Saltholm's vegetation is dominated primarily by grasses, with its landscape consisting mainly of flat chalk meadowlands and coastal meadow.
There are few trees on Saltholm, clustered mainly in two places in the north and south-west of the island.
The island has a rich variety of flora, notably motherwort (Leonurus cardiaca), henbane (Hyoscyamus niger), blue iris (Iris spuria) and chickweed.

Saltholm is a protected nature reserve for wild birds which nest in large numbers on the island.
The southern part of the island, an extensive salt marsh, is protected under the Ramsar Convention and the island as a whole, along with the surrounding area of sea, has been designated a nature reserve by the European Union.
Mussel beds, eel grass, snails, crustaceans and fish in the shallow waters around the island provide an important food source for water birds.
Because of its importance as a wildlife sanctuary, access to Saltholm and its surrounding waters is strictly controlled.
Access to the island is via a small harbour at Barakkebro, at the north end of Saltholm.

The island is Denmark's largest grazing area for geese, some 7,000 of which visit during the summer.
Around 3,500 juvenile swans also live on the island in the summer, with some 2,000 wintering there.
10,000–12,000 ducks breed and graze on Saltholm during autumn and late winter/spring.
Saltholm is also home to Europe's largest breeding colony of eiders; 15,000 live on the island during the spring and some 7,000–8,000 are hatched on the island each year.
