Difference Between Endangered Species And Vs Threatened Species

The survival of countless species is threatened by factors like habitat loss, climate change, and human activities. Among these, some are categorized as endangered, while others are deemed threatened. These terms, often used interchangeably, have distinct meanings crucial for conservation efforts.

An endangered species faces a very high risk of extinction in the wild, whereas a threatened species is likely to become endangered in the foreseeable future. Understanding this distinction helps in prioritizing conservation strategies and legal protections tailored to the specific needs of each category.

Conserving biodiversity is vital for maintaining healthy ecosystems. The loss of species can lead to unforeseen consequences, impacting everything from food security to climate regulation. Differentiating between endangered and threatened species allows for targeted action plans, ensuring the survival of as many species as possible.

Definition of Endangered Species

Explanation of the Term ‘Endangered Species’

An endangered species is one that is at a high risk of extinction in the near future. This status is given to species whose populations have decreased significantly, making them vulnerable to various threats. The loss of habitat, hunting, and environmental changes are primary reasons these species face extinction.

Criteria for a Species to be Classified as Endangered

Several factors determine whether a species is classified as endangered:

  • Population Size: A species with a small population size is more likely to be classified as endangered.
  • Rate of Decline: Rapid population decline indicates a species is at high risk.
  • Geographic Range: Limited geographic distribution can make a species more vulnerable.
  • Fragmentation: Populations divided into small, isolated groups face higher risks.

Examples of Endangered Species Globally

  • Amur Leopard: Found in Russia and China, this leopard has fewer than 100 individuals left in the wild due to habitat loss and poaching.
  • Javan Rhinoceros: With fewer than 70 individuals remaining, the Javan rhinoceros is critically endangered, largely due to habitat destruction and hunting.
  • Mountain Gorilla: Found in the mountains of central Africa, this gorilla faces threats from habitat loss, poaching, and disease.

Definition of Threatened Species

Explanation of the Term ‘Threatened Species’

A threatened species is one that is likely to become endangered in the near future. While not as immediately at risk as endangered species, threatened species still face significant threats that could lead to their endangerment if not addressed.

Criteria for a Species to be Classified as Threatened

Factors that classify a species as threatened include:

  • Moderate Population Size: The population is not critically low but is declining.
  • Geographic Range: The species’ habitat is shrinking or facing threats.
  • Environmental Pressures: Changes in the environment pose risks to the species’ survival.

Examples of Threatened Species Globally

  • Polar Bear: Melting sea ice due to climate change threatens polar bears by reducing their habitat and access to food.
  • North Atlantic Right Whale: With fewer than 400 individuals remaining, this whale faces threats from ship strikes and entanglement in fishing gear.
  • African Elephant: Although not critically endangered, African elephants are threatened by poaching and habitat loss.

Legal Framework

Overview of International Laws Protecting Species

International laws play a crucial role in protecting endangered and threatened species. These laws provide frameworks for conservation efforts, regulate trade, and promote habitat protection.

  • Convention on International Trade in Endangered Species (CITES): This treaty regulates international trade in endangered species to prevent their exploitation.
  • Convention on Biological Diversity (CBD): A global agreement to promote sustainable development and the conservation of biodiversity.

Key Differences in Legal Protection for Endangered and Threatened Species

Legal protections vary between endangered and threatened species:

  • Endangered Species: Often receive stricter protections, including habitat preservation and bans on hunting and trade.
  • Threatened Species: May receive protections focused on preventing further decline, such as monitoring and habitat management.

Role of Organizations like IUCN and CITES

  • International Union for Conservation of Nature (IUCN): Maintains the Red List of Threatened Species, assessing the conservation status of species worldwide.
  • CITES: Regulates international trade to ensure it does not threaten the survival of species.

Causes of Endangerment and Threats

Human Activities Leading to Species Endangerment

Human activities are a major cause of species endangerment. Some key activities include:

  • Habitat Destruction: Deforestation, urbanization, and agriculture reduce natural habitats.
  • Pollution: Chemicals and waste products contaminate habitats and harm wildlife.
  • Hunting and Poaching: Illegal hunting for meat, trophies, and traditional medicine decimates populations.
  • Climate Change: Alters habitats and disrupts food sources, affecting species survival.

Natural Factors Contributing to Species Being Threatened

Natural factors also play a role in threatening species:

  • Natural Disasters: Events like earthquakes, hurricanes, and wildfires can destroy habitats and populations.
  • Disease: Outbreaks of disease can rapidly decrease populations.
  • Predation: Natural predators can contribute to the decline of certain species.

Comparative Analysis of Causes Affecting Both Categories

Both endangered and threatened species face similar threats, but the severity and immediacy of these threats can differ:

  • Endangered Species: Often face more immediate and severe threats, such as critical habitat loss or high rates of poaching.
  • Threatened Species: Face significant but less immediate threats, allowing for potential recovery if timely conservation actions are taken.

Conservation Status

The IUCN Red List Categories

The IUCN Red List is the most comprehensive inventory of the global conservation status of biological species. It categorizes species based on their risk of extinction. The key categories are:

  • Least Concern (LC): Species at low risk of extinction.
  • Near Threatened (NT): Species close to qualifying for a threatened category.
  • Vulnerable (VU): Species facing a high risk of extinction in the wild.
  • Endangered (EN): Species at a very high risk of extinction in the wild.
  • Critically Endangered (CR): Species at an extremely high risk of extinction in the wild.
  • Extinct in the Wild (EW): Species known only to survive in captivity or as a naturalized population outside its historical range.
  • Extinct (EX): Species with no surviving individuals.

Evaluating and Updating Species Status

The process of evaluating and updating the status of species involves several steps:

  • Data Collection: Gathering information on population size, trends, and threats.
  • Assessment: Using the IUCN criteria to evaluate the species’ risk of extinction.
  • Review: Experts review the assessment to ensure accuracy and consistency.
  • Publication: The updated status is published on the IUCN Red List.

Case Studies of Species Moving Between Categories

  • Giant Panda: Once classified as endangered, the giant panda was moved to vulnerable in 2016 due to successful conservation efforts, including habitat preservation and breeding programs.
  • Snow Leopard: Downgraded from endangered to vulnerable in 2017, reflecting improvements in population data and conservation actions.

Conservation Efforts

Strategies for Protecting Endangered Species

Effective strategies for protecting endangered species include:

  • Habitat Preservation: Protecting and restoring habitats to ensure species have a safe environment.
  • Anti-Poaching Measures: Implementing strict laws and surveillance to prevent illegal hunting.
  • Breeding Programs: Captive breeding and reintroduction programs to increase population numbers.
  • Legislation: Enforcing laws that protect endangered species and their habitats.
