This layer was developed as part of a geospatial database of key anthropogenic pressures to coastal waters of the Main Hawaiian Islands for the Ocean Tipping Points project (http://oceantippingpoints.org/). Ocean tipping points occur when incremental changes in human use or environmental conditions result in large, and sometimes abrupt, impacts to marine ecosystems. The ability to predict and understand ocean tipping points can enhance ecosystem management. The goal of the Hawaii case study of the Ocean Tipping Points project was to gather, process and map spatial data on environmental and anthropogenic drivers of coral reef ecosystem states. Understanding direct anthropogenic drivers is critical for coral reef management and implementing policies to protect ecosystem services generated by coral reefs.

All Analysis performed in ArcGIS 10.1
Point data for transects with observed presence of any invasive reef fish was assigned a value of 1 and converted to raster with 500 m pixel size using the point to raster tool.
Next Focal Statistics was run to calculate the maximum value within a 2 km radius of each pixel with the assumption that if an invasive species was observed in one location it is likely present/established in at least the surrounding 2 km of reef area. The resulting map portrays a 500 m raster of invasive fish within 2 km of an observed presence.
