Abstract:
Peatlands play an important role in carbon (C) storage and are estimated to contain 30% of global soil C, despite occupying only 3% of global land area. Historic management of peatlands has led to widespread degradation and loss of important ecosystem services including C sequestration. Legacy drainage features in the peatlands of northern Minnesota were studied to assess the volume of peat and the amount of C that has been lost in the ~100 years since drainage. Using high-resolution Light Detection and Ranging (LiDAR) data, we measured elevation changes adjacent to legacy ditches to model pre-ditch surface elevation, which were used to calculate peat volume loss. We established relationships between volume loss and site characteristics from existing geographic information systems (GIS) datasets and used those relationships to scale volume loss to all mapped peatland ditches in northern Minnesota (USA). This data publication includes a geodatabase containing a feature class describing peatland distribution in two of Minnesota’s ecological provinces (Laurentian Mixed Forest and Tallgrass Prairie Parklands), study sites used in Krause et al. (2021), and a feature class classifying ditches that coincide with peatlands in the study area by predicted volume loss per meter of ditch length based on statistical relationships between volume loss and site characteristics. Also included are the model outputs for the elevation profiles used to estimate total peat volume loss for a given ditch transect and the associated site characteristics. This information was compiled between October 2019 and November 2020 using publicly available datasets.
Purpose:
Data were collected and analyzed to assess the historic impact of drainage ditches on peat volume, from which we calculated an approximate associated carbon loss.

Attribute_Accuracy:
Attribute_Accuracy_Report:
The data included in this package rely on publicly-available datasets. As such, attribute accuracy information can be collected by referencing the individual datasets used, listed in the source information section. For accuracy information pertaining to our predictions of peat volume loss, please see Krause et al. (2021).
Logical_Consistency_Report:
The data are logically consistent. The consistency was verified as part of the quality assurance that occurred during data analysis.
Completeness_Report:
To the best of our knowledge, these data are complete and not missing any components. We excluded the Prairies Parklands and Eastern Broadleaf Forest ecological provinces of Minnesota. Whereas peatlands cover ~21% of the combined area of the Laurentian Mixed Forest and the Tallgrass Aspen Parklands provinces, lower initial peatland density combined with land use changes following European settlement result in a much smaller area of peat-forming ecosystems in the Prairie Parklands and Eastern Broadleaf Provinces.

There are no data for site 22 and 34 because after those sites had been selected, we identified bad DEM-matching between tiles at these two sites, which affected the elevation profiles we were able to create.

STUDY DESIGN
Sixty nine study sites were used to calculate peat volume loss in the ditches of northern Minnesota. Four transects used for each "Across" and "Control" study site, 8 transects used for each "4 corner" study site. LiDAR elevation data from 2008-2012 were used to generate elevation profiles for each transect. For each elevation profile, we identified a point on each side of the ditch where the elevation data deviated significantly from the surrounding landscape. The area between these two points represents the area in which the ditch is hypothesized to have caused a change in surface elevation and is referred to as the ditch effect zone. Using just the elevation data from outside the ditch effect zone (ie the undisturbed landscape), we modeled a pre-ditch surface, testing linear, 2nd, and 3rd order polynomial fits of a line. The residual area between the modeled pre-ditch surface and the observed elevation data in the ditch effect zone represents the peat volume loss. This process resulted in peat volume loss measurements from elevation profiles from 294 transects. We established statistical relationships between volume loss estimates from each transect and site characteristics from SSURGO, slope, and climatic variables using a generalized linear mixed effects decision tree. Using the volume loss values predicted from this statistical process, we classified ditches that coincide with our peatland layer (based on an intersection of SSURGO Histosols and the Minnesota NWI) by predicted volume loss. All data were obtained from publicly-available datasets SSURGO, NWI, LiDAR elevation data for Minnesota, PRISM climatic data (see source information section for more details). Data were accessed and processed between October, 2019 and November, 2020.

For elevation profiles and analysis of volume change - Using 3D Analyst tools and 1 m LiDAR data in ArcGIS, an elevation profile was created by plotting elevation versus distance on a scatterplot for each transect. We plotted and inspected each elevation profile in Excel 2019 to determine a point on either side of the ditch midpoint that deviated from the trend of the surrounding landscape. The area between the two deviation points is referred to as the ditch effect zone. Using only the elevation data from beyond the ditch effect zone, we tested linear, second-order, and third-order polynomial fits of a line to model the pre-ditch elevation above the ditch effect zone.

Using the regression equation output from the modeled fit of the line, we found the predicted elevation value for all points within the ditch effect zone. To calculate total volume change along the length of a transect, we subtracted the observed elevation value from the predicted pre-ditch elevation value. These differences were summed for a total volume change estimate for each transect, which represents the total volume change given one meter of ditch length. Given the similarity between the values measured with the three tests; the dominance of concave or convex land surfaces, i.e, with only one inflection point; and the convention of using the lowest-order polynomial fit to limit bias, we chose the second-order polynomial fit of a line to estimate all volume change with the transect method.


Study Locations Feature Class:
These points were created using the MNDNR NWI Wetland Finder (Kloiber et al. 2019) and the MNDNR topography tool, MN TOPO (MNDNR 2014), to examine summer imagery and contour lines across the ditch network to select 69 sites for pre-ditch surface estimation based on visual estimations of the surrounding continuity of the peatland. This was done to avoid the confounding influence of topographic variation caused by interspersed upland features on our pre-ditch surface estimation model. Fourteen sites are controls with no ditches present (referred to as “Control”), 33 are single ditch sites (“Across”), and 22 sites have two ditches that intersect (“4-corner”).

Residuals are summed below for total volume loss for each fit. Orange portions of the graph are those portions unaffected by the ditch, blue represent the ditch effect zone. Each worksheet name corresponds to one row on the summary worksheet.

It is important to note that within these worksheets summary information or equation details might be included within the data fields. Midway through the worksheet, predicted elevation data based on the regression equation from each fit of a line is used to calculate volume change from observed elevation in the ditch effect zone.
