Species information

The red wolf is the world’s most endangered wolf. Once common throughout the Eastern and South Central United States, red wolf populations were decimated by the early 20th century as a result of intensive predator control programs and the degradation and alteration of the species’ habitat. When the red wolf was first designated as a species “threatened with extinction” under the Endangered Species Preservation Act in 1967, the U.S. Fish and Wildlife Service initiated efforts to conserve and recover the species. Today, only about 20 red wolves roam their native habitats in eastern North Carolina as a nonessential experimental population (NEP), and approximately 245 red wolves are maintained in 43 captive breeding facilities throughout the United States. Studies are currently underway to identify the possibility of red wolf ancestry still remaining in the wild in southwestern Louisiana and southeastern Texas.

Appearance

The red wolf (Canis rufus) is a native North American canid intermediate in size between the coyote (Canis latrans) and gray wolf (Canis lupus). Red wolves are mostly brown and buff colored with some black along their backs, often with a reddish color on their ears, head and legs. Adult red wolves range in weight from about 45 to 80 pounds. Red wolves have wide heads with broad muzzles, tall pointed ears and long, slender legs with large feet. Red wolves stand about 26 inches at their shoulder and are about 4 feet long from the tip of the nose to the tip of the tail.

Habitat

In the late 1970s, red wolves in the wild were found only in southeastern Texas and southwestern Louisiana in coastal prairie and marsh habitat. However, any habitat in the Southeastern United States of sufficient size, which provides adequate food, water, and cover, could be suitable for the red wolf. Telemetry studies in eastern North Carolina indicate that red wolf home range requirements vary from about 20 to 80 square miles.

Diet

Although the exact diet of red wolves varies depending on available prey, it usually consists of a combination of white-tailed deer, raccoons and smaller mammals such as rabbits, rodents and nutria. The red wolf is an opportunistic feeder and can travel up to 20 miles a day or more to find food, which can be consumed at a rate of two to five pounds daily.

Behavior

Red wolves are social animals that live in close-knit packs. Typical packs consist of five to eight animals, including a breeding adult pair and their offspring of different years. Older offspring will often assist the breeding pair in pup rearing. Almost all offspring between one and two years of age will leave the pack or disperse to form their own pack.

Red wolves tend to form pair-bonds for life and mate once a year in February. Pups are typically born in April or May in well-hidden dens that may be located in hollow trees, stream banks and sand knolls. Dens have also been found in holes dug in the ground near downed logs or forest debris piles. Fewer than half of wolf pups born in the wild survive to adulthood. Survival rates are affected by disease, malnutrition and predation.

Wolf packs have specific territories that they actively defend against other canids, including other wolves. Most active at dusk and dawn, red wolves are elusive and generally avoid humans and human activity.

Threats

The primary threat to red wolves is human-caused mortality (e.g., gunshots, vehicle strikes), which can remove breeders from the wild red wolf population. These threats, combined with habitat fragmentation from increasing development, allow coyotes to expand into the NEP area. Coyotes can directly compete with red wolves for resources, as well as introduce diseases, and dilute red wolf genetic lines through hybridization. This is particularly true when a pack has lost one of the adults from the breeding pair close to mating season. Additionally, portions of eastern North Carolina where the current red wolf population is located are potentially subject to sea level rise as a result of climate change, which could pose a threat to their habitat.

Program history

The recovery of the red wolf began as a remarkable conservation success story. By 1972, the species was reduced to a small coastal area in southeast Texas and southwest Louisiana (see map above). From 1973-1980, the Service began trapping wild canids in the area to prevent extinction of the species and establish a captive breeding program with the intention of reintroducing the species in wild. In the early 1970’s, Point Defiance Zoo and Aquarium, in association with the Service, established a captive-breeding program using 14 red wolves. After numbers continued to decline due to human persecution and habitat loss, the red wolf was subsequently declared extinct in the wild in 1980.

In 1984, the captive breeding program was approved by the Association of Zoos and Aquariums as the Red Wolf Species Survival Plan (SSP) program, which provides oversight for maintaining a healthy and genetically diverse captive stock. By this time, there were approximately 63 individuals in the captive population and the SSP was actively growing the population through the coordinated efforts of the SSP partner facilities, making reintroduction efforts possible.

Recovery efforts in the wild began in northeastern North Carolina with the establishment of a nonessential experimental population, under section 10(j) of the Endangered Species Act, on Alligator River National Wildlife Refuge (NWR) in 1987. By 2011, this reintroduction effort culminated in a known population of 89 red wolves and an estimated population as high as 130 red wolves within the five county nonessential experimental population area. This was the first time a large carnivore had been declared extinct in the wild and then reintroduced in the United States. It set the stage for several subsequent reintroduction efforts that were modeled after the Red Wolf Recovery Program, such as gray wolves in Yellowstone and central Idaho, Mexican wolves in the southwestern U.S., California condors, and black-footed ferrets. Several innovative recovery tactics were first attempted by this program, with a great deal of success, including pup fostering and coyote sterilizations.

