According to Lisa Dettlinger, program director at Louisville Grows, Louisville loses around 50,000 trees from its canopy each year, which means there is a constant need to replace and restore what has been lost. “You want a tree canopy of about 40-50 percent. Most of the neighborhoods we work in, the tree canopy on the average is 16-19 percent,” Lisa says.
