Data Release: Buttonland Swamp, SET data 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.

This data was divided into categories depending on if the tree was alive, dead, or a sapling. Emergent species' height, density, and richness was also recorded.

Two Surface Elevation Tables (SETs) in a tidal Taxodium distichum swamp at Hickory Point State Forest near Pocomoke City, Maryland were used to collect data on the height of the topographic surface established with respect to a local vertical datum. Annual root production over time was measured by collecting data on ingrowth into mesh root bags. Root bags were collected at 5 set locations within the study area and analyzed to determine the weight in grams of new root production per meter cubed each year. This...

The study was conducted on tidal freshwater swamp environments subjected to salinity intrusion at Hickory Point State Forest near Pocomoke City, Maryland. Root bags were collected at 5 set locations within the study area from 2013 to 2021 and analyzed to determine the weight in grams of new root production per meter cubed each year.

The measurements were used to produce data on tree canopy area and seeds produced per Taxodium distichum tree.

Each year the growth of the T. distichum trees was measured in terms of the ratio of that year's circumference to the previous year's circumference. Tree growth was measured until the year the tree died or the conclusion of the study in 2021.
