The Relationship

The post-fire response of vegetation reflects not only a single fire event but is the result of cumulative effects of previous fires in the landscape. For effective ecological fire management there is a need to better understand the relationship between different fire regimes and vegetation structure. The study investigated how different fire regimes affect stand structure and composition in subtropical eucalypt woodlands of central Queensland. We found that fire history category (i.e. specific combinations of time since fire, fire frequency and season of last burn) strongly influenced richness and abundance of species categorised as mid-storey trees and those individuals currently in the mid-level strata. Time since fire and fire frequency appeared to have the strongest influence. A longer time since fire (>4 years since last burn), combined with infrequent fires (<2 fires in 12 year period) appeared to promote a dense mid-storey with the opposite conditions (<4 years since last burn; >2 fires in 12 year period) promoting more-open woodlands. Consideration of these combined fire regime attributes will allow fire managers to plan for a particular range of fire-mediated patches to maintain the desired diversity of vegetation structures.

We focussed on the influence of historical fire and varied fire management practices on the structure of globally endangered pine rockland ecosystems on two adjacent islands in the Florida Keys: Big Pine Key and No Name Key. We reconstructed fire history in two stands from fire scars on South Florida slash pines (Pinus elliottii Engelm. var. densa Little & Dor.) that were accurately dated using dendrochronology, and quantified stand structure to infer successional trajectories. Fire regimes on Big Pine Key and No Name Key over the past 150 years differed in fire return interval and spatial extent. Fire scar analysis indicated that fires burnt at intervals of 6 and 9 years (Weibull median probability interval) on Big Pine Key and No Name Key with the majority of fires occurring late in the growing season. On Big Pine Key, pine recruitment was widespread, likely due to multiple, widespread prescribed burns conducted since 2000. No Name Key experienced fewer fires than Big Pine Key, but pines recruited at the site from at least the 1890s through the 1970s. Today, pine recruitment is nearly absent on No Name Key, where fire management practices since 1957 could result in loss of pine rockland habitat.

The impact of settlement era fires on Appalachian forests was substantial, but whether these fires affected the extent of fire-adapted ridgetop plant communities is poorly understood. Here we present fire history and stand structure of an Appalachian ridgetop (Pike Knob, West Virginia) based on fire scars from three species (Pinus pungens Lamb., Pinus resinosa Soland., and Quercus rubra L.) and stand structure from two species (P. pungens and P. resinosa). Our research objectives are to determine (i) the degree to which the fire frequency on Pike Knob was affected by European American settlement (~1780–1900) and (ii) how the history of fire on Pike Knob shaped the current age structure of P. resinosa and P. pungens. All three species documented fire activity beginning in the mid- to late 1800s and continuing into the middle of the 20th century, when pasture lands were most active. The majority of P. pungens and P. resinosa established during or shortly after the ~85-year period of fires (1868–1953), suggesting a strong influence of past land use on current forest composition. Ridgetop pine communities have been resilient to both the absence of fire and frequent fire, indicating that pine communities will also be resilient to modern fire management, whether fire is excluded or re-introduced.

Pine Stands

Israel's largest naturalPinus halepensisMill. forest is on the Mt. Carmel range and belongs to the distinct East Mediterranean genetic group. Most of this forest is the result of invasion of abandoned fields and grazing lands, resulting in a heterogeneous pine forest with an understory of broad-leaf shrubs and trees. Species composition, vegetation cover, pine-stand structure, and pine genetic diversity of plots in sites of known fire history, burned 5, 11, and 20 years ago, were studied with adjacent unburned sites forming a chronosequence.Except for annual species, no species replacement took place during post-fire succession. The main observed changes were in the cover of species and of plant life forms. The ratio of tree/dwarf-shrub cover was found to be linearly related to the number of years elapsed since the last fire. Therefore, this ratio could serve as an index to determine the successional stage of Aleppo pine stands with unknown fire history. It is estimated that 30–40 years are needed for full recovery of Aleppo pine stands after fire, depending upon site quality. The stands of post-fire regeneration are of uniform age and are less variable in their structure than unburned stands. The genetic distance among the variousPinus halepensissubpopulations was found to be very small; most of the genetic variability was due to within-subpopulations variability, with almost no variability among subpopulations. Alleles that are typical of West MediterraneanP. halepensispopulations or ofP. brutia, were found in two post-fire subpopulations (stands), indicating pre-fire cross pollination between nativePinus halepensistrees and trees in adjacent pine plantations of foreign origin.The conclusion is that fire has little effect on species composition and on vegetation structure, but that it alters the Aleppo pine stand structure.

The fire history and stand structure (size, age, horizontal pattern) of red fir (Abiesmagnifica A. Murr) forests were studied in two 3.0-ha plots and a larger study area (400 ha) on the Swain Mountain Experimental Forest to identify the fire regime and the effects of fire on stand structure. The fire record in stumps spanned the period 1740–1985. Fires occurred in the 400-ha study area on average every 12.9 years (range 1–57 years), in plot 1 every 18.6 years (range 7–47 years), and in plot 2 every 15.7 years (range 1–45 years). Larger fires recorded in both plots and throughout the larger study area occurred every 26.2 years (range 11–47 years). Average fire-free intervals were shorter (7.9 years) during the settlement–pre-fire-sup-pression period (1851–1934) than during the presettlement (1740–1850) (21.4 years) and fire-suppression (1935–1985) (17.3 years) periods. Severe fires initiated large cohorts of red and white fir (Abiesconcolor (Gord. & Glend.) Lindl.), while low-severity fires probably caused thinning and initiated small patches of trees.
