Bonanza Creek LTER: Hourly Evaporation measurements at Core Sites from 1988 to Present in the Bonanza Creek Experimental Forest near Fairbanks, Alaska

This study is a survey of the vegetation of the 35 control sites in Bonanza Creek LTER. The 35 sites represent replicates each of six successional stages of primary succession on the floodplain of the Tanana River and four stages of succession uplandsas well as a few recently burned sites. Data include percent cover of all species and count based on twenty 1 m2 or 4 m2 plots. Plots in young stages of succession were remeasured every 1 to 2 years; those in older stages every 3 to 5 years. Some information on biomass in these stages is available. Although most sites were established in 1988 some sites have vegetation plots that have been sampled periodically since 1965. 2009 was the last year of sampling using visual estimates of percent cover. In 2007 a new point framing system was developed and is now used for collecting vegetation data from these sites.
