In the tropics, ample freshwater is the primary resource supporting thriving human and ecological communities. In the Pacific Islands, many watersheds are threatened by climate change, urban encroachment, and invasion by water-demanding exotic plant species like strawberry guava (SG). To maintain an adequate freshwater supply, adaptive management strategies are needed to address these concerns while confronting operational barriers to implementation. We developed a prototype watershed decision support tool (WDST) that incorporated: (i) distributed hydrology modeling to quantify effects of climate change and SG invasion on freshwater yield; (ii) a decision support tool that linked potential changes in yield with...

The objective of this experimental research is to determine if genetic enrichment may enhance survival, growth, and adaptation of important native Hawaiian montane plant species to changing precipitation patterns by relocating conspecifics to more favorable climate regimes at higher elevation. We will collect the seeds of montane plants from low and high eevation sources, conduct outplanting trials in common locations along an elevation gradient, and monitor growth, survival, and vigor over a two_year period to evaluate a potential restoration strategy for mountain parklands of Mauna Kea, on the island of Hawaii.

To anticipate how weather is likely to change as a result of increasing concentrations of greenhouse gases (such as carbon dioxide) in the atmosphere, geophysical and meteorological scientists examined the results of climate models on the fine scale climate patterns of Hawai’i to understand what future climate will look like. Researchers analyzed the relationship of past rainfall with global processes in order to predict future rainfall patterns. They found that the decades-long decrease in rainfall seen in arid and semiarid regions of Hawai‘i during the rainy season (November-April) is likely to continue. The model results show that all of the Hawaiian Islands get drier overall in the 21st century. Of all the islands,...

The Virginia Department of Conservation and Recreation – Natural Heritage Program (DCRDNH) and the Florida Natural Areas Inventory (FNAI) at Florida State University (collectively, Project Partners) were funded by the South Atlantic Landscape Conservation Cooperative (SALCC) in April 2015 to develop ten species distribution models (SDM) of priority at-risk andrange-restricted species (Ambystoma cingulatum, Echinacea laevigata, Heterodon simus, Lindera melissifolia, Lythrum curtissii, Notophthalmus perstriatus, Phemeranthus piedmontanus, Rhus michauxii, and Schwalbea americana) for the purposes of incorporating the models and supporting information on the conservation and management needs of the species into the...
This project involved developing a new design for the South Atlantic LCC website (including development of new code and graphics/images as needed) and designing a factsheet template, an online newsletter template, a powerpoint template, and small info cards based on the modern website redesign. The project initially specified the Ning 3.0 platform, which changed to WordPress when Ning stopped supporting upgrades to Version 3.0.
The objectives of this open pine and woodland rapid ecological assessment are to provide information about (1) how much and where the pine-dominated landscapes in the GCPO meet the criteria for open pine habitat as defined in the Integrated Science Agenda (ISA), (2) how much more such habitat is needed, and (3) where opportunities exist to manage for these conditions (through thinning, burning, reforestation, enhancement, etc.). The ISA defines the desired ecological state for open pine as “woodlands and savannas that are floristically rich and comprised mostly of site-appropriate pine with low basal area, open canopies, and dense herbaceous understories in large interconnected blocks.”

This data represents an assessment of forest patch size used in the ecological assessment of upland hardwood systems by the GCPO LCC. We used a combination of remote sensing products including 2011 National Land Cover Database (NLCD) forest classes and the 2011 MAV forest classification layer produced by the Lower Mississippi Valley Joint Venture to delineate patches of all forest types in the GCPO LCC. We used NLCD as the primary data source when assessing forests outside the GCPO LCC MAV subgeography, and the LMVJV forest classification as the primary data source for forest assessment within the MAV. NLCD was developed using 2011 Landsat TM imagery, with forest classes including only areas with trees exceeding...

This pilot project will assist the South Atlantic Landscape Conservation Cooperative (SALCC) identify issues dealing with the integration of natural and cultural resource sustainability and recommend optimal strategies for solving impacts associated with landscape stressors like climate change, invasive species, water scarcity, and habitat fragmentation. The goal of this project will be to provide the SALCC an action plan for use in future efforts to integrate optimal sustainability strategies for natural and cultural resources. The project will identify areas of overlap and disjunction between optimal methods of natural resource sustainability and cultural resource sustainability. Within this framework, cultural...

