Hubbard Brook Experimental Forest: Gastropod lichen feeding trials

Herbivory by terrestrial gastropods, particularly Arion sp., can alter lichen communities; however, little is known about this interaction in forests of North America. This data set reports the results of two feeding trials with slugs and snails from Hubbard Brook on seven lichen species. In feeding trials two common lichens, Hypogymnia physodes and Platismatia glauca, were grazed more heavily by both native and non-native slugs than other lichen species.
