Intersecting a wildfire polygon layer with Areas of Conservation Emphasis

AprilWheeler

I am trying to intersect two layers. I am trying to intersect California Fire Perimeters 1879-2021 https://www.arcgis.com/home/item.html?id=6fd0d8d6f47d414da7bcb1dcd0539999 with Areas of Conservation Emphasis (ACE) https://wildlife.ca.gov/Data/Analysis/Ace#523731770-species-biodiversity to determine based on wildfires for the past 10 years, which of those wildfires intersect with the most vulnerable (score 2 or lower) areas of conservation interest. For Species Biodiversity, I am able to select the data that contains a 2 or lower, but I cannot figure out how to intersect Species Biodiversity with the wildfires to show an overlap. I tried the intersect tool and it produced a layer, but it was just a blank map that showed nothing. Please help.

Hi AprilWheeler,

Intersect is good.

You have to make a selection by attribute on the wildfires during the last decade for the fires

and 

You have to make a ACE selection by attribute of 2 or less.

You can also use the Calfire data file at https://gis.data.ca.gov/datasets/CALFIRE-Forestry::california-fire-perimeters-all-1/about . I think its a vector file. 

There's also a Calfire Perimeter 1950+ file located here: https://gis.data.ca.gov/datasets/CALFIRE-Forestry::california-fire-perimeters-all/explore?layer=2 

Try those and let us know how you did.
