PROTECTING WISCONSIN'S BIODIVERSITY

Blooming occurs early-July through late-August, fruiting early-August through early-October.

Annual. The optimal identification period for this species is early-July through late-September.

Associated species include Cakile edentula, Corispermum hyssopifolium, Elymus lanceolatus ssp psammophilus, Ammophila breviligulata, Juncus balticus, Prunus pumila, and Artemisia cuadata.

Seaside spurge is found on sandy beaches and dunes along Lake Michigan.

Avoid broadcast spraying of herbicides and use care with spot spraying.

Because this plant is an annual, work may safely be conducted before the plants emerge or after they have developed mature seeds.

Avoid disturbance to shorelines and the forest-beach interface.

Avoid any activities that destabilize the dune, including the use of off-road vehicles, removal of native vegetation, and pedestrian recreational overuse.

Species of Greatest Conservation Need (SGCN) are associated with habitats (or natural communities) and places on the landscape. Understanding relationships among SGCN, natural communities and ecological landscapes help us make decisions about issues affecting SGCN and their habitat and how to respond.

Conservation actions respond to issues or threats, which adversely affect species of greatest conservation need (SGCN) or their habitats. Besides actions such as restoring wetlands or planting resilient tree species in northern communities, research, surveys and monitoring are also among conservation actions described in the Wisconsin Wildlife Action Plan because lack of information can threaten our ability to successfully preserve and care for natural resources.
