Descripción
According to the REDD + Program, it is necessary to monitor, quantify and report the forest system status of protected areas. Having this in mind the objective of this work is to delimit the growing seasons of Chaco Semi-arid Forest (FCHS) in Copo National Park (CNP), Santiago del Estero, Argentina, in the 2000-2022 period using time series of NDVIMODIS., and to quantify their Seasonally Integrated Aboveground Net Primary Productivity (SI-ANPP), its trend, and Rain Use Efficiency (RUE), and relate them to integrated seasonal rainfall (SR). The NDVIMODIS time series and the 0.5 NDVIRATIO thresholds made it possible to delimit the growth season, and quantify the SI-ANPP of FCHS with high efficiency. Significant differences were found (T = -3.49; p = 0.0006) in the SI-ANPP of FCHS. The SI-ANPP evidences high sensitivity to negative anomalies of seasonal rainfalls. The nonlinear regression model obtained (R2 = 0.73; p < 0.0001) provides unedited information at the local level on the efficiency of the SI-ANPP in terms of the SR. Seasonal rainfall >700 mm could be considered a threshold (or boundary) in the efficient water use of FCHS. The large positive trend of SI-ANPP of the FCHS CNP in the period 2000-2022 (slope = 462.43; T = 25.64; p <0.0001) evidenced the high stability of the forest system. The results obtained reaffirm the importance of creating legally protected areas, such as national parks, for the preservation of forest systems in the region.
De acuerdo al programa REDD+, es necesario monitorear, cuantificar, e informar el estado de los bosques de las áreas protegidas. Con base a lo antes expuesto los objetivos de este estudio fueron, delimitar la estacionalidad del bosque Chaqueño Semiárido del Parque Nacional Copo, Santiago del Estero, Argentina (FCHS CNP) en el periodo 2000-2022 mediante series temporales NDVIMODIS. Cuantificar la Productividad Primaria Neta Aérea estacional integrada (SI-ANPP), su tendencia, y el uso eficiente del agua (RUE) y relacionarlo con las precipitaciones estacionales integradas (SR). Las series temporales NDVIMODIS y el umbral 0.5 NDVIRATIO posibilitaron delimitar la estación de crecimiento y cuantificar la SI-ANPP con elevada eficiencia. Fueron encontradas diferencias significativas (T = -3.49; p = 0.0006) en la SI-ANPP del FCHS CNP. La SI-ANPP evidencia sensibilidad a las anomalías negativas de precipitaciones estacionales. El modelo no lineal obtenido (R2 = 0.73; p < 0.0001) provee inédita información a nivel local sobre la eficiencia de la SI-ANPP del FCHS en función de las SR. La precipitación estacional >700 mm podría ser considerada umbral (o límite) en el uso eficiente del agua del FCHS. La elevada tendencia positiva de la SI-ANPP del FCHS CNP en el periodo 2000-2022 (slope = 462.43; T = 25.64; p <0.0001), evidencia una elevada estabilidad del sistema forestal. Los resultados obtenidos reafirman la importancia de la creación de áreas legalmente protegidas, como parques nacionales para la preservación de los sistemas forestales de la región.
