Margaret Carreiro, PhD
and Book Club Co-Chair

Margaret Carreiro earned her PhD in Botany from Univ. of Rhode Island.  She taught in UofL’s Biology Dept. from 2001 until retiring in 2018.  Her research focused on plants and decomposer organisms, including their responses to fossil-fuels combustion and invasive species.  Her Ecology courses included climate change, its causes, impacts and solutions.  Believing faculty should engaged with their communities, Dr. Carreiro wrote the Urban Forestry section of the Louisville's Climate Change Action Plan Task Force's 2008 report to the mayor, and the Louisville Tree Board's guidelines for the first local tree-canopy assessment and for continued urban forest management.  Because natural areas cannot alone conserve native species, several LCAN videos feature Margaret, inspiring others to turn their yards into native species conservation areas.
