Flora and Fauna of Indawgyi Lake

Wildlife Sanctuary and Conservation Status

Indawgyi Lake is part of the Indawgyi Lake Wildlife Sanctuary, which was established in 1999 to preserve its rich natural resources. The sanctuary spans 780 km² (300 sq mi) and includes a variety of habitats, such as wetlands, grasslands, and forests. It is home to a wide range of species, both terrestrial and aquatic, many of which are endangered.

Fish and Aquatic Life

The lake hosts over 65 species of fish, which contribute to the biodiversity of the region. Although none of these species are endemic to the lake, some were initially thought to be unique before being discovered in other parts of Myanmar.

• The lake’s water quality and fish population support the livelihoods of local fishermen who rely on the lake for their primary source of income.

Birds and Birdwatching

Indawgyi Lake is an Important Bird Area (IBA) due to its significance as a stopover for migratory birds. The lake and its surrounding wetlands serve as vital habitats for both migratory and resident bird species, particularly during the winter months.

Notable Bird Species

• Endangered Species: The lake is home to several endangered bird species, including greylag geese, purple swamphen, and oriental darter. These species are most prominent from November to February.
• Vultures: Indawgyi Lake is one of the key habitats for critically endangered vulture species. Both the White-rumped Vulture (Gyps bengalensis) and the Slender-billed Vulture (Gyps tenuirostris) are resident in the area and breed here year-round.
• Migratory Birds: As part of the Asian-Australasian Flyway, the lake serves as an important stopover for migratory birds, particularly in the winter season. Thousands of migratory waterfowl, including ducks, waders, and shorebirds, are observed annually.

Indawgyi Lake is considered one of the top birdwatching destinations in Myanmar, attracting both local and international ornithologists and eco-tourists.

Mammals and Endangered Species

The sanctuary is home to a variety of mammalian species, including some that are endangered and threatened. Notable species include:

• Hog Deer (Axis porcinus): Discovered in the Indawgyi region during 2011 biodiversity surveys, these deer are listed as vulnerable due to hunting pressures and habitat destruction. They inhabit the northern part of the lake’s grasslands and are crucial to the region’s biodiversity.
• Primates and Small Carnivores: Other wildlife species found in the sanctuary include various primates and small carnivores that play important roles in the ecosystem.

Wetland Habitat and Invertebrates

In addition to the fish and birds, the wetlands surrounding the lake support a range of aquatic plants, invertebrates, and other wildlife. These wetlands are crucial for maintaining the ecological balance and provide essential feeding grounds for birds and other animals.

Geological Formation of Indawgyi Lake

Tectonic Origins

Indawgyi Lake is a sag pond that formed due to tectonic movements associated with the Sagaing Fault, a major active strike-slip fault that runs through Myanmar. The movement of the earth’s crust along this fault created a pull-apart basin—a geological feature where land sinks due to faulting. This process is similar to the formation of the Salton Trough in California.

The oral history of the area suggests that the lake may have been created by a massive earthquake that caused a valley to flood, submerging a village and its inhabitants. However, the subsidence caused by tectonic activity is generally accepted as the cause of the lake’s formation, creating a unique geological feature.

Conservation and Protection Efforts

Historical Conservation

Conservation efforts around Indawgyi Lake date back to colonial times, when the British established forest reserves for watershed protection. However, modern conservation challenges began to mount after the 1990s, when an influx of migrants from other parts of Myanmar led to increased agricultural development, forest clearing, and overfishing. As a result, the lake’s environment began to degrade.

Key Conservation Milestones

Indawgyi Lake has been designated with several important environmental recognitions due to its global ecological significance:

• Wildlife Sanctuary: Established in 1999 to protect the biodiversity of the region.
• ASEAN Heritage Park: Recognized in 2004 for its outstanding biodiversity.
• Ramsar Wetland: Indawgyi Lake was designated a Ramsar Wetland Site in 2016, acknowledging its importance as a wetland of international importance.
• UNESCO Biosphere Reserve: In 2017, the lake became part of the UNESCO Biosphere Reserve, reflecting its value in sustainable development and conservation.

Current Conservation Strategy

The current strategy for protecting Indawgyi Lake is comprehensive and includes multiple approaches that emphasize sustainable practices, community involvement, and scientific research. Some of the key areas of focus include:

1. Sustainable Fisheries: Promoting responsible fishing practices to prevent overfishing and preserve aquatic biodiversity.
2. Community-Based Ecotourism: Encouraging sustainable tourism practices that benefit both the environment and local communities.
3. Waste Management and Sanitation: Establishing proper waste disposal systems to prevent pollution of the lake and surrounding ecosystems.
4. Environmental Education: Raising awareness among local communities about the importance of conservation and providing training on sustainable practices.

The collaboration of local NGOs, Fauna & Flora International (FFI), the Myanmar Forest Department, and Friends of Wildlife is vital to the continued success of these conservation efforts.

Ecotourism and Community Engagement

Ecotourism Opportunities

Indawgyi Lake offers significant opportunities for ecotourism, which contributes to the region’s economic development while promoting environmental sustainability. Some key attractions for visitors include:

• Birdwatching: Visitors can spot rare and endangered bird species, particularly migratory birds during the winter months. Birdwatching tours are one of the primary activities for eco-tourists.
