Webinar Descriptions

Assessing Climate Change Vulnerabilities and Adaptation Opportunities for USFWS in the Midwest

  • Details: We are working with the U.S. Fish and Wildlife Service in the Midwest United States to enhance climate change adaptation efforts on refuges and wetland management districts. During the first phase of the project we worked with U.S. Fish and Wildlife Service personnel to develop a watershed-based climate change vulnerability assessment. The vulnerability assessment combines fifteen different climate change indicators based on changes in temperature, precipitation, and hydrology. The change in each of these indicators from the baseline period (1986-2005) to the future period (2040-2059) is consolidated into a composite score for each watershed. Landscape scale metrics related to each watershed’s adaptive capacity were combined with the climate change impact indicators to produce a vulnerability score and mapped across the region. Next, we held virtual discussions with several field stations on the recent and projected climate change impacts and their adaptation efforts and challenges. We identified key components of current adaptation efforts along with barriers and opportunities to advancing future adaptation strategies. Using insights from these conversations we selected a habitat to serve as a case study to evaluate our vulnerability assessment tool and develop region-wide adaptation thinking strategies that will aid field stations as they continue to prepare for future changes.

Comprehensive Geolocation of Preferential Groundwater Discharges Using Heat Tracing Techniques

  • Details: Discharge of groundwater to surface water bodies is often highly preferential in space, so that a relatively small fraction of the sediment/water interface controls the transfer of heat, gas, and dissolved chemistry from aquifer to channel. Therefore, preferential discharges are not well captured by random and transect-based sampling regimes, particularly at large scales. Recent advances in spatially distributed temperature sensing techniques using remote thermal infrared and direct-contact fiber-optic methods allow comprehensive detection of preferential discharge zones. We show how radiometric infrared data collected with small drones along mountain streams can be used to pinpoint discharges in rugged terrain that are easy to miss with ground-based surveys. Handheld infrared data are more practically collected from watercraft along lowland rivers, guiding geochemical and age dating sampling over 10’s of km in “real time”, such that discharging groundwater can be tied to watershed-scale numerical models. However, remote sensing with thermal infrared cannot penetrate the water column, so submerged discharges may be missed. In cases where niche groundwater-based aquatic habitat characterization necessitates subsurface detail, fiber-optic cables can be deployed along the sediment-water interface to collect fine scale (e.g. 0.25 m) temperature patterns over space and time. We debut a new graphical user interface software that can be used to quickly process fiber-optic data by calculating various statics that may indicate discharge processes, and by automatically plotting data in map view, efficiently enabling geolocation. The combined advances in sensor technology and post-processing software are bringing reconnaissance-based heat tracing solidly into the applied surface water/groundwater exchange characterization toolkit.

Dendrochronology to Inform Management of Floodplain Forests in the Upper Mississippi River Basin

  • Details: Maintaining the ecological and economic services of floodplain forests in the Upper Mississippi River System requires strategic forest management. Toward that end, we have been researching tree growth response to environmental variability at two sites along the Upper Mississippi River. Dendrochronology is a powerful tool that has historically been underutilized in floodplain forests, partially due to the challenge that the ring-porous anatomy of dominant species poses for crossdating. This collaborative project leverages the new DendroElevator online platform for tree-ring image analysis to measure and crossdate growth rings from dominant taxa at two sites in the upper Mississippi Basin. Emergent results suggest that silver maple age is variable between and within sites, green ash anatomy may reflect flood activity, and cottonwood recruitment predates that of silver maple in certain stands. Silver maple crossdating reinforced the visual identification of “false rings,” intra-annual changes in wood density due to local dormancy and reactivation of the vascular cambium within a single ring. Comparisons of ring width variability to environmental parameters reveal a positive response in silver maple growth to increased streamflow. Anatomical irregularities (“flood rings”) in ash are shown to be widely present in the notable flood year of 2001. Dendrochronology can inform how silver maple stands developed and how that development was influenced by environmental factors including hydrology which can support restoration efforts in establishing new age cohorts. These observations have implications for future management regarding forest treatments and water levels, especially in light of projected climate and land-use changes in future decades.