After reaching an estimated 130 red wolves in the wild in the late 2000s, the population has since declined dramatically. Human-caused mortality has been the leading cause of this decline. Hybridization with closely related coyotes, which is exacerbated by human-caused mortality, particularly in breeding pairs, and low red wolf population numbers also played a key role in this decline.

Current status of captive population

Today, there are approximately 245 red wolves in 43 SSP facilities across the country. The captive population is at capacity. In 2016, the Service made securing the captive population a priority and set a goal of a minimum of 400 animals with 52 breeding pairs in the captive population. The Service also stated it would provide resources to the SSP and work with the SSP and other partners to expand space capacity. To date, the Service has provided $514,000 through FY18 and FY19 Recovery Challenge Grants for the construction of additional red wolf enclosures.

Current status of wild population

After peaking at an estimated population of 130 red wolves (89 radio-collared), the nonessential experimental population in eastern North Carolina declined to an estimated 20, with only 10 being confirmed via active radio-collars. The total population is an estimate based on known radio collared red wolves, adult red wolves with radio collars that quit functioning relatively recently that are likely still on the landscape, and an additional few un-collared adult red wolves are thought to be on the landscape based on reported sightings and remote sensing cameras. The Service is working towards collaring all red wolves with bright orange collars to help the public distinguish them. Currently less than half of the red wolves have orange collars.

Due to declining population size and the mortality of one or both red wolves in established breeding pairs, there were no known red wolf pups born in the wild in 2019, which is the first time that has occurred in over 30 years. See below for management activities implemented to attempt to create red wolf breeding pairs in eastern North Carolina.

Management

Under Section 10(j) of the Endangered Species Act (ESA), the Service can designate reintroduced populations established outside of the species’ current range, but within its historical range, as “experimental.” This designation allows the Service to reestablish self-sustaining populations when doing so fosters its conservation and recovery. Management of the nonessential experimental population of red wolves in eastern North Carolina is conducted in accordance with the 10(j) rule published in 1995, with a permanent injunction issued by the U.S. District Court incorporated. The permanent injunction prohibits taking of red wolves either directly or by landowner authorization, without first demonstrating that the red wolf is a threat to human safety of the safety of livestock or pets.

In June 2018, the Service published a proposed revised 10(j) rule. In light of a federal court ruling issued in the Eastern District of North Carolina, the U.S. Fish and Wildlife Service has extended its review of this proposed rule to adapt its management of red wolves in the state. The additional review time will provide the Service the opportunity to fully evaluate the implications of the court decision.

Winter 2019-2020 management activities

In 1990, the Service established an island propagation site for the red wolf at St. Vincent National Wildlife Refuge (NWR), an isolated island off of the Gulf Coast of Florida. The role of this site is to propagate red wolf pups in a somewhat controlled, but natural environment that will provide them “wild experience” as juveniles for the purpose of being strategically translocated into the nonessential experimental population in eastern North Carolina.

In November 2019, there was an adult female, two sub-adults, and three pups living on St. Vincent NWR. This winter, the Service moved the sub-adult male red wolf from St. Vincent NWR to Alligator River NWR, in hopes of forming a new red wolf breeding pair with a female red wolf already residing on Alligator River NWR.

Additionally, the Service moved an adult male red wolf from Alligator River NWR to Pocosin Lakes NWR to attempt to form a new red wolf breeding pair with a female already residing on Pocosin Lakes NWR.

Both pairs of red wolves were placed in acclimation pens temporarily with their new perspective mates until being released on mid-February 2020. The time in the acclimation pen is intended to give the red wolf pair time to bond to one another and for the translocated red wolf time in the new area so they are more likely to remain. Since their release, their movements and activity patterns are routinely monitored.

Outreach and education

Partnership coordination calls

Every quarter, the Service and its partners in red wolf recovery meet via a conference call to provide updates on the status of red wolf related actions. The purpose of these calls is to:

  1. provide a forum for regular and effective coordination on current actions and collaborative efforts among all partners in red wolf recovery, and
  2. provide other interested parties and the public with updates on the status of red wolf conservation efforts.

The updates the Service provides on these calls can be found below

Community involvement

On Dec.10, 2019, the Service held a joint public information session with the North Carolina Wildlife Resources Commission regarding the red wolf recovery efforts and management of canids on the Albemarle Peninsula. The goal was to inform residents living in and around the five-county nonessential experimental population area in eastern North Carolina (Beaufort, Dare, Hyde, Tyrrell and Washington counties) about ongoing work and plans for canid management.

Prey for the Pack – Partners for Fish and Wildlife Program

Prey for the Pack is a new habitat improvement program through the Services’ Partners for Fish and Wildlife Program, in collaboration with the North Carolina Wildlife Federation, and is available to private landowners interested in and committed to improving wildlife habitats on their property. The program will help provide both technical and financial support to private landowners to help promote and implement habitat improvement projects that benefit both the landowner and the wildlife that depend on the resource, specifically to promote habitat for red wolf prey species. In exchange for financial and technical support, landowners will allow for the presence of red wolves on their private lands un-harassed.
