Integrated watershed management encompasses complex physical and social iss
ues that have impacts on environmental resources. A key aspect of this holi
stic effort is public education. Most researchers and practitioners agree t
hat an informed public is a crucial part of the environmental management pr
ocess. Yet, educational programs that provide stakeholders with information
about physical processes in watersheds are often unavailable. This paper a
ssesses the effect of an education program for residents of the New York Ci
ty watershed. Surveys evaluated certain knowledge levels and attitudes of p
articipants and compared three groups: individuals who utilized the educati
onal materials completely (full users), those who received the materials bu
t did not use them completely (partial users), and watershed residents who
did not receive the educational program (nonrecipients). Full users display
ed a higher level of knowledge concerning specific watershed processes than
did partial users and nonrecipients. In terms of applying that knowledge a
cross linked concepts, however, we observed no significant differences betw
een the three readership levels. Furthermore, partial users engaged in less
evaluation of issues that related to the broader watershed context. The fi
ndings from this project have implications for educational and regulatory i
nstitutions and program development relating to watershed protection.
