Firesafe Landscaping – Part I

With the recent heat wave and the fires burning now in Southern California I’m reminded of our vulnerability to wildfires. The Martin Fire of 2008 and the Lockheed fire of 2009 together burned over 8,000 acres. I often hike in Bonny Doon Ecological Reserve and live close-by where these fires occurred. There’s a large, burned manzanita along the trail that serves as a grim reminder of the devastation that wildfire left in it’s wake. The skeleton-like manzanita, ponderosa pine and many other plants are regrowing from seed left in the soil. The fire was so hot it killed even the plant crowns preventing many of them from re-sprouting. I’ve been monitoring the regrowth for years and it’s progressing nicely but you don’t want this to happen to your property. Is there a landscape that is safer in a wildfire than another? Which plants burn more readily?

Many people think they have to clear everything within 30 feet of their house to truly have a defensible space. This is unnecessary and actually unacceptable due to soil erosion and habitat destruction reasons. We want to retain the character of this beautiful area we live in, provide the food and shelter that our native wildlife are accustomed to but also reduce fire risk. For example, grasslands mowed to leave 4-6″ of height allow insects, reptiles, amphibians, and small mammals shelter, food and a place to reproduce. Leaving 4-6″ standing also provides some erosion protection and shades out some of the weeds that follow disturbance.

Fire safe landscaping is a term used to describe defensible space. It can look like a traditional landscape. The idea is to surround the home with things less likely to burn and place them to provide separation between canopies and avoid creating fire ladders. Highly flammable plants should be placed, whenever possible, with low-growing and/or low fuel plants.

Many homes may not have 30 ft. between their house and the property line but following these guidelines will help. Plants in this area need to be the slowest to ignite and should produce the least amount of heat if they do burn. There are plants with some fire resistance which include drought tolerant California natives and Mediterranean climate selections. The key to fire resistance, though, is maintenance and keeping the moisture in the foliage high.

For example, Baccharis pilularis or dwarf coyote brush is generally considered highly flammable if its lush green top growth covers a hazardous tangle of dry branches and leaves several feet high. Trim this plant down low in early spring, remove the dry undergrowth, follow with a light feeding and watering and the new top growth is now resistant to fire.

Other considerations may be as important such as appearance, ability to hold the soil in place and wildlife habitat value. Some fire-resistant California friendly plants are western redbud, monkey flower, ceanothus, sage, yarrow, lavender, toyon, California fuchsia and wild strawberry. Also consider coffeeberry, flowering currant, bush anemone, snowberry, California wax myrtle and evergreen currant. Fire resistant plants from areas include rockrose, strawberry tree, Chinese pistache, barberry, escallonia, oleander, pittosporum, bush morning glory and wisteria to name just a few.

Keep your landscaping firesafe to protect your home.

A Thanksgiving Poem

Thanksgiving-table-arrangementA Thanksgiving Poem

by Jan Nelson, The Mountain Gardener

Once upon a time when our area was under water
there were no parks or trails or trees or gardens.
I’m thankful that our mountains rose from an ancient ocean
so we could enjoy this beautiful place we call home.

I’m thankful for the Bigleaf maples
that shower me with leaves as big as saucers
as I walk in Henry Cowell along the River Trail
and for the giant redwoods that sprouted long ago
at the time of the Mayan civilization.

I’m thankful for the Five-fingered ferns that grow lush along Fall Creek
on the way to the old lime kilns
and for the canyons, hiking trails and small waterfalls
that feed the year-round creeks.

I’m thankful for the sweet music of the violist
who practices inside the Felton Covered Bridge
and for the sound of children laughing as they play in the park.

I’m thankful for the pond and western turtles who live at Quail Hollow
and for the unique sandhills, grasslands and redwoods, too,
and for the plants and other small creatures that live only there.

I’m thankful for the dog park and soccer field at Skypark
where little kids and dogs both big and small have a place of their own
and for the picnic area and Fourth of July fireworks,
and for the Art and Wine festival and Music in the Park on summer nights.

I’m thankful for Bonny Doon where I can see both the Pacific and San Lorenzo Valley
and for the Ecological Reserve which is growing back nicely after the Martin Fire,
and for the fossilized marine animals and sharks teeth
that are exposed in the mountain made of sand.

I’m thankful for California’s oldest state park. Big Basin, with its waterfalls and lush canyons
and slopes covered with redwoods sorrel, violets, fragrant azaleas, mountain iris
and for the salamanders, banana slugs, marbled murrelets
and red-legged frogs who make it their home.

