What happens to conservation when the water runs dry???

Thoughts by Ashley Terry

Western Pound Turtle

The Western Pond turtle (or WPT as we refer to them around the zoo) is the only freshwater aquatic turtle native to California. Traditional habitats range from Baja California to British Columbia, but in recent years that habitat has begun to shrink due to habitat destruction and the introduction of non-native species into their environment. They are now extinct in British Columbia, critically endangered in Washington and endangered in Oregon. Here in California, they are considered a species of special concern.

The larger of the two turtles was head started, the smaller not. Both are the same age.

Each nesting season, Oakland Zoo and Sonoma State students and biologist spend a month tracking, marking and monitoring gravid female WPT’s and viable nests at our field site in Lake County. This is the sixth consecutive year that zookeepers have spent in Lake County, and to date, we have successfully Each nesting season, Oakland Zoo and Sonoma State students and biologist spend a month tracking, marking and monitoring gravid female WPT’s and viable nests at our field site in Lake County. This is the sixth consecutive year that zookeepers have spent in Lake County, and to date, we have successfullyraised and released close to 450 turtles- each season yielding around 45 hatchlings or more – through our head start program. Check out this cool video of the WPT at the Zoo. The goal of the Head Start program is to raise the hatchlings for the first year under optimal conditions. By creating the best possible environment for the turtles, they grow 3-4 times faster than they would in the wild.  At the end of the first year, the juvenile turtles are then released back into Lake County, having grown too large to be eaten by common predators like big mouth bass and eastern bull frogs.

WPT’s live in typically riparian habitats where they can most often be found in sloughs, streams, and large rivers, although some may inhabit bodies of water such as irrigation ditches and other artificial lakes and ponds, too. Turtles are generally active from late May to October. WPT’s overwinter, or hibernate, in both aquatic and terrestrial habitats. Terrestrial overwintering habitats consist of burrows in leaf litter or soil. In more wooded habitats along coastal streams in central California, most pond turtles leave the drying creeks in late summer and return after winter floods.

California has experienced continuous dry conditions since 2012; alternatively known asdrought.  According to the National Drought Mitigation Center at the University of Nebraska, Lincoln, 99% of California is currently abnormally dry; 67% of California is in extreme drought, and almost 10% is experiencing exceptional drought.  The repercussions of our drought emergency are relatively simple: there is an extreme lack of water.  The absence of water impacts Californians in several different ways, whether it is economically or socially.  But how does it affect the state’s wildlife or our conservation projects here at the zoo?

Those involved with our Head Start program have noticed that the last few drought years in the field have been incredibly stressful on the Lake County turtles in several distinctive ways. In some less permanent waters, such as our field site, the fact that the ponds have dried up completely for the first time in many years has certainly affected the behavioral patterns of WPT in some key ways, thus affecting the numbers of gravid turtles and viable nests sights during our field seasons. Since the ponds dried up by July and August of the last 2 years, the turtles were forced to estivate – spending a hot and dry season in an inactive or dormant state – when they would normally have been feeding and stocking up their internal reserves of protein and fat. The extended time they spent in this state of “suspended animation” also leaves them much more vulnerable to any manner of disturbance – especially in the case of predators, temperature extremes, etc. Lastly, and maybe most important for our head start program, the non-permanent lakes & ponds were dry when the turtles should have been feeding and mating. This was reflected in the very low numbers of nesting females last summer, giving us only 4 hatchlings this season.

 

Although these impacts of drought do indeed bring about urgent circumstances for wildlife, it is important to remember that droughts are, unfortunately, natural phenomena. Climate scientists predict that California will get even hotter and drier. As more of the state’s precipitation falls as rain instead of snow in the mountains, it will run off the land more quickly, ending up in the ocean. Scientists say that with global warming, we’ll see more instability in California’s climate, with more intense storms, longer dry periods, and less snowpack. It will be interesting in the upcoming future to see how long it takes to get back to the normal population numbers at our site, and to track the behavioral changes due to impact of habitat change. In the meantime, we are also looking at other possible locations where population numbers can be monitored. Wildlife and drought have coexisted for generations upon generations. For the most part, wildlife populations are able to bounce back from drought events once typical weather patterns return. For the time being, we’ll keep our fingers crossed for a very wet and rainy winter, resulting in turtles returning to our pond.

