Assessment of Iris versicolor L. population health across northern Michigan

Abstract: 
Sixty eight (68) distinct localities of Iris versicolor L. populations previously catalogued by the University of Michigan Herbarium will be visited over the course of the plant& flowering period (late May-July) to assess the current state of each population. Factors investigated will include the presence or absence of the population, the health of the population (assessed via water and soil analyses, population size and density estimates for I. versicolor, identification of other taxa inhabiting the same area, light/shade ratio estimates, and assessments of human impact since the initial cataloguing of the population) if present, and potential causes of extirpation if absent. The goals of the study are twofold: 1) assess how human activities (land development, introduction of new organismal species, global climate warming) may have affected previously recorded plant populations, and 2) update Herbarium records with taxa location data as well as approximations of the health of populations, nearby settlements, and interesting notes about each locality.