I’m thankful for the whisper of the wind blowing across the water at Loch Lomond
and for the gentle whir of fishing reels most years at the edge
of thick tanoaks, redwoods and madrone.

And finally, I’m thankful for friends and family and neighbors who share all this with me.
I wish you all a Happy Thanksgiving.

Bonny Doon Ecological Reserve 2014

peak_rush_roseI hike in the Bonny Doon Ecological reserve quite often but had never seen the waterfall. Since the Martin fire in 2008 I have written several columns about the remarkable comeback nature can make after a natural catastrophe. Each spring I eagerly await the new growth of manzanita, chinquapin, pine and the spring flower display. Recently I joined a group led by botanist and revegetation specialist Val Haley, who has been a volunteer at the reserve since 1993 and knows just about everything there is to know about this unique place on the planet.

During the Miocene Epoch which started about 23 million years ago and lasted until 5 million years ago, the global climate warmed. Plant studies show that by the end of this period 95% of modern plant families that reproduce by seeds existed. The soils in the reserve are a marine sediment and sandstone from an ancient sea that once encompassed California’s Central Valley. As the Santa Cruz Mountains were uplifted, the seabed and shoreline terraces were exposed and are known as the Santa Cruz Sandhills. This soil, called Zayante, is almost 90% sand and contains little organic matter. The Sandhills in Bonny Doon and other spots in our county are found no where else on earth.

On a beautiful Saturday afternoon, Val was excited to share her knowledge of silver_bush_lupinethe rare and endangered plants that have adapted to the sandhills. We enjoyed observing acorn woodpeckers visiting their granary in a Ponderosa pine and the bushtits eagerly eating manzanita berries. Along the trails we identified scat from some of the resident animals like coyote but didn’t see any evidence of Santa Cruz kangaroo rat. But it was the remarkable regrowth of the manzanita and pine and of the colorful wildflowers that got most of our attention.

There are several manzanita species living in the reserve and each has a different strategy of reproduction. Standing near a large burned out Silverleaf manzanita specimen, Val told us that this variety spreads its seeds outward from the trunk and with the heat of the Martin fire have sprouted in impressive numbers. Other varieties like the Brittleleaf manzanita are crown spouters and have regrown from their base. These new shoots are bigger and more vigorous than the seed spouters. Later we sought the shade of a live 20 ft Silverleaf manzanita. With a trunk of 12″ in diameter, Val estimated that this tree was about 200 years old. “They get much larger up here than at Quail Hollow”. she said. “And the berries make a really nice cider”.  I’ll have to try making some.

Mimulus lined the trail covered in bright orange blooms. Their common name is monkey flower and Val told us she is authorized to collect their seed for revegetation projects. She places the seed pods in a box and then walks over them. It’s my “monkey flower walk”, she laughed. Interesting to note that with the rise of genetics many plants have been reclassified and renamed. This drought tolerant plant is now diplacus. Seems with all these name changes many of us are using common names more and more.

We found a small stand of the endangered spineflower. ‘Not as many this year”, she told us. Some years they will carpet open areas with small dusty rose flowers. The bush poppies were in full bloom. I was surprised to hear that they weren’t as prevalent in the sandhills until after the fire. The succession of plant life and how it paves the way for the next generation of plants is always being studied. It’s wonderful to witness firsthand.

yerba_santaOur area has a rich history of native people who lived here before us. Val enjoys sharing her knowledge of the old ways to be passed on to the next generation. Yerba santa grows everywhere in the reserve. Covered now with lovely lavender flowers, Val told us its the leaves that have long been shredded and steeped into a tea. Naturally sweet it’s a vasodilator and traditionally used to help with respiratory problems like bronchitis, asthma and colds.

The wildflowers may not be as plentiful this year due to the drought but we were treated to many little gems. Peak rush rose, a rockrose relative, bloomed with tiny yellow flowers. Purple gila flowered near the endangered Ben Lomond wallflower. Western azalea were just finishing their bloom cycle in a moist swale going down to Reggiardo creek. Blue dicks, silver bush lupine, sky lupine and a California poppy of a distinct genera and sporting a deep yellow color lined the path.

At the Reggiardo creek we saw dozens of flowering plants surrounding the Reggiardo_waterfallfalls, including heuchera, ceanothus papillosus, saxifrage, redwood sorrel, redwood violets, deer fern and Western burning bush.

My day at the reserve was filled with beauty and new found knowledge thanks to Val Haley, her expertise and her wonder-filled spirit. If you would like a preview of what you may see when you go visit the website-
