Judge the ecological results, not the planting total. Trees planted are an activity measure. Biodiversity protection is an outcome: better habitat, healthier native and threatened species, improved ecosystem integrity or connectivity, reduced pressures, and recovery that persists. A credible project can show its starting condition, explain why planting fits that ecosystem, set measurable goals, monitor change repeatedly, report setbacks, and involve the people who hold rights and knowledge in the landscape.
What “protecting biodiversity” should mean
Biodiversity includes the variety of genes, species and ecosystems, plus the relationships that allow them to function. A project therefore needs a biological objective, not just a work plan. “Plant 100,000 trees” describes an operation. “Restore native woodland structure, increase occupancy of target bird species and reconnect two habitat patches by a stated date” describes an outcome that can be tested.

The distinction matters because a planting campaign can meet its numerical target while seedlings die, unsuitable species replace native vegetation, threats such as grazing or fire remain, or the site becomes no more suitable for wildlife than before. Planting can be an effective part of restoration, but only when it fits the ecosystem, addresses a defined conservation need and is followed by evidence of change.

#1 Best Overall
1. Check the ecological fit before counting trees
Identify the ecosystem and its natural reference condition
Ask what ecosystem the project is working in: for example, a particular forest type, wetland, savanna, shrubland or another locally defined system. The project should describe the site’s condition before work began and the reference condition it is trying to approach. A baseline might include vegetation structure, species records, soil or water conditions, fragmentation and known pressures.
A project that cannot describe the original ecosystem cannot convincingly explain why trees are the right intervention. Its justification should connect the chosen action to local ecological conditions and the stated conservation objective, rather than treating tree planting as universally beneficial.
Inspect species choice and provenance
Request the scientific and local names of planted species, their provenance, the number planted and the reason each was selected. Look for evidence that species are native or otherwise appropriate to the target ecosystem, that genetic sources suit local conditions, and that the mix supports the intended habitat rather than a short-lived plantation. The project should explain how soil, rainfall, elevation, fire, grazing and other site conditions affected the design where those factors are relevant.
Ask what would happen without planting
Good planning considers natural regeneration and other restoration options. If the site could recover after a threat is removed, planting may be unnecessary or secondary. A credible plan explains why active planting is needed, what complementary actions are required and how success will be judged against the baseline.
2. Demand a baseline, targets and a time-bound theory of change
Before accepting a claim, find the project’s baseline and targets in a public plan or monitoring report. The baseline is the reference point; targets specify the desired biological change and the date or decision point by which it should occur.
| Document or claim | Questions to ask | Evidence that strengthens it |
|---|---|---|
| Baseline | What was the site’s condition before intervention, and when was it measured? | Methods, maps, sampling locations, species lists and uncertainty are disclosed. |
| Objective | Which biodiversity feature is meant to improve? | The objective names an ecosystem, habitat feature, species group or threat, not only an area or tree count. |
| Target | What amount of change is expected, by when, and compared with what? | Specific, measurable targets with dates and a stated comparison or reference condition. |
| Activities | What will the project do to reach the target? | Planting is linked to site preparation, threat management, maintenance and community roles. |
| Attribution | How will the project separate its contribution from rainfall, surrounding land-use change or other programs? | A comparison design, repeated measurements or a transparent explanation of limitations. |
Targets should cover more than survival. A useful plan may set objectives for native species composition, habitat structure, connectivity, ecosystem integrity or a defined threat. It should also state what happens if the target is missed and who can change the management approach.
3. Look for biodiversity indicators beyond planting totals
Survival and planting totals are useful operational checks, but they are not proof of biodiversity recovery. Select indicators that match the site’s purpose and ecology; no single generic metric works everywhere.

