Texas has flown flags for six different nations, which complicates fisheries management in this region. Spain 1519-1685 France 1685-1690 Spain 1690-1821 Mexico 1821-1836 Republic of Texas 1836-1845 United States 1845-1861 Confederate States 1861-1865 United States 1865 to present More land is farmed in Texas than in any other State. Texas has 624 miles (1,024 kilometers) of coastline along the Gulf of Mexico. The Trinity River is 710 miles (1,140 kilometers) long and is the longest river that flows entirely within the State of Texas. Original Federal plans called for building 36 locks and dams from Trinity Bay near Houston to Dallas but only 7 were built. The Brazos River is translated as "The River of the Arms...

Partnership - Matanuska-Susitna Basin Salmon Habitat Partnership Alexander Creek Watershed, a tributary of the Susitna River, was formerly a significant sport fishing area covering hundreds of square miles in the Matanuska-Susitna Borough. In the late 1990s, this system was considered to be a highly productive Chinook and Coho Salmon habitat, and, arguably, the premier Chinook Salmon sport fishing area in the Matanuska-Susitna Valley. Today, however, due to low returns, the Alexander Creek drainage is closed to Chinook Salmon harvest, and Alexander Creek Chinook Salmon are considered a stock of concern by the Alaska Department of Fish and Game. This decline is largely due to the introduction of Northern Pike (...

Tribal communities’ traditions, identities, and economies rely heavily on local natural resources, making tribes especially vulnerable to climate change impacts, including changes in seasonal patterns and the potential loss of culturally and economically important species. The goal of this project was to build tribal capacity in the Pacific Northwest to successfully plan for and adapt to the effects of climate change. The funds associated with this project supported the Affiliated Tribes of Northwest Indians (ATNI) Tribal Leaders Summit on Climate Change held on March 10-11, 2015 in Portland, Oregon. The summit gathered tribal leaders to discuss climate change impacts; share tribal strategies, plans, and policies;...

In order for science to have the most impact on resource management, it needs to directly address the questions that managers and other stakeholders have. Essentially, the ways in which researchers and resource managers collaborate can affect the use of scientific information in decision-making. Previous research has shown that relatively more collaboration between researchers and resource managers (or even the general public) tends to lead to more and more effective use of new scientific information. However, we do not yet have good ways to evaluate these research processes or the outcomes we expect them to produce. This project will assess the key variables necessary for the successful production of usable climate...

This project identifies opportunities to manage flows, connections, and landscapes to increase the resilience of human communities and ecosystems. This research identifies dynamic and adaptive solutions to managing river flows that allow continued provision of valuable infrastructure services such as flood control, hydropower, and water supply, while also supporting thriving river ecosystems - both today and into the future. The goals of the research were to: 1) Evaluate the potential impacts of climate change on hydrologic regimes, 2) Determine the flow regime changes that will be required to provide riverine environmental services and any risk associated with these changes, and 3) Explore management alternatives...

We propose to empirically characterize hydrology/fish-production relationships for different ecological groups of fishes living in the Red River and associated reservoir habitats by: 1. Correlating historic hydrologic data with catch curve residuals, and 2. Annual growth rate estimates of fish collected from the Red River and associated reservoirs. The catch curve residual approach for indexing year class strength has been validated and successfully used to quantify the relationship between reservoir hydrology and YOY recruitment for white crappie and largemouth. The essence of the approach is as follows. Catch curves (a correlation between the natural log of fish abundance and age) are used to measure total instantaneous...

Ecosystem services provided by floodplains include removal of nitrogen, phosphorus, and sediments, and sequestration of carbon. Effectiveness of floodplains in providing these services is dependent on the extent and location of connection between floodplain and river. Tributary loading of sediments, nitrogen and phosphorus to the Upper Mississippi River contribute to the development of river and coastal eutrophication as well as hypoxic conditions in the Gulf of Mexico. Recent research has shown that management of river connectivity of channels to floodplains is an effective mitigation strategy to remove nutrients, sediment, and carbon from river flows. The confluence of the Maquoketa and Mississippi Rivers is a...

The project will use baseline data on pre-restoration measures of baseline hydrology and water quality to evaluate the impacts of large scale wetland and prairire restorations on hydrology and water quality including: recovery of key habitats and functions; abilities of wetlands to buffer variable water flows; ability of groundwater to buffer water flows; groundwater and surface water quality; changes in groundwater movement; rates of denitrification and carbon storage/ transport.

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...

In the western U.S., rising temperatures and pronounced drought conditions pose significant challenges to public land managers. Widespread declines of multiple plant species have already been observed, providing insight into what the future could look like for vegetation in the region as conditions are projected to become warmer and drier. To understand how vulnerable western ecosystems are to drought, managers need to know which climatic and soil conditions cause habitats to change, and at what rate these changes may occur – important topics on which there is little available data. This project seeks to identify the vulnerability of habitats in the western U.S. to drought. Researchers will compare changes in...

Maple syrup is produced from the sap of sugar maple trees collected in the late winter and early spring. Native American tribes have collected and boiled down sap for centuries, and the tapping of maple trees is a cultural touchstone for many people in the Northeast and Midwest. Overall demand for maple syrup has been rapidly rising as more people appreciate this natural sweetener. Yet because the tapping season is dependent on weather conditions, there is concern about the sustainability of maple sugaring as the region’s climate changes. The distribution of sugar maple could move north into Canada and the sap flow season may become shorter in the future. Not only could these changes affect producers and consumers...
