Description

Survey and Mapping of Rapid Ohia Death in Hawaii Survey and Mapping of Rapid Ohia Death in Hawaii Mapping of ohia forests on Hawaii and Maui Islands using a unique technology carried today only onboard the Carnegie Airborne Observatory or CAO (https://cao.carnegiescience.edu) called laser-guided imaging spectroscopy (LGIS), measures the fine chemical properties of forest canopies in 3-D to detect area affected by Rapid Ohia Death (ROD). No other operational LGIS capabilities exist in the U.S. civil or military sectors. LGIS is an approach invented and operationalized by scientists at the Carnegie Institution for the purpose of rapidly advancing ecosystem mapping in support of management, conservation and resource policy actions (Asner et al. 2012). Remote sensing has been identified as a critically important contributor to forthcoming management strategies intending to control the spread of ROD. Without remote sensing that details the condition of each tree among all trees in the forest, field crews will not know where to apply tactical control measures to contain the disease. The remote sensing needs to be detailed from a biological standpoint, rather than from the traditional remote sensing standpoint of broad thematic maps of forest cover often reported by mapping scientists. The imagery is 3D to provide an understanding of the size and structure of the trees affected, while the spectral data provide a clear detection of which trees have died , and which trees are in jeopardy of dying. It is also straightforward to detect and map live, healthy trees. The Big Island was previously mapped twice using this technology and if a clear picture is to be painted we need to compare the same types of images over time. Adding Maui to the survey area allows us to establish a baseline for ohia forests there before the disease spreads to that island. We will map as much of the Big Island and Maui as is possible, and we will produce maps of the potential locations of Rapid Ohia Death (ROD). We will provide the maps in GIS-compatible format the DOFAW and its partnering agencies.
