In an effort to bolster the local fish population, the Forest Department is launching a project called Vriksha Samridhi, Matsya Samridhi, which involves planting selected varieties of trees along the lakeside at the Periyar Tiger Reserve (PTR).
The Vriksha Samridhi, Matsya Samridhi Project:
The Forest Department’s project aims to plant six specific varieties of trees along the lakeside at Periyar Tiger Reserve. Notable among these are njaval (Syzygium cumini) and pattathali (Actinodaphne malabarica). These tree species produce fruits that serve as an essential food source for fish species residing in the lake, particularly the Mahaseer (Kuyil) fish. By ensuring adequate food security for the fish, the project aims to increase local fish production within the lake.
Targeted Tributaries and Planting Strategy:
As part of the project, the Forest Department has identified seven tributaries, including the Periyar River, Mullathode, and Maruthalithode, which flow into the lake. Planting the chosen tree species along these tributaries will provide a natural supply of fallen fruits for the fish population. Moreover, the trees will be planted above the maximum water level (MWL) of the lake, ensuring their stability and longevity.
Combatting Threats to Local Fish Wealth:
In addition to the tree planting initiative, the Forest Department is taking measures to safeguard the local fish wealth from threats posed by invasive species. A concerted effort is underway to eradicate the African catfish, tilapia, and goldfish that were introduced to Periyar Lake from outside sources. These non-native species pose a significant threat to the survival of indigenous fish species.
The Importance of Periyar Tiger Reserve:
Periyar Tiger Reserve, located in the Western Ghats of Kerala, holds immense ecological significance. Declared a Tiger Reserve in 1978, it derives its name from the Periyar River, which originates deep within the reserve. The reserve is also home to two major rivers, Pamba and Periyar, which play a vital role in shaping its ecosystem. Periyar Tiger Reserve is not only renowned for its rich biodiversity but also for being a sanctuary for various tribal communities, including the Mannans and the Palians.
Implications of the Project:
- Enhanced Fish Production: By providing a sustainable and natural food source through the planting of specific tree species, the project aims to boost fish production in Periyar Lake. This increase will not only benefit local communities dependent on fishing but also contribute to the conservation of indigenous fish species.
- Ecological Balance: The planting of trees along the lakeside will contribute to the overall ecological balance of Periyar Tiger Reserve. These trees will provide shade, improve soil health, and attract a variety of other wildlife, creating a thriving ecosystem within the reserve.
- Community Engagement: The project presents an opportunity for local communities, forest department officials, and conservationists to collaborate in enhancing the ecological health of Periyar Tiger Reserve. Such engagement fosters a sense of ownership and responsibility among stakeholders, promoting the sustainable management of the reserve’s resources.
- Conservation of Indigenous Species: By eradicating invasive species, particularly the African catfish, the project aims to protect and preserve the native fish species of Periyar Lake. This conservation effort is crucial for maintaining the overall biodiversity and ecological integrity of the lake and its surrounding areas.
