World Wildlife Day 2026: Simple ways to support conservation

Every year on March 3, the world observes World Wildlife Day, a day to remind us that wild animals and plants quietly sustain life as we know it.

Established by the United Nations, the date marks the anniversary of the signing of the Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES) in 1973. That agreement was created to ensure international trade does not push species toward extinction.

This year’s theme is “Medicinal and Aromatic Plants: Conserving Health, Heritage and Livelihoods”. Medicinal and aromatic plant cultivation and harvest practices are a source of resources for many households around the world, who rely on wild plants, algae and fungi for their food and income.

It can be tempting to think of wildlife conservation as something distant — rainforests far away, endangered animals we’ll never see. But World Wildlife Day invites us to look closer at the herbs in our tea cabinet, the essential oils in our diffuser, the wood in our furniture to understand the ecosystems behind everyday products.

Why focusing on medicinal and aromatic plants matters

This year’s World Wildlife Day focus shows that conservation ideas are expanding into more significant discussions of plant diversity.

More than 70,000 plant species are used globally for medicinal, cultural, and aromatic purposes. They support healthcare systems, sustain rural and Indigenous livelihoods, fuel global wellness industries, and help maintain ecosystem balance. Many modern medicines are plant-derived, and traditional healing systems often have an element of reliance on wild-harvested species.

At the same time, demand for herbal supplements, essential oils, and natural remedies has surged. As plant-based living becomes more mainstream, so does pressure on wild populations.

The primary threats are straightforward but serious: overharvesting, habitat destruction, climate change, and illegal or poorly regulated trade. Plants that once regenerated naturally are now being harvested faster than they can recover.

Examples of threatened regions and why they’re impacted

Some of the most uniquely biodiverse regions on Earth are also the most vulnerable.

Tropical rainforests in the Amazon, the Congo Basin, and Southeast Asia are under pressure from cattle ranching, soy production, palm oil plantations, mining, and infrastructure expansion. These forests contain thousands of medicinal plant species — many not yet studied scientifically. When forest ecosystems are cleared, there is a risk that these medicinal plant species are impacted as well.

High-altitude ecosystems, including Himalayan and alpine regions, are also at risk. Valuable medicinal herbs harvested for global markets are increasingly over-collected, while rising temperatures shrink already fragile habitats.

Medicinal plants under pressure

Several examples of well-known medicinal and aromatic plants under pressure include:

• Sandalwood – Harvested for its fragrant heartwood oil used in aromatherapy, perfumes, and skincare. Sandalwood trees are semi-parasitic, meaning they rely on host plants in their ecosystem to thrive. They take decades to produce commercially valuable heartwood, and various factors have caused decline in natural populations in parts of Asia and Australia.
• Frankincense (Boswellia trees) – Valued for anti-inflammatory properties and long-standing cultural and spiritual uses. These trees grow in arid, rocky environments and regenerate slowly. Over-tapping (excessive resin extraction), grazing pressure, and climate stress reduce seed viability and natural regeneration rates.
• Medicinal orchids – These plants have been used in traditional medicine systems as vitality tonics. Many orchids depend on highly specific environmental conditions therefore habitat disturbance can quickly collapse populations.

When harvesting outpaces regeneration, or ecosystems are fragmented, recovery can move slowly.

Simple ways to mark World Wildlife Day

Thoughtful, small actions can meaningfully reduce pressure on vulnerable ecosystems.

One small action is to pay attention to what we consume: are our herbal teas, supplements, and essential oils transparently sourced? Could we choose certified or locally grown options? Reducing consumption of products linked to deforestation and unsustainable land use is equally impactful.

Supporting organizations that protect habitats and wildlife — even modestly — helps fund long-term conservation work. Sharing informed information using #WorldWildlifeDay can also help amplify the message.

And perhaps most practically, consider growing a few medicinal herbs yourself! Even a small windowsill garden reduces commercial demand and reconnects you with the source of what you use.

The bigger perspective

The health of our environment — including plants and wildlife— underpins medicine, clean water, climate regulation, and cultural identity. World Wildlife Day is a reminder that conservation is not abstract but woven into daily life.

Sometimes global change begins with policy shifts and international agreements and sometimes it begins with something as small as noticing products around our homes.