Improving Suspended-Sediment Flux Measurements in Coastal Waterways

  • Details: Accurate measurements of suspended-sediment flux measurements in coastal settings are of increasing interest, given the importance of sediment supply to coastal resiliency as sea level rises and the transport of associated nutrients and pollutants on suspended-sediment. However, measuring fluxes in tidal systems is especially difficult given that the total flux is the sum of two large numbers that are often an order of magnitude greater than the residual flux. This webinar will detail new approaches for measuring suspended-sediment flux developed by the San Francisco Estuary Sediment Transport Project of the United States Geological Survey California Water Science Center. A new approach is needed because current methods for measuring suspended-sediment flux require that the vertical suspended sediment concentration (SSC) profile is fixed. In tidal systems, factors that control the vertical SSC profile—vertical mixing controlled by water velocity, and downward settling of suspended sediment mediated by flocculation of cohesive sediment—constantly vary through each tide and may exhibit systematic differences between flood and ebb tides (e.g., tidal asymmetries in water velocity or particle size). For a monitoring site in the San Francisco Estuary, accounting for changes in the vertical SSC profile when estimating sediment flux changed not only the magnitude but also the direction of previously published net sediment flux measurements. Results of this work indicate that changes in the vertical profile of suspended sediment should be considered when estimating suspended-sediment fluxes.

Improving the science and management floodplain forests in the Upper Mississippi River System

  • Details: Inundation regimes drive the form and function of floodplain ecosystems in the Upper Mississippi River System (UMRS). Despite their importance, inundation regimes have not been systemically characterized in spatially-explicit ways that would advance understanding of ecological processes or inform management actions in the UMRS. In this presentation, I will share work my colleagues and I have done to systematically describe inundation dynamics across 2.6 million acres of the UMRS in ecologically relevant ways and discuss how the model is being used by both research scientists and the management community. The model itself integrates topo-bathymetric terrains and 40 years of daily water surface elevations to summarize long-term patterns of surface water dynamics including inundation event frequency, duration, depth, and timing. Distributions of these attributes vary within and among multiple levels of river organization, including navigational pools and geomorphic reaches. Non-linear relationships among inundation regime attributes and their geospatial distributions likely reflect complex interactions among topographic, hydrologic, and anthropogenic constraints on flooding dynamics. The model is used by research scientists to understand the role of flooding in forest succession dynamics, to identify hydrologically sensitive areas, and to establish eco-hydro-geomorphic relationships. It is also being used by the management community to enhance communication, inform decisions, and develop restoration strategies in the UMRS. The variety of inundation model applications demonstrates the importance of spatially explicit inundation models for developing robust, process-based relationships that inform floodplain ecology and management.

Learning from the ‘Great Floods’ of the Missouri River: what they tell us about resilient river management

  • Details: Recent flooding on the Lower Missouri River – especially in 2011 and 2019 – has engendered calls for re-examining how the river and its floodplain are managed. Despite being downstream from the largest reservoir system in North America, this recent flooding has resulted in billions of $US in damages. My analysis of the effects of “Great Floods” since 1990 is intended to inform options for flood-risk reduction and increased resilience to large floods. Extent and effects of flooding are highly spatially variable because of the interaction of two factors: 1) floods in this very large drainage basin arise from very different origins (snow melt in the Rockies to moisture advected from the Gulf of Mexico) and 2) ongoing geomorphic adjustments to channelization, levees, and interruption in sediment continuity have created reaches with highly variable flood conveyance. A statistical analysis of 2011 and 2019 levee breaks indicates that low-conveyance reaches with greater aggradation and narrower batture zones have higher probabilities of breaks, leading to the potential to target flood-risk mitigation efforts in those areas. In addition, despite considerable hydrologic variability, recent trends of increasing wetness have become apparent in Missouri River hydrologic time series. Recognition of these trends indicates that non-stationarity will be a factor in mitigation designs. Among mitigation scenarios, implementation of a flow corridor has emerged as an option with potential benefits for increasing resilience through both flood-risk reduction and increased conservation values.

Near Real-time Ecological Assessment Tools Based on Hydrologic Monitoring Gauges

  • Details: Staff from the USFWS, USGS, Everglades National Park, South Florida Water management District, and US Army Corps of Engineers have been utilizing a near real-time animated online hydrologic model to assess ecological conditions in the Greater Everglades. Hydrologic data from gauges in the Everglades Depth Estimation Network (EDEN) are used to produce statistical analyses, animated maps, and ecological conditions reports for various species including the Wading Bird Depth Viewer (WADEM) and Cape Sable Seaside Sparrow Viewer. All of this data is available online and helps to provide recommendations for water management operations in the Greater Everglades through our interagency Periodic Scientist Calls and Multi-species Water Coordinator meetings.

