WEE01 Impacts of riparian and non-riparian woody encroachment on tallgrass prairie ecohydrology
Plant xylem water samples were collected from Cornus drummondii (rough-leaf dogwood), Andropogon gerardii (big bluestem), Quercus macrocarpa (bur oak), and Quercus muehlenbergii (chinquapin oak) during the summer of 2016. Soil cores were also collected during the summer of 2016 to collect soil water from the surface to 200 cm depth. Isotope values (δ18O and δ2H) were analyzed for each water sample to determine depth of plant water uptake.
PGL01 Litterfall collection in riparian gallery forest at Konza Prairie
Litterfall is collected monthly (more frequently during peak litterfall in October and November) at permanent sampling sites in the mixed deciduous gallery forest located along the lower reaches of Kings Creek at the Konza Prairie Biological Station. Thirty litterfall traps, 50 x 50 cm (.25 m2) are located along the north fork of Kings Creek, and two are located on the south fork of Kings Creek. The north fork boxes are numbered 31 to 60 and the south fork boxes are numbered 1 and 2. Originally, the south fork also had boxes 3 to 30 but these samplers were terminated in 1993 due to repeated damage by bison. (Boxes 1 and 2 are located just outside the bison area.) Samples are sorted in the lab, and mass of wood, seeds, and foliage are recorded separately.
Rio Icacos hyporheic and riparian chemistry
Hydrologic and chemical characteristics were determined for both riparian and hyporheic subsurface flow along a 100-m reach of a sandy-bottom tributary of the Rio Icacos in the Luquillo Experimental Forest, Puerto Rico. Hydrologic data (vertical hydraulic gradient and hydraulic conductivity of streambed sediments) and the topographic and morphological features of the watershed indicated diffuse inputs of groundwater from the near-stream riparian zone along this site. Cumulative groundwater discharge, determined by tracer dilution techniques, was ~1.5 L/s or 10% of the total stream discharge. Spatial heterogeneity in hydrologic and chemical properties of riparian and hyporheic sediments was large. Hydraulic conductivity explained much of the variation in NH4-N and dissolved organic carbon (DOC) concentrations, with highest concentrations in sites having low conductivity. A mass-balance approach was used to examine the influence of the near-stream zone on nutrient transport and retention. Outwelling riparian groundwater had the potential to increase stream N concentrations by up to 84% and DOC concentrations by up to 38% along our 100-m reach. Because stream concentrations were constant downstream despite this input, we conclude that significant N and C retention or loss were occurring in the near-stream zone. Lotic ecosystems and their associated riparian groundwater can have a quantitatively significant impact on the nutrient budgets of tropical headwater catchments.

Riparian and upland understory vegetation lifeforms and leaf-litterfall ordination analyses in the Luquillo Forest Dynamics Plot
Riparian areas are proportionally a small component of the forested landscape, they are significant contributors to ecosystem process, terrestrial and aquatic linkages, plant community composition, as well to basal energy resources for aquatic fauna. We describe vegetation and leaf-litterfall composition in relation to past land use in riparian and upland locations in tropical wet forest, Luquillo Forest Dynamics Plot (LFDP), Luquillo Experimental Forest, Puerto Rico. Data collected from 2003 to 2005. Stratified sampling was conducted in riparian and upland areas of LFDP with high and low past land use. Understory vegetation life-form composition were sampled in plots. \<para\> Support for this work was provided by grants BSR-8811902, DEB-9411973, DEB-9705814 , DEB-0080538, DEB-0218039 , DEB-0620910 , DEB-1239764, DEB-1546686, and DEB-1831952 from the National Science Foundation to the University of Puerto Rico as part of the Luquillo Long-Term Ecological Research Program.

