The Capitol Lake
Interpretive Center is a verdant refuge for wildlife. Its extensive palette of native trees and
shrubs provide a bounty of food and shelter for many creatures.
Native plants create healthy ecosystems. Indigenous insects have evolved to eat plant leaves of a certain chemical composition – namely, those provided by endemic flora. In other words, local insects have evolved to eat local plants.
By definition,
native insects have shared little or no evolutionary history with alien
plants…, and they thus are not likely to possess the adaptations required for
using these plants as nutritional hosts. Consequently, the solar energy
harnessed by alien plants is believed to be largely unavailable to native
insect(s)…- at least until they evolve the behaviors and physiology necessary
to eat them – and therefore unavailable to all animals that include these
insects in their diets.

In addition to
their chemically-compatible leaves, native plants offer up a wide
buffet of flowers, fruits and seeds throughout the year. Their branches host bark-dwelling insects,
and their leafy ground detritus hides countless worms, grubs and other critters
that birds and small mammals love to scavenge and eat.
For human users
of the CLIC, native plants bestow a subtle beauty to the eye, and the
opportunity to observe animals “at home” in their natural setting.
