Mule Deer of the Verdugo Woodlands

Humans and deer have lived alongside each other for a long time. In the past, this relationship has been mutually beneficial. Native Californians would routinely carry out small controlled burns to clear underbrush and prepare pastures, which created fresh new growth that deer love to eat. In 1907, the first law to protect deer was introduced in response to the increased interaction between deer and California’s growing population. Laws protecting natural predators such as bears, mountain lions, and wolves took a long time to follow (the endangered species act did not protect bears until 1970), a factor that allowed deer numbers to increase.

Over time, the number of deer that reside in the Wildland Urban Interface (WUI), “the zone of transition between unoccupied land and human development,”(1) and some residential environments has increased. This is perhaps the result of a combination of factors such as; a reduced number of natural predators, the increasing population that lives in or near the WUI, and increased availability of food in well-irrigated environments such as gardens.

As a result, deer have increasingly adapted to live in urbanized environments, and a common issue that arises from living alongside deer is damage to trees and gardens. Deer love to graze on fresh shoots and leafy green plants, which can stunt the growth of young trees and disrupt fruit production. Plants that deer find “highly palatable,” such as roses, apple trees, and members of the Malvaceae family, such as mallow, hibiscus, and abutilon, are also commonly found in domestic gardens.

The Verdugo mountains are a beautiful and unique example of the Wildland Urban Interface within Los Angeles. This small mountain range is surrounded by urban development, leaving an isolated pocket of nature within the city. “You have what is almost like a federally protected forest that has survived human urban growth all around it. It’s like an undiscovered Atlantis.”(2) Some neighborhoods that touch the Verdugo mountains include Glendale, Whiting Woods, Oakmont, La Crescenta Highlands, Pasadena, and Altadena. The people who visit and reside here consider it a privilege to live in this unique area where an almost undisturbed natural environment meets the city.

As a Certified California Naturalist, Sarah loves exploring the hiking trails in and around the Verdugo mountains. This area is teeming with wildlife “except for the absence of grizzly bears, the wildlife in the Verdugos is much as it was 200 years ago.”(3) California has six subspecies of mule deer (Odocoileus hemionus), The California mule deer (Odocoileus hemionus californicus) is commonly found in the Verdugos and surrounding areas.

One way we can live alongside deer and maintain a beautiful garden is by planting deer-resistant plants, many of which also make a beautiful aesthetic or fragrant addition to our garden. While no plant is one hundred percent deer-proof, there are some qualities of certain vegetation that deer tend to avoid.
Golden Currant (Ribes Aureum)
Prickly or furry plants are a good place to start. Some examples include the Fuchsia flowered gooseberry (Ribes speciosum) and the California barberry (Berberis pinnata). The California barberry’s (Berberis pinnata) prickly leaves make it unpleasant to eat, but it also has beautiful yellow flowers, making it an appealing garden plant. The Fuchsia flowered gooseberry (Ribes speciosum) has gorgeous bright red dangling flowers that also attract hummingbirds to your garden.
Cleveland sage (Salvia clevelandii)
Deer also tend to avoid aromatic plants such as Sages (Salvia sp), Cleveland sage (Salvia clevelandii), and Hummingbird sage (Salvia spathacea) have a beautiful smell that deers dislike.
Tough and leathery plants can be hard for deer to chew. The California bush anemone (Carpenteria californica), a shrub with beautiful white flowers, and the Big berry manzanita (Arctostaphylos glauca) have tough trunks. Ground cover such as Emerald Carpet (A. uva-ursi X nummularia) is a leathery plant that grows densely on the ground, which can also reduce weeds.
California Poppies (Eschscholzia californica)
Fast-growing plants such as the California wild grape (Vitis californica) are a good option, as their rapid rate of growth allows them to recover from being grazed on as they grow out of reach from the deer. Spring wildflowers are also a good option as there are so many of them; even if a few are eaten in amongst all the new growth of the season, plenty still survive to make a beautiful garden.

If all else fails, a deer repellent spray can be applied to the plants in your garden. This non-toxic spray (which won’t hurt the deer or the plant) leaves a bad taste in their mouth, which is intended to slow grazing. There is a variety of homemade and store-bought options available.

Taking all of this into account, the remaining wildlife on Earth is a fraction of what it once was, “Extinctions have been a natural part of the planet’s evolutionary history. 99% of the four billion species that have evolved on Earth are now gone.”(4) We treasure day-to-day encounters with the wildlife that remain. Living amongst wildlife in the Wildland Urban Interface is a unique privilege; taking a break from the city and enjoying a hike in this pocket of nature is a wonderful gift. Being mindful of the wildlife in the Verdugo mountains can take the form of gently suggesting not to eat the plants in your garden (through plant choice or other options) or leaving a bowl of water out on hot summer days . This is a rewarding part of the experience of living and visiting here; in return, we get to live alongside these magical animals and watch them thrive.
