Multi-scale Integration of Landscape Features with Plant and Water Quality Indicators

This website details an implementation program for monitoring Texas seagrasses following protocols that evaluate seagrass condition based on landscape-scale dynamics, including a hierarchical strategy for seagrass monitoring in order to establish the quantitative relationships between physical and biotic parameters that ultimately control seagrass condition, distribution, and persistence.

Acquisition of data at all stations from July to October 2011, 2012, and 2013 will provide an important temporal component to this unique data set, the first of its kind for the Texas coast. Summer 2013 sampling commences in July and extends to October. We are now working with The Nature Conservancy to incorporate seagrasses into their statewide Blue Carbon InVEST GIS model.

This project is conducted by scientists and graduate students at The University of Texas Marine Science Institute (data collection and synthesis) and The University of Texas at Austin Center for Research in Water Resources (Tim Whiteaker, data management) under the direction of Dr. Ken Dunton. Starting in summer 2013, all field work and data collection is being overseen by Sara Wilson. All data are collected, processed and synthesized with funding provided by several sponsors (listed below). Please contact Ken at ken.dunton@utexas.edu or Sara at sara.wilson@utexas.edu with questions or comments.

Monitoring Plan

  • Tier 1: A remote sensing component (typically at 1:24,000 resolution) for status and trends mapping that is regularly updated at about five-year intervals.
  • Tier 2: A regional rapid assessment program using fixed stations sampled annually from a shallow-draft vessel; high resolution photoimagery analysis for deep edge delineation.
  • Tier 3: An integrated landscape approach that includes permanent stations and transects that are aligned with high resolution photoimagery to examine the presumptive factors associated with changes in seagrass maximum depth limits and patchiness.
