Life as a Seed: Harvest, Plant, Grow, Repeat

2/27/2015

 
Picture
Seeds used in habitat restoration on much of the Irvine Ranch Natural Landmarks are set up for success by using a “go local” approach.

Landscape-scale habitat restoration over hundreds of acres starts small-scale, with the seed. One seed planted will hopefully become a mature plant producing many more seeds, in turn becoming many more healthy plants. Active habitat restoration is all about making that first seed as successful as possible, and Irvine Ranch Conservancy scientists have developed a strategy to give as many successful seeds as possible back to the land. Their success weighs in at more than 600 pounds of farmed seed each year.

Tiny Pest Means Big Trouble for Oak Trees

2/20/2015

 
Picture
An invasive beetle found in local oak trees was likely brought to Orange County in firewood.

The tiny Goldspotted Oak Borer has killed tens of thousands of mature oak trees in San Diego County since it was first identified there in 2004. Recently, this destructive pest was found in the Weir Canyon area of the Irvine Ranch Natural Landmarks, and local agencies are working quickly to isolate the infestation and prevent a similar tragedy here in Orange County.

The beetle infestation was found in 56 mature oak trees in a remote area of Weir Canyon. Of those infested, 20 were cut down and removed due to heavy infestation. OC Parks is working with Irvine Ranch Conservancy to treat and preserve the health of the rest of the affected coast live oak trees. Both groups are also working with OCFA, University of California Cooperative Extension, and state and federal fire agencies to develop a response plan in case the Goldspotted Oak Borer is found again in Orange County.

Big Changes in Big Canyon

2/6/2015

 
Picture
Ongoing habitat restoration efforts in the Big Canyon area near Upper Newport Bay have brought many improvements, and there are big plans there for the future.

Since August of 2013, big things have been going on in Big Canyon, one of several large tributaries of the Upper Newport Bay. The City of Newport Beach initiated a habitat restoration project led by Irvine Ranch Conservancy, which has so far resulted in enhanced aesthetics of the canyon, a healthier balance of native flora and fauna, and an improved experience for those who visit.

The project has been a true community effort, with about 15 volunteer programs held in the past two years. The nature reserve area also benefits from nearby restoration projects led by the Newport Bay Conservancy and the Coastal Commission’s ROOTS program, supporting the overall health of greater Newport Bay.