Oakland Zoo and you taking action for wildlife!

by | October 10th, 2014

Humans long to connect to nature. We are hardwired to be a part of the whole of our habitat, to breathe in fresh air, to sit under the shade of a tree, to awake to birds, to gaze at a sunset, to wonder at stars. In our busy urban lives of cars and offices and computers, we forget this deeply ingrained part of us. When we do get out in nature, we take deep breathes, reboot, relax and reconnect with our simple humanity.

I think we are finally realizing how important this connection is. It is no wonder concepts such Nature Deficit Disorder, Nature Therapy, and Eco-Psychology have emerged. It is no wonder doctors are prescribing time in nature as medicine, those with illnesses are healed with the friendship of therapy horses and dogs, and schools are slowly adopting environmental education into their curriculums. This awakening gives me great hope.

However, modern media brings to us daily sad truths about the condition of our planet. Concepts like the sixth extinction, global warming, habitat fragmentation and fracking have become part of our general knowledge. The ivory crisis, the illegal wildlife trade, the invasive species epidemic and more are making headlines. This bombardment of bad news can give any of us a case of Eco-phobia, or a feeling of helplessness about our future. Some question whether caring or taking action will make a difference.

Yet, it is clear people care. On September 21st when 400,000 people marched through the streets of New York and thousands marched world-wide demanding attention be paid to global warming, it became clear that the citizens of the world care indeed, and that most people who care are ready to transform that feeling into action.

If I may quote Dr. Jane Goodall, “Every individual matters. Every individual has a role to play. Every individual makes a difference.” We agree.

Oakland Zoo celebrates these notions in us all by launching our new conservation concept, “Action for Wildlife“. Through Action for Wildlife, we have a clear platform to illuminate the incredible species we share our planet with, communicate their conservation challenges and introduce our partner organizations that are conserving them. We also celebrate the zoo’s own accomplishments using our spectrum of resources to fully support these efforts. Most of all, Action for Wildlife acknowledges you, our community. We aim to engage our visitors, members, students and greater family in joining us to take action for wildlife, and we hope to help inspire actions that make a bigger difference than you can imagine. We believe that our family of 750,000 can make a huge difference in the lives of wild animals.

Just by coming to the zoo, you have taken action for wildlife through Quarters for Conservation, where 25 cents of your entrance fee and a dollar of your membership cost goes to wildlife conservation. Our three new projects, Big Life, Centre ValBio and Ventana Wildlife Society are great examples of outstanding action for wildlife, and each of us can truly help. Big Life supports elephants in Kenya. You can take action for elephants by refusing to purchIMG_1841ase ivory, choosing to avoid circuses that use elephants and supporting elephant conservation organizations. You can be inspired the Centre ValBio in Madagascar and conserve lemurs by avoiding the purchase of rosewood. You can help the California condor, like Ventana Wildlife Society, by refraining from hunting with lead bullets and picking up trash.

 So join us, your zoo, as we embark on a journey that will bring us closer to who we are meant to be as humans. Let’s appreciate wildlife, connect to wildlife and take action for wildlife together.

Please join us on Action for Wildlife Day on Saturday, October 18th at Oakland Zoo. There will be fun, learning, interactive stations, face-painting, a selfie station inspiration for ways that YOU can take action for wildlife. In celebration of this day, two rare experiences will be offered: A tour of  our state-of-the-art Veterinary Center and a real Baboon Experience!

 

 

 