- Presence, abundance, occupancy or recruitment of native species identified as priorities.
- Trends for threatened species or other species whose status motivated the project.
- Changes in species composition, including whether planted species are displacing desired native regeneration.
- Evidence that pollinators, decomposers, birds or other relevant functional groups are using the habitat.
Habitat and ecosystem condition
- Vegetation structure, age classes, canopy or ground cover where those features define the ecosystem.
- Soil, water or other physical conditions that underpin the target habitat.
- Indicators of ecosystem integrity, such as the presence of characteristic species and ecological processes.
- Connectivity between habitat patches, corridor function or reduction in fragmentation.
Threats and pressures
- Measured changes in the threats the project identified, such as damaging land use, invasive species, unsustainable extraction, fire or grazing where applicable.
- Whether management actions reduce exposure to those threats rather than merely adding vegetation.
- Evidence that gains are not being offset by degradation nearby or elsewhere in the project area.
A strong report explains why each indicator was chosen, how it was measured and what level of change would count as meaningful. It also distinguishes an indicator that is improving from proof that the ultimate conservation goal has been achieved.
4. Test the monitoring design
Monitoring should be repeated, transparent and matched to the ecology and objective. The available guidance does not establish one universal number of monitoring years for every ecosystem, so reject claims that rely on a fixed year-count rule detached from the site’s biology.
What a usable monitoring plan contains
- A schedule with sampling dates or seasons and a reason those intervals capture the relevant ecological response.
- Repeatable field methods, sampling locations, sample sizes and definitions for each indicator.
- Baseline measurements and, where feasible, reference or comparison sites.
- Quality controls, data limitations and an explanation of missing observations.
- Rules for changing management when survival, habitat or species indicators fall below target.
- Public reports that show raw or summarized results, not only a promotional headline.
Separate four kinds of statements in every report: what the project did, what was observed, what changed relative to the baseline, and what contribution can reasonably be attributed to the project. “We planted 50,000 seedlings” is an activity. “Seventy percent survived after the first dry season” is an observation. Neither statement alone demonstrates improved biodiversity.
Read setbacks as evidence of quality
Ecological work involves uncertainty. Credible managers disclose mortality, drought, fire, invasive species, altered methods and missed targets, then explain corrective action. A report that presents only successes, omits denominators or changes indicators without explanation is difficult to evaluate.
5. Check whether the project reduces the threats driving biodiversity loss
Restoration cannot be durable if the pressures that damaged the site continue unchecked. Ask which threats were identified, how severe they are and which intervention addresses each one. Planting may need to be paired with grazing management, invasive-species control, fire planning, water management, enforcement, land-use agreements or other locally appropriate measures.
Rank #3
Look for a continuing management plan rather than a completion date tied to the last planting day. It should assign responsibility, identify funding and describe maintenance, replacement planting where justified, monitoring and responses to new threats. A project can show strong early establishment yet lose its gains if management stops before the ecosystem is resilient.
6. Include rights, participation and local knowledge
Social and governance conditions affect whether ecological gains last. The International Union for Conservation of Nature (IUCN) emphasizes recognition of Indigenous peoples’ and local communities’ rights and roles, along with their participation in conservation implementation and monitoring.
Ask who owns or governs the land, who gave consent, who makes decisions, who is paid, and how complaints are handled. Participation should be more than providing labor or attending a launch event. Project documents should explain how local and Indigenous knowledge influenced species selection, fire or grazing practices, monitoring and decisions about access or use, while respecting confidentiality where appropriate.

7. Use major standards and metrics without overclaiming
SER International Principles and Standards
SER’s International Principles and Standards for the Practice of Ecological Restoration, third edition, was published in June 2026. SER presents the standards as guidance across restoration phases and notes alignment with global monitoring, reporting and verification platforms, including the Food and Agriculture Organization’s Framework for Ecosystem Restoration Monitoring. Use the standards as a planning and evaluation lens: define the reference ecosystem, set goals, select appropriate indicators, involve stakeholders and manage adaptively.
The Global Biodiversity Standard
SER lists The Global Biodiversity Standard manual, developed with partners including SER, Botanic Gardens Conservation International, Plan Vivo Foundation and CIFOR-ICRAF. It is intended to help tree planting, habitat restoration and agroforestry enhance biodiversity. Treat a standard or assessment as evidence about the criteria it actually checks. A label by itself does not prove additionality, permanence or site-level recovery; inspect the assessment scope, date, indicators and follow-up.
Kunming–Montreal Global Biodiversity Framework
The Kunming–Montreal Global Biodiversity Framework was adopted in December 2022. It sets four goals for 2050 and 23 targets for 2030 and has an associated monitoring framework. The framework supplies policy context for judging restoration claims, including attention to ecosystem integrity, connectivity and effective area-based conservation. It does not replace a site-specific baseline or monitoring design.
IUCN STAR
IUCN’s Species Threat Abatement and Restoration (STAR) metric estimates the potential contribution of specific, location-based threat-abatement and habitat-restoration actions to reducing species extinction risk. Its calculation uses species distributions, threats and extinction-risk data from the IUCN Red List. A STAR score is planning evidence about potential, not a measurement that recovery has already occurred. Read the score alongside observed habitat and species results.
The STAR page currently displays data for 5,362 threatened and Near Threatened species and says 56% of global extinction risk reduction could be achieved by restoring habitats. The page does not give a publication year for those displayed figures, so treat them as undated page figures rather than dated statistics and check the underlying source before using them in a formal comparison.
8. Compare two projects on the same axes
Do not let one project win because it reports a larger planting number. Apply the same questions and evidence threshold to both.
| Axis | Stronger evidence | Weak evidence |
|---|---|---|
| Ecological fit | Explains the ecosystem, reference condition, species provenance and why planting is appropriate. | Uses a universal tree target with no site-specific rationale. |
| Baseline and targets | Publishes starting conditions, biodiversity objectives and time-bound targets. | Reports area or seedlings without a biological baseline. |
| Outcome evidence | Tracks habitat condition, connectivity, relevant species and threats in addition to survival. | Uses photographs, totals or survival alone. |
| Monitoring | Repeats transparent methods, reports uncertainty and explains setbacks. | Provides a single post-planting snapshot or inaccessible methods. |
| Threat reduction and durability | Funds continuing management and measures whether identified pressures decline. | Ends accountability when planting is complete. |
| Rights and participation | Recognizes rights, decision-making roles, knowledge and grievance processes. | Counts outreach without explaining consent or influence. |
| Claims and attribution | Separates modeled potential, observed change and the project’s contribution. | Presents a score, certification or planting total as proof of recovery. |
For a simple internal review, score each axis as documented, partly documented or not documented, then record the missing evidence. This is not a universal certification scheme; it is a way to keep comparisons consistent.

