BRATT, CHARIS C.* AND DANIEL LAHR. Santa Barbara Botanic Garden, 1212 Mission Canyon Road, Santa Barbara, CA 93105. - A comparison of the lichens on deciduous and non-deciduous oaks.
A study was undertaken to determine if deciduous oaks had more lichen
species than non-deciduous oaks. Pairs of trees close by one another
and of the same size were sought in various locations. All of the
lichen species were collected, identified and recorded for each site.
Comparisons were made for each site and for the overall study. Bark
samples were taken from each tree and measure for acidity.
