Efforts to Save Torreya taxifolia
by Connie Barlow, founder of Torreya Guardians
(updated May 2022)
OVERVIEW OF THE PROGRAMS: This website (Torreya Guardians) was initiated in 2005, 19 years after the U.S. Fish & Wildlife Service had established a recovery plan for Florida Torreya, which had been designated "endangered" in the USA in 1984. This page is intended to present (and link) all the official government publications, as well as online publications and news by or about the institutional and volunteer organizations working in their own ways on behalf of species recovery.1.

FLORIDA TORREYA AS CASE STUDY IN CLIMATE ADAPTATION: "Efforts to save" Florida Torreya began so early, and have met with such controversy, that this subcanopy "glacial relict" tree is now regarded as the classic case internationally for difficulties in moving forward with climate adaptation in conservation biology and restoration ecology.

IUCN Redlist Endangered Species
IUCN "Conservation Actions" extract for this Critically Endangered species:
CONSERVATION ACTIONS: Torreya taxifolia has been the focus of extensive conservation interventions. The majority of its range lies within protected areas. Regular census' are carried out to monitor the state of the remaining trees. An ex-situ programme was initiated in the 1980s and clonal collections have since been established in several areas away from its native habitat. Some reintroduction work has been attempted within its natural range but this has not been successful to date. Various research programmes have been initiated to identify the causal agent of its decline: these are ongoing. T. taxifolia was listed as federally Endangered by U.S. Fish and Wildlife Service in 1984. A recovery plan was formulated in 1986 and has recently been reviewed and updated (U.S. Fish and Wildlife Service 2010).
1. OFFICIAL PROGRAM: U.S. Fish & Wildlife Service
The prime advantage of the official recovery program is that it is authorized to work directly with Torreya specimens growing naturally within the historically native range. Professional collaborations have been established with governmental institutions in Florida and Georgia, as well as with botanical gardens and universities in those and other states. The biggest constraint has been that the recovery plan (1986, updated in 2010) has not been written or interpreted in ways that include experimentation with "assisted migration" into natural forested habitats northward of the northernmost region of Georgia. While "assisted migration" has from the outset been a controversial topic among professional conservation biologists, a formidable obstacle for U.S. national (and likely state) governmental agencies is that mention of past and ongoing anthropogenic climate change as a reason for undertaking assisted migration propels management decisions into a highly contested political arena.

USDA Forest Service scientist Tyler Dreaden and colleagues from the University of Florida are developing a genetic test to identify the torreya fungus. This work can ensure the health of the collections and reduce unknown risks to other species. The researchers drew on published DNA sequences for F. torreyae canker pathogen and genetically related species. They mined these genetic codes to find the parts unique to the torreya pathogen. The technique successfully distinguished the torreya fungus from other related fungal species. The next step and ultimate goal is to develop the method further so it can quickly detect the torreya fungus directly from Florida torreya tissue samples. This study brings hope to expanding conservation efforts that preserve the genetic variation of Florida torreya in anticipation that it can thrive once again....

Two weeks after the storm, Dr. Coffey conducted a high-level assessment and was astonished by the damage. Heartbroken, she stood at the top of a ravine and found 80-90% of the mature trees gone. But there was also a glimmer of hope. With the crowns of trees strewn everywhere, she scrambled down a steep ravine in search of one of the largest trees documented in the park – and found it alive. This tall, beautiful female torreya had produced one of the first recorded seedlings in more than 20 years. And the seedling was also still standing! A huge grapevine had prevented a large sycamore from falling directly on the female torreya. It was a very precarious situation, requiring hours of careful planning and saw work to prevent the sycamore from crushing the torreya. “In the end, we were able to save the tree and leave renewed and filled with hope that we would be able to save more trees, and that not all of the individuals had been lost,” Dr. Coffey recalls. "It gave us great resolve and hope, which is what we continue to thrive on." ... Some Florida torreya supporters are keen to help the species by relocating the trees or seedlings into the Appalachian Mountains. The garden is working hard to avoid the spread of the fusarium into the Appalachian wilderness.• CPC page for Atlanta Botanical Garden (lists contact emails)

(1967) and Stalter and Dial (1984), but the Florida Torreya Recovery Plan (USFWS 1986) noted that applications of Maneb, Benomyl, Daconil (Chlorthanlonil) and Zyban to Torreya trees in Maclay Gardens over the past 25 years have not succeeded in controlling the blight (USFWS 1986). Fungicide use at Torreya State Park has also been unsuccessful (Martin 1987, pers. comm.).

