The long-term ecological implications of yellow boy remain unknown. Relatively large amounts of litter are laid-down, thus transforming the habitat substantially. (Lambdon, P. & Darlow, A. (2008) Botanical Survey of Ascension Island and St. Helena 2008. RSPB);
It is an early-succession pioneer and may therefore help to stabilize almost bare ground. (Lambdon, P. & Darlow, A. (2008) Botanical Survey of Ascension Island and St. Helena 2008. RSPB);
