The Cape May Point Road Census is conducted three times per day from September 1st through October 31st. Counts are made by a single observer driving a car approximately 20-25 mi. per hour along a 5 mile route. All monarchs observed are tallied but no stops are allowed to count specific concentrations. The route passes through a variety of habitats including southern hardwood forest, agricultural field, brackish wetland meadow, suburban neighborhoods, and coastal dunes along the Atlantic Ocean and Delaware Bay. See "Census" tab on main page for map.
To put this years' data in perspective, in Table #1 reading down each yearly column shows the average number of monarchs seen per hour for each of the nine* census weeks. The final cell in the yearly column is the average number of monarchs seen per hour for that year over the entire season.