9. Warning signs that a project may be selling activity as impact
- The headline is a very large tree number, while species, ecosystem and outcome targets are absent.
- “Native” is claimed without listing species, provenance or the ecological basis for selection.
- Success is reported as seedlings distributed or planted, with no survival denominator or later habitat data.
- Before-and-after photographs replace repeatable measurements.
- A modeled carbon, biodiversity or STAR figure is described as observed recovery.
- The project has no public baseline, methods, uncertainty statement or failure report.
- Threats such as grazing, fire, invasive species or land-use pressure are acknowledged but not managed.
- Monitoring stops immediately after planting, with no funded responsibility for later care.
- Local or Indigenous communities appear only as beneficiaries in promotional copy, not as rights holders or monitoring partners.
- A framework name or badge is used without explaining what was assessed, when, by whom and with what follow-up.
10. A practical due-diligence sequence
Use this sequence before donating, approving a project or repeating its claims.
- Define the decision. Decide whether you are testing ecological impact, social safeguards, climate claims or all three. Do not let a strong result in one category substitute for evidence in another.
- Request the project plan. Obtain the ecosystem description, baseline date, reference condition, species list, objectives, targets and management responsibilities.
- Trace the intervention. Ask why planting is needed, what alternatives were considered, how species and provenance were selected, and which threats the work addresses.
- Inspect the monitoring protocol. Check indicators, sampling locations, timing, comparison or reference sites, data quality controls and the process for changing management.
- Read the latest results. Separate activities, observations, changes from baseline and attributed contribution. Look for mortality, uncertainty and missed targets.
- Verify governance. Confirm recognition of land and resource rights, consent, participation in decisions and monitoring, benefit sharing and complaint channels.
- Test durability. Identify who will manage the site after planting, for how long, with what funding and against which future threats.
- Classify the claim. Label it as an activity claim, modeled potential, observed ecological change or demonstrated contribution. Only the last two categories address whether biodiversity is actually improving, and they still require context.
11. How to interpret common answers
“We planted one million trees.”
Ask how many survived, which species were planted, whether the mix fits the ecosystem, and what biodiversity outcome changed. Until those questions are answered, the statement demonstrates scale of activity, not protection.
“Our score shows high biodiversity impact.”
Identify what the score measures, its data sources, geographic scope and time period. If it is a STAR score or another model of potential, do not treat it as observed recovery. Request field measurements that test the modeled expectation.
“We follow a recognized standard.”
Ask which edition, assessment boundary, indicators and verification process apply. Standards can improve planning and transparency, but they do not automatically establish additionality, permanence or a positive site-level trend.
“The community was consulted.”
Find out whether consultation affected decisions, whether consent was obtained from the appropriate rights holders, how benefits and risks are shared, and whether communities participate in continuing monitoring and governance.
What a convincing evidence package looks like
A persuasive project file is coherent from ecology to governance: a site-specific baseline leads to measurable biodiversity targets; the intervention and species choices fit the ecosystem; threat management supports the restoration; monitoring is repeated with checkable methods; results include failures and uncertainty; modeled tools are labeled as potential; and local and Indigenous rights and roles are respected. The file also identifies who will manage the site and pay for that work after the initial planting campaign.
If the only readily verifiable result is a planting total, describe the project accurately as a planting activity. If repeated measurements show better habitat condition, native or threatened species trends, connectivity or threat reduction against a baseline, you have grounds to call it biodiversity protection—subject to the limits and time frame of those measurements.
