This layer depicts the status, or degree of disturbance, to plant communities on the main Hawaiian Islands. To more precisely identify areas where native species may presently be found, a map was generated that considers the following three categories of habitat quality: High, areas dominated by native vegetation; Medium, areas dominated by nonnative vegetation; and Low, highly modified landscapes. The primary source for mapping these three categories is the HIGAP land-cover classification (Gon, 2006). The High category includes all HIGAP land-cover classes that are considered to be either native dominated or mixed native and nonnative in order to represent those areas that have substantial native-species composition....

This dataset provides information on the current status and various other habitat and descriptive attributes of the native coastal vegetation for seven of the main Hawaiian Islands (i.e., does not include Ni`ihau).

This layer depicts projected abundance of native and non-native plant species in the main Hawaiian Islands with high levels of uncertainty removed in post-processing. To estimate native and invasive species abundance in baseline climate conditions, a map was generated that considered abundance as percent cover and used high coefficient of variation values as a mask. The primary sources for post-processing the uncertainty masks are the Hawaiian Islands plant species abundance modeled means and standard deviation values (Wong et al., in preparation). These maps cover the entire landscape (including urban and agricultural areas), and therefore they can be applied in a variety of ways. Maps can be utilized to evaluate...

This report describes the design, field methodology, and first year results of a vegetation survey and long-term monitoring program to assess the status and document changes in the dominant native plant communities relative to alien species management efforts within the Kipuka Alala section of the Pohakuloa Training Area (PTA) on the island of Hawai`i. Kipuka Alala is recognized by the Army to be an important habitat that contains a number of unique plant communities as well as populations of several listed or rare plant species. Additionally, Kipuka Alala has been identified as a potential site for the reintroduction of the Palila (Loxioides bailleui), an endangered species of Hawaiian Honeycreeper bird that was...

In 1976-1981, the U.S. Fish and Wildlife Service conducted systematic surveys of forest birds and plant communities on all of the main Hawaiian Islands as part of the Hawaii Forest Bird Surveys (HFBS; Scott, J.M., S. Mountainspring, F.L. Ramsey, and C.B. Kepler. 1986. Forest bird communities of the Hawaiian Islands: their dynamics, ecology, and conservation. Studies in Avian Biology 9:1-431). Results of this monumental effort have guided conservation efforts and provided the basis for many plant and bird recovery plans and land acquisition decisions in Hawaii during the past two decades. Unfortunately, these estimates and range maps are now seriously outdated, hindering modern conservation decision-making efforts...

This feature class contains vegetation polygons for the upland areas on the island of Hawaii (Big Island). This map was orignally plotted on 1:24000-scale map sheets, using aerial photos taken in the years 1976-1977. Thus this map represents a snapshot of the vegetation at this time. The original mapping project was part of the the Hawaii Forest Bird Survey, and consequently only bird habitat areas of interest (495,454 ha or 47% of the island) were mapped. This dataset has the most detailed level of mapping, including information on canopy cover, canopy height, dominant tree species composition, species association type, dominant understory composition, and other information pertaining to the map unit.

This map represents the distribution of seven moisture zones for the main Hawaiian Islands. The maps were produced as part of a species range modeling effort for the Hawaiian flora. Details on methodology and related products can be found in: Price, J. P., J. D. Jacobi, S. M. Gon, III, D. Matsuwaki, L. Mehrhoff, W. L. Wagner, M. Lucas, and B. Rowe. 2012, Mapping plant species ranges in the Hawaiian Islands-Developing a methodology and associated GIS layers. U.S. Geological Survey Open File Report OFR 2012-1192, Reston, VA.
