Vegetation recovery in the highlands

Tremendous ground hunting effort was invested on Santiago Island between
December 2001 and June 2004. The northern side of the island shows the high
numbers of goats that have been eradicated. Added to this are the results obtained doing
mustering and corrals which were not included in the final block results.
Despite the fact that the spatial dimension has always been taken into account for work
planning, early data were not gathered using a methodology that could be integrated in
the GIS and thus are not on the map; a lesson learnt throughout the project.
Not on map:
• 22,732 goats
• 21,221 mustering hours
