I'm not entirely sure what to do with the equations. Water stress is low for Zoar Valley, so you could try changing the value so that it is smaller then .4 or if that makes it worse experiment and try a larger number until the equation works. Since its very difficult to inquire about these things to the creators of the simforest program, that is what i would do. Perhaps if you can get it to work using a different value, we can figure out the meaning of the value itself or perhaps there is a problem somewhere else in the equation. I also suggest raising the amount of available light, if I understand the previous blog entry correctly. We may be underestimating it far more then we thought. If the equipment was available, it would be best to find the available light ourselves, but maybe I can find a value from a study done on a similar old growth forest.

Regarding the excel file, I have looked at it and it does not have data for 2006. Soooo i will use the newest one I have, to create the new site quality table. I am also in the process of emailing the site quality table I have already created and send that along as well.