New Hydrologic Analysis Tools for Resource Managers

  • Details: Over the past two years, the USFWS Southeast Region has collaborated with USGS to develop regional tools to better understand water resources on National Wildlife Refuges. These tools include a DOI lands Flood Event Viewer and an R package that generates a summary of available water quality data for a refuge or watershed. The Flood Event Viewer allows users to interactively explore (via a map viewer) peak coastal and inland water levels associated with tropical cyclones or other major flood events. The tool can also generate summary reports of available monitoring data within a specified distance of a refuge or national park unit or generate a regional summary report for 1-2 selected storm events. The R package allows users to generate a summary report including tabular and graphical statistical summaries of available water quality data (retrieved from the Water Quality Portal maintained by USGS and EPA) for a refuge or specified watershed at the HUC8 or HUC10 scale. Users may select specific parameters of interest or default parameter groups to include in the report. The tools were funded and developed for the Southeast Region's Inventory and Monitoring Branch but are applicable nationwide. This presentation will provide an overview of the tools that have been developed and a demonstration of their use.

Rapidly Changing Transport Conditions in a Vegetated Marsh

  • Details: The seasonal regrowth of vegetation is a primary control on the physical environment in deltaic marshes, influencing both the connections with the channel and the transport environment on the marsh. It has often been pointed out that the revegetation event and the spring flood are not synchronized in the same way each year, a fact that adds uncertainty to operation plans for managed marshes. We used dye injections, hydroacoustic instrumentation, sediment traps, water samples, and monthly vegetation surveys to link the rapidly changing vegetation conditions throughout the spring flush with flow and velocity on the marsh and monthly sediment deposition. Our data were collected in a freshwater marsh (dominated by Typha, Colocasia, and Alternanthera) in the Mississippi River Delta during the Mississippi River floods of 2018 and 2019. The 2019 flood is notable as a long event that kept water level and incoming flow conditions nearly constant for many months. This allowed the project team to isolate and observe the changes to the transport system that were due to vegetation growth alone. We use this novel data set to document and explain profound changes in flow conditions and routing during the flood season, and apply the lessons learned to restoration and management practice. We find that the ability of the marsh to receive and retain sediments changes markedly throughout the growing season. The dominant driver is the density of submerged aquatic vegetation, which reaches a peak in late spring, corresponding to a period of diminished sedimentation.

Salt Marshes and Sea Level Rise

  • Details: The presentation starts with a description of salt marshes, how they function, what lives there, and their importance to both their floral and faunal inhabitants and to humans - how they protect us against storm surges, absorb pollutants, etc. In the face of sea level rise, marshes, in order to persist, will have to either increase their elevation at a rate equivalent to SLR (which is accelerating) by accumulating litter and sediments, or migrate inland. Many marshes in the northeast and mid-Atlantic are not accreting fast enough and are showing signs of stress such as ponding and pannes. Regarding the ability to migrate inland, many areas have roads and development immediately inland of the marshes which prevent migration, resulting in “coastal squeeze.” We will then discuss possible methods for solving these problems such as finding migration corridors, altering management of Phragmites, building living shorelines, and manipulating sediments by such techniques as thin layer deposition and the creation of runnels.

The ECOS Species Range Project Aquatic Species Distribution Modeling

  • Details: The Environmental Conservation Online System (ECOS) is a web-based information portal used by USFWS to communicate, among other things, species information for federally threatened and endangered species. An important component is the current range map depicting expected occurrence and suitable habitat for a species. Ecological Services in Headquarters with partners, is leading the Species Range Project to help improve, standardize, and streamline species range map delineation using advanced and widely accepted ecological methods, data science, and species distribution modeling (SDM) techniques. Occurrence data points, from USFWS and other data sources, are used in conjunction with appropriate biotic and abiotic covariates to build an inductive model to delineate ranges. The Species Range Project has developed a nationwide species distribution modelling platform specific to aquatic species using a variety of stream network, and both catchment- and watershed-level abiotic landscape metrics. Specifically, we used elevation-based catchment areas from NHDPlus Version 2 to obtain stream and stream network associated environmental covariates, such as mean annual precipitation, Strahler stream order, and flow accumulation. Further, we have incorporated the EPA’s StreamCat dataset to include additional abiotic landscape metrics, totaling 89 possible covariates. Together these are used in the R package BIOMOD to model species current ranges within larger HUC boundaries allowing us to develop aquatics-based species distribution models for any area within the lower 48 states. To date, we have modeled several mussel species, and plan to use the platform for additional aquatic species such as fish and other invertebrate species and are open to running models to assist in other efforts (SSA’s, recovery plans, 5-year reviews, etc.).

