High Hazard Zones Viewer App

From 2012-2015 California faced the worst epidemic of tree mortality in modern history. Multiple years of drought, combined with an infestation of native bark beetles, contributed to the death of millions of trees on federal, state, and private lands across California. 

This viewer was brought to you by the Tree Mortality Task Force (TMTF), which was coordinated by the California Governors office between 2015 and 2018. The TMTF was comprised of multiple agencies, entities and stakeholders working together to address the Tree Mortality crisis. This viewer includes various layers related to the tree mortality problem, including Aerial Detection Survey data (depicting areas of dead trees), High Hazard Zones, tree removal projects, and others.

California Historical Wildland Fire Perimeters Exploratory Map
CAL FIRE's Fire and Resource Assessment Program (FRAP) annually maintains and distributes an historical fire perimeter dataset from across public and private lands in California. The GIS data is developed with the cooperation of the United States Forest Service Region 5, the Bureau of Land Management, the National Park Service and the United States Fish and Wildlife Service and is released in the spring with added data from the previous calendar year. Although the dataset represents the most complete digital record of fire perimeters in California, it is still incomplete, and users should be cautious when drawing conclusions based on the data. 

This map highlights the recent large fires (≥5,000 acres) on a backdrop of all of the dataset's documented fire perimeters dating back to 1878.
  This map includes perimeters symbolized by decade, county boundaries, California vegetation, and NAIP imagery back to 2005.  
Popups provide a narrative of known details pertaining to each incident, including alarm and containment dates, GIS calculated acreage, and responding agency, among other attribution.
This is the landing page map in the California Historical Wildland Fire Perimeters Exploratory App.
