Today was our first day of field work. We worked with Dr. Hong Liu and two graduate students from Beijing Forestry University to set up a pilot climate chamber in Yachang Preserve. The day began with a trip to Leye to find PVC pipe. We wondered if it would be available in such a small and remote city, but were happy to discover an abundance of PVC retailers. We waited in the car while our driver negotiated a “local” price. We assembled a miniature greenhouse in an area of high orchid diversity known as the orchid garden. We are testing the greenhouse to see if we can replicate climate change conditions. Even a temperature increase of <1.0 degrees can have a great impact on plant reproduction, fungal symbionts, soil moisture, and countless other factors. When we finished constructing the chamber, we installed one temperature logging unit inside and one outside. Tomorrow and for the next several days we will download the data to examine the difference. If we are successful, Hong will use this method to study orchid response to climate change.

Miami plants in Yachang
Fri, May 28, 2010 at 10:14:27 PM
By Jennifer Possley
Over the past few days, Hillary and I have been enjoying our hikes through Yachang Orchid Preserve. Ecologically, the preserve has much in common with Miami's natural areas. Both are at similar latitudes, and both are considered to be subtropical. In addition, both have a karst limestone substrate-- though the substrate in Yachang is definitely more dramatic! But because of these similarities, Miami and Yachang share many of the same plant genera and species. Scroll down to see some of them for yourself!
This passionvine looks very similar to Miami's own endangered Passiflora sexflora.
Hillary took this gorgeous shot of a shrub in the Melastomataceae family. In Miami, we have a single native species in the Melastomataceae: Tetrazygia bicolor (West Indian lilac).
The grass in the foreground here is Imperata cylindrica or "cogon grass," one of the world's worst weeds. Cogon grass is actually native to China. Here it is blooming-- something it rarely does in Florida.
Miami has three common species of Smilax vine (S. auriculata, S. bona-nox, and S. havanensis). This Chinese member of the genus has much larger leaves than any of the Miami species.
This beetle is sitting atop a non-native shrub that is actually one of Miami's native pine rockland plants: Chromolaena odorata. In Miami pine rocklands it can proliferate in disturbed areas. Here in the Guangxi province, it is a ubiquitous roadside weed.
Here is another one of Florida's weeds: Lygodium sp. I'm not sure what species of climbing fern is in this photo, but Lygodium microphyllum and L. japonicum are both major problems in Florida's natural areas.

| Karst hills surround Leye. |
After a couple of days in transit we've arrived in Leye, just outside of Yachang Orchid Preserve. We are staying here for a few days as we accompany Richard Stone of Science Magazine on a tour through the preserve. He is interested in writing an article about Yachang and is spending a few days exploring and learning about the orchids here, as well as the people and projects in place to protect them. As tag alongs, Jen and I are getting a fantastic orientation to our research location and the issues at hand. Dr. Liu's long range goals include gathering information that will be of value to preserve managers who grapple with threats such as encroachment from farmers, poaching, and climate change. Hong and other scientists are working with managers to strategize approaches that will meet the needs of the local community while providing for long term conservation of orchid species. I'm excited to contribute to these efforts in the coming days.
This past winter and spring Guangxi province experienced what could be the worst drought in a century. It may have had significant impacts on orchids and surrounding vegetation. To prevent damage, preserve managers installed irrigation in remote areas to provide supplemental water to orchid habitat. Unfortunately if this drought is a sign of new climate trends, then watering could be detrimental to conservation objectives. Long-term survival of species requires that they are able to adapt to changes in their environment.

Corn is a valuable crop for local farmers. Even on preserve land, they continue to clear trees and expand their plantings farther and farther into orchid habitat. |

