Liana Pandemic Threatens Tropical Rainforests: Visible from Space
2025-05-11
A new study reveals a dramatic surge in lianas in tropical rainforests, jeopardizing carbon storage and biodiversity. Lianas, which spread rapidly and outcompete trees for resources, are increasing by 10-24% per decade. This is linked to rising atmospheric CO2 levels, as lianas benefit disproportionately from increased CO2. The resulting tree mortality and hampered forest regeneration lead to a 95% reduction in carbon storage. Surprisingly, their unique leaf properties make lianas detectable from space, opening new avenues for monitoring their spread. Researchers urge a focus on climate change mitigation and caution against intervention until the lianas' full ecological role is understood.
