larrea: Creosote bush counts
Description
Phillips and MacMahon (1981) conducted an extensive study of Larrea tridentata (creosote bush) distributions in the Mojave
and Sonoran deserts from several life stage classes based areal coverage: Life stage 1 (102 -103 $$cm^2$$) Life stage 2 (103 -104 $$cm^2$$), and Life stage 3
(104 -105 $$cm^2$$). Data were generated to approximate the results of the authors.References
