Protecting water quality in Cayuga Lake and in its tributaries can be enhanced by teaching watershed residents and landscapers IPM—ways to manage lawns and gardens with alternatives to chemical pesticides. Through this joint project with the City of Ithaca, we created the first interpretive IPM walkway in the country, located in a downtown park that borders a stream. Along the walkway we planted pest-resistant shrubs, trees, perennials, and annuals, and erected five outdoor signs that teach visitors how to reduce pesticides in their homes and gardens. We invited the community to an educational event in the park and tested the effectiveness of the signs. Forty-two visitors took a pre-test, then walked the trail, read the signs, and took a post-test. Eighty-nine percent of the respondents with incorrect answers improved their scores. Our results indicate that visitors who weren’t familiar with IPM concepts were able to gain those concepts by reading the interpretive signs. We created a free booklet calle Teaching in Conley and informed local teachers about its availability.