Note: When Connie Barlow accessed this page in 2022, "assisted migration" was presented as a "threat" to this species: "Logging, conversion of habitat to pine plantations, fungal blight, extreme hurricane events, diversion of resources to uninformed and unauthorized assisted migration efforts." In the section titled "Conservation Management Recommendations" this appears: "Discourage attempts at assisted migration unless carried out by authorized agencies."

A large-scale ex situ effort began in 1985, funded by the CPC and the Arnold Arboretum (Nicholson 1996). Rob Nicholson and Mark Schwartz collected cuttings from 163 wild lineages of T. taxifolia and then distributed resulting plants to 10 institutions in North America and Europe in the early 1990s. Using a 1996 Arboretum inventory of 156 of the original lineages as a foundation, we conducted an international inventory of this species in 2009 and tracked down all possible specimens that originated from the original CPC material. Fortunately most of the lineages had been preserved among the institutions surveyed (a bene t of backing up collections). But about 20% were represented by only one or a few remaining plants per lineage, and about 40% of lineages existed only at one or two institutions. Lessons learned from this long-term ex situ effort include ensuring a collection holder has appropriate horticultural know-how, climatic compatibility, and staff commitment for successfully maintaining a collection. For example, a loss of 70% of unique lineages at the Arnold Arboretum was observed from 1989 to 2009. This loss is attributed to incompatible climate, poor adaptability to container nursery conditions, and human error (staff changeover, labeling errors, etc.). Further, 5 of the 8 institutions still maintaining the original T. taxifolia germplasm required accession data cleanup and several specimen identifications were determined lost or unknown due to accidental dissociation with accession numbers, labels, or records.... As a result of the 2009 ex situ inventory for T. taxifolia, redistribution of germplasm has occurred among collection holders to preserve and back up ex situ maternal lines at multiple institutions. Further, this inventory led to a successful transfer of this important CPC collection from the Arnold Arboretum to the Atlanta Botanical Garden in 2010."• Florida torreya entry (p. 440) in Field Guide to the Rare Plants of Georgia (by Linda Chafin, 2007)TG Editor's note August 2020, by Connie Barlow: It appears that this transfer of original rooted branchlets from Arnold Arboretum ultimately ended up at the Gainesville GA campus of Atlanta Botanical Garden, northeast of the main campus, and that these rooted branchlets have had to survive in containers for 3 decades. Unless care was taken to 'bonsai-prune' roots and branches to maintain health while confined in a small container, it is a testament to the species' persistence that these specimens have survived at all. Thus, in the 2020 book by Zach St. George, The Journeys of Trees, the author observed the torreya specimens at the Gainesville site and concluded (p. 83), "The torreyas of Gainesville were pitiful indeed. They were crowded together, bent and twisted under the shade canopy, sick from the same fungus that afflicted the wild trees." This editor (Connie Barlow) doubts that the apparent "sickness" was from the fungal Fusarium torreyae, as it is becoming increasingly apparent that, while the fungus is being documented on virtually all T. taxifolia specimens that are tested, it seems to produce lethal cankers and leaf dieback only when environmentally triggered (such as in its native Florida range). Jennifer Ceska of the State Botanical Garden of Georgia (Athens GA) suggested this interpretation of the Gainesville Torreya collection in her detailed audio interview of November 2019 in the "In Defense of Plants" podcast series. Access the interview with Ceska (along with Connie Barlow's summary, transcript excerpts, and analysis of key points and possible misinterpretations by Ceska). Also, access the Medford OR torreya page to see the size that rooted branchlets will become when not confined to constricting containers (the Medford torreys are only about a decade older than the "sickly" specimens now at the Gainesville site).

