Endangered Animals in Rhode Island: What the Law Says and Which Species Are at Risk

Rhode Island may be the smallest state in the country, but its salt marshes, barrier beaches, rocky islands, and inland forests support a surprisingly wide range of wildlife — including dozens of species that are now fighting for survival. Rhode Island’s 1,214 square miles are home, or at least were, to 41 federally and/or state endangered or threatened species. That number represents mammals, birds, fish, reptiles, insects, mollusks, and amphibians — many of which you might never realize are at risk unless you know where to look.

Understanding which animals are protected, what legal frameworks govern them, and what your responsibilities are as a resident, landowner, or visitor is more important than ever. Whether you encounter a nesting shorebird on a barrier beach or discover a rare turtle crossing your property, the rules apply to you. This guide breaks down everything you need to know about endangered animals in Rhode Island — clearly and without the legal jargon.

How Endangered Species Are Listed and Protected in Rhode Island

Endangered species protection in Rhode Island operates on two tracks: federal law and state law. Both carry legal weight, and in many cases, a single animal may be protected under both simultaneously.

The federal Endangered Species Act (ESA) of 1973 provides for the identification, listing, and protection of both threatened and endangered species and their habitats. ESA administration and enforcement are the responsibility of the U.S. Fish and Wildlife Service and the National Marine Fisheries Service. At the federal level, a species can be classified as either “endangered” — meaning it faces imminent extinction — or “threatened,” meaning it is likely to become endangered in the foreseeable future.

The United States Congress created the Endangered Species Act to “provide a means whereby the ecosystems upon which endangered species depend may be conserved to provide a program for the conservation of such species.” Threatened species are not as close to extinction but are at significant risk, and species are listed for many reasons, but often their declines are the result of human impacts such as habitat loss and introduction of invasive species.

At the state level, Rhode Island has its own parallel system. When a species naturally part of Rhode Island’s biota is in danger of extirpation from the state, law (RIGL 20-37-2) allows the Department of Environmental Management (RIDEM) to list it as such — this is the rare and endangered species list or “natural heritage” list — and policies can then be promulgated to try to prevent further decline of listed species.

The Rhode Island Natural History Survey (RINHS) is a nonprofit that tracks rare species in the state in collaboration with DEM and helps to create the official Natural Heritage lists, for both plants and animals, which are protected under state endangered species law. The listing of rare species is an ongoing process requiring annual revisions to reflect the best scientific information available concerning the circumstances of rarity, as well as increased knowledge of the native fauna.

Key Insight: A species can be listed at the state level, the federal level, or both. State listing offers some protections, but federal listing under the ESA generally carries stronger enforcement mechanisms and broader habitat protections.

Federally Listed vs. State-Listed Endangered Animals in Rhode Island

One of the most common points of confusion is understanding the difference between federal and state listings — and why it matters for how an animal is protected.

Rhode Island is home to a number of rare plants and animals, which hold both state and federal listings. The state’s ESA protects those plants and animals identified by the Rhode Island Natural Heritage Program, which conducts a statewide inventory of rare and vulnerable species. However, the strength of that protection differs significantly depending on which list a species appears on.

Rhode Island law does not mention “take” in the same terms as neighboring states. While it’s unlawful to physically take an endangered species and keep it as a pet or sell it, if a new development could impact the animal’s habitat leading to a “take,” the state’s regulatory oversight is weaker unless it is within a designated wetland. This is a meaningful gap compared to states like Massachusetts, which triggers a project review whenever a development occurs within a rare species habitat.

Endangered species laws vary from state to state, and Rhode Island laws lack some protections that have been codified by its New England neighbors. “The regulatory frameworks that currently exist for protecting wildlife in Rhode Island are inadequate,” according to the state’s Community Wildlife Conservation Guide.

The federal government provides funding for state-run programs that aim to protect threatened species, which can include inventory of species as well as funding for the acquisition of identified threatened habitats. This federal support is critical, as Rhode Island’s own enforcement infrastructure has faced resource constraints in recent years.

Notable Endangered Animals Found in Rhode Island

The list of animals at risk within Rhode Island’s borders and in its waters includes mammals, birds, fish, reptiles, insects, a mollusk, and an amphibian. Here is a closer look at some of the most significant species — and the threats they face.

