A well-documented indicator of climate change effecting the ecosystems is flowering times of plants. Earlier flowering times have resulted from the changing climate and one of the species affected by this phenomenon are cranberries, Vaccinium macrocarpon, native to Massachusetts. The increase in global temperature has changed the phenology of this species which has left it vulnerable. This has major implications to cultivators of cranberries whom have been largely used to sustain a growing population of people. This change in phenology can be seen using the documented times of cultivators spraying flowering cranberry bud with fungicides. Ultimately, cranberry flowering times is a well-documented event that casts insight on how climate change can affect flower phenology and crop yield of a major food source in the North Eastern United States.
