The state of Kansas recently received a NASA EPSCoR grant, which includes a
project to model rural resource systems (http://spot.geog.ksu.edu/~epscor/). The
overall methology is based on remotely sensed datasets in combination with climatic
data and landscape characteristics such as topography, drainage, and soils. Spring,
summer, and autumn imagery from selected years will be the basis for analyzing rural
resources with a special emphasis on identifying vegetation changes related to
climatic events. Within this project, our role focuses on forest cover in the
glaciated region of northeastern Kansas. Remnants of hardwood forest are preserved
particularly along bluffs of the Missouri River valley. Our assumption is that
interannual changes in forest conditions are primarily reflections of climatic
Landsat TM data will provide the necessary spatial and spectral
resolution to examine relatively small forest parcels and to derive vegetation
indices based on visible and infrared reflectivity of active leaves. Detailed
studies will be conducted on forest at Ft. Leavenworth. Ground-based observations
and aerial photos will provide information on forest composition and structure.
Tree-ring samples will be collected as records of forest growth. Many ground-based
observations are available that provide good spatial coverage for climatic variables.
Selected weather stations are St. Joseph and Kansas City in Missouri, and Atchison
and Leavenworth in Kansas. The principal limitation is lack of cloud-free Landsat
imagery for spring and early summer in many years--the wet season. Thus, we have
shifted our focus to three-season imagery for some years (1988 and 1994) and
summer-only imagery in other years (1987 and 1990) for interannual comparisons of
