The Lamprey Eel Decline project conducted by the Confederated Tribes of
Siletz Indians (CTSI) combined traditional ecological knowledge, scientific research
and geographic information science. CTSI wanted to learn why the Pacific lamprey
(Lampetra tridentata), a culturally and ecologically important species, was declining
in the streams within their native land area. The project included interviewing native
elders, characterizing stream habitat, monitoring water quality, creating a geographic
information system (GIS) and educating tribal members on the cultural and ecological
importance of the Pacific lamprey. Dynamic segmentation, a GIS data structure, was
used to link standard stream survey data on the river unit scale to a base stream
coverage (1:24,000). Dynamic segmentation efficiently associates georeferenced data
to a linear feature, thus allowing the data to be readily assessable on desktop computer
systems. To be more useful to the tribal and local resource managers, it is
recommended that these GIS coverages of aquatic habitat should be used in conjunction with additional data coverages and basic regional models for watershed
analysis and better management of aquatic ecosystems. / Graduation date: 2001
