This document provides information on a land use mapping project for Pigeon Island in Sri Lanka. It includes:
- Background on Pigeon Island being declared a sanctuary in 1963 and national park in 2003.
- Gaps in existing data and studies that need to be addressed.
- Methods that will be used including satellite images, software, and data analysis procedures.
- Expected outputs including land cover maps at different administrative levels, socioeconomic data, fisheries data, protected areas, and administrative boundaries.
The project aims to fulfill existing data gaps on coastal habitats, land use, and more to provide information to agencies involved in decision making for the Pigeon Island Special Management Area. A variety of data sources

*Identify the impact from the land area due to the agricultural
practices and other industrial establishment along the coastal line
in quantitatively.
* Identify the extent of live coral areas and demarcate those areas in
order to set management objectives and formulated management
plan to ensure long term management of the coral reef ecosystem.
*Identify extent of mangrove in the study area and in individual
lagoon and estuaries.

*Provide adequate qualitative and quantitative data and information to
relevant agencies for Pigeon Island Special Management Area(PISMA).
*Fulfill data gaps in existing studies and assessment already conducted in
the area.
*Prepare bench mark of Existing coastal habitat, Geographical extent,
Mangrove, Forest, Coastal vegetation, very specifically Coral distribution
and other land cover and land use data etc.
*Share data and information among the key agencies involved in decision
making process at local level.

Anthropogenic threats to the pigeon island can be
summarized as follows;
• Sand mining along the beach: (Sampalthivu and
Kappalthurai )
• Pollution mainly occurred by visitors to the area of
Welgamvehera, Pigeon Island, Nilaveli beach,
Girihanduseya.
• Damage to the coral reef ecosystem by visitors’ boat:
• Walking and snorkeling on the coral reef
• Fisheries activities:
Coral and Algae competing (EML, 2013)
Natural threats
•Excess algal growth
•Invasive alien species: Acanthster planci (Crown of Thorne or
COT)

51. 51
• Development of a visitor management plan to reduce the human
pressure to the ecosystem and avoid overcrowded the area
• Construction of floating resting places in the reef area to avoid
coral damage by bathing and walking on the reef area.
• Development of visitor facilities including toilets, cafeterias,
sales centre for education material and merchandise. The visitor
centre should be created awareness among the visitor about the
ecological importance of the Pigeon island National Park and
the rules and regulation that are applicable to the visitors.
• Manage the Solid waste generated within the park
• Introducing a Zonal plan
Some of the key management activities suggested to management of natural
resources in the study area by previous studies and Pigeon Island Management
Plan are as follows.

1. Public use zone
2. Habitat protection zone
