Fall 2018 plant monitoring survey -- biomass calculated from shoot height and flowering status of plants in permanent plots at GCE sampling sites 1-10. Georgia Coastal Ecosystems LTER Data Catalog (data set PLT-GCEM-1811b; http://gce-lter.marsci.uga.edu/data/PLT-GCEM-1811b) B. Accession Number: PLT-GCEM-1811b C. Description 1. Originator(s): Name: Steven C. Pennings Address: Department of Biology and Biochemistry University of Houston Houston, Texas 77204-5513 Country: USA Email: scpennin@central.uh.edu 2. Abstract: The biomass of plants surveyed in permanent plots at 10 GCE LTER sampling sites in October 2018 was estimated based on allometric relationships between biomass and shoot height and flowering status derived for each site, zone, and species in October 2002 and October 2008. Biomass was calculated for dominant species, including Spartina alterniflora, S. cynosuroides, Juncus roemerianus, and Zizaniopsis miliacea, as well as rarer species including Scirpus spp, Panicum spp. And Typha angustifolia. This data set is based on GCE plant monitoring survey data set PLT-GCEM-1811a, and allometric relationships were based on GCE data sets PLT-GCEM-0211b, PLT-GCEM-0711, and PLT-GCEM-2011. 3.

Objectives: The research proposed for GCE-III is designed to address how variations in salinity and inundation, driven by climate change and anthropogenic factors, affect biotic and ecosystem responses at different spatial and temporal scales, and to predict the consequences of these changes for habitat provisioning and carbon (C) sequestration across the coastal landscape. 5. Abstract: The Georgia Coastal Ecosystems (GCE) LTER is located along three adjacent sounds on the Atlantic coast and includes both intertidal marshes and estuaries. Long-term drivers of climate change, sea level rise and human alterations of the landscape will cause transitions in dominant habitat types (state changes) within the GCE domain by changing the amounts and patterns of water delivery across the landscape. These changes in water delivery can be conceptualized as presses and pulses in river inflow, local runoff, groundwater input, and tidal inundation, which will in turn manifest themselves as changes in salinity and inundation patterns in the domain. The research proposed for GCE-III is designed to address how variations in salinity and inundation, driven by climate change and anthropogenic factors, affect biotic and ecosystem responses at different spatial and temporal scales, and to predict the consequences of these changes for habitat provisioning and carbon (C) sequestration across the coastal landscape. The goals are to: 1) Track long-term changes in climate and human actions in the watershed and adjacent uplands, and evaluate the effects of these drivers on domain boundary conditions. 2) Describe temporal and spatial variability in physical, chemical, geological and biological, and to evaluate how they are affected by variations in river inflow and other boundary conditions. 3) Characterize the responses of three dominant habitats in the domain to pulses and presses in salinity and inundation. 4) Describe patterns of habitat provisioning and C sequestration and export in the GCE domain, and to evaluate how these might be affected by changes in salinity and inundation. These efforts will be synthesized into a synoptic understanding of both biotic and ecosystem responses to variations in salinity and inundation driven by climate change and human activities, which will be used to assess thresholds between habitats and the potential for state changes in the domain. 6.

Climate: Climate summary for Sapelo Island, Georgia, based on NWS data from 1980-2010: Daily-aggregated Values: Mean (sample standard deviation) mean air temperature: 20.09°C (7.28°C) minimum air temperature: 15.02°C (7.96°C) maximum air temperature: 24.82°C (6.98°C) total precipitation: 3.26mm (10.3mm) Yearly-aggregated Daily Values: Mean (sample standard deviation) total precipitation (1980-2010): 1124mm (266mm) 2. Experimental or Sampling Design a. Design Characteristics: A quadrat survey was conducted in October 2018 to measure the species and size distribution of plants in the permanent plots at 10 GCE LTER sampling sites. b. Permanent Plots: Permanent plots were established in the marsh areas at each GCE sampling site in October, 2000. Each site was divided into two nominal zones based on marsh structure -- creek zone and high marsh -- and eight plots were randomly located in each zone and marked with stakes. Plots are visually inspected prior to each annual survey for signs of disturbance by wrack inundation, wildlife activity, and creekbank erosion. Plots lost due to catastrophic disturbance are replaced with new plots in different locations within the same marsh zone, which are assigned distinct plot numbers. (See history of plot disturbance in the site description section for details). c. Data Collection Duration and Frequency: A stratified random quadrat sampling design was used to determine the species and size distribution of plants in two nominal marsh zones (creek and high marsh) at each GCE LTER sampling site. Beginning of Observations: Oct 12, 2018 End of Observations: Oct 23, 2018 3. Research Methods a. Field and Laboratory Methods: Method 1: Method 1 -- Quadrat sampling -- Quadrats were randomly placed within two nominal marsh zones at each site (eight plots per zone) to create permanent plots in October 2000. These plots were used for this study, in addition to 5 new plots added in October 2001, 2 new plots added in October 2002, 5 new plots in October 2003, 8 new plots in October 2010, 1 new plot in October 2012, 14 new plots in October 2013 and 5 new plots in October 2015 to replace original plots lost due to catastrophic disturbance. The quadrats were marked using PVC or wooden stakes and varied in size, measuring 0.5m by 0.5m, 1m by 0.5m, or 0.25m by 0.25m, as indicated in the "Quadrat_Area" data column. Method 2: Method 2 -- Plant measurement -- The taxon, shoot height, and flowering status was recorded for each live shoot > 10cm in height present in each quadrat. Method 3: Method 3 -- RTK-GPS Survey of Permanent Plot Locations -- A survey was performed in April 2010 to measure the precise geographic locations and elevations of long-term plant plots at GCE-LTER marsh study sites 1-10. The survey was performed using a Trimble R6 real-time kinematic GPS sytem with Global Navigation Satellite System (GLONASS) support. The base receiver was placed on a permanent cement base installed near each field site, connected to GLONASS satellite services via mobile 3G Internet connection, and allowed to establish a stable benchmark positional fix prior to the survey. A portable wireless rover unit was then used to collect and log horizontal position and vertical elevation data on the ground at the center of each plot. Data were then corrected and analyzed using Trimble Geomatics Office software to determine latitude, longitude and elevation, and plant plot locations were then registered in the GCE-LTER geographic database. Location, Longitude and Latitude columns were then added to the data table based on matching site, marsh zone and plot number of each record to the corresponding plot identifier in the geographic database. For plots that were lost due to catastrophic disturbance prior to 2010 and replaced, the measured location of the the replacement plots were used to provide estimated positional information for the legacy plots, and the estimated values were flagged and the level of uncertainty was described based on the number of times the plot was replaced prior to RTK-GPS survey. Method 4: Method 4 -- Biomass Calculation -- Plant biomass was calculated for predominant flowering plants based on the allometric relationships between plant height, flowering status and biomass calculated by site, zone and species using the formula: ln(Biomass) = constant + htslope*ln(Plant_Height) + flslope*ln(Flowering_Status) b.
