Hayman Fire Science Symposium: Lessons Learned After Ten Years of Recovery, Rehabilitation, and Restoration

Events Posted on: November 09, 2015
Logo for the Hayman Fire Science Symposium. The Hayman Fire started on June 8, 2002, 95 miles southwest of Denver, CO.

Manitou Experimental Forest

Experimental Forests and Ranges Posted on: September 09, 2015
Established in 1936, the Manitou Experimental Forest covers 16,700 acres (6,758 ha) in central Colorado. Early research at Manitou focused on range and watershed management, but the scope of research has expanded significantly over time. Today researchers are studying diverse questions related to meteorology, ecology, and biology.

A decade after the 2002 Hayman Fire, understory plant communities are diverse and productive

Science Spotlights Posted on: August 19, 2015
Many of today’s fires in Colorado Front Range forests (ponderosa pine/ Douglas-fir) are burning more severely than they did historically, and some people are concerned that burned understory plant communities will not recover without intervention. In 2002, Colorado’s Hayman Fire burned research plots used to sample understory plant communities, providing an opportunity to address these concerns. We found that burning promoted diverse and productive native understory communities, even in severely burned areas, suggesting that concerns may be unwarranted.

Water quality effects following a severe fire

Documents and Media Posted on: August 11, 2015
On June 8, 2002, the Hayman Fire ignited in the Upper South Platte watershed of the Colorado Front Range. That year, total precipitation and the winter snowpack in the area were approximately half of long-term annual averages, and low fuel moisture, low relative humidity, and strong, gusty winds triggered rapid rates of fire spread and long-range spot fires.Document Type: Other Documents

Understory vegetation following the 2002 Hayman Fire in Colorado (2003-2015)

Projects Posted on: April 14, 2015
Many of today’s fires in ponderosa pine dominated forests are burning more severely than historical ones, generating concern that understory plant communities will not recover without intervention.  There are also concerns that fires will facilitate the establishment and spread of non-native species.  In 2002, Colorado’s Hayman Fire burned pre-existing understory vegetation plots and provided an opportunity to address these concerns. 

Tree regeneration in high-severity burn patches in southwestern ponderosa pine forests

Projects Posted on: April 13, 2015
Numerous factors influence the establishment and growth of tree seedlings after high-severity wildfires. Understanding spatial patterns and environmental conditions influencing ponderosa pine and aspen regeneration post-wildfire can help managers monitor natural recovery.

Reducing post-fire runoff and sediment yields

Documents and Media Posted on: January 23, 2015
Agricultural straw, hydromulch (a matrix of organic fibers mixed with water that binds to soil), and wood shred or wood strand mulches increasingly are being used as postfire hillslope treatments. However, the differences in effectiveness in reducing measured runoff, sediment yields, and peak flow rates among these mulch treatments are not fully understood.

Ten years of vegetation assembly after a North American mega-fire

Publications Posted on: October 03, 2014
Altered fuels and climate change are transforming fire regimes in many of Earth's biomes. Postfire reassembly of vegetation - paramount to C storage and biodiversity conservation frequently remains unpredictable and complicated by rapid global change.

Understorey plant community dynamics following a large, mixed severity wildfire in a Pinus ponderosa-Pseudotsuga menziesii forest, Colorado, USA

Publications Posted on: September 26, 2014
In 2002, the Hayman Fire burned across 55 800 ha of Colorado Front Range P. ponderosa-P. menziesii forest. Also burned in the fire were 20 upland and five riparian plots within a 400-ha study area. These plots had been surveyed for understorey plant composition and cover 5-6 yrs prior. We re-measured all plots annually from 2003 to 2007, 1-5 yrs post-fire.
