Information on the nature and distribution of permafrost is critical to assessing the response of Arctic ecosystems to climate change, because thawing permafrost under a warming climate will cause thaw settlement and affect micro-topography, surface water redistribution and groundwater movement, soil carbon balance, trace gas emissions, vegetation changes, and habitat use. While a small-scale regional permafrost map is available, as well as information from numerous site-specific large-scale mapping projects, landscape-level mapping of permafrost characteristics is needed for regional modeling and climate impact assessments. The project addresses this need by: (1) compiling existing soil/permafrost data from available...
Speaker: Dr. Jason Kreitler, USGSWednesday, October 24, 2012 -12:00pm to 1:00pmThis project is analyzing downscaled climate model data to assess the geography of climate change at scales relevant to actual conservation actions. This work analyzes the California Essential Habitat Connectivity products to determine which protected lands are most vulnerable and which of the proposed corridors would partially mitigate climate change threats.
This dataset consists of the current distribution (2000s) of mangrove forests in the southeastern U.S. This dataset was created from the current best available mangrove data on a state specific basis. Florida mangrove data was extracted from Florida Landuse Land Cover Classification System (FLUCCS). For Louisiana, we used observations of mangrove stands from aerial surveys by Michot et al. (2010). Mangrove presence in Texas came from maps produced by Sherrod & McMillan (1981) and the NOAA Benthic Habitat Atlas of Coastal Texas (Finkbeiner et al. 2009). Please note that this map depicts the distribution of mangrove forests and not mangrove individuals. More detailed information on this dataset is available in Osland...

This project established a permafrost monitoring network in this region, providing a baseline of permafrost thermal regimes for assessing future change at a total of 26 automated monitoring stations. Stations have collected year-round temperature data from the active layer and the permafrost starting from the summer of 2011. The strong correspondence between spatial variability in permafrost thermal regime and an existing ecotype map allowed for the development of a map of ‘permafrost thermal classes’ for the broader study region. Further, the annual temperature data was used to calibrate models of soil thermal regimes as a function of climate, providing estimates of both historic and future permafrost thermal regimes...
Strong evidence on climate change underscores the need for actions to reduce the impacts of sea-level rise. Global mean sea level may rise 0.18–0.48 m by mid-century1, 2 and 0.5–1.4 m by the end of the century2. Besides marine inundation, it is largely unrecognized that low-lying coastal areas may also be vulnerable to groundwater inundation, which is localized coastal-plain flooding due to a rise of the groundwater table with sea level. Measurements of the coastal groundwater elevation and tidal influence in urban Honolulu, Hawaii, allow estimates of the mean water table, which was used to assess vulnerability to groundwater inundation from sea-level rise. We find that 0.6 m of potential sea-level rise causes substantial...
Final report for the project titled “Field Monitoring and Analysis of Climate Change Across a Wide Range of Ecosystems in Hawai‘i”
The Weather Research and Forecasting (WRF) model has been configured as a regional climate model for the Hawaii region (HRCM) to assess the uncertainties associated with the pseudo–global warming (PGW) downscaling method using different warming increments from phase 5 of the Coupled Model Intercomparison Project (CMIP5) model experiments. Results from 15-km downscaling experiments using warming increments from 10 individual CMIP5 models for the two warming scenarios representative concentration pathway 4.5 (RCP4.5) and 8.5 (RCP8.5) are compared with experiments using multimodel mean warming increments. The results show that changes in 2-m temperatures, 10-m wind speed, rainfall, water vapor path, and trade wind...

Understanding how climate change is affecting Hawaii’s high-elevation ecosystems: an assessment of the long-term viability of Haleakala silverswords and associated biological communities Final Report
Although climate change is predicted to place mountain-top and other narrowly endemic species at severe risk of extinction, the ecological processes involved in such extinctions are still poorly resolved. In addition, much of this biodiversity loss will likely go unobserved, and therefore largely unappreciated. The Haleakalā silversword is restricted to a single volcano summit in Hawai‘i, but is a highly charismatic giant rosette plant that is viewed by 1–2 million visitors annually. We link detailed local climate data to a lengthy demographic record, and combine both with a population-wide assessment of recent plant mortality and recruitment, to show that after decades of strong recovery following successful management,...

This project resulted in an extensive mapping of coastal change along the entire coastline of the Western Alaska Landscape Conservation Cooperative (LCC). The work provides important baseline information on the distribution and magnitude of landscape changes over the past 41 years. The extent of change to the coastline and to coastal features, such as spits, barrier islands, estuaries, tidal guts and lagoons, was known to be substantial in some areas along the coast (e.g., portions of the Yukon–Kuskokwim Delta), although the extent of change along the full Bering Sea coast was not well documented. With this analysis, changes can be summarized for different land ownerships or other units to assess the extent of recent...

FY2014One of the primary challenges facing public land managers in the Great Basin is identifying adaptation strategies to increase resiliency to climate change in an area that is already struggling with profound environmental challenges. Recent efforts to understand how the Great Basin weathered past droughts and climate variability may offer insight into approaches that could work in future decades. One approach to gather this information is to understand Traditional Ecological Knowledge (TEK). Gathering this information is challenging and requires an acknowledgment that much of this information is highly sensitive and proprietary. Translating this information into actionable management plans is even more challenging.This...
FY2014The goals for the project are1) Develop a Walker River Vision document which will include Traditional Ecological Knowledge (TEK) of the traditional plants, wildlife, fish and water located on the reservation and traditional hunting/ gathering areas of the Agai Dicutta Numa (Walker River Paiutes) for use in future resource management planning and cultural sustainability..2) Develop a pilot project along the Walker River on the reservation by planting willows and other traditional plants to determine best practices for re-vegetation.This project will focus on GBLCC Goal 2: Focus science and management actions to sustain natural resources in the context of changing environmental conditions.The proposed project...
