Data From: Yellow Air Day Advisory Study, Arthur J. Caplan

Browse all Datasets

Using a dataset consisting of daily vehicle trips, PM2.5 concentrations, along with a host of climactic control variables, we test the hypothesis that “yellow air day” advisories provided by the Utah Division of Air Quality resulted in subsequent reductions in vehicle trips taken during northern Utah’s winter-inversion seasons in the early 2000s. Winter inversions occur in northern Utah when climactic conditions are such that PM2.5 concentrations (derived mainly from vehicle emissions) become trapped in the lower atmosphere, leading to unhealthy air quality (concentrations of at least 35 µg/m3) over a span of what are called “red air days”. When concentrations …

Data For Farmland Preservation Study, Arthur J. Caplan, Brent C. Chamberlain

Browse all Datasets

This study fills a gap in cultural ecosystem service (CES) assessment of prime farmland located in peri-urban areas by presenting results from a choice experiment recently conducted in Utah’s Wasatch Front region. The choice experiment was designed to account for heterogeneous effects associated with a wide array of socio-demographic and attitudinal characteristics on household preferences for farmland preservation, including farmland used for the joint production of solar power and agricultural products. We apply a mixed-logit model to our data that controls for preference heterogeneity among Wasatch Front households along two dimensions – at the individual household level and according to …

Data From: Wildfire, National Park Visitation, And Changes In Regional Economic Activity, Man-Keun Kim, Paul M. Jakus

Browse all Datasets

Data from the associated paper. Abstract from paper below:

The visibility, safety, and health effects of seasonal wildfires may affect recreational visits to national parks (NPs), even if fires occur outside of park boundaries. This study statistically quantifies the effect of nearby wildfire on tourist flows to each of Utah's five NPs (Arches, Bryce Canyon, Canyonlands, Capitol Reef, and Zion). Using monthly data from May 1993 to December 2015, we empirically link wildfire activities (measured as monthly area burned within 80 km, 160 km, and 320 km radii) to monthly visits to each national park. Results show that …

Wasatch Front Preventative Capital Study, Arthur Caplan, Ramjee Acharya

Browse all Datasets

We address the issue of optimal investment in “preventative capital” to mitigate episodic, mobile-source air pollution events in Utah’s Wasatch Front region. We calibrate Berry et al.'s (2015) endogenous-risk model using a unique dataset related to the region’s "red air day" episodes occurring over the past decade. Our analysis demonstrates that, under a wide range of circumstances, the optimal steady-state level of preventative capital stock – raised through the issuance of a municipal “clean air bond” that can be used to fund more aggressive mitigation efforts – meets the standard for PM2.5 concentrations with positive social net benefits. We estimate …

Usu Careers In Agriculture, Forestry, Natural Resources, Grades 9-12, Tyson Sorensen, Olivia Horning, Joshua Dallin

Browse all Datasets

These are brochures (three currently have been completed) that were developed as part of this grant to promote AFNR careers among high school-aged students. These brochures were developed with a focus on careers related to Genetic Engineering and Biotechnology. The brochures were distributed to participants of the workshop and with invitations for them to also distribute the brochures to their school's career/guidance counselors. The goal of the brochures is to help students learn about and see the pathway to get to their agriculture, forestry, or natural resources career of interest.

Survey Data From Ecochallenge Workshop, Tyson Sorensen, Kelsey Hall, David Francis, Joshua Dallin

Browse all Datasets

The Borich calculator analyzed the data from the EcoChallenge (Explore) workshop to determine professional development needs of educators for future workshop planning. The calculator takes into account IMPORTANCE and PERCEIVED COMPETENCE of each item and calculates Mean Weighted Discrepancy Scores (MWDS). Those are then ranked and the data shows those results. The survey instrument is attached. The workshop was student-centered but allowed for educational professionals to engage with the materials (Exploring careers in AFNR).

Survey Data From Utah Urban Agricultural Workshop, Tyson Sorensen, Kelsey Hall, David Francis, Joshua Dallin

Browse all Datasets

Forty-two teachers who attended the Urban Agriculture Workshop were surveyed after the workshop to assess the value of various aspects of the workshop and to measure pre-post gains in knowledge, ability, and importance. Also to measure attitudes, subjective norms, perceived behavioral controls, and behavioral intention. Demographics were also collected. Data show the results. Survey Instrument is attached. Scaling varies (see instrument).

Curriculum: Careers In Urban Agriculture (Grades 7-12), Tyson Sorensen, Kelsey Hall, David Francis, Joshua Dallin

Browse all Datasets

Materials were created for school-based agricultural educators (7th-12 grade) to use for students in Utah. This curriculum covers multiple days of instruction but 3-5 (50-minute sessions) days is what it is intended for. Includes a unit plan for the instructor, presentation slides (PPT and PFD), worksheets, and other materials. This curriculum focuses on careers in urban agriculture.

High And Dry: Post-Fire Tree Seedlingestablishment In Subalpine Forestsdecreases With Post-Fire Drought Andlarge Stand-Replacing Burn Patches, Brian J. Harvey, Daniel C. Donato, Monica G. Turner

Aspen Bibliography

Aim: Climate warming and increased wildfire activity are hypothesized to catalyse biogeographical shifts, reducing the resilience of fire-prone forests world-wide. Two key mechanisms underpinning hypotheses are: (1) reduced seed availability in large stand-replacing burn patches, and (2) reduced seedling establishment/survival after post-fire drought. We tested for regional evidence consistent with these mechanisms in an extensive fire-prone forest biome by assessing post-fire tree seedling establishment, a key indicator of forest resilience.

Location: Subalpine forests, US Rocky Mountains.

Methods: We analysed post-fire tree seedling establishment from 184 field plots where stand-replacing forest fires were followed by varying post-fire climate conditions. Generalized linear …
