Compost mounds at Miami's Metro Zoo

When it comes to compost piles, Metro Zoo is not kidding around...in a remote field on the grounds of the zoo, Randy has several piles of composting elephant dung as well as other piles which contain mixtures of mulch, tree branches, leaves, and dung from various herbivores at Metro Zoo; it's a highly organized operation; according to Randy, during the breakdown phase, the mounds can reach temperatures between 120-160 degrees farenheit; Randy knows a mound is ready for use as compost when it reaches a temperature closer to 90 degrees farenheit
