Dispersion of fluorescent powders, dyes and spores from a clearcut area into and within a 45-year old Douglas-fir forest was studied under various meteorological conditions. A total of 111 rotorods samplers were used to trap the tracers within a canopy volume of 20 m height, 210 m width and 270 m length. Wind speed, direction and air temperature were monitored on five towers on a line perpendicular to the forest wall. Twenty-four multiple location releases were made during 1968 and 1969. Part 1 describes the experimental site, procedures and methods, Part II contains data collected and Part III results, discussion and conclusions. Author
