38% of the World’s Tree Species Are Facing Extinction

38% of the World’s Tree Species Are Facing Extinction. The alarming reality of our planet’s biodiversity crisis has taken center stage at the UN biodiversity summit COP 16 in Cali, Colombia, where new findings have revealed that over a third of the world’s tree species are now at risk of extinction.

The staggering 38% of tree species threatened globally underscores the urgent need for conservation efforts. Trees play an irreplaceable role in the ecosystem, not only supporting wildlife but also acting as critical absorbers of carbon dioxide, essential for mitigating climate change.

Yet, deforestation, land clearing, logging, and the increasing spread of pests and diseases are driving tree species towards the brink of extinction. This blog examines the causes behind this crisis, its implications for global biodiversity, and the concerted actions required to safeguard these vital ecosystems.

The Scope of the Crisis: How Trees Are Being Pushed to the Edge

In an unprecedented assessment conducted by over 1,000 scientists from the Botanic Gardens Conservation International (BGCI) and the International Union for Conservation of Nature (IUCN), data shows that tree species worldwide are facing unparalleled threats.

The study, which fed into the latest extinction red list update, paints a grim picture: there are now more tree species in danger than threatened species of birds, mammals, reptiles, and amphibians combined.

Emily Beech of BGCI, one of the leading voices in the study, highlighted the scale of the problem, revealing that deforestation, agricultural expansion, and unsustainable logging practices have pushed tree species in 192 countries into crisis.

Key tree species that provide habitats, food, and resources for countless other life forms are now at high risk. For instance, magnolias, oaks, maples, and ebonies—all iconic species with immense ecological and economic value—are among the most endangered.

As forests are cleared and fragmented, these species are losing their habitats. Meanwhile, the increased prevalence of pests and diseases, exacerbated by climate change, further endangers these trees, particularly in temperate regions.

The loss of these trees would have severe cascading effects on the ecosystems they support, affecting countless other species and posing a direct threat to global biodiversity.

The Ripple Effect: Biodiversity and Ecosystem Collapse

The extinction of tree species doesn’t just signify the loss of individual species; it represents a blow to the entire ecosystem. Trees are keystone species, meaning their presence is crucial for the survival of a wide range of other plants, animals, and microorganisms.

Conservation researcher Steven Bachman from the Royal Botanic Gardens, Kew, emphasized that losing trees would lead to a domino effect on the many organisms that rely on them for habitat, sustenance, and shelter. Birds, mammals, insects, fungi, and even other plants are interconnected with the presence of diverse tree species.

For example, forests are essential for migratory birds, providing stop-off points and habitats along their migration routes. However, as forests shrink, birds like the grey plover, dunlin, turnstone, and curlew sandpiper are seeing their populations decline.

Similarly, the European hedgehog, a much-loved mammal, has experienced significant habitat loss, moving it closer to extinction. As human activities like land development and farming continue to encroach on natural habitats, these animals are being deprived of the environments they depend on.

This demonstrates how the decline of tree species reverberates throughout the food chain, affecting a variety of species and causing a disruption in biodiversity.

Trees also play an invaluable role in the carbon cycle, acting as natural carbon sinks that absorb significant amounts of CO₂ from the atmosphere. Without these trees, CO₂ levels in the atmosphere would rise, exacerbating the impacts of climate change.

The destruction of forests, therefore, not only endangers specific species but also accelerates climate change, posing further threats to ecosystems and human populations globally. The consequences of these intertwined crises of climate change and biodiversity loss are far-reaching, affecting not just the environment but also human health, food security, and economies.

Urgent Conservation Efforts: A Global Call to Action

The findings revealed at COP 16 have underscored the critical need for global leaders to take decisive actions to reverse these biodiversity declines. World leaders gathered in Cali, Colombia, to review progress on a crucial pledge: protecting 30% of the world’s lands, seas, and oceans by 2030.

However, the path to achieving this target faces numerous obstacles, including securing sufficient funding, developing enforceable protections for ecosystems, and strengthening national biodiversity conservation plans.

The summit has highlighted the gap between ambitious goals and the resources needed to fulfill them, with finance for preserving biodiversity still an unresolved issue.

Organizations like the BGCI, IUCN, and the Royal Botanic Gardens, Kew, are making significant efforts to mitigate the crisis. Conservationists are collecting seeds, cultivating endangered tree species in arboretums, and working on ground-level conservation actions to restore and preserve threatened tree populations.

These initiatives aim to safeguard genetic diversity, ensure resilience to climate change, and support habitat restoration. Yet, these efforts require substantial funding, public support, and global cooperation.

Local actions also play a critical role in conservation. Communities, governments, and NGOs around the world are working to promote sustainable forestry practices, curb illegal logging, and establish protected areas for endangered species.

Programs aimed at restoring deforested areas, particularly in biodiversity hotspots, are essential to reversing habitat loss. Additionally, increased awareness and education on the importance of biodiversity can mobilize public support, encouraging more people to participate in conservation initiatives.

As COP 16 continues, the need for international collaboration is increasingly apparent. Protecting the world’s remaining forests and implementing sustainable land-use practices is a collective responsibility that requires commitment from all levels—local, national, and global.

By prioritizing the conservation of tree species and the ecosystems they support, humanity has the chance to address biodiversity loss and mitigate the effects of climate change, ensuring a more resilient planet for future generations.
