Endangered Animals in New Hampshire: Species, Laws, and What You Need to Know
May 13, 2026
New Hampshire may be one of the smallest states in the country, but its forests, wetlands, rivers, and coastal habitats support a surprisingly wide range of wildlife — including dozens of species on the brink of disappearing. Almost 50 native species are considered threatened or endangered in the state. Some of these animals are well-known; others are rarely seen by the public.
Whether you’re a hiker, a landowner, a developer, or simply someone who cares about the Granite State’s natural heritage, understanding which animals are protected — and what the law requires of you — matters more than you might think. This guide walks you through the endangered animals in New Hampshire, the legal framework that protects them, and exactly what you can and cannot do when you encounter one.
Key Insight: Ignorance of endangered species law is not a legal defense. Both state and federal protections apply in New Hampshire, and violations can result in serious penalties.
How Endangered Species Are Listed and Protected in New Hampshire
In New Hampshire, a species can be protected at two levels: state and federal. Each system has its own listing criteria, enforcement authority, and legal consequences. Endangered species policy in New Hampshire involves the identification and protection of endangered and threatened animal and plant species, with policies implemented and enforced by both the state and federal governments.
At the state level, the foundation is the New Hampshire Endangered Species Conservation Act. The New Hampshire Endangered Species Conservation Act (1975) mandated that state officials develop and maintain a list of the state’s endangered and threatened species. New Hampshire Fish and Game is responsible for administering the New Hampshire Endangered Species Conservation Act.
Endangered wildlife are those native species whose prospects for survival in New Hampshire are in danger because of a loss or change in habitat, over-exploitation, predation, competition, disease, disturbance or contamination. Threatened wildlife are those species which may become endangered if conditions surrounding them begin, or continue, to decline. Wildlife species of Special Concern are those species of wildlife that either could become Threatened in the foreseeable future or were recently delisted from the NH Endangered and Threatened species.
At the federal level, the Endangered Species Act of 1973 (ESA) provides the overarching framework. The federal Endangered Species Act (ESA) of 1973 provides for the identification, listing, and protection of both threatened and endangered species and their habitats. It prescribes a process known as “listing” for a species to become formally recognized as endangered or threatened, and thereby given protections under the ESA.
NH Fish and Game’s Nongame and Endangered Wildlife Program, established in 1988, is the steward for the state’s nongame wildlife — species not hunted, fished, or trapped. Through wildlife monitoring and management, plus outreach and education, the Nongame Program works to protect over 400 species of mammals, birds, reptiles, and amphibians, as well as thousands of insects and other invertebrates.
Pro Tip: The NH Fish and Game Department maintains a printable list of all endangered and threatened wildlife species in the state. Consulting it before starting any land-disturbing project can help you avoid costly legal issues.
Federally Listed vs. State-Listed Endangered Animals in New Hampshire
One of the most important distinctions to understand is that a species can be state-listed, federally listed, or both — and each classification carries different legal implications. Being listed under one system does not automatically mean a species is listed under the other.
- Federally listed species are protected everywhere in the U.S. under the ESA, regardless of state borders.
- State-listed species are protected within New Hampshire under the state Endangered Species Conservation Act.
- Some species appear on both lists, giving them dual-layer protection.
As of July 2016, New Hampshire was home to 10 species — six endangered species and four threatened species — listed under the federal Endangered Species Act (ESA). Of these, seven were animal species and three were plant species. The state list is broader, reflecting species that may be rare in New Hampshire specifically even if they are more common elsewhere.
The agencies administering each list are also different. The U.S. Fish and Wildlife Service (USFWS) and National Oceanic and Atmospheric Administration (NOAA) Fisheries administer the ESA. Broadly speaking, USFWS has jurisdiction over listed terrestrial and freshwater species and NOAA has jurisdiction over marine species.
| Feature | State-Listed (NH) | Federally Listed (ESA) |
|---|---|---|
| Governing Law | NH Endangered Species Conservation Act (RSA 212-A) | Endangered Species Act of 1973 |
| Administering Agency | NH Fish and Game Department | USFWS / NOAA Fisheries |
| Geographic Scope | New Hampshire only | Entire United States |
| Penalty for Violation | Misdemeanor under state law | Up to $25,000 per violation (civil); criminal penalties also possible |
| Habitat Protection | Limited | Critical habitat designation possible |
You should also be aware that the ESA only protects species that are likely to go extinct in the foreseeable future, meaning that many species whose numbers are declining do not qualify for the protections of the ESA. This is why the state list often includes species that aren’t yet on the federal radar — and why both lists matter.
