Gorillas living under human care don’t always have as many climbing opportunities as their cousins in Africa, so Whole Trees is proud to have designed, engineered, fabricated and installed an all natural climbing structure for the gorilla families at The Philadelphia Zoo, to help them feel more at home. Built from Black Locust and White Oak, and engineered connections by Engineering Ventures, these branching columns will stand the test of primate play and offer hours of fun for our hairy cousins. We couldn't be happier.
