This manual provides detailed information on how to map and monitor seagrass resource status and condition. Several alternative monitoring methods are detailed and the reader should decide which is appropriate to their needs. The manual is divided in chapters, which cover

  • The monitoring process and how to start (Chapter 2 & Chapter 3);
  • How to map the seagrass resource and how to design a monitoring plan (Chapter 4.). Examples of monitoring designs (intertidal fixed transects site, intertidal fixed point site, subtidal fixed single transect, subtidal spots in defined area, depth transects across a meadow) are presented to assist the reader. This section also considers how often to monitor, pre-monitoring preparation and safety issues to consider.
  • Having mapped the seagrass resource and chosen an appropriate design, Chapter 5 then provides step by step methods for monitoring seagrass status from setting up & relocating a monitoring site to the measures within a quadrat;
  • Finally Chapter 6 discusses methods for monitoring seagrass condition & resilience. Methods for monitoring Halodule seed banks is presented and other advanced techniques are discussed.
