Posted by: Kirsten Pisto, Communications These spring days can be such a tease, sunny and bright one minute and then a windy deluge the next, but ohhh the green! Bright shiny blades of emerald appear in magnificent patches across our lawns and meadows, flowers shoot up between cracks in the pavement and all the zoo appears to be bursting with life.

After just a few weeks of spring rain showers and warmer days, the blooming canopy on our 93 acres has changed the landscape considerably. Hundreds of trees, shrubs, and flowers are in full vigor. The thriving green scenery that cloaks the zoo this time of year makes a distinct impression on visitors and residents alike.
