There are currently 16,306 plants and animals listed as endangered by the International Union for Conservation of Nature (IUCN). That’s more people than visit our Zoo on a typical spring day.
It’s Endangered Species Day, so you might hear a lot of shocking numbers like this, which could understandably put a damper on your day. If you wanted to make a difference, which of the 16,000+ would you even choose to start with? Well, you don’t have to choose. All plant and animal life is interconnected, which means that by taking small actions that support a healthy ecosystem, you can benefit all species, including our own!
If you’re visiting our blog, you’re probably passionate about animals and the environment. That passion gives you power. Let’s look at how you can harness your power to make Endangered Species Day the start of significant change.
What does “endangered” actually mean?
It’s a good idea to first understand what we mean by the term. In the 1990s, the IUCN developed the Red List of Threatened Species™, widely recognized as the standard for evaluating a plant or animal’s risk of extinction. They rank species along a continuum from “least concern,” to “vulnerable,” followed by “endangered,” the more serious “critically endangered,” and finally, “extinct.” Watch this video to learn more.
The U.S. Fish and Wildlife Service also maintains a list of endangered species, as do state and local agencies. Around our Zoo and others, you might see signs that display an animal’s IUCN classification. For example, you’ll see that the red pandas are considered “vulnerable,” while the black rhinos are “critically endangered.”
As we’ve said, one positive environmental action holds the potential to affect a lot of different areas. We’re all living on the same planet, so shopping with reusable bags here in Cincinnati really does have ripple effects for polar bears in the Arctic!
Here at the Zoo, you can bring us your old cell phone for recycling, which reduces the need for mining metals in endangered gorilla habitat to make new ones. Go a step further by collecting phones at your school or around your neighborhood.
You can also support our many conservation field efforts. Cheetahs, western lowland gorillas, and keas are just a few of the species we’re actively involved with conserving in the wild. When we work to protect these animals’ habitats, we also benefit countless other species with whom they share space.
You don’t need to limit your choices to those you can carry out at the Zoo. Change can begin in your own backyard…literally. Plant native plant species in your yard. They’ll attract native insects which, in turn, will attract other native species that eat them, and native species that eat them. More pollinating insects means more native plants and, you see, the cycle really gets going!
As a team, organizations accredited by the Association of Zoos and Aquariums (AZA), like ours, have made strides in restoring more than 30 species to healthy wild populations, including the American bison, the California condor and a variety of aquatic species. (Read more about AZA efforts here.)
There has been good news just over the past year. In 2015, the IUCN moved the Iberian lynx from “critically endangered” to the less severe “endangered.” The Guadalupe fur seal went from “threatened” down to “least concern.” The global community has taken new interest in restricting trophy hunting thanks, in part, to the publicity surrounding Cecil the lion’s tragic death. Change can happen.
And just last week, we received good news for a critically endangered species that is near and dear to our hearts, the Sumatran rhino. A female rhino calf was born on May 12 at the Sumatran Rhino Sanctuary (SRS) in Indonesia. The calf’s father, Andalas, was born here at the Zoo in 2001 and moved to the SRS in 2007. With fewer than 100 Sumatran rhinos left on the planet, this birth is significant for the species, and we are proud to have played a part in it.
There are infinite choices you can make to promote positive change, but you’ll be most successful if you start with one or two that really speak to you. You’ll help ensure that currently endangered animals are still around for your children and grandchildren to enjoy and, more importantly, you’ll improve life on Earth for all of us.
And be sure to tell your friends and family. The power of your passion is contagious!

For more than 20 years, Dr. Bill Swanson (CREW’s Director of Animal Research) has been working in Brazil to conserve Latin American felids (animals in the cat family). I was fortunate to get to travel with him to Associação Mata Ciliar (AMC), a non-profit organization that promotes the conservation of over 300 plant and animal species. AMC’s Centro Brasileiro para a Conservação Dos Felinos Neotropicalis (Brazilian Neo-Tropical Feline Conservation Center) is the largest feline conservation center in the country, which houses eight of the ten cats endemic to Latin America. Habitat loss and poaching have threatened most of these species with extinction in all or part of their natural ranges. Specifically, we’ve come to AMC to work with jaguars and tigrinas, which you can read about in my previous blog post!
Two experiences from the last few days on the road in Brazil stand out. One, collecting semen from a puma, was planned and part of the reason for our visit. The other was an unexpected encounter with a boa constrictor.
A Cat by Any Other Name…..
