brings the total number of identified species to 607. Tuvalu's exclusive economic zone (EEZ) covers an oceanic area of approximately 900,000 km2. Tuvalu is a party to the Convention on Biological Diversity. The predominant vegetation type on the islands of Tuvalu is the cultivated coconut woodland, which covers 43% of the land. The native broadleaf forest is limited to 4.1% of the vegetation types. Tuvalu contains the Western Polynesian tropical moist forests terrestrial ecoregion. Environmental pressures The eastern shoreline of Funafuti Lagoon on Fongafale was modified during World War II when the airfield (now Funafuti International Airport) was constructed. The coral base of the atoll was used as fill to create the runway. The resulting borrow pits impacted the fresh-water aquifer. In the low-lying areas of Funafuti, the sea water can be seen bubbling up through the porous coral rock to form pools with each high tide. In 2014, the Tuvalu Borrow Pits Remediation (BPR) project was approved so that 10 borrow pits would be filled with sand from the lagoon, leaving Tafua Pond, which is a natural pond. The New Zealand Government funded the BPR project. The project was carried out in 2015, with 365,000 sqm of sand being dredged from the lagoon to fill the holes and improve living conditions on the island. This project increased the usable land space on Fongafale by eight per cent. During World War II, several piers were also constructed on Fongafale in the Funafuti Lagoon; beach areas were filled and deep-water access channels were excavated. These alterations to the reef and shoreline resulted in changes to wave patterns, with less sand accumulating to form the beaches, compared to former times; the shoreline is now exposed to wave action. Several attempts to stabilise the shoreline have not achieved the desired effect. The reefs at Funafuti suffered damage during the El Niño events that occurred between 1998 and 2001, with an average of 70% of the Staghorn (Acropora spp.) corals becoming bleached as a consequence of the increase in ocean temperatures. A reef restoration project has investigated reef restoration techniques; and researchers from Japan have investigated rebuilding the coral reefs through the introduction of foraminifera. The project of the Japan International Cooperation Agency is designed to increase the resilience of the Tuvalu coast against sea level rise, through ecosystem rehabilitation and regeneration and through support for sand production. The rising population has resulted in
