Rehabilitation of native forest through grazing rest and complementary use of exotic pasture in the Arid Chaco: case study in San Luis (Argentina)

The main activity of peasants in the Valle de Conlara is cattle grazing in degraded native forests. In similar regions, excluding cattle during rainy seasons allows for better conditions of the herbaceous layer and soil in forests. Complementary use of implanted pastures makes this possible.

In similar regions, excluding cattle during rainy seasons allows for better conditions of the herbaceous layer and soil in forests. Complementary use of implanted pastures makes this possible. The objective was to evaluate the effects of seasonal exclosure (vs. continuous) and complementary use of an exotic pasture, on forage biomass and quality, and soils. For two years, wet (842 mm/year) and dry (521 mm/year), three plots with a different treatment were monitored: forest with six years of summer exclosure, forest without exclosure, and Panicum coloratum pasture on a cleared site. The plot with exclosures vs. without exclosures had 2.5 times more native grass cover, 1.9 to 3.4 times more Aboveground Net Primary Production (dry and wet years, respectively), and four times more seed bank density. The soil had greater litter cover and infiltration capacity, lesser bare soil area, and higher percentage of C, P and N. The productivity of P. coloratum doubled native grasses in the rested forest. Using it during summer, allows the herbaceaous layer of the forest to rest and defers it towards the winter, maintaning better quality than the pasture.   La principal actividad de los pequeños productores del Valle del Conlara es la ganadería en bosques nativos degradados. En regiones similares, los descansos en la estación lluviosa mejoran la condición del estrato herbáceo. Complementar con pasturas implantadas posibilita dichos descansos. El objetivo fue evaluar el efecto del pastoreo con descansos estivales del bosque nativo (vs. continuo) y uso complementario de pastura exótica, sobre la biomasa y calidad forrajera, y el suelo. Durante dos años, húmedo (842 mm/año) y seco (521 mm/año), se monitorearon tres lotes con un tratamiento diferente: bosque con seis años de descansos estivales, bosque sin descansos y pastura de Panicum coloratum en un parche sin árboles. El lote con descansos vs. sin descansos, presentó 2,5 veces más cobertura de gramíneas nativas, 1,9 a 3,4 veces más Productividad Primaria Neta Aérea (año seco y húmedo, respectivamente) y cuatro veces más densidad de semillas en el banco. El suelo tuvo menor suelo desnudo, mayor capacidad de infiltración y porcentaje de C, P y N total. La productividad del P. coloratum duplicó la del pastizal del bosque descansado. Utilizarla en verano, permite descansar y diferir el estrato herbáceo del bosque al invierno, que mantiene mejor calidad que la pastura.
