Each plant species in a region is assigned a coefficient of conservatism, also known as a C-value, ranging between 0 and 10. A plant species with a higher score (e.g. 10) has a lower tolerance to environmental degradation such as overgrazing or development and therefore is naturally restricted to undisturbed, remnant habitats. Non-native plants are either assigned a C-value of 0 or are … WebOHIO FLORISTIC QUALITY ASSESSMENT INDEX Coefficients of conservatism (CC) assigned to each species by Andreas et al. (2002). The CC, with values ranging from 0 to 10, is an estimate of the degree to which a species is associated with high-quality natural communities similar to those which existed in pre-settlement times.
