A permanent vegetation plot illustrating rapid changes in species composition during the first 5 yr of succession. Plots were established
in 1962 (prior to timber harvest) and continue to be sampled as part of the Long-term Ecological Research Program
at the H.J. Andrews Experimental Forest (http://www.fsl.orst.edu/lter/).
 
1 year after broadcast burning
  
2 years after burning: dominated by Senecio sylvaticus
 
3 yr after burning: dominated by Epilobium angustifolium
  
5 years after burning: dominated by Epilobium angustifolium
 and Ceanothus velutinus (to the right)
