Challenge
Are wildflowers on Mount Rainier flowering earlier in warmer years? Test whether peak-flowering date shifts with snowmelt or temperature across 2013-2019.
- Where to start
- Load the observations CSV. For one or two species, estimate the peak-flowering date per year, then relate it to the year or to any climate field present.
- What to share
- A plot of flowering date vs. year (or temperature) and a statement on whether the shift is detectable.
