The Humboldt Bay-Eel River region may experience the highest rate of relative sea level rise increase along the West Coast. The Project will engage stakeholders to discuss community and science needs for planning and implementing adaptation measures to sea level rise. The Project is a critical step in developing an ecosystem based-management (EBM) approach to guide the protection, management, enhancement, adaptation, restoration, and possible redistribution of Humboldt Bay-Eel River Delta habitats under future climate scenarios. This process will be informed by the best-available science, the needs of Humboldt Bay-Eel River Delta agricultural producers, and other community members.

To better understand the impacts of climate change, ecological studies are increasingly addressing the different effects of temperature on organisms and ecosystems. To measure air temperature at biologically relevant scales in the field, ecologists often use small, portable temperature sensors. These sensors must be shielded from solar radiation to provide accurate temperature measurements, but a review of 18 years of ecological literature indicated that shielding practices vary across studies (when the shielding is reported at all), and that ecologists often invent and construct ad-hoc radiation shields without testing their efficacy. The project researchers performed two field experiments to examine the accuracy...

California’s Central Valley is a nexus for water resources in the state, draining the Sacramento and San Joaquin River watersheds. Urban centers, agricultural operations, and the environment all compete for limited water, and demand is expected to only increase as the population grows and agriculture intensifies. At the same time, the water supply is projected to decrease as temperatures rise, precipitation patterns change, and the frequency of extreme droughts increases. The Central Valley also provides critical wetland habitats to migratory waterbirds, and wetland managers require information on how to best use water resources to support wildlife objectives, particularly during drought. This project seeks to...
An urgent need exists to uniformly assess river corridors, including floodplains, and to prioritize areas for protection across the North Atlantic landscape. These are daunting tasks since there are no well-defined methods to delineate and assess scores of diverse river corridors in this region. The RiverSmart research group at UMass Amherst has made meaningful strides toward a uniform assessment of North Atlantic river corridors having assembled a task force of river specialists, analyzed ecologic and geomorphic threats, scrutinized the wide-ranging approaches to assess riparian habitats, and performed initial evaluations in diverse watersheds. In this project, we will build on this base. During the first year,...

Habitat fragmentation is considered to be a leading cause that is responsible for the long-term population declines of Northern Bobwhites. There are numerous factors responsible for habitat fragmentation such as expanding suburbanization, intensification of agricultural and forestry practices, and invasions of exotic plants; the unifying theme is how people use land for settlement and the production of food and fiber. As patches of habitat become smaller and more isolated, populations experience a lower probability of persistence that results in local extinctions, which can lead to larger, and perhaps even regional extinctions. However, we lack a strong empirical and quantified basis that describes the numerical...

The Sicklefin Chub (Macrhybopsis meeki) requires main channel gravel and sand runs in turbid flowing waters; however, decreased and controlled flows from dam operations have resulted in excessive siltation of these key gravel beds. Dams also reduce turbidity and alter water temperatures, making the habitat unsuitable for this species.

The Lahontan Cutthroat Trout (Oncorhynchus clarki henshawi) is native to the Lahontan basin of northern Nevada, northeastern California, and southeastern Oregon. Like other native trout species, the Lahontan Cutthroat Trout is found in a wide variety of cold-water habitats including large terminal alkaline lakes, alpine lakes, slow meandering rivers, montane rivers, and small headwater tributary streams. They currently occupy only about 10 percent of their historic range primarily due to habitat fragmentation from dams and water diversions, changes in water flow patterns, loss of riparian and aquatic habitat quality, severe drought conditions, and the introduction of non-native trout species. One population in Walker...

The agricultural areas of the Mountain States have created a substantial drain on the water resources of this region. Northern Montana stands out as an area of very high risk for fish habitat degradation on the few streams and rivers in the area. This threatened area is principally comprised of row crops, such as wheat, barley, and alfalfa production, and cattle farms. Other areas of high risk of habitat degradation, such as southern Idaho and northeastern Colorado, correspond to areas with a high density of row crops, typically corn and wheat, cattle farms, alfalfa and potato (particularly in Idaho) production, and rangeland. Farms and ranches dependent on irrigation require large amounts of water diverted from...

The Sonoran Desert is the only place in the world where Saguaro cacti grow. It can take up to 100 years for a Saguaro cactus to grow an arm in areas of low precipitation. The Sonoran Desert receives more rainfall than any other desert, which is approximately 10 inches (25 centimeters) a year on average. In the 1800s, many people used the Gila River as a trail across Arizona. This trail became known as the Gila Trail. Arizona is large enough to fit all of New England plus the State of Pennsylvania inside of it. Arizona is the only State besides Hawai'i that does not observe Daylight Savings time. Santa Fe, New Mexico, is the highest capital city in the United States at almost 7,200 feet (2,286 meters) above sea level....

There are three designated megaregions in the Pacific Coast States: Southern California, with a population of 22.4 million; Northern California, with a population of 14.6 million; and Cascadia (from Vancouver, British Columbia to Eugene, Oregon), with a population of 8.4 million. These areas have enormous effects on both the inland and coastal aquatic habitats. Continual development increases areas of impervious surfaces (completely altering natural water flows and hydrology) and the amount of sewage discharge, sediments, and other pollutants associated with urbanization. Ever increasing urban water needs can be far reaching and affect systems and fish habitat far away from the urban areas. Los Angeles, which is...
The Columbia River historically supported one of the greatest salmon and steelhead runs on Earth. Prior to the 1840s, up to 16 million salmon and steelhead returned to the Columbia River to spawn each year. Unfortunately, by the end of the 20th century that number declined to less than 1 million fish annually. In response to the severe population declines of Columbia River salmon by the 1990s, as the result of habitat degradation in the basin, the National Marine Fisheries Service (NMFS) designated 13 stocks of anadromous salmonids as Federally threatened or endangered with extinction under the Endangered Species Act (ESA). There are currently 28 listed stocks of salmon and steelhead, plus an additional three more...
