What is stand density and

where does it come from?

New answers for an old question

Stand density

Quantitative measure of tree occupancy

Measure of crowding in tree stands

Applications-Distribute growth

Applications-Manage light penetration

Concept of stand density based on size-density relations

Application is very hypothetical

Experience is mostly consistent with the basic principles

Interaction between species, age, and site quality hamper efforts to empirically verify the theoretical relationships

The underlying basis of stand density – the systematic exchange of tree density for tree size at equilibrium - still lacks a consensus

“Equilibrium” is also an abstract concept

Seminar objective

To walk through a concept map that represents a word model that describes the underpinnings of size-density relationships

Propose a refined definition of stand density

Present a concrete definition of equilibrium conditions for size-density relations
