Follow the Science

At TNC, science is at the heart of everything we do. It guides every decision, shapes every strategy, and drives every solution. As we confront the crises of climate change and biodiversity loss, our commitment to world-class science has never been more important. Today, we’re focused on turning bold ideas into real-world impact, scaling solutions that drive lasting, systemic change for people and nature.

Innovating for People and the Planet: The Scientific History of TNC

Science is the backbone of The Nature Conservancy’s mission to conserve the lands and waters on which all life depends. It provides the evidence base we need to set priorities, design effective strategies, and measure our impact. Science empowers us to address complex environmental challenges with solutions that are grounded in data, scalable across geographies, and rooted in the needs of local people and communities. 

From our origins in the Ecological Society of America to our evolution into a global conservation leader, science has always defined who we are. Today, more than 1,000 science staff across all 50 U.S. states and more than 80 countries and territories are advancing TNC’s mission through interdisciplinary research and collaboration. With expertise covering more than 60 disciplines, our scientists work hand-in-hand with partners and communities to create solutions for nature, climate, and people that are locally grounded and globally scalable.

At TNC, science is inclusive, collaborative, and focused on impact. Our teams integrate cutting-edge technologies like remote sensing, artificial intelligence, and bioacoustics with Indigenous and local knowledge to develop solutions that work in the real world. Whether advancing climate adaptation, marine spatial planning, sustainable agriculture, or natural climate solutions like agroforestry and reforestation, TNC science is designed to be used—informing decisions, guiding policy, and driving change at scale.

At The Nature Conservancy, science is more than a tool or a discovery. It’s how we turn knowledge into impact, all with the goal of creating a thriving future for life on Earth.

Where Science Meets Impact

At TNC, science isn’t just a tool, it’s a bridge to a better future for biodiversity, climate and communities.

How Restoration Is Helping Cape Town Save Water

A nature-based approach is helping Cape Town strengthen water security by removing thirsty invasive trees from critical watersheds and restoring native fynbos ecosystems. By combining large-scale restoration with innovative financing, the Greater Cape Town Water Fund is increasing water flows, supporting biodiversity recovery and building resilience to future droughts at a fraction of the cost of traditional water infrastructure.

Reconnecting Rivers for Nature and Communities

Removing obsolete dams is helping restore Europe's rivers while delivering benefits for people and nature. By reconnecting fragmented waterways, river restoration projects can improve water quality, revive fish populations, strengthen climate resilience and support local economies through recreation and fisheries. A growing movement across Europe is demonstrating how strategic barrier removal can recover freshwater ecosystems and the services they provide.

Protecting the Amazon's Forgotten Fishes

A first-of-its-kind assessment highlights the Amazon Basin's extraordinary freshwater fish diversity and the opportunity to protect it before large-scale ecological decline occurs. Combining scientific research with Indigenous and local knowledge, the report shows how healthy, connected rivers support biodiversity, food security, livelihoods and cultural identities. Accelerated, basin-wide conservation could help safeguard one of the world's most important freshwater ecosystems for future generations.

Planting Climate-Ready Forests in Minnesota

A record-setting tree planting effort is helping strengthen the future of northern Minnesota's forests. By planting 3.2 million seedlings across fire- and disease-affected landscapes, The Nature Conservancy and its partners are increasing forest diversity, improving wildlife habitat and supporting long-term resilience to wildfire, pests and climate change. The science-based approach aims to help forests continue providing clean water, recreation and economic benefits for generations to come.

What Enables Landowners to Restore Nature

New research highlights how native forest restoration in Aotearoa New Zealand can be expanded by better aligning conservation programs with landowner priorities. The study found that farmers are motivated by benefits such as biodiversity, water quality and stewardship for future generations but often need financial incentives and practical support to participate at scale. Thoughtfully designed restoration programs could help accelerate revegetation while delivering benefits for nature, communities and climate resilience.