NOTE ON OFFICIAL EX SITU PLANTINGS - Initially, ex situ plantings focused on same-latitude sites, notably:• Maclay Gardens / State Park/ Tallahassee, FL - The 1986 Recovery Plan notes trees at this location. It appears these trees had the blight or contracted it shortly after planting. Trees are still growing onsite. Original trees were planted at this site in the 1930s and they were being treated for disease since 1955.In the 21st century, official outplantings have shifted to northern Georgia: Smithgall Woods, Vogel State Park, and a location in Blairsville. More detail on the Smithgall Woods State Park Torreya Seed Orchard in northern Georgia can be found in the "Comments" column of this USF&WS matrix of recovery actions: Record of Actions. See excerpts below:
• Harrison Experimental Forest / US Forest Service / Saucier, MS - Three trees from a population there were used in a photosynthetic experiment. Torreya Guardian Paul Camire queried by email in 2018 and learned that several specimens have died and the 15 remaining trees (sickly, 5ft and under in size) are struggling and infected with the blight. Editor's note: This location is only about 20 miles inland of the Gulf Coast, so rampant disease is not unexpected.Georgia: The ABG and the Georgia Department of Natural Resources outplanted 19 individuals of T. taxifolia at the Smithgall Woods in White County in north Georgia. The purpose of the Smithgall Woods collection and two additional off-site plantings (Blairesville, GA and Vogel State Park) were to establish safeguarding populations of Torreya to conserve material that had been propagated at the ABG in backup collections at more than one location. The material planted at Smithgall Woods was propagated from all Georgia source population material (Army Corps. Of Engineers, site at Woodruff Dam, Lake Seminole, in Georgia). The trees have grown quite large and are now reproductively mature producing male and female cones annually. Most of the plants were placed in full sun and they are quite healthy. The trees at Vogel State park are smaller than those at Smithgall Woods and have not yet reached reproductive maturity.The 2010 Recovery Plan Update (p. 9) documented seed production at Smithgall Woods:The Atlanta Botanical Garden (ABG) and the Georgia Department of Natural Resources outplanted 19 individuals of T. taxifolia at the Smithgall Woods in White County in north Georgia.

The material planted at Smithgall Woods was propagated from all Georgia source population material (Army Corps. of Engineers, site at Woodruff Dam, Lake Seminole, in Georgia). The trees have grown quite large and are now reproductively mature producing male and female cones annually. Most of the plants were placed in full sun and they are quite healthy. Major threats to the trees at this location are lawn management (weed wackers) and fire ants. The trees at Vogel State park are smaller than those at Smithgall Woods and have not yet reached reproductive maturity (Cruse-Sanders 2010, pers. comm.).Atlanta Botanical Garden January 2019 update, published online, "Recovery of the Florida Torreya - one of the rarest conifers in the world," Ecological Restoration Alliance of Botanic Gardens (one page)
Editor's note - Seed production on the Atlanta campus of the Atlanta Botanical Garden began before 2007, as this 2007 article by ABG staff stated, "... Many of the original Arnold Arboretum cuttings have matured into cone and seed producing trees [at Atlanta Botanical Garden] that, in total, form over 500 viable seeds per year on average. These plants are grown in the ABG "seed orchard" and propagules produced from these seeds have been used to facilitate the next phase in the recovery of this species." Torreya Guardian founder Connie Barlow posted photographs of the AGB seed production and germination operation during her second site visit to AGB December 2007.EXCERPT: ... In 1990, Atlanta Botanical Garden received 155 clones of T. taxifolia propagated from the remaining natural population by Arnold Arboretum and the Center for Plant Conservation. This material has been safeguarded at the Atlanta Botanical Garden since that time, and propagation efforts have increased the collection to include almost 1,000 plants, including nearly 500 distinct vegetative clones from the wild. One of the limiting factors to ex situ conservation of this species is the inability to use conventional seed storage techniques for preserving germplasm. Torreya taxifolia produces recalcitrant wet seeds that cannot be dried for storage in freezers. Therefore, until recently the only way to maintain ex situ germplasm was through living