The Rainforest Gardeners: Protecting the "Noah's Ark for Plants" in Kerala
In the lush landscapes of northern Kerala, South Western India, a dedicated team of twenty to forty local women is performing a quiet revolution. Known as the rainforest gardeners, these women are the primary caretakers of the Gurukula Botanical Sanctuary, a vital refuge for endangered flora. Through their tireless work, they are preserving the biological heritage of the Western Ghats, one plant at a time.
The sanctuary serves as a living library of biodiversity. By seeking out, preserving, and cultivating species that are under threat from urban sprawl, climate change, and deforestation, these women act as guardians for what many call the "Noah's Ark for Plants."

A Sanctuary Born from Conservation
The Gurukula Botanical Sanctuary was founded in 1981 by Wolfgang Dieter Theuerkauf, a self-taught German conservationist. Located near the Periya reserve forest, the 32-hectare private, collectively owned sanctuary was designed to combat the rapid loss of native species. The site is a complex ecosystem consisting of greenhouses, nurseries, open beds, a rainforest, and community living spaces.
A central feature of the sanctuary is its two-acre botanical garden, which is open to the public and serves as a hub for educational programs. The overarching mission is to restore habitats and conserve approximately 2,000 plant species. Before his passing in 2014, Theuerkauf mentored a group of local women to care for rare native plants—including orchids, ferns, and succulents—that he had rescued from land being cleared for development.
Today, the sanctuary is a critical stronghold for biodiversity. While the Western Ghats mountain range is a recognized UNESCO World Heritage Site, it faces massive threats from human activity. Currently, the sanctuary provides a refuge for 40% of the plant species found in the Western Ghats region. Since 2006, the community project has received support from Rainforest Concern.
From Local Caretakers to Scientific Experts
What makes the story of the Gurukula gardeners truly remarkable is their journey from local laborers to recognized experts in ecology (the study of how organisms interact with their environment). Most of these women left school by the age of 15 or 16 and entered the sanctuary without formal training in botany (the scientific study of plants) or conservation biology.
Through years of meticulous observation and experimentation with growing conditions, they have mastered the art of plant cultivation. Their expertise is now being recognized by the global scientific community. Many have discovered new plant species, co-authored articles in scientific journals, and presented their findings at botanical seminars.
Leading Figures in the Movement
- Sheena Mol: A senior gardener who joined the community at the age of 15, marking her very first job.
- Laly Joseph: Originally training as an X-ray technician, Joseph joined the sanctuary as a volunteer 35 years ago. She now searches for rare plants under threat and restores them within the sanctuary. Her contributions were so significant that she was included in the "2025 World Everyday Heroes" section of The Guardian Weekly in December 2025.
- Suprabha Seshan: Originally from Delhi, Seshan joined as a volunteer intern in 1991. She has since become a renowned, prize-winning conservationist involved in reforestation and education projects.

Restoration and Rewilding Methods
The work of the gardeners extends beyond the sanctuary's borders. They actively work to restore degraded lands, such as adjacent tea and coffee plantations that the sanctuary has acquired over time. Their approach to rewilding—the process of returning an area to its natural state—is characterized by low-intervention methods.
Rather than heavy industrial landscaping, the team uses natural processes such as selective cutting, clearing, planting, and tree dispersal. This allows the forest to regenerate in a way that is organic and sustainable. To perform this demanding work, the women often work long hours and wear protective boots to guard against snakes and leeches.

Frequently Asked Questions
What is the main goal of the Gurukula Botanical Sanctuary?
The sanctuary aims to restore natural habitats and conserve approximately 2,000 plant species, acting as a "Noah's Ark" for the endangered flora of the Western Ghats.
Do the gardeners have scientific degrees?
Most of the women do not have formal qualifications in botany or conservation biology; however, through years of hands-on experience, many have become recognized ecology experts and scientific co-authors.
How do the gardeners restore the forest?
They use low-intervention methods such as tree dispersal, planting, and selective clearing to allow the forest to undergo a natural rewilding process.
Why is the Western Ghats area at risk?
Despite being a UNESCO World Heritage Site, the area's biodiversity is threatened by a growing population, urban sprawl, deforestation, and the effects of climate change.
