Umbrella species

Beauval - Panda géant 06

Umbrella species are a concept in conservation biology where the protection of these species indirectly conserves the many other species that make up the ecological community of its habitat. Umbrella species are selected for conservation-related actions because protecting these species inadvertently protects the many other species that share their habitat. The term comes from the idea that these species act as an "umbrella" covering the protection needs of multiple other species.

Definition and Importance

An umbrella species is typically a large species with extensive habitat requirements or a species that is easy to monitor. By focusing conservation efforts on these species, conservationists can ensure the protection of a large number of co-occurring species and the ecosystems they inhabit. This approach is particularly useful in areas where conservation resources are limited, allowing for the efficient allocation of resources towards the protection of broad areas of habitat.

Criteria for Selection

The selection of an umbrella species is based on several criteria:

• Large Home Range: The species should have a large home range that overlaps with the habitats of many other species.
• Ease of Monitoring: The species should be relatively easy to monitor, making it a practical choice for conservation efforts.
• Ecological Requirements: The species should have specific ecological requirements that, when protected, also protect a wide range of other species.
• Public Appeal: Often, the species has a certain charisma or public appeal, making it easier to generate support and funding for conservation efforts.

Examples

• The tiger (Panthera tigris) in Asia is an example of an umbrella species. By protecting large areas of forest for the tiger, countless other species that share this habitat are also protected.
• The northern spotted owl (Strix occidentalis caurina) in North America serves as an umbrella species for old-growth forest ecosystems, protecting a wide array of species that depend on this habitat.

Challenges

While the concept of umbrella species is widely used, it is not without its challenges. Critics argue that focusing on a single species may overlook the needs of other species that require different habitat conditions. Additionally, the success of this approach depends on the correct identification of umbrella species and the assumption that their protection will indeed cover the needs of other species in the habitat.

Conservation Strategies

Conservation strategies involving umbrella species often include creating protected areas, restoring habitats, and implementing policies that benefit the umbrella species and, by extension, the broader ecosystem. These strategies require collaboration among governments, conservation organizations, and local communities to be effective.

Conclusion

Umbrella species serve as a valuable tool in conservation biology, offering a pragmatic approach to biodiversity conservation. By protecting these key species, conservationists can safeguard the broader ecological communities they represent. However, this approach should be used in conjunction with other conservation strategies to ensure the protection of all species and their habitats. 0
