The Iberian wolf (canis lupus signatus) is a distinct subspecies of the grey wolf, native to the Iberian Peninsula. Historically, these wolves roamed extensively across Spain and Portugal, thriving in various habitats, including forests, plains, and mountainous regions. Their presence was widespread and their populations robust, symbolizing the wild and untamed nature of the region. Before the dramatic decline in their numbers, the Iberian wolf population was estimated to be quite substantial, although exact numbers are challenging to ascertain. They inhabited almost all of Spain and Portugal, adapting to diverse landscapes ranging from dense forests to open plains and rugged mountains.
The Early 20th Century Decline of the Iberian Wolf
The decline of the Iberian wolf population began in earnest in the early 20th century, although pressures on their population started earlier. Several factors contributed to this rapid decline:
In the 19th and early 20th centuries, wolves were aggressively targeted through government-supported bounty hunting and eradication campaigns, as they were seen as a direct threat to livestock and human safety. Common methods included poisoning, using toxic substances like strychnine in carcasses, and trapping, which led to significant wolf mortality. Additionally, deeply ingrained cultural attitudes, fueled by negative folklore and myths depicting wolves as malevolent creatures, further justified and intensified their persecution.
Deforestation for timber, agriculture, and urban expansion drastically reduced wolf habitats, leading to fragmented landscapes and scarce prey. Agricultural expansion further worsened the situation by reducing prey availability and increasing human-wolf conflicts, especially as livestock grazing encroached on former wild areas.
Overhunting deer and wild boar, which are primary prey for wolves, led to a scarcity of food resources. This forced wolves to turn to livestock, further increasing conflicts with humans.
By the mid-20th century, the Iberian wolf population had dwindled to critically low levels, with their range in Spain restricted to the northern regions and virtually eradicated in the south and center. In Portugal, wolves were increasingly isolated in the north. By the 1960s, fewer than 400 wolves remained in Spain, with even fewer in Portugal, bringing the species to the brink of extinction. However, conservation efforts began in the 1970s, leading to population recovery in the following decades through legal protections, habitat conservation, anti-poaching measures, and public awareness campaigns.
Importance of the Iberian Wolf
The Iberian wolf is a keystone species, meaning its presence and activities have a significant impact on the structure and functioning of ecosystems. Their role in the ecosystem includes:
Wolves play a crucial role in maintaining the balance of their ecosystems through a trophic cascade effect. By controlling the populations of herbivores like deer and wild boar, wolves help prevent overgrazing and promote the growth of vegetation. This, in turn, supports a variety of other species and maintains the health of the ecosystem.
Wolves regulate prey populations, promoting plant regeneration and creating microhabitats that support diverse wildlife. Additionally, carcasses left by wolves provide food for scavengers, supporting various species and aiding nutrient cycling in the ecosystem.
Wolves control smaller predator populations, like foxes and wildcats, reducing pressure on smaller prey species and allowing them to thrive. By affecting prey behavior and distribution, wolves act as ecosystem engineers, shaping landscapes and promoting ecological processes that benefit many species.
Saving the Iberian wolf is not just about preserving a single species; it's about maintaining the ecological integrity of the regions they inhabit. Their conservation is vital for the health of the ecosystems and the countless species that rely on them.
Grupo Lobo and Their Conservation Efforts
Grupo Lobo is a leading conservation organization dedicated to the protection and recovery of the Iberian wolf in Spain and Portugal. Established in 1985, the organization focuses on scientific research, public education, and practical conservation initiatives to ensure the long-term survival of this iconic species. One of their key projects is the Centro De Recuperacao Do Lobo Iberico (Iberian Wolf Recovery Centre), which was created in 1987 to provide a safe and suitable environment for wolves that cannot be released back into the wild due to factors such as trapping, abuse, illegal captivity, or coming from zoos and parks.
My volunteer experience:
In 2022, I volunteered at the Iberian Wolf Recovery Centre in Mafra, Portugal, a sanctuary established by Grupo Lobo. The center spans 17 acres and offers the best captive conditions for wolves that cannot be returned to the wild. The sanctuary runs an ongoing volunteer program where participants can stay for 2 to 4 weeks, living on-site and contributing to various tasks that benefit the resident wolves. These tasks include forest maintenance, preparing food for the wolves, and conducting behavioral observations.
