Homegrown ParksWHAT is it?

Homegrown National Park is an effort to encourage the planting of native species in existing gardens, farms and forests to support the biodiversity of life that is under threat. The goal of HNP is to replace one-half of all lawns in the U.S. (20 million acres!) with native plantings.

WHY is it important?

More than a quarter of our bird life (2.9 million birds) has been lost since 1970, insects are in decline and a quarter of all North American bumblebee species are at risk of extinction.  Reasons are many, but a major cause is the widespread loss of the native plant species these populations depend on. For example, birds depend on a healthy supply of insects and caterpillars to raise their young, and non-native “insect-resistant” species provide them with little to no sustenance.  If we continue this trajectory, we will ultimately lose the life support system that nature provides humans.

Doug Tallamy, PhD., the author of Nature’s Best Hope, has spent a lifetime studying the relationships between wildlife and native plants.   Based on that understanding he offers us a way to reverse course.   He has turned his idea into a national movement called Homegrown National Park. This concept extends the idea of “parks” into our yards and communities by incorporating native species, minimizing pesticides, and removing invasive species; thereby creating “ribbons” of connected habitat in our own neighborhoods.

HOW do I get started?

Get on the Map!  The HNP brochure outlines the steps we can take that will make a difference. These are universal principles; however, #3- “Planting the plants that do the most good” requires identifying plants native to the Willamette Valley.

Keystone species are the native plants that host the greatest variety of moth and butterfly caterpillars in a given area. The National Wildlife Federation has created a database that ranks plant genera in every U.S. county based upon this criteria (www.nwf.org/NativePlantFinder). According to Tallamy, if your yard lacks keystone species, the food web you are trying to build may fail.  Start with a few keystone trees and shrubs, adapted to your growing conditions, and fill in with pollinator plants that attract the most native pollinator species.
