While we are delighted that the panda was downlisted poignant and personal moments that have marked this journey. from Endangered to Vulnerable last year on the IUCN Red List of Threatened Species, we know this beloved animal still needs our help—the goal is nothing less than a sustainable population on remembers his beginning as if it were yesterday.

After weeks of rain, snow, and sleet, the sun came out and Maggie Aleksic at 760-747-8702, option 2, ext. 5762, or email [email protected]. the “Wolong guys” got out a basketball. Ron decided to join the daily game and almost immediately everything changed. Poor cooperation turned into good friendships, and two decades of camaraderie and collaboration followed. ON THE COVER: Bai Yun has been a phenomenal mother to all six of her cubs. Here she is dandling her fifth cub, male Yun Zi, born in 2009. Continued next page 2 . Continued from page 2 A FEW YEARS LATER, MEGAN ARRIVED AT WOLONG “signs”: feeding sites, scent marks, and especially on a cold winter evening with her family in tow—husband, their droppings, which provide a treasure trove toddler, and baby—ready to embark on four months of research of information. These include diet, DNA, in the heart of the giant panda’s home. Children are beloved gender, and hormones. And, since they leave there, so Megan and her family were quickly integrated into about 50 of these nuggets a day, they leave the social fabric of Wolong. Being part of this extended family a perfect record of where they’ve been not only made the tea warmer and the food tastier, it also and their habitat preferences. meant that the Wolong staff was keen to work with Megan We now understand that female toward our collective research goals.

Panda habitat is increasing as forests recover, tracking devices on pandas the panda’s range is expanding, and panda numbers in the wild are up: they scientific approaches to so we could monitor their are on the road to recovery. We celebrate this accomplishment, a testimony conservation of giant pandas movements as well as to how hard work and persistent collaborative efforts can rescue endangered and their habitat. learn from studying their species from the brink of extinction.
