My Florida Torrey 2020 Status

I am a Torreya Guardian, one of a dozen or so people who work to prevent the extinction of one of the most endangered conifers in the world. The Florida torrey, Torreya taxifolia, has an extremely restricted range that is located at the triple point where Florida, Georgia, and Alabama meet. Although it has protected habitat in Florida, especially within Torreya State Park and nearby conservancy preserves, it is there infested by a fungus (Fusarium torreyae) that kills nearly all torreys before they are mature enough to set seed. Connie Barlow reasoned that the best way to save the species was to assist in its migration to cooler climes where the fungus may not be able to survive. She and others collect seed annually for distribution to the rest of us. Hence, my plantings in the Blue Ridge Mountains of western North Carolina. So far, I have put 18 seedlings in the ground on my 2+ acres, 14 of which have survived to this day. The other four were killed by voles chewing through taproots blocking their way when digging their tunnels. This blog post documents the status of the remaining 14 as of today. The single torrey that was planted within the mature mixed forest here has grown the least, and now, nine years later, has grown to a height of only 13 inches:
The largest two were planted alongside my driveway where they get 4-5 hours of direct sunlight a day. Now, eight years later, they are 71 inches tall:
The others are intermediate in size according to the amount of insolation that they receive. Here's a couple of them:

  2. Eight years and only 71 inches tall!!!???? A bit discouraging for us immediate gratification twenty-first century folks eh?

    1. Yeah, but they get only 2-3 hrs a day of direct and another 2+ hrs of indirect sunlight per day. And FWIW a few of them have grown a foot or more in each of the past two years. The sky's their limit!!!

  3. It is good someone is trying to save this species! Good work!
