Plants

For the first time at Big Cypress National Preserve, researchers used tree rings (growth rings) to study tree ages and which environmental/climate factors influence tree growth. One finding was that standing water levels—in this landscape shaped by water—are key. Researchers were also reminded that “you can’t always judge a book by its cover,” as some of the smallest trees measured were also the oldest.

Two closely related plants grow near one another in Big Cypress National Preserve. One type is federally threatened, and the other is not. In other areas they can be distinguished from one another by the fuzziness of their leaves, but in Big Cypress this does not hold true. So how do botanists tell them apart for monitoring and stewardship? Still by their leaves, but at a microscopic level. Read our story to learn more.
