“…Third, longleaf pine does not regularly produce repeated external scarring (i.e., “cat faces”; Figure 4(a) and (c)) as is commonly found on other pine species (Brockway 2005; Outcalt and Brockway 2010; Huffman and Rother 2017). This could be driven by the lower-intensity fires that characterize these systems; heating along the trunk may remain below thresholds that would produce an open wound.…”

“…This “bolting” period lasts for several years, after which the trees can reach > 5 m in height and begin to mature. As they grow, longleaf pine trees develop thick bark that resists heat damage (Heyward 1939; Gilliam and Platt 1999; Barnett 1999), although cambial damage from passing fires is common, particularly when trees are young, allowing for tree-ring reconstructions of fire history, especially if the earliest growth years can be extracted in samples (Huffman and Rother 2017).…”

The longleaf pine ( Pinus palustris Mill.) and related ecosystem is an icon of the southeastern United States (US). Once covering an estimated 37 million ha from Texas to Florida to Virginia, the near-extirpation of, and subsequent restoration efforts for, the species has been well-documented over the past ca. 100 years. Although longleaf pine is one of the longest-lived tree species in the southeastern US—with documented ages of over 400 years—its use has not been reviewed in the field of dendrochronology. In this paper, we review the utility of longleaf pine tree-ring data within the applications of four primary, topical research areas: climatology and paleoclimate reconstruction, fire history, ecology, and archeology/cultural studies. Further, we highlight knowledge gaps in these topical areas, for which we introduce the Longleaf Tree-Ring Network (LTRN). The overarching purpose of the LTRN is to coalesce partners and data to expand the scientific use of longleaf pine tree-ring data across the southeastern US. As a first example of LTRN analytics, we show that the development of seasonwood chronologies (earlywood width, latewood width, and total width) enhances the utility of longleaf pine tree-ring data, indicating the value of these seasonwood metrics for future studies. We find that at 21 sites distributed across the species’ range, latewood width chronologies outperform both their earlywood and total width counterparts in mean correlation coefficient (RBAR = 0.55, 0.46, 0.52, respectively). Strategic plans for increasing the utility of longleaf pine dendrochronology in the southeastern US include [1] saving remnant material ( e.g., stumps, logs, and building construction timbers) from decay, extraction, and fire consumption to help extend tree-ring records, and [2] developing new chronologies in LTRN spatial gaps to facilitate broad-scale analyses of longleaf pine ecosystems within the context of the topical groups presented.

“…efforts to adjust seasonal classification of fire scars to local needs (Huffman et al 2004, Huffman 2006, White and Harley 2016 and will improve the accuracy and usefulness of fire-scar data for understanding historical fire regimes in pine savannas of the North American Coastal Plain. This work is timely given that few tree-ring based fire-history studies have been conducted in pine savannas of this region (but see: Huffman et al 2004, Henderson 2006, Huffman 2006, Stambaugh et al 2011, Harley et al 2013, White and Harley 2016 and that more studies are anticipated following developments in field methodologies (Huffman and Rother 2017).…”

“…The sampling plots were selected according to testimonies of landowners who indicated the location of sites that experienced fires. Within each plot, we recorded the presence of fire-scarred stumps and logs with visible and buried fire scars, following Huffman and Rother (2017). The latter found that targeting only trees with evidence of external scarring is not effective when buried fire scars are abundant.…”

Fire scar analysis is a fundamental tool for reconstructing fire regimes in conifer forests. However, little is known about fire scar properties in tropical montane conifers, where some assumptions limit dendroecological research. These include that fir species do not exhibit external fire scars and that pines without external fire scars have not experienced past fires. This study describes fire scar patterns in two conifer species growing in Mexican temperate forests: sacred fir (Abies religiosa) and smooth-bark Mexican pine (Pinus pseudostrobus). We extracted cross-sections from 110 trees and measured tree age, basal diameter, bark thickness, fire scar size and seasonality, the number of scars per tree, years and basal diameter from pith to the first scar, and the proportion of external and buried fire scars. Most trees had three fire scars, which appeared during the dry season after the first 15 years measured from the pith. Old and large-diameter trees did not have more fire scars, but the time between fire scars influenced fire scar closure in sacred firs. Bark thickness and the proportion of visible and buried fire scars were similar in both species. Our results suggest that the absence of visible fire scars in smooth-bark Mexican pines does not imply the absence of fire, and sacred firs can exhibit external fire scars like pines.
