Bothrops insularis is known only from one location: a small island off southeastern Brazil (total area 43 ha). The species' highly restricted range and continuing decline in habitat quality, as a result of removal of vegetation by people from the Brazilian Navy who keep the lighthouse, qualify it for the Critically Endangered category.
|Previously published Red List assessments:||
|Range Description:||Bothrops insularis is known only from Queimada Grande Island, off the coast of São Paulo, southeastern Brazil (Campbell and Lamar 1989).|
Native:Brazil (São Paulo)

|Current Population Trend:||Stable|
|Habitat and Ecology:||The species occurs in lowland rainforest areas.|
|Major Threat(s):||The main threat to the species is the destruction of habitat. Large areas of the island have been destroyed through repeated burning. The continuation of such activities threaten the survival of the species.|
