Following a sloth through a rainforest sounds like the slowest field job imaginable. In reality, it can mean mud, lost radio signals, long hours staring into leaves and years of patient data collection. That persistence is now helping shape real conservation action.
Dr Rebecca Cliffe, founder and executive director of The Sloth Conservation Foundation, has been named among the applicants for the 2027 Indianapolis Prize Emerging Conservationist Award. The recognition is exciting, but the more useful story is what sits behind it: long-term research that connects individual sloths to bigger decisions about habitat, roads, wildlife law and trade.
Sloths are difficult to study precisely because they are quiet, cryptic and often high in the canopy. A brief sighting can tell a researcher where one animal was at one moment. Following the same animals over months and years can reveal how they actually use a changing landscape.
A nomination rooted in fieldwork
The Indianapolis Zoo's applicant announcement describes the Emerging Conservationist Award as a biennial recognition for conservationists under 40 whose work shows strong promise for protecting threatened wildlife. A review committee will select three finalists, with the winner due to be announced in September 2027.
Cliffe is one of a broad international group of applicants working on animals from pangolins and fishing cats to elephants and rare birds. Her listing highlights pioneering long-term studies of wild sloths and says that this work has helped guide research, policy and practice.
It is important to keep the wording accurate. This is a nomination, not a win, and the selection process is still ahead. Yet being included also draws attention to a kind of conservation that can be easy to overlook because its results accumulate slowly.
Why long-term sloth research matters
A sloth's life cannot be understood from a handful of dramatic encounters. Researchers need repeated observations to see which trees are used, how far an animal travels, when it rests, how it responds to weather and where its route becomes dangerous.
The UCLA Institute of the Environment and Sustainability profile says Cliffe began working in Costa Rica at 18 and pioneered the first long-term field studies of wild sloths. It describes the resulting body of information as a major dataset on sloth ecology.
That continuity matters because rainforest conditions are not fixed. A familiar route can be broken when one tree is removed. A road, power line or new building can turn an ordinary journey into a hazardous crossing. Data collected before and after those changes helps show which problems are occasional and which are repeated features of the landscape.
Following one animal can reveal a community problem
Tracking an individual sloth may look like very small-scale science. Its value grows when the same methods are used across many animals and places.
If several tracked sloths repeatedly descend to the ground at the same canopy gap, the issue may not be clumsiness or bad luck. It may reveal a missing connection that could be repaired with native planting or a carefully placed canopy bridge. If animals cluster around private gardens, conservation may depend on working with local landowners rather than protecting only distant reserves.
This is where observation becomes practical. A tracking point is not automatically a solution, but it helps teams ask better questions: Which route needs reconnecting? Which trees should be planted? Where should a bridge be monitored? Which road project needs stronger wildlife safeguards?
From science to connected habitat
Long-term data is most useful when it leaves the spreadsheet. Cliffe's work through The Sloth Conservation Foundation combines research with habitat connectivity, education, advocacy and community participation.
The UCLA profile points to Connected Gardens, a community-led project that links small actions on private land into a wider network of canopy connections. This approach recognises that an urban or semi-urban sloth does not experience the landscape as a neat division between protected forest and everywhere else.
A garden tree, roadside branch or gap between properties can all affect whether an animal remains above ground. Helping residents understand those connections turns conservation from an abstract idea into visible, local choices.
Evidence can also influence rules
The official award announcement says Cliffe's work has informed national wildlife regulations and contributed to new legal protections for sloths. Her current work also addresses the international trade in wild-caught animals.
Science does not make policy by itself. It provides evidence that campaigners, communities and decision-makers can use. Long-running studies are especially valuable because they can show patterns rather than relying on a single rescue story or viral image.
That does not make individual animals unimportant. Quite the opposite. Each tracked sloth contributes a piece of evidence about what the species needs in a real landscape. The challenge is to translate those pieces into safer infrastructure, better habitat and rules that prevent harm before a rescue becomes necessary.
Conservation is patient work
The Sloth Conservation Foundation's nomination announcement traces a path from research to habitat protection, wildlife connectivity, education and advocacy. It also notes earlier recognition, including a Future For Nature Award and an honorary doctorate from Swansea University.
Awards can give conservation work welcome visibility, but they are not the work itself. The real achievement is the patient chain from finding an animal, collecting reliable observations and recognising a pattern to testing a practical response with the people who share that landscape.
Sloths may be famous for moving slowly, yet studying them shows how quickly a habitat can become difficult to navigate. Long-term research gives conservationists something better than a guess. It gives them a record of where sloths go, what interrupts them and which changes might genuinely help.
That is why following a sloth matters. The animal may travel only a short distance during a field shift, but the evidence gathered along the way can reach gardens, roads, national policy and international wildlife protection.
