Native Plant Communities in Sustainable Landscaping

/in , /by

Plants growing wild naturally arrange themselves into communities with other plant varieties based on their shared characteristics such as water and nutrient needs. This natural selection extends to interactions with each other, and with other species such as insects, birds, and other animals.

As a result, we see the same plant communities occurring repeatedly in natural landscapes under similar conditions.

Local native plant communities evolve together over a long period of time.  These plants work together to compete for nutrients, sunlight, and other resources.  They flourish together, to the point of “rejecting” non-native plant varieties attempting to establish themselves. While non-native plants may be equally adapted as native plants to the climate conditions of a particular area, they are at a disadvantage.

By learning about the San Diego region’s native plant communities, and selecting plants that like to live together in communities for sustainable landscaping, homeowners can take advantage of these strengths and the resulting hardiness.

Three examples of San Diego region plant communities

California Coastal Prairie Community

California’s coastal prairies are North America’s most diverse grasslands. Perennial flowers outnumber the native grass species. Plants include: California Poppy (Eschscholzia californica), Blue-eyed Grass (Sisyrinchium), Fern Leaf Yarrow (Achillea ‘Moonshine’), Seaside Daisy (Erigeron glaucus), and Cliff Buckwheat (Eriogonum parvifolium).

California Coastal Sage Scrub Community

Fire-adapted, drought-deciduous plants flourish in California coastal sage scrub.  This habitat is rapidly disappearing due to urbanization in southern California. Fortunately, some areas, including the San Diego Safari Park Biodiversity Reserve, have been conserved. Plants include Grey Musk Sage (Salvia Pozo Blue), Sticky Monkeyflower (Diplacus aurantiaus), San Diego Sage (Salvia munzia), Fuschia Gooseberry (Ribes speciosum), and Woolly Bluecurls (Trichostema lanatum).

California Chaparral Community

Chaparral exists in many coastal ranges and on the western and eastern slopes of the southern California mountains. It is ‘hard’ brush that doesn’t rely as much on summer fog drip that the Coastal Sage Scrub does, and it is adapted to heat and drought. Plants include Desert Mallow (Sphaeralcea ambigua), Bent Grass (Agorstis pailens), San Diego Mountain Mahogany (Cercocarpus minutiflorus), Bush Poppy (Dendromeconi riguda), and Clumping Wild Rye (Leymus condensatus).

California’s Drought Leads to Cutbacks in Marin County but Not in San Diego

/in , , /by /The Wall Street Journal by Jim Carlton Quoted: San Diego County Water Authority

At the southern end of California, residents have been assured their water supplies are secure and plentiful despite the state’s severe drought.

In Marin County, 500 miles north, lawn sprinklers are allowed only two days a week, washing a car at home is banned, and decorative fountains can’t be refilled. The orders are part of an effort by the local water district to cut usage by 40% after a precipitous fall in the local reservoirs.

The pain of a two-year drought drying up the American West isn’t being felt evenly across the country’s most populous state.

That is because Southern California water agencies have for decades invested in new ways to diversify their supplies and recycle what they get, say people who study and work with water in the West. In Northern California, meanwhile, a history of more plentiful rain and snow meant many communities were less prepared for the latest drought and now more homes and businesses must cut back.

As Drought Ravages California, Biden’s Infrastructure Bill Could Help Store More Water

/in , , /by /The Sacramento Beeby David Lightman and Dale Kasler

As California and the West suffer through an epic drought, President Joe Biden and Senate Republicans and Democrats have included $5 billion for Western water projects in their infrastructure deal.

The prospect of federal money comes as several big-ticket water projects are on the drawing boards in California — although many are still years from completion and probably wouldn’t get finished in time to help California with the current drought.

Ramona Water District Directors Discuss Water Rates, Rationing and Proposal for Meters on Wells at Forum

Ramona Municipal Water District Board Directors Jim Hickle and Jim Piva delved into water issues and touched on emergency services at a June 26 meeting sponsored by the American Liberty Forum of Ramona.

About 50 people who attended the forum at the Ramona Mainstage had the opportunity to ask questions on topics related to water rates and services, proposed indoor residential water rationing of 55 gallons per person per day, proposed water meters on wells, and the response to a call for a third ambulance in Ramona.

It’s Some of America’s Richest Farmland. But What Is It Without Water?

/in , , /by /The New York Timesby Somini Sengupta

In America’s fruit and nut basket, water is now the most precious crop of all.

It explains why, amid a historic drought parching much of the American West, a grower of premium sushi rice has concluded that it makes better business sense to sell the water he would have used to grow rice than to actually grow rice. Or why a melon farmer has left a third of his fields fallow. Or why a large landholder farther south is thinking of planting a solar array on his fields rather than the thirsty almonds that delivered steady profit for years.

Opinion: Proposed Budget Doesn’t Do Justice to Water Storage

/in , , /by /CalMattersby Vince Fong

Gov. Gavin Newsom and legislative Democrats had the opportunity to alleviate the state’s twin crises of drought and wildfire by including resources for ongoing funding, prescribed burning and water storage in this year’s budget. These solutions are not new, but they require political will. In light of the haunting memories of past catastrophic wildfires, this year’s budget will miss an opportunity.

Opinion: Record-Setting Heat Wave Shows That Climate Change is Creating Hell on Earth

/in , /by /Los Angeles Times by The Times Editorial Board

The record-breaking heat wave baking the West Coast is another painful sign that climate change is here, and we have to adapt.

The Pacific Northwest has been sizzling, with conditions forecasters have described as unprecedented and life-threatening. Portland, Ore., hit 113 degrees Monday, breaking the previous all-time high of 112 degrees, set Sunday. About 100 miles to the south, in Eugene, the U.S. track and field Olympic trials were halted Sunday afternoon, and spectators were asked to evacuate the stadium, due to the extreme heat.

California’s Drought and Wildfire Dangers Rising at Stunning Pace

/in , , /by /Los Angeles Timesby Faith Pinho and Alex Wigglesworth

California’s drought and wildfire conditions are accelerating at unprecedented rates, according to state officials, and residents should brace for a summer of widespread burning and mandatory water conservation measures in some regions.

As reservoir levels across the state continue to drop, and as parched vegetation poses an increasing threat of wildfire, officials in Sacramento and Southern California offered a bleak assessment of the state’s drying climate, saying it has already begun to affect people, plants and animals.

Drought Woes in Dry US West Raise July 4 Fireworks Fears

/in , , /by /AP Newsby Lindsay Whitehurst

Many Americans aching for normalcy as pandemic restrictions end are looking forward to traditional Fourth of July fireworks. But with a historic drought in the U.S. West and fears of another devastating wildfire season, officials are canceling displays, passing bans on setting off fireworks or begging for caution.

Fireworks already have caused a few small wildfires, including one started by a child in northern Utah and another in central California. Last year, a pyrotechnic device designed for a baby’s gender reveal celebration sparked a California blaze that killed a firefighter during a U.S. wildfire season that scorched the second-highest amount of land in nearly 40 years.

Some regions of the American West are experiencing their worst drought conditions in more than a century this year, said Jennifer Balch, director of Earth Lab at the University of Colorado.
