Pssst… Ever wonder about the habitat restoration projects that our contract-grown plants are being used for? Read to the bottom of this newsletter for our first ever newsletter project highlight!

Greetings,

Flowers are bursting with color around the nursery thanks to the spring sunshine we’ve gotten over the last few weeks in between the rains. As our plants come to life with showy blooms in the sun we’ve noticed more and more bird visitors by the day! Sometimes birds can be quite pesky in the nursery during ‘bird season,’ taking every opportunity to chomp at our tender baby plants (especially the annuals and grasses).

Although the little buggers can be pests at times, we still have a great appreciation for them since birds are not only beautiful to observe, but they are incredibly valuable members of many of our habitats across California!

This month’s newsletter is dedicated to the birds and the things we can do to make our gardens more friendly and habitable places for them to thrive alongside us 🙂

Birds are considered “ecosystem indicators” – the healthier an ecosystem is, the more species of birds it will support. Here in California we are lucky enough to exist along the Pacific Flyway, with about 700 species of birds that have been observed throughout the state (check out the common species seen around the Bay Area here: https://www.inaturalist.org/guides/1262). Many of these bird species have coevolved with our native plants for thousands of years, which means that our native plants are particularly well suited to providing them the fundamental elements that these birds need to survive and thrive in our changing climate. What are these fundamental elements, you ask? Much like us, it boils down to water, food, and shelter for the birds.

Water sources: fountains and birdbaths

The sound of moving water attracts birds for drinking, bathing, and fun!
Birds prefer shallow, flat dishes over deep water.
Note: it is critical to keep bird baths clean since dirty bird baths can spread disease and carry contaminants that can make the birds sick. If you have a bird bath, replace the water daily and sterilize once a month!

A variety of food sources (Fruit, seeds, insects, caterpillars and worms)

Seeds are a significant part of the diet of many adult birds. It can be tempting to ‘clean up’ your plants right after their blooms are spent, but it’s important to allow your plants to go to seed so the birds can make the most of that food source! A garden with many native annuals and perennials that seed at different times will provide ample food for much of the year.
Fruiting plants like our native redberries (Rhamnus spp.) and cherries (Prunus spp.) are particularly important food sources for birds in winter when other food sources are scarce. The bright red color of many of our native berries entice the birds and allow them to conserve energy while foraging since the berries are easier to spot.
Plants that support insects are also super important for healthy bird habitats. Although many adult birds primarily eat fruit, leaves, and seeds, their young eat mostly caterpillars and worms as they grow. They need a good variety and quantity of larvae and worms available, since baby birds need to be fed every 10-20 minutes or so while they are growing!

Shelter and cover

Birds need a variety of protective spaces to escape from danger, nest, and bring up their young.
Shrubs are great because they often form thickets that provide excellent cover.
A mix of shrubs and groundcovers is best for providing plenty of perches and nesting sites for both flying and ground-nesting birds.

With all this in mind, below are some of our best recommended plants to make your garden more bird-friendly this season!

Chia

Salvia columbariae

Upright, sun-loving annual that grows to about 1.5 feet tall

Common sunflower is fast-growing annual herb that can grow up to 9 feet tall.
Harvest the seeds in late fall or let it self-sow to start a new crop for next year.

Its showy ray petals attract hummingbirds and butterflies, which are rewarded with a high probability of finding nectar in the numerous disc flowers.
These sunflowers also attract beneficial insects as a larval host plant, and provide fabulous habitat for nesting birds as well as a bounty of seeds that are a favorite among finches and sparrows!

Purple Sage

Spiny Redberry

Rhamnus crocea

Available in D40 pots for $9.90 each!

Tough, adaptable shrub that grows 5 ft. x 5 ft.

Named for the hundreds of pea-sized, cherry red berries that appear in late spring to the delight of birds
Grows best in full sun to part shade on dry slopes
Note: only female plants produce fruit; we grow them from seed, so no we don’t know which plants are female Best get 2-3 to increase your chances of having a female plant with a male plant neighbor for pollination!

Hollyleaf Redberry

Rhamnus ilicifolia

Available in D40 pots for $9.90 and D16 pots for $8.50 each!

Fast growing, handsome, evergreen shrub, often treelike, grows to 15 ft. tall

Hollyleaf Cherry

Prunus ilicifolia

Showy and easily grown from seed, Hollyleaf Cherry is prized for cultivation and has been used as a food source for hundreds of years for both birds and people!
The cherries are edible, but have much less flesh than cherries from the grocery stores. If they are not to your tase, more to go around for the birds 😉

Project Highlight: Three Creeks Parkway Restoration Project

From 2020-2022 The Watershed Nursery (TWN) had the great pleasure of working with American Rivers and landscape architects at Restoration Design Group on the Three Creeks Parkway Restoration Project on Marsh Creek in Brentwood, California.

The project was a combined effort between the non-profit group American Rivers and the Contra Costa County Flood Control District to convert nearly a mile of bare, trapezoidal flood control channel into a thriving creek full of native trees and plants, birds, salmon, and other wildlife. TWN conducted site-specific seed collection, propagated and delivered ~ 13,000 watershed specific riparian species for the project. The Triangle Properties team installed the plants with loving care and have been tending them since. The Marsh Creek Regional Trail parallels the project allowing the public to enjoy a natural landscape right in the heart of Brentwood.
