The objectives were to obtain a measure of the amount of Usnea that falls to the forest floor; to determine if there is any difference between usnic acid production in the summer and the fall; to determine if rainwater is an important factor in leaching usnic acid out of lichen material; and to examine the effects of usnic acid upon soil microorganisms and germinating coniferous seedlings.
