la central area near Cordla grove fied-footed Booby on an egg with three fresh 
ends of stems (TribuiusT 'in the nest. In the same area 2.5 - 4 in, of litter 
is found on the ground' (dried leaves from Tribulug stems). As on Bast Island, 
Pearl and Hermes, the disturbed sites have a'very""thick covering of Trlbulus 
to the exclusion of almost all other secies. Disruption seems -to glvetKis 
specie* a competitive advantage. Here on Howland the central area is devoid 
of other species over large areas. These is a tendency for Trlbulus to assume 
dcminance in area* of heavy bird nesting (ie both north and sSitK^portions of 
the island),
