These data were compiled to identify potential contributions of drought and inundation tolerance to vegetation composition along the Colorado River. Objective(s) of our study were to quantify physiological and growth responses of different plant species to drought and inundation. These data represent measurements taken on container plants in a greenhouse, and hydrological niche values based on field monitoring data that are published elsewhere. These data were collected in summer of 2022 at the Northern Arizona University Research Greenhouse Complex. These data were collected by Northern Arizona University and U.S. Geological Survey scientists in a greenhouse and laboratory setting. These data can be used to assess...

Impounded tidal conditions often compromise coastal marsh restoration goals, through vegetation loss and other biogeochemical feedbacks. To determine if episodic marsh impoundments could be partially responsible for the observed cordgrass (Spartina foliosa) dieback at Crissy Field, Golden Gate National Recreation Area, we examined sulfur chemistry and plant stress along transects between and during tidal inlet closure events from 2007 to 2008. During closures, porewater sulfide (PW S2−) concentrations did not respond consistently among sites, nor did they increase to levels likely to cause stress damage to cordgrass (>1 mM). However, sediment solid-phase total reduced sulfur (TRS) concentrations did respond strongly...
