Characterizing a Poacher-Driven Fire Regime in Low-Nutrient Coastal Grasslands of Pondoland, South Africa

Authors: Christopher F. Brooke, Tineke Kraaij, and Jan A. Venter
Pages: 1-16
DOI: 10.4996/fireecology.14010106

Understanding fire regimes in the coastal region of the Pondoland center of plant endemism, (Eastern Cape, South Africa) is of critical importance, especially in areas where anthropogenic ignitions influence the fire regime. We characterized the fire regime (2007 to 2016) of Mkambati Nature Reserve (9200 ha) in terms of fire season, seasonality of fire-prone weather conditions, fire return interval (FRI), and influence of poaching-related ignitions. Fires were concentrated in winter when monthly fire danger weather index was highest.

Modeling Fire Pathways in Montane Grassland−Forest Ecotones

Authors: Joshua L. Conver, Donald A. Falk, Stephen R. Yool, and Robert R. Parmenter
Pages: 17-32

Fire plays a key role in regulating the spatial interactions between adjacent vegetation types from the stand to the landscape scale. Fire behavior modeling can facilitate the understanding of these interactions and help managers restore or maintain fire’s natural role. The Valles Caldera National Preserve (VALL), in the Jemez Mountains of northern New Mexico, USA, contains one of the largest montane grasslands in North America and extensive areas of grassland−forest ecotone.

Dormant-Season Fire Inhibits Sixweeks Fescue and Enhances Forage Production in Shortgrass Steppe

Authors: Nickolas A. Dufek, David J. Augustine, Dana M. Blumenthal, Julie A. Kray, and Justin D. Derner

Semiarid rangelands experience substantial interannual variability in precipitation, which can determine the relative abundance of species in any given year and influence the way that fire affects plant community composition and productivity. Long-term studies are needed to examine potential interactions between fluctuating community composition and the role of fire in these ecosystems. Here, we report on an 11-year (2006 to 2016) study of annual and triennial dormant-season prescribed fires in the semiarid shortgrass steppe of Colorado, USA.

Seasonal Patterns and Drivers of Ashe Juniper Foliar Live Fuel Moisture and Relevance to Fire Planning

Authors: W. Matt McCaw, Devin M. Grobert, S. Bruce Brown, Sam Strickland, Guy A. Thompson, Glen Gillman, Lucien M. Ball, and Christopher D. Robinson
Pages: 50-64
DOI: 10.4996/fireecology.140150064

Foliar live fuel moisture (LFM)the weight of water in living plant foliage expressed as a percentage of dry weighttypically affects fire behavior in live wildland fuels. In juniper communities, juniper LFM is important for planning prescribed burns and wildfire response but can be time consuming to obtain regularly. Also, there has been little analysis of the ways in which juniper LFM varies seasonally or is affected by weather conditions, soil moisture, or other variables such as drought index.
