Refinement of Gopher Tortoise Habitat Identification and Related Land Cover Data. The benefits of this project include: 1) much improved gopher tortoise remote habitat identification that could have a strong influence on potential listing status (with the likelihood that significantly more habitat may be identified); 2) better statewide land cover data regarding scrubby flatwoods and potentially refined mesic flatwoods and dry prairie classifications; and 3) potential spin off benefits regarding better habitat identification for related species such as gopher frogs and other xeric adapted species that might be found in on drier flatwoods and dry prairie sites.Continuation of Water Restoration Analyses.

This project utilizes projected visualization of land cover conditions for the state of Florida at three future time periods. Simulated projected future conditions also vary by patterns in development, levels and types of conservation, and sea level rise. These visualized scenarios afford the opportunity to examine a range of possible outcomes for land use and land cover, and use these scenarios to evaluate the impacts on potential habitat distributions for focal species. For this project, focal species were centered within the Florida Panther National Wildlife Refuge and impacts. The methodology for this project includes four major steps, which have been found to be effective in previous scenario analyses with...

This carbon sequestration research is part of a new pilot grassland conservation program to protect at-risk grasslands from conversion to cropland in the northern Great Plains. Natural resources partners have leveraged more than $3 million in private and federal funding to support an innovative program that extends protection of privately-owned grasslands that have expired under the Conservation Reserve Program (CRP). In the past two years alone, the number of CRP acres nationally has dropped from 31.2 million to 27 million. Of the 4.2-million-acre-decline, lands lost in North Dakota and Montana accounted for 1.6 million acres, or 38 percent. The program aims to encourage private landowners to conserve CRP grasslands...

Temperate grassland ecosystems are imperiled globally, and habitat loss in North America has resulted in steepdeclines of endemic songbirds. Commercial livestock grazing is the primary land use in rangelands that supportremaining bird populations. Some conservationists suggest using livestock as “ecosystem engineers” to increasehabitat heterogeneity in rangelands because birds require a spectrum of sparse to dense vegetation cover.However, grazing effects remain poorly understood because local studies have not incorporated broad-scaleenvironmental constraints on herbaceous growth. We surveyed grassland birds across a region spanning26 500 km2 in northeast Montana, United States to assess how distribution and abundance...

Within the time frame of the longevity of tree species, climate change will change faster than the ability of natural tree migration. Migration lags may result in reduced productivity and reduced diversity in forests under current management and climate change. We evaluated the efficacy of planting climate-suitable tree species (CSP), those tree species with current or historic distributions immediately south of a focal landscape, to maintain or increase aboveground biomass, productivity, and species and functional diversity. We modeled forest change with the LANDIS-II forest simulation model for 100 years (2000–2100) at a 2-ha cell resolution and five-year time steps within two landscapes in the Great Lakes region...

Mapping of barriers and statistical prediction of their passability is now fairly complete in the Great Lakes basin, yet field assessments of barrier characteristics and passability to migratory fishes are spotty. We will use the Lake Michigan basin as a pilot area for comprehensive field assessment of dam condition, dimensions, and passage technologies. These characteristics will be incorporated into our barrier database, enabling improved estimates of removal costs, watershed cumulative passability, and infrastructure maintenance challenges. In parallel, we will conduct field assessments of passability to spring migrations of Great Lakes fishes in 15 Wisconsin watersheds. Recording the upstream limits of migrations...

Working within the constraints of the SWAP revision timeline, we propose to advance biodiversity conservation within the region by enhancing the regional effectiveness of SWAPs and the ability of the LCC to address regional biodiversity priorities. We propose to accomplish these outcomes through engagement of SWAP coordinators and LCC professionals in the creation of a set of detailed best practices and learning resources tailored to needs that they help to identify. We will regularly engage with the SWAP coordinators as we develop these resources to allow each state to influence and employ the resources as needed, recognizing that time and resources to participate in this project will vary among states. As part...

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...