Oakland Zoo Welcomes New Educator

Recently, Oakland Zoo welcomed a new member to its Education Staff. Katie Desmond is the new Creek and Garden Programs Manager. Raised in Sebastopol (Sonoma County) Katie earned her BS in Biology and Animal Physiology at Sonoma State University. Later she worked at nature preserves where she led workshops for kids. In 2010 she arrived here at Oakland Zoo, where she worked as an intern, helping with the Western Pond Turtle Project. Following a three-year stint at Safari West near Santa Rosa, Katie returned to the Zoo as a full time employee in the Education Department.
As part of her new position here, Katie oversees the restoration and upkeep of the Zoo’s Arroyo Viejo Creek which runs through Knowland Park on its way from the Oakland hills to the bay. She will also be helping to establish a series of themed gardens in the Education Center courtyard. Seven in all, these will include a native California wild edibles garden; a waterscape with marshy habitat for aquatic plants; a xeriscaped drought-resistant sun garden; and several others with different types of soil, utilizing urban composting. The Zoo’s horticultural staff will help with the big job of designing and planting. Katie will eventually be developing a curriculum to go with each of these gardens, so they can serve as “living laboratories.” At a later time when the gardens are established, school kids will become involved, learning about the different types of plant communities when they visit the Zoo.
As the coordinator of the creek program, Katie will also be facilitating the intrepid Creek Crew, an ever-changing group of various outside volunteers that meet here every 3rd Saturday of the month. She’ll be helping them with their ongoing goal to restore the creek to its former natural, healthy state.
In her spare time, Katie enjoys reading, gardening, hiking and snowboarding. Asked why she’s here at Oakland Zoo, Katie says she wants to help educate people about the environment we live in. So let’s all welcome Katie to her new position here, and we look forward to her enthusiastic involvement with Arroyo Viejo Creek!

 

A Creek Runs Through It

by | August 12th, 2014

The natural occurrence of clean water used to be commonplace throughout the world. But these days, especially within urban settings, water needs all the help it can get. Part of that help involves taking care of the waterways that wind their way through our neighborhoods. Here at Oakland Zoo, our group of dedicated teen volunteers, the Teen Wild Guides (or TWGs), have been doing just that, helping the local creek return to its natural, healthy state. Along with a wide array of other volunteers, the TWGs have been joining the ongoing effort to restore habitat along Oakland’s Arroyo Viejo Creek, which runs through Knowland Park on its way to San Leandro Bay. These volunteers, who range in age from 10 to 100 years old, include high school groups, families, church groups, scout groups as well as alumni and corporate groups.photo (22)

During several weekends last year, the TWGs assisted the Zoo’s Education Department and Horticulture staff in leading Arroyo Viejo Creek volunteers and various community groups with the following projects: planting native species including Stipa grass plugs; clearing dirt debris and invasive plants from an adjacent new lawn area; clearing weeds from around new oak saplings and mulching around nearby trees; and creating a wooden border between a new parking area and the habitat restoration site to prevent native grasses from being damaged by zoo guests.

photo (14)Funding for the tools and materials needed for this restoration work has been provided by a generous $4900 grant from the Alameda County Flood Control and Water Conservation District’s Clean Water Program and Community Stewardship Grant Program. But the TWGs’ contributions to the creek’s welfare have gone beyond performing physical labor. These teens understand how important clean water is to the environment and humans, and that riparian habitats are critical for wildlife and ecosystem functions.

With this in mind, they’ve also assisted with sharing conservation information with our volunteers on a variety of pertinent topics, including:DSC02973

  • What are Watersheds?
  • Why watersheds are so important
  • Invasive Plant Species
  • Native Plant Species
  • Edible plants that are found alongside the creek
  • Riparian habitats
  • Animals that inhabit riparian habitats at the creek

Through their involvement with the county’s Clean Water Program, the TWGs have learned how to restore native vegetation on creek banks and wetland transition zones, and how this work has contributed to the long-term protection and biological health of streams, aquifers, and terrestrial resources of our watersheds in the North Bay. As part of this grant, the TWGs have also worked with teen volunteers at Fruitvale’s Peralta Hacienda Park, restoring native gardens and working on the restoration of Peralta Creek. The Oakland Zoo TWGs are always looking for new members. If you know an enthusiastic teen who’s interested in animals and community service, give the Zoo a call at 510-632-9525 ext 201. It could be the opportunity they’ve been waiting for—the chance to help make a difference in the natural world!

