Habitat use, diet, prey availability and foraging ecology of the endangered Hawaiian hoary bat (Lasiurus cinereus semotus, Vespertilionidae), was examined in the east Maui region inclusive of the Waihou Mitigation Area, Pu‘u Makua Restoration Area and the wind power facility operated by Auwahi Wind Energy, LLC. The study was conducted to inform the mitigation and management requirements of Auwahi Wind Energy, research funding was provided by Auwahi Wind Energy, LLC (Auwahi Wind) to fulfill requirements for mitigating bat fatalities under its approved incidental take permit. Acoustic monitoring over the three-year period demonstrated that bats are present and actively feed year-round at the Waihou Mitigation Area....
This map service layer provides information for projects funded by the 20 regional fish habitat partnerships through the National Fish Habitat funds. Projects funded since 2006 are represented in the service layer and the data are expected to be updated annually. Projects in the database range from on-the-ground restoration, partnership coordination, outreach and education events, and species distribution and habitat assessments.

Herbicide treatments were applied to Zerene silverspot (Speyeria = Argynnis zerene zerene) post-diapause larvae and early blue violets (Viola adunca), the larval host plant of the Zerene silverspot butterfly, in two greenhouse experiments in 2018-2019. Treatments included distilled water for untreated (U), Agri-Dex (A), Nu Film IR (N), clopyralid (C), clopyralid with Agri-Dex (CA), clopyralid with Nu Film IR (CN), fluazifop-p-butyl (F), fluazifop-p-butyl with Agri-Dex (FA), and fluazifop-p-butyl with Nu Film IR (FN). Zerene silverspot responses measured in the 2018 experiment included larval and pupal survival, sex ratio, larval and pupal development time, pupal and adult mass, adult morphology, female fecundity,...

The Midwest Glacial Lakes Partnership is proud to share this Shoreline Living booklet, which provides examples of everyday shoreline property owners that dipped their toes into a natural shoreline.
This map service layer provides information for projects that were supported by at least one of the 20 regional fish habitat partnerships but did not leverage National Fish Habitat funds. This service layer is a work in progress and only represents those projects shared by fish habitat partners. A more complete representation of supported projects is in progress. Currently this service layer will be updated as new information becomes available, but as this service layer matures it is expected to be updated annually. Projects in the database range from on-the-ground restoration, partnership coordination, outreach and education events, and species distribution and habitat assessments.
In 1998, the Quaker Neck Dam was removed from the Neuse River near Goldsboro, North Carolina, restoring access to more than 120 km of potential main-stem spawning habitat and 1,488 km of potential tributary spawning habitat to anadromous fishes. We used plankton sampling and standardized electrofishing to examine the extent to which anadromous fishes utilized this restored spawning habitat in 2003 and 2004. Evidence of spawning activity was detected upstream of the former dam site for three anadromous species: American shad Alosa sapidissima, hickory shad A. mediocris, and striped bass Morone saxatilis. The percentages of eggs and larvae collected in the restored upstream habitat were greater in 2003, when spring...
The Prioritization Tool is a web application for identifying the best opportunities to restore rare and threatened habitats for Species of Greatest Conservation Need (SGCN) and other species in the Northeast. The goal underlying the development of the restoration tool was to identify areas of degraded habitat having high restoration potential, which if restored would contribute to the network of connected, intact, and resilient sites for biodiversity conservation mapped by Nature’s Network. The tool allows users to (1) display a series of prioritization maps developed for a set of pre-defined “scenarios” (e.g., American woodcock), and (2) create their own scenarios using a catalog of nearly 400 metrics.The basic...

Many of the world’s large river systems have been greatly altered in the past century due to river regulation, agriculture, and invasion of introduced Tamarix spp. (saltcedar, tamarisk). These riverine ecosystems are known to provide important habitat for avian communities, but information on responses of birds to differing levels of Tamarix is not known. Past research on birds along the Colorado River has shown that avian abundance in general is greater in native than in non-native habitat. In this article, we address habitat restoration on the lower Colorado River by comparing abundance and diversity of avian communities at a matrix of different amounts of native and non-native habitats at National Wildlife...
Habitat fragmentation is an important cause of biodiversity loss in freshwater systems, as worldwide rivers have been fragmented by dams and other hydraulic structures. To restore freshwater fish populations, some barriers have been removed, but the long-term ecological effects of this removal have been rarely quantified. In the present study, we quantified the effects of barrier removal on river colonization by anadromous sea lamprey (Petromyzon marinus) by analyzing the spatial distribution and nest density in a small coastal river (France) from 1994 to 2011. Our results demonstrated the benefit of dam removal within few years after restoration. Indeed, the spatial distribution of nests shifted significantly upstream...

The U.S. Geological Survey, in cooperation with the City of South Padre Island, Texas, collected baseline seagrass, benthic invertebrate, and water-quality data for a near-shore area of the Laguna Madre near South Padre Island in July 2021. Sample and data collection points were located within a grid consisting of eight transects and three sampling points on each transect. The data included in this data release are presented in a comma-separated values (csv) file format.
