Analyzing fire mosaics in temperate coniferous forests with GIS and remote sensing

Creator:: Kushla, John D.
Abstract:: This investigation on fire mosaics addressed several aspects: (1) quantifying the role of terrain variables in fire-related mortality and historical mean fire return interval (MFRI), (2) comparing post-burn Landsat Thematic Mapper (TM) imagery, TM difference imagery, and aerial photo interpretation to map forest survival after wildfire, and (3) to describe...

Development of two coniferous stands impacted by multiple, partial fires in the Oregon Cascades : establishment history and the spatial patterns of colonizing tree species relative to old-growth remnant trees

Creator:: Goslin, Matthew N.
Abstract:: Trees that survive disturbances can form a prominent legacy which may influence post-disturbance successional pathways. The effects of biological legacies on community dynamics is a critical question in ecology. In the present study, I examined two mapped stands in which old-growth remnant trees, survivors of partial fires, emerge above a...

Historic fires in the central Western Cascades, Oregon

Creator:: Burke, Constance J.
Abstract:: The history of fire between 1850 and 1977 in a portion of the Willamette National Forest in-the central Western Cascades of Oregon was documented using historical sources. Three types of records were available: (1) records and writings not primarily concerned with fire but yielding information about fire in context with...

Meadow classification in the Willamette National Forest and conifer encroachment patterns in the Chucksney-Grasshopper meadow complex, Western Cascade Range, Oregon

Creator:: Dailey, Michele Meadows
Abstract:: This study delineates and characterizes the distribution of montane meadows in the Willamette National Forest, identifies encroachment patterns in relation to topographic features and proximity to trees in the Chucksney-Grasshopper meadow complex, and examines tree species and age distributions in relation to distance from forest edges or isolated tree clusters...

Buffer strip dynamics in the Western Oregon Cascades

Creator:: Sherwood, Kim
Abstract:: Although buffer strips have long been used as a protection tool when logging near streams, long-term studies investigating buffer strip dynamics are rare. Steinblums et al. (1984) inventoried 40 buffer strips 1 to 15 years old in the western Oregon Cascades beginning in the summer of 1975. Numerous site and...

Forest vegetation and fuel dynamics following stand-replacing wildfire, re-burn, and postfire management in the Siskiyou Mountains, Oregon

Creator:: Donato, Daniel C.
Abstract:: Following high-severity fire, forest succession may take alternate pathways depending on the pattern of the fire and any secondary disturbances during early stand development, with lasting consequences for ecosystem function. The objectives of this research were to quantify: (1) early postfire regeneration as influenced by the spatial pattern of a...

Temporal and spatial variability of historic fire frequency in the southern Willamette Valley foothills of Oregon

Creator:: Robbins, Danielle
Abstract:: A crossdated fire history was reconstructed for a 1562 km2 area in the southern Willamette foothills of Oregon, using fire scars and tree origin years from twelve sites. The purpose of this study was to determine fire frequency for each site and to quantify temporal and spatial variability of fire...

Overstory composition and stand structure shifts within inter-mixed ponderosa pine and lodgepole pine stands of the south-central Oregon pumice zone

Creator:: Shuffield, Chaylon D.
Abstract:: Ponderosa pine (Pinus ponderosa) and lodgepole pine (Pinus contorta var. murrayana) forests of south-central Oregon have been extensively researched over the last century. However, little information has been reported on overstory composition and stand structure shifts associated with fire exclusion within inter-mixed ponderosa pine and lodgepole pine stands of the...

Ecological effects of post-wildfire management activities (salvage-logging and grass-seeding) on vegetation composition, diversity, biomass, and growth and survival of Pinus ponderosa and Purshia tridentata

Creator:: Sexton, Timothy Ogden
Abstract:: Salvage-logging and artificial seeding of grass following wildfire are common practices in coniferous forests of the western United States, yet few studies have quantified the ecological effects of these post-fire activities. The effects of post-wildfire salvage-logging and grass-seeding on vegetation composition, aboveground biomass, and growth and survival of Pinus ponderosa...
