Rim Fire


The Project: Monitor Change – The Rim Fire

Watching a forest zone regrow after a fire event is a stunning and surprising vision. Given the severity of vegetation and soil burn in the Rim Fire zone, it's regrowth patterns are a source an education to everyone how the Tuolumne River Watershed will regrow – how quickly, what species, how will it look during rain events, what level of erosion? The forest in the watershed burnt differently in different areas.

You can help Monitor Change in the Rim Fire area

1. Take a picture!

Wholly H2O, The Stanislaus National Forest Service, and Nerds For Nature banded together to set up crowd-sourcing photo sites throughout fire impacted areas the Stanislaus National Forest.

As you are hiking through the forest, stop, place your camera in the site stand, snap a shot and upload it to Twitter, Instagram, or Flickr using the hashtag indicated on the sign (Example, #rimfire01, #rimfire02).

2. Observe the Regrowth!

Project Background

The Rim Fire charred more acreage in the Sierra Nevada than any wildfire in recorded history. On August 17th, 2013, an illegal campfire gone wild started by a hunter, began it's months long burn through parts of Yosemite National Park and the Stanislaus National Forest, primarily in the Tuolumne River's watershed.

Within a few short weeks, the Rim Fire scorched through 257,314 acres, or 402 square miles, an area roughly 8 times the size of the City of San Francisco.

Tuolumne River Watershed

The Tuolumne River is the water supply for San Francisco and numerous other cities in the Bay Area, as well as the Turlock and Modesto Irrigation Districts.

Water agencies sell the Tuolumne River's water and electricity to over 2.6 million people and businesses in the San Francisco Bay Area, as well as to farmers for agricultural irrigation water in the Central Valley.

The Rim Fire will continue to have impacts in this watershed for many years to come. Monitor Change: Rim Fire will assist in documenting the ecosystem's recovery.
