PROJECT ABSTRACT Colorado Plateau Cooperative Ecosystem Studies Unit (Cooperative Agreement # H1200-004-0002) Park: Mesa Verde National Park Project Title: Phase Two: Fire History and Vegetation Change at Mesa Verde National Park, Colorado Funding Amount: $16,000 CPCESU Partner Institution: Northern Arizona University Principal Investigator: R.

Charcoal analysis has been conducted only on one core in Prater Canyon, which spans the last ca. 4,800 years. Another drill core collected from Morefield Canyon has a bottom date of 8,700 calendar years, thus spanning most of the Holocene. Using funding provided in the original NPS cooperative agreement, NAU has been analyzing the pollen from this core to reconstruct longer-term vegetation changes in Mesa Verde. However 1 the original budget does not have enough funds to conduct any additional charcoal analysis on the Morefield core sample. This phased project would allow for that work to be conducted in conjunction with the original project. Key Words: Holocene, sediment, core, charcoal, pollen, fire history 2
