Plant species composition in a rosetophyllous desert scrub of northern Coahuila, Mexico

The Maderas del Carmen Flora and Fauna Protection Area (APFF), located in the state of Coahuila, is considered a natural reservoir for rosetophyllous scrub, which has been affected by land use change in northern Mexico. The objective of this work was to describe the current state of the rosetophilou...

description	The Maderas del Carmen Flora and Fauna Protection Area (APFF), located in the state of Coahuila, is considered a natural reservoir for rosetophyllous scrub, which has been affected by land use change in northern Mexico. The objective of this work was to describe the current state of the rosetophilous desert scrub in the Maderas del Carmen Flora and Fauna Protected Area, based on its structure, floristic composition, and diversity. Vegetation was evaluated using 35 plots of 5 m x 5 m in 7 linear transects. Height (m), diameter (cm) and crown area (m2) were measured. Abundance, dominance and frequency of each species were determined to obtain the importance value index (IVI), in addition to the Shannon entropy index (H´) to know the diversity, and the true diversity of Shannon (1D). 31 families, 61 genera and 70 species of vascular plants were recorded, including one endemic to Mexico (Galactia brachystachys) and 20 under protection status, such as Agave havardiana, which is also a vulnerable species. The richest families were Fabaceae, Asteraceae, Asparagaceae and Cactaceae. Biological and life forms were trees and shrubs (48 %), herbs (36 %), succulents (13 %), and climbers (3 %). The H’ was 3.13 and the 1D was 22.87. The rosetophilous scrub of the APFF Maderas del Carmen has a medium-high diversity, it is dominated by Agave lechuguilla Torr., with greater abundance and IVI. The floristic composition and the diversity found allow a baseline for subsequent studies that determine the ecological status of the area. Especially, they allow us to know in greater detail the population dynamics of endemic species and under protection status, in addition to the habitat for wildlife present in the APFF Maderas del Carmen.

El Área de Protección de Flora y Fauna (APFF) Maderas del Carmen, ubicada en el estado de Coahuila, se considera un reservorio natural para el matorral rosetófilo, el cual ha sido afectado por el cambio de uso de suelo en el norte de México. El objetivo del presente trabajo fue describir el estado actual del matorral desértico rosetófilo del Área Protegida de Flora y Fauna Maderas del Carmen, con base en su estructura, composición florística y diversidad. Se evaluó la vegetación mediante 35 parcelas de 5 m x 5 m en 7 transectos lineales. Se midió altura (m), diámetro (cm) y área de copa (m2). Se determinó abundancia, dominancia y frecuencia de cada especie para obtener el índice de valor de importancia (IVI), además del índice de entropía de Shannon (H´) para conocer la diversidad, y la diversidad verdadera de Shannon (1D). Se registraron 31 familias, 61 géneros y 70 especies de plantas vasculares, incluyendo una endémica de México (Galactia brachystachys) y a 20 bajo estatus de protección, como Agave havardiana, que además, es especie vulnerable. Las familias con mayor riqueza fueron Fabaceae, Asteraceae, Asparagaceae y Cactaceae. Las formas biológicas y de vida fueron árboles y arbustos (48 %), hierbas (36 %), suculentas (13 %) y trepadoras (3 %). El H´ fue de 3.13 y la 1D de 22.87. El matorral rosetófilo del APFF Maderas del Carmen tiene una diversidad media-alta, está dominado por Agave lechuguilla Torr., con mayor abundancia e IVI. La composición florística y la diversidad encontrada permite una línea base para estudios posteriores que determinen el estatus ecológico de la zona. Especialmente para conocer con mayor detalle la dinámica poblacional de las especies endémicas y bajo estatus de protección, además del hábitat para la fauna silvestre presente en el APFF Maderas del Carmen.
