Wolf populations increase in protected areas, study finds

Uncategorized By Mar 29, 2023

Gray wolf populations are on the increase in protected areas throughout the US, according to a study by the National Park Service. Gray wolves came close to extinction due to continuous human activity, hunting and depletion of habitats. Following a 5.8% increase in populations of protected areas since 1995, wolf numbers have now more than tripled. More than 1,600 wolves are currently found in habitats covering more than 33% of the total US population. Wolves are still facing challenges due to climate change, disease and hunting and trapping.

Wolf populations increase in protected areas, study finds

A new study has found that populations of gray wolves, once on the brink of extinction, are now increasing in protected areas throughout the United States. The study, which was conducted by the National Park Service and published in the journal Biological Conservation, analyzed more than 20 years of data on wolf populations in National Parks and other protected areas.


Gray wolves were first listed as an endangered species in 1974, due to a combination of habitat loss, hunting, and other human activities that led to their near-extinction in the lower 48 states. In the decades since, efforts to protect and recover wolf populations have been ongoing, but progress has been slow and uneven.

One of the most effective strategies for wolf conservation has been the establishment of protected areas where hunting and other human activities are restricted. These areas provide a safe haven for wolves and other wildlife, allowing populations to grow and thrive over time.

Study findings

The new study analyzed data on wolf populations in 31 protected areas throughout the U.S., including National Parks, National Forests, and Wildlife Refuges. The researchers found that, overall, these populations have been increasing over the past two decades.

Specifically, the study found that:

  • Wolf populations in protected areas have grown by an average of 5.8% per year since 1995
  • The total population of wolves in protected areas has more than tripled over the past 20 years
  • Protected areas now contain more than 1,600 wolves, or about 33% of the total U.S. population

The study also found that populations in National Parks and other high-quality protected areas grew faster than those in lower-quality areas. This suggests that the quality of habitat and protection offered by these areas is a critical factor in the success of wolf conservation efforts.


The finding that wolf populations are increasing in protected areas is a positive sign for the future of these iconic animals. However, the researchers caution that the overall population of wolves in the U.S. remains well below historic levels, and that more work is needed to fully recover these populations.

Furthermore, there are ongoing efforts to roll back protections for wolves and other endangered species, which could threaten the progress that has been made. The authors of the study call for continued vigilance and support for wolf conservation efforts to ensure that these animals remain a vital part of the U.S. ecosystem.


Why are gray wolves important?

Gray wolves play a critical role in ecosystems as apex predators, helping to regulate populations of prey species and maintain the overall balance of natural systems. They also have significant cultural and symbolic importance for many indigenous communities and other people around the world.

What threats do wolves face?

Wolves face a range of threats, including habitat loss, hunting and trapping, disease, and climate change. These factors have contributed to their historic decline and continue to pose challenges for conservation efforts.

Are gray wolves still endangered?

Gray wolves are no longer listed as an endangered species under the Endangered Species Act, but they remain protected in certain states and areas where their populations are still recovering. Conservation efforts are ongoing to ensure that these populations continue to grow and thrive.

What can individuals do to support wolf conservation?

Individuals can support wolf conservation by supporting organizations that work to protect and recover wolf populations, advocating for policies that protect and restore wolf habitat, and educating others about the importance of these animals.
