"Short range scans suggest this biome supports extensive biodiversity both above and below the surface." ― PDA, Dialogue

The Grassy Plateaus cover vast areas where the seafloor is too deep for Creepvines to take hold. As stated by the PDA, a wide variety of lifeforms populate them. They are generally one of the first biomes the player encounters in Subnautica. The four Grassy Plateau areas border the Kelp Forest, Mushroom Forest, Safe Shallows, Sparse Reef, Blood Kelp Trench, Crag Field, Crash Zone, Underwater Islands, and the Dunes.

Description

Grassy Plateaus are characterized by large, pillar-like structures seemingly formed by subaquatic hydraulic action or abrasion (erosion), smooth marine plains, and sandy terrain almost completely carpeted with Blood Grass, giving the Grassy Plateaus their distinctive name. While exploring the Grassy Plateaus, it is advised for new players to pay attention to their surroundings for groups of Biters and to stay far away from suspicious sand clouds, as Sand Sharks dwell abundantly in this biome. Tiger Plants, another hazard, can also be found here, most commonly beneath Wrecks and in crevices.

Besides the large abundance of resources such as Quartz, Limestone and Sandstone outcrops, this biome also features several small caverns, as well as entrances to the Jellyshroom Cave. This biome contains numerous wrecks that include useful Fragments for technology such as the Modification Station and Battery Charger.

There are currently four Grassy Plateaus areas on the map, and several Destroyed Lifepods within them.

Trivia

There are four different Grassy Plateaus in the Crater: southeastern, southwestern, northeastern, and northwestern.
Out of the 4 Grassy Plateaus, the southwestern area is the largest of the four.
The Grassy Plateaus shares borders with both Safe Shallows, all five Kelp Forests, both Mushroom Forests, the Dunes, the Blood Kelp Zone (Trench), the Sparse Reef, the Crag Field, the Crash Zone, the Jellyshroom Cave, and the Underwater Islands.
