Endangered Species - AP Environmental Science

Population increase of target species. Population growth indicates improved survival and reproductive success.

Habitat restoration. Provides suitable habitat necessary for species survival and reproduction.

Competition for resources. Invasive species outcompete natives for food, space, and other resources.

Species survives only in captivity. No wild populations exist; species maintained only in zoos or breeding facilities.

Lack of resources and coordination. Limited enforcement capacity across international borders and jurisdictions.

Species with a critical role affecting many others. Disproportionate ecological impact relative to their abundance in ecosystems.

Recover endangered species to healthy populations. Mandates recovery plans and critical habitat designation for listed species.

Population decline of 50% over 10 years. IUCN criteria based on population trends and habitat loss rates.

Species that represents an environmental cause. Charismatic species that generates public support for conservation efforts.

Breeding programs and education. Ex situ conservation maintaining genetic diversity for potential reintroduction.

Isolated populations. Prevents gene flow and increases extinction risk for small populations.

Connect fragmented habitats. Allows species movement and gene flow between isolated habitat patches.

Variation within species; crucial for adaptation. Low genetic diversity reduces species' ability to survive environmental changes.

Critically Endangered. IUCN's highest risk category before extinction in the wild.

Conservation within natural habitats. Protected areas and reserves preserving species within their natural ecosystems.

Area with high endemic species and significant threats. Priority regions for conservation due to exceptional species richness.

Conservation outside natural habitats. Zoos, aquariums, and seed banks maintaining species outside natural environments.

Variety of life on Earth. Includes species diversity, genetic diversity, and ecosystem diversity.

Endangered Species Act of 1973. Federal law providing legal protection for threatened and endangered species.

Habitat destruction. Primary cause of species loss, accounting for over 80% of threats globally.

Overfishing. Depletes fish populations faster than they can naturally reproduce.

Approximately 28%. Global assessment showing accelerating biodiversity loss across all ecosystems.

Species protection laws. Legal frameworks providing formal protection from exploitation and habitat loss.

Plan to restore species to sustainable levels. Detailed strategy outlining specific actions needed for population recovery.

Increase population of endangered species. Controlled breeding to maintain genetic diversity and boost wild populations.

Education campaigns. Public education increases support for conservation policies and funding.

Convention on Biological Diversity (CBD). Global treaty promoting conservation and sustainable use of biological resources.

Contaminated habitats. Toxic substances poison species directly or accumulate in food chains.

Advocacy, research, and funding. Non-governmental organizations mobilize resources and expertise for conservation.
