Problem - Urbanization of the 150-square-mile Irondequoit Creek basin in Monroe and Ontario Counties, N.Y., continues to spread southward and eastward from the City of Rochester. Conversion of forested land to other uses over the past 40 years has increased to the extent that more than 50 percent of the basin is now developed. This expansion has increased flooding and impaired stream-water quality in the northern (downstream) half of the basin. A precipitation-runoff model of the Irondequoit Creek basin could be used as a management tool by water-resources managers to better understand the hydrology of the basin, permit simulation of planned or hypothetical land-use changes, evaluate the adverse effects of future...

Problem - A variety of factors potentially impact natural resources in the Neversink River basin and in other tributaries to the Upper Delaware River along the New York, Pennsylvania, and New Jersey boarders in the northeastern US. Increased urbanization within most watersheds of the Delaware River has decreased forested lands and ground permeability; fractionated forests, streams, and rivers; impounded flowing waters, and discharged municipal, agricultural, and industrial pollutants into many waterways. The effects on water quality and hydrology have been quantified relatively well. The direct impacts of these perturbations on biological components of stream and river ecosystems are sometimes known, however, more...

Abstract: We present an inverse modeling approach for reconstructing the effective thermal conductivity of snow on a daily basis using air temperature, ground temperature and snow depth measurements. The method is applied to four sites in Alaska. To validate the method we used measured snow densities and snow water equivalents. The modeled thermal conductivities of snow for the two interior Alaska sites have relatively low values and reach their maximum near the end of the snow season, while the conductivities at the two sites on the Alaskan North Slope are higher and reach their maximum earlier in the snow season. We show that the reconstructed daily thermal conductivities allow for more accurate modeling of ground...

This data release documents streambed sediment thickness in the Neversink watershed (NY) as determined by field observations and HVSR passive seismic measurements, and were collected as an extension of a previous data set collected in the same watershed (see Associated Items). These measurements were made between May 17, 2021 and May 21, 2021 using MOHO Tromino three-component seismometers (MOHO, S.R.L.). Seismic observations were converted to sediment thickness (depth to bedrock, meters) using the horizontal-to-vertical spectral ratio (HVSR) method. Resonance frequencies were determined from time domain data using GRILLA (MOHO, S.R.L.) software and converted to inferred depth to bedrock for a range of possible...

The growth of temperate forests is typically limited by the availability of nitrogen. Elevated concentrations of nitrate in some Catskill Mountain streams, which are tributary to New York City's water-supply reservoirs west of the Hudson River, indicate that the forests of this region are at the early stages of nitrogen saturation. That is, nitrogen is available in excess of the amount utilized by vegetation and soil microorganisms in the forests. Nitrogen saturation is a concern because the mobile nitrate that moves through soil is accompanied by other nutrients such as the base cations calcium and magnesium that are necessary for forest growth but are present in short supply in some Catskill soils. And, nutrient...
Background With few exceptions, the contemporary and past effects of acidification on fish populations and communities in streams across acid-sensitive regions of NY have not been documented. The pervasive lack of information only permits anecdotal insight into the spatial effects of acidification on stream-fish assemblages and essentially precludes any broad effort to quantify temporal trends and potential recovery of fish assemblages in less acidic or less toxic streams. Though the effects of acidification on fish assemblages have been qualified in several streams of the eastern Adirondacks during 1979, the 1980s, and early 2000s, (Schofield and Driscoll 1987; Simonin et al. 2005) quantitative impacts were...

The Ellison Park wetland, a 423-acre, predominantly cattail marsh at the mouth of Irondequoit Creek in Monroe County near Rochester, N.Y., was evaluated for its potential role to decrease phosphorus loads that are derived from a 151-square-mile largely urbanized area and that ultimately enter and exacerbate efforts to ameliorate the eutrophic conditions in Irondequoit Bay. Monroe County's water-quality management plan included (1) modification of flow patterns upstream from and within the wetland by diverting storm runoff into backwater areas of the wetland, and (2) construction of a flow-control structure midway through the wetland that would cause short-term rises in water levels and increased dispersion of...

Problem The Town of Riverhead in the northeastern Suffolk County includes rural farmland and suburbs and is bounded by the Long Island Sound to the north and Peconic Bay to the southeast. Riverhead’s close proximity to saline embayments and its location along the northeastern discharge area for Long Island’s groundwater flow system makes it vulnerable to saltwater intrusion. Several public-supply wells in Riverhead have experienced increased chloride concentrations recently due to the encroachment of saltwater. Riverhead is underlain by a sequence of unconsolidated deposits ranging in age from Pleistocene to Upper Cretaceous that overlie a basement complex of Precambrian bedrock. These deposits are part of Long...

