California Department of Forestry and Fire Protection (CDF) data from a majority of counties in the state, coupled with associated housing and other human infrastructure data.
