History of Torreya Guardians• Endangered Species Action
• Climate Activism
• Citizen Science
Torreya Guardians is a self-organized group of naturalists, botanists, ecologists, and others with a deep concern for biodiversity protection, who have chosen to use the internet as a tool for discussing ideas, posting plans, and taking a variety of actions in behalf of our most endangered conifer tree: Torreya taxifolia.
There are no by-laws, officers, board, staff, overhead costs, dues, formal organizational structure, or physical location to this organization.
Torreya Guardians does not speak or take action as a group, but instead encourages subsets of those involved to post ideas and initiatives on this website and to help establish links with synergistic organizations and websites.

"The well-known case of the Torreya Guardians that have translocated seedlings of Torreya taxifolia
to more northerly latitudes in North America represents an independent citizen action
of very involved and proactive people."
Roxane Sansilvestre et al., 2015
Reconstructing a deconstructed concept: Policy tools for implementing assisted migration for species and ecosystem management
Environmental Science & Policy
Just before the 2015 global climate conference in Paris, The Economist included an 8-part "special report" on climate change. The biodiversity section features the work of Torreya Guardians as the USA example of climate adaptation underway. Online access: "A Modern Ark: To save endangered species move them to more congenial places".
EXCERPT: Along the banks of the Apalachicola river, near the border between Florida and Georgia, lives a rare tree called a stinking cedar. Once common, Torreya taxifolia seems to have got stuck in this tiny pocket as the continent warmed after the last ice age. It cannot migrate northward because the surrounding soils are too poor. Attacked by fungi, just a few hundred stinking cedars remain along the river. Rising temperatures now threaten to kill them off entirely.
Spying a looming extinction, a group of people is engaged in a kind of ecological vigilantism. The self-styled "Torreya Guardians" collect thousands of seeds a year and plant them in likely places across the eastern United States. Stinking cedar turns out to thrive in North Carolina. The Torreya Guardians are now trying to plant it in colder states like Ohio and Michigan as well. By the time the trees are fully grown, they reason, temperatures might be ideal there.
Some are dubious. The Torreya Guardians were at first seen as "eco-terrorists spreading an invasive species", remembers Connie Barlow, the group's chief propagandist. She rejects that charge, pointing out that she is only moving the tree within America. She also thinks that drastic action of this kind will soon be widespread: "We are the radical edge of what is going to become a mainstream action."
In 2015, Kara Rogers published a book (left) that includes a detailed chapter on Florida Torreya (University of Arizona Press). The end of that chapter highlights the work of TORREYA GUARDIANS. Access sample excerpts here.
The Quiet Extinction: Stories of North America's Rare and Threatened Plants is also accessible via google books.
VIDEO: Site Visits to Florida's Endangered Torreya and Yew Trees
Connie Barlow presents 15 years of baseline photos and videos she recorded of Torreya taxifolia and Taxus floridana in their historically native range in Torreya State Park in northern Florida. Photos of spectacular California Torreya trees, recorded by Barlow in 2005, show the potential for Florida Torreya recovery efforts to strive for. Fred Bess shows (in 2014 video) 2 Asian conifers (Cephalotaxus and Cunninghamia) used in landscaping that are Torreya look-alikes. Paleoecological evidence that Florida's Torreya was "left behind" in its peak glacial refuge supports "assisted migration" actions. (Note: This is episode 17 in an ongoing VIDEO series of Torreya Guardians actions.)
Editor's note 2015: Following this brief section, the rest of this webpage is unaltered in order to preserve the original roster of volunteers and advisors. Many additional volunteers have since stepped forward to help propagate and plant Torreya taxifolia. Consult the state-by-state pages accessed from our homepage to learn where and by whom propagation is occurring.
Although this "assisted migration" advocacy was initiated by Connie Barlow, who drew from a paleoecological perspective to surmise that Torreya taxifolia was suffering from climate change in its historically native range (and therefore deserved to be assisted northward to more suitable habitats), not all volunteers are participating for the same reason. Connie was moved to act precisely because the official management plan for this endangered species, even as updated in 2010, did not authorize participating scientists to begin assisted migration experiments. Access in pdf Connie's 2010 comments to USF&WS.
A 2013 paper confirmed what Torreya Guardians has known from the outset: that our actions are legal, despite our operating beyond the scope of the official management plan. The Endangered Species Act contains an apparently intended loophole for plants. See "Commercial Trade of Federally Listed Threatened and Endangered Plants in the United States", by Patrick D. Shirey et al.
Another aspect of our diversity: While evidence indicates that the mountains of North Carolina offer suitable habitat today, not everyone in the group would support the efforts by some of us in even more northern states, where we are planting Torreya seeds and seedlings in order to ascertain whether the species can survive even colder climates and in anticipation of continuing warming this century.

Editor's Note: An inability to reach consensus (among the above list of communicators) on the next step for Torreya taxifolia action, led Connie Barlow and Paul S. Martin to draft an advocacy piece for the final issue of Wild Earth magazine, and for Mark Schwartz to submit a rebuttal. Access both papers of the Winter 2004/2005 issue Wild Earth Forum: "Assisted Migration for an Endangered Tree". At the same time, Barlow and Martin published a set of proposed Standards for Assisted Migration on this website.
The next major step was the July 2008 "Rewilding" action at Waynesville and Lake Junaluska in North Carolina. Access photo-essays of 2008 Torreya action and Chronology of Events leading up to the 2008 action.
An archived history of the early debate over terminology is also available: "Assisted Migration or Assisted Colonization: What's in a Name?".