Big News For Big Birds

by | June 2nd, 2014

Condors are certainly big news at Oakland Zoo right now with the recent arrival of the first two birds at the newly-opened Steve and Jackie Kane Condor Recovery Center. As you may know, condors are the highly endangered cousins of the vultures that you see in the skies all over California. And like vultures, condors play a vital role in the ecosystem by feeding on the carcasses of dead animals. When these animals are shot by hunters or ranchers, the lead pellets in turn are ingested by the condors. It takes only a tiny fragment of lead to make a condor very ill. These lead-poisoned birds need medical care in order to survive, which is where the zoo comes in. For the past three years we’ve been working with the Ventana Wildlife Society near Big Sur, California, an organization that has been leading conservation efforts to save the California condor for decades. When a sick bird is spotted in the mountains around Big Sur, it’s carefully captured by Ventana’s condor vets and conservationists and brought to our facility. Once here, it’s treated by specially-trained Oakland Zoo veterinarians who provide treatment for the condor until it is healthy enough to be released back into the wild. And you’ll be happy to know that one of the aforementioned birds has already gotten a clean bill of health and has been returned to her home!
But there’s more to our condor program than medical procedures. In April, a small group of young zoo volunteers had the opportunity of attending a special camp about condors. Held at the research facility within the Ventana Wilderness Area, Condor Camp is a 4-day program that lets people observe and participate in the conservation work being done by the Ventana Wildlife Society. This was the first time kids from the zoo (both Teen Wild Guides and Teen Assistants) had the chance to participate in this exciting program. Over the four days they went on a night walk, spotted condors that were feeding on dead seals and sea lions at the Pacific Ocean, and visited the feeding slope and re-release cages used by the staff. They also got to check out the Condor Cam, the remotely-controlled video camera that allows visual monitoring of the birds from the research center. But most exciting, the kids got to use the radio antennas and other equipment to locate the condors, some of whom regularly migrate between Ventana and their other stronghold at Pinnacles National Monument.

And then there’s Condor Class. An educational program for middle and high school students, this half-day class held at Oakland Zoo is an on-site version of the new interactive Field Biology Workshops. The 20-30 students (from science classes at a variety of local schools) get the chance to use the high-tech tools of biologists, such as telemetry equipment and GPS units to track the birds, which all have ID tags and their own individual radio frequencies. The students practice with this equipment by finding hidden stuffed animals, study condor data gathered in the field by biologists and make scientific recommendations for the birds’ welfare based on that data.
So as you can see, there’s a lot of condor activity going on at Oakland Zoo these days. Although the birds here aren’t available for public viewing, you can be sure they’re receiving the medical care they need to get them back out in the wild as soon as possible, thus helping to ensure their continued success in returning from the brink of extinction!

Celebrate Earth Day with a Party for the Planet!

by | March 25th, 2014

Imagine you and your family and friends on a beautiful spring day dancing to live music, building with pine cones, learning to juggle,  meeting your next feline or canine family member and having a ball all while helping the planet? This is how Oakland Zoo celebrates Earth Day!Earthday 2007_123

Humans around the globe have been celebrating their connection to and reverence of the planet for centuries. It makes sense that our modern society would create a day such as Earth Day: a special day set aside to appreciate and take action for our one precious planet. Earth Day was first officially celebrated in the United States in 1970, and is now celebrated in nearly 200 countries each year.

Oakland Zoo also feels that the Earth is indeed something to celebrate, and therefore we produce one of the largest Earth Day events in the East Bay.  This year our event is on Saturday, April 19th and we are calling it a Party of the Planet.

DSCN1077

Earth Day fits our mission perfectly: To inspire respect for and stewardship of the natural world while creating a quality visitor experience. What could be more inspiring than making a genuine connection with over fifty visiting organizations who work to help animals and the environment?  Other inspiring experiences will include creating with natural objects in the Create with Nature Zone and making beaded necklaces that help the lives of people and chimpanzees. Quality experiences will be had by all, such as a full day of educational shows in the Clorox Wildlife Theater with live animals, the Jug Bandits Band and Wildlife Action Trivia. Quality fun will be bountiful the meadow with our giant earth ball, circus antics, face painting and a real trapeze show with Trapeze Arts.

Other highlights of Earth Day include: a free train ride with donation of used cell phone or ink cartridge, voting for your favorite conservation project at the Quarters for Conservation voting station, Oakland Zoo docent and eduction stations, and of course, visiting our resident animals.

To further walk the talk, Oakland Zoo will be hosting our monthly Creek Crew clean up of Arroyo Viejo Creek on the grounds from 10:00 AM – 1:00 PM.DSCN1072
