How to visit seagrass coastlines without damaging the meadow

Seagrass can be harmed by anchoring, trampling, propellers and careless shallow-water access. A low-impact visit starts by treating the meadow as habitat rather than empty seabed.

01

The meadow is living structure, not spare sand

A seagrass bed can look like a patch of green beneath shallow water, but roots, rhizomes and leaves create three-dimensional habitat used by fish, invertebrates and other wildlife.

Dragging an anchor or repeatedly walking through a shallow bed can break plants and disturb the sediment that helps the meadow persist.

02

Low-impact choices are usually simple

Use designated channels and moorings when local managers provide them. In a small boat, avoid motoring across visibly shallow beds where a propeller can scar the meadow. In clear shallows, choose established entry points rather than cutting a new footpath through vegetation.

Rules differ by destination, so local marine-park, harbour or operator instructions should override a generic travel checklist.

03

Wildlife encounters still need distance

Seagrass meadows can support turtles, dugongs, manatees and juvenile fish. Seeing wildlife does not justify chasing it into a bed or blocking its route to feed.

A good visit leaves the meadow visually boring after you depart: no scar, no uprooted clump and no forgotten line or anchor.

Before you decide

Keep these five things with you.

  1. 01Use designated moorings where available
  2. 02Keep anchors out of visible seagrass
  3. 03Avoid propeller scars in shallow beds
  4. 04Use established access points
  5. 05Follow local wildlife and marine-park rules

Useful questions

Quick answers,
kept specific.

Is it okay to anchor in seagrass if the water is shallow?

Avoid it where possible and follow local rules. Anchors and chains can uproot plants and damage meadow structure.

Can I walk through a seagrass meadow at low tide?

Use designated access where available and follow local guidance. Repeated trampling is one of the physical pressures UNEP identifies.