American Burying Beetle

Once common across 35 states, the American burying beetle has now retreated to a few scattered pockets of land, and one of its last strongholds in the Northeast is in Rhode Island, on Block Island. This beetle plays a surprisingly important role in the ecosystem — it buries small dead animals, which helps recycle nutrients and keeps the soil healthy.

Some blame habitat loss, while others point to changes in carrion availability. There’s even a theory that the beetle’s decline may have been linked to the extinction of the passenger pigeon, which once provided a major food source. By the late 1980s, the beetle had vanished from almost everywhere in New England, except Block Island.

Roger Williams Park Zoo has taken a leading role in captive breeding, raising thousands of beetles in its lab to help reintroduce them to sites in Massachusetts and elsewhere. Block Island now supports more than 40 state and federal rare or endangered species, including the globally endangered American burying beetle.

Pro Tip: If you visit Block Island, stay on marked trails — the beetle’s habitat is extremely sensitive to foot traffic and disturbance, especially during summer breeding months.

North Atlantic Right Whale

The North Atlantic right whale is one of the federally listed species that can be found in Rhode Island waters. These marine mammals are dying faster than they can reproduce — they rarely die of natural causes; instead, they are struck by ships or suffer fatal injuries from fishing gear. The latest preliminary estimate suggests there are fewer than 350 remaining, including less than 100 breeding females.

They have been listed as endangered under the Endangered Species Act since 1970. If more isn’t done to protect them, scientists have projected the species could become extinct in about 20 years. Rhode Island’s offshore waters sit along their migration corridor, making vessel speed restrictions and gear modifications particularly important in this region.

Northern Diamondback Terrapin

The northern diamondback terrapin is state-listed as endangered, and its population has suffered greatly due to poaching and habitat loss. Development has divided habitat into small pieces, resulting in islands of resources separated by roads and other uninhabitable landscapes — this is especially detrimental to turtles since they require both wetland habitats and adjacent upland habitats for nesting.

Roseate Tern

The roseate tern is federally listed as endangered — specifically its northeastern nesting population. It gets its name because of the bird’s rosy breast during the breeding season. Researchers and volunteers monitor tern colonies, install nesting shelters, and actively manage predator activity. While the largest colonies are now found in Massachusetts, a few breeding pairs have returned to Rhode Island, including on protected islands managed by the U.S. Fish and Wildlife Service.

Atlantic Sturgeon

The Atlantic sturgeon — an anadromous fish in Rhode Island and one of the oldest species in the world — now holds a place on the Endangered Species list. This ancient fish migrates between saltwater and freshwater rivers to spawn, and Rhode Island’s 500+ dams make this transition difficult.

Leatherback Sea Turtle

The leatherback sea turtle is one of the ocean’s true giants. Adults can reach up to seven feet long and weigh as much as a small car. Every summer, a few of these massive turtles pass through the waters off Rhode Island’s coast, part of a long migration that stretches from the Caribbean to the cold waters of the North Atlantic.

New England Cottontail

The New England cottontail is the only native rabbit species in Rhode Island, and it has become increasingly rare across the state. These rabbits once thrived in thick, brushy areas filled with shrubs and young trees. Rhode Island’s New England cottontail population has not fared well over the last century, as the species requires dense regeneration — a stage of forest succession that is no longer abundant. If you’re interested in other animals facing similar pressures in neighboring states, see our coverage of endangered animals in Virginia and endangered animals in West Virginia for comparison.

Important Note: Several birds listed as state-endangered in Rhode Island — including the pied-billed grebe, American bittern, northern harrier, peregrine falcon, and barn owl — are based on the status of their breeding populations in the state, not their overall global status.

What You Cannot Do Around Endangered Animals in Rhode Island

Both federal and state law impose clear restrictions on how you may interact with — or impact — endangered animals. Ignorance of these rules is not a legal defense.

Under Rhode Island’s state endangered species law, it is illegal to “buy, sell, offer for sale, store, transport, import, export, or otherwise traffic in any animal or plant or any part of any animal or plant whether living, dead, processed, manufactured, preserved, or raw if the animal or plant has been declared to be an endangered species.”

