Most people don't think of snails as being endangered, particularly if they are battling them as they eat through their Swiss chard patch. But Woodland Park Zoo is helping a species of Tahitian tree snail back into their rightful place. The Partula snail used to be represented by around 100 different species in the islands of French Polynesia. But thanks to (or no thanks, in this case) an invasive, and carnivorous, snail, Partula were reduced to about five species in less than 10 years in the 1980s, and only remnant survivors of those few remaining populations. Thankfully, scientists recognized what was happening and rescued about 17 species before they disappeared. Our zoo has been the U.S. hub at captive breeding efforts for one of these species, Partula nodosa, and currently has more than 900 of these half-inch long critters behind the scenes in Bug World. A rarity in the snail world, Partula give live birth to a single offspring every 4-6 weeks, as opposed to a typical brown

Posted by: Jona Jacobson, Woodland Park Zoo Conservation “Komodo lizards are…big. Very big. There’s one on Komodo at the moment which is over twelve feet long and stands about a yard high, which you can’t help but feel is entirely the wrong size for a lizard to be.” - Douglas Adams, Last Chance to See While big, most Komodo dragons don’t reach quite that size, averaging between 6.5 to 10 feet and weighing in at around 150 pounds. Komodo dragons are the vultures of the four Eastern Indonesian islands they inhabit: they eat carrion . That doesn’t mean, however, they won’t eat other things as well, including hatchling Komodo dragons, whose survival instincts have them scurrying up trees, where they stay until large enough to not be such easy snacks for the adults. WPZ has provided funding to the Komodo Survival Program since 2000. The group’s recent study examines the spatial ecology of juvenile Komodo dragons. Huh, you ask? Field researchers captured 5 hatchling an

We were greeted with sunny skies yesterday morning for this summer's western pond turtle release. Twelve endangered turtles, headstarted for a year at the zoo, were taken to a protected pond site in the Lakewood area for the next step in their life cycle : life in the wild. A full contingent of helpers, including zoo staff and volunteers, 7-year-old Aimee Kessler and project donor Maryanne Tagney Jones, received the honor of gently putting the little turtles, weighing around 2 ounces each, into the waters of their new home. State biologists Michelle Tirhi and Tammy Schmidt checked over the turtles, ensuring that they were correctly marked (small notches are made in their shells for future identification, as well as tiny numbered tags). Michelle notes that the project has had a 95% rate of success in raising turtles since 1996. But we'll let the photos speak for the day. The zoo has proudly worked on this project for nearly two decades, increasing the wild population of these

Today's the day for about 50 western pond turtles to returned to the wild. For more than a decade, the zoo has raised state endangered western pond turtles and then released them into protected pond sites in southwestern Washington state. At that time, only about 100-150 of the turtles, which measure about 8-inches long as adults and can live nearly four decades or so, were left in just a few spots in Washington (other subspecies live in Oregon and California, but are having similar problems). Why endangered? Introduced critters such as bullfrogs would gulp up the tiny hatchlings, about the size of a 50 cent piece. Also the drastic decline in wetlands and ponds to residential and agricultural development put a serious crimp in living places. Thanks to the efforts of the zoo, Frank Slavens, former reptile curator here and his wife Kate, the Washington Department of Fish and Wildlife, Oregon Zoo and many others individuals, there are now an estimated 1,400 turtles living in sites in

Last night's concert was great! Both opening act Josh Ritter and featured performer Andrew Bird were at the top of their game and the weather, despite the rather foreboding clouds that had been around all day, actually warmed up a bit. The sold out crowd seemed to appreciate their talents as well. I was working the zoo's Conservation booth, talking with people about the more than three dozen field projects the zoo supports. It was remarkable how many people already knew a lot about several of the projects, including our work with the Snow Leopard Trust and the Grizzly Bear Outreach Project , but we were able to provide some details about other projects, too, including the Western Pond Turtle Recovery Project and the Oregon Silverspot Butterfly Project . The next three concerts are sold out, but The Avett Brothers on August 27 still has tickets available at our sponsor, Metropolitan Markets . (Photo of Josh Ritter and Andrew Bird by Ryan Hawk)

It’s National Zoo Keeper Week—the perfect time to recognize the incredible work that our dedicated animal management staff does to not only keep the zoo’s animals healthy and happy, but to also teach our visitors about conservation and zoology. The job of the zookeeper is much more than feeding and cleaning up after animals. Today’s keepers engage the animals in their own care, using training and enrichment to give animals the opportunity to act like their wild selves. Keepers must keep close watch over the animals in their care in order to detect any signs of illness, which animals instinctually hide to avoid predation. Keepers also contribute to the overall body of knowledge about animals by participating in behavioral research, and many are active in international conservation efforts. If you think a career as a zookeeper may be right for you, take a look at our zoo careers webpage and our keeper FAQ to learn more about the day-to-day realities of the job and what it takes

When an elderly patas monkey was diagnosed with painful kidney stones, our zoo vets went to work to relieve her discomfort in the least invasive way possible. After consulting with urologist Dr. Joseph Marquez from Seattle's The Polyclinic, the zoo's animal health experts decided to use a procedure that, though used often on humans, is uncommon on zoo animals. The 15-year-old monkey, named Fiona, was treated with a high-tech procedure that blasts kidney stones to passable pieces by repeated exposure to sound waves. Using a lithotripsy machine, generously supplied by NextMed, to send the sound waves, the team was able to break down Fiona's kidney stones into hundreds of small pieces that could then pass through her urinary tract. Fiona is recovering well now at the zoo's award-winning African Savanna exhibit. After just one day, she was feeling much better than she had in the weeks leading up to the procedure, according to her vets. Photo of procedure by Ric Brewer.
