Poaching is the illegal hunting or harvesting of wildlife. In AP Environmental Science (Topic 9.9), it's a key human-caused selective pressure that pushes species toward extinction, which conservation laws and anti-poaching legislation try to combat.
Poaching is the illegal hunting or harvesting of wild animals or plants, usually for meat, trophies, or valuable parts like ivory, horn, or fur. It falls under EK EIN-4.B.1, which lists "being extensively hunted" as one of the factors that can push a species toward extinction. When that hunting is illegal and persistent, it becomes poaching.
Here's the AP framing that matters: poaching is an anthropogenic (human-caused) selective pressure. It doesn't kill randomly. Poachers target the biggest tusks, the rarest furs, the most valuable individuals, which removes exactly the animals that would otherwise help a population recover. That's why species like African elephants and snow leopards stay on the edge of extinction even when other threats are managed. The fix the CED points to is making poaching illegal through legislation and then enforcing it, so the success of a conservation plan often comes down to whether anti-poaching laws actually work on the ground.
Poaching lives in Unit 9: Global Change, specifically Topic 9.9 Endangered Species, and supports learning objective AP Enviro 9.9.A, which asks you to explain how species become endangered and what strategies combat the problem. It's a concrete example of EK EIN-4.B.1 in action. The exam loves using charismatic megafauna (elephants, rhinos, snow leopards) as the case study because their decline ties together hunting pressure, habitat loss, and policy responses. If you can explain why criminalizing poaching reduces a selective pressure, you can answer a whole cluster of endangerment questions.

Extinction Risk (Unit 9)
Poaching is one of the biggest levers that raises a species' extinction risk. Species with slow reproduction or already-small populations, like elephants, can't replace individuals fast enough to outrun the killing, so poaching tips them from threatened to endangered.
Protected Areas (Unit 9)
Protected areas like national parks and reserves are the physical front line against poaching. Drawing a boundary only helps if you can keep poachers out, which is why anti-poaching enforcement and protected-area strategy are basically two halves of the same plan.
Captive Breeding Program (Unit 9)
When poaching crashes a wild population, captive breeding becomes a backup to rebuild numbers. But it's a band-aid if poaching continues, because you'd just be releasing new animals into the same threat that wiped out the originals.
Conservation Easement (Unit 9)
A conservation easement protects habitat on private land, addressing the habitat-loss side of endangerment. It pairs with anti-poaching laws because protecting the place and protecting the animals in it are two different threats that both need solving.
Poaching shows up most directly in endangered-species questions, often using African elephants as the example. The 2017 SAQ Q2 opened with large animals like African elephants and snow leopards "on the verge of extinction," which is exactly the poaching scenario. On multiple choice, expect stems asking you to identify how anthropogenic selective pressures endangered the African elephant (the answer involves targeted hunting for ivory), or to pick the metric that best measures whether anti-poaching legislation is working. On FRQs, you may need to name poaching as a cause, explain why it raises extinction risk, and then propose or evaluate a strategy like enforcement, protected areas, or captive breeding. The trick is matching the solution to the root cause: criminalizing and enforcing against poaching addresses the hunting pressure directly.
Both involve killing wild animals, but poaching is illegal, unregulated, and often targets endangered or protected species. Legal hunting is regulated through licenses, seasons, and quotas designed to keep populations sustainable. The word "poaching" on the AP exam almost always signals a threat to an endangered species, not managed harvest.
Poaching is the illegal hunting or harvesting of wildlife and is a direct cause of species endangerment under EK EIN-4.B.1.
It counts as an anthropogenic (human-caused) selective pressure, often targeting the most valuable individuals like elephants with large tusks.
The CED's main fix is criminalizing poaching through legislation, so anti-poaching laws and their enforcement are the go-to strategy on the exam.
Poaching shows up under Topic 9.9 in Unit 9 and supports learning objective AP Enviro 9.9.A.
African elephants and snow leopards are the classic exam examples, used in both the 2017 SAQ Q2 and several practice MCQs.
Poaching is the illegal hunting or harvesting of wildlife. In AP Enviro it's a human-caused factor (EK EIN-4.B.1) that pushes species like the African elephant toward extinction, and it's combated through anti-poaching legislation under Topic 9.9.
No. Hunting can be legal and regulated through licenses, seasons, and quotas that keep populations sustainable, while poaching is illegal and often targets endangered or protected species. On the exam, "poaching" almost always signals a threat to an endangered species.
Poaching acts as a selective pressure that removes specific high-value individuals, such as elephants with the largest tusks, faster than slow-reproducing species can replace them. For populations that are already small, this can tip them from threatened to extinct.
Poaching directly kills animals through illegal hunting, while habitat loss removes the places they need to live. They often hit the same species at once, which is why effective conservation plans pair anti-poaching enforcement with protected areas or conservation easements.
It appears in endangered-species questions, often using African elephants or snow leopards, like the 2017 SAQ Q2. You may need to identify poaching as an anthropogenic selective pressure, explain why it raises extinction risk, or evaluate a metric that measures whether anti-poaching legislation is working.
