Experimentally evaluating effects of postfire drought on establishment, growth and survival of two widespread western conifer species; lodgepole pine and Douglas-fir
This research seeks to understand how drought following wildfires affects the establishment of two widespread Rocky Mountain tree species, lodgepole pine and Douglas-fir. In Yellowstone National Park, warming, drying conditions are leading to increased frequency of severe wildfires that kill existing trees and trigger regeneration of the forest. These trends are expected to continue. Many tree species in Yellowstone are well adapted to fire. Yet, early and abundant seedling establishment after fire is critical for forests to recover. Tree seedlings are particularly sensitive to drought, and evidence suggests that sufficiently dry postfire conditions could cause widespread tree-seedling mortality, with ecological consequences that may last decades. This research will determine how seedlings from two tree species respond to drought conditions expected in the mid-21st century and will identify the physiological mechanisms that drive seedling response to dry conditions. The results of this study will advance understanding of how forests in the western United States will respond to environmental change over coming decades and provide useful information for western land managers who are grappling with increased wildfires.

Snowshoe Hare Mark-Recapture Trapping Data from western Montana Summer 1998-2018
These data were collected over 21 years from 1998-2018 with trapping primarily occurring from May-August. Snowshoe hares were trapped at 16 different girds spread across two regions (Tally Lake and Seeley Lake). Seeley Lake (Lat. = 47.2degree, Long. = -113.4degree) and Tally Lake (Lat. = 48.5degree, Long. = -114.8degree) are approximately 175 km apart and span similar elevations (approximately 1500-1900 m.a.s.l.). Both areas are managed by the US Forest Service (USFS) with a history of multiple use including timber production and are dominated by moist, coniferous forests of Douglas fir, western larch, subalpine fir, lodgepole pine, Engelmann spruce and Ponderosa pine with a herbaceous understory. Snowshoe hares were trapped during the summer using live-traps. We marked all hares greater than 500g with a unique numbered ear tag. We weighed all hares, determined sex, measured right hind foot (RHF) length and determined breeding status. Only adult hares (weight greater than 700g and RHF greater than 10cm) are included in this dataset.
Co-occurrence of in-stream nitrogen fixation and denitrification across a nitrogen gradient in a western U.S. watershed, 2015 - 2016
This data was collected as part of the NSF CAREER Grant DEB 14-51919 to Amy Marcarelli to evaluate if nitrogen fixation and denitrification co-occur in streams across a gradient of nitrate concentrations. This data was collected during summer 2015 and 2016 in the Portneuf River watershed near Pocatello, ID. In summer 2015, rates of nitrogen fixation were only measured on rock substrate and denitrification only on sediment substrate. In summer 2016, both process rates were measured on both rock and sediment substrate to more accurately capture variation in rates.
Effect of thinning pole stands on soil processes in southern Oregon, central Coast Range, and central western Cascades of Oregon (1994-1995 BLM Study)
This study was conducted in different regions to determine if climatic regimes alter the effects of thinning pole stands. Forest managers are currently faced with increasingly complex demands in designing sulvicultural approaches that fulfill the need to maintain and in some cases, enhance forest health. As mature and old-growth forests with their high degree of structural heterogeneity are replaced by younger plantations with much simpler structure, there is concern that key habitat components are being lost for a number of plants and animals. A silviculture technique that could be used to increase the structural complexity of young stands to thin them; encouraging the development of higher structural complexity. The main purposes of this study is to determine how thinning pole stands influence below-ground processes. The central research question was whether or not this manipulation brings soil characteristics closer to those found in old-growth forests; in essence, accelerating the onset of old-growth-like characteristics via forest management.
Vertebrate-habitat relationships: Logistic regression models predict probability of occurrence of bird and small mammal species in western Oregon
Logistic regression models predicting probability of occurrence of bird and of small-mammal species were produced using animal-habitat data sets from throughout western Oregon (Garman and Cole 1999 - Vertebrate Habitat Relationships Data Bank (VHRDB), Report to Coastal Landscape Analysis and Modeling Study). Regression coefficients, variables, and metrics related to model predictions are provided here under Entity 1, and in VHRDB as VERTLOGR.
Archival records of fire history, 1910-1977, central western Cascades, Oregon
Historical wild fire records for the central western Cascades of Oregon are summarized here for the period from 1910 to 1977. Data records are obtained and summarized from historical statistical reports that were generated by the U.S. Forest Service and exist in various forms including fire maps, summary tables, and individual fire reports. The location, cause of the fire, its size class, and the source of information regarding each fire are included.
Comparisons among five canopy-cover estimating methods in five Douglas-fir/western hemlock structure types in the western Oregon Cascades
Estimates of forest canopy cover are widely used in forest research and management, yet methods used to quantify canopy cover and the estimates they provide vary greatly. Four ground-based techniques for estimating overstory cover -line- intercept, spherical densiometer, moosehorn, and hemispherical photography-and cover estimates generated using the Forest Vegetation Simulator (FVS) were compared in five Douglas- fir/western hemlock structure types in western Oregon. Differences in cover estimates among the ground-based methods did not depend on the structure type in which they were measured (p=0.33). As expected, estimates of cover increased and within-stand variability decreased with increasing angle of view among techniques. However, the moosehorn provided the most conservative estimates of vertical-projection overstory cover. The FVS-generated cover was consistently lower (by up to 44%, 17% on average) than the ground-based estimates and is not advised as a substitute for ground-based measures in these forest types. Regression equations are provided to allow conversion among canopy cover estimates developed with the four ground-based methods.
