I have just added this to the map of places to fly your drone at Drone Scene:
Land owner permission requirements unknown.
Classed as a nature reserve but no signage to suggest flying is prohibited and not listed on Drone Assist either. Openly accessible to the public but be cautious to the myriad of birdlife in the area.
The originator declared that this location was not inside a Flight Restriction Zone at the time of being flown on 02/08/2022. It remains the responsibility of any pilot to check for any changes before flying at the same location.
