The Environmental Leadership team collected phenological data for 12 native grass and forb species native to different latitudinal ranges (Table 1). To determine changes in species range and rate of survival outside of native zones, all species were planted at all three sites (Image 1). 

Table 1 includes all species studied throughout the project. During 2016-2018, student teams studied the effects of climate manipulation on 12-15 species. The 2018 focal species are indicated with an asterisk.
