| Summary: | allocating large amounts of energy to sexual reproduction. along the Texas and Louisiana Gulf coasts. Fire is used in americanus may respond to cataclysmic disturbance events by americanus. All in situ observations were considered americanus. The study was conducted along the upper Texas approximately II 0 km southwest of Houston, Texas. Foliar Areas used by LSG had decreased foliar cover, height, and areas were no longer different from controls after one year. can approach pre-disturbance levels within a year. S. coasts. S-. americanus is an important food source for comparable to plants naturally re-established in situ cover, canopy height, and stem density were measured for two designed to evaluate the influence of fire and LSG herbivory Development of shoots, tillers, and rhizomes of Disturbed areas had larger Sciipus americanus seed banks Disturbed plants also produced more germinable seeds. Cold during the first year. Plants grown in vitu attained experimentally grown S. americanus plants was also evaluated. following fire or LSG herbivory. Results suggest recovery of Germination of field collected seeds was ascertained. Number Gulf coast on the San Bernard National Wildlife Refuge heights, stem densities, and below-ground development herbivory. Seed numbers per stem and per @ were determined. lesser snow geese ( Chen aerulescens caeruiescens) (LSG) management purposes may be feasible, further research is needed, since seedlings have not been observed in natural occurs in coastal marshes along both Atlantic and Pacific of seeds nf2 of soil was used to estimate the seed bank of S. on growth, development, and reproduction of SciEpus Re-establishment of S.. americanus from seed may produce relative to areas subjected to fire and/or LSG herbivore. SciMus americanus is a perennial, rhizomatous herb which Scirpus americanus stands following fire and LSG herbivory Seed production per stem increased due to disturbance. stands usable by geese after one growing season; however, stands. stem densities.
