Fire History, Woodland Structure, and Mortality in a Piñon-Juniper Woodland in the Colorado National Monument

  title={Fire History, Woodland Structure, and Mortality in a Pi{\~n}on-Juniper Woodland in the Colorado National Monument},
  author={Deborah Kennard and Amanda J. Moore},
ABSTRACT The Colorado National Monument (COLM), on the northeastern edge of the Uncompahgre Plateau, supports a persistent Piñon (Pinus edulis Engelm.) — juniper (Juniperus osteosperma (Torr.) Little) woodland, which has not been disturbed by large stand-replacing fires since modern fire records began. We examined the fire history of large (> 100 ha) stand-replacing fires, documented tree population structures, and characterized tree density, quadratic mean diameter (QMD), relative… Expand
Stand Dynamics of Pinyon-Juniper Woodlands After Hazardous Fuels Reduction Treatments in Arizona
Abstract Pinyon-juniper ecosystems occur extensively across western North America, and at the landscape scale, variation in structure and composition is influenced by topographic position, soils,Expand
Structural and regenerative changes in old-growth piñon–juniper woodlands following drought-induced mortality
Given the loss of a substantial component of the adult trees, reduced stand structural complexity, and demonstrated need for moist conditions and nurse plants for effective recruitment, old-growth woodlands may be vulnerable to decline under future warm and dry climate projections. Expand
Historical and Modern Fire Regimes in Piñon-Juniper Woodlands, Dinosaur National Monument, United States ☆
ABSTRACT Twentieth-century fire exclusion has produced unnatural and undesirable changes in vegetation structure and dynamics of many rangelands of western North America, but not all kinds ofExpand
Post-Fire Native Seed Use in Western Colorado: A Look at Burned and Unburned Vegetation Communities
ABSTRACT: Wildfires on public lands in the United States are increasing in size and frequency over time. Government agency post-fire treatments often include seeding of native and nonnative plantExpand


Fire history of a central Nevada pinyon–juniper woodland
Our study reconstructed fire history (1445–2006) from tree rings for a Great Basin single-needle pinyon pine (Pinus monophylla Torr & Frem.) – Utah juniper (Juniperus osteosperma (Torr.) Little)Expand
Historical and recent fire regimes in Piñon-Juniper woodlands on Mesa Verde, Colorado, USA
Abstract The fire history of Pinon–Juniper ( Pinus edulis – Juniperus osteosperma ) woodlands in much of the southwestern United States is poorly understood, and as a result, fire managementExpand
Fire History of Piñon-juniper Woodlands on Navajo Point, Glen Canyon National Recreation Area
Abstract Navajo Point, on the southeast tip of the Kaiparowits Plateau, supports Pinus edullis Engelm. var edulis-Juniperus osteosperma (Torrey) Little (piñon-juniper) woodlands undisturbed by largeExpand

Tree populations in these woodlands are in flux, affected by drought and wet periods linked to oceanic-atmospheric variability, Euro-American livestock grazing, and long-rotation, high-severity fires, which corroborate the long-term relationships between age structure and climate. Expand
Fire history of pinyon–juniper woodlands at upper ecotones with ponderosa pine forests in Arizona and New Mexico
We used maps of fire evidence, fire scar dendrochronology, forest age-structure analysis, and landscape analysis to investigate fire history at pinyon pine (Pinus edulis Engelm.) - juniper (JuniperusExpand
Pifion-juniper woodlands (Pinus edulis, Juniperus osteosperma, and J. sco- pulorum) and petran chaparral communities (Quercus gambelii, Amelanchier utahensis, Cercocarpus montanus, and other tallExpand
Fire and restoration of piñon–juniper woodlands in the western United States: a review
Abstract Pinons and junipers, that dominate many semi-arid landscapes in the western United States, have invaded some sagebrush and grassland areas and possibly increased in density sinceExpand
Vegetation changes following fire in the pinyon-juniper type of west-central Utah.
The purpose of this study was to examine the vegetation on burns of various ages and determine the successional patterns following fire, and found that juniper woodlands were well developed 8.5 to 90 years following fire. Expand
Ancient Piñon-Juniper Forests of Mesa Verde and the West: A Cautionary Note for Forest Restoration Programs
Fuel reduction and fire mitigation activities may be linked to restoration of overall forest health, but the two goals do not always coincide. We illustrate the importance of understanding bothExpand
Historical and modern disturbance regimes of pinon-juniper vegetation in the Western U.S.
Pinon-juniper vegetation covers some 100 million acres in the western U.S. where it provides economic products, ecosystem services, biodiversity, and aesthetic beauty in some of the most scenicExpand