Vegetation surveys in the riparian (bosque) corridor of the Middle Rio Grande valley, NM
This dataset contains vegetation cover information from 34 long-term Bosque Ecosystem Monitoring Program (BEMP) sites from 2000 – 2021. Data were collected along ten 30-m transects at each site at the centimeter scale each year in August-early October as funding and site access allowed. At the fullest extent, sites spanned 520 km of the riparian forest along the Rio Grande. The purpose of this dataset is to track plant species at sites along the Rio Grande in New Mexico. From this dataset, changes in plant species abundance, richness, and species diversity can be tracked and analyzed with ecosystem drivers such as flooding, fire, species removal/fuel reduction projects, and climate change. Species are coded using USDA Plant Database codes, allowing species information to be added to each species, including origin (native or nonnative), duration (e.g., annual, biennial, perennial), and plant type (e.g., grass, forb, vine, shrub, tree). This dataset has allowed the tracking of the ascendance of nonnatives in some sites, the recovery of natives in other sites, success or lack of success following restoration projects, and records of new species occurring in various counties and the state of New Mexico.

Distribution models for riparian landbirds and waterbirds in the Sacramento-San Joaquin Delta
<p><strong>SUMMARY</strong><br> Distribution models for 9 riparian landbird species and 6 groups of waterbird species in the Sacramento-San Joaquin River Delta of California. </p> <p><strong>DESCRIPTION</strong><br> These predictive models were developed to relate the probability of species or group presence as a function of the surrounding landscape, facilitating predictions of species presence or absence over the entire landscape. Each .RData object is structured as a list containing individual model objects of class `gbm` for each species or group.</p> <p>Models were developed using Boosted Regression Trees, implemented in R using the R packages `dismo` (Hijmans et al. 2021) and `gbm` (Greenwell et al. 2020). Models were developed from pre-existing bird survey data, including 2,547 surveys for riparian landbirds conducted at 716 unique locations throughout the Central Valley of California during the breeding season (May and June), 2011–2019, and 7,820 surveys for waterbirds conducted at 504 unique locations in the Delta during the fall (July 15–November 15) and winter (November 17–March 5) seasons, 2013–14 and 2014–15. Waterbird models were developed for each of the fall and winter seasons, with 46 species grouped into 6 distinct groups defined by similar habitat requirements, foraging style, and diet. </p> <p>These models were used to predict the distribution of each species and group across a baseline Delta landscape (representing land cover in 2018), and these predictions were used to identify Priority Bird Conservation Areas in the Delta. In addition, the models were used to predict distributions for alternative scenarios of future landscape change, and to evaluate the net change from the baseline distributions in the total area of suitable habitat. These models are required for evaluating the change in Biodiversity Support benefits using the R package "DeltaMultipleBenefits", which provides the code and work flow for repeating the initial scenario analyses or analyzing new scenarios.</p> <p>For additional details about the development and applications of these data, please see: </p> <ul> <li>Dybala K, Sesser K, Reiter M, Shuford WD, Golet GH, Hickey C, Gardali T.

Summer 2017 porewater and sediment geochemistry data at Second Creek, a sulfate-impacted riparian wetland in northeast Minnesota
Water and sediment chemistry data were collected over the summer and fall of 2017 at Second Creek, a riparian wetland study site near Aurora, MN, to understand sulfur and methane processes. Porewaters were collected with two distinct methods “peepers” (multi-chambered equilibrium dialysis samplers) that allow for high vertical resolution but 2-3 week averaged temporal resolution, and rhizon samplers that enable instantaneous temporal resolution but have lower spatial resolution. Porewaters were analyzed for dissolved cations, anions, sulfide, methane, iron(II)/iron(III), and pH. Sediment cores were analyzed for acid volatile sulfide, and sulfur and iron speciation via X-ray absorption spectroscopy.
