When we think about wildlife protection in the United States, the Endangered Species Act (ESA) often comes to mind. Signed into law in 1973, the ESA has been critical in preventing the extinction of numerous species, from the bald eagle to the gray wolf. Yet, this landmark legislation has a significant blind spot: it primarily activates once species are already in crisis. For wildlife that isn’t yet endangered but whose populations are declining, legal protections remain woefully inadequate.
The Problem: Focusing on Crisis, Not Prevention
The ESA operates like an emergency room for wildlife—treating the most critical cases but not addressing the underlying conditions that lead to population decline. This reactive approach means we often intervene only when a species has reached the brink of extinction, when recovery is most difficult, expensive, and uncertain.
Meanwhile, across America, wildlife abundance is declining dramatically. The 2022 State of the Birds Report indicated that the U.S. has lost more than 3 billion birds since 1970—a staggering 29% decline. Similarly, insect populations are collapsing, freshwater species are disappearing at alarming rates, and even once-common mammals face mounting threats.
This phenomenon has been called “the empty forest syndrome”—ecosystems that appear intact but are missing their full complement of wildlife, resulting in diminished ecological function and resilience.
Current Legal Framework: The Protection Gap
The U.S. legal framework for wildlife protection consists of multiple laws, each with specific limitations:
- The Endangered Species Act (ESA): Only protects species officially listed as threatened or endangered. The listing process is often delayed by political pressure and limited resources.
- The Migratory Bird Treaty Act (MBTA): Protects migratory birds from being killed or captured without authorization but offers limited habitat protection. Recent interpretations have weakened protections against incidental harm.
- The Marine Mammal Protection Act (MMPA): Prohibits the “taking” of marine mammals but doesn’t address broader ecosystem concerns affecting their abundance.
- The Lacey Act: Primarily regulates trade in wildlife and prevents transport of injurious species but doesn’t proactively protect wildlife populations.
- State Wildlife Laws: Vary dramatically, often focus on game species, and frequently prioritize hunting opportunities over ecological abundance.
- The National Environmental Policy Act (NEPA): Requires environmental impact assessments for federal projects but doesn’t mandate wildlife-friendly outcomes.
Notably absent is any federal law that aims to maintain or restore the abundance of common wildlife species before they become imperiled.
The Consequences of Inadequacy of Legal Protections
The lack of legal mechanisms to protect wildlife abundance has profound ecological and social consequences:
Ecosystem Function Decline: Wildlife plays crucial roles in pollination, seed dispersal, pest control, and nutrient cycling. As populations thin, these ecosystem services diminish.
Trophic Cascades: When key species decline, it triggers ripple effects throughout food webs. For example, declining predator populations can lead to overabundant herbivores that damage vegetation.
Reduced Resilience: Biodiverse ecosystems with abundant wildlife are more resilient to climate change, disease outbreaks, and other disturbances.
Shifting Baseline Syndrome: Each generation accepts increasingly depleted wildlife populations as normal, lowering expectations for restoration.
Recreational and Economic Losses: Wildlife-related recreation contributes over $156 billion annually to the U.S. economy. Declining wildlife means fewer opportunities for hunting, fishing, wildlife watching, and associated economic activity.
Needed Legal Reforms
To address these challenges, several legal reforms could help protect wildlife abundance:
- Comprehensive Wildlife Abundance Legislation
The U.S. needs comprehensive legislation focused on maintaining healthy wildlife populations before they become endangered. Several conservation organizations and policymakers have advocated for reforms that would:
- Establish population baselines and abundance targets for key wildlife groups
- Require regular monitoring of wildlife populations
- Create funding mechanisms for proactive conservation
- Mandate consideration of wildlife abundance in land use decisions
- Establish incentives for private landowners who maintain wildlife habitat
- Strengthening Existing Protections
- Reform the ESA to include “depleted species” provisions that trigger interventions before endangered status
- Restore and expand MBTA protections to cover incidental take and habitat conservation
- Amend NEPA to require specific consideration of wildlife abundance in environmental assessments
- Landscape-Scale Conservation
- Establish legal frameworks for wildlife corridors connecting protected areas
- Create stronger habitat protection provisions in federal land management laws
- Develop standards for ecological integrity that include wildlife abundance metrics
- Private Land Incentives
Since most U.S. land is privately owned, reform should include:
- Tax incentives for maintaining wildlife habitat
- Expanded conservation easement programs
- Payment for ecosystem services programs that reward landowners for wildlife abundance
- “Working lands” programs that integrate wildlife conservation with agriculture and forestry
- Climate Change Provisions
Any new wildlife legislation must address climate impacts by:
- Protecting climate refugia where wildlife can persist as conditions change
- Requiring climate-smart conservation planning
- Facilitating assisted migration for species that cannot adapt in place
- Establishing robust monitoring systems to track climate impacts on wildlife
Success Stories and Models
Several existing programs demonstrate how wildlife abundance can be effectively protected:
North American Waterfowl Management Plan: This cooperative international effort has successfully maintained abundant waterfowl populations through habitat conservation and science-based management.
Partners for Fish and Wildlife Program: This voluntary program helps private landowners restore wildlife habitat on their property, demonstrating the potential of incentive-based approaches.
State Wildlife Action Plans: Though underfunded, these plans identify at-risk species before they become endangered and outline conservation strategies.
The Recovering America’s Wildlife Act (RAWA): This proposed bipartisan legislation would provide significant funding to states for proactive conservation of at-risk species. Though it has gained substantial support, its passage remains uncertain.
The Path Forward
Protecting wildlife abundance requires a fundamental shift in our legal approach—moving from crisis response to proactive conservation. This means:
- Shifting the burden of proof: Rather than requiring proof that activities harm endangered species, we should require demonstration that activities won’t diminish wildlife abundance.
- Embracing the precautionary principle: When faced with uncertain impacts, policy should err on the side of wildlife protection.
- Recognizing interspecies relationships: Legal frameworks should acknowledge ecological connections rather than managing species in isolation.
- Valuing abundance: Conservation targets should aim for ecologically functional populations, not just minimum viable populations.
- Democratizing wildlife governance: Wildlife management should incorporate diverse stakeholders beyond traditional hunting interests.
Conclusion
The ESA has been essential in preventing extinction, but it’s not enough. As wildlife faces unprecedented pressures from habitat loss, climate change, invasive species, and pollution, we need legal frameworks that maintain abundant wildlife populations before they reach crisis status.
By creating new legislation focused on wildlife abundance and reforming existing laws to be more proactive, the United States can ensure that future generations inherit not just the minimum number of species, but thriving ecosystems filled with abundant wildlife. The time for such reform is now—before more species join the endangered list and more ecosystems lose their ecological integrity. Given the current climate (both literally and politically), we likely need to start at the state and local level and by supporting nonprofit organizations who are putting together partnerships to do what can be done under current federal law.
The challenge is not just to prevent extinction, but to enable wildlife to flourish across American landscapes for generations to come.