Notable Endangered Animals Found in New Hampshire
New Hampshire’s varied landscapes — from its White Mountain forests to its short Atlantic coastline — support a wide variety of at-risk species. Here are some of the most notable endangered animals you might encounter in the state, along with what makes each one so vulnerable. You can also learn about some of the dangerous animals in New Hampshire that share these same habitats.
Piping Plover
The piping plover nests on sandy beaches, and New Hampshire’s short coastline makes each nesting attempt especially important, with intensive monitoring and protection. This small shorebird is both state- and federally listed, and its nesting sites along New Hampshire’s beaches are actively managed each season.
Timber Rattlesnake
The timber rattlesnake — often thought of as a southern species — still persists in New Hampshire, where it is state-endangered and living near the northern edge of its range in New England. It occurs in very limited, sensitive sites and is long-lived and slow to reproduce, making populations vulnerable to disturbance and persecution.
Little Brown Bat
The little brown bat (Myotis lucifugus) has severely declined in the Northeast due to white-nose syndrome. Once one of the most common bats, cave-hibernating colonies have experienced major losses, affecting insect control and ecosystem function. This species is a stark example of how disease can devastate wildlife populations with alarming speed.
New England Cottontail
The New England cottontail (Sylvilagus transitionalis) is the only rabbit native to the New England region. It is active in both daylight and nighttime hours. Once widespread, they are now endangered. New Hampshire and other New England states have started habitat plans to encourage landowners to create rabbit-friendly habitats for cottontails. The Great Thicket National Wildlife Refuge is a conservation area that protects New England cottontails and other species.
Bald Eagle
Bald eagles are listed as endangered in New Hampshire and threatened in the United States. This species is recovering from effects from widespread use of pesticides in the past. They can often be seen during migrations and during winter, when they hunt on Great Bay. Bald eagles are opportunistic feeders, sometimes hunting fish or water birds, but also taking advantage of the carcasses of large animals, such as deer.
Brook Floater Mussel
The brook floater mussel is currently listed as an endangered species in New Hampshire and most New England states. It is losing habitat as greater loads of sediment and pollutants reach the river and as water temperatures rise. It’s a reminder that endangered animals aren’t always large or charismatic — some of the most ecologically significant species are easy to overlook.
Pied-Billed Grebe
The pied-billed grebe is listed as endangered in New Hampshire. Its nests are located in vegetation just above the surface of water, often in the impoundments of beaver or man-made dams. If water levels rise or fall significantly during the nesting season, the nests can fail due to flooding or stranding. In addition, the loss and degradation of wetlands in most of New England make the species particularly vulnerable to decline.
Sedge Wren
The sedge wren is listed as endangered in New Hampshire and much of New England. This bird species has experienced a severe decline in population throughout much of the Northeast, largely due to the extensive draining and filling of wetlands, ditching of salt marshes, and the resultant spread of common reed (Phragmites australis), a non-native grass of little value to native wildlife.
Canada Lynx
The Canada lynx is a shy, secretive forest dweller that mostly hunts snowshoe hares. It is about the size of a bobcat but with longer hair. It was once common to the northeastern states. In recent years, Canada lynx have been spotted in the northern borders of Vermont and New Hampshire. It remains federally threatened across its U.S. range.
Important Note: New Hampshire’s endangered insect species also deserve attention. The monarch butterfly, white mountain fritillary, and frosted elfin butterfly are all native to the state and all three are endangered. Other native insects include the yellow-banded bumblebee, Puritan tiger beetle, and Appalachian tiger beetle — they are all endangered.
What You Cannot Do Around Endangered Animals in New Hampshire
Both state and federal law place strict limits on human interaction with endangered species. Understanding these restrictions is essential — whether you’re out on a nature walk, managing a construction project, or simply a property owner.
Under the federal ESA, the core prohibition is on “taking” a listed species. It is illegal to “take” a listed species, meaning a person or company cannot “harass, harm, pursue, hunt, shoot, wound, kill, trap, capture, or collect” any individual of a listed species without a permit. It is also illegal to attempt to do any of those things. The definitions of harass and harm are fairly broad, meaning that species are protected from both direct and indirect adverse effects.
