This forest type is part of the semi-deciduous microphyll forest.
Because it grows in such difficult environmental conditions (shallow soil, high rockiness, stoniness, gravelness, high temperatures, high evaporation and marine salt spray influence), this forest is much stressed, which is expressed in its microphyll, sclerophyllous and semi-deciduous character (Reyes & Acosta, 2004).
As a whole Chameophytes were dominant and their percentage were 26.38 followed by microphylls, nanophylls and mesophyll.
It was followed by microphylls and nanophylls having the contribution of 18.37, and 16.33% respectively (Table 2).
The leaf size spectra revealed that nanophylls were dominant with 26 (72.22%) species followed by microphylls with 4 (11.11%) and mesophylls with 3 (8.33%) species (Fig.
Relative importance values of plants associated with antelope jackrabbit sign and observations in the Central Gulf Coast subdivision of Sonoran Desertscrub (xeric microphyll shrub) were: brittlebush Encelia farinosa (55.3%), creosote L.
This microphyll semi-deciduous forest was altered by intense selective logging, which has changed its structure, yet maintains its floristic composition.
A microphyll semi-deciduous forest with many sclerophyllous species locally presents in stressful environmental conditions, caused by a poor soil development and / or a marked water deficit, often with accentuated wind affection (BORHIDI, 1996).