collections. In collaboration with Georgia Institute of Technology, a somatic embryogenesis tissue culture system was developed to initiate cultures, produce somatic seedlings and cryogenically store cultures of T. taxifolia. PHOTO CAPTION: Torreya taxifiolia seed orchard (a collaborative project between ABG & UGA) - This female tree was grown from lateral cuttings and, along with 20 others, was planted in 2000. Nearly 5,000 fruit were harvested in 2016.Atlanta Botanical Garden June 2019 Update, published online, "Atlanta Botanical Garden opens Southeastern Center for Conservation this summer".EXCERPTS PERTAINING TO FLORIDA TORREYA: ... This summer the garden opens its Southeastern Center for Conservation, a $7 million two-story building adjacent to the Fuqua Orchid Center. It was funded through the successful $53 million Nourish and Flourish fundraising campaign, which included $40 million for capital improvements and $13 million for the endowment. The new center will serve as a home for the garden's conservation, education, and experimentation. The building includes a 3,800-square-foot research facility with a molecular lab that lets scientists examine genetic material at the nucleotide level. The cold-storage seed bank is augmented by cryogenic coolers that can preserve the embryos of the Torreya trees as they try to determine why the trees die in the wild before they can become adults.UF/IFAS Extension Leon County, article by guest columnist Stan Rosenthal (U Florida Forestry Agent Emeritus) published in Tallahassee Democrat, 11 November 2022, titled "Here's how to create a vegetative privacy fence that blooms, feeds wildlife."
... They also feel the pain when a natural disaster spoils plans. The garden had transplanted 700 Torreya trees to Torreya State Park in Florida, with noted Harvard biologist E.O. Wilson, 88, as a guest of honor. Then, Hurricane Michael destroyed the entire stand, dumping hardwoods on top of little saplings. "It can be really discouraging," said Carter. But even if they're not successful now, they retain hope for future prospects, she said. "One thing we're doing is keeping individual genetic material alive," said Carter. "In the future, we hope there is something to be learned from holding on to these plants."EXCERPT: "... For variety you may wish to add a few eastern red cedar, Florida torreya, Florida yew, southern magnolia, American holly, cherry laurel, and for wet areas, Florida anise. The cherry laurel will do a great job but will spread quite readily. All the aforementioned plants are evergreen."
Editor's note: The article links to a U Florida website that entails distinct pages on a vast variety of trees and shrubs (from all over the world) and appears to have been created in 1994. It is "Tree selection for urban and suburban landscapes". Links from there eventually lead to a linked list of Fact Sheets for 680 Tree Species, which offer practical guidance for soil types, sunlight, etc. for tree species from all over the globe. Thus, in addition to the Fact Sheet for Florida Torreya, one also can access a fact sheet for the Japanese species, Torreya nucifera>.
Editor's Note: Two law review articles posit that the existing Endangered Species Act and regulations would allow officials to move ahead with "assisted migration" with no need for modification. They are:• "Biodiversity on the Brink: The Role of 'Assisted Migration' in Managing Endangered Species Threatened with Rising Seas", by Jaclyn Lopez, Harvard Environmental Law Review, 2015.
• "Endangered Species Act to the Rescue? Climate Change Mitigation and Adaptation Under the ESA", by Olivia Bensinger, NYU Environmental Law Journal 2017.
4. INDEPENDENT CITIZEN PROGRAM: Torreya Guardians
This program was initiated by Connie Barlow and Paul S. Martin in 2004 after informal consultations confirmed that neither governmental staff nor various experts were willing to join them in publicly advocating for initiation of "assisted migration" experiments for Florida Torreya. Their advocacy was in the form of a co-authored proposal published in Wild Earth journal: "Bring Torreya taxifolia North Now".
Action was initiated by Lee Barnes in legally acquiring seeds and then distributing those seeds to various botanical gardens and landowner volunteers. Biltmore Gardens (near Asheville, NC) became the first seed donor for assisted migration experiments. Its grove of Florida Torreya had been planted in 1939 and usually produced seeds every other year. Biltmore donations to Torreya Guardians began in 2005, with 110 seeds, followed by 200 in 2007 and 300 in 2009. (Details are available at History of Torreya Guardians).
