rimu whose red berries fed the forest floor

Size
Height: 3–5 m
Lifespan
500–800 years
Diet
Produces small, red-orange berries (fleshy cones) eaten by kererū, tūī, and kākā. Berries are an important winter food source for forest birds. Seeds dispersed by birds.
Habitat
Lowland and montane forests throughout New Zealand. The dominant emergent giant of temperate rainforest, often towering over broadleaf canopy on ridges and damp terrace lands alike.
Range
Found throughout North and South Islands, Stewart Island, and Chatham Islands in lowland and montane forests. Most common in West Coast, Fiordland, central North Island, and Stewart Island.
Endemism
Endemic
Main Threats
Habitat loss is the primary threat – old-growth stands heavily logged for prized decorative timber. Also threatened by possum browsing on seedlings and by land clearance.
Population
Not Threatened, though old-growth stands heavily logged for prized decorative timber. Still common in native forests, but 50-metre giants are now mostly found in protected reserves and wetter West Coast valleys.
Conservation Status
Not Threatened
The architectural elegance of the New Zealand bush. Rimu reaches heights of over 50 metres and lives for more than 1,000 years, but its most striking feature is its weeping, pendulous foliage. When juvenile, it looks like a soft, vibrant green fountain, with long, slender branchlets draping toward forest floor in a delicate, cascading pattern. This weeping design is a clever survival strategy – thin, needle-like leaves optimised to shed heavy, constant rainfall of New Zealand rainforest, preventing branches from becoming waterlogged or snapping under weight of a Southern storm. As Rimu matures, it undergoes a dramatic transformation into a pillar of sky. Lower branches drop away, leaving a massive, straight trunk that can reach over two metres in diameter. Bark is dark brown and flaky, peeling off in large, shaggy scales that give trunk a rugged, textured appearance. This rough bark provides a perfect vertical garden for epiphytes, orchids, and ferns to take root, meaning an ancient Rimu is rarely just one tree – it is a towering high-rise apartment for hundreds of other species. Underneath this shaggy exterior lies the Red Pine heartwood – a rich, deep-grained timber that became gold standard for New Zealand furniture and house framing during colonial era due to its incredible strength and shimmering, figured patterns. Biologically, Rimu is a slow-burn reproducer. Dioecious – separate male and female trees. It does not produce seeds every year. Instead, it waits for a mast year – every three to five years – to release a massive pulse of pollen and fruit. Seeds carried on a fleshy, bright red receptacle that looks like a tiny berry. These are a critical high-energy food source for kākāpō and kererū, who in turn act as Rimu primary gardeners by spreading seeds throughout forest. Without these birds, Rimu would struggle to colonise new ground. The tree that gives the New Zealand bush its drip – the constant, rhythmic sound of water falling from its long, needle-thin leaves into ferns below. To stand beneath an ancient Rimu is to experience the quiet, misty heart of the prehistoric wild, a tree that has mastered the art of being both a massive titan and a graceful, weeping willow of the Southern Hemisphere.
