Continuous flooding during the growing season rapidly reduced salinity. Intermittent flooding reduced salinity slightly, compared to the unflooded ridge sites. Managers can take advantage of this to favor more salt tolerant species such as Scirpus maritimus and discourage less tolerant species such as Typha spp. Species such as Typha, having wind d...

... The impacts of leaf litter are not feasible to mitigate at a large scale, as even removing litter for the purposes of this study was highly intensive. Prescribed burning has proven effective in some cases; however, it often results in not only increased species richness, but cattail vigour, presumably due to increased light availability and nutrient release (Smith & Kadlec 1985;Kostecke et al. 2004). Though not treatable at a large scale, preventative measures may be possible in certain instances, for example restoration projects such as Frenchies, where a habitat was heavily manipulated. ...
... We found that disturbance in the landscape associated with impoundment infrastructure, including roads and canals, was associated with less native perennial cover and species richness, a result that might be partially explained by the negative influence of hydrologic disturbance on propagule dispersal. Dams, ditching, and diking are known to disrupt seed dispersal, particularly for water transported seed (Nilsson et al., 2010) like those of many high-quality wetland perennials in GSL (Kadlec and Smith, 1984). Disturbance to the natural hydrologic regime associated with impoundment infrastructure might also reduce establishment opportunities by restricting drawdown conditions (Van Geest et al., 2005). ...
