1Repair Windows errors before they cause bigger problems2Fix the driver behind crashes, sound loss and screen glitches3Clear out junk files and repair common Windows errorsWhen wildlife funding is limited, prioritize the proposal with the strongest additional conservation benefit for its full cost and risk—not the one with the most ambitious technology. De-extinction may warrant support if it can show a durable, measurable benefit and does not displace more effective work for living species. A 2017 model found that funding resurrected populations could leave fewer threatened species conserved in the scenarios it examined, making opportunity cost a central question rather than a reason to dismiss every project.
What does “de-extinction” actually produce?
“De-extinction” is shorthand, not a promise to recreate an extinct animal exactly. The IUCN Species Survival Commission’s 2016 guidance says current approaches cannot restore an extinct species in its complete genetic, behavioral, and physiological form. They aim to create a proxy: an organism intended to resemble the extinct species or provide some of its ecological function. IUCN SSC guidance

That distinction matters when judging conservation value. Producing an animal, particularly one that can live in captivity, is not by itself a conservation outcome. A proposal needs a credible route from research and captive care to appropriate habitat, ecological function, and a managed release and monitoring plan. The relevant question is what benefit the proxy would deliver in the intended place, and whether that benefit could be achieved more effectively another way.
What evidence says about the funding tradeoff
The warning from de-extinction scenarios
A 2017 analysis modeled candidate projects in New Zealand and New South Wales. It concluded that public funding for resurrected populations could result in fewer living threatened species being conserved under the scenarios studied. The authors found that outcome could persist even with optimistic assumptions about outside sponsorship of resurrection and cost-sharing. They also noted that fully external sponsorship could create benefits, while cautioning that discretionary money still has an opportunity cost if it could instead conserve living species. This is a scenario-specific finding, not a forecast for every species, place, donor, or future technology. Bennett et al., 2017

Evidence for action on living species
Conventional conservation is not guaranteed to work, but there is evidence that interventions can improve outcomes. IUCN’s 2024 account of a meta-analysis reports that conservation actions improved biodiversity or slowed decline in 66% of analyzed cases compared with no action. That percentage describes the cases studied; it is not the probability that any particular project will succeed. The account cites lower deforestation in managed logging concessions and improved nesting success following predator management, while calling for more rigorous research across additional interventions and countries.

Compare the proposals on equal terms
A fair comparison looks beyond a headline research milestone or a single year of spending. It asks what each investment would achieve, what it would consume over time, and what would happen if it were not funded.
Rank #2
| Decision question | De-extinction proxy proposal | Living-species conservation proposal |
|---|---|---|
| What outcome is promised? | A defined ecological function or contribution to reducing extinction risk at a specified site—not simply the creation of a proxy. | A defined change in the status of a living species, the threats it faces, or the habitat it depends on. |
| What costs and capacity are required? | Account for research, captive population management, habitat preparation, transport, release, post-release care, monitoring, contingency response, and staff time. | Account for the full intervention and the ongoing management needed to address the relevant threats; do not assume a conventional project is cost-free or certain to succeed. |
| What is the counterfactual? | Identify which conservation work or capacity would lose funding if the proposal proceeds, and whether the money is genuinely additional. | Identify what this intervention adds compared with no action or another feasible use of the same funds. |
| What alternatives can deliver the function? | Compare the proxy with an extant ecological replacement and other interventions that could meet the same goal. | Compare the proposed action with other approaches to reducing the species’ threats or extinction risk. |
| How will risks and results be managed? | Set release, welfare, ecological-risk, monitoring, and stop-or-adapt criteria before implementation. | Set measurable success criteria, monitor effects, and adjust or stop if results or impacts differ from expectations. |
The table is a decision framework, not a claim that every project in either column has the same costs or prospects. No general, comparable lifetime dollar cost is established for a named de-extinction project paired with a specific living-species alternative; avoid treating a universal cost-per-species comparison as available.
Test additional funding instead of assuming it
A private donor, technology company, or special campaign may say it will pay for a proxy without taking money from an existing conservation budget. That can improve the case, but the funding source alone does not prove that the money or capacity is additional. Ask what the donor would otherwise have funded, whether public grants or conservation staff will be redirected, and whether the project depends on habitat protection and long-term management that another program must provide.
Rank #3
Include the full program, not just the research or animal-creation phase. IUCN guidance specifically identifies captive management, habitat preparation, transport, release, post-release care, monitoring, and contingency response as resource demands. Those commitments can extend beyond a launch or a short grant cycle. The guidance also says to make diverted resources and opportunity costs explicit. IUCN SSC guidance
Ask whether a living ecological replacement could do the job
Some proposals seek to restore a lost ecological function, not merely to conserve a particular lineage. In those cases, the comparison should include existing species that might provide that function. IUCN SSC says a suitable ecological proxy may be found among extant species and advises comparing the proposed proxy with alternatives such as translocation. A living species may be easier, less costly, quicker, and better understood; the de-extinction proposal needs to show why it would achieve the intended function with less cost or risk, or otherwise provide a distinctive benefit. IUCN SSC guidance
Location is essential to this test. The proposal should identify suitable habitat, whether the original threats are controllable, and how the expected ecological benefit will be measured there. The IUCN Species Threat Abatement and Restoration (STAR) metric can help estimate how specific investments may contribute to reducing extinction risk. It is a tool for informing choices, not a substitute for project-specific evidence about feasibility, cost, or risk. IUCN STAR metric

A conservation rationale does not eliminate the need to assess harm. Before a release, decision-makers should examine animal welfare and impacts on surrogate animals, as well as pathogen risks, invasiveness, hybridization, human-wildlife conflict, and wider ecosystem effects. They should also ask whether a release can be controlled or reversed if the results are harmful.
Feasibility depends on people and institutions as well as biology. Confirm local community consent, Indigenous Peoples’ approvals where relevant, and the capacity of local partners to manage the project over the long term. Set goals, monitoring methods, and criteria for stopping or adapting the work in advance; report results and tradeoffs so that promised benefits can be checked against observed outcomes. These questions are central to IUCN SSC’s call for an explicit conservation rationale, comparison with extant alternatives, transparent accounting, and long-term risk and monitoring plans. IUCN SSC guidance
How to make the funding decision
- Define the conservation outcome. State the species, site, threat, or ecological function the proposal is intended to benefit, and how success will be measured.
- Build the full-cost plan. Include development, ongoing care, habitat and threat management, release, monitoring, contingency, and the staff capacity required over the program’s life.
- Compare feasible alternatives. Evaluate action for living species and any extant ecological replacement that could deliver the same function, using the same outcome and time horizon.
- Establish additionality. Document the donor or public funder’s counterfactual allocation and identify any conservation funds, staff, or local capacity that would be diverted.
- Set risk and accountability rules. Agree on welfare and ecological safeguards, local participation, monitoring, and thresholds for changing or stopping the project.
- Fund the strongest net case. Favor the option with the clearest additional benefit after costs, opportunity costs, feasibility, and risks are considered—not the one with the most novel technology or the largest headline.
What current conservation initiatives do—and do not—show
In 2026, IUCN announced the Phoenix Species Project with a stated commitment of $200 million at launch and a planned scope of 100 highly threatened or Extinct in the Wild species across 30 countries. Those are the initiative’s announced commitment and intended reach, not completed recovery outcomes. The announcement illustrates one way funding can be organized around threatened-species recovery; it does not by itself establish that every project is effective or directly comparable with a de-extinction proposal.
