This data set was collected as part of a structured decision-making workshop designed to identify sources of uncertainty and articulate alternative hypotheses about prescribed fire in high marshes of the Gulf of Mexico. Workshop participants independently scored alternative hypotheses based on a standard rubric using an online system. Following the workshop, we used the scores to compute QVoI for each participant. We used QVoI to prioritize the sources of uncertainty based on their magnitude of uncertainty, relevance for decision making, and reducibility.

These datasets were compiled during the development and application of an adaptive management framework for the conservation and recovery of Eastern Black Rails in the Atlantic Coast Joint Venture Region. The study is conducted in cooperation with the Eastern Black Rail Working Group of the Atlantic Coast Joint Venture. U.S. Geological Survey and the Atlantic Coast Joint Venture are working with partners to test alternative methods of manipulating coastal marsh and other wetland habitats to make them suitable for Black Rails with the long-term goal of stabilizing or reversing population declines. The objectives of this project are to develop an adaptive management framework that allows wetland managers to reduce...
The eastern black rail (Laterallus jamaicensis jamaicensis; hereafter rail) is a small, cryptic marshbird that was recently listed as threatened under the U.S. Endangered Species Act. We organized a rapid prototyping workshop to initiate development of an adaptive management for rails on the Atlantic Coast. The in-person workshop spanned 2.5 days and was held in Titusville, Florida in January 2020. Workshop participants, comprised of species experts and land managers of rail habitats, chose to focus the framework on testing habitat management techniques to maximize rail occupancy, in which uncertainties could be reduced through a combination of field management experiments and coordinated monitoring. We used the...

U.S. Geological Survey and partners are testing the effects of prescribed fire on Black Rails, Yellow Rails, and Mottled Ducks in the high marsh habitats of the northern Gulf of Mexico region. The study is conducted in cooperation with Mississippi State University, Illinois Natural History Survey, U.S. Fish and Wildlife Service, state agencies, universities, and non-governmental organizations. The objectives of this project are to develop an adaptive management framework that allows land managers to reduce our uncertainty about the effects of prescribed fire on these species and the habitats on which they depend, and give managers tools and information that will help them determine the best management actions to...
We conducted ground-based surveys at 589 randomly selected 16-ha plots on the Yukon-Kuskokwim Delta, Alaska during 2015-2016. The plots were selected using a stratified random sampling plan in an area of 35,769 square km divided into 8 physiographic strata. The population totals from the stratified random design estimators were adjusted using detection ratios derived with a double sampling protocol (Bart and Earnst 2002) on a subset of plots in Alaska.The subset of plots used for double sampling included 17 study plots on the Yukon Delta National Wildlife Refuge (9 plots in 2001-2002 [McCaffery et al. 2012] and 8 plots in 2016), and 33 plots located on the North Slope of Alaska (Utqiaġvik [6 plots, 2014–2015], the...
We conducted population and habitat assessments for Mountain Plovers in Texas during winters of 2019 and 2020. We used roadside surveys and distance-sampling to estimate bird density and calculate population totals for the study area, which included parts of five ecoregions (Chihuahuan Deserts, High Plains, Central Great Plains, Southern Texas Plains, Texas Blackland Prairies, and Western Gulf Coastal Plain). In 2019, we surveyed 103 transects along 3,032 km (1,884 mi) and, in 2020, we surveyed 152 transects along 4,985 km (3,098 mi). When driving along transects, we stopped every 3.2 km (2 mi) to assess habitat conditions (vegetation height, vegetation density, etc.) and land cover (National Land Cover Database...

This data set was collected as part of structured decision-making workshops designed to build a Bayesian Decision Network of prescribed fire in high marshes of the Gulf of Mexico. As part of a formal elicitation process for expert judgment, workshop participants independently created conditional probability tables based on a conceptual model of prescribed fire in high marsh ecosystems. Following the workshop, we aggregated the conditional probability tables across experts and used them to create a Bayesian Decision network in probability network software.
