The Boston Parks Department has recently turned to a novel idea to help clear poison ivy, oak and sumac: goatscaping. The goats clear unwanted plants and as an added bonus,  make fresh fertilizer (goat excrement) back into the environment. Friday on Boston Public Radio, co-founders Jim Cormier and Elaine Philbrick stopped by — with baby goats Butternut and Birch, the two baby goats, for the  Friday News Quiz.

Taking advantage of Butternut and Birch's visit to our studios, WGBH News reporter Edgar B Herwick III took the opportunity to live-stream a behind-the-scenes exclusive interview with the goat entrepreneurs on the live-streaming site Periscope.
