Silva Metrics for residents and volunteers: getting to know and caring for green spaces
How residents see the town's green spaces with Silva Metrics: a record for each tree by scanning a QR code, reports with follow-up and plantings by schools and associations.
Who this page is for
For people who live in a town and notice its trees: neighbours, families, schools and associations that look after a garden or plant a corner.
What it solves
A street tree is often a stranger, and whoever spots a problem does not always know whom to tell. Silva Metrics links each element to its record and to a clear reporting channel.
What it offers
The record of every tree, bench or fountain
A QR code opens a record written in plain, walking-pace language. Get to know what is next to you, with no account and nothing to install.
Reports with follow-up
You report a sick tree, a fallen branch or a broken fountain with a photo. You see where your report stands.
Privacy when you look
Lookups are counted without identifying anyone. The local government learns what interests people, not who looked.
Volunteers, schools and associations
A planting by a school or an association is recorded with photos and dates. Their effort stays visible and is not lost over the years.
Use cases
- A stroll. You scan a linden and find out when it blooms.
- An empty tree pit. You report it with a photo and see it get resolved.
- A school planting. The school’s trees, with their story, in the inventory.
How it is used
- You see a QR code on a tree or a fountain.
- You scan it and read its record.
- If something is wrong, you report it with a photo.
