As restoration is in itself an intricate network of interrelated actions, it makes sense that the best option to achieve long-term success is to use a holistic approach towards ecosystem restoration. With this in mind, Plant-for-the-Planet has developed restoration/reforestation guidelines covering biological, social, and economic aspects to ensure high quality projects are supported by our platform.
These standards build on academic literature and the International Principles and Standards for the Practice of Ecological Restoration (by SER et al.), the Principles for Ecosystem Restoration to Guide the United Nations Decade 2021–2030 (by UN Environment Program, FAO et al.), and the Road to Restoration (by WRI & FAO).
We would love to receive any comments, feedback, or suggestion.

b. some vegetation/ shrub
c. established vegetation (native or invasive) - Unintended negative consequences
- Project context
- No conversion of non-forest ecosystems to forest
- No cutting of native forest (Cutting of invasive/ non-native species is allowed to improve ecosystem health)
- Potential negative consequences of planting considered (e.g., no planting of fast growing non-native species in agroforestry projects in arid systems where they could disrupt the water table,; planting high densities of evergreen trees where ecosystems are deciduous dominated).
- Project is developing opportunities to contribute to regional conservation goals

3. Planting
- Does the system require tree planting?
- Density – number of trees per ha - % of each species
- Height / age of plants
- No afforestation or planting in areas that have rapid rates of natural regeneration. Assisted Natural Regeneration (ANR) is allowed.
- Max. 10,000 trees /ha (high density only permissible if survival rates are low)
- ~ 30cm height / 3 months in nursery
- Max. 10,000 (tree species planted in mixtures)
- ~ 30cm height / 6 months in nursery
SELF-REPORTED
- TreeMapper – pictures of plants.
- Site visits
PLAUSIBILITY CHECK
Questionnaire
- Method of clearing
- Removal of trees
Width of stems removed
- Fire, only allowed If the system is fire adapted. If using fire, have a clear protocol.
- No cutting existing trees (unless invasive)
PLAUSIBILITY CHECK

4. After Planting
PLAUSIBILITY CHECK
- Questionnaire
- Site visits
For areas where work has been done for less than 5 years: less than 70% of the area and projects actively working on depleting it.
For areas where work has been done for 5 years or more: Less than 50% OR no clear visual dominance
*Planting of invasive species in agroforestry systems is not allowed. If there is an already present invasive species useful for the community, the project can maintain it (but not plant more) if special measures to avoid spreading or damages to the ecosystem are being applied.
For areas where work has been done for less than 5 years: less than 50% or no clear visual dominance.
For areas where work has been done for 5 years or more: less than 25%, whenever possible, or present just in small patches/almost eradicated or not representing a threat to the ecosystem.
VERIFIED
Site visits - random visit of at least 5 points
All trees planted by the project, not just the ones funded through donation through our site, must be registered with TreeMapper.
Max. 12 months delay in updating after planting.
All trees donated to the project, not just the ones funded through a donation through our site, must be registered with TreeMapper or provide the specific data.
Max. 8 months delay in registering newly planted trees.

All uses must follow:
- sustainable forest management
For restoration projects:

These standards were developed based on scientific works and international guidelines (SER, IUCN, UN, FAO).
Projects must meet at least 27 of the 32 minimum standards (including all of the 10 obligatory standards) to receive donations via the Plant-for-the-Planet platform.
To qualify as a top project, you must meet at least 12 of the 20 top standards.
If you don’t meet all the requirements but you have good reasons and want to be part of the platform, feel free to reach out to us and share your project details. We will evaluate these and determine if certain exceptions to certain standards can be made depending on the project objectives, approach, and community benefits.
To continuously improve our standards, they are reviewed at least once a year or whenever a major change is needed due to new scientific insights or evidence. Any adjustments to the standards have to be approved by the Restoration Project Review Board. For new projects joining the platform, the new standards are effective immediately. For all projects already on the platform, their review status stays valid for at least two years. After announcing changes to the standards, all projects already on the platform get six months to adjust to the new standards. In case they are up for a review after those six months (i.e. the two years that a review stays valid at least are over), they will be reviewed according to the new standards.
We believe collaboration is the best way to achieve a goal, so we invite you to review our standards. In case you have any questions, feedback, or suggestions, please share them with Samantha Davalos, samantha.davalos@plant-for-the-planet.org
We are happy to hear from you.
