Fire Exclusion

Abstract Background Vegetation of the Cumberland Plateau (USA) has undergone dramatic transitions since the last glaciation and particularly since the onset of widespread logging and twentieth century fire exclusion. Shortleaf pine (Pinus echinata Mill.), one of the most fire-dependent conifers in the US, occurs throughout the Cumberland Plateau, but its abundance has declined dramatically since Euro-American settlement and continues to decline. To better understand the historical ecology of fire within the natural range of shortleaf pine, we reconstructed fire regimes at three new sites throughout the central and southern Cumberland Plateau region based on fire scars on shortleaf pine trees. Results Fire event chronologies extended back to the seventeenth century and revealed historical fire regimes that were frequent and dominated by dormant-season and low-severity events. Fires occurred on average every 4.4 to 5.3 years at the study sites before widespread Euro-American settlement, and were more frequent (2.3 to 3.8 years) following settlement. Cumberland Plateau fires may be linked to adjacent ecoregions such as the Eastern Highland Rim to the west. Among all sites, we found that long-term trends in fire activity were similar and fit into a regional waveform pattern of fire activity likely driven by humans (i.e., Native American depopulation, European settlement, and twentieth century fire exclusion). Conclusions The decline in shortleaf pine and other fire-dependent ecosystems across the Cumberland Plateau is due to multiple interacting factors and, based on these data, frequent fire should be considered a historically important ecological driver of these systems.

Fire Activity

<p>The 2019/20 forest fires in eastern Australia burned over 5.8 million hectares of mainly temperate broadleaf forest between September 2019 and January 2020. This burned area figure is expected to rise over the remainder of the austral summer, but is already an order of magnitude larger than the mean annual burned area for Australian forest fires over the last 20 years, which is ~0.59 Mha per year. Here we show that this forest fire event is of a record-breaking scale, both nationally and globally, and was pre-conditioned by wide-spread prolonged drought and extreme heat.</p><p>We analysed global remotely sensed burned area data for 2000-2019 to estimate annual burned area fractions of all continental forest biomes. The annual burned area fraction, which is related to the length of fire intervals and other aspects of fire regimes, allows us to compare levels of fire activity across different forest biomes and continents.</p><p>Though very large fires occur in some forest biomes, such as the boreal forests of North-America and Asia, over the 20 years covered by our data set, annual burned area fractions have been very small (<0.03) for nearly all continental forest biomes including Australia’s temperate broadleaf forest biome. These findings provide a global historical reference for the interpretation of the scale of the 2019/20 eastern Australian mega forest fires.</p><p>With fire activity in all forest biomes strongly constrained by the moisture content of the fuels, explanations for the unconstrained burning of millions of hectares of temperate broadleaf forest in a single season must be sought in the extreme drought that has affected eastern Australia for the last two years. We use gridded daily soil moisture predictions for the continent to show how widespread and prolonged dryness set the stage for the unprecedented forest fire event of 2019/20.</p>

The 1960S

A vibrant American Indian art scene developed in California from the 1960s to the 1980s, with links to a broader indigenous arts movement. Native American artists working in the state produced and exhibited paintings, prints, sculptures, mixed media, and other art forms that validated and documented their cultures, interpreted their history, asserted their survival, and explored their experiences in modern society. Building on recent scholarship that examines American Indian migration, urbanization, and activism in the twentieth century, this article charts these developments and argues that American Indian artists in California challenged and rewrote dominant historical narratives by foregrounding Native American perspectives in their work.

The need for a comprehensive and mechanistic understanding of competition has never been more important as plants adapt to a changing environment and as forest management evolves to focus on maintaining and enhancing complexity. With the recent decline in shortleaf pine (Pinus echinata Mill.) land area, it is critical to determine the effects of competition on shortleaf pine and its performance against loblolly pine (Pinus taeda L.), the preferred planted replacement. We evaluate differences in shortleaf and loblolly pine 10 year mean basal area increment (BAI) and crown dimensions across a gradient of neighborhoods. Linear mixed-effects regression models were developed using BAI and several crown metrics as responses and crowding, competitor species abundance and identity, and initial size and species identity of focal tree as predictors. Crowding of focal trees negatively impacted BAI and crown size (p < 0.001, respectively). Although loblolly pine had three times higher BAI as compared to shortleaf pine within similar neighborhoods, BAI was variable, and the crowding effect did not differ between shortleaf and loblolly pine (p ranged from 0.51–0.99). Competitive impacts on focal trees did not differ by competitor identity (p ranged from 0.07–0.70). Distance-independent competition indices better explained the variation in BAI and horizontal crown metrics, while distance-dependent size ratios were more effective at evaluating vertical crown metrics. These findings highlight shortleaf pine competitive potential in mature, natural-origin stands and provide support for the restoration of pine–hardwood and hardwood–pine stratified mixtures as well as management of shortleaf pine at long rotations.

Fire Exclusion

Like many fire-adapted ecosystems, decades of fire exclusion policy in the Rocky Mountains and Foothills natural regions of southern Alberta, Canada are raising concern over the loss of ecological integrity. Departure from historical conditions is evaluated using median fire return intervals (MdFRI) based on fire history data from the Subalpine (SUB), Montane (MT) and Upper Foothills (UF) natural subregions. Fire severity, seasonality and cause are also documented. Pre-1948 MdFRI ranged between 65 and 85 years in SUB, between 26 and 35 years in MT and was 39 years in UF. The fire exclusion era resulted in a critical departure of 197–223% in MT (MdFRI = 84–104 years). The departure in UF was 170% (MdFRI = 104 years), while regions of continuous fuels in SUB were departed by 129% (MdFRI = 149 years). The most rugged region of SUB is within its historical range of variation with a departure of 42% (MdFRI = 121 years). More mixed-severity burning took place in MT and UF. SUB and MT are in a lightning shadow pointing to a predominance of anthropogenic burning. A summer fire season prevails in SUB, but occurs from spring to fall elsewhere. These findings will assist in developing fire and forest management policies and adaptive strategies in the future.

