Check out this great presentation on fire ecology and the importance of mixed severity fires by Dominick DelaSalla, PhD.
Here is a wonderful video summarizing the importance of post-fire ecosystems by the Wild Nature Institute:

FIRES, INCLUDING HIGH SEVERITY FIRES, ARE GOOD FOR FORESTS
The Forest Service needs to do away with post-fire (“salvage”) logging on all National Forests. Post-fire logging is an outdated, ecologically destructive practice that harms important and delicate habitats.
Western conifer forests have evolved with fire and are adapted to it, and in fact need fire. Wildfires, including high-severity fires, create important habitats, lessen the severity and frequency of disease and insect outbreaks, and facilitate seed germination in some plant species. Post-fire forests are one of the most biodiverse and important habitats, and are home to many at-risk, sensitive, and listed species. Post-fire areas are rich in snags (standing dead trees) used for nesting and foraging by many species, including woodpeckers. Fires also stimulate the growth of many species of native wildflowers, certain berries and fungi (such as Morels), and provide habitats for small mammals and forage for deer and elk. Post-fire habitats are among the most important for wildlife, and are unfortunately very rare compared to historic proportions because of continued fire-suppression and post-fire logging. In an Open Letter to Members of Congress from 250 Scientists Concerned about Post-fire Logging (2013), scientists state that “Post-fire habitats created by fire, including patches of severe fire, are ecological treasures rather than ecological catastrophes, and that post-fire logging does far more harm than good to the nation’s public lands.”
POST-FIRE LOGGING IS BAD FOR FORESTS
The wealth of scientific studies done on post-fire logging have come to an overwhelming consensus that post-fire logging has extremely negative impacts on numerous species, sensitive ecosystems, snags and downed wood (both very important for wildlife habitats), water quality, and forest regeneration. Richard Hutto, in his study Towards Meaningful Snag-Management Guidelines for Postfire Salvage Logging in North American Conifer Forests (2006) goes so far as to state: “I am hard pressed to find any other example in wildlife biology where the effect of a particular land-use activity is as close to 100% negative as the typical postfire salvage-logging operation tends to be.”
There is no scientific evidence to justify salvage logging on an ecological basis, and projects on public lands should focus on truly restorative activities, such as road removal. Numerous scientific studies point to a suite of possible long-term problems caused by post-fire logging, including erosion, increased sedimentation, soil compaction, and negative impacts to wildlife and hydrology. Post-fire logging can also increase future fire risk. Donato et al. (2006) found that post-fire logging actually increases the risk of future high intensity fires, particularly when slash is left on the ground. Thompson & Spies (2010) found that areas that had previously experienced burning and “salvage” logging after the 1987 Silver Fire in southwestern Oregon had more extensive crown damage during the 2002 Biscuit fire than areas that had not been “salvage” logged after the Silver Fire. Post-fire logging can also negatively affect forests’ ability to regenerate, which can facilitate non-native plant species’ establishment and spread. Post-fire logging can also exacerbate or create problems with invasive species through other mechanisms, such as logging equipment spreading invasive plant seeds.
Post-fire areas are too ecologically valuable to sacrifice for marginal economic benefit to a few individuals and corporations while the public pays for the costs of ecological degradation. Post-fire logging needs to be eliminated on public lands.
