Lack of complete snow cover for the past 3 winters in southwestern Alaska has forced agencies to postpone conducting moose surveys due to the likelihood of underestimating the population/lack of comparability to previous surveys. Poor snow conditions are known to lower the sightability of moose, yet, for most regions of Alaska, the variation in moose sightability during suboptimal conditions has not yet been quantified. Because scientists are predicting less snowfall in this region over the long term, research was initiated to estimate sightability correction factors (SCFc) to apply to abundance estimates.

The primary objective of this project is to develop a short synthesis report assessing 11 habitats, using a variety of ecological indicators. The report will be one tool that the South Atlantic LCC can use to inform decision-makers, stakeholders, and the general public about the health of South Atlantic habitats. To achieve this project, six discrete project tasks have been identified and are outlined in the next section.1) Project start-up and pre-workshop preparation: IAN will carefully review the Conservation Blueprint habitats and the indicators used to assess the health of these habitats. We will become familiar with the thresholds and data analysis that the South Atlantic LCC is using for their project. This...

Many ecosystem models, particularly those that are “mechanistic” (based on an understanding of processes), are over-parameterized (not identifiable). As a result, model parameters are selected (not estimated using an optimization technique), parametererror/covariance terms become extremely difficult to estimate, and Monte Carlo error propagation does not adequately capture the effect of all uncertain model terms. In those situations, techniques that evolved from Regional (Generalized) Sensitivity Analysis (RSA), such as Generalized Likelihood Uncertainty Estimation (GLUE), Bayes Monte Carlo, and Markov Chain Monte Carlo (MCMC), are preferred techniques for model error propagation. These techniques can be used to...

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 fourth iteration of the Blueprint, Version 2.2, was released in November 2017. It used comparable methods and the same spatial scale as Blueprint 2.0 and 2.1, just incorporating updated information for many of the indicators. Version 2.2 was a completely data-driven plan based on ecosystem indicator models for terrestrial, freshwater, and marine environments, as well as a connectivity analysis. It used a 200 m spatial scale. More than 500 people from 150 organizations participated in the development...

A comparison of hydrologic simulations in the lower Apalachicola-Chattahoochee-Flint River Basin, southeastern United States. This project provides technical assistance in integrating the Waterfall instream flow models developed for the South Atlantic LCC by RTI with the PRMS models being developed in the neighboring Gulf Coastal Plains and Ozarks LCC.

In recognition of the importance of salmon to the economy and ecosystems of southwestern Alaska and the pervasive influence of water temperature on salmon, voluntary network-based water temperature monitoring programs were established in the Bristol Bay region and the Kodiak Archipelago in 2015. These collaborative networks among federal and state agencies, non-governmental organizations and Native Tribes aim to provide reliable time-series stream and lake temperature data to support development of proactive approaches to management of salmon in response to climate warming. Collaborators are tackling the challenges of year-round field deployment, data management, data storage and sharing, and long-term funding....
This visual guide documents the work gathering and analyzing data on caves and karst resources in the Appalachian LCC. The maps and files provide a comprehensive overview of data available for examining relationships between environmental factors and biological diversity and distribution within karst areas in the region. This visual survey is intended to be a guide to what the researchers have accomplished, and a guide to what new questions and results would be interesting to end-users.

The Appalachian LCC is currently engaged in an effort to develop a draft regional conservation plan for the Cooperative using an interactive and iterative spatial prioritization framework. Using available data and modeling approaches that are well supported in the literature, researchers from Clemson University are developing conservation planning models that include site selection, ecological threat assessments, and broad ranging habitat and ecological connectivity analyses.The research team is working closely with designated technical teams from each major region in the Appalachian LCC to offer unique insights and input to help guide the interactive conservation planning process. After each round of feedback,...

Provision of shade via riparian restoration is a well-established management adaptation strategy to mitigate against temperature increases in streams. Effective use of this strategy depends upon accurately identifying vulnerable, unforested riparian areas in priority coldwater stream habitats. An innovative riparian planting and restoration decision support tool is now available to the conservation community. This user-friendly tool allows managers and decision-makers to rapidly identify and prioritize areas along the banks of rivers, streams, and lakes for restoration, making these ecosystems more resilient to disturbance and future changes in climate.This research developed and implemented a user-friendly web-based...

The Fish Creek Watershed encompasses diverse aquatic habitats representative of much of the Arctic Coastal Plain of northern Alaska. Beyond surface water and permafrost responses caused by changes in climate, this landscape is also subject to potential land-use impacts related to petroleum development in the National Petroleum Reserve – Alaska (NPR-A). Thus, this region is an ideal setting to address aquatic habitat questions of longstanding interest to Arctic resource managers, scientists, and other stakeholders. Our multidisciplinary team is focusing on broad hypothesis that surface-water availability, connectivity, and temperature mediate aquatic habitats and trophic dynamics. We are working to understand and...
The Bureau of Land Management- Arctic Field Office has a requirement for coordinating research andmonitoring projects related to the effectiveness of stipulations and surface resource impacts in theNational Petroleum Reserve - Alaska. Yellow-billed Loons are among the least common breeding birdsin the mainland United States and the U.S. breeding population is concentrated largely within theNational Petroleum Reserve – Alaska (NPR-A). Interest in developing the oil and gas reserves withinNPR-A has increased within the last 10 years, along with a need for better information with which toprotect loon populations. Fundamental to protection strategies is a good understanding of distributionand abundance.In 2007, the...
