This coming Wednesday, July 29, is International Tiger Day, and the Cat Canyon keepers and volunteers are gearing up for our 2nd annual celebration. We will also be celebrating the birthday of our Malayan tigers, Taj and Who-Dey. They will turn eight years old on July 30.
Like last year, keepers and volunteers will be on hand at the Malayan tiger exhibit to talk with guests about tigers and how we can help save this critically endangered species of which scientists estimate there are less than 350 individuals remaining in the wild. (The total estimate of all tiger subspecies combined is less than 3,200 remaining in the wild.)
Why are Malayan tigers in such big trouble? The most immediate threat today is from poaching and the illegal wildlife trade in tiger body parts used in traditional Asian medicine. The loss of forests on which tigers rely, which are rapidly being converted to palm oil plantations, is another major threat. Add to that the competition with hunters for sambar deer and other natural prey, which can lead tigers to attack livestock and increase conflict with people.
Since 2006, Panthera, a leading conservation organization focused on wild cats, has led the charge to stabilize and restore wild cat populations across the globe, including tigers. Panthera’s approach is to put as many boots on the ground as possible to protect tigers as well as promote co-existence between tigers and people.
The Zoo has pledged support to Panthera’s Tigers Forever program, which trains local rangers to patrol forests, gather intelligence and arrest poachers. In 2014, Tigers Forever added three new sites for a total of 15 sites under protection. This represents 36% of the world’s critical tiger sites. Panthera’s goal is to expand Tigers Forever to 50% of these sites by 2016.
New camera technology is also being deployed to prevent poaching. Panthera’s Technology team has developed the V5W PoacherCam, a hidden camera that uses an imaging algorithm to distinguish people from wildlife. When a person is detected, the PoacherCam instantly transmits the image to law enforcement who can immediately respond to the threat. PoacherCams will be distributed to Tigers Forever sites beginning in 2016.
Meanwhile, here at the Zoo, our Malayan tiger brothers, Taj and Who-Dey, continue to impress guests and help us spread awareness of the need for tiger conservation. We invite you to come celebrate International Tiger Day with us on July 29. In addition to talking with our keepers and volunteers and seeing Taj and Who-Dey, you can compare your hands to tiger paw prints, see example of tiger enrichment items (e.g. toys), and participate in the tigers’ birthday fun. Roar!

When it comes to incorporating natural talents into your career, few keepers have mastered the art as well as Lindsay Garrett. Not only is she super creative, but her artistic talents have come into play on more than one occasion in her role as zoo keeper. Whether she is shaping concrete for turtle enclosures or casting animal molds to raise money for conservation, Lindsay constantly finds ways to incorporate her strengths into her work.
When alligator “Lucy” was not shifting well into her holding area, Lindsay took it upon herself to trouble-shoot and come up with a solution. She reached out to keepers at other zoos for help and even built a gator-friendly ramp that would allow Lucy to feel the water in her holding pool, making shifting more comfortable for the visually-impaired crocodilian.
Additionally, Lindsay’s incredible patience and focus help make her a talented trainer. She developed a target-training program to facilitate shifting Lucy (who now shifts on cue successfully on a weekly basis!), and her colleagues call her a master of manatee training.
When it comes to educating the public, Lindsey is always willing. She even helped to develop an underwater keeper chat to help guests feel more connected to the Zoo’s manatees. Not only is Lindsay a wealth of knowledge regarding the animals in her collection, but she also conveys their environmental importance during her interactions with the public. She has also helped raise funds for conservation through her involvement with the Zoo’s American Association of Zoo Keepers chapter.
Lindsay’s positive influence even extends beyond her own department through her active involvement in the enrichment committee. Lindsay’s knowledge and insight help ensure that all the animals at our Zoo have safe and appropriate enrichment.
Co-worker Megan O’Keefe says of Lindsay: “She is ridiculously hard-working. I’ve never met anyone more on top of things than she is!” Chris Edelen said of Lindsay: “She goes above and beyond, and I am a better conservationist for seeing things through her eyes…”
Thank you for your dedication to our field Lindsay!