At the federal level, the prohibition goes further. The Endangered Species Act makes the taking of an animal on the endangered or threatened species list illegal. According to the act, to “take” is to “harass, harm, pursue, hunt, shoot, wound, kill, trap, capture, or collect or attempt to engage in any such conduct.”

Here is a breakdown of prohibited actions under both state and federal law:

• Hunting, trapping, or killing any federally or state-listed endangered or threatened animal
• Harassing or disturbing endangered animals, including disrupting nesting, feeding, or breeding behavior (federal law)
• Buying, selling, or trafficking any part of a listed animal — including feathers, shells, bones, or skin
• Transporting or exporting a listed species or its parts across state or national lines
• Possessing a listed animal without a valid federal or state permit
• Destroying critical habitat in ways that would harm federally listed species (federal law)

The only exception to these prohibitions is for purposes of scientific research or educational display, either of which must be done by or under the formal supervision of a legitimate college or university — and then only upon the issuance of a special permit for each individual excepted species. The permit may be issued by the director of environmental management.

Common Mistake: Many people assume that simply observing or photographing an endangered animal is always fine. While passive observation is generally permitted, approaching too closely — especially near nesting sites — can legally constitute “harassment” under the federal ESA and may result in enforcement action.

You should also be aware that several reptiles are covered under regulations of the Rhode Island Division of Fish and Wildlife, which identifies several species as “protected,” meaning possession without a permit is prohibited at all times. This includes sea turtles found in offshore Rhode Island waters. For a broader look at animals with unique survival traits, explore our guide on animals immune to snake venom.

Endangered Species on Private Land in Rhode Island

One of the most frequently misunderstood aspects of endangered species law is how it applies to private landowners. Owning land does not exempt you from federal or state wildlife protections.

Under the federal ESA, if a listed species lives on, nests on, or passes through your property, you are still prohibited from taking that animal. Federal critical habitat designations can also affect what you are permitted to do with your land, particularly if you plan to develop or significantly alter it.

At the state level, Rhode Island’s protections on private land are narrower. While it’s unlawful to physically take an endangered species and keep it as a pet or sell it, if a new development could impact the animal’s habitat leading to a “take,” the state’s regulatory oversight is weaker unless it is within a designated wetland. The regulations within Rhode Island’s Freshwater Wetlands Act address rare species and rare wetland types, but these regulations only apply within jurisdictional wetlands and fall short of disallowing significant impacts to rare species even within this jurisdiction.

In practical terms, this means:

• If you find a federally listed animal nesting on your property, you cannot disturb or remove it without federal authorization
• If your property contains a state-listed species but falls outside a regulated wetland, Rhode Island state law may offer less direct protection against habitat disruption from private activities
• If you plan to develop land near known rare species habitats, contacting RIDEM before beginning work is strongly advisable
• Voluntary conservation agreements and habitat management plans are available through RIDEM and can provide landowners with legal certainty

The federal law also created the Cooperative Endangered Species Conservation Fund to award grants to states for voluntary projects on non-federal lands. This means funding may be available to help private landowners support habitat conservation — not just restrict their activities. You can support wildlife on your own property by enhancing the availability of habitat features like tree age diversity, dead woody material, natural food sources, and clean water.

Pro Tip: Before purchasing or developing land in Rhode Island, request a Natural Heritage review from RIDEM. This can reveal whether any rare or endangered species have been documented on or near the property — potentially saving you from costly legal complications down the road.

Private land stewardship is increasingly critical as space needed for human play, combined with relentless development, leaves a shrinking amount of habitat for at-risk species in Rhode Island.

How to Report an Endangered Animal Sighting in Rhode Island

If you spot what you believe is a rare, threatened, or endangered animal in Rhode Island, reporting your observation can make a genuine difference. The Rhode Island Natural History Survey encourages the submission of heritage species observations to improve the value of the heritage database for all purposes, and provides official Animal Observation Report forms for this purpose.

The information staff is gathering includes where a species was found (latitude, longitude, and municipality), who found it, and what conditions it was in (sick or healthy), and that information goes into a database. The more precise your report, the more useful it is to conservation planners.