This broad definition is important. You don’t have to physically touch or kill an animal to violate the law. Disturbing its nesting site, destroying its habitat, or repeatedly approaching it in ways that interfere with normal behavior can all qualify as “harassment” under the ESA. For more context on how animals respond to threats and disturbance, it’s worth understanding how predator-prey dynamics shape wildlife behavior.
- Do not approach nesting sites — especially for shorebirds like the piping plover during nesting season.
- Do not handle or collect any animal you believe may be listed, dead or alive.
- Do not disturb hibernating bats in caves or structures — this is a critical threat for species like the little brown bat.
- Do not destroy, alter, or degrade habitat in ways that would harm a listed species, even on your own property (federal rules apply regardless of land ownership).
- Do not use pesticides or herbicides in ways that could directly or indirectly harm listed species or their food sources.
Common Mistake: Many people assume that if an animal wanders onto their property, they have the right to remove or harm it. This is incorrect. Wildlife in New Hampshire — including endangered species — remains protected by law regardless of where it is found.
The ESA prohibits any action that “takes” (adversely affects) a listed species, unless that action is done with a permit. The ESA has permit processes that allow various actors, including federal and state agencies or private companies or individuals, to adversely affect individuals of a listed species, provided that actions are taken to avoid and minimize adverse effects. If your project or activity might affect a listed species, pursuing the proper permits before proceeding — not after — is the right approach. You can also explore what happens to species that don’t receive timely protection by reading about extinct animals around the world.
Endangered Species on Private Land in New Hampshire
Private land and endangered species law is one of the most frequently misunderstood areas of wildlife regulation. Many landowners are surprised to learn that federal endangered species protections apply on private property just as they do on public land.
Wildlife inhabiting private land are not the property of a landowner, according to conservationists. More than two-thirds of New Hampshire’s land area is privately owned, according to the Society for the Protection of New Hampshire Forests. This means the vast majority of endangered species habitat in the state exists on land owned by private individuals, farmers, and businesses.
Since more than 80% of New Hampshire’s forests are privately owned, foresters and others working in the forest have a unique and critical role to play in conserving rare species. This is why private landowner engagement is central to any successful conservation strategy in the state.
If you own land in New Hampshire and an endangered species is found there, here is what you should know:
- Federal protections still apply. The ESA applies on all land, public or private. You cannot harm, kill, or harass a federally listed species on your property.
- State agencies may contact you. The Fish and Game Department might access private property for various reasons, including studying and tracking animals, conducting an environmental review, or for law enforcement reasons. Staff are expected to seek landowner permission before entering.
- You may be able to work with agencies. Candidate Conservation Agreements are made by the Fish and Wildlife Service with non-federal property owners to provide incentives for conserving candidate species so that they are not listed as endangered or threatened.
- Habitat Conservation Plans exist for complex situations. Habitat Conservation Plans contain information on the predicted effects of taking a species, how these effects will be minimized or mitigated, and how the plan will be funded. Meanwhile, the U.S. Fish and Wildlife Service attempts to assure property owners that they will not face additional land restrictions beyond those outlined in their Habitat Conservation Plans.
Pro Tip: If you’re planning construction, logging, or land clearing on your New Hampshire property, check with the NH Natural Heritage Bureau and NH Fish and Game before you begin. Discovering an endangered species mid-project is far more costly — legally and financially — than checking in advance.
It’s also worth noting that the relationship between private landowners and state wildlife agencies is currently a subject of active legislative debate in New Hampshire. House Bill 1603, a proposal from Rep. Sayra DeVito, seeks to add new requirements for how state agencies assess the presence of endangered and threatened species on private property. Several conservationists and biologists said the bill’s new language could result in harm to wildlife, diminishing the amount of data available to help scientists protect the environment and keep New Hampshire in compliance with the federal Endangered Species Act. This is an evolving area of law — stay informed.
How to Report an Endangered Animal Sighting in New Hampshire
If you spot what you believe is an endangered or threatened animal in New Hampshire, reporting it is one of the most valuable contributions you can make to conservation efforts in the state. Citizen sightings are a critical source of data for wildlife managers.
