From: The Texas Journal of Science | Date: November 1, 2006| Author: | Copyright information

Abstract -- The purpose of this study was to determine the sample incubation time, surface area, depth of the soil sample and number of soil samples required to adequately estimate the seed bank of the Distichlis spicata (saltgrass) community, the most widespread of the salt marsh communities, in the Diamond Y Spring Preserve, north of Fort Stockton, Texas. The locally abundant but geographically rare and threatened puzzle or Pecos sunflower (Helianthus paradoxus) is found in this salt marsh community. Soil samples should be incubated for 6 to 8 weeks after cold stratification, ...