Here is how to report an endangered animal sighting in Rhode Island:

1. Document what you saw — Note the species (or your best description), the exact location (GPS coordinates if possible), the date and time, and the animal’s behavior or condition
2. Photograph if possible — A photo is strong evidence but never approach, disturb, or handle the animal to get a better shot
3. Submit an observation report — Use the official Animal Observation Report form provided by the Rhode Island Natural History Survey (RINHS), available on their website
4. Contact RIDEM directly — For urgent situations (injured animal, active nesting under threat, or suspected illegal activity), contact the RIDEM Division of Fish and Wildlife at 401-789-0281 or email DEM.DFW@dem.ri.gov
5. Report illegal activity separately — If you witness someone harming, trapping, or trafficking a protected animal, contact RIDEM’s law enforcement division or the U.S. Fish and Wildlife Service immediately

Key Insight: Conservationists are often cautious about publicizing exact locations of rare species. Often conservationists are reticent to advertise the locations of rare species to protect their vulnerable populations. When reporting, submit details through official channels rather than posting precise locations on social media.

After five decades of activity, the natural heritage methodology is well understood and broadly supported by the public, and is therefore particularly effective and valuable. Your sighting report directly feeds into the data systems that inform conservation decisions, land-use planning, and future species listings.

Penalties for Harming or Taking an Endangered Animal in Rhode Island

Penalties for violating endangered species protections in Rhode Island come from two sources: state law and federal law. Both can apply simultaneously, and federal penalties are substantially more severe.

State Penalties (Rhode Island RIGL Chapter 20-37)

Violation of Rhode Island’s endangered species act results in fines from $500 to $5,000 or up to one year imprisonment, or both. These penalties apply to anyone who buys, sells, stores, transports, imports, exports, or otherwise traffics in a state or federally listed endangered species or any part of one.

Federal Penalties (Endangered Species Act)

Possession, sale, removal, and transport of endangered species is prohibited under the federal ESA, and can carry both civil and criminal penalties for violations. Federal civil penalties can reach up to $25,000 per violation, while criminal penalties for knowing violations can reach up to $50,000 per violation and one year in prison. Repeat offenders or commercial-scale violators face escalating consequences.

Who Can Be Penalized

Under Rhode Island law, “person” means any individual, firm, company, corporation, business, manufacturer, wholesaler, retailer, warehouse operator, transporter, importer, exporter, state or municipal agency, club, or any other group, organization, or individual. This broad definition means that businesses, nonprofits, and government agencies are all subject to the same penalties as private individuals.

Important Note: Penalties can stack. A single incident — for example, illegally capturing and selling a protected turtle — could result in simultaneous state and federal charges, meaning you could face prosecution and fines from both jurisdictions for the same act.

The ESA has been one of the country’s most effective tools for ensuring human activities that may adversely affect endangered and threatened species and their habitats are avoided or significantly reduced, preventing the extinction of 99% of species listed under the Act since its inception in 1973. Its enforcement record reflects that seriousness.

For broader context on extinct animals and what happens when protections fail, the consequences are clear: once a species is gone, no law can bring it back. Rhode Island still has time to protect what remains — but that window depends on awareness, compliance, and collective action.

Conclusion

Rhode Island’s endangered animals are not just ecological statistics — they are living indicators of the health of the state’s ecosystems. From the American burying beetle on Block Island to the North Atlantic right whale in offshore waters, these species face real and ongoing threats from habitat loss, development, pollution, and climate change.

As someone living in, visiting, or owning land in Rhode Island, understanding the legal framework that protects these animals matters. Both state law under RIGL Chapter 20-37 and the federal Endangered Species Act impose clear prohibitions, carry meaningful penalties, and place responsibilities on individuals and businesses alike. The gap between Rhode Island’s state protections and those of neighboring states makes federal enforcement and voluntary conservation efforts all the more important.

If you spot a rare species, report it. If you own land near known habitats, consult RIDEM before making changes. And if you witness illegal activity involving a protected animal, contact authorities immediately. Small actions across thousands of residents add up to meaningful protection for species that cannot advocate for themselves.
