Pacific Science 56(3): 299-315. https://doi.org/10.1353/psc.2002.0030. Due to the geographic isolation of the Hawaiian Islands, close to 25% of Hawaii's reef fishes and red algae species are endemic. This leaves Hawaiian coral reefs particularly vulnerable to alien invasions due to their valuable role as a biodiversity resource. Invasive algae can pose a serious threat to coral reefs by spreading and growing rapidly, smothering or outcompeting corals and other organisms. This can significantly alter the structure and function of the reef ecosystem. Four species of alien red algae have become invasive in Hawaii: prickly seaweed (Acanthophora spicifera), hookweed (Hypnea musciformis), smothering seaweed (Kappaphycus spp.), and gorilla ogo (Gracilaria salicornia). This raster data layer represents the presence of alien and invasive algal species within 1 km of an observation. Invasive algae data originated from monitoring surveys in the University of Hawaii at Manoa (UH) Fisheries Ecology Research Laboratory (FERL) Hawaii Fish and Benthic Biological Synthesis Database (2000-2013), which is synthesized from NOAA, State of Hawaii Division of Aquatic Resources (DAR), Coral Reef Assessment and Monitoring Program (CRAMP), and The Nature Conservancy (TNC), as well as invasive algae surveys conducted across the state in 2002 by Dr. Jennifer Smith (Smith et al., 2002). These data should be considered presence only. Areas with no presence may be due to lack of survey data, surveys that did not identify algae to the species level, or observed absence. Point data for transects with observed presence of any invasive algae were assigned a value of 1 and converted to raster with 500-m pixel size. To account for uncertainty in geographic position and the fragmentation and spread of algae, the Ocean Tipping Points (OTP) project estimated presence within a 1-km radius of observed invasive algae presence. A Focal Statistics tool was run to calculate the maximum value within a 1-km radius of each pixel with the assumption that if an invasive algae was observed in one location it is likely present in at least the surrounding 1 km of reef area. Final raster values of 1 represent areas within 1 km of positive invasive algae observations while values of 0 represent the remaining area. The geographic extent of the data layer is from the shoreline of the Main Hawaiian Islands extending 5 km offshore and 1 km inshore. 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 (OTP) project (http://oceantippingpoints.org). Ocean tipping points occur when shifts 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, including critical coral reef management and policies to protect ecosystem services produced by coral reefs. The goal of the Ocean Tipping Points Hawaii case study was to gather, process, and map spatial information on environmental and human-based drivers of coral reef ecosystem conditions.
