Trees for Migratory Birds

Puducherry, India

Available for Adoption: 7,500 Trees


The plantation project of 7500 native saplings to be implemented scattered in 3 regions of - Oussudu Lake Bird Sanctuary, fringes of the Bahour Lake and Oorani community land in Puducherry, India.

The Oussudu Lake Bird Sanctuary is an old man-made lake situated near the Puducherry town and has been recognized as one of the important wetlands of Asia by the International Union for Conservation of Nature and Natural Resources (IUCN) and it is the most important freshwater lake in the Puducherry region. The wetland acts as the single largest catchment of fresh water in Puducherry.

The Bahour Lake is a freshwater wetland and second largest lake in Puducherry state. The lake is recognized as one of the Important Bird Areas (IBA) of Puducherry for the number of birds sighted (about 25,000 waterfowl) and for having more than 1% of the biogeographic population of several species of waterfowl including Eurasian Wigeon Anas penelope and Little Grebe Tachybaptus ruficollis.

Oorani Community land is situated at the catchment of coastal lagoon wetlands - the Kaliveli, where farming is still a primary activity among the locals. The region possesses one of the largest wetlands in peninsular India and is considered a wetland of international importance proposed by the International Union for the Conservation of Nature and Natural Resources (IUCN). The region is home to many migratory birds as well as resident birds for their roosting and breeding habitats. Among others, the region is home to near threatened bird species such as Grey Pelican, Open-billed stork and Painted Stork.


To improve wetland habitats with the planting of ecologically valued native tree species
To incentivize locals with increased forest-based activities with thorough involvement in project implementation
To restore the endemic and endangered flora-fauna improving the wildlife habitats with native tree plantation.

Why Trees

Between 2000 and 2012, 2.3 million square kilometres of forests around the world were cut down (The Nature Conservancy, 2015). Deforestation is often cited as one of the major causes of the enhanced greenhouse effect and a significant contributor to global warming (Fearnside, Philip M.; Laurance, William F, 2004. "Tropical Deforestation and Greenhouse-Gas Emissions"). The loss of forest cover influences the climate and contributes to a loss of biodiversity. The economic activity is adversely affected by siltation, flooding, soil degradation and reduced timber supplies which in turn, threatens the livelihood of people. The strategic tree planting helps to address escalating climate and geographical disruption by sequestering atmospheric carbon, replenish groundwater and rivers, protect biodiversity and improve their habitat enhancing local livelihoods. Native tree plantation represents one of the simplest and best solutions to the myriad changing climate issues of our present day planet.

Kaliveli is a seasonal wetland, with a gradient from freshwater to brackish water. The region is home to several rare and endangered floral, faunal and mostly avifaunal species. The wetland is considered of both national and international importance by the International Union for Conservation of Nature (IUCN).  Increased encroachment from an expansion of agricultural fields, depletion of forests from changing land use pattern, loss of wildlife habitat and fragmentation, rapid soil and increased deforestation are major conservation concerns for the region.

Trees for migratory birds

Oussudu lake attracts over 20,000 birds of 40 rare species from all parts of the world every year, and the season is from August to November. Greater Flamingo from Great Rann of Kutch is one of the primary guests of this migratory season. The different species of birds including Spot Billed Pelicans, Painted Stork, Spoon Billed Ducks, Whistling Ducks, and Black Headed Ibis, are regular visitors to the place. Birds use the patches of greenery to rest and refuel in the middle of their journey between winter and breeding sites. Within migration, land birds spend up to 90% of their time resting and regaining energy at stopover sites, making habitat a key component for their migration to a particular destination.

According to a study done by Swiss Federal Institute for Forest, Snow and Landscape Research with the Institute of Ecology and Evolution at the University of Bern, 13 species of birds will be found when no trees are present, whereas 20 species are in place when tree cover increases to 45 per cent. The researchers of this study determined that ‘the positive effect of trees outweighs the negative effect of sealed area and buildings. Therefore, increasing tree cover is a more promising and efficient measure to enhance bird species richness and diversity.

Flora and Fauna

Endemic plant species like Barringtonia acutangula and Acacia nilotica to be planted at the surroundings of Oussudu Lake Bird Sanctuary and the Bahour Lake. Mixed ecologically valued native species like Albizia amara, Cassia fistula, Syzigium cumini, Tamarindus indica, etc. are selected for plantation at the Oorani Community lands.

Expected Output

Plantation of trees will create workdays to the villagers, including tribal women leading to an increase in awareness and participation in conservation efforts by the locals.  Trees will promote indigenous tree species which will not only enhance green cover but also aid conservation of biodiversity by providing them with natural habitat and additional sources of food addressing degradation and habitat fragmentation; mainly for the endemic and migratory bird species. There will be increased ecosystem services to the communities in the form of fruit, fodder and non-timber forest produces on the maturity of the planted trees. 7,500 trees are expected to offset about 1,50,000 of kgs carbon annually on their maturity. Several studies have shown that the planting of trees ensures that the rain droplets sink into the soil controlling surface runoff thus increasing the groundwater table.
