AERC staff hang bat detection microphonesLittle Brown Bat Survey
Joint Base Elmendorf-Richardson
August 2016 to April 2018

 Little brown bats (myotis lucifugus) nationwide are suffering massive die-offs associated with a fungal disease known as White Nose Disease Syndrome. The State of Alaska has identified little brown bats as a species of special concern and federal protections under the Endangered Species Act could follow.  Joint Base Elmendorf-Richardson (JBER) is known to support little brown bat populations which are currently unmonitored. AERC will implement a bat survey on JBER to determine the presence of bats, estimate their abundance, and identify their preferred habitats. Methods pioneered during this survey will give JBER land managers the tools they need to better monitor and, if necessary, protect bat populations on the installation.

•    Conduct bat monitoring using acoustic bat detection equipment and share data with the Bat Acoustic Monitoring Portal (BatAMP)
•    Improve upon existing monitoring practices by identifying behavioral patterns and vocalizations which are unique to bats in the area.
•    AERC staff will conduct field work, produce written reports, and make recommendations based on the results of the survey.

 

AERC staff deploy barrior netting in the Eagle RiverSalmon Abundance and Diversity in Eagle River
Joint Base Elmendorf-Richardson
August 2016 to February 2018

The mouth of the Eagle River on Joint Base Elmendorf-Richardson (JBER) is a critical late summer feeding area for Cook Inlet’s endangered population of beluga whales. Little is known, however, about the run size and timing of the salmon that the whales prey on in this river. Historic sampling methods for studying Pacific salmon in the Eagle River have been deemed inadequate and new methods are needed. AERC staff are working to investigate, coordinate, and implement new techniques for measuring and monitoring salmon diversity and abundance in the river. The techniques and data established during this study will allow state and federal wildlife managers to better understand salmon populations in the Eagle River and their importance to Cook Inlet’s belugas.

•    Devise new methods of sampling and quantifying Pacific Salmon populations in Eagle River
•    Provide senior technical support to JBER fisheries program throughout the salmon sampling season.
•    AERC engaged with industry partner will provide fisheries science expertise to establish and oversee sampling program.

AERC team documents archaeological features at Kahuku Training AreaIntensive Archaeological Survey and Testing in Kahuku Training Area
Oahu, Hawaii
September 2015 to December 2017

The Kahuku Training Area (KTA) is located on the windward side of the island of Oahu and is used by the U.S. Army for various forms of combat training. This part of Oahu was the site of many pre-contact Hawaiian settlements and the setting for some of the island’s earliest and best-known legends. From August 4 to September 1 of 2016, a team of AERC archaeologists from the University of Alaska conducted an intensive survey of selected portions of the training area, during which they documented 13 new archaeological sites and performed condition assessments at five previously recorded sites. Their findings included five traditional Hawaiian residential and agricultural sites, five postcolonial agricultural sites, one religious site, and six sites of undetermined affiliation. As a result of the survey, three new sites were recommended eligible for the National Register of Historic Places.

  • Complete an intensive archaeological pedestrian survey by integrating subsurface testing to identify cultural remains or verify surface indications of features. 
  • Document new sites sufficiently so they could be evaluated for National Register eligibility.
  • Assess documented sites to determine if there has been a change in condition or identify undocumented features.

Moose Browse and Winter Habitat Survey
Joint Base Elmendorf-Richardson
October 2017 to March 2019

Moose are an economically important species in Alaska and provide cultural, financial, and subsistence benefits to Alaskans living in the Anchorage Municipal and Mat-Su Valley regions.  To date, there has not been an assessment of the effectiveness of the moose browse habitat enhancement activities that have been established on Joint Base Elmendorf Richardson (JBER). AERC, in partnership with the University of Alaska Anchorage and the Institute for Economic and Social Research (ISER), will evaluate JBER’s moose browse management areas to determine their quality and successional state. The team will then make recommendations for the ongoing management of JBER’s moose habitat.  

  • Review management reports, enhancement plans, and GIS data on enhanced moose browse locations.
  • Survey habitat enhancement plots for current quality and availability of moose browse.
  • Modify and update moose management plans based on the information gathered from reviews and surveys.

Wetland Monitoring
Joint Base Elmendorf-Richardson
October 2017 to March 2019

The Ship Creek watershed on Joint Base Elmendorf-Richardson is highly dynamic and has an extensive history of flooding. Significant damage has been incurred during major storm events in recent years. Changes to bank stability and stream course have the potential to affect adjoining wetlands and other buffers, and subsequently nearby development and infrastructure. In the interest of mitigating potential future flood hazards, AERC will conduct wetland functional assessment and monitoring of portions of the Ship Creek watershed within JBER’s installation boundaries.

  • Use GIS analysis to conduct wetland functionality assessment on the Ship Creek watershed.
  • Identify areas for hazard mitigation.
  • Prepare a vegetation mapping signature book series for riverine and floodplain wetlands on JBER

 

Coastal Erosion along Alaska's Northern coast
Coastal Erosion Study
Oliktok and Barter Island Long Range Radar Sites, North Slope of Alaska
October 2017 to December 2019

Previous studies have shown that the U.S. Air Force radar sites at Oliktok and Barter Island are especially vulnerable to increased coastal erosion taking place along the Arctic coast of Alaska. Accurate predictive modeling of future erosion at these sites is needed in order to assess potential impacts to their facilities. AERC has partnered with researchers from the University of Alaska Anchorage’s College of Engineering and BEM Systems, Inc. to develop comprehensive predictive models of shoreline positions over the next 50 years. These models will account for expected increases in coastal erosion due to climate change and help to inform the U.S. Air Force’s decision-making process.

  • Perform remote field work to document oceanographic conditions and collect sediment core samples from onshore and offshore areas adjacent to the sites.
  • Develop site-specific erosion models which incorporate Global Climate Model predictions and local data gathered during the research and field work phases.
  • Evaluate models generated by the project and determine their predictive skill through comparisons to existing models and a rigorous 3rd party Quality Assurance/Quality Control process.
