Using a good old-fashioned fall cleanup to transform your yard into a sanctuary for wildlife is not only rewarding but also crucial for supporting the diverse ecosystems native to Oregon.
By intentionally managing your yard, you can create a habitat that benefits pollinators, birds, and other wildlife while maintaining an aesthetically pleasing landscape.
Here are five fall tips to help you keep your yard looking tidy, intentional, and welcoming for wildlife.
Leave the Leaves: The Power of Natural Mulch
One of the simplest and most effective ways to support wildlife in your yard is to leave the fallen leaves where they land. This practice, often called "leaving the leaves," creates a natural mulch layer that offers numerous benefits for wildlife and your garden.
How It Helps Wildlife
Leaves provide critical habitat for insects, including butterflies, moths, and beetles, which overwinter in the leaf litter. These insects are vital food sources for birds and other small animals.
By allowing the leaves to remain on the ground, you are essentially creating a winter shelter for these creatures. Additionally, as the leaves decompose, they enrich the soil with organic matter, promoting healthy plant growth in the spring.
How to Do it
Materials Needed: Rake (optional), patience.
Steps:
Identify areas where leaves naturally accumulate in your yard, such as under trees and shrubs.
Instead of bagging and removing the leaves, let them remain as a natural mulch layer. If you are trying to get rid of lawn or suppress weeds, cover the area with 6-12 inches of leaves.
Use leaves in other garden beds that may not get covered by natural leaf fall; lightly spread the leaves to cover the soil, creating a 2-3 inch thick mulch layer.
If you prefer a tidier look, rake excess leaves into a compost pile, use them in a bug snug, or use them to mulch around perennials and trees.
Why It Works
Leaving the leaves helps reduce the need for synthetic fertilizers and herbicides, promotes soil health, and creates a habitat for overwintering insects. This practice also supports the decline of lawn areas, which can be transformed into more diverse, wildlife-friendly spaces.
Overseed Your Lawn with A Native Wildflower Meadow Mix
Fall is the perfect time to overseed your lawn with native wildflower meadow mixes. This practice not only reduces the amount of lawn you need to maintain but also creates a vibrant and diverse habitat that supports a wide range of pollinators and other wildlife.
How to Do it
Materials Needed: Native wildflower seeds (specific to Oregon), mower, seed spreader, rake, water.
Steps:
Mow the site as low as possible in early fall with a bagging mower, or cut the field for hay, and remove the bagged clippings or hay bales to compost them away from the meadow. Overseed the area before significant grass re-growth occurs. Following the initial first-year seeding, you should perform active ongoing management of the meadow for best performance:
Actively watch for and remove aggressive weed invaders such as Canada thistle and blackberry. Mow the site as low as possible in early fall with a bagging mower, or cut the field for hay, and remove the bagged clippings or hay bales to compost them away from the meadow (composting will allow any viable insect eggs or larva to emerge).
Continue to overseed the meadow immediately after mowing every year if possible, or at least every few years. Consider adding yellow rattle at a rate of 1-2 packets per 100-sqft to further reduce grass vigor and increase wildflowers.
A Note on Expectations
Neglected and overgrown grassy areas may have decades of dormant viable grass and weed seed in the soil (hundreds of pounds per acre). Reintroducing native wildflowers into such spaces is a process, not a magic switch.
The more active weeding, annual mowing, and overseeding invested in such sites, the more success you will have. However, results can take several years to become increasingly visible.
Seed Mix Contents:
Annual Wildflowers: Farewell to Spring (Clarkia amoena), Spanish Clover (Acmispon americanus), Foothill Clover (Trifolium ciliolatum)
Perennial Wildflowers: Western Yarrow (Achillea millefolium), Great Camas (Camassia leichtlinii), Common Camas (Camassia quamash), Blue Eyed Grass (Sisyrinchium idahoensis), Big Leaf Lupine (Lupinus polyphyllus), Riverbank Lupine (Lupinus rivularis), Selfheal (Prunella vulgaris), Western Buttercup (Ranunculus occidentalis)
How It Helps Wildlife
Native wildflowers provide essential nectar and pollen for bees, butterflies, and other pollinators. As these insects thrive, they, in turn, support birds and other wildlife that rely on them for food. Native plants are also adapted to the local climate and soil conditions, requiring less water and no chemical inputs, which further benefits the environment.
Why It Works
Fall seeding takes advantage of the natural weather patterns in Oregon, including cooler temperatures and increased rainfall, which help seeds establish strong root systems before winter. By spring, you’ll have a lush, blooming meadow that requires less maintenance than a traditional lawn and provides critical habitat for pollinators.
Install Brush Piles: A Safe Haven for Small Wildlife
Create brush piles or bug snugs with fallen branches and leaves to give your yard a cleaner, more intentional look without sacrificing habitat.
Brush piles are an excellent way to provide shelter for various small wildlife, including birds, mammals, and reptiles. These piles mimic natural habitats, offering protection from predators and harsh weather conditions.
How It Helps Wildlife:
Brush piles offer hiding spots for small mammals like rabbits and chipmunks, as well as birds that seek shelter from predators. They also serve as bird nesting sites and provide a habitat for beneficial insects crucial for maintaining a balanced ecosystem.
How to Do it:
Materials Needed: Fallen branches, twigs, logs, and leaves.
Steps:
Gather fallen branches, twigs, and logs from around your yard.
