A Unique old-growth ponderosa pine forest in northern Arizona
Old-growth ponderosa pine (Pinusponderosa) forests are uncommon in the Southwest, and only one old growth forest (the Gus Pearson Natural Area [GPNA]) has been researched in the ponderosa pine belt sur rounding the city of Flagstaff in northern Arizona. The purpose of this study was to measure soil characteris tics, current and pre-Euro-American settlement (1885) tree structure, and understory ...
متن کاملNOTE / NOTE Dwarf mistletoe effects on fuel loadings in ponderosa pine forests in northern Arizona
Southwestern dwarf mistletoe (Arceuthobium vaginatum (Willd.) J. Presl ssp. cryptopodum) infests about 0.9 million ha in the southwestern United States. Several studies suggest that dwarf mistletoes affect forest fuels and fire behavior; however, few studies have quantified these effects. We compared surface fuel loadings and predicted fire behavior among four levels of dwarf mistletoe infestat...
متن کاملCharacteristics of snags containing excavated cavities in northern Arizona mixed-conifer and ponderosa pine forests
Snags provide an important resource for a rich assemblage of cavity-nesting birds in the southwestern United States. To expand our knowledge of snag use by cavity-nesting birds in this region, we documented characteristics of snags with and without excavated cavities in mixed-conifer and ponderosa pine (Pinus ponderosa Dougl. ex Laws) forest in north-central Arizona. Snags were sampled in 113 s...
متن کاملTree thinning and prescribed burning effects on ground flora in Arizona ponderosa pine forests: A review
Ground flora is an important response variable to monitor after tree thinning and prescribed burning treatments de signed to restore Arizona ponderosa pine {Pinusponderosa P.& C. Lawson) forests. This paper reviews published liter ature on the effects of thinning and burning on ground flora in Arizona ponderosa pine forests in five main categories of research: ground flora biomass, species dive...
متن کاملTree canopy types constrain plant distributions in Ponderosa Pine- Gambel Oak Forests, Northern Arizona
–Trees in many forests affect the soils and plants below their canopies. In current high-density southwestern ponderosa pine (Pinus ponderosa) forests, managers have opportunities to enhance multiple ecosystem values by manipulating tree density, distribution, and canopy cover through tree thinning. I performed a study in northern Arizona ponderosa pine-Gambel oak (Quercus gambelii) forests to ...
