Observe
Notice something new, unusual or changing. You do not need to be a scientist or identify the cause.
SIGNANATURA · A HUMAN OBSERVATION NETWORK
Nature speaks in signals.
People often notice changes in nature before those changes become structured data. SignaNatura gives those observations a place to be documented, responsibly reviewed and connected into a wider picture.
Reviewed before publicationEvery submitted observation is checked before becoming public.
Observer identity stays privateNames and contact details are not published.
Sensitive locations protectedExact locations are generalized before publication.
Humans remain responsibleAI may support the work, but people review and publish the content.
Humans observe. Communities share. AI helps analyze.
Technology can help connect information, but every signal begins with a person who noticed that something had changed.
Describe
Tell us what you noticed, when and where—and how it differs from what you consider normal.
Review & protect
Each submission is reviewed before publication. Personal details and sensitive locations remain protected.
Why SignaNatura exists
Small observations can preserve knowledge before it disappears.
Nature often changes quietly: fewer insects, a familiar bird arriving at a different time, plants flowering earlier, water behaving unusually or a once-familiar place no longer feeling the same. People who know a place may notice these shifts before they become formal data.
One observation is not proof of wider environmental change. But when observations are preserved and compared over time, they can reveal questions that deserve closer attention.
Our responsibility
Listen carefully. Protect people. Do not overstate.
Human reviewEvery observation is reviewed before it can be published.
Privacy and location protectionContact details stay private, and sensitive locations are generalized.
Clear limitsA citizen observation is a signal for closer attention—not automatic scientific proof.
Responsible use of AIAI may support analysis and illustration, but public content remains under human editorial responsibility.
Who is behind SignaNatura?
A personal concern growing into a shared mission.
SignaNatura is being developed in Finland by Simo Rönkkö, a futures researcher and technology professional with more than 30 years of ICT experience—and a lifelong interest in nature and birds.
It began with a simple concern: important changes may first be noticed by ordinary people who know a place deeply. The initiative is still developing openly, step by step, with a clear distinction between observations, supporting analysis and established scientific knowledge.

Why SignaNatura Exists
Nature’s earliest warnings may first be noticed by people who know a place deeply.

Do not assume it is too small. Describe honestly what you noticed—you do not need to prove the cause. We will review the observation before publication.
