BiographyJonathan M. Lehrer is native Long Islander with a passion for plants and a desire to share his knowledge by educating students and the general public. He is a member of the full-time faculty of the Department of Urban Horticulture and Design at Farmingdale State College since 2007 and in Fall 2015 assumed the role of department head. In addition to his duties at the College he serves on several long island committees that address the invasive plant issue and the selection of superior plant alternatives. Dr. Lehrer also enjoys lecturing publicly and writing on topics related to contemporary horticultural challenges.
Research/PublicationsDr. Lehrer led the efforts of colleagues (2012-2015) to develop a rigorous scientific protocol to evaluate the invasive potential of cultivars. This novel approach has been adapted by both the Suffolk County Legislature and the NYS Department of Environmental Conservation to inform legislative decisions.
