Upper Columbia Basin Network Aspen Monitoring Annual Report 2009: City of Rocks National Reserve (Ciro): Natural Resource Technical Report Nps / Ucbn / Nrtr?2010/386 National Park Service

This annual report details the status estimates obtained during the third year of monitoring panel 3 during the field season 2009 in CIRO where 45 plots were sampled in 8 stands. Summary data from 2008 is also included in this report to provide a summary of the park data for CIRO. In addition, the authors detected an error in the calculation of aspen and conifer density in the annual report of 2008 (Strand and Bunting 2009), another reason to include corrected 2008 data in this annual report focusing on 2009.
