Early Forest Succession at the H.J. Andrews My master of science research involved the analysis of a large permanent plot network at the Andrews. By examining the rates and causes of mortality, I was able to draw some conclusions about processes that operate in young forests. My thesis advisor was Charlie Halpern. My thesis committee included Don McKenzie and Doug Sprugel. Research continues. For a PDF of the Thesis, click here. For a PDF of the Ecological Monograph 76:257-275 (2006) article, click here. |

2007 Overstory Sampling The 2007 field crew checks for ingrowth (above). Many of the plots are on steep terrain (left). The red and blue flagging indicates the center of the 250 m2 circular plots. |

Some interesting species and forest dynamics: an old-growth Pseudotsuga menziesii killed by Phaeolus schweinitzii over 20 years ago continues to influence the nearby forest structure, composition and processes. A selection of non-photosynthesizing plants: Allotropa virgata (above right), Pyrola aphylla (lower left), and Eburophyton austiniae (lower left). |
