Who Are Torreya Guardians?   

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.

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 had known from the outset: that our actions are legal, despite our operating beyond the scope of the official management plan. The Endangered Species Act contained 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.
