These apples represent cultivars (i.e. culinary experiences, history, and flavors) currently absent from the commercial apple market.

These trees contain precious genetic diversity that offers resilience to stressors like pests, disease, and climate change, and insight into adaptation.

This project breaks down the notion of science as a solitary, academic endeavor and helps students see how collaborative and community-centered science can be.

This project engages our Colorado community, celebrates local wisdom, and offers an entry point for those interested in academic culture and research.

There are lots of ways to get involved with the project:

tell us about an apple or crabapple tree

We would love your help in learning more about the apple trees in Boulder! If you have an apple or crabapple tree in your yard or know of one on public property, please submit the tree on our student created data collection app! We are interested in the physical tree features as well as any stories you may know about it.

Not sure if it’s an apple tree, use this handy guide to find out. If you would rather report a tree location without using the data collection app, please report trees here!

help with apple tree surveys

Get Involved! Help the BATP to locate, measure, and document the apple trees near you using the BATP Collect App. The easiest way to stay current on volunteer opportunities is to join our email list, where we send quarterly updates on our events and activities:

COLLECT Data with our mobile App!

Identifying cultivars is the first step to understanding the diversity of apple trees we have in Boulder and will allow us to explore research questions about how differences in the local environment and climate change may affect these historical trees in our community. You can add data through our mobile app or with our paper sampling protocol.

discover the history

If you have a story you’d like to share or if you want to put your curiosity about Boulder apple trees to work, volunteer to be a part of the history team! Share stories, conduct oral histories, dive into the archives, support or host a community history event, and more.

Your donation will directly support our research, education, and outreach efforts. Any amount will help us continue doing our important work to restore Boulder’s apple heritage.
