Editor’s note: This is the third and final installment in a series about creating a bird-friendly yard. In the two previous blog articles, Wendy Diaz, EMGV, wrote about pivotal moments in her life as a gardener: deciding to focus on native plants, and creating a plan based on plant recommendations from the National Audobon Society.

My plan to create a bird-friendly yard will be accomplished in two stages. Stage 1 is the removal of high-threat invasive species in the fall of this year (2018), and Stage 2 will commence in the spring of 2019 by removing non-natives that are not high threat but their native alternatives would provide more benefit for wildlife and not multiply as quickly.

My garden plan includes the following replacements based on recommendations from the New Hope Audubon Society, NC Botanical Garden and the Going Native Website^1,2,3:

Next time you are considering an ornamental plant to add to your landscape why not try a native plant that suits your needs and helps wildlife at the same time? At the very least, don’t plant invasive species like I did. Hopefully in time, I will attract new birds, butterflies and caterpillars. Then I will need a better camera lens to zoom in on all the new flowers and animals!
