Bengaluru, India – Dr. K. Sankara Rao, a Visiting Professor and Distinguished Fellow at the Centre for Ecological Sciences (CES), Indian Institute of Science (IISc), is not merely a botanist; he is a fervent advocate for the arboreal world, a scholar whose life’s work is dedicated to understanding and preserving India’s rich tree diversity. His office at IISc, a sanctuary overflowing with botanical texts and his own meticulously crafted field guides, is a testament to his profound connection with trees, which he affectionately calls his "natural abode." This deep-seated passion, cultivated since childhood spent amidst leafy canopies, has now culminated in the creation of a groundbreaking digital resource aimed at revolutionizing India’s approach to afforestation.
The Arboreal Architect: A Lifelong Dedication to Trees
Dr. Rao’s desk, a vibrant landscape of botanical literature, is a testament to his unwavering commitment. Titles like Pradip Krishen’s "Jungle Trees of Central India" and "Trees of Delhi," alongside publications from the Botanical Survey of India and his own seminal two-volume field guide, "Trees of Bangalore," paint a vivid picture of his scholarly pursuits. This extensive collection underscores his deep expertise and his desire to make this knowledge accessible.
"Trees are nature’s exceptional creations," Dr. Rao explains, his voice resonating with genuine admiration. He emphasizes their crucial role in sustaining life, highlighting that they are the foundation for "80% of terrestrial biodiversity." From the birds and butterflies that grace their branches to the lichens, mosses, and small mammals that find shelter within their ecosystems, trees are veritable hubs of life. Furthermore, they create microclimates that allow understory vegetation, such as shrubs and herbs, to thrive, contributing to a more robust and resilient environment.
A Growing Concern: The Perils of Misguided Afforestation
Despite his profound love for trees, Dr. Rao harbors a deep-seated concern about the current trajectory of afforestation efforts in India. The alarming loss of green cover across the nation is a constant source of distress. However, his unease is particularly amplified by the "afforestation" practices being implemented by policymakers, which he believes are fundamentally flawed and detrimental to tropical biodiversity.
"Tree planting schemes have lately become carbon-centric, particularly single-species plantations, which are further threatening tropical biodiversity," he states with a sense of urgency. Dr. Rao points out a critical paradox: while a vast reservoir of native arboreal species exists, the common practice favors the widespread planting of only a handful of indigenous species. This homogenization, he argues, leads to monocultures that, while seemingly increasing green cover, fail to replicate the intricate ecological balance of natural forests.
The Misconception of "Afforestation": When Woods Are Not Forests
The current emphasis on planting large numbers of a single species, such as nutmeg, clove, eucalyptus, conocarpus, or areca nut, is a misnomer for true afforestation, according to Dr. Rao. Such practices, he contends, actively endanger biodiversity rather than nurturing it. He draws a stark distinction, quoting a poignant observation: "all woods are not forests." This highlights the qualitative difference between a collection of trees and a complex, self-sustaining forest ecosystem.
Dr. Rao passionately advocates for a paradigm shift in afforestation strategies. He believes that a thorough understanding of tree species, with a particular emphasis on native varieties, must form the bedrock of any reforestation initiative. "Where we plant a particular species matters," he asserts. "Planting has to be done where a given species once grew." This principle of ecological restoration, rooted in understanding historical vegetation patterns, is crucial for re-establishing healthy and resilient ecosystems.
India Trees and Vegetation Types: A Digital Beacon for Restoration
Fueled by his extensive knowledge and profound concerns, Dr. Rao and his dedicated team have developed a pioneering digital resource: "India Trees and Vegetation Types." This ambitious project aims to consolidate the country’s vast arboreal knowledge onto a single, accessible digital platform. "The website…provides scientific and vernacular names, herbarium specimen scans and field photographs, morphological descriptions, and information on the habitat, geographical distribution, and threat status of the species," Dr. Rao elaborates.
The ultimate goal of this digital repository is multifaceted. It seeks to empower anyone with an interest in trees by providing comprehensive information. More importantly, it aims to serve as a practical blueprint for reforestation and restoration efforts, ensuring that planting is conducted on a "scientific basis…with hope of rebuilding our native forest." This digital initiative represents a significant step towards informed and effective ecological management.
A Journey of Discovery: From Biochemistry to Ecological Sciences
The genesis of "India Trees and Vegetation Types" is a story of serendipity and a lifelong passion reignited. While Dr. Rao’s interest in plants was always present, his professional career began in the Biochemistry Department at IISc. It was only after retiring from biochemistry that he found himself, quite unexpectedly, at the Centre for Ecological Sciences (CES) in 2006.
"One day, I was just passing by the CES department when I ran into Raman Sukumar, then its Chair," he recalls. Professor Sukumar, recognizing Dr. Rao’s latent passion and academic rigor, invited him to join CES and entrusted him with the department’s herbarium, with the encouraging directive to "do what I liked with it." This pivotal moment marked a turning point, allowing Dr. Rao to fully immerse himself in his true calling.
Embracing the Digital Frontier: From Herbarium to Virtual Flora
Initially, Dr. Rao recognized that a collection of dried specimens in the herbarium, while scientifically valuable, had limited appeal to the general public or even to practitioners not deeply versed in botany. This realization spurred him to embrace the digital age. "The idea to make a virtual herbarium came to my mind," he shares. This visionary approach has already led to the creation of several other online databases, including "Digital Flora of Karnataka," "Digital Flora of Eastern Ghats," "Flora of Peninsular India," and "India Flora Online."
His methodology for creating these comprehensive databases involved more than just digitizing existing records. Dr. Rao actively revisited and explored numerous locations where the plants had been originally collected, as documented in the herbarium. "I referred to books and literature to better understand the vegetation types that we had and have been having for some time," he explains. "It is understanding the past history that will tell us what to do in the present." This commitment to historical ecological understanding is a cornerstone of his work.
A Landmark Achievement: Digitizing India’s Arboreal Heritage
The "India Trees and Vegetation Types" website, which meticulously documents approximately 4,380 tree species, was formally launched on June 20th of this year. However, the groundwork for this monumental project stretches back nearly two decades, a testament to Dr. Rao’s perseverance and dedication.
Dr. Rao proudly highlights the significance of this endeavor, stating, "This is the first time something like this has been done in over 120 years." He draws a parallel to Dietrich Brandis’s seminal work, "Indian Trees," published in 1906, which was a comprehensive compilation of trees during the British era. "So much has changed since then, and the change has been drastic," Dr. Rao observes, underscoring the urgent need for an updated and accessible repository of information.
He further emphasizes the unparalleled advantage of a digital platform: "having this information in the digital realm, rather than in a book, simply makes it more accessible." In an era where digital access is paramount, his sentiment resonates: "today, who looks at a book?" he remarks with a touch of wry humor.
Supporting Data and Expert Endorsements
The "India Trees and Vegetation Types" database is more than just an online catalog; it is a meticulously curated resource designed to inform and guide conservation efforts. The inclusion of scientific and vernacular names aids in universal understanding, while herbarium specimen scans and field photographs provide visual verification and context. Detailed morphological descriptions, coupled with information on habitat, geographical distribution, and threat status, offer a holistic view of each species. This comprehensive data empowers researchers, policymakers, and the public alike to make informed decisions regarding tree conservation and restoration.
The scientific community has recognized the immense value of Dr. Rao’s work. Experts in ecology and conservation biology have lauded the initiative for its potential to address critical gaps in our understanding of India’s tree diversity and to promote scientifically sound afforestation practices. The platform’s emphasis on native species and historical ecological patterns directly confronts the limitations of current, often ecologically simplistic, tree-planting programs.
