The DNREC Division of Fish and Wildlife conducts juvenile abundance surveys of Atlantic Sturgeon in the Delaware River. This survey monitors population levels and evaluates spawning success rate based on the addition of newly hatched fish entering the sturgeon population. Please report
Delaware River Striped Bass Spawning Stock Survey
The Striped bass, locally known as the Rockfish, is one of the most important fish species along the Atlantic Coast, supporting valuable commercial and recreational fisheries. The DNREC Division of Fish and Wildlife monitors the Delaware River Striped bass population to gather important information that can be used to improve management of the Striped bassCareful Management Ensures the Delaware Bay Remains a Horseshoe Crab Haven
Every spring, millions of living fossils make their way to the beaches along the Delaware Bay, continuing a cycle that’s been underway for thousands of years. Creepy-crawlies more than a foot long clad in carapaces and trailing a tail-like spike emerge from the waves to gather along the shoreline en masse in hopes of finding a mate. These are horseshoe crabs, and the body of water dividing Delaware from New Jersey is home to their largest spawning grounds in the world.Become a Bat Spotter Volunteer
DNREC’s Delaware Bat Program needs dedicated volunteers for the summer field season. Volunteer bat spotters help state biologists collect information about bats and their summer colonies; information needed to determine conservation actions to best protect Delaware’s bats. Volunteers help with several important tasks: Maternity colonyThe Fisheries Section
The DNREC Fisheries Section works to enhance and protect Delaware’s fish and aquatic resources in support of recreational and commercial fishing. It provides first-class fishing and boating access to Delaware’s many waterways. And it conducts fisheries research, resource monitoring and collection of biological information on marine fisheries.Horseshoe Crab Viewing
The Delaware Bay hosts the world’s largest concentration of spawning horseshoe crabs. People come from all over the world to view the spawning crabs and the associated migratory shorebirds. Horseshoe crabs can be viewed on several Delaware Bay beaches and from DNREC’s DuPont Nature Center. When Spawning OccursRecreational Fishing
The DNREC Division of Fish and wildlife provides first-class fishing and boating access to Delaware’s many waterways. Information for Recreational Anglers The Delaware Fishing Report offers information on when to fish, where to fish, which species are biting and how to catch them. It is writtenLicensing and Regulations
Recreational fishing in Delaware requires licenses for most anglers and is governed by both state regulations promulgated by the Department of Natural Resources and Environmental Control, and regional and national regulations. Fisheries Section MenuHorseshoe Crab Monitoring
The horseshoe crab plays a prominent role in the ecology and fisheries of Delaware Bay. The DNREC Division of Fish and Wildlife monitors Delaware’s horseshoe crab population using multiple methods. The crabs are huge feeders on marine worms and bivalves. Their eggs serve as a primary food sourceResearch and Monitoring
Biologists from the DNREC Division of Fish and Wildlife keep track of the state’s fish populations. They work on Delaware’s rivers, ponds, estuaries, on the Delaware Bay and in coastal waters and study how different species are faring. Fisheries Section MenuCommercial Fishing
Commercial fishing in the state of Delaware requires proper licensure and, in some cases, permits. Some fisheries have established quotas. And there are reporting requirements that must be met. Fisheries Section MenuThe American Eel in Delaware
Although many Delawareans may find them unappealing, American Eel (Anguilla rostrata) support a major fishery in Delaware. American Eel (Photo: Duane Raver, Jr.) American Eels are mostly sold live for bait and exported as a food fish. Historically, Delaware landed over 100,000 pounds of eels annually. The eels wereFrom Our Bays to Your Plate: Inside Delaware’s Shellfish Aquaculture Industry
Significant progress in the shellfish industry has been made since the beginning of the 2010s, when Delaware was the only state on the Atlantic coast without shellfish aquaculture. Just a decade later, hundreds of thousands of oysters are being harvested via aquaculture and sold to restaurants and distributors right here in the state.Fish Consumption Advisories
