Development of tree height and diameter growth equations for mid-Willamette Valley Douglas-fir

Creator:

Ritchie, Martin W.

Abstract:

Equations for predicting height growth, basal area growth and diameter inside bark are presented for Douglas-fir. Basal area growth equations for grand fir are also presented. The growth models were developed for use in an individual tree/distance independent growth simulator. Various model forms and measures of competitive stress were compared...

Disaggregative and individual-tree growth models in theory and application

Creator:

Ritchie, Martin W.

Abstract:

Disaggregative and individual-tree/distance-independent modeling methods are compared and contrasted. Differences between the two are related to differences in functional and apparent resolution and may be illustrated using aggregation theory. When considering models of different levels of resolution describing a given phenomenon, invariance with respect to the aggregation implied (symmetry) may...
