Koh Sdach yellow seahorse monitoring, 2014–2021

Findings

• Five Koh Sdach sites were monitored during 2014–2021. Mean seahorse density was low (0.0008 ± 0.0001 individuals/m²); the authors found no significant temporal change in this dataset.
• Visits were irregular. A non-significant trend does not establish that the wider population is stable. Abstract p.48; methods pp.50–52.

How the evidence was collected

Five Koh Sdach sites were surveyed at irregular intervals between December 2014 and April 2021. Compare survey effort as well as sightings. The map currently shows the study area; individual visits and transects are not integrated.
