Regeneration Model

Introduction

Forest regeneration models are difficult. There are good models out there but they work well for certain forests, species and silviculture. This project is to locate well respected and documented forest regeneration models that can be implemented in Assisi Forest. Anyone interested in regeneration modeling is welcome to join the discussion.

About Assisi Models

Current Assisi Regen Models

Currently only the FVS sprout model has been implemented. Other regeneration response such as seedlings are not automatic: then must must be scheduled through Planting actions. FVS small tree growth models have also been implemented in Assisi.

Volume Calculation

Assisi supports a a large number of ways to calculate volume. This study is a discussion of what the options are and how volume is calculated. First an overview...

The volume in trees has historically been calculated using volume tables, volume equations or using tree taper. Assisi mostly uses the terms Volume Tables and Volume Equations to mean whole tree volume rather than the volume of logs. Assisi uses the term Log Segmenting to mean using taper models to calculate diameters at any point along the tree and therefore the volume of individual logs. The volume of logs is of course calculated using an equation, but for organizational purposes, Assisi groups volume calculate into these three types.

Volume Tables

Volume Tables are tables of tree volume by species, DBH, height and often form class. The values were derived from field studies and were put into this form for…
