Big Trees of Los Alamos County 2013

Measuring a big Douglas Fir.

This is a sad list to compile. Beginning in 2005 an intrepid group of interested people located big trees in Los Alamos County, excluding Los Alamos National Laboratory lands. They found the biggest evergreens in Cañon de Valle and at Cañada Bonita. The Las Conchas Fire in 2011 killed most of those trees and many of the second and third runners up. This list seems a pale shadow of our previous champions, but they are our trees to love.

Due to the elevation of the county, several species, while present and true trees at lower elevations, become little more than shrubs here. Thus we eliminated several from the big tree search. Gambel oak grows as a tree in Los Alamos Canyon but the Lab closed the area to the public. (There are nice specimens in Frijoles Canyon just downstream of the Falls Trailhead in Sandoval County.) We had a little grove of hawthorn trees at Upper Crossing in Frijoles Canyon; the Los Conchas Fire incinerated them. We should have corkbark fir but no one has reported one yet. The Fremont Cottonwoods at Ashley Pond and in White Rock are planted, but there may be some natives along the Rio Grande. I left in hackberry trees, although ours are pretty wimpy; also boxelder, even though we could not find a specimen with only one trunk.

We use methodology developed by the non-profit group American Forests to compare trees. This group maintains the National Registry of Big Trees. The State Forestry Division of the Energy, Minerals and Natural Resources Department maintains New Mexico’s Big Tree Program. We provide data from these two lists in the description of each tree species. The American Forests Big Tree formula is as follows:

Total Points=circumference(in.)+height(ft)+[average canopy(ft)/4]

For each tree we give circumference in inches (C), height in feet (H), and average canopy crown in feet (Cr). It is difficult to find many of these trees without a GPS, so I list the UTMs, NAD 83.

As always, if you find a bigger tree, PLEASE let us know!
