    Abstract
    Successful postfire reseeding efforts can aid rangeland ecosystem recovery by rapidly establishing a desired plant community and thereby reducing the likelihood of infestation by invasive plants. Although the success of postfire remediation is critical, few efforts have been made to leverage existing geospatial technologies to develop methodologies to assess reseeding success following a fire. In this study, Terra Moderate Resolution Imaging Spectroradiometer (MODIS) satellite data were used to improve the capacity to assess postfire reseeding rehabilitation efforts, with particular emphasis on the semiarid rangelands of Idaho. Analysis of MODIS data demonstrated a positive effect of reseeding on rangeland ecosystem recovery, as well as differences in vegetation between reseeded areas and burned areas where no reseeding had occurred (P<0.05). We conclude that MODIS provides useful data to assess the success of postfire reseeding./Esfuerzos exitosos de resiembra post-fuego pueden ayudar a los ecosistemas de pastizales para regenerarse rápidamente, estableciendo una comunidad deseable de plantas y reduciendo la probabilidad de infestación de plantas invasivas. Mientras el éxito del mejoramiento post-fuego es crucial, pocos esfuerzos se han hecho para aprovechar las tecnologías geospeciales existentes para desarrollar metodologías encaminadas a medir el éxito en la resiembra después de la presencia de fuego. En este estudio, información de satélite Terra Moderate Resolution Imaging Spectroradiometer (MODIS) se usó para mejorar la capacidad de determinar los trabajos de rehabilitación post-fuego, con un particular énfasis en los pastizales semiáridos de Idaho. Análisis de información de MODIS demostraron un efecto positivo de resiembra en la recuperación de los ecosistemas depastizales así como en diferencias en vegetación entre áreas resembradas y áreas quemadas donde la resiembra no ha ocurrido (P<0.05). Se concluyó que MODIS provee información útil para determinar el é́xito de las resiembras post-fuego.
