Alana Edwards

Alana has been passionate about butterflies since the mid-90’s when she and her mom started butterfly gardening. Along with friend, Kathy Malone, they founded the first chapter of NABA in Florida in 1996. Alana has been very involved with NABA ever since, attending all of the biennial meetings except the very first one. Alana started leading tours for Sunstreak in 2000, and loves taking tour participants off the beaten path to find the rare and endangered butterflies of south Florida and the Keys. Alana obtained a master’s in Environmental Science in 1998 – her thesis was on The Effect of Time-Since-Burn on Butterflies in a Pine Flatwoods. When Alana isn’t chasing butterflies, she works as Education and Training Coordinator for FAU’s Center for Environmental Studies. She lives in Delray Beach with her two fur children, felines Carmella and Niko.
