Site description The proposed La Soufrière National Park occupies the majority of the northern quarter of the island. It is the largest IBA and encompasses St. Vincent’s most northerly and youngest volcano. The volcano’s 1-mile (1.6-km) wide summit crater, whose north-east rim is cut by a crater formed in 1812, lies on the south-west margin of the 1.4-mile (2.2-km) wide Somma crater, which is breached widely to the south-west as a result of slope failure (Smithsonian Institution, 2000). Historically, La Soufrière first erupted in 1718, followed by another in 1812. Both produced major explosions. In 1902, another eruption devastated much of the northern end of the island. That eruption coincided with that of Mount Pelée on Martinique. ‘A lava dome was emplaced in the summit crater in 1971 during a strictly effusive eruption, forming an island in a lake that filled the crater prior to an eruption in 1979. The lake was then largely ejected during a series of explosive eruptions, and the dome was replaced with another’ (Smithsonian Institution, 2000) (Plate 20). Its activity is monitored locally by the Seismic Unit within the Ministry of Agriculture, and in association with the University of the West Indies in Trinidad. The active La Soufrière is one of St. Vincent’s main tourist attractions. Volcanic eruptions have devastating effects on the surrounding ecosystem, which contains a mixture of secondary rainforest and volcanic pioneer vegetation. It is an area of unique ecological significance because it has the largest area of succession forest in St. Vincent (Ivor Jackson and Associates, 2004).
