New Mexico, East to West Vegetation Megatransect in cross-sections, compiled from pictures from the Confluence.org project.

New Mexico ecological and vegetation photo megatransect in cross-sections, running east to west along each degree of north latitude.

Compiled by Craig Dremann, (650) 325-7333, for scientific study of what a large-scale, continent-sized ecological and vegetation photo megatransect could possibly look like, photos copyright by the photographers that are listed on the pages at confluence.com. Photos on this web page are used here with written permission from the Confluence Project.

Green dots show the locations for each photo of this megatransect.
Nearby towns are noted for each picture.
Some photos have been cropped or have had their contrast enhanced,
to show the vegetation more clearly.


New Mexico rainfall



DREMANN GRASSLAND SCALE (DGS). Utilizing the photos below, I am suggesting rating the quality of the native grass understory using the following scale:

Scale goes from minus 10 to 0 to positive 10.

0 equals less than 5% native grass cover, and every point in the minus zone equals no native grasses and 10% exotic plant cover.

In the positive, every point equals 10% native grass cover, up to 80% native grass cover or 8 points. Then the 9 and 10 equals the forbs in the interspaces, until you reach 10, which is 100% native grass and forb cover.


Annual = annual average maximum total number of inches of rainfall for that site, according to the above map.
