New Restoration Project Will Help Maintain Oak Woodlands in Limestone Canyon

2/6/2020

 
PictureOaks in Limestone Canyon
Since 2005, Irvine Ranch Conservancy has made it their mission to preserve and restore natural habitats found throughout the Irvine Ranch Natural Landmarks. With their newest restoration project, Irvine Ranch Conservancy staff and volunteers will plant 500 acorn seedlings at the Augustine Staging Area Nursery in Limestone Canyon that will be used to maintain vital oak woodland habitats.
 
The acorns collected by the Conservancy are sourced locally from oak trees throughout the area, giving them a greater chance of success due to acclimation to local climate and soil. After the acorns are collected, they will then be planted at the Augustine Nursery, where staff and volunteers will assist in tending and growing the acorns to seedlings until they are ready for planting. Restoration projects such as this allow Irvine Ranch Conservancy to expand its work of restoring habitats that support local wildlife and plant species.

Celebrate Groundhog Day with Restoration Activities on the Landmarks

1/30/2020

 
PictureYoung volunteers helping at the Native Seed Farm
​As February 2nd approaches, people across the U.S. await the season’s forecast from Punxsutawney Phil to see if we will experience six more weeks of winter or an early spring. Starting in the 1880s, Groundhog Day has become an annual winter tradition complete with a full ceremony in Punxsutawney, Pennsylvania.
 
While those living in colder climates might pay more attention to the tradition, residents of Orange County don’t have to worry too much about Phil’s prediction. The brisk cool temperatures and sunny skies make for easy winters in Orange County and an ideal time to help restore and protect native habitats. The wet winter months across the Irvine Ranch Natural Landmarks can bring much needed rainfall that leads to lush greenery throughout the open spaces.

Landmarks Focus: Goats!

7/12/2019

 
PictureGoats in Bommer Canyon
If you happened to be passing by Bommer Meadow in the month of May, you might have noticed something unexpected – a herd of goats! The goats were assisting with the beginning stages of a multi-year restoration project being conducted by the Irvine Ranch Conservancy in partnership with the City of Irvine in Bommer Meadow, which was historically part of a working cattle camp. Livestock grazing and the introduction of non-native plants and weeds degraded the natural habitat over time, reducing available food, water and shelter for native plants and wildlife. Invasive plants do not provide the resources necessary to support healthy native wildlife populations, and they also increase wildfire risk, so it is crucial to restore degraded areas with native vegetation to provide wildlife with a functioning habitat and to reduce wildfire.

Irvine Ranch Conservancy Experiment with Goats to Help Restore Natural Habitat in Bommer Canyon

5/16/2019

 
​The Irvine Ranch Natural Landmarks are home to a variety of natural habitats and native plant species. These habitats can be disrupted by invasive plants and weeds that are harmful to the native flora of the lands. Restoring native habitat is an important goal of the Irvine Ranch Conservancy, but before native plants can be re-introduced to a specific area, non-native plants must be removed.
 
Irvine Ranch Conservancy has partnered with the City of Irvine to implement a multi-year habitat restoration project in Bommer Canyon. The process will begin with a little help from nature’s mowers – goats! Unlike other habitat restoration methods, this experimental activity utilizes a controlled method of livestock grazing to remove non-native plants, weeds, and thatch that have degraded the natural habitat over time. Goats can access certain areas mowers can’t such as steep slopes or rocky areas and are being used as an experiment to see how effective they can be in other situations. With their seemingly endless appetites, goats graze down to the soil, which will allow Irvine Ranch Conservancy staff to plant native seeds and plants at the cleared site and restore the area to its native habitat. The end goal of the project is to return Bommer Canyon to a healthy, lush mix of native grasslands and coastal sage scrub – a rare habitat found only in Southern California.

Landmarks Focus: Oak Restoration in Weir Canyon

4/4/2019

 
PicturePlanting Oak trees in Weir Canyon
OC Parks Weir Canyon Nature Preserve contains an abundance of rare habitats and wildlife, including one of the largest intact coast live oak woodlands in Orange County, making it one of the most ecologically important areas on the Irvine Ranch Natural Landmarks.  This area is admired year-round by hikers, bikers, and nature enthusiasts alike.  But this sanctuary is also under threat. 
​
The Gold Spotted Oak Borer Beetle, or GSOB for short, is an invasive tree pest that has been documented within Weir Canyon.  Native to southeastern Arizona, it is thought that the beetle first traveled to southern California through infested firewood.  This tiny beetle disrupts and depletes the ability of trees to take up nutrients by laying its eggs on the bark of the trees. The larvae then burrow beneath the bark to feed, and eventually kill the tree.

