Five Firefighting Plants Worth Adding to Your Landscaping

As spring temperatures rise, San Diego County residents know wildfire season is not far behind. Although wildfire is a serious threat during warm, dry summer and fall months, wildfire can strike year-round especially in wildland interface areas. Regional landscaping must follow fire safe guidelines in design, plant selection and consistent maintenance.

Protecting your home with firefighting plants

Plan your landscaping using three different zones

Zone 1: Landscapes should resist ignition and provide 35 feet of actively maintained defensible space around structures and access areas through smart design elements and plant selection. This maximizes fire prevention and allows access by fire crews to protect your property from fire if necessary.

Zone 2: Careful thinning of native vegetation for at least 65 additional feet, for a total of 100 feet of defensible space will reduce the chance of airborne embers from catching and spreading fire.

Zone 3: Some plants begin growth and start the germination process after a wildfire. Many of San Diego County’s native plant communities including chaparral can survive and recover from infrequent wildfires.

But the ability to survive is disrupted for even the most well-adapted plants when fires reoccur too frequently. Non-native, invasive plant species encourage more frequent, longer duration fires burning at a hotter intensity. It is critical to remove invasive plants in fire-prone areas.

Choose firefighting plants that resist ignition

Some native plants can prevent airborne plant embers due to high salt or water content and low volatile oil content in their leaves. Succulents such as agaves, aloes and crassulas store extra water in their fleshy leaves guarding against drought, and they will help guard your property from wildfire.

Five exceptional firefighting plant choices include:

  • Daylily hybrids
  • Coral Aloe
  • Bush Morning Glory
  • California Sycamore trees
  • Indian Mallow

Rob wildfires of the fuel they need  

Messy, oily trees and shrubs like eucalyptus trees and junipers may flourish in Southern California, but they aren’t natives, and they provide ready fuel for wildfires. They ignite quickly, burning hot and long, releasing embers into the air which causes flames to spread.

Preventative maintenance includes removing dry grass, brush, weeds, litter, waste, and dead and dying vegetation. Trees should be regularly pruned. Shrubs should be thinned, with dead branches and leaves removed. Leave root structures intact to avoid erosion.

Dead leaves and branches are especially flammable on evergreen shrubs and vines like bougainvillea. Avoid planting these close to homes or other structures.

Gavin Newsom Declares a Drought Emergency – But It’s Limited to Two Counties in California

Gov. Gavin Newsom officially declared a drought emergency Wednesday in one of the driest regions of California, the Russian River watershed in Northern California.

While the governor stopped short of declaring a statewide drought, the move makes various forms of drought assistance available for Sonoma and Mendocino counties and could allow the state to take swifter action on curtailing farmers and others from pulling water from the river.

However, Newsom said his order won’t bring the imposition of water-conservation mandates.

Drought Spreads Water Shortages Throughout State

The 2020-21 California drought has led to significant water cutbacks, compelling farmers to fallow ground and public officials to respond with legislation intended to address the state’s chronic water shortages. Farmers in more parts of the state have learned in recent days just how little water they will have available to them this summer, as water suppliers from the Oregon border to the North Coast to the San Joaquin Valley announced low allocations.

This Stunning Timelapse Shows the Megadrought’s Toll on the West’s Largest Reservoir

Just how bad is the drought in the Western US? The shrinking of Lake Mead, the country’s largest reservoir, is a troubling indicator.

The massive man-made lake, which straddles the border of Arizona and Nevada, is now only at 39% of its full capacity, down from 44% in April 2020. That’s equivalent to a 10-foot drop in the water level, according to the latest data from the Bureau of Reclamation. Which means mandatory restrictions on the amount of water surrounding states draw from Lake Mead could be triggered in the next few months.

Opinion: Recycling Water has to Become the Norm Because it is Too Scarce and Too Valuable to Waste

Like millions of teens around the world, my daughter enjoys long showers. Unlike many fathers of teens, however, I see a bright side to the family water bill. We’re not just taking showers. We’re growing grapes.

Our family lives in Israel, the international capital of water recycling, where nearly 90% of our supply is used more than once. In our area of southern Israel, that means the water flowing down our home drain is used on nearby farms to grow some of the tastiest table grapes on Earth. Turns out my daughter is a friend of agriculture.

All over the globe, climate change is turning fresh water into an increasingly precious commodity. Many countries and regions suffer from extended drought. Rising temperatures increase evaporation from reservoirs. Snow falls less and melts sooner on mountains. And rising sea levels increase saltwater intrusion contamination in fresh water wells along coastal communities.

“We’ve Been Here Before”: Valley Counties Pile on Newsom to Declare Drought Emergency

A coalition of Central Valley counties is urging Gov. Gavin Newsom to declare an emergency declaration in response to the drought crisis.

The chairs of the Board of Supervisors for Fresno, Madera, Stanislaus, Tulare, San Joaquin, Kings, Kern and Merced counties sent a joint letter to the governor in support of a letter from a bipartisan mix of Valley legislators spurring a yet-to-be-issued emergency declaration.

Santa Maria Providing Customers with Groundwater Due to Drought

The City of Santa Maria is providing all of its customers with groundwater supplies, due to the drought. The City says it’s meeting all drinking water standards, but customers may notice a difference in the water due to the increased hardness and mineral content. The exclusive use of local groundwater will continue through May, and the City anticipates again relying solely on the groundwater basin for November and December.

An Earth Day Message for California: Move Faster on Climate Change

If there’s one thing to understand this Earth Day about California’s role in confronting the climate crisis, it’s this: Just because the state considers itself a global leader doesn’t mean it’s doing nearly enough.

Marin to be First Big Bay Area Water Agency to Push Ahead with Water Restrictions

As drought conditions worsen across Northern California, the Marin Municipal Water District is about to become the Bay Area’s first major water agency to make the leap to mandatory water restrictions.

The utility is expected to adopt a plan Tuesday that would require nearly 200,000 residents of southern and central Marin County to limit outdoor watering to one day a week as well as to stop washing their cars, refilling their swimming pools and power-washing their homes, among other things. Offenders could face fines of up to $250.

Water Levels Low at Folsom Lake as California Faces Threat of Drought

Sunday marked the hottest day of the year, so far. Many people made their way to Folsom Lake to enjoy the weather to find lake levels low as the state faces the threat of a drought. After two dry years in a row with little rain and snow, drought is a concern. Last week, Gov. Gavin Newsom said he has executive orders drafted, if needed.
