This species inhabits some of the more exposed sites, such as bare rock slopes and steep cinder banks. It is found at altitudes greater than 600 metres above sea level (2).Top
Sporobolus caespitosus is classified as Critically Endangered (CR) on the IUCN Red List (1).Top
It is thought that Sporobolus caespitosus was previously more abundant than it is today. It may be suffering from competition with introduced species, such as the grasses Sporobolus africanus, Melinis minutiflora and Paspalum conjungatum (3).Top
Ascension Conservation is involved with monitoring the population of this rare grass and will be in a position to assess the effects of competition (3).Top