​Irvine Ranch Conservancy’s Native Seed Farm helps wildflowers bloom across the Landmarks
 
Spring hasn’t sprung just yet, but signs of the coming season are already appearing across the Irvine Ranch Natural Landmarks. With the abundance of rain this year and Southern California sunshine, wildflowers are already beginning to bloom, bringing pops of color to Orange County. Irvine Ranch Conservancy staff and volunteers do their part in helping wildflowers flourish through restorative efforts on the Irvine Ranch Conservancy Native Seed Farm.
 
The Native Seed Farm has two goals: give the local community a way to connect with the land and provide a reliable source of quality plant material for restoration projects. The 14-acre farm is a sustainable way for the Conservancy to help restore thousands of acres of native habitat throughout the Irvine Ranch Natural Landmarks. Certified staff and volunteers are key to the operation of the Native Seed Farm, helping to grow and tend to a custom mix of native plants like wildflowers, then harvesting the seed for use on the Landmarks.

Oak Monitoring Program on the Irvine Ranch Natural Landmarks

1/10/2019

Oaks are an important part of the California ecosystem and are considered to be one of the state’s major types of vegetation. To most people, it might just be another tree, but oaks are considered to be a foundation species, in the sense that their presence defines and supports an entire ecological community. Oak woodlands are their own important habitat, providing crucial shelter, foraging opportunities, and watershed protection, along with enhancing the aesthetic value of the California landscape. Whether we know it or not, oak woodlands are right in our backyard. Oak woodlands in Orange County consist almost entirely of Coast Live Oak, an evergreen tree that extends up and down the California coast.
​
Over the years, these woodlands have been considered at-risk due largely to habitat conversion by humans, which has reduced the trees to 50% of their historical range or less. Other factors in the decline of oak woodlands in California are competition with non-native species, cattle grazing, drought, and new pathogens. One example of a new pathogen that has affected Coast Live Oaks in Orange County is the Goldspotted Oak Borer. This particular pest is native to Arizona and was first identified in California in 2004, but was not linked to extensive oak mortality until 2008.

Looking Back at 2018

1/3/2019

 
PictureAn oak seedling in Bee Flat Canyon
Restoration efforts on the Landmarks to create highly functional and resilient ecosystems
 
Nearly 40,000 acres of land preserved on the historic Irvine Ranch have been designated as a Natural Landmark.  This land contains important natural habitats, sensitive species, such as the California Gnatcatcher and Coastal Cactus Wren, and unusual geological formations. It is home to countless plants and animals as well as rocks and fossils, chronicling back nearly 80 million years.
​
However, many natural areas in our modern world need management to keep them wild and beautiful. In southern California in particular, threats such as increased fire frequency, invasive species, overuse, and a large surrounding urban population have all impacted our Natural Landmarks. As a result, over 18,000 acres of land are considered highly degraded and in need of restoration.

A year after the Canyon Fire and Canyon Fire 2, restorative and preventative efforts move forward on the open spaces
 
The fall season is in full swing and with it comes a change in weather and winds. October marks the one-year anniversaries of the Canyon Fire and Canyon Fire 2, and Irvine Ranch Conservancy staff, partners, and the Orange County Fire Watch Program are working with OC Parks to continuously implement programming to help restore and protect the Irvine Ranch Natural Landmarks. Nearly 40,000 acres of open spaces are home to wildlife and various rare and native species, and the work of staff and volunteers is incredibly important during the Santa Ana wind season and year-round.
​
The 2017 canyon fires affected Weir Canyon, Blind Canyon, parts of Fremont Canyon Nature Preserve and beyond, with assessment restoration efforts starting almost immediately after the fires were contained. All habitat types including coastal sage scrub, chaparral, grassland, oak woodlands, and riparian were affected by the fires, and most areas are showing signs of improvement and are expected to recover.

Restoration Success: Agua Chinon Continues to Thrive

10/6/2017

 
PictureWater from Agua Chinon joins the San Diego Creek, and ends in Upper Newport Bay.
Restoring degraded landscapes is a challenge, but the results can have a significant positive impact on native plants and wildlife. 

Five years ago, the 1,200-acre Agua Chinon canyon was filled with non-native species like pampas grass, castor bean and mustard weed, which invaded after numerous fires and years of cattle grazing. In 2013, the Irvine Ranch Conservancy with support from OC Waste & Recycling and OC Transportation Authority (OCTA) developed the Agua Chinon Restoration Project–an effort to revitalize the land in the Limestone Canyon Nature Preserve. The goals remain to remove invasive species, plant native species, and bring OC Parks’ Agua Chinon back to a thriving ecosystem for wildlife and a true destination for hikers. Now after five years of restoration work, Agua Chinon boasts enhanced habitat including oak and willow trees, elderberry, mule fat, and other native riparian plant life and associated wildlife.

