“…There are no long-term experiments in this eco-region to indicate whether burning at such frequencies would maintain or improve the health of this ecosystem in the long-term. If fire is used in these communities to regularly reduce mesquite and cacti, managers need to pay careful attention to stocking levels (Higgins, Kantelhardt, Scheiter, and Boerner 2007;Teague et al, 2008) and monitor recovery of key parameters to ensure there is full recovery after each burn before applying further burns to the same area.…”

Prescribed fire is used to reduce woody plant and cactus cover and restore degraded rangelands in the southern Great Plains, but little is known regarding the impact of summer fires. We evaluated the effects of summer fires applied as patch burns in continuously grazed rangeland in north Texas. Vegetation and soil responses were measured on patches burned within grazing units in the summers of 1998, 1999, and 2000 relative to that on adjacent unburned control areas in the same grazing units. Annual rainfall during the study was below average for six burns (1998 and 1999) and average or above for three burns (2000). If average rainfall preceded and followed summer burning, degradation was limited to a modest increase in bare ground which recovered to exceed unburned control levels within 2 years. However, when drought conditions preceded and followed burning, there was an increase in bare ground and the proportion of annual forbs and annual grasses at the expense of perennial grasses. These areas took 3-5 years to recover. Areas burned in any year did not recover until after a season of favorable precipitation. The degree of degradation was proportional to the severity of drought conditions. The fires reduced the cover of honey mesquite (Prosopis glandulosa Torr.), other shrubs and cactus (Opuntia spp.), which facilitated herbaceous recovery, mitigating the negative impacts of burning in summer and the increased herbivory on the burned patches. Increases in herbaceous species composition were positively related to woody plant and cactus reduction following fire treatment. Results suggest that summer burning may be an effective and low-cost means of controlling problem plants, increasing pasture heterogeneity, and reducing herbivore impact on intensively grazed patches. However, before the practice of summer burning can be advocated, research needs to determine if post-burn deferment will facilitate more rapid recovery through regulating herbivory after burning to increase the recovery of litter and herbaceous cover and restore desired herbaceous species composition and production.

“…The provisions of biodiversity conservation and ecosystem stability within rangelands maintain the ecological value of these ecosystems. Therefore, maintaining or restoring rangeland ecosystem health and resilience is a critical social imperative to ensure the future supply of the ecosystem services, which are vital for the future well-being of human societies [29]. Such services include provision of stable soils, reliable and clean supply of water, and the natural occurrence of plants, animals and other organisms to meet the aesthetic and cultural values, and to enhance the livelihoods of people living around rangelands [30].…”

La precipitación (P) es uno de los factores principales que explican la producción de biomasa en pastizales y matorrales. La ef iciencia en el uso de la precipitación (EUP), relación entre la producción de biomasa y la precipitación, permite el uso de paradigmas simples de modelos (Simple Ecological Sustainability Simulator o SESS) que pueden ser parametrizados con información meteorológica existente en el país. La relación EUP-Precipitación se analizó de acuerdo con la evidencia experimental disponible, estableciéndose la relación matemática congruente con esta evidencia, a efecto de replantear la relación que se usó en el modelo SESS. Para parametrizar la EUP en función de índices de vegetación, se analizó un ejemplo en Coahuila, México, de corridas del modelo SESS y de estimaciones del índice NVDIcp a través del uso de imágenes del sensor AVHRR, para establecer relaciones funcionales entre la EUP espectral (NDVIcp/P) y la biomasa verde estimada con el modelo SESS. Al f inal se discuten opciones de desarrollo para enfoques de integración de modelos y sensores remotos.
