Hi, we our a couple of Mt. Shasta High School Students doing a Biology
report. We are looking for research/information on trees. Our reports
have to do with planting, thinning and spacing of trees per acre in a
forest. How does thinning effect a trees growth? My report is based
mainly on Pondarosa Pines. And, How does spacing effect a trees growth?
If you could send us some information we would really appreciate it.
Thanks a lot.