Picture
Volunteers help restore riparian habitat in Agua Chinon.
“My life’s work is to be a part of a project that will have a lasting impact and undo some of the damage that’s been done to these lands,” said Robert Freese, the Restoration Project Manager. “It’s great to see the community get involved—from bird watching to stewardships—it’s really a community effort. You’re always learning something new in this constantly evolving process.”
 
The restoration project started with researchers gathering baseline data followed by two years of site preparation. During the process, “trial plots” were planted with various native species to identify which plants would thrive in the sandy soil. After two years, native species began to thrive. Visitors can now visit Agua Chinon and experience native plant life like shrubs, poppies and lupines.
Local wildlife has also returned to the native habitat, including the California Gnatcatcher, which can be spotted in spring and is dependent on the shrub habitat restored in Agua Chinon. Six times a year, crews venture to remote areas of Agua Chinon to complete bird surveys and monitor the insects and other wildlife. These surveys depict how the ecosystem is adapting to the restoration.
 
Today, site maintenance and monitoring continues in Agua Chinon. By working with the community through stewardship programs, invasive species are weeded out and native plants are re-introduced. Visitors can participate in stewardship programs to promote the restoration and see the benefits of their hard work first-hand through hikes and activities.

From Blight to Beauty

7/5/2017

 
PictureNative poppies and chia now bloom in Buck Gully where ice plant once dominated the hillside.
See the difference native plants can make at Newport Beach’s Buck Gully Reserve.

The Buck Gully Reserve within the City of Newport Beach encompasses 300 acres of high quality coastal sage scrub and riparian habitat bounded by single-family residences on one side, and the Pelican Hill Golf Course on the other. Still, the expanse supports a highly diverse native plant population and is the perfect respite for the region’s wildlife.
 
But amidst the native willows and sycamores, Buck Gully’s northwestern zone has been the site of degraded habitat.  The need to create “fuel breaks” or a Hazard Reductions Zone between the nearby homes and the wildlands had left the region with a hillside covered with invasive ice plant. And by 2013, the plant meant to suppress wildfires had mostly died, becoming a potential fire hazard itself.

Near Record-Rainfall Leads to Increased Habitat Restoration on the Irvine Ranch Natural Landmarks

5/4/2017

 
PictureA restored hillside in OC Parks' Limestone Canyon Nature Preserve shows the contrast between native plants (left) and invasive species such as black mustard (right).
After 5 years of extreme drought, Irvine Ranch Conservancy adapts to the recent rainy season through restoration of the open spaces.

The Irvine Ranch Natural Landmarks are home to thousands of acres of thriving native shrubland, woodland, and riparian communities, functioning as important habitat for the region’s wildlife and as natural landscapes for visitors to experience and enjoy.
 
Among the healthy environment lies degraded areas altered by years of cattle ranching and successive wildfires, and stressed by invasive plants and animals. Irvine Ranch Conservancy uses innovative techniques including native plant propagation and seeding, natural regeneration approaches, and targeted weed control on a large—or “landscape-scale”—to increase the area of healthy native habitat. The resulting biologically rich habitat is more resilient to wildfires, invasive species, and climate change. Over the past five years, extreme drought conditions created challenges at some sites. Native seeds struggled to germinate while nonnative drought-tolerate plants excelled, such as the Russian thistle, commonly known as the tumbleweed plant.

​

National Arbor Day is April 28, and there’s no better way to celebrate than by registering for a free program on the Irvine Ranch Natural Landmarks. With over 40,000 acres of protected open spaces, the Landmarks are home to many majestic species that are a vital part of Southern California’s Mediterranean climate. Some species provide shade while others rely on the warm climate to survive, and they’re all an important part of the local habitat. From the City of Newport Beach’s Buck Gully to OC Parks’ Limestone Canyon, there are a variety of trees to admire on the lands in honor of Arbor Day. 
​
​Coast live oaks (Quercus agrifolia) are among the most recognizable trees on the Landmarks, thanks to their distinctive, contorted branches that can stretch low and spread out in all directions. Mature coast live oaks can reach a height of up to 80 feet and can live for roughly 250 years if left to grow. Hikers can admire coast live oaks during the Thursday Morning Trek: Agua Chinon and The Sinks on Thursday, April 27, which begins in the City of Irvine and stretches into OC Parks’ Limestone Canyon Nature Preserve. Paved Hicks Haul Road in Limestone Canyon also offers coast live oak sightings during weekly programs.