The National Wetlands Inventory: Reorganized and Refreshed

  • Details: The National Wetland Inventory Program (NWI) is unique within the USFWS serving as the wetland data steward for the Service as well as serving the wetland data layer on behalf of the Federal Government. In 2019, NWI was reorganized under ES HQ, and for the first time all Regional Wetland Coordinators (except AK) were under one manager. The results have been great and much better than expected with increased efficiency, consistency of messaging and morale, to name a few. The NWI Branch Manager, Jonathan Phinney, and Project Lead, Mitch Bergeson, will reintroduce (or introduce) the revised program providing an overview of the past, present and future of wetland data production, maintenance and usage within the Service and by others. In return, they would appreciate receiving additional usages and needs from the audience with the goal to make the NWI data as relevant and accessible as possible.

The Southeast Aquatic Barrier Prioritization Tool: Assessing Aquatic Fragmentation in the Southeastern United States

  • Details: Fragmentation of river habitats by anthropogenic barriers is one of the primary threats to aquatic species in the United States. In an effort to address this issue, SARP has been working with partners including USFWS to identify, prioritize, and remove barriers to aquatic organisms in the Southeastern United States through the Southeast Aquatic Connectivity Program. SARP has developed a comprehensive living inventory of dams and road stream barriers, detailed metrics to prioritize these barriers for removal or bypass, and has been working with partners within state-based Aquatic Connectivity Teams to incorporate on the ground information and implement high priority barrier removal or remediation projects. Through working with the Conservation Biology Institute and Astute Spruce, SARP’s inventory and prioritization has been optimized and formatted into a user-friendly interactive tool for use by partners. The Southeast Aquatic Barrier Prioritization Tool provides summaries of barrier densities within user specified areas of interest, and allows users to prioritize barriers for removal based on ecological metrics using various filters. The results provided by the tool help identify high priority projects to implement. This tool has allowed SARP’s partners to access information regarding barrier locations and attributes that were not readily accessible in a one stop shop prior to SARP’s work.

The USACE Engineering with Nature Initiative: Lessons Learned, Needs and Opportunities

  • Details: The U.S. Army Corps of Engineers (USACE) Engineering with Nature initiative (EWN) combines research projects, field demonstrations, and communication activities to promote sustainable, resilient infrastructure systems by leveraging natural systems and processes. Unlike built structures using concrete and rebar, natural structures are resilient, adapting to changes in physical, biological, geologic, and chemical processes. The use of nature-based features in engineering design incorporates natural processes into the structure or project design, in order to take advantage of the resilient properties of natural systems. In addition, incorporating these practices reduces maintenance costs while providing ecosystem services. This webinar will provide an overview of the initiative, highlighting lessons learned, needs and opportunities for the future. The presentation will also highlight the publication Engineering With Nature: an Atlas that includes descriptions of 56 projects around the world and provides information on how to nominate potential future projects for Volume 2 of the Atlas to be published in 2020.

Tools and training for assessing road-stream crossings and prioritizing replacements across the Northeast

  • Details: Both a network of partners and a source of shared resources, the North Atlantic Aquatic Connectivity Collaborative (NAACC) offers a collaborative framework for taking on the critical task of assessing and upgrading the hundreds of thousands of outdated road-stream crossings (culverts and bridges) across the Northeast region that represent barriers to wildlife movement and pose flooding risks to communities. The NAACC offers training in standard protocols for conducting assessments, online tools for prioritizing upgrades based on ecological benefits, and a database of road-stream crossings encompassing the 13 Northeast states. This webinar will highlight some of the tools, activities, and accomplishments of the NAACC, and explain how the US Fish and Wildlife Service and our partners are using NAACC tools to assess, prioritize, and upgrade road-stream crossings across the region. For webinar participants working in the Northeast, the webinar will provide an overview of resources that you and your partners can use, contribute to, and advance. For participants working outside the Northeast, the webinar will provide a comparison to the protocols and tools you already have in your region, or give insight into how similar resources could be developed in your area of the country.

