The final step is to connect your uploads to a .
A Project is where your story, goals, updates, and evidence come together. Linking evidence helps other people understand what happened, where it happened, and what data supports your work.
Good evidence is not just a file. It should include enough context for someone else to understand why it matters.
Where evidence comes from
Evidence can come from the upload options covered in this section:
Species observations, field photos, dates, locations, and notes uploaded through Add observations.
AI-assisted biodiversity observations created through on Telegram.
Larger datasets reviewed case by case, such as tree data, drone imagery, survey exports, field photo archives, or structured data.
Sound recordings and deployment records from workflows.
Link evidence from the Project page
On a Project page, users can add an update and attach optional evidence.
You can use this when you want to:
- explain what the evidence shows
- add context around a field activity
- attach multiple records to a Project update
- share files, reports, or external links
- keep your Project timeline updated over time
What can be linked as evidence?
The main evidence types should match the upload options covered in this section:
Species observations, field photos, dates, locations, and notes from the Add observations flow.
Biodiversity observations created through Tainá, including AI-assisted species suggestions and field notes.
Reviewed batch data such as tree data, drone imagery, survey exports, field photo archives, or other structured data.
Sound recordings, deployment records, playable previews, or spectrograms from AudioMoth workflows.
You can also add supporting material directly from the Project update flow:
- write a short description or update explaining what happened
- add pictures or image files
- attach sounds or audio files
- attach videos
- attach documents, reports, audits, methodologies, certificates, or testimonials
- add external links to websites, dashboards, maps, reports, datasets, or other evidence platforms
Accepted additional file formats
For direct file evidence, supported formats include:
JPG, PNG, GIF, WebP, AVIF, and SVG.
MP4, WebM, MOV, and M4V.
MP3, WAV, M4A, OGG, FLAC, and AAC.
PDF, text, Markdown, HTML, RTF, Word documents, spreadsheets, and presentations.
HTTP or HTTPS links to reports, websites, dashboards, maps, datasets, or other evidence platforms.
When adding a file as evidence, users can choose a content type such as Document, Report, Audit, Evidence, Testimonial, Methodology, Photo, Video, Dataset, Certificate, Sound, or Other.
File evidence currently supports files up to 10MB per file in the Project evidence flow. Datasets should generally use the batch upload process, especially if they are large, structured, or need GainForest team review before being linked to a Project.
Link observations during upload
When adding observations, you can link them directly to a Project before publishing.
You can also upload observations first and link them to a Project later.
Good evidence includes context
When linking evidence, add a short note if possible. Explain:
- what the evidence shows
- who collected it
- when it was collected
- where it was collected
- why it matters for the Project
This makes the evidence easier to understand for people who were not present during the fieldwork.
Why this matters
Linked evidence helps a Project become more useful for:
- impact reporting
- grant applications
- partner updates
- community visibility
- funder review
- showing long-term stewardship