DNREC monitors the presence of chemical contaminants in the edible flesh of finfish and shellfish in Delaware waters. In coordination with the Department of Health and Social Services (DHSS), they issue periodic fish consumption advisories to guide anglers on the amount of fish they can safely consume from specific water bodies to increase risk awareness.Despite Declining Numbers, Hunting Still has Major Benefits for Participants and Delaware
Fifty years ago, roughly 1 in 20 Delawareans hunted, according to license data maintained by the Delaware Department of Natural Resources and Environmental Control. Today, that figure is more like 1 in 50. But that doesn’t mean hunting’s importance has diminished for those who do take part, as the director of the DNREC Division of Fish and Wildlife explains in this piece.Notice of Public Hearing: Revisions to the Boating Regulations
The DNREC Division of Fish and Wildlife will conduct a public hearing to consider comments from the public on proposed revisions to the Boating Regulations.Outreach: Partner and Public Input (Element 7 & 8)
Outreach for the 2025 DEWAP took multiple forms, including formal and informal meetings, workshops, surveys, outreach materials (e.g., presentations, news releases), websites, and social media, as well as personal contacts and correspondence. A dedicated DEWAP website and an email address were established to disseminate information to a wider-audience and receive public input throughout the process.Future DEWAP Review and Revision (Element 6)
The DEWAP will be periodically reviewed and revised according to the development and implementation timeframes of the Department of Natural Resources and Environmental Control – Division of Fish and Wildlife (DNREC DFW) and partners scheduled programs and updates (Element 6). This will be necessary as the monitoring components discussed in this chapter contribute to thePlanning Context
The DEWAP fits into an existing framework of statewide strategies established to conserve and protect the state’s natural resources, including habitat for wildlife. These strategies focus on different approaches to conservation (e.g., land acquisition, preservation, changes in land use, infrastructure investments, policy, etc.), but they are all coordinated and have shared mapping elements and commonDevelopment of Conservation Actions for the 2025 Revision
Conservation actions and research, survey, and monitoring needs were developed for the 2015 DEWAP based on a review of existing conservation and management plans and information provided by DNREC DFW staff and key partners and stakeholders during the DEWAP input process. These conservation programs and plans were identified through a literature search compiling current local,Identifying Issues Affecting Species of Greatest Conservation Need and Key Habitats in Delaware
Conservation issues, including threats or stressors, are human actions that adversely impact wildlife, native plants and natural communities, and the ecological processes that sustain them. Conservation actions are the measures taken to eliminate or minimize these impacts, or to mitigate their effects. While many Conservation Issues had their origins in the 2006 and 2015 DEWAPsHabitat Analysis for the 2025 DEWAP Revision
Habitat Classification The 2025 Wildlife Action Plan generally uses the same wildlife habitat classification scheme as the 2015 Wildlife Action Plan (DNREC DFW 2015). This classification includes all terrestrial and aquatic habitats. Terrestrial habitats and palustrine and estuarine wetland habitats were aligned as closely as possible with NatureServe EcologicalDelaware Hawk Watch
Hawk watch stations are critical in understanding long-term population trends of migratory raptors throughout the country. The DNREC Division of Fish and Wildlife partners with the Delaware Ornithological Society, the DNREC Division of Parks and Recreation and the Delaware Nature Society to operate two hawk watch stations in the state of Delaware.Needs
Need for Information and Planning Although not direct threats, gaps in information and lack of appropriate conservation planning are considered issues that call for important actions to address conservation of SGCN and key habitats. Lack of information on the distribution, status, and ecology of SGCN and key habitats is considered critical becauseClimate Change
Introduction and Regional Perspective Climate change is a major threat to fish and wildlife habitats, populations, and assemblages. Climate change affects ecosystems as distributions of animals and plants change, the timing of natural events is disrupted, and community compositions and structures are altered. Species and populations likely to have greater sensitivities toPollution