Behind the Scenes at Beijing Botanical Garden
Sat, May 22, 2010 at 10:18:39 PM
By Jennifer Possley, Field Biologist
Today was our whirlwind tour of botanic gardens in Beijing. Dr. Yi-Bo Luo of the Institute of Botany, Chinese Academy of Sciences kindly dedicated his entire Saturday to showing Hong, Hillary and myself around the 400-hectare Beijing Botanical Garden. To begin our tour, we met Dr. Luo at his office at the Chinese Academy of Science. He was our free pass for the day; when we walked across the street to the botanical garden, his presence enabled us to sail past the long lines like VIP guests. We first met with Dr. Shiwei Zhao, the Garden’s Vice Director. Hong presented him with 
materials about the Fairchild Challenge, and invited Dr. Zhao and the Beijing Botanical Garden to become one of our growing number of partner institutions. He expressed interest in learning more about the annual training program that Fairchild runs for its international partners. After this meeting, we spent several more hours in the garden. We toured the elaborate indoor rainforest exhibit, and we visited the Buddhist “Wofosi” or the Sleeping Buddha temple that resides on the garden property and houses a large reclining Buddha statue. My favorite part of our tour was the behind-the-scenes look inside the orchid nurseries. We saw row after row of perfect and beautiful orchids of all sizes, colors and scents, including the rare species from Yachang Orchid Preserve, Paphilopedilum hirsutissimum (upper left photo) and Dendrobium officinale (lower right photo). Dendrobium officinale has been poached, nearly to extinction, because it is prized as a treatment for diabetes.
By the way. . . Hillary and I were surprised to see an old friend at the Beijing Botanical Garden: Bigfoot is alive and well in the rainforest exhibit!

Arrival in Beijing
Fri, May 21, 2010 at 08:46:22 PM
By Hillary Burgess, Fairchild Living Collection Manager
Dr. Hong Liu, her son Eugene, Jennifer Possley, and I arrived in Beijing yesterday evening. We are staying for a couple of days near Beijing University to facilitate meeting some of Hong’s research collaborators prior to our departure to Guangxi and the Yachang Orchid Preserve. Today we ate lunch with Dr. Chen Zhang-Liang, the Vice Governor of Guangxi, Richard Stone, Asia – Pacific editor for Science Magazine, Senior Vice Dean of the College of Life Science at the Peking University Dr. Hong-Ya Gu, and the leading orchid Biologist Yi-Bo Luo of Beijing University.

We were hosted at a restaurant on the site of a royal garden from the Qing Dynasty. Jen and I had a chance to learn more about the research that is being done on orchids within Yachang by professors Liu, Gu and Luo and their students. There are several exciting ongoing investigations on orchid population dynamics, pollination, mycorrhizal fungi associations, and the effects of climate change. Many rare orchids are highly specialized, making them especially vulnerable to changes in their environment; understanding each of these factors is critical for conservation efforts. Climate sensitivity is of particular interest for this trip, as Jenn and I will be helping Hong establish a pilot study within Yachang to investigate the potential impacts of climate change on rare orchid populations.

Eagle Scout project removes unwanted invasive plants
Wed, May 05, 2010 at 02:42:26 PM
By Evan Hacker (Boy Scout Troop #457)
On Saturday, April 17th, 2010 my Eagle Scout project took place at Fairchild Tropical Botanic Garden and the University of Miami’s Smathers Four Fillies Farm Preserve from 9 a.m. until about 2 p.m. Over 70 volunteers contributed 295 hours of their time to help remove non-native invasive species such as Oyster plant (Tradescantia spathacea) and Jacquinia (Bonellia macrocarpa). At one of the removal sites, “the island”, we used handsaws and shovels to remove the unwanted plants. At the other 3 sites, volunteers hand pulled the invasive species. We planted approximately sixty-four native plants and chose one plant to commemorate Troop 457’s hard work with an identification plaque.
Everyone had an enjoyable afternoon, especially because there was a huge feast for lunch. Some scouts even said “it was the best lunch at any Eagle Scout project ever”. We were able to use the picnic table constructed at the site before it was moved to its permanent location at Four Fillies. Fairchild was very happy with the outcome of our environmental work during the week of Earth Day. The day was an absolute success!
I would particularly like to thank Fairchild Tropical Botanic Garden and the University of Miami for allowing me to have the opportunity to complete my Eagle Scout project on their properties. Sam Wright, Hillary Burgess, Eric Fleites and Bob Brennan all contributed their time, energy and expertise to help set up my project and carry it out smoothly.
Thank you, Pirates Patrol, for coming and supporting me the day of my project. Both Scouts and parents acted as team leaders and assistants; they all provided needed extra hands to carry out the project. Thank you, also, Mr. Burg, Eagle Scout Project king of setting-up! Also, a big thank you to the Ziskas who were a huge influence in guiding me from the very beginning of my service project idea to the take down of the site on the afternoon of the activity.
