Endemic or Invasive? 
The Endemic or Invasive? Sorting Wall is an interactive, walk‑up activity where patrons sort species images into two categories: species native to Montana and species that are invasive. Using Velcro, magnets, or laminated cards, patrons can explore biodiversity, learn ecological concepts, and optionally use iNaturalist to deepen their understanding. The wall functions like a hands‑on mini exhibit that requires no staff supervision.

A Simple, Eye‑Catching Wall Setup
Designate a section of wall or a bulletin board with two clearly labeled areas for sorting species. Provide Velcro or magnetic zones for attaching the species cards so patrons of all ages can walk up and interact at any time.
Possible themes: 
Endemic or Native to Montana zone
Invasive or Non‑Native zone
Species Cards Patrons Can Move Around
Laminated species cards show clear pictures of animals, plants, insects, or fungi found in Montana. Patrons pick up a card, read about the species, and place it in the category they think fits best.
Considerations for your cards: 
A large species photo on each
A common name without indicating which category it belongs to
A QR code linking to the iNaturalist species profile
Patrons scan the QR code to read the iNaturalist information and decide whether the species is native or invasive based on the profile.
iNaturalist shows native range and invasive status
Species pages display real Montana observations
Patrons adjust their placement based on what they learn

Rotating Species Sets
You can rotate species cards every season or whenever staff have time. This keeps the wall fresh, engaging, and relevant throughout the year.

You might consider: 
Spring: wildflowers and invasive weeds
Summer: pollinators and invasive beetles
Fall: shrubs and invasive grasses
Winter: birds and invasive starlings or sparrows
Tie it in to Community Science
Add a small sign inviting patrons to explore real sightings or upload their own observations. This ties the wall directly into community science without adding work for staff.
Consider prompts on the sign like:
A QR code saying 'See if this species has been observed in your location"
A prompt encouraging patrons to add their own observations to iNaturalist