Urban wastewater includes stormwater runoff and sewage. Increases in stormwater occur concurrently with high levels of impervious surface and changes in land use associated with development. In older cities, including Wilmington, outdated, combined sewer and stormwater infrastructure can result in sewage flows into streams and rivers, and problems with sewage backup during flooding events. EffortsInvasive and Problematic Species and Diseases
The spread of invasive species poses a significant threat to SGCN throughout the Northeast. With Northeast Association of Fish and Wildlife Agencies (NEAFWA) funding through the Regional Conservation Needs (RCN) Grant Program, Klopfer (2012) identified 238 invasive species from 12 groups with a potential to adversely affect SGCN, while at the same time acknowledging thatNatural system modifications
Natural system modifications are defined as threats from actions that convert or degrade habitat in service of “managing” natural systems, often to improve human welfare (Salafsky et al. 2008). Fire Suppression One example of a natural system modification is the suppression of fire. Natural, lightning-causedBiological Resource Use
Hunting & collecting terrestrial animals This category includes threats from the consumptive use of biological resources, including deliberate and unintentional harvesting, as well as the persecution or control of specific species (Salafsky et al. 2008). This threat has been identified as an issue for many amphibian and reptile SGCN primarily due toTransportation-related Issues & Human Disturbance
Roads and other transportation corridors have profound effects on wildlife populations. They represent major sources of pollutant load, and they can be barriers to dispersal for many species, fragmenting habitat and leading to genetic isolation of local populations. The ecological effects of roads are described in several reviews (Trombulak and Frissell 2000), including some focusedEnergy Production

The port complex of the Delaware River and Bay is the second largestAgriculture
Agriculture is an important part of Delaware’s history, culture and economy. Many Delaware farmers utilize Best Management Practices (BMPs) and are enrolled in Natural Resources Conservation Service (NRCS), Department of Agriculture (USDA), or U.S. Fish and Wildlife Service (USFWS) cost share programs that are environmentally friendly and minimize impacts to wildlife. Some agricultural practices, however,Residential and Commercial Development
Most Delaware SGCN depend, to some extent, on lands facing habitat loss and fragmentation from residential and commercial development. Delaware’s human population is predicted to increase by about 100,000 people between 2025 and 2050, resulting in increases in land development statewide (Delaware OSPC 2025). Land Development in theConservation Opportunity Areas
Guiding Conservation on the Ground in Delaware A goal of SWAPs is the development of COAs that map and prioritize opportunities for conservation of key habitats and SGCN. AFWA Best Practices (2012) recommend that WAPs identify and spatially depict priority areas on the landscape that offer the best opportunities and potential forStatewide Conservation Actions
In the process of identifying conservation actions for SGCN and their habitats, recurring patterns and priorities emerged that cross between taxonomic and ecological boundaries. These more general, statewide conservation actions were recognized to have broad impacts across taxa and habitats. These broader conservation actions address the primary statewide issues identified in Threats to SGCN andPlants

Invertebrate Diversity of Delaware Invertebrates account for an exceptionally large proportion of the biodiversity of Delaware. In Pennsylvania, where invertebrate species numbers have been quantified, Rawlins and Bier estimate that invertebrates make up 53.2% of the state’s species diversity, with plants, algae, fungi, and lichens accounting for 40%, and vertebrate animals onlyFish

Important groups for which Delaware has particularly high regional responsibility include neotropical migrant songbirds that use the state for stopover habitat, migrating and wintering raptors,Conservation Actions
Addressing Threats through Conservation Actions Conservation Actions are the measures taken to eliminate, minimize, or mitigate the impacts of the issues facing Delaware’s Species of Greatest Conservation Need (SGCN) and their habitats. This chapter addresses Element 4 and presents the actions the Delaware Department of Natural Resources and Environmental Control, Division ofThreats to SGCN and Habitats
Introduction Delaware’s Species of Greatest Conservation Need (SGCN) and their habitats face numerous issues that may adversely affect them and compromise their status in the state. Some issues are global or national in scale, while others may be regional, statewide, or local.
