Science Wednesday: Mapping Forest “Fuels”
Wednesday, November 19th, 2008
Each week we write about the science behind environmental protection. Previous Science Wednesdays.
About the author: Todd Erdody is a MS student at the University of Washington College of Forest Resources. His work is funded by an EPA Science to Achieve Results (STAR) Graduate Research Fellowship.
Before starting my graduate education in the fall of 2007, I was working as a fire monitor and firefighter in Sequoia and Kings Canyon National Parks in California. I was headed for a graduate program in remote sensing and forestry with a college-funded fellowship and no set thesis topic. I spent a good part of that summer thinking about potential research topics as I ignited prescribed fires and fought, monitored, and mapped wildfires.
I realized that I wanted to build on existing research at the University of Washington to find better ways to estimate canopy “fuels”— small-diameter branches and foliage (leaves) that will burn in a wildfire.
Existing fuels maps are made from coarse-resolution vegetation maps and satellite imagery. By using high-resolution, remote sensing data such as LiDAR (Light Detection and Ranging) and digital imagery, perhaps canopy fuels could be mapped more accurately and efficiently. Through improved fuels mapping, smoke and harmful particulate matter production from wildfires could be more accurately assessed.
Since I was only funded for my first year of graduate school, I was looking for assistance. I was very grateful to receive the EPA STAR fellowship for the 2008/2009 academic year. Aside from helping me in my second year of graduate education and enabling me to focus on my work, it gives me the resources needed to attend a variety of conferences to present my research.
I wanted to focus my research on a fire-prone ecosystem, so I chose to work in the forests dominated by Ponderosa pines in eastern Washington State. I am currently building regression models for canopy fuel metrics and will eventually produce maps of canopy fuel loading. My goal is to be able to use these models in similar forest types throughout the Northwest.
Others have done similar work in the forests of western Washington and, although I am using existing methods, the real difference is that I am creating models in ecosystems that will frequently burn. The applications for this research are far-reaching in terms of both geography and planning. I envision forest managers using high-resolution remote sensing technologies to map fuels more effectively and create maps for use in wildfire and smoke modeling programs.


As a modern day parent, getting my kids out into nature can be a challenge. Even though I take them frequently to the country or on the occasional road trip, finding time to experience nature every day is very hard. Four children, a busy schedule, and living in the suburbs are not the right mix to provide for nature oriented experiences. Still,I carve out the occasional moment to give my kids outdoor experiences, like when I tend to my garden or let them play when I air-dry our clothes, Recently, I accidentally ran a cart over a small snake. Upon finding it, I took my three year-old son to the backyard to show him the dead snake. I ran my fingers over its slimy body and my son felt instant curiosity to know how it felt, and did the same. I told him about what snakes eat and how they hide in the base of the ginger and heliconia plants.
Hoy día como madre exponer a mis hijos a este tipo de actividad, que para mi era tan común, es un gran reto. Aunque suelo llevarlos al campo y a la playa ocasionalmente, hacer tiempo en nuestra rutina diaria para convivir con la naturaleza es difícil. Mi agitado estilo de vida, vivir en los suburbios unido a la crianza de 4 niños no son una receta fácil para obtener experiencias relacionadas a la naturaleza diariamente. Sin embargo trato de buscar esos momentos como cuando vamos a sembrar plantas en el jardín o secamos la ropa al aire libre, ocasión en que los niños exploran abiertamente sus alrededores o como cuando recientemente aplasté una pequeña culebra en nuestro patio. Cuando la encontré llevé a mi hijo de 3 años al patio para que pudiera verla. Al deslizar mis dedos sobre el cuerpo de esta, mi hijo sintió la curiosidad innata de hacer exactamente lo mismo. Aproveché el momento y le hablé sobre ellas y cuanto les encanta esconderse en la base de los jengibres y heliconias del patio.
