Impacts of insect herbivores on rare plant populations

Any effect of herbivory on vital rates such as survivorship or fecundity, if transduced into an effect on population size or growth rate, could drive a rare plant to extinct ...

Habitat conservation
Habitat conservation is a land management practice that seeks to conserve, protect and restore habitat areas for wild plants and animals, especially conservation reliant species, and prevent their extinction, fragmentation or reduction in range. It is a priority of many groups that cannot be easily characterized in terms of any one ideology.
