help New Caledonia FAQ
Why does New Caledonia have so many unique plant species?
New Caledonia was once part of the ancient supercontinent Gondwana and has been geographically isolated for millions of years. Its highly specific ultramafic soils, which are rich in heavy metals but poor in nutrients, forced local flora to adapt in ways found nowhere else on Earth.
What is the most famous native conifer in New Caledonia?
The island is famous for Araucaria columnaris, also known as the Cook pine, which dominates many of the archipelago's landscapes. The region actually hosts an incredibly high diversity of Araucariaceae conifers compared to the rest of the world.
Are there venomous snakes or dangerous wildlife in New Caledonia?
New Caledonia is famously devoid of highly dangerous terrestrial animals, with no native land snakes posing a significant threat. However, the surrounding waters are home to saltwater crocodiles and various sea snakes, so caution is advised near the coast.
What kind of soil do I need to grow New Caledonian plants at home?
Plants from this region typically require specialized, heavily drained soil that mimics their native ultramafic substrates, often requiring low phosphorus levels. Gardeners usually mix pumice, sand, and specific mineral aggregates to prevent root rot in these highly endemic species.
