A recent study conducted by Thevara SH College at HMT Estate in Kalamassery has highlighted the rich biodiversity of this urban green enclave, one of the last remaining in Kochi. Spanning 80 acres, HMT Estate is a sanctuary for a diverse array of flora and fauna, making it a crucial area for conservation amidst the city’s rapid urbanisation.
The study identified 136 plant species across 45 families and 63 bird species, including migratory birds and those listed as near-threatened or vulnerable. This underscores the urgent need for conservation efforts to protect this biodiversity hotspot. The estate’s mixed forest and wetland ecosystem harbours several species listed on the IUCN Red List, including endangered plants like Syzgium caryophyllatum (kattu njaval) and vulnerable species such as Hopea ponga (Kambakam). Assistant professor of the Botany department, who led the study, remarked, “The biodiversity survey identified 13 migratory bird species in the estate, highlighting the importance of this green cover. However, we found that waste from the nearby town is being burned here, posing a significant threat to the ecosystem. Additionally, anti-social elements are setting fires to the woods.”
The pristine nature of HMT Estate plays a crucial role in maintaining the local groundwater table. “The intact groundwater table helps retain water in the two or three wells in the adjacent areas, which are vital for the local community. Tanker lorries frequently draw water from these wells,” the assistant professor added. The findings of this study call for immediate action from authorities to address the threats faced by HMT Estate. The conservation of this green enclave is not only vital for preserving its biodiversity but also for maintaining the ecological balance and water resources of the region. As urbanisation continues to encroach upon natural habitats, the importance of protecting areas like HMT Estate cannot be overstated. Conservation efforts must be prioritised to safeguard the rich biodiversity and ensure that such green spaces remain a refuge for both wildlife and the local community. The study by Thevara SH College serves as a wake-up call, urging prompt and effective measures to conserve one of Kochi’s last urban green enclaves.
