Reaches of salt marsh occur, but they are primarily near the Waterside Bridge (crossing of the A975 road) and the mouth of the Tarty Burn, a small tributary river.
There are hides to watch waders (best at low tide), and a wildfowling code of conduct with a voluntary refuge area south of the main bridge over the estuary (A975).
Quickly, by the time of reaching the first roadway bridge crossing about 1,300 metres (4,300 ft) up the estuary, there are mussel beds and marshy areas.
The broader landscape drained by the Ythan near the coast is a generally mild sloping farmland known as the Buchan plain, which is virtually devoid of trees.
Studies date the lithics recovered at least as early as 7000 BC, with most of the artefacts from the Ythan mouth area deriving from the Sands of Forvie.
[6] At the river mouth species of birds include scaup, long-tailed duck, red-breasted merganser and velvet scoter.
Meikle Loch is an element of the Ythan Estuary complex and sustains some aquatic vegetation, and from November to March is home to many wading birds, ducks and geese.
[8] The component landforms which are considered elements of the SPA or SSSI are the estuary itself, the dunes to the east known as the Sands of Forvie, Meikle Loch and the adjacent Kippet Hills.
