Question

The local park is dealing with deer overpopulation while wolf numbers are declining. You’re helping park rangers understand these population changes and their effects on the ecosystem.
Question 1 (11.111111111 points)

Based on population ecology principles, what approach would provide the best long-term solution for managing the deer overpopulation problem sustainably?
Question 1 options:

Restore natural predators and improve habitat connectivity

Build barriers to contain deer in specific areas

Remove all deer and restart with smaller populations

Supplement deer food sources to reduce competition

Answer 1

Best choice: Restore natural predators and improve habitat connectivity.

Why: Re-establishing predators and reconnecting habitats restores natural predator–prey dynamics and metapopulation processes that keep deer numbers near the ecosystem’s carrying capacity without continual human intervention. Predators reduce deer density and alter deer behavior in ways that can reduce overbrowsing and help vegetation recover (trophic cascades). Improved connectivity also allows gene flow, recolonization, and more resilient populations for multiple species.

Why the other options are inferior:
- Building barriers only shifts the problem, fragments habitat, reduces genetic exchange, and can concentrate browsing damage.
- Removing all deer and restocking is extreme, costly, disruptive to ecosystem functions, and risks repeating the problem unless ecological drivers are fixed.
- Supplementing food increases carrying capacity, can boost reproduction and densities, spreads disease, and doesn’t address the root cause.

Implementation should be done cautiously (feasibility studies, stakeholder engagement, phased predator reintroductions or corridor creation, monitoring, and adaptive management).
