LGB Speaks About Corridors at SCAG

Last week, Harry Huggins, a Director at Laguna Greenbelt, Inc., spoke to the Southern California Association of Governments (SCAG), a regional association that helps the six counties in southern California coordinate planning efforts in transportation, sustainable development, and other issues. As SCAG works on the next iteration of the Regional Transportation Plan (RTP) and Sustainable Communities Strategy (SCS) – documents that will guide our region’s future development – community members’ comments can help the agency better understand the needs of our region. More information about SCAG’s process for updating the RTP/SCS can be found here. Thanks, Harry, for voicing the need to incorporate wildlife corridors into our urban landscapes! An excerpt of his speech is below:

“Wildlife corridor awareness is blossoming at many levels of government in California, from the recent passage of SB498 to efforts at CalTrans to incorporate connectivity into new projects.  I know that SCAG has already supported efforts in Los Angeles County at Liberty Canyon to create a wildlife corridor over the 101 Freeway. Kudos for your fine work, but know that this is just one of many efforts underway across the region to connect natural lands to one another.  Wildlife Corridors are very important to the region and its biodiversity because they allow species to migrate, forage and expand genetic diversity. Personally, I think this is what we all want for our families.

Right now, my organization is part of a coalition that is re-establishing an important connection between two protected open spaces: the Laguna Coast and the Santa Ana Mountains.  Wildlife populations suffer dramatically when they do not have enough room to roam, cannot find suitable mates, don’t have appropriate nurseries for their young, or aren’t able to repopulate nearby natural lands after an ecological disaster (like a fire or flood in their own territory).  Completing this Coast to Cleveland Connection—a wildlife corridor— will correct a planning error.  It may also help the region to better cope with changes caused by climate change, a concern that the State of California is addressing on many fronts. 

The 2016 RTP/SCS would be stronger if it supported the enhancement of and/or protection of documented and regionally significant wildlife corridors, especially those that are impacted by infrastructure projects.  Our wildlife know no geographical-political boundaries, so let’s work together to connect our landscapes.”

Community-Supported Agoura Hills Wildlife Crossing Benefits the Region; Questions Arise For Recreational Use of Bridge

By Gabriela Worrel

On January 14, Laguna Greenbelt, Inc. attended the first public scoping meeting presenting the Liberty Canyon Wildlife Crossing in Los Angeles County. It was an inspirational event, and it became clear by the end that there was a lot of love in the room for wildlife and open space from local residents, political leaders, and community organizations.  About 300 people joined Caltrans at the King Gillette Ranch on January 14, 2016 to hear the agency’s proposal for a green bridge over Highway 101 in Agoura Hills at Liberty Canyon Rd. The agency presented three options: one involving no action, one involving a bridge over the freeway only, and one involving a bridge extending over the freeway and Agoura Rd. The bridge would be a vital linkage between two important large ecosystems in the Santa Monica Mountains and the Santa Susana Mountains. The project is expected to cost $55 million. The National Wildlife Federation has committed to raising the necessary funds through private donations and public funds already slated for conservation projects like this one. The crowd seemed to overwhelmingly support the project, and not one person voiced opposition to the project during the public comment period – a rare occurrence indeed.

Both bridge options include the presence of a recreational trail on the bridge – one that would connect hiking trails on either side of the freeway and undoubtedly delight local outdoorsman, for good reason; What nature-loving trekker wouldn’t want to be able to cross over the 101 in search of more nature? This being said, Laguna Greenbelt supports the building of this project, and strongly urges Caltrans to carefully consider the impact of humans and domestic animals such as dogs and horses on the movement of wildlife across the bridge. Some studies done in our region have shown that even intermittent presence of humans and animals can discourage the presence of key predator species (*note references in footnote?). This may potentially undermine the success of animals using the bridge – we will ask Caltrans in our comments to bring in experts (to comment) on this issue during the next phase of the project.

The impetus for the overpass has been a desire to prevent animal mortality on local highways and genetic inbreeding in mountain lions living in the region. Caltrans reports that: “The purpose of the proposed project is to provide a safe and sustainable wildlife passage across the freeway in order to help create an important linkage in the region. The crossing would help reduce wildlife mortality, ease animal movement across habitats, and allow for the exchange of genetic material.” The location was selected for a variety of reasons, including the presence of protected open space on both sides that is not at risk for development, and past attempts by animals to cross the freeway at this point.

Studies conducted by public agencies over the past two decades have shown that mountain lions, which live solitary lives and typically need large ranges to roam and find new mates, are blocked from movement by highway 101. As a result, they are particularly at risk for problems resulting from competition for space among young cougars, and genetic inbreeding. Seth Riley, a head biologist for the National Park Service and consultant on the project, noted that already, genetic analyses have shown decreases in genetic variability in the population adjacent to the freeway. While the main target is mountain lions, the bridge will also benefit other species, such as the Western Fence Lizard, skinks, and a bird called the wrentit, among others.

The next step for the project is for Caltrans to gather public comments and produce an Environmental Document. Public comments may be submitted through January 29, 2016 at liberty.canyon@dot.ca.gov, or mail a letter to Barbara Marquez, Senior Planner (click on Caltrans link below for the address). The agency expects to show the project will have no negative environmental impacts, thus avoiding the need to complete an Environmental Impact Report.

Laguna Greenbelt, Inc. is currently working to see the completion of the Coast to Cleveland Wildlife Corridor in Irvine, California, and while the Liberty Canyon Crossing is in the neighboring county, wildlife connectivity is a regional issue – not just a local one – especially when we know that many animals have large ranges and need to move between distant ecosystems to thrive. This crossing would be an exciting development for wildlife in southern California in order to maintain the genetic diversity in the Orange County coastal wild lands, the Santa Ana Mountains, and beyond.
