This study examined long-term changes in ground height using Surface Elevation Tables (SETs). Measurements were taken in the floodplains of the Cache River at Buttonland Swamp in southern Illinois. The sites where data was collected included Crawford Tract and Eagle Pond from 2020-2022 and Deer Pond and Snake Hole from 2005-2022.

Soil samples were collected from Lady Bird Johnson Lake, Austin, Texas in 2019 to generate seed bank data for the rare plant Physostegia correllii. Seed germination data was produced from the soil samples kept in a greenhouse at the Wetland and Aquatic Research Center in Lafayette, LA.

Recurring drying and wetting events are likely to increase in frequency and intensity in predicted future droughts in the central United States and alter the regeneration potential of species. We explored the resistance of seed banks to successive droughts in 53 sites across the nine locations in baldcypress swamps in the southeastern United States. Along the Mississippi River Alluvial Valley and northern Gulf of Mexico, we investigated the capacity of seed banks to retain viable seeds after successive periods of drying and wetting in a greenhouse study. Mean differences of species richness and seed density were compared to examine the interactions of successive droughts, geographical location and water regime....

The decline of Taxodium distichum, bald cypress, forests along the Gulf Coast of North America is partly due to elevation loss and subsequent flooding. In many coastal wetlands, a common approach for coastal restoration is to rebuild elevation through the application of dredge spoil, but this technique has not been used widely in coastal forests due to concerns of negatively impacting trees. This experiment explored health responses of Nyssa aquatica, water tupelo, and T. distichum saplings to applications of low salinity dredge spoil in a greenhouse setting. Compared to controls, saplings of T. distichum grown in 7 and 15 cm sediment depths had higher final heights, and stem and total biomass while N. aquatica...
