The document outlines a two-year project by the University of Rhode Island to gather high-resolution spatial data on human uses of coastal ponds, including user surveys and shellfish population assessments. It describes methods for mapping and valuing these uses, such as intercept surveys and boat-based transect surveys, aiming to understand user interactions and impacts on the environment. The project also focuses on developing indicators for shellfish management and modeling potential impacts of human activities.

- 2. Overview Two-year project. Collect data in the summers of 2014 and 2015. High resolution spatial data concerning human use of the coastal ponds. Surveys of pond users to better understand how they use, experience, and value the ponds. Surveys of shellfish populations. Multiple goals. To collect robust spatial data of human uses and environmental conditions. Better understand current conditions Model proposals
- 3. Mapping and Modeling Human Uses What can be mapped and modeled? Spatial Basic physical footprint Intensity of the use Travel and operating patterns Temporal Seasonality (we will only do summer) Hours of day Tides and weather conditions Behavioral attributes of the use Potential conflicts Potential synergies Economic values
- 4. Methods for Mapping and Valuation Human uses (URI) Intercept surveys and mapping Boat based offset transect surveys (B-BOTS) Shellfish resource assessments and mapping (RI DEM) based upon results of B-BOTS and random sampling. Collecting all currently available geospatial data for the coastal ponds. Over 50 datasets thus far, including environmental, social and regulatory spatial data.
- 5. Methods: Intercept Surveys Short intercept surveys of people using the ponds. Boat ramps, marinas, kayak rental, mooring fields, anchored boats, and along shore. Dates and times for intercept surveys will be randomly selected to avoid bias. Selection of interviewees. Participatory mapping. Ask people to record their last trip and current trip. Route and place where they spent the most time. Other activities that enhance or degrade their experiences.
- 6. Methods: Intercept Surveys Attitudinal questions Parking Access Trash Various management options Economic and demographic questions Travel distances Trips per year Age Income ranges
- 7. Boat-Based Offset Transect Surveys
- 8. How it works. Transects lines will be laid out on each pond. A boat following the transects will be able to survey the entire pond. Randomly selected Days Time periods Order of transects Laser locator binoculars and GPS Measure the straight line distance & angle to every observation Calculate position of each observation
- 9. Recording Attributes in ArcPad
- 10. Recording Attributes in ArcPad The list of attributes will be updated based upon key informants and on-the-pond testing. Create a series of drop down choice menus that immediately appears when a record was created. The recorder would enter data by tapping. Record weather (temp., cloud cover, wind direction) and sea state every hour.
- 12. Putting it all together Examples Economic study can put values on various activities and then those values can be distributed across the ponds based on B- BOTS. The intercept survey can provide information about how users perceive interactions and B-BOTS can be used to map those interactions. Intercept mapping can be used to provide information about routes and destinations, while B-BOTS accurately maps overall usage of space. The RI DEM shellfish assessment and B-BOTS together will tell us about the human impact on shellfish.
