These data represent the raw data from the paper “The invasion of Japanese hop (Humulus japonicus) in a restored floodplain forest” published in Invasive Plant Science and Management by Annie H. Huang and Jeffrey W. Matthews.

These data represent the raw data from the paper “Evaluating the ability of wetland mitigation banks to replace plant species lost from destroyed wetlands” published in Journal of Applied Ecology in 2023 by Stephen C. Tillman and Jeffrey W. Matthews.

Data inputs, and scripts for the analysis detailed in Bradshaw et al, published in PlosONE 2020.

This is the dataset used in the Landscape Ecology publication of the same name. This dataset consists of the following files: NWCA_Int_Veg.txt NWCA_Reg_Veg.txt NWCA_Site_Attributes.txt NWCA_Int_Veg.txt is a site and plot by species matrix. Column labeled SITES consists of site IDs. Column labeled Plots consist of Plot ID numbers. All other columns represent species abundances (estimates of percent cover, summed across five plots). NWCA_Reg_Veg.txt is a site by species matrix of species abundances. Column labeled SITES consist of site IDs. All other columns represent species abundances (estimates of percent cover within individual plots). NWCA_Site_Attributes.txt is a matrix of site attributes. Column labeled SITES consist of site IDs. Column labeled AA_CENTER_LAT consist of latitudinal coordinates for the Assessment Area center point in decimal degrees. Column labeled AA_CENTER_LONG consist of longitudinal coordinates for the Assessment Area center point in decimal degrees. Column REFPLUS_NWCA represents disturbance gradient classes including MIN (minimally disturbed), L (least disturbed), I (intermediate), M (most disturbed). Column REFPLUS_NWCA2 represents revised disturbance gradient classes based on protocols described in the article. These revised classes were used for analysis. Column labeled STRESS_HEAVYMETAL represents heavy metal stressor classes, used to ascertain which wetlands were missing soil data. Classes in the STRESS_HEAVYMETAL column include Low, Moderate, High, and Missing. Sites with Missing STRESS_HEAVYMETAL classes were removed from analysis. More information about this dataset: All of the data used in this analysis was gathered from the National Wetlands Condition Assessment. Wetland surveys were conducted from 4/4/2011 to 11/2/2011. The entire National Wetlands Condition Assessment Dataset, which includes 3640 unique taxonomic identities of plants, can be found at: https://www.epa.gov/national-aquatic-resource-surveys/data-national-aquatic-resource-surveys

This is the core data for Zinnen et al., "Functional traits and responses to nutrient and mycorrhizal addition are inconsistently related to wetland plant species’ coefficients of conservatism." This is submitted to Wetlands Ecology and Management. Two datasets are submitted here. The first is greenhouse-collected data of 9 plant traits and concurrent treatment responses of Illinois wetland plant species. The second are field-collected leaf trait data of Illinois wetland plant species. These data are analyzed in the paper. Please refer to the main manuscript to see how these data were produced and specific analyses.

This is the dataset used in the Ecological Applications publication of the same name. This dataset consists of the following files: Internal.Community.Data.txt Regional.Community.Data.txt Site.Attributes.txt Year.Of.Final.Bio.Monitoring.txt Internal.Community.Data.txt is a site and plot by species matrix. Column labeled SITE consists of site IDs. Column labeled Plot consists of Plot numbers. All other columns represent species relative abundances per plot. Regional.Community.Data.txt is a site by species matrix of relative abundances. Column labeled site consists of site IDs. All other columns represent species relative abundances per site. Site.attributes.txt is a matrix of site attributes. Column labeled SITE consists of site IDs. Column labeled Long represents longitude in decimal degrees. Column labeled Lat represents latitude in decimal degrees. Column labeled Richness represents species richness of sites calculated from Regional Community Data. Column labeled NAT_COMP_REST represents designation as a randomly selected natural wetland (NAT), compensation wetland (COMP) or reference quality natural wetland (REF). Column labeled HQ_LQ_COMP represents designation as high quality (HQ), low quality (LQ) or compensation wetland (COMP). Column labeled SAMPLING_YEAR_INTERNAL represents year data used for analysis of internal β-diversity was gathered. Column labeled SAMPLING_YEAR_REGIONAL represents year data used for analysis of regional β-diversity was gathered. Column labeled TRANSECT_LENGTH represents length in meters of initial sampling transect. INAI_GRADE represents Illinois Natural Areas Inventory grades assigned to each site. Grades range from A for highest quality natural areas to E for lowest quality natural areas. Year.Of.Final.Bio.Monitoring.txt is a table representing years of final monitoring of compensation wetlands as mandated by the US Army Corps of Engineers. Column labeled Site consists of site IDs. Column labeled YR_FIN_BIO_MON consists of years of final monitoring. Entries of N/A represent dates that were unable to be located.

This is the dataset used in the Journal of Ecology publication of the same name. It is a site by species matrix of species relative abundances. The file BH.veg.data.csv contains a site by species matrix of species relative abundance (percent cover across all sampling quadrats within site). Data under the heading Year refers to sampling periods. Year 1 refers to the first set of samples taken between 1997 and 2000, Year 2 refers to the second set taken between 2002 and 2005, Year 3 refers to the third set taken between 2007 and 2010, and Year 4 refers to the fourth set taken between 2012 and 2015. All sites met Critical Trends Assessment Program (CTAP) size criteria of being at least 2 ha in size with a minimum of 500 m2 of suitable sampling area. The data in file BH.site.location.csv contains Public Land Survey System ranges and townships in which specific sites were located. All sites were located within the U.S. state of Illinois.