U.S. Department of Energy Program and Tools to Support Sustainable Hydropower

  • Details: Over the last decade, the Department of Energy Water Power Technologies Office has supported focused research to provide stakeholders tools and data needed to inform environmental studies and planning for existing and future hydropower development. Specifically, these resources include accurate assessments of the existing hydropower fleet, high-resolution assessments of future power potential from powering existing non-powered infrastructures and new development, as well as the potential environmental impacts and mitigation actions associated with those developments. Tools are available that provide a rapid means to conduct high-level environmental assessments in order to identify the most meaningful environmental issues, as to increase the efficiency of licensing activities. These resources are available through Oak Ridge National Laboratory’s HydroSource web platform and include geovisualization and mapping technologies. This presentation will give an overview of the data and tools, and their utility to environmental assessment.

Using Science, the Water Quality Certification Process, and State Agency Collaboration to Protect Instream Flows

  • Details: Instream flows are water rights that recognize the beneficial uses from keeping some water in the stream and are used to help us manage water. Ecology passed the first Instream Resource Protection Program rule in 1976. Since then we have passed instream flow protection rules in 25 other watersheds in roughly 3 different phases with increasing levels of protections. Instream flows are also developed for hydropower operations as conditions of their 401 Water Quality Certificate (see 33 U.S.C. § 1341). The science used to develop instream flows for hydropower use is similar, but it requires much more collaboration with state and federal agencies, and Tribes, this may include periodic process flows that perform vital stream functions of natural conditions such as sediment transport and channel maintenance. After licensing or re-licensing, the hydroelectric projects are required, through the WQC, to meet instream flow values set for the river system, Water Quality Standards (WQS), and often ESA listed fish obligations. The agencies work collaboratively to provide technical assistance to the hydroelectric stakeholders in meeting WQS the FERC related obligations of fish management.

Validation of USFWS Fish Passage Criteria through Underwater Video

  • Detail: A multitude of technologies currently exist that are employed to aid in our understanding of fish behavior (e.g., radio telemetry), but many are expensive and labor intensive and don’t always provide the level of detail needed to assess fish behavior in and around fish passage structures. For example, how fish behave within a baffled-chute fishway or how downstream migrating fish react to an intake structure. Observing fish in real-time aids in an enhanced understanding of how fish interact with the man-made structures we design for them, and the opportunity is all too often missed. Over the past several years the United States Fish and Wildlife Service (USFWS) Region 5 Fish Passage Engineering Team has collected underwater video, capturing fish behavior at fish passage facilities throughout the East Coast. The results have served multiple purposes—including validating current USFWS Fish Passage Engineering Criteria, highlighting fish passage issues, and serving as a communication tool—and has proven to be a low-cost monitoring tool. The intent of this presentation is to demonstrate how effective underwater video can be when communicating the technical details of a fishway (e.g., importance of weir submergence) with real-time footage of fish behavior. Some of the videos that will be presented include juvenile river herring utilizing an innovative downstream bypass, adult river herring moving through Denil and Steeppass type fishways, behavior of fish at a properly submerged fishway entrance versus one that isn’t, and fish passage issues within an ice harbor and vertical slot fishway. Every underwater video taken has provided one more glimpse into the incredible world of fish passage and will help promote further research as well as guide future fish passage designs.

View, Focus, and Screen Ambient Monitoring Data with the Water Quality Indicators Tool

  • Details: The Water Quality Indicators Project integrates and normalizes available ambient monitoring data to help EPA, state, and tribal staff better identify water quality problem areas. EPA currently publishes information about the health of watersheds based on states’ assessments conducted under the Clean Water Act (CWA 305(b)) program. That data reside in EPA Assessment and Total Maximum Daily Load Tracking and Implementation System and contain information about impaired watersheds (CWA 303(d)). Because a large number of watersheds have not yet been assessed under CWA 305(a), EPA began the WQI project to fill in data gaps. Specifically by using ambient water data in the Water Quality Portal and comparing the WQP data to national or ad hoc water quality criteria (currently only nutrient concentrations). EPA used data analytic methods to stratify the WQP data and is now working to include data visualization tools that will help users display and assess the data. EPA envisions a wide-ranging set of uses for the data, including trend analysis, TDML development and improved state and local permitting and compliance program administration.
