Potentilla plot soil moisture for Cabin Clearing, Elk Meadows and Rainbow Meadows, 2019.

To understand parent-hybrid dynamics in cinquefoil (Potentilla) species in the Colorado Rocky Mountains, I am estimating environmental overlap among parents and hybrids, interbreeding among parents and hybrids, and hybrid population growth in multiple natural populations at NWT and (not included here) the Rocky Mountain Biological Laboratory (RMBL). Since 2018, I have been monitoring populations at Rainbow Meadows Lower, Rainbow Meadows Upper, Elk Meadows South, and Cabin Clearing - sites that vary in cinquefoil composition. In 2019, my team and I recorded reproductive phenophases (e.g., vegetative, buds, flowering, setting seed) on tagged plants in June, July, and August. When plants began flowering, we estimated floral counts. Characterizing flowering phenology of parent and hybrid species in each site sheds light on the potential for ongoing interbreeding in different environments. NWT soil moisture are provided here, demographic and phenological data are shared separately. This data was collected to test broad hypotheses about hybrid-parent dynamics in changing montane environments.
