Stand Dynamics of the Spruce-Fir Forest in East-Central Arizona
New functions are presented for spruce-fir survivor growth, ingrowth, and mortality using a data set of Continuous Forest Inventory plots exclusively from the spruce-fir forest type in east-central Arizona. The individual tree diameter squared growth model is validated at the tree and stand level with an independent data set. Individual tree mortality is modeled for any projection interval with a logistic function. Ingrowth dynamics is modeled at three levels of resolution; the stand level, species level, and the diameter class level. Ingrowth trees are distributed to diameter classes using the Uniform distribution. West. J. Appl. For. 12(2):55-61.

More about this publication?
- Each regional journal of applied forestry focuses on research, practice, and techniques targeted to foresters and allied professionals in specific regions of the United States and Canada. The Western Journal of Applied Forestry covers the western United States, including Alaska, and western Canada; WJAF will also consider manuscripts reporting research in northern Mexico that has potential application in the southwestern United States.
