Biological fire prevention method: Evaluating the effects of goat grazing on the fire-prone mediterranean scrub

The effect of goat grazing on the shrubby understory of a pine forest in Doñana Natural Park was evaluated using non-destructive measures of vegetation volume over a period of twenty-four months. After establishing grazing exclusion fenced plots 350 adult Payoyas goats were introduced. Vegetation wa...

After establishing grazing exclusion fenced plots 350 adult Payoyas goats were introduced. Vegetation was sampled before the introduction of goats and afterwards twice a year, using the point intercept method and thereby obtaining data of height, frequency, cover and biovolume of species. After two years the total biovolume of the vegetation of the ungrazed area had increased significantly by 32.9%, while at grazed area, vegetation biovolume decreased significantly by 23.1%, leading to a significant decrease in mean height of the species. Although the number of species remained unchanged throughout the study, significant changes in their relative abundance were found in grazed area. The different responses of scrub species to grazing can be used as a tool to control species sensitive to grazing in shrubby forested areas. Significant reduction of total biovolume due to a reduction in vegetation height will help to reduce fire risk, thus contributing to the conservation of Mediterranean woodlands and forests while also fulfilling an important role in the economic and social lives of the rural population of Mediterranean countries.Durante veinticuatro meses y con medidas no destructivas, se ha evaluado el efecto del pastoreo de cabras sobre el biovolumen del matorral del sotobosque de un pinar en el Parque Natural de Doñana. Tras establecer nueve cercados de exclusión al pastoreo, se introdujo un rebaño de 350 cabras adultas de raza Payoyas. La vegetación se muestreó utilizando el método punto- intercepción obteniéndose datos de altura, frecuencia, cobertura y biovolumen de las especies. Después de dos años, el biovolumen total de la vegetación del área pastada aumentó significativamente un 32,9%, mientras que en el área pastada la vegetación disminuyó significativamente un 23,1%, con una reducción en la altura media de las especies. Aunque el número de especies se mantuvo sin cambios durante todo el estudio, se encontraron cambios significativos en la abundancia relativa. La diferente respuestas de las especies de matorral al pastoreo puede ser utilizado como una herramienta para controlar y gestionar el biocombustible en las zonas forestales. Esta reducción significativa del biovolumen puede favorecer la reducción del riesgo de incendio, contribuyendo así a la conservación de los ecosistemas mediterráneos, además de contribuir en la vida social y económica de la población rural de la zona.Junta de Andalucía OG-052/07Instituto Nacional de Investigacion y Tecnologia Agraria y AlimentariaBiología Vegetal y Ecología2012info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfapplication/pdfhttps://hdl.handle.net/11441/107357https://doi.org/10.5424/fs/2012212-02289reponame:idUS.
