This file contains the raw data collected as part of a vegetation monitoring study that was conducted to assess the changes in plant species frequency inside and outside a fenced exclosure, constructed to eliminate browsing and grazing by feral goats, from 2009-2014 in the US Geological Survey's Kawela research site on the island of Molokai, Hawaii.

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....

List of all plant species found in, or adjacent to, plots K1 or K2 during all the sampling periods. Species recorded at least once during the vegetation transect surveys are marked with “Yes”. The taxonomy follows Wagner and others (2005).
· Anticipating potential shifts in plant communities has been a major challenge in climate-change ecology. In the State of Hawaii, where conservation efforts tend to be habitat focused, the lack of projections of vegetation shifts under future climate is a major knowledge gap for developing management actions for climate-change mitigation and adaptation.· As a first approximation, we have modeled potential shifts of terrestrial vegetation across the Hawaiian landscape between now and the end of this century. Our approach relies on modeling the relation between current climate and the distribution of broad climatically determined moisture zones (MZs; for example, wet, mesic, and dry areas) that form the...

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...

This layer depicts the status, or degree of disturbance, to plant communities on the main Hawaiian Islands. Several layers were uset to create this version (v 3.4). The original HabQual layer was developed by Jon Price and Jim Jacobi based on the mapped land cover units from the Hawaii GAP analysis program (Gon et al. 2006). This map was revised by combining data on land use and the “Bare” category from the NOAA C-CAP 2005 map (NOAA National Ocean Service Coastal Services Center 2012), and adding road corridors to the heavily disturbed category based on the Tiger Roads layer (United States Census Bureau 2014). Additionally, corrections were made to this version of the map by visually inspecting previously mapped...

Hawaiian forest birds are imperiled, with fewer than half the original > 40 species remaining extant. Recent studies document ongoing rapid population decline and project complete climate-based range losses for the critically endangered Kaua’i endemics ‘akeke’e (Loxops caeruleirostris) and ‘akikiki (Oreomystis bairdi) by end-of-century due to projected warming. Climate change facilitates the upward expansion of avian malaria into native high elevation forests where disease was historically absent. While intensified conservation efforts attempt to safeguard these species and their habitats, the magnitude of potential loss and the urgency of this situation require all conservation options to be seriously considered....

This data release contains two files: 1) the raw data collected as part of a vegetation monitoring study that was conducted to assess the changes in plant species frequency inside and outside a fenced exclosure, constructed to eliminate browsing and grazing by feral goats, from 2009-2014 in the US Geological Survey's Kawela research site on the island of Molokai, Hawaii. 2) A list of species that were recorded during the vegetation monitoring or species that were found in the general area but not recorded during monitoring.

While there have been many maps produced that depict vegetation for the state of Hawai‘i only a few of these display land cover for all of the main Hawaiian Islands, and most of those that were created before the year 2000 have very generalized units or are somewhat inaccurate as a result of more recent land use changes or due to poor resolution (both spatial and spectral) in the imagery that was used to produce the map. Some of the more detailed and accurate maps include the Hawai‘i GAP Analysis (HI-GAP) Land Cover map (Gon et al. 2006), the NOAA C-CAP Land Cover map (NOAA National Ocean Service Coastal Services Center 2012), and the more recently released Hawai‘i LANDFIRE EVT Land Cover map (U.S. Geological Survey...
This data layer identifies location and boundaries for 100 randomly located plots used to assess the accuracy of the Hakalau Forest Unit (HFU) map area for the vegetation map of the Hakalau Forest National Wildlife Refuge Hakalau Forest Unit and adjacent lands.

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.

One of the impacts of global climate change for the Hawaiian Islands is a projected increase in sea level of about one meter by the year 2100. This change will impact both biological and cultural resources located along the coastline. Few intact native coastal and lowland plant communities remain in Hawai’i. Many of those that remain contain listed endangered species and provide important habitat for other species such as seabirds, shorebirds, and native invertebrates. Where upslope habitats are available, some coastal plant communities may be able to migrate in response to sea level rise. However, in sites that have no upslope opportunities due to habitat modification by human development, the species and communities...

These two raster data layers depict the land cover and degree of human disturbance to plant communities on the seven main Hawaiian Islands, and were developed as part of a comprehensive USGS assessment of carbon sequestration potential by natural ecosystems in the State of Hawaii.
