Backyard Habitat Certification Story

Testimonial from Monica Delzeit

Rachel Carson saw it coming 60 years ago. As a medical professional, I see our number one public health concern as the climate crisis. No other public health concern will affect us all. After retiring, I felt that I could add to my love of gardening and include all the portions of the Backyard Habitat Certification Program. Despite my orthopedic issues, I’ve been able to introduce and maintain all 5 pillars of this program, without much outside help:

  1. Native plants and trees house and feed the native insects, birds and mammals that co-evolved with them over geologic time. Co-evolving means just the right color, sugar composition, height, etc. attracts hundreds of species instead of just a handful with non-native plants and trees.
  2. Noxious weeds have no native predators to keep their growth and spread controlled. In this way, they reduce biodiversity of native plants and, in turn, the native insects, birds, and mammals that rely on native plants for housing and forage. I want to see more of our charismatic fauna, not less.
  3. Pesticides/Herbicides/Fertilizers are primarily made in a lab and get into the ground water and bodies of water, adversely affecting native water life and us. Native plants and trees don’t require these chemicals. Our natural environment is all they need.
  4. Stormwater washing over our roofs, driveways, sidewalks and roadways picks up pollutants like your neighbors pesticides/herbicides, motor oil and gasoline, metals and other chemicals. These drain into our beautiful rivers and streams, endangering water quality and wildlife. The program encourages nine possible management actions.
  5. The newest piece to me is wildlife stewardship. This can include keeping cats indoors; keeping a water feature clean for birds, insects and amphibians; nurturing mason bees; putting in a pollinator meadow (if you have a large enough property); leaving leaves, snags and nurse logs; reducing outdoor lighting during bird migration; to name a few.

I so enjoyed the sense of community and common sensibilities this program created that I became a certification volunteer in 2021. I’m heartened by the commitment of so many new friends to stewarding out beautiful temperate rain forest in Lake Oswego, and beyond. It gives me hope.

Good news! The program has recently caught up on enrolling interested new participants in Lake Oswego.

The Humble Habitat Re-Wilding Project

Testimonial from Mark & Leah Puhlman

We’ve always loved a project.  When we moved to the Portland Metro area, our housing search brought us to a bank-owned rancher style home on half an acre in Lake Oswego. As you can see from the pictures, we had our work cut out for us.

We quickly learned transforming a neglected, blackberry and ivy infested half acre is a marathon, not a sprint. We started slow and are still working toward our vision 11 years after we purchased the home. 

When we purchased the property there were some rhododendrons and azaleas, a couple of Douglas fir trees, and we were thrilled to find a flourishing Madrone. And lawn. So much lawn. Most of the three sides of the property were lined with six foot high, 12 foot wide hedges of Himalayan blackberry. 


Together, we set out to transform the property into something that was sustainable, friendly to both insect and animal life, and beautiful. Our goals included:

  1. Low maintenance
  2. Areas for outdoor relaxation
  3. A vegetable garden
  4. Plants and features that supported pollinators and birds
  5. Decreased lawn.

Our first task was to rid the property of invasive plant life. The most prevalent species was the Himalayan blackberry but there was also ample English ivy and Creeping buttercup to remove as well. As you can see from the pictures, sometimes the blackberry won and sometimes we won.

Battling Blackberries

To remove most of the blackberries took three years. However, the removal of invasives is never a one and done assignment. After eleven years, we are still pulling blackberry and ivy found under bushes and in the planting areas. 

When we retired Leah became a Master Gardener and Mark joined the Lake Oswego Sustainability Network and the Lake Oswego Sustainability Advisory Board. Many of the plants we chose in the first few years were just what was available at local nurseries and big box stores.  When we started going for Backyard Habitat certification, we learned so much and found great resources for native plants.  We are still removing our unfortunate choices and replacing them with keystone native plants whenever possible. 

Trees are a central element of the garden. Collaborative decision making regarding the tree selection was vital to matrimonial harmony as well as ecologically appropriate decisions. We have removed an invasive Norway Maple that we planted early on and have replaced a dying, non-native birch tree with a Big Leaf Maple – a keystone plant that supports a vast array of pollinators. Up next is removing a Bradford Pear, another invasive species, with native Bitter Cherry, Prunus emarginata, another keystone tree. 

We continually learn more and as we do, we change our decisions and behaviors. The lawn has shrunk to a fraction of its previous size and provides a pathway through the garden and a racecourse for the dogs.  We have added a large water feature,  routed two downspouts into bioswales, and we have a rain garden in the back yard.  As we fill in the bare spots with easy care, drought tolerant natives, the landscape is becoming less work, uses less water, and provides pleasant habitat for humans and creatures alike. 

We have gold certification in the EcoHome LO program for Lake Oswego. We have a Silver certification from the Backyard Habitat program and should receive platinum status upon recertification.  We are a National Wildlife Federation certified habitat garden, and we are registered in The Home-Grown National Park movement as described in the Douglas Tallamy book “Nature’s Best Hope.” Leah used this book as a guide for her recent Garden Wilding webinar for the Master Gardener program. Every plant purchased these days gets weighed on the scale of the wildlife it will support.

Our “Humble Habitat” garden is a work in progress.  We are learning that each yard can be a powerful tool to protect biodiversity for our rapidly dwindling wildlife. There is no better feeling than to walk out in a yard that is teeming with life, brings joy to the observer, and restores a natural balance to our small piece of the world.