The puma has many aliases: cougar, mountain lion, panther, and catamount to name a few. Why so many? The puma has a vast range across the Americas, from high in the mountains to lowland deserts. Thus, this extremely adaptable cat has encountered many different cultures which call it many different names (even in Portuguese, at least two names exist: onça-parda and suçuarana).
Faced with fragmented habitats and dwindling wildlife prey, puma populations are currently on the decline in Brazil. Here, pumas are considered near threatened, with certain subspecies classified as vulnerable. During our visit, we helped AMC start a semen bank for pumas. First, the male is anesthetized so we can collect semen.
Next, the sample is processed with a specialized medium that contains cryoprotectants and loaded into “straws”. Finally, the straws are frozen and stored in a liquid nitrogen tank for future use.
Historically, if a male dies before he has a chance to breed, his genetic contributions are lost forever. This semen bank represents an important safeguard against that loss, preserving the puma’s genetic diversity within a liquid nitrogen tank. The semen bank can facilitate gene exchange between pumas at different locations without the need for animal transport. Because semen can be stored in liquid nitrogen for decades, centuries, or perhaps even forever; semen banks can expand gene exchange across time, allowing a puma to contribute to the gene pool indefinitely.
Why did the snake cross the road?
Local authorities often contact AMC to assist with distressed wildlife. In this case, the county police rescued a boa constrictor that was located dangerously close to a highway. Once at AMC, veterinarians draw blood to screen for ectoparasites and other diseases.
The snake was then transported to Serra do Japi, a 350 square kilometer (135 square mile) nature reserve of the Mata Atlântica (Atlantic Forest), located in a mountain range just outside the city of Jundiaí. Five hundred years ago, the Atlantic Forest spanned across 330 million acres of Brazil. Today, it’s estimated that less than 15% of this once vast forest remains. Despite being only a fraction of the size of its more famous neighbor the Amazon rainforest, the Atlantic Forest remains lush with endemic species and rivals the biodiversity of the Amazon.
Japi was classified as a Reserve of the Atlantic Forest Biosphere in 1994. To help preserve wildlife, access to Japi is extremely limited and the general public is not allowed inside. Indeed, we were only granted access to release the snake. Once inside, I was astounded by the beauty of Serra do Japi. Such a stark contrast to the crowded city of Jundiaí, Japi is a beautiful reminder of what this area used to look like: trees thrust upwards creating a lush green canopy above, and a series of rivers and waterfalls carving out the rocks below.
After driving down a windy road for about 15 minutes, we decided on our release location. Despite my fear of snakes, Cristina (veterinarian and Wildlife Coordinator at AMC) was kind enough to let me help with the release. Also helping were AMC trainees Gabriel (a veterinary student) and Natahlia (a biology student) who clearly did not share my snake phobia. Gabriel carried the transport box to the side of the road and we slid the lid open. Gabriel coaxed the snake out with a hook and off he (or perhaps she) went!
There is something truly beautiful about releasing an animal back into the wild, particularly in a case like this when not only did we prevent an almost inevitable occurrence of a vehicle strike, but we also relocated this snake to a beautiful (and protected!) area far away from the urban sprawl of Jundiaí.

Back in the early 1990s, an eager young post-doctoral fellow was hired to study cat reproduction at the Smithsonian’s National Zoological Park. One of his first projects involved a small-sized, little-known Central Asian felid called the Pallas’ cat (Otocolobus manul).
At the time, there was a grand total of one male Pallas’ cat in all U.S. zoos – a wild-born Mongolian cat named Gek. The post-doc dutifully collected and evaluated Gek’s semen every two months for almost two years and, for the first time, documented the extreme reproductive seasonality typical of this species. Concurrently, he froze Gek’s semen for long-term storage.
Fast forward 22 years later. That post-doc, Dr. Bill Swanson, is now CREW’s Director of Animal Research, and in early 2015, found himself in desperate need of frozen Pallas’ cat semen. Fortuitously, he previously had acquired Gek’s samples from the National Zoo. Frozen semen from Gek and two other males was used for laparoscopic oviductal artificial insemination (LO-AI) of four Pallas’ cats at three U.S. zoos (Cincinnati, Columbus, Pueblo). Two of those cats appeared to conceive; however, only the Columbus Zoo female subsequently gave birth. Her single kitten was fully developed, but, unfortunately, stillborn.
Notably, the father of that kitten was … (drum roll, please) …Gek! The pregnancies and birth were the first ever with frozen semen in Pallas’ cats but also established a new longevity record for frozen semen fertility in any wildlife species. Additional LO-AIs using Gek’s frozen samples are planned for 2016 – hopefully followed by the birth of healthy kittens this time around. Long-live Gek!
