Life in tall trees
Reference type: Journal Article
A study was made of the community of plants and animals in the upper part of the canopy of a 450-year-old stand of Pseudotsuga menziesii (ca. 200 ft high) in western Oregon. Results showed that the community formed a unique ecosystem of considerable complexity (comparable in many respects to communities found on the forest floor) that may act in an old-growth stand, as the main pathway for the provision of N to the trees. Some of the lichens found were very susceptible to smog damage. Special climbing equipment was designed for the study [cf. FA 34, 6375].
