Savanna

Lore & Background

In the world of Planet Zoo, the Savanna biome is a tribute to the African savanna ecosystem, one of the most recognizable and biodiverse grassland habitats on Earth. The game captures its essential character: wide-open plains where visibility stretches to the horizon, the iconic flat-topped acacia providing dappled shade, and a climate that swings between a lush green wet season and a parched, amber dry season. This seasonal rhythm is reflected in the game's weather and vegetation systems, so a well-designed savanna enclosure shifts with the in-game calendar.

The biome is home to some of the most beloved animals in the zoo. Lions patrol in prides, elephants move in matriarchal herds, and zebras and wildebeest form vast, shifting herds that would, in the wild, follow the rains across thousands of kilometres. Giraffes browse the high canopy of acacia, while rhinos and hippos anchor the landscape with their sheer presence. In Planet Zoo, housing these animals well means giving them space, social groups, and enrichment that mirrors the openness of their natural range.

For the player, the Savanna is often the first biome they build, and for many, the one they return to most. There is something deeply satisfying about shaping a wide, sunlit plain, planting a ring of acacia, adding a waterhole for the hippos, and watching a pride of lions lounge in the afternoon heat. It is the biome that most players associate with the core fantasy of Planet Zoo: creating a world where wild animals thrive in a setting that feels true to them.

In Their Own Story

The morning heat rolled off the grass in a slow, golden wave. A lioness lifted her head from the shade of a flat-topped acacia, ears swivelling toward the sound of hooves. Across the wide expanse of the savanna enclosure, a herd of zebras had begun their slow migration toward the waterhole, their black-and-white flanks rippling in the dry wind. An elephant matriarch stood at the edge of the watering hole, trunk raised, spraying a fine mist over her calves. The keeper, watching from the observation deck with a thermos of coffee, smiled. The savanna was alive, the animals were content, and for another day, the plain held them all.

Reader's Guide

The Savanna biome in Planet Zoo is an open, warm grassland habitat zone designed to house large, social, and grazing African species. It is one of the biomes available in the base game and is typically among the first players build.

Its role in the game is straightforward: it provides the environmental context that makes animals like lions, elephants, zebras, giraffes, rhinos, and hippos feel at home. The biome's terrain is characterised by flat to gently rolling grasslands, scattered acacia and umbrella trees, and a dry, warm climate with seasonal rain. Players can customise the vegetation density, add water features like watering holes or small rivers, and adjust the terrain to create natural sightlines and shelter.

Why it matters: the Savanna is the biome most associated with the 'big five' and large herds, making it a centrepiece for many zoo layouts. It contrasts sharply with the dense Tropical or the cold Tundra, giving your park visual and ecological variety. Getting it right—enough space, proper social groups, good sightlines, and seasonal variation—is what separates a mediocre enclosure from one that truly captures the spirit of the African plain.

Did You Know?

• The Savanna biome's seasonal system means the grass and tree foliage change appearance between the in-game wet and dry seasons, giving the same enclosure a noticeably different look at different times of year.
• Lions in Planet Zoo are social and will form prides when housed together, making the Savanna biome one of the few where you can realistically keep a full pride in a single enclosure.
• The acacia trees that define the Savanna's silhouette are a signature visual element of the biome and are instantly recognisable to players as the 'African plain' aesthetic.
• The Savanna is a base-game biome, meaning no DLC is required to access it, making it one of the most accessible habitats for new players.