During my time there, I worked alongside other like-minded volunteers, under the guidance of a dedicated team of wildlife biologists and ecologists. We contributed to the daily management of the sanctuary, learning about wolf behavior and conservation efforts firsthand. I highly recommend this volunteer program to anyone interested in gaining a deeper understanding of the Iberian wolf and making a meaningful impact on their conservation.

Research and Monitoring
Grupo Lobo conducts extensive research and monitoring activities to gather crucial data on wolf populations, behavior, and habitats. This includes:
Population Monitoring: Researchers use GPS collars to track wolf movements and behavior, identifying critical habitats and potential conflict zones with human activities. Camera traps are deployed to capture images and videos, providing insights into population size, pack dynamics, and reproduction. Field surveys also play a role, gathering scat samples, tracks, and other signs to estimate wolf population density and distribution.
Genetic Studies: Researchers conduct genetic analyses to assess the diversity and structure of wolf populations, which is essential for understanding inbreeding, gene flow, and connectivity. By collecting DNA from non-invasive sources like scat and hair, they can monitor individual wolves and track genetic changes over time.
Habitat Conservation and Restoration
Ensuring the availability of suitable habitats is key to wolf conservation. Grupo Lobo works on:
Protected Areas: Efforts are being made to establish and expand protected zones to secure key wolf habitats and migration corridors, ensuring safe environments for wolves to live and breed. Additionally, habitat management plans are developed and implemented to address the specific needs of wolves, including prey availability and suitable denning sites.
Habitat Connectivity: Efforts include implementing wildlife corridors to restore and maintain habitat connectivity, reducing fragmentation to facilitate genetic exchange and population stability. Additionally, landscape restoration projects, such as reforestation, wetland restoration, and invasive species control, are undertaken to enhance habitat quality and promote biodiversity.
Reducing Human-Wolf Conflicts
To promote coexistence between wolves and human communities, Grupo Lobo focuses on reducing conflicts through:
Livestock Protection Measures: Conservation efforts promote the use of trained guard dogs, like the Spanish Mastiff and Portuguese Cão de Gado Transmontano, to protect livestock from wolf attacks. Farmers are also encouraged to install electric fencing around enclosures and use secure night shelters for livestock to minimize the risk of predation.
Compensation Programs: Efforts include supporting financial compensation schemes and promoting livestock insurance programs to reimburse farmers for losses due to wolf predation. These measures help reduce retaliatory killings and promote tolerance towards wolves.
Public Awareness and Education
Public support is crucial for wolf conservation. Grupo Lobo engages in:
Educational Programs: Educational efforts include developing school programs on the ecological role and conservation of wolves, featuring classroom presentations, field trips, and interactive activities. Additionally, workshops and seminars are organized for farmers, policymakers, and the public to raise awareness and promote coexistence with wolves.
Outreach Campaigns: Public engagement efforts involve media campaigns, social media, and community events to foster positive perceptions of wolves and dispel myths. Additionally, educational materials like brochures, posters, and documentaries are produced and distributed to emphasize the importance of wolf conservation.
Advocacy and Legal Protection
Grupo Lobo collaborates with government agencies, policymakers, and other stakeholders to advocate for stronger legal protections and effective conservation policies for the Iberian wolf. Their efforts include advocating for laws against hunting, trapping, and poisoning, as well as developing sustainable land use practices. When necessary, they take legal action to challenge harmful practices or policies that threaten wolf populations. Grupo Lobo works closely with key agencies like:
Instituto da Conservação da Natureza e das Florestas (ICNF): The ICNF is the main governmental body responsible for nature conservation and forest management in Portugal. Grupo Lobo collaborates with the ICNF on various conservation projects, habitat restoration efforts, and wolf monitoring programs.
Portuguese Environment Agency (APA): The APA is responsible for environmental protection and sustainable development in Portugal. Grupo Lobo works with the APA to promote policies that support the conservation of the Iberian wolf.
By implementing these strategies, Grupo Lobo plays a crucial role in the conservation of the Iberian wolf, working to ensure their survival and fostering a harmonious relationship between wolves and human communities.
