Wildland fires play a key role in the functioning and structure of vegetation.  The availability of sensors aboard satellites, such as Moderate Resolution Imaging Spectroradiometer (MODIS), makes possible the construction of a time series of vegetation indices (VI) and the monitoring of post-fire vegetation recovery.  One of the techniques used to monitor post-fire vegetation is the comparison of a burned site with an adjacent unburned control site.  However, to date, there is no objective method available for selecting these unburned control sites.

Vegetation Responses to Season of Fire in Tallgrass Prairie: A 13-Year Case Study

Fire regulates vegetation composition of fire-dependent grasslands in North American tallgrass prairies.  We measured the vegetation response to prescribed fire seasonality by burning in two-month increments every two years, from 2004 to 2015, west of Stillwater, Oklahoma, USA.  Fire exclusion or burning in any season led to an in increase in woody plant cover ranging from 18 % to 63 %, except for September through October, which showed no increase.

Historical Fire–Climate Relationships in Contrasting Interior Pacific Northwest Forest Types

Describing the climate influences on historical wildland fire will aid managers in planning for future change.  This study uses existing historical climate reconstructions and a new fire history from the southern Blue Mountains in eastern Oregon, USA, to: 1) characterize historical fire-climate relationships, and 2) determine if climatic influences on fire differed among dry sites dominated by ponderosa pine (Pinus ponderosa Dougl. ex Laws) and more productive sites with significant older fire intolerant grand fir (Abies grandis [Dougl.] Lindl.) structure.

Black Carbon on Coarse Woody Debris in Once- and Twice-Burned Mixed-Conifer Forest

One important outcome of wildfire is the production of charcoal.  Charcoal is highly resistant to decomposition and its physical and chemical properties enhance soil fertility and influence nutrient cycling.  We compared the amount of black C (the carbon fraction of charcoal) on coarse woody debris (CWD; ≥7.6 cm diameter) and total CWD biomass at sites burned once in a high-severity fire with sites that burned in an initial high-severity fire and then reburned eight to ten years later.

Fire Reduces Fungal Species Richness and In Situ Mycorrhizal Colonization: A Meta-Analysis

Soil fungal communities perform many functions that help plants meet their nutritional demands.  However, overall trends for fungal response to fire, which can be especially critical in a post-fire context, have been difficult to elucidate.  We used meta-analytical techniques to investigate fungal response to fire across studies, ecosystems, and fire types.  Change in fungal species richness and mycorrhizal colonization were used as the effect size metrics in random effects models.

Accurate prediction of fire-caused tree mortality is critical for making sound land management decisions such as developing burning prescriptions and post-fire management guidelines.  To improve efforts to predict post-fire tree mortality, we developed 3-year post-fire mortality models for 12 Western conifer species—white fir (Abies concolor [Gord. & Glend.] Lindl. ex Hildebr.), red fir (Abies magnifica A. Murray bis), subalpine fir (Abies lasiocarpa [Hook.] Nutt.), incense cedar (Calocedrus decurrens [Torr.] Florin), western larch (Larix occidentalis Nutt.), lodgepole pine (Pinus contorta Douglas ex Loudon var. latifolia Engelm. ex S. Watson), whitebark pine (Pinus albicaulis Engelm.), ponderosa pines (Pinus ponderosa Lawson & C. Lawson var. scopulorum Engelm and var. ponderosa C. Lawson), Jeffrey pine (Pinus jeffreyi Balf.), sugar pine (Pinus lambertiana Douglas), Engelmann spruce (Picea engelmannii Parry ex Engelm.), and Douglas-fir (Pseudotsuga menziesii [Mirb.] Franco var. glauca [Beissn.] Franco)—by pooling data collected from multiple fire-injury studies.

Fire Response to Local Climate Variability: Huascarán National Park, Peru

In Huascarán National Park (HNP), Peru, grazing and anthropogenic burning have been interacting for decades with natural ignitions and climate variability to reconfigure the fire regimes of the vegetative communities.  However, over the last few decades, human alterations to the region’s fire regime were perceived by resource managers to have led to an overall increase in fire occurrence and fire extent.  Resource managers are now very concerned about the impacts of increasing anthropogenic fires in the National Park because these fires seem to disrupt ecological processes and tourism.
