One Year After First Outplanting of CREW Propagated Ferns in Florida

Florida has more fern species than any other state in the mainland United States, and CREW is working with partners at Fairchild Tropical Botanic Garden in Miami, Florida, to help propagate several of the most endangered from rapid urbanization and habitat loss.

The gridscale maiden fern, Thelypteris patens, is a large, beautiful fern that can reach over five feet in height. The patens variety is known only from the pine rockland habitat in Miami-Dade County and is listed as endangered in Florida. The population in one particular preserve declined to a single plant, which died in 2013.

However, before it died, researchers from Fairchild Tropical Botanic Garden collected spores from that plant and sent them to CREW’s Plant Lab here at the Cincinnati Zoo & Botanical Garden. CREW plant scientists germinated the spores in test tubes (in vitro) to produce tiny gametophytes, which represent the first stage in the fern life cycle.

These were then nurtured further in culture to produce sporophytes, which represent the second stage of fern growth and are the plants we normally think of as ferns. The sporophytes were acclimatized to soil at CREW, and then over 200 of these plants were sent to collaborators at Fairchild Tropical Botanic Garden where they were grown further in their greenhouses.

Finally, in May and June of last year, over 150 of the ferns propagated at CREW were outplanted back into the preserve where the species had been extirpated.

The plants are being monitored by Fairchild Tropical Botanic Garden. As of February 2015, the plants have had an 89% survival rate.

Moe, the Two-toed Sloth, and Her Keepers Help Save Sloths in Costa Rica

Do you know Moe? You should! She is the star of the Discovery Forest exhibit in our Education Center. As a two-toed sloth, Moe spends her days hanging out in her favorite tree. While she does rest a lot (she is a sloth, after all), Moe can be quite active at times and she is very curious.

Moe has become a favorite with the thousands of kids and families that participate in Education programs and camps. You can’t come and go to Summer Camp without passing by to say hello and good-bye to Moe. At the end of the day, Moe climbs down a special ladder made just for her into the arms of one of her keepers, who carries her to a behind-the-scenes suite for the night.

These days, Moe is doing more with her celebrity status beyond inspiring our guests. She and her keepers are helping to save sloths in the wild. Between April and October, guests can schedule a private, up close 30-minute encounter with Moe and her keepers. A portion of the proceeds from the ‘Moe’mentous Sloth Encounter support The Sloth Institute Costa Rica (TSI) and its mission to ensure a peaceful coexistence between sloths and people.

The Sloth Institute (TSI) was established in August of 2014 by Sam Trull and Seda Sejud to enhance the well being of captive and wild sloths through research and education. In collaboration with Kids Saving the Rainforest (KSTR), TSI helps to rescue, rehabilitate and release the sloths of Manuel Antonio, Costa Rica. In the area near Manuel Antonio National Park, one of Costa Rica’s smallest yet most popular tourist destinations, roads and development have fragmented the natural forest habitat, increasing the threats to the very wildlife people come to see. The most common injuries to sloths are electrocutions from touching electrical wires and orphans separated from their mothers. Sloths are also vulnerable to vehicle strikes and dog attacks when they descend from the trees. In addition, TSI helps KSTR hand-rear baby sloths that are orphaned because the mother abandoned them or the mother was injured or killed. Sloths can be very difficult to raise due to their sensitivity to infection and incomplete information on what wild sloths need to survive.

When possible, the goal is to rehabilitate and release the sloths that are healthy and capable enough to survive and thrive again in the wild. In order to monitor each individual’s success post release, TSI plans to fit each sloth with a tracking device that will allow them to be monitored post-release and contribute to knowledge about sloth ecology and how to successfully raise and release orphaned and injured sloths.

TSI is beginning its first release project of 2 two-toed and 2 three-toed sloths. The release process involves selecting and obtaining permits for an appropriate forested area for the release that is safe from development, electric wires and cars. Once a site is secured, the sloths will be transferred from the KSTR rescue center to a soft-release enclosure in the forest to let them get used to their new environment. During this time, TSI will provide leaves from the forest to get the sloths more used to the diet found at the release site while still supplementing them with captive food. After about a month, TSI will open the door, allowing the sloths access to the surrounding forest. They will be able to choose when to explore the outside world. This “soft release” gives the sloths as much time as they need to get used to their new environment and learn how to find food before going off completely on their own, which is the most appropriate method for hand-raised orphans that require a lot of maternal investment.