Jack Johnston, beginning in 2007, contributed crucial skills in legal seed sourcing, propagation advice, and acquiring the potted seedlings deployed in the 2008 "rewilding" of Florida Torreya into wild, regrowth forest sites on private lands near Waynesville, NC.
ADVANTAGES OF CITIZEN INITIATIVES: Because the Endangered Species Act expressly made an exceptionfor seed and branchlet harvesting from endangered plants already established in botanical or landscape plantings prior to listing (and from any later generations of specimens outside of the native habitat locales), our citizen group of Torreya Guardians is not required to conform to actions approved in the official Recovery Plan. Overall, we have pretty much the same freedom and flexibility that nurseries and landscapers enjoy in their choices of what and where to plant. As well, those of us who are motivated to plant species for adaptation and anticipation of rapid anthropogenic climate change are not held back by political hesitancy toward accepting climate change as real. Crucially, too, because no research funds are invested in our plantings and we have no career push to publish quickly, we have the opportunity to risk "failure to thrive" thus enabling us to test northward limits and a broad range of habitat types (in our quest to delineate the very best). As Connie Barlow mentions in a 2015 video report: "Researchers want to learn before they act, while activists want to act in order to learn."
COMPILATION OF CITIZEN PROJECTS, REPORTS, AND LEARNINGS: In addition to sampling links directly on the Torreya Guardians homepage, summaries and links of actions, ongoing learnings, and results are listed chronologically at these two key pages: Learnings and Reports by Volunteers.
CONSTRAINTS: We have no official recognition, are ineligible for research or management funding, and have limited or no access to the full genetic diversity of seeds and branch cuttings that the official program benefits from. Visit this webpage: History of Torreya Guardians.

5. FLORIDA NATIVE PLANT SOCIETY SUBGROUP: Torreya Keepers
TorreyaKeepers is a project of the Florida Native Plant Society and was started by local landowners and concerned citizens working to save the Florida Torreya (Torreya taxifolia), which has become one of the rarest and most imperiled trees in the world. We work closely with recovery plan partner organizations such as the U.S. Fish and Wildlife Service, Atlanta Botanical Garden, University of Florida, Torreya State Park and others. Our primary focus is on working with private landowners to document trees, assist Atlanta Botanical Garden in preserving genetic lines, and assist landowners with management.• Extracts from the FNPS Executive Committee Meeting Minutes of 25 September 2018:
The purpose of TorreyaKeepers is to assist in recovery of the Florida Torreya tree in its native range by conducting citizen science and outreach to private landowners in support of the federal recovery plan and to provide local support to efforts for recovery partners. Our hope is that one day blight-resistant Torreya trees can be re-introduced into the native habitat, restoring the uniqueness of the Apalachicola bluffs and ravines and the tree's namesake park, Torreya State Park.Torreya Keepers Project• Article on Torreya Keepers by Leigh Brooks in 2019 issue of Palmetto, quarterly journal of the Native Plant Society (4 pages).
a. This is a request for funding from Leigh Brooks for the TorreyaKeepers project. This project is intended to last for two years, possibly longer depending on outstanding needs. Leigh provided the proposed budget for the 2 years. Funding will cover capital expenditures, salaries, workshops, materials, etc. The Executive Director has had numerous conversations with Leigh as well as Magnolia Chapter members who are participating in the project and Magnolia Chapter board members who voted to approve funds for the project as a "kick start" and to help defray costs that Leigh has been covering herself.
b. The most important discussion topics were: 1) FNPS cannot fund the proposal as written because we do not have the funds (130K) nor can we support new staff positions, vehicles and equipment. 2) We seek clarification of what actually is being asked of FNPS – i.e. to fund the budget as proposed? To serve as the nonprofit home for future fundraising from other sources?
After discussion it was decided that FNPS should request that the project remain within FNPS and not have the project to go somewhere else or into a new nonprofit organization. However, how to stay involved without being able to fund becomes the issue. Some things to consider are:i. Keeping and funding TorreyaKeepers as an FNPS project - FNPS would help raise funds and promote it as one of our conservation projects.More discussion with Leigh and Magnolia Chapter is required and recommended. This item will remain on the FNPS BOD agenda and the Executive Committee is recommending that we meet with Leigh Brooks and the Magnolia Chapter before asking the Board of Directors to vote yes or no.
ii. FNPS (via Leigh and other volunteers) would seek grants or contracts to support this work. An obvious source is the USFWS (as this is a Federally Endangered species). If funds are secured, the project would be a FNPS program, run as any other FNPS program, subject to overhead and support expenses.