Tree-ring width measurements and isotope data for riparian Populus species, Santa Clara River, 2019
This data set comprises tree-ring data collected from 114 cottonwood trees (Populus trichocarpa and Populus fremontii) within the floodplain of the Santa Clara River, CA. Tree-ring data include annual ring width measurements for all rings of each individual as well as semi-annual (earlywood and latewood) measurements of stable carbon and oxygen isotopes for pure alpha cellulose extracted from annual growth rings corresponding to calendar years 2010-2019 for a subset of 48 individuals. This data set is completed. Carbon and oxygen isotope ratios are reported using “delta” notation (i.e. δ13C and δ18O) calculated by the equation: δ13C (or δ18O) = (Rsample/Rstandard - 1) x1000 where R is the molar ratio of 13C/12C (or 18O/16O), with Rsample being that of tree ring cellulose and Rstandard that of Vienna Pee Dee Belemite (VPDB) for δ13C and Vienna Standard Mean Ocean Water (VSMOW) for δ18O. These data were used for the following publication: Williams, J., J.C. Stella, S.L. Voelker, A.M. Lambert, L. Pelletier, J.E. Drake, J.M. Friedman, D.A. Roberts, M.B. Singer. (2022).

Riparian remnant species registered at headwater streams in San Juan Zitácuaro, Mich.
Studying riparian vegetation allows understanding the floristic diversity patterns along the fluvial network, and because of the level of transformation they show, it is essential to generate knowledge to guide further recovery. This paper analyzed the remaining riparian tree vegetation in 30 sites in streams located in the Monarch Butterfly Biosphere Reserve, by describing the structure, species richness, and geographic setting (elevation, precipitation, hydrological order, and land cover), and by identifying possible invasive species. Elevation of the sites was associated with precipitation, hydrologic order, and land cover being crossed by the streams. Fifty-six mostly tree species were recorded, which increased in density and height with elevation. Some of the species with the highest importance value include Roldana angulifolia, Cestrum fulvescens, Ilex tolucana, Alnus acuminata, Buddleja cordata, and Fraxinus udhei. Four physiognomic groups emerged based on the number of species, genera and families, the number of branches, and the number, height, and diameter of individuals. High species turnover was found between sites, mainly with those located at higher elevations. The occurrence of potentially invasive species was shown to be associated with the density of individuals, with Shannon's diversity index (H'), and with geographic attributes such as elevation and hydrological order. The analyzed riverbanks show human intervention, being necessary to discriminate those impacts associated with flow alteration from those associated with land cover change.
Little Tennessee River Riparian Buffer change GIS data: 1998 - 2015
Using high resolution orthoimagery, riparian conditions between 1998 and 2015 were mapped and quantified in the rural upper Little Tennessee River basin in Macon County, North Carolina. Low elevation valley streams in residential areas were targeted, excluding stream segments on U.S. Forest Service (USFS) lands. Impoundments and streams within existing urban centers were also excluded from GIS analysis. Tributary streams were included if they were National Hydrography Dataset (NHD) mapped streams and if they met the study criteria, i.e. low-elevation residential valley streams outside existing urban areas and USFS lands. Due to the size of the watershed and time constraints, only the mainstem Little Tennessee and a portion of its tributary streams could be mapped. A total of 658 km (including both banks) of streams in the study area were mapped and classified. All classifications were made by one interpreter between June 2018 and August 2018. The GIS files are are in .zip archives labeled by imagery year (1998 and 2015). The 1998 GIS files are mislabeled '1999' which was corrected during analysis using R. The code used for analysis is provided in R markdown files.
Effects of drying temperature on potential carbon mineralization and water-extractable organic carbon in Iowa cropland and riparian buffer soils
Measuring carbon dioxide (CO2) produced after re-wetting a previously dried soil is an increasingly popular soil health assay, but there is disagreement on the optimal soil drying temperature. We tested whether soil drying temperature impacts water-extractable organic carbon (WEOC) and soil CO2 emissions (potential carbon mineralization) following rewetting of dried soil. Samples were collected at four sites in north-central Iowa, US, and each site had soils planted to corn/soybean or perennial vegetation. The dataset includes measurements of WEOC prior to the incubation experiment, and measurements of CO2 flux and its stable carbon isotope ratio over the course of a 28-day incubation. The manuscript describing these data is under review in Geoderma.
