Keystone Plants by Ecoregion - National Wildlife Federation

The research of entomologist Dr. Doug Tallamy and his team at the University of Delaware have identified 14% of native plants (the keystones) support 90% of butterfly and moth (Lepidoptera) species. The research of horticulturist Jarrod Fowler has shown that 15% to 60% of North American native bee species are pollen specialists who only eat pollen from 40% of native plants.

Keystone species - Wikipedia

For example, the herbivorous weevil Euhrychiopsis lecontei is thought to have keystone effects on aquatic plant diversity by foraging on nuisance Eurasian watermilfoil in North American waters. Similarly, the wasp species Agelaia vicina has been labeled a keystone species for its unparalleled nest size, colony size, and high rate of brood production. The diversity of its prey and the quantity necessary to sustain its high rate of growth have a direct impact on other species around it.

Keystone Species - an overview | ScienceDirect Topics

The loss of a keystone species will produce a cascade of effects on the diversity and function of the remainder of the ecosystem (Bond, 1993). Consequently, since keystone species can control ecosystem diversity and associated ecosystem functions, they and the habitats they live in often receive high priority in conservation management plans.