• Extracts from Work Plan for TorreyaKeepers Project, 14 September 2018 (8 pages pdf downloaded from the FNPS forum):TorreyaKeepers formed as an outgrowth of the Florida Torreya Tree of Life conference in March 2018 to aid in the recovery of Torreya taxifolia, a critically endangered species. Dr. Jason Smith (University of Florida), conference organizer and researcher of Torreya’s fungal pathogen, noted that trees appear to be perishing more quickly at present. With no known cure or treatment, time is of the essence to locate remaining trees. Since the March impetus, TorreyaKeepers has been undergoing program development. The group has begun mapping locations and collecting basic data on wild trees to support federal recovery plan tasks and the work of recovery partners. Citizen scientist volunteers have been conducting one survey each week covering approximately 20 acres. At this pace, the group will cover 1,000 acres each year.
TorreyaKeepers conducted an in-depth GIS analysis, with grant support from the Magnolia Chapter FNPS, to identify potential properties harboring Torreyas within the native range. Criteria: parcels within the watershed of the east side of the upper Apalachicola River with slope of 20 degrees or greater and 1 acre in size or larger. Parcels were consolidated by owner into properties.
Results: 987 properties covering 29,052 acres. Current volunteer resources of the TorreyaKeepers are not adequate to the challenge in the little time remaining for the trees. Recovery partners have been consulted on the best strategies for property selection to meet data and tissue collection goals. Of utmost importance will be having a dedicated, funded position to continue TorreyaKeepers work and expand its reach.
This proposal is for FNPS to serve as TorreyaKeepers’ fiscal sponsor to allow for a compatible non-profit platform for raising funds and making program disbursements.
Goals: The overarching goal of the TorreyaKeepers program is to address recovery plan tasks associated with private lands.
• Torreya Keepers (Leigh Brooks) is quoted in the 3 October 2019 issue of Tampa Bay Times: "What Hurricane Michael did to the torreya tree".
• Torreya Keepers is featured in a long-form literary essay centered on the vegetative splendor, uniqueness, and "Garden of Eden" legend of the habitat where Torreya took refuge during the cold of the Ice Age: "This Is Paradise", by Martha Park, in The Bitter Southerner, April 2021.
• APRIL 2021 UPDATE: USF&WS maintains a vast tabular page of species-specific Report Results. This information now appears on Torreya Keepers actions:2019-2020. The Torreya Keepers received funding in 2019 and 2020 from Section 6 and FEMA, respectively, to 1) seek out property owners within the predicted range of the species; 2) survey for Florida torreya trees once landowner permission has been obtained; 3) collect genetic material for analysis and propagation; 4) set up and monitor seed trials on private lands; 5) utilize and advise on best management practices, and 6) work with conservation partners to monitor trees and provide educational opportunities for students and volunteers. The TK intend to use some areas on their private lands as experimental plots to study different environmental perimeters on growth and survival. They have fenced several trees to prevent deer rubbing and damage from falling limbs and trunks of other tree species. Mr. Bill Boothe (FL private landowner) has a property with Torreya and has identified GPS locations for over 100 trees. His observations included other nearby properties comprised of about 40-50 trees of 6-15 feet tall. He would like to use private lands as experimental plots ¿ opening up the canopy, using smoke for pest control to limit die off. In general, Ms Anderson and Mr. Boothe are going to try to fence the trees to prevent against deer rubbing, and will continue to record measurements for the trees. They are willing to form the Torreya Conservation Commission at Crooked Creek, FL (see section IV, action 6).• SUMMER 2021 UPDATE: FLORIDA NATIVE PLANT SOCIETY published 2 VIDEOS about Torreya Keepers on youtube:• VIDEO: "What is TorreyaKeepers?"
