Register, Monitor, and Care for Urban Trees—Together

Tree Taishi is a citizen-science platform that empowers communities to map urban trees, track tree health, and learn their climate value. It blends mobile-first design, AI-assisted insights, and privacy-respecting data to accelerate greener, more resilient cities.

A Living Map of Urban Trees

Scan a QR tag, register a tree, and watch the city’s canopy come alive on a shared map.

What is Tree Taishi?

Tree Taishi (“Ambassador Tree”) is a research-driven, community platform to register and monitor urban trees. The project explores digital MRV (monitoring, reporting, verification), app-based engagement, and on-the-ground stewardship to help cities grow healthy, climate-resilient canopies.

Why it matters

  • Urban trees cool cities, store carbon, and improve health.
  • Citizen participation accelerates data coverage and care.
  • Digital tools make monitoring consistent, transparent, and scalable.

What you can do

  • Register a tree and add basic attributes (species, size, photo).
  • See trees on a shared map; follow care notes and updates.
  • Learn climate value with simplified estimates and guidance.
  • Join campaigns to expand canopy coverage in your district.

Key Features

Built for mobile. Designed for community. Informed by research.

Mobile-First App

Fast onboarding, clean inputs, and simple flows to log trees anywhere.

Tree IDs & Tags

Optional QR tags bind a physical tree to its digital profile.

Digital MRV Basics

Consistent fields and timestamps for learning and future analytics.

Campaigns & Community

Neighborhood challenges and school drives to expand urban canopy.

Learning & Tips

Simple guidance on species care, watering, and risk signs.

Roadmap

Upcoming: richer health indicators, stewardship badges, and open data exports.

How it works

A simple loop of register → observe → learn → care.

1) Register

Add a tree with location, photo, and basic attributes. Each entry is time-stamped to support responsible use later on.

2) Monitor

Update observations—new growth, pruning, or risks like pests and heat stress. Build continuity over time.

3) Learn & Act

See simplified climate value, care tips, and neighborhood activity. Join drives to plant and maintain trees.