Summer 2016 hydrology and water chemistry data at Second Creek, a sulfate-impacted riparian wetland in northeast Minnesota
Hydrological and water chemistry data were collected at Second Creek, a riparian wetland study site near Aurora, MN, to understand sulfur and methane processes. Data were collected over the summer of 2016. Hydrological data were collected using temperature probes and pressure transducers installed in surface water gauges and shallow piezometers. Water chemistry was analyzed in surface water samples and porewater samples collected with “peepers” (passive diffusive samplers).

This dataset accompanies the Rohde et al. paper titled, Groundwater dependence of riparian woodlands and the disrupting effect of anthropogenically altered streamflow. The provided scripts process groundwater, vegetation, climate, and streamflow input data from various sources. Further, all output data and statistical analyses are included.
Riparian bryophyte list of the Andrews Experimental Forest, 1994/1995
The following bryophyte species list compiles habitat information based on the quantitative data collected from 360 samples (2 x 4 m quadrats) distributed among 42 sites within the Andrews Forest. The sites range from 420 m to 1250 m asl stream orders 1 to 5. The list comprises 131 taxa, 84 mosses and 47 hepatics. Many of the species were however infrequent and thus detailed and objective accounts of their habitat demands are difficult to provide. The data is specific for the studied sites but may serve as an indication of the general habitat demands of the species within the western Cascades and to some extent for riparian zones in the Coastal Mountain Range. Voucher specimens have been deposited at the herbaria Oregon State University and UME, Sweden.
Baltimore Ecosystem Study: Denitrification potential in riparian zones and streams
Denitrification potential and a series of ancillary variables (inorganic nitrogen concentrations, moisture content, organic matter content, microbial biomass carbon and nitrogen content, potential net nitrogen mineralization and nitrification, microbial respiration, root biomass) has been measured in riparian zone soils and stream geomorphic features by a series of undergraduate and graduate student researchers as part of the Baltimore Ecosystem Study since the early 2000s. These studies often center on the series of sites where there has been long-term monitoring (since 2000) of riparian water tables and groundwater chemistry along four first or second order steams in and around the Gwynns Falls watershed in Baltimore City and County, MD (https://doi.org/10.6073/pasta/f7721ec5a4fab5b031f8056824e07e7d). One site is in the completely forested Pond Branch catchment that serves as a "reference" study area for the Baltimore LTER (BES). Two sites (Glyndon, Gwynbrook) are in suburban areas of the watershed; one just upstream from the Glyndon BES long-term stream monitoring site in the headwaters of the Gwynns Falls, and one along a tributary that enters the Gwynns Falls just above the Gwynnbrook BES long-term stream monitoring site farther downstream. The final, urban site (Cahill) is along a tributary to the Gwynns Falls in Leakin Park in the urban core of the watershed. Other sites were used in different studies as described in the publications associated with each study. The different studies also varied in just which ancillary variables were measured.
Baltimore Ecosystem Study: Riparian vegetation data - 1 of 11 - 1999 and 2004 trees
This is one of 11 datasets generated in a study of riparian vegetation in the Baltimore Ecosystem Study from 1999-2004. Comparisons of vegetation between the rural/suburban (upper) and urban (lower) sections of the watershed show distinct patterns across an urban to rural gradient. In the lower, more urban section of the watershed, wetland tree species are either absent or occur as small stems while upland species are abundant, in mixed sizes. A comparison of the number of wetland and upland species in the mostly urbanized Gwynns Falls riparian zone with non-urbanized Piedmont floodplains throughout Maryland shows approximately twice as many upland species in the urban floodplain than in non-urbanized floodplains. The majority of shrubs in riparian zones through the Gwynns Falls are upland species. For herbaceous species, frequencies of upland and wetland species are about equal in the upper and middle regions of the watershed, but upland species are more common in the more urban lower floodplains by a factor of greater than two.
