Rediscovery of the Indus Dolphin in India
- The Indus dolphin (Platanista gangetica minor), once thought to be extinct in India since 1930, has made a surprising return!
- These fascinating aquatic mammals, primarily found in the Indus River system of Pakistan, were recently spotted in the Beas River near the Harike wetland area.
- This sighting is significant, especially since the species is listed as endangered in the Red Data Book of the International Union for the Conservation of Nature (IUCN).
A Remarkable Discovery
- On the morning of December 14, 2007, Basanta Rajkumar, an Indian Forest Service officer responsible for the area, spotted these dolphins while touring the region in a motorboat.
- Following this exciting discovery, a team of freshwater dolphin conservationists from the World Wildlife Fund (WWF) India was called in to conduct a survey.
- They observed a family of about six dolphins at two different locations along a 25-km stretch of the Beas River, confirming the claims made by state forest officials.
Confirmation from Experts
- The find has been validated by an authority on freshwater dolphins from the Wildlife Institute of India in Dehradun, which specializes in managing endangered species.
- This remarkable discovery in 2007, a year designated by the United Nations as Dolphin Year, was celebrated as a notable event.
- Interestingly, about 140 km downstream from the Harike Barrage, in Pakistan, Indus dolphins are frequently observed, highlighting the unique habitat of this endangered species.
Conservation Efforts for the Gharial
- The gharial (Gavialis gangeticus), a unique species of crocodile, was once abundant in the Indus River system.
- However, due to significant declines in its population, it is now classified as critically endangered on the International Union for Conservation of Nature’s (IUCN) Red List of Endangered Species.
A New Initiative in Punjab
- In a bid to revive this remarkable species, the Punjab Government is taking proactive measures. They plan to release 10 gharials into the Harike Wetlands.
- This initiative aims not only to bolster the gharial population but also to attract more tourists to the region.
Challenges Facing the Harike Wetlands
- The Harike Wetlands, in existence since 1953, have experienced significant transformations over the years due to various factors. Here are some of the key issues impacting this vital ecosystem:
1. Encroachments and Agricultural Practices
- Encroachments on the wetland habitat for intensive agriculture have led to the influx of agricultural chemicals into the area. This practice, alongside controversial land use, has severely affected the wetland’s health.
2. Water Utilization
- The excessive use of surface and groundwater for irrigation has put immense pressure on the wetland, altering its natural flow patterns.
3. Pollution from Waste Discharge
- Untreated waste from towns, villages, and industrial activities is routinely discharged into the rivers that feed the wetland.
- This has resulted in significant pollution, with estimates indicating that about 700 million liters per day of polluted water is released.
- Consequently, there has been extensive growth of water hyacinth, a problematic invasive species, covering approximately 80% of the open water surface and enclosing 33 islands within the wetland.
4. Soil Erosion and Siltation
- Deforestation in the lower Shivalik hills, which form the wetland’s catchment area, has led to soil erosion and siltation, further impacting the ecosystem’s stability.
5. Illegal Activities
- Despite the protections provided under the Wildlife (Protection) Act, illegal fishing and poaching continue to threaten the area’s biodiversity.
6. Grazing Pressure
- Indiscriminate grazing in the catchment areas has caused further damage to the delicate wetland ecology.
Remote Sensing Findings
- A remote sensing study, combined with analyses of rainfall, water discharge, and groundwater levels, revealed that the flow patterns in the wetland have diminished.
- Over a 13-year study period, the size of the wetland area has decreased by approximately 30%.
Restoration Efforts
- The Harike Wetlands have faced significant degradation, prompting a variety of restoration measures initiated by numerous organizations, including central and state government agencies and local Indian Army Units. These collaborative efforts aim to rehabilitate this vital ecosystem through several key actions.
Harike Wetland Conservation Mission
- In 1998, the Chief Minister of Punjab established the Harike Wetland Conservation Mission with the following objectives:
- a) Master Plan Development: To create a comprehensive master plan for the integrated conservation and development of the Harike Wetland.
- b) Project Implementation: To carry out specific projects and programs focused on conserving the ecosystem of the Harike region.
- c) Regulation and Monitoring: To oversee and assess all development activities affecting the Harike Wetland ecosystem.
- d) Evaluation of Government Proposals: To review and evaluate all plans and proposals from government departments that impact the future of Harike.
Combatting Water Hyacinth
- The issue of water hyacinth, an invasive plant species choking the wetland, was addressed in 2000 through a collaborative initiative between the Indian Army (Western Command, Vajra Corps) and the Chief Minister.
- Under the pilot project named “Sahyog,” the Army implemented innovative mechanical systems for weed removal.
An Army General reported on their progress, stating:
“Through various innovative methods, we created dynamic booms and winches. After the operation, we strategically placed static and dynamic booms in Harike Lake to prevent the further spread of water hyacinth. After six months of dedicated work by our team, we successfully opened four channels that had been choked with silt over the years. Additionally, we planted 750 saplings of two-year-old plants on the islands for birds to nest and roost in the future.”
Management Plan by Punjab State Council for Science and Technology
The Punjab State Council for Science and Technology developed a management plan that includes the following actions:
- Opening sluice gates during monsoon seasons to regulate water flow.
- Monitoring water quality during migration periods to ensure a healthy ecosystem.
- Fencing selected areas to protect them from encroachment.
- Afforestation of the catchment area to enhance biodiversity.
- Surveying, mapping, and notification of wetland boundaries and resources.
- Soil conservation initiatives to prevent erosion and degradation.
- Education and public awareness campaigns to engage the community in conservation efforts.
Celebration of World Wetlands Day at Harike
- On February 2, 2003, World Wetlands Day was celebrated at Harike, emphasizing the crucial message: “No Wetlands, No Water.”
- This event not only highlighted the importance of wetlands but also coincided with the International Year of Freshwater.
Significance of the Celebration
- The day served as a reminder of the vital role wetlands play in maintaining healthy ecosystems and providing essential resources such as clean water.
- Celebrating this occasion at Harike helped raise awareness among local communities and stakeholders about the significance of wetland conservation and sustainable water management.