With funding from the Cincinnati Zoo, TSI was able to purchase four of the VHF tracking collars for this project. Fitted with the collars, the sloths can be tracked around the clock to collect behavioral data, locational data and health status information.  Simultaneously, TSI will also track wild sloths for comparison and to provide parameters for evaluating the success of the release.

Furthermore, TSI will also start a long-term field station for studying wild sloths in Manuel Antonio. They hope to learn more about sloth ecology in this region of Costa Rica, including information on diets, home range, carrying capacity, health status and social structure.

Keep up with the latest happenings at TSI through its Sloth Diaries blog, and consider supporting sloths in the wild by booking your own Sloth Encounter at the Zoo. And next time you’re at the Zoo, be sure to stop into the Education Center to say hello to Moe.

Saving the Kea

Hello! My name is Ke’Yasha Lumaine and I am a senior at the Zoo Academy. That’s right, the ZOO ACADEMY! I have been fortunate enough to actually go to school at the Cincinnati Zoo & Botanical Garden my junior and senior years of high school. It has been an amazing life experience. There is a particular memory at the Zoo Academy that I will always think of fondly – my first encounter with the kea.

During my senior year, I had the chance to do a lab rotation in the Aviculture (bird) department. It was the coolest experience that I have had with any department at the Zoo. Lab is where we spend two hours every day taking care of animals or maintaining Zoo grounds. I’ve had lab in Night Hunters, Maintenance, Commissary, Conservatory, Manatee Springs, Reptile House, Education and Education Interpretive Collection, yet no lab compared to the Aviculture department. At the time of my lab rotation, I had the chance to go into the Flight Cage which has kea, lorikeets, pigeons, and geese that are free to fly around the whole exhibit. To me, the most exciting birds in the exhibit were the kea. When Kim (an Aviculture keeper) and I walked into the enclosure, they all came wobbling towards us. They can look very intimidating with their long, sharp beak, strong claws and are pretty big in size for a parrot. I was a little uneasy about this at first but I felt sort of safe since Kim was there. They just swarmed around and played with us, climbing on my boots and following me around. They were like puppies, just with large beaks and wings! After my lab rotation, I learned that kea are the world’s only alpine parrot, that they live in the mountainous regions of South Island, New Zealand and that they were almost hunted to their extinction. Between the years of 1870 and 1970, it is estimated that 150,000 kea were killed by hunters who were paid bounties by the local government. Keas were hunted because their actions indirectly killed sheep. They would bite the backs of sheep and eat the fat stored near the kidneys. The sheep would often die later of an infection. The kea did this because, in the harsh winter months, the food that they would normally eat it is hard to find. One hundred years after the hunting began, a wildlife census found that there were only 5,000 birds left in the wild. After this, keas were granted partial protection until 1986 when they were given full protection under the Wildlife Act of 1953. Now, there are estimated to be 1,000-5,000 keas in the wild, making them a nationally endangered species. The Cincinnati Zoo & Botanical Garden has teamed up with the Kea Conservation Trust (KCT) with the hope that they can successfully increase kea populations. They use population research using vhf video tracking, nest monitoring devices and kea repellents to reduce human-wildlife conflict. The Zoo also sponsors KCT staff attendance at Human Wildlife Conflict Collaboration which enables the KCT personnel to enhance their skills of first response human-wildlife emergencies. In addition, the Cincinnati Zoo has the largest collection of keas in North America and is committed to their conservation. At the time of my lab rotation, the keepers had successfully bred a pair and their chicks were a few months old. After learning about kea and interacting with them, I wanted to find out what I could do to help them. I learned that there are numerous ways that we can help spread awareness and conserve their natural habitat. It can be something as simple as telling someone about kea, donating money to the Kea Conservation Trust, or placing change in the interactive enrichment puzzle at their exhibit. Every small contribution adds up to make a huge impact. Next time you come to the Zoo make sure that you make a stop by the flight cage and visit the kea. They really love interacting with new people!