Choose a quiet corner of your yard to build the brush pile, away from high-traffic areas.
Start by laying down larger logs as the base, then layer smaller branches and twigs on top.
Add leaves and other organic debris to fill in gaps and provide additional cover.
Maintain the pile by periodically adding more material as it decomposes.
Why It Works
Brush piles simulate the natural debris found on the forest floor, creating microhabitats that support a wide range of species. They also help recycle organic matter, enriching the soil and promoting plant growth.
4. Create a Pollinator Garden: Supporting Bees and Butterflies
Pollinator gardens are a targeted way to attract and support bees, butterflies, and other pollinators. By planting a variety of native flowering plants, you can ensure a continuous bloom throughout the growing season, providing a consistent food source for pollinators.
Pollinator gardens are a targeted way to attract and support bees, butterflies, and other pollinators. By planting a variety of native flowering plants, you can ensure a continuous bloom throughout the growing season, providing a consistent food source for pollinators.
How It Helps Wildlife
Pollinators play a critical role in the reproduction of many plants, including those that produce fruits and seeds that birds and other wildlife depend on. A pollinator garden also provides nectar and pollen, essential for the survival of bees and butterflies, many of which are experiencing population declines.
How to Do it:
Materials Needed: Native flowering plants (e.g., Oregon sunshine, western columbine, milkweed), wood chips, mulch, and garden tools.
Here are five Oregon native perennial wildflowers that bloom from May to October:
Oregon Sunshine (Eriophyllum lanatum)
Bloom Time: May - August
Description: This bright yellow wildflower is drought-tolerant and thrives in well-drained soils. It attracts pollinators like bees and butterflies and adds a sunny touch to your garden.
Western Columbine (Aquilegia formosa)
Bloom Time: May - July
Description: With its distinctive red and yellow flowers, Western Columbine is a favorite among hummingbirds and bees. It prefers moist, shaded areas and adds a splash of color to woodland gardens.
Showy Milkweed (Asclepias speciosa)
Bloom Time: June - September
Description: Known for its large, fragrant clusters of pink flowers, Showy Milkweed is vital for monarch butterflies as a larval host plant. It thrives in sunny, open areas and supports a wide range of pollinators.
Narrowleaf Fireweed (Chamaenerion angustifolium)
Bloom Time: July - September
Description: This tall wildflower produces spikes of vibrant pink-purple flowers that attract bees, butterflies, and hummingbirds. It’s well-suited to disturbed areas and can spread to create a colorful display.
Douglas Aster (Symphyotrichum subspicatum)
Bloom Time: August - October
Description: This late-blooming aster features lavender-blue flowers that are a magnet for pollinators, especially bees and butterflies. It grows well in a variety of conditions, from coastal to inland environments.
These wildflowers bloom continuously throughout the growing season, supporting local pollinators and adding beauty to your Oregon garden.
Steps:
Identify a sunny area in your yard where you can create the pollinator garden.
Prepare the soil by covering existing grass with 6+ inches of wood chips and add 2 in. of mulch to improve fertility.
Use a mix of native flowering plants that bloom at different times of the year to ensure a continuous food supply.
Plant in clusters to make it easier for pollinators to find and feed on the flowers.
Mulch around the plants to retain moisture and suppress weeds.
Why It Works
Native plants are adapted to the local environment and require less maintenance than non-native species. By providing a variety of flowering plants, you create a rich habitat that supports the entire pollinator lifecycle, from larval host plants to nectar sources for adults.
5. Build a Water Feature: Providing Essential Hydration
Adding a water feature to your yard is a great way to support wildlife. Water is essential for all living creatures, and by providing a clean, reliable water source, you can attract a wide range of wildlife, from birds to amphibians.
How It Helps Wildlife
Water features like birdbaths, ponds, or even shallow dishes of water offer a place for wildlife to drink, bathe, and cool off. Birds, in particular, rely on water sources for hydration and bathing, which helps them maintain their feathers in good condition. Amphibians like frogs and salamanders also depend on water for breeding and feeding.
How to Do it:
Materials Needed: Birdbath, shallow dish, or materials to build a pond (liner, rocks, plants).
Steps:
Choose the type of water feature that best suits your yard and the wildlife you wish to attract.
If using a birdbath or shallow dish, place it in a shady area and keep it filled with fresh water.
If building a pond, choose a site with partial shade and dig a hole to the desired size.
Line the pond with a waterproof liner and add rocks, plants, and other natural materials to create a varied habitat.
Maintain the water feature by keeping it clean and free of algae.
Why It Works
Water features create a focal point in your yard that attracts a wide range of wildlife. Birds, mammals, and insects all benefit from having access to clean water, and a well-maintained water feature can significantly increase the biodiversity of your yard.
A Low Maintenance, Habitat Packed Yard
Transforming your yard into a wildlife haven is both a rewarding and essential practice, especially in the fall. By following these five tips—leaving the leaves, overseeding with native wildflowers, installing brush piles, creating a pollinator garden, and building a water feature—you can create a more intentional and wildlife-friendly landscape.
Each of these tasks not only supports the local ecosystem but also helps maintain the beauty and functionality of your yard.
Remember, the key to a successful wildlife garden is diversity. By incorporating a variety of native plants and natural features, you create a balanced ecosystem that supports a wide range of species, from pollinators to birds and beyond.
