This enclosure has a lot of real vegetation in it, without resorting to added poles, fences or other fake contraptions. A few dead logs and harnesses for the apes to sleep in, but the trees add a sense of realism to the exhibit. This is probably one of if not the best orang habitat in any zoo in North America.
The exhibit is continually lush and green, but then Seattle does receive 40 inches of rainfall each year. The orangs do not destroy the trees, and there is not any hotwire around any of the foliage.
The foliage is so overgrown that it would take a lot of work for the orangs to fully destroy the trees.
Every day of the year, although they often hang out in their covered, indoor area if it is cold and raining. There are 5 orangutans between 2 naturalistic enclosures.