These heatmaps show a top 3 montane habitat fragmentation and loss stressor, as ranked by participants, and the concentration of participants who reported as working in each municipality or county who also voted for that stressor across the landscape. Symbology represents the percentage of participants with 0% = dark green, 0.0001 % - 24.99% = light green, 25% - 49.99% = yellow, 50% - 74.99% = orange, 75% - 100% = red. All counties and municipalities identified by participants as areas where they work were given a tally for each of the top 3 stressors that participants chose. Counties with a small number of participants were not adjusted for small sample size. These results were shared via a webinar hosted by the...

In Hawaiʽi and elsewhere, research efforts have focused on two main approaches to determine the potential impacts of climate change on individual species: estimating species vulnerabilities and projecting responses of species to expected changes. We integrated these approaches by defining vulnerability as the inability of species to exhibit any of the responses necessary for persistence under climate change (i.e., tolerate projected changes, endure in microrefugia, or migrate to new climate-compatible areas, but excluding evolutionary adaptation). To operationalize this response-based definition of species vulnerability within a landscape-based analysis, we used current and future climate envelopes for each species...

Expansion of deadly, mosquito-borne bird diseases such as avian malaria into Hawaiʽi’s high elevation forests as a result of global warming is one of the most significant threats facing the state’s rare native forest birds. Few practical options for control of disease-carrying mosquitoes over large landscapes are available, however. The best hope for remaining species of native birds may be the development of tolerance or resistance to this introduced disease. Therefore, understanding how tolerance and resistance evolve and developing ways to speed this process may be good proactive strategies for addressing impacts of climate change. We evaluated ways to rapidly measure a bird’s natural immunity with the hope that...

The RCMAP (Rangeland Condition Monitoring Assessment and Projection) dataset quantifies the percent cover of rangeland components across the western U.S. using Landsat imagery from 1985-2020. The RCMAP product suite consists of eight fractional components: annual herbaceous, bare ground, herbaceous, litter, non-sagebrush shrub, perennial herbaceous, sagebrush, shrub and rule-based error maps including the temporal trends of each component. Several enhancements were made to the RCMAP process relative to prior generations. We used an updated version of the 2016 base training data, with a more aggressive forest mask and reduced shrub and sagebrush cover bias in pinyon-juniper woodlands. We pooled training data in areas...

This raster dataset quantifies the relative flow patterns of structural sagebrush connectivity in the sagebrush biome at 270-meter resolution. Connectivity was calculated using an omnidirectional circuit-based algorithm, with sources, targets, and conductance based on sagebrush fractional component from the RCMAP sagebrush products for 1985, 1990, 1995, 2000, 2005, 2010, 2015, and 2020. Normalized cumulative current density was used to represent relative flow of connectivity and binned into 3 relative flow classes (impeded, diffuse, and channelized flow). We calculated the relative flow temporal trends for channelization and impedance between 1985 and 2020 to identify areas that were becoming more channelized or...

The South Atlantic Conservation Blueprint is a living spatial plan to conserve natural and cultural resources for future generations. It identifies shared conservation priorities across the South Atlantic region. The second iteration of the Blueprint, Version 2.0, was released in July 2015. It was a completely data-driven plan based on ecosystem indicator models for terrestrial, freshwater, and marine environments, as well as a connectivity analysis. Blueprint 2.0 used a 200 m spatial scale. With Version 2.0, the total number of people actively involved in developing the Blueprint grew to more than 400 individuals from over 100 organizations.

Past analysis has shown that temperature-dependent avian malaria is likely to reduce overall available Hawaiian forest bird habitat with temperature increases. We used a comprehensive database of forest bird sightings (over 42,000 points), the most up to date regional climate projections and state-of-the-art ensemble species distribution models to project shifts in distribution of all Hawaiian forest bird species due to climate change. Our results show that all forest bird species are expected to suffer large range losses by end of this century with single island endemics at a greater risk than more widespread species. Because most species require structurally complex forest habitat that may take decades to develop,...
