  • SIGDOC - Envisioning mobile apps for audio description: exploring universal design of National Park Service brochures
    Proceedings of the 33rd Annual International Conference on the Design of Communication - SIGDOC '15, 2015
    Co-Authors: Brett Oppegaard, Thomas Conway, Megan Conway
    Abstract:

    Unigrid" design specifications created by Massimo Vignelli have provided the standards for the layout of paper brochures at U.S. National Park Service sites for more than three decades. These brochures offer visitors a familiar analog presentation of visual information, blending text, photographs, maps, and illustrations. These materials, however, are not accessible to people who are blind, have low vision, or a print disability. The National Park Service for decades has been challenged -- by requirements and principle -- to offer alternate formats that provide equivalent experiences and information of these print materials. In other words, people who are blind or visually impaired should have access to a "brochure" experience, too. This exploratory study, funded by the National Park Service, takes a new approach to this long-term problem by conducting a content analysis of current Unigrid brochures to determine their fundamental components, found in practice. This components-based approach is intended to provide clear pathways for cross-modal translation of the printed material into audio-described media, which then, can be efficiently distributed via mobile apps, as an extension of these original components.

  • Whitebark Pine in the Northern Cascades: Tracking the Effects of Blister Rust on Population Health in North Cascades National Park Service Complex and Mount Rainier National Park
    Forests, 2018
    Co-Authors: Regina M. Rochefort, Shay Howlin, Lacey Jeroue, John R. Boetsch, Lise P. Grace
    Abstract:

    Whitebark pine (Pinus albicaulis Engelm.) is a key component of subalpine and alpine ecosystems in the northern Cascades. The species’ survival is threatened by white pine blister rust, mountain pine beetle, fire exclusion, and climate change. We monitored whitebark pine in permanent plots in two National Parks three times between 2004 and 2016. The proportion of live trees showing evidence of blister rust infection increased in North Cascades National Park Service Complex from 32% in 2004 to 51% in 2016 and from 18% to 38% in Mount Rainier National Park. Mortality increased from 7% to 21% in North Cascades National Park Service Complex and 38% to 44% in Mount Rainier National Park. The percent of live infected and dead whitebark pine increased with south and east aspects and mortality decreased with elevation. Annualized mortality rates calculated for the entire study period were 1.5% in Mount Rainier National Park and 2.3% in North Cascades National Park Service Complex. Although these rates decreased between the first time period (2004–2009) and the second time period (2009–2016), the prevalence of infected and dead whitebark pine increased across all Park landscapes over time and increased in smaller diameter whitebark pine trees.

    Abstract:

    Whitebark pine (Pinus albicaulis Engelm.) is a key component of subalpine and alpine ecosystems in the northern Cascades. The species survival is threatened by white pine blister rust, mountain pine beetles, fire exclusion, and climate change. Trees were monitored in permanent plots in two National Parks three times between 2004 and 2016. The proportion of trees showing signs of blister rust infection increased in North Cascades National Park Service Complex from 32% in 2004 to 51% in 2016 and from 18% to 38% in Mount Rainier National Park. Mortality increased from 7% to 21% in North Cascades National Park Service Complex and 38% to 44% in Mount Rainier National Park. Annual mortality rates were calculated for three time periods: 2004-2009, 2009-2015/2016, and 2004-2015/2016. Mortality rates, annualized across the entire study period, were 1.47% in Mount Rainier National Park and 2.27% in North Cascades National Park Service Complex; these rates decreased between the first time period and the second, which could reflect blister rust resistance. Signs of mountain pine beetle were rare and limited to a few trees in individual plots. Although reproductive trees were found in most stands, densities were low and regeneration was dominated by subalpine fir.
