Morfa Friog Monitoring Data 2018
Morfa Friog managed coastal realignment site situated on the Mawddach estuary was created when the flood embankment was breached in November 2015.
A methodology was established and baseline data collected during autumn 2018 to monitor the development of the saltmarsh vegetation on the site.

The data consists of;
• A fixed-wing drone survey of the site to collect high-resolution aerial photography, undertaken on the 5th September 2018.
• The generation of an accurate height model from the collected aerial photography.
• Capture of vegetation communities based on species dominance from the aerial photography and data collected in the field.
• The selection of three transects across the main site.
• Detailed survey of a series of randomly located 2×2 metre quadrats along the transects.
• Photographs of transects quadrats and features of interest.
