Characteristics 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 کاملA 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 کاملPlant recruitment in a northern Arizona ponderosa pine forest: Testing seed- and leaf litter- limitation hypotheses
Seed availability and leaf litter limit plant establishment in some ecosystems. To evaluate the hypothesis that these factors limit understory plant recruitment in Pinus ponderosa forests, I conducted a seeding and litter removal experiment at six thinned sites in the Fort Valley Experimental Forest, northern Arizona. Experimental seeding of four native species (Penstemon virgatus, Erigeron for...
متن کاملPonderosa pine restoration and turkey roost site use in northern Arizona
Ecological restoration of ponderosa pine (Pinus ponderosa) forests in the southwestern United States is a relatively new, adaptive management practice that potentially alters wildlife habitat during and immediately after restoration treatments. To determine whether restoration treatments affected Merriam’s wild turkey (Meleagris gallopavo merriami) use of roost sites, we relocated 91 of 120 tur...
