Small plots of native plants in urban areas have been shown to significantly boost insect species diversity, highlighting the potential for even small-scale efforts to make a difference to our ecosystems (Tallamy, 2020).

About our Project
LAHR GARDEN is a small ecology project in Barrington, IL. Named for our kiddos - L-Lennon, A-Agnese, H-Herman; and our last name, R-Ross. Nature and science is the family. Grandma Wendy, a naturalist, grew a prairie at their Barrington Hills home (where the kids are beginning our project from seed), and Nonna Nancy is a former science teacher. Mom Christine, is an artist with a background in garden design from the Regenstein School at the Chicago Botanic Garden/University of Illinois Extension Master Gardener Alumnus.
Why native plants? For us, 1) current research: It takes time - long evolutionary time - for insects to adapt (due to leaf chemistry). If energy from non-native plants is not available for native bugs, it is also unavailable for animals that eat those bugs (Tallamy, 2008, 2018). 2) experience: watching Grandma Wendy's prairie come to life to bring a bald eagle - yes a bald eagle! to their home.
As with most things, there are exceptions. We have some cultivars (and hope to do comparitive studies!); and heritage plants (great-great-aunt Nadine's peonies). And there are some (though not signficant) bugs that can use non-native plants (like parsley, part of the carrot family) there is just so much still to be studied. At bigger nurseries, native plants sections are growing, but finding all straight species can be a challenge for homeowners -- with the LAHR GARDEN project, we are hoping to bring the ease ordering online & pick-up to local families in our community.

Native insects are specialists. Evolving alongside plants (Kennedy & Southwood, 1984), they do not eat non-native. Declining native and increasing non-native species in landscapes directly affects insect populations; which, then impacts birds/other wildlife Tallamy, 2008).
-
96% of terrestrial birds feed their young arthropods (caterpillars) making native plants crucial for survival (Tallamay, 2008). Less native species makes an ecosystem less diverse. Biodiversity is essential to stability of ecosystems; impacting oxygen, water efficiency (Kinzig, 2002).
-
Invasive non-native species also outcompete natives (being away from natural competitors) for light, water, nutrients and do not support the ecosystem community. This can displace plants and animals that have critical roles in ecosystems and again threaten biodiversity (Tallamy, 2008).