Potential rapidly moving landslide hazards in Western Oregon, clipped to Andrews Experimental Forest, 1999 to 2002
Landslides are a serious geologic hazard, threatening public safety, natural resources, and infrastructure, and costing millions of dollars for repairs each year in Oregon. This map of areas where rapidly moving landslides pose hazards in western Oregon is part of the State's attempt to protect lives and property. The overview map delineates zones that are prone to landslide hazards, especially rapidly moving landslides. These zones provide information to local governments about property that might require more site-specific evaluation. The map is in digital format and was produced with data at a scale of 1:24,000 (1 in. = 2,000 ft). Creation of the map involved the use of Geographic Information System (GIS) modeling, checking and calibrating with limited field evaluations, and comparing with historic landslide inventories. The extent and severity of the hazard posed by rapidly moving landslides varies considerably across western Oregon. In general, the most hazardous areas are mountainous terrains, which are usually sparsely populated, especially drainage channels and depositional fans associated with debris flows. Where hazard areas intersect with human development, use of the map can help to assess the risk and prioritize risk-reduction activities. Various options are available to reduce the risk of landslide losses. Risk-reduction activities can include engineering solutions, public education, warning systems, temporary road closures and evacuation, land use regulation, and many other options. Although this project addresses a range of rapidly moving landslides, this map is not a compilation of all possible landslide hazards.
Huslia Fire Ecology Workshops: Fire effects on the ecology and people of the Koyukon Region in the western Interior of Alaska
These reports summarize workshops describing fire effects on the ecology and people of the Koyukon Region in the western Interior of Alaska. The first report summarizes all three workshops and is an oral history of indigenous burning in this part of Alaska. The major effect of fire on people is to reduce access by burning trapping cabins and toppling black spruce trees across traplines. Moreover in summer, the brush is so dense that access is difficult and game is impossible to see. Smoke from wildfires is a serious health problem in some years. Burned areas have a colder microclimate than unburned areas, causing both people and animals to avoid them. The second report centers on the final workshop with primary emphasis on the impacts on the community of Huslia. Fire has several important effects on the residents of Huslia. Fire fighting wages are an important source of income and a source of cross-generational mentorship. Wages are important in paying bills and in buying snow machines, ammunition and boat gas for subsistence activities; fire-fighting wages also have some negative effects through purchase of drugs and alcohol. Local residents feel largely disempowered in decisions related to fire management both because of insufficient opportunities for jobs on fire crews and because decisions about whether fires are suppressed or not are made largely without village input.
Urban heat island conditions experienced by the Western black widow spider (Latrodectus hesperus): extreme heat slows development but results in behavioral accommodations
Herein lies data on urban h eat island conditions for black widow spiders across the CAP study area. It also includes data on the development speed and behavioral responses of spiders reared in the lab at these UHI temperatures. The urban heat island (UHI) effect describes the capture of heat by built structures (e.g. asphalt), resulting in elevated urban temperatures. The UHI is a well-studied phenomenon, but only a handful of studies have investigated trait-based shifts resulting from the UHI, and even fewer have attempted to quantify the magnitude of the UHI experienced at the microclimate scale. Here, using a common urban exploiter, the Western black widow spider (Latrodectus hesperus), we show that the UHI experienced by spiders in July in their urban Phoenix, AZ refuges is 6 degrees C hotter (33 degrees C) than conditions in the refuges of spiders from Sonoran Desert habitat outside of Phoenix-area development (27 degrees C). We then use this field microclimate UHI estimate to compare the development speed, mass gain and mortality of replicate siblings from 36 urban lineages reared at temperatures that reflect urban and desert habitats. We show that extreme heat is slowing the growth of spiderlings and increasing mortality. In contrast, we show that development of male spiders to their penultimate moult is accelerated by 2 weeks. Lastly, in terms of behavioral shifts, UHI temperatures caused late-stage juvenile male spiders to heighten their foraging voracity and late-stage juvenile female spiders to curtail their web-building behavior.
Survey of the impacts of an invasive grass (Microstegium vimineum) on soil C and N dynamics in western North Carolina
A survey of soil carbon, nitrogen, plant, and litter decomposition dynamics was conducted along a land-use gradient extending NW from Asheville, NC in the French Broad River Watershed. We selected 12 forest sites between 580 and 780m in elevation. Within each site, there were four paired invaded-uninvaded plots (48 pairs; 96 plots). Invaded plots contained populations of Microstegium vimineum. Soil C pools, soil N pools and transformations, plant community dynamics and litter decomposition rates were quantified in each plot.
