... Vegetación Para la descripción de la flora de los sitios representativos del área de estudio, se realizaron 9 puntos de muestreo georreferenciados, los cuales fueron identificados previos a un trabajo de gabinete, y seleccionados de acuerdo a su cercanía con los puntos de muestreo de suelo, que presentaron distintos tipos de fisonomía. Se implementó el Método de Line Intercept o Transecta de puntos (Candfield, 1941;Evans y Love, 1957;Daget y Poissonet, 1971) de 30 m, donde se llevó a cabo un registro por cada metro. A través de este método se midió la cobertura vegetal, suelo desnudo y cobertura por tipo biológico y cobertura por especie. ...

... In order to define the optimal load of grazing animals necessary for the maintenance of each type of seminatural grassland identified, the pastoral value (PV) was calculated. It is expressed by the formula: PV = 0.2 × ΣSPC i × SI i , where SPC i is the specific presence contribution of the i-th species (as a percentage), while SI i is the specific index, ranging from 0 to 5, of the same species [101][102][103][104][105][106][107]. For the SPC, we applied the method based on the "visual estimation" of the degree of coverage, proposed by several authors [108][109][110][111]; for this purpose, we used the cover values detected during the botanical survey. ...
