Abstract: Presence and abundance of plant species was determined at the six permanent monitoring transects within fifty-six GCE LTER hammock sites and five GCE LTER study sites in June-July 2007. Plant presence was determined by placing a 1 m x 1 m qaudrat at two meters from the upland border of the study site’s permanent monitoring transect and noting all species present. In the center of the quadrat, an additional 0.5 m x 0.5 m qudarat was placed to determine percent cover of each species. Plant height was also measured and recorded that the four corners of the 0.5 m x 0.5 m qudarat. 3. Study Type: Directed Study 4. Study Themes: Plant Ecology 5. LTER Core Areas: Populations 6.

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.

History of Land Use and Disturbance: GCE1 -- Oct 01, 2000: Permanent plots were established in two nominal marsh zones based on marsh structure -- creek zone and high marsh -- and eight plots were randomly located in each zone and marked with stakes. Oct 01, 2001: Plots were examined for signs of disturbance by wrack inundation, animal activity, and creek bank erosion. No significant disturbance was observed, and no plots were replaced. Oct 16, 2002: Plots were examined for signs of disturbance by wrack inundation, animal activity, and creek bank erosion. The following plots were disturbed by wrack (some have no shoots): C4, C5, C6, C7, C8. The following creekbank plots are on creekbank areas that are collapsing: C5, C6, C8. No disturbance by animal activity was observed and no plots were replaced. Oct 18, 2003: Plots were examined for signs of disturbance by wrack inundation, animal activity, and creek bank erosion. The following creekbank plots are on creekbank areas that are collapsing: C5, C6, C7 and C8. No disturbance by wrack or wildlife activity was observed, and no plots were replaced. Oct 25, 2004: Plots were examined for signs of disturbance by wrack inundation, animal activity, and creek bank erosion. The following plots were lost due to creekbank erosion, catastrophic wrack disturbance, or catastrophic wildlife activity: C7, C8. No disturbance by wrack or wildlife activity was observed, and no plots were replaced. Oct 21, 2005: Plots were examined for signs of disturbance by wrack inundation, animal activity, and creek bank erosion.

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: This study was designed to determine the presence and abundance of all plant species in the hammock and GCE study sites. Percent cover of each present species was used to establish abundance of the plants. Percent cover was made within quadrats placed 2 m from the upland border of the hammock at each transect. There are six transects on each hammock or GCE study site. b. Permanent Plots: Samples were taken at 2 meters from the upland border of the six permanent monitoring plots within each hammock and GCE site. The plots were chosen at each hammock site by randomly generating a point using ArcGIS software, ESRI, Version 9.x that fell within the GIS hammock polygon. The point was then moved to the nearest perimeter point and designated Point A. Points B-F were then equally spaced around the perimeter, moving clockwise from Point A. The distance of the location was calculated by dividing the perimeter of the hammock by six. For creating plots in the GCE sites, a predetermined length of upland was chosen and mapped. This was treated a similar way, diving the distance by six and randomly generating a Point A and spacing B-F equally around the perimeter. c. Data Collection Duration and Frequency: All plant species within the 1 m x 1 m quadrat placed 2m from the upland border of the transect were noted. Percent cover of each species was determined within a 0.5 m x 0.5 m quadrat placed within the 1 m x 1 m quadrat. Each species was counted independently to determine percent cover. Beginning of Observations: Jun 05, 2007 End of Observations: Jul 30, 2007 3. Research Methods a. Field and Laboratory Methods: Method 1: Percent Cover -- A quadrat was constructed out of pvc piping and measuring 0.5 m x 0.5 m which was then divided into 0.05 m x 0.05 m squares using fishing line forming a grid with 100 squares of equal size. Percent cover is determined by the presence of a plant species in one square. If the species is present in 10 squares, it has a 10% cover. Each species was counted independently from the other species present. Geographic locations were determined for each quadrat locations using a differentially-corrected subfoot accuracy GPS unit. Method 2: Plant species -- A quadrat was constructed out of pvc piping and measuring 1 m x 1m in order to determine plant species presence. Method 3: Shoot height -- The height of the plant species present at each corner of the 0.5 m x 0.5 m quadrat was measured in centimeters using a meter stick. b.

Data Anomalies: GPS coordinates for the six plots were not taken at the first GCE site sampled, GCE6, and therefore are missing from the data set. Four corner height measurements were not taken at PN_ii_18 plots B, C, D or HS_iii_19 plot D due to the plots being at the creek bank’s edge. Four corner height measurements were not taken at PN_ii_16 plot C due to the plot being underwater. Four corner height measurements were not taken at BN_i_9 plots B, C, BN_i_8 plot B, PN_vii_25 plot C, or PN_i_26 plot A due to the lack of vegetation from wrack disturbance. Four corner height measurements were not taken at PN_ii15 plots A, B, PN_i_13 plots B, C, BN_i_10 plots C, D, BC_i_6 plot A, GCE3 plots A, C, GCE4 plots C, D, E, or GCE9 plot C due to the lack of vegetation.
