Keystone Plants – Essential Pillars of Biodiversity
Some native plants support far more than their simple presence would suggest. Known as keystone plants, they provide foliage, pollen, or nectar to a multitude of insects, including caterpillars, which are an indispensable resource for many insect-eating birds.
Research by entomologist Douglas Tallamy shows that only about 5 percent of native plant genera can, on their own, support 70 to 75 percent of local caterpillar species. These caterpillars form a crucial food base for birds, bats, and other insectivores. As a result, just a few well-chosen plants can significantly strengthen the biodiversity of a garden.
The concept is inspired by architecture: just as the central stone of an arch supports the entire structure, keystone plants stabilize ecological networks. Where they are missing, the diversity and abundance of insects decline, weakening the entire food chain.
Planting these species in a garden, on a balcony, or in a landscape is a concrete action that supports pollinators, birds, and the resilience of local ecosystems. A small effort, but an immense impact for nature !