The region within the Gulf Coast Prairie Landscape Conservation Cooperative (Gulf Coast Prairie LCC) faces many challenges that threaten both wildlife and their habitat within this diverse landscape. The once extensive grassland system has been impacted by urban and agricultural development. Large river systems struggle to maintain watershed integrity and base flows. Coastal systems fight the effects of reduced freshwater inflows. Other threats, such as climate change, pollution, invasive species and disease, also put a strain on native species and habitats.

The four primary objectives of this project were to: (1) compile a dataset of fish occurrence records for the entirety of the Rio Grande drainage in the US and Mexico; (2) improve that dataset by reformatting dates, synonymizing species names to a modern taxonomy, georeferencing localities, and flagging geographic outliers; (3) for those species with sufficient data for modeling, create species distribution models (SDMs); (4) use the environmental conditions determined via those models to project the species distributions into the future under two climate scenarios. To accomplish those objectives, we compiled 495,101 fish occurrence records mined from 122 original sources into a single database. We then, on the...

Executive Summary: We provide an analysis of Sonoran Desert water network connectivity to inform managers of current conditions for target wildlife and how the connectivity will change as the landscape becomes more water limited.Climate change is expected to lead to fragmentation of the network, increasing coalescence distance by 8% and reducing the persistence and overall number of waters on the landscape. Identification of key water sites, ranked by network connectivity metrics, are presented in Appendix B. Wetland number under our scenario of water limitation will decline by 43% reducing network resilience.Anurans and Caudates, although varying in ability to disperse, generally experienced reduced connectivity...

In partnership with South Atlantic Landscape Conservation Cooperative members, we assessed current and projected connectivity for three species that inhabit bottomland hardwoods throughout the southeastern US: black bear (Ursus americanus), Rafinesque’s big-eared bat (Corynorhinus rafinesquii), and timber rattlesnake (Crotalus horridus). For each species, we mapped important habitat connections between core patches of habitat using three different modeling approaches (Connectivity Analysis Toolkit (CAT), Circuitscape, and Linkage Mapper) that incorporated three types of resistance layers (expert opinion, niche modeling, and empirical data for the black bear only). The result was 21 sets of important connections,...

The 2014 annual total precipitation and the current 30-year climatic normal (based on 1981–2010) are also shown by regional planning area.
Executive summary: The avifauna within the Sky Islands of southeastern Arizona includes species found nowhere else in the U.S. Thus, birdwatchers from across the globe visit the region, providing a vibrant state and local ecotourism industry. RMRS scientists initiated a study in the 1990s on avian distribution and habitat associations within the Sky Islands. Since then, the region has been under increased stress from ongoing droughts and wildfires, likely associated with climate change. By re-measuring vegetation and bird populations in 2014 following wildfires and applying climate change models, we will assess the singular and synergistic effects of climate change and wildfire and provide strategies for managing...

Freshwater fishes are globally among the most imperiled major biodiversity groups and they are especially endangered in the North American deserts of the vast binational Desert LCC. Sixty seven native fish species of conservation concern are in the study area, which includes all of the DLCC in both the US and Mexico. Essentially all species in our study area are understudied and management of them has been greatly impeded by the intrinsic difficulties of working internationally and by relative lack of, or inaccessibility to, basic knowledge about their distributions and conservation status. We propose to mine data from all online and known US-based institutions holding specimen-based occurrence records from our...

The North Atlantic Landscape Conservation Cooperative provides a partnership in which the private, state, tribal and federal conservation community works together to address increasing land use pressures and widespread resource threats and uncertainties amplified by a rapidly changing climate. The partners and partnerships in the cooperative address these regional threats and uncertainties by agreeing on common goals for land, water, fish, wildlife, plant and cultural resources and jointly developing the scientific information and tools needed to prioritize and guide more effective conservation actions by partners toward those goals.
BACKGROUND The Adirondack region of New York has a history of relatively high atmospheric sulfur (S) and nitrogen (N) deposition (Greaver et al. 2012). Adirondack ecosystems have been impacted by these inputs, including soil and surface water acidification, and impaired health and diversity of forest vegetation and aquatic biota. Air quality management, through the Clean Air Act, the U.S. Environmental Protection Agency NOx Budget Trading Program, and the Clean Air Interstate Rule (CAIR) has resulted in decreases in atmospheric S and N deposition in the Adirondacks and throughout the eastern U.S. (Lehmann et al., 2005), which is driving the recovery of surface waters from past acidification. Section 303(d)...
The overall goal of this project has been the development of forest health and sensitivity indicators and “1st-generation” maps of potential sensitivity to disturbance for lands within watersheds of the NYC water supply in the Catskill Mountains of New York. The methodologies and data layers created in this effort can now be used to aid management decisions and help determine the extent and magnitude of terrestrial and aquatic responses to acidic deposition. The data products derived from this effort have been produced and documented in such a manner that stakeholders can now use these products for site evaluation as well as to perform more extensive analysis on the suite of readily available GIS and image-based...
