Tree growth and mortality measurements in long-term permanent vegetation plots in the Pacific Northwest (LTER Reference Stands)

<section><para>To examine the rates of succession,and measure mortality and growth in representative forest types in the Pacific Northwest. To examine the structural dynamics of mature and old growth forests. This study examines the size, location, vigor, growth and regeneration of trees with the objective to provide baseline information about different habitats for comparisons. The sites also serve as research locations where measurements of eco-system processes can be taken.</para></section>
