Rapid Assessment of Roadside Habitat for Monarchs: Field Protocol and Datasheet C-5 Percent aerial cover, estimate for the weeds as a group, from the following categories: None Less than 5% 5-9% 10-25% 26-50% 51-75% Greater than 75% Potential Blooming Nectar Plants Many roadside managers wish to characterize sites in a single visit per year, but what is needed is information regarding the availability of nectar for monarchs throughout the year. Therefore, we collect information for all "Potentially Blooming Nectar Plants," wildflowers (forbs)

C-6 Evaluating the Suitability of Roadway Corridors for Use by Monarch Butterflies Milkweed Because milkweed is required for monarch reproduction, the species and number of milkweed plants is important. Estimating the number of milkweed plants in the assessment area makes it possible to estimate the milkweed density, an important metric in monarch habitat descriptions.
