See the Oaks Calabasas Fire Part 2

Sometimes fire creates opportunity.
The oaks in the Calabasas fire may be toasted, but not taken down.
 HD 
 Firefighters saved the park structures.
And the non native grasses and shrubs burned.
 But there is hope for new growth!

Santana Winds Come to Los Angeles October 29, 2015

The Santana Winds have come to Los Angeles.
 October 29, 2015

The term "Santana winds" is said to have originated in Spanish California when the hot, dry winds were called "devil winds."


Maybe you've heard of them as "SANTA ANA WINDS"? 

At the turn of the last century, an Associated Press correspondent mistakenly identified Santana winds as "Santa Ana" winds in a 1901 dispatch.


Raymond Chandler wrote a 1938 short story about them called 
 "Red Wind"
"There was a desert wind blowing that night. It was one of those hot dry Santa Anas that come down through the mountain passes and curl your hair and make your nerves jump and your skin itch. On nights like that every booze party ends in a fight. Meek little wives feel the edge of the carving knife and study their husbands' necks.
Anything can happen. You can even get a full glass of beer at a cocktail lounge."

Leaves on CA Native Plants Fight Drought

San Nicolas Island buckwheat
Despite the drought, you can still have green landscaping in California if you go native. Take a minute and appreciate the variety of leaves among our native plants.

These natives are green and healthy even at the end of a dry summer.

How do they do it?  Adaptations to their leaves help them avoid moisture loss. 

Some leaves are fuzzy with tiny filaments that help break of the sun's pounding rays. A velvety leaf also reduces air movement across the surface, thereby reducing transpiration of moisture.

Waxy leaves help seal in moisture, also reducing transpiration. 

San Nicolas Island chamise
Narrow leaves reduce surface area exposed to the sun. Some plants like the fairy duster (Calliandra) respond to direct sunlight by closing up their leaves to further reduce exposure. When the sun is less severe, the narrow leaves unfurl and open wide.

Many California native plants have evolved with combinations of these adaptations making them successful drought survivors and good choices for planting in yards.

Here is a list of the plants as they appear in the video:
  • hollyleaf cherry (Prunus ilicifolia ilicifolia) more on CA native cherry
  • ceanothus (Ceanothus variety of species) flowers in the spring
  • white sage (Salvia apiana)
  • San Nicolas Island buckwheat (Eriogonum grande timorum)
  • manzanita (Arctostaphylos variety of species)
  • hollyleaf cherry (Prunus ilicifolia ilicifolia
  • coast live oak (Quercus agrifolia)
  • toyon (Heteromeles arbutifolia) more on toyon
  • lemonadeberry (Rhus integrifolia)
  • penstemon (Penstemon variety of species)
  • prickly pear cactus (Opuntia ficus-indica)
  • San Nicolas Island chamise (Adenostoma fasciculaton 'Nicolas') See more of San Nicolas Island
  • pink fairduster (Calliandra eriophylla)
  • sword fern (Polystichium munitum)
  • CA coast redwood (Sequoia sempervirens)
  • giant sequoia (Sequoiadendron giganteum)
  • Santa Rosa Island torrey pine (Pinus torreyana insularis)
  • western sycamore (Platanus racemosa)
  • mallow (Sphaeralcea variety of species)