Location-specific observations are particularly valuable for species that are of higher conservation concern, including endangered and threatened species. It is also valuable to know that a particular species was observed in the same vicinity at different times.
Here’s how to report a sighting effectively:
- Use the NH Wildlife Sightings portal. The NH Wildlife Sightings system, developed by UNH and NH Fish and Game, allows you to submit verified wildlife observations online. All data collected through this site will be forwarded to wildlife professionals at NH Fish & Game, who will review and verify the individual records. Following quality control, data will be used for conservation planning and implementation by NH Fish & Game and our program partners.
- Document as much as possible. Historic observations may be reported, but are mostly of interest for rare species and will be more useful if well documented, such as with exact locations and photographs.
- Contact NH Fish and Game directly. You can reach the department at 603-271-3421 or by email at wildlife@wildlife.nh.gov for urgent or unusual sightings.
- Report bald eagle roosting sites. If an eagle is regularly observed roosting, landowners should report the bird to the NH Dept. of Environmental Services and minimize activity or physical disturbance around the tree.
- Respect private property. Participants in NH Wildlife Sightings must obey all local, state, and federal laws while collecting wildlife location data. Observers are strongly encouraged to get landowner permission before going onto private property.
Key Insight: Wildlife rehabilitators have noted that it is “already almost impossible” to get citizens to report animal sightings. Your report — even a simple one with a photo and GPS coordinates — genuinely helps scientists track population trends and protect species before they decline further.
You can also support reporting efforts indirectly by supporting organizations like NH Audubon, which conducts surveys and helps manage endangered birds in cooperation with NH Fish and Game.

Penalties for Harming or Taking an Endangered Animal in New Hampshire
The legal consequences for harming an endangered animal in New Hampshire can be severe, and they operate on two tracks: state law and federal law. You can face penalties under either or both, depending on the species involved and the nature of the violation.
Federal Penalties (ESA)
Taking a species generally includes causing any harm to a federally protected animal or plant species. Any individual that knowingly takes a listed species can be fined up to $25,000 by the federal government for each violation or instance. Criminal penalties, including imprisonment, are also possible for willful violations. Importantly, each animal harmed can constitute a separate violation.
State Penalties (NH RSA 212-A)
Under New Hampshire’s Endangered Species Conservation Act, violation of the Act is accomplished by taking a protected species and incurs a misdemeanor penalty. Enforcement officers have broad authority to act on violations. They can conduct searches as provided by law and execute a warrant to search for and seize any equipment, business records, merchandise, or plants taken, possessed, transported, sold, offered for sale, bartered, shipped, or otherwise used in connection with any violation. They can also arrest any person, without a warrant, who the officer has probable cause to believe is violating this chapter.
| Violation Type | Governing Law | Potential Penalty |
|---|---|---|
| Killing or harming a federally listed species | Federal ESA | Up to $25,000 fine per violation; criminal imprisonment possible |
| Taking a state-listed species | NH RSA 212-A | Misdemeanor criminal charge |
| Possessing, transporting, or selling a listed species | Federal ESA / NH RSA 212-A | Fines, seizure of property, criminal charges |
| Destroying critical habitat of a federally listed species | Federal ESA | Civil and criminal penalties |
It’s also worth noting what happens to any property or equipment used in a violation. At the time of arrest of any person in connection with any violation, law enforcement may search the person, premises, or business records and seize any plants, records, or property taken or used in connection with any alleged violation.
Important Note: These penalties are not just for poachers or developers. Ordinary citizens who accidentally disturb a nest, handle an injured animal without authorization, or destroy habitat without proper permits can also face legal consequences. When in doubt, contact NH Fish and Game before acting.
The best way to avoid penalties is straightforward: know the species in your area, follow proper reporting channels, and consult with the appropriate agencies before any activity that could affect protected wildlife. New Hampshire’s endangered animals — from the piping plover on its beaches to the timber rattlesnake in its rocky hillsides — depend on an informed public to survive. Understanding animals more broadly, including the biggest animals in the world and the most colorful animals, can deepen your appreciation for why biodiversity protection matters everywhere.
New Hampshire’s wildlife is a shared public resource — and protecting it is a shared legal responsibility. Whether you’re a landowner, a hiker, or a concerned resident, staying informed about the endangered animals in New Hampshire is one of the most meaningful steps you can take for the state’s natural heritage.
