At Cedar Creek Lactuca canadensis is present in fields of various ages but is rather rare.
The population of Lactuca canadensis plants used in this study was within a 10 X 12 m area bisected by one side of a gopher + deer exclosure.
The population of Lactuca canadensis in field 28 was very localized.
Browsing by deer affected Lactuca canadensis by reducing plant height, causing a change in the morphology of the plant, and, based on the number of flowering heads per plant, causing over a 7-fold reduction in reproductive output (Table 1, flowering heads per plant).
