Here's a list of current and past projects, beginning with the most
recent studies (some of which are not yet final). The final reports
(70-100 pages), 1-2 page summaries, and questionnaires are available as
pdf files (if a link is visible for that document). The pdf for some
recent reports exceeds 1 MB.
There are 5 pages of projects. To find a park study, click on the page
links below or enter a query in the search box. NOTE: Due to a
significant methodology change made in 1988, data from the pre-1988
studies cannot be compared with studies from 1988 on.