Plant conservation work at the Cincinnati Zoo & Botanical Garden’s Center for Conservation and Research of Endangered Wildlife (CREW) was featured in The Public Garden, the journal of the American Public Gardens Association, earlier this year in an article entitled “The Race for Plant Survival” written by Janet Marinelli. The article discussed the important role that public gardens like the Cincinnati Zoo & Botanical Garden (CZBG) play in plant conservation, the technological advancements that are being made in this challenging work, and the goals for plant conservation in the future.
The article begins with the story of the 24-year (and counting!) conservation quest to bring the autumn buttercup, Ranunculus aestivalis, back from the brink of extinction, and how such large-scale conservation efforts have become increasingly collaborative.
Shortly after The Nature Conservancy purchased land in 1991 to protect the habitat of the autumn buttercup along Utah’s Sevier River, they realized that just setting aside protected land wouldn’t be enough. The population was dwindling too fast, and additional partners would be needed to save this federally listed species. Seeds were collected from the mere 20 remaining plants at the preserve and sent to CREW. Valerie Pence, CREW’s Director of Plant Research, germinated the seeds to grow a handful of genetically unique individuals. She then used her expertise in micro-propagation to develop tissue culture protocols for the autumn buttercup and the power of tissue culture to make hundreds of “copies” of these plants in vitro in test tubes.
The tiny plants were sent to Arizona to enter the care of the next partner in the process, the Arboretum at Flagstaff, which potted the plants in soil and prepared them for out-planting in their native habitat. The out-plantings and subsequent monitoring of the plants was achieved through additional partnerships with the U.S. Fish & Wildlife Service and Weber State University.
Three out-plantings since 2007 demonstrate how this reintroduction effort has required the long-term commitment and collaboration of several stakeholders to continue to boost the autumn buttercup population until it is self-sustaining. The autumn buttercup story is a great example of “integrated conservation”, whereby public gardens partner with government agencies, non-profit organizations, and universities to preserve endangered plant species. Learn more here.
Multifaceted conservation strategies are increasingly incorporating technology into species survival plans, which often combines reintroduction of plants into their native habitat, banking seeds and tissues in long-term storage, and maintaining living collections in gardens and arboreta. For example, the Frozen Garden in CREW’s CryoBioBank uses liquid nitrogen and cryogenic technology to store seeds and shoot tips of some of the most threatened plant species, like the autumn buttercup, at very cold temperatures.
However, even if species are banked, their native habitat may be changing faster than the plants can adapt to the changes. Advancements in molecular genetics ensure that public gardens are also preserving the genetic diversity of the species that are banked and in living collections. Therefore, when plants are ready for reintroduction, higher genetic diversity should increase their chances of survival in the wild and ability to adapt to changing conditions. Plants that are especially vulnerable to changes in climate include certain long-lived, slow growing tree species.
Globally, more than a thousand tree species are considered critically endangered. One aspect of their biology that makes them a conservation challenge is that many species of trees produce seeds that are not easily frozen in seed banks. Oaks, for example, produce large acorns that don’t survive freezing. CREW scientists helped develop techniques to dissect the tiny oak embryos out of the acorns, which they were then able to cryopreserve.
CREW scientists tested the technique using four endangered oaks and three were successful! More research is needed, but these advancements at CREW will improve conservation strategies for endangered oaks and other large-seeded tree species.
Unifying the plant conservation effort is the Center for Plant Conservation, which is made up of 39 gardens, including CZBG. This network of gardens safeguards seeds, tissues, and specimens of 788 of the rarest native plant species in the United States. With nearly 5,000 species considered at risk, there is much work ahead to achieve the goals of the Global Strategy for Plant Conservation, which includes preserving 75% of plant species in living collections and seed banks by 2020.
While achieving these goals may seem daunting, what is known is that the future of plant conservation will continue to be collaborative, it will rely on technological advancements like those developed at CREW, and public gardens like CZBG will continue to be at the forefront of this critical conservation effort.