Late Twentieth Century

Before the diminished influence of classical psychoanalysis in the late twentieth century, several now-classic studies of sectarian religions contained Freudian psychoanalytic perspectives on religious sects or cults. These studies included Weston La Barre’s analyses of both serpent handlers and the Native American Ghost Dance; Norman Cohn’s panoramic examination of medieval European sectarian apocalyptic movements; and E. P. Thompson’s groundbreaking examination of Methodism within the formation of English working-class consciousness. Regardless of the problems that are endemic to the application of Freudian psychoanalysis to history, the sheer (although sometimes flawed) erudition of these three authors suggests that classical psychoanalysis had an important interpretive role to play in the study of some sectarian and cultic groups.

Abstract Frequently burned old field shortleaf pine (Pinus echinata)–loblolly pine (Pinus taeda) woodlands in the southeastern US provide important wildlife habitat and multiple ecosystem services. Because these communities differ in composition of dominant plant species and have different land use legacies than native pine savannas, the ability to prevent encroachment by off-site broadleaf woody tree species using fire alone is in question. We use a long-term fire experiment to demonstrate that old field pine communities have been prevented from transitioning to hardwood forests for over 50 years through judicious application of prescribed fire applied at 1–2 year intervals, whereas communities with three-year fire intervals show signs of transitioning to hardwood forest. We emphasize tailoring fire regimes to particular contexts of land use history to achieve the most historic and sustainable ecosystem structure and function possible for conservation of native flora and fauna. Study Implications: Demonstrating the ability to maintain natural forest structure of old field loblolly pine–shortleaf pine communities in the southeastern US using frequent prescribed fire has implications for the future sustainability of hundreds of thousands of hectares of such land used to provide critical habitat for many species of imperiled and culturally valued wildlife. It also provides insight into restoration of longleaf pine communities on postagricultural land as promoted by multiple highly funded government initiatives. Frequently burned pine savannas and woodlands are resilient to wildfire and sustain natural hydrological cycles, both important for mitigating the effects of global climate change.

Botanical remains were identified from 27 lots from the Washington Square Mound site (41NA49). The primary occupation at the site is Middle Caddo period in age. The first pooled set of calibrated radiocarbon dates from the site fell into the period A.D. 1268-1302, while a recent set of five calibrated dates from samples of plant remains discussed in this article range from A.D. 1279 + 17; (2) A.D. 1358 + 57; and three dates on charred corn from Features 36, 81, and 86 range from as early as A.D. 1394 to as late as A.D. 1437. These dates as a group fall in the Middle Caddo period; there is limited evidence at the site for other, smaller occupations, including Late Caddo and Late Woodland/Early Caddo. At least three mounds were visible in the nineteenth century. Much of the site was never plowed, a situation that has resulted in intact shallow deposits and unusually large pottery sherds, although a high school has been built over parts of the non-mound site area. Labels of botanical lots that included excavation dates indicate a range from 1979 to 1983, associating the botanical remains with Stephen F. Austin State University Field School excavations that took place during this time. At least nine features are represented in the botanical lots. Four are described as charcoal-filled pits, one as a pit, and one as a post mold. Feature 36 was a corn cob concentration . Botanical lots for Features 62, 81, and 199 are also present. The Washington Square Mound site is situated in the city of Nacogdoches, Texas, on an interfluve between Banita Creek and La Nana Creek, which drain into La Nana Bayou and the Angelina River. The area lies squarely in the Pineywoods ecological zone, the westernmost extension of the great Southeastern Evergreen Forest that reaches across the southeastern United States to the Atlantic coast (Braun 2001:281). The dominant vegetation type in an upland area such as Washington Square during presettlement times would have been a shortleaf pine community, where shortleaf pines (Pinus echinata) share dominance with dry-site oaks such as southern red oak (Quercus falcata), post oak (Q. stellata), and blackjack oak (Q. marilandica), hickories (Carya spp.), and elms (Ulmus spp.) Springs and marshy areas nearby would have offered aquatic and wetland plants such as river cane (Arundinaria gigantea). A spring-fed pond is reported to have existed north of the site, and a marshy area to the southwest. Pollen studies indicate that use of the modern and recent vegetation is appropriate for understanding the plants and attendant animal resources available to occupants of the sites during prehistoric times. Some fluctuations in rainfall and temperature have taken place, however. In addition, more frequent fires would have made the understory in the uplands less prominent than today. Early explorers in East Texas and other parts of the Eastern Woodlands noted the open, park-like nature of many woodlands.

Industrial School

This chapter focuses on the under-examined corpus of Carlisle poetry, viewing it as a vital archive for theorizing the role of the American Indian intellectual tradition in negotiating Americanization discourses at the turn of the twentieth century. Materials published in newspapers and magazines at Carlisle Indian Industrial School in Pennsylvania (1879–1918) include “Carlisle poetry,” which encompasses original poetry by Native American students, reprints of poems by Indian authors, poems by school personnel, and poems by well-known American authors. This poetry, along with the letters and articles published in Carlisle newspapers and magazines, is complicit with the ideological underpinnings of the institution’s ambitious goals of “making” Indian students into Americans, even as elements of this literature critique the Americanization that Carlisle boarding school demanded of its students.
