Bird Blog
and Photo Links June 26, 2010. I
visited Sepulveda Basin Wildlife Reserve today in the morning between 8:30
AM and 11:30 AM. The morning was very cloudy. At 10:35 AM, a Barn Owl
appeared right in front of me out of nowhere. It was the first time that I
observed a Barn Owl flying at this time of a day at Sepulveda
Bull Creek Restoration Project In spring of 2009 the Bull Creek Channel Ecosystem restoration project was completed. Features were to include 28-acres of aquatic, riparian and native upland habitat to enhance wildlife resources along the Bull Creek channel. An oxbow (or “C”-shaped) side channel was excavated to allow water to flow from south of Victory Blvd. around an island to the Los Angeles River, but the storms of the winter of 2009-2010 resulted in severe erosion along the creek banks and the complete filling in of the oxbow with silt. The construction portion of the project was completed in May, 2009. Reclaimed water from Lake Balboa is flowing into the channel near the oxbow to enhance the existing flow. Below is a sequence of images showing the finished project, the first erosion on the east bank, the filled in oxbow, and the ensuing emerging vegetation.
Native plantings include thousands of willows, cottonwoods, box elder in the riparian areas and acres of hydroseed on the hillsides. Weeds have been a problem with this project from the beginning, and now that the one year contractor's maintenance requirement is over (as of about April 1), the weeding responsibility falls to the City (suffering from tight budgets) and volunteers. If you would like to help weeding, please contact volunteer@sepulvedabasinwildlife.org. A couple of small hills were created as part of this project and they are covered with mostly native wildflowers, including yellow yarrow, sticky monkeyflower, Plantago, mints (Salvia spp.), California poppies, and others. Mixed in with these plants are various native shrubs including California walnut. At the base of the hill and on the surrounding areas is a (so far) very successful planting of native bunchgrasses.

Corporation Formed to Help Transform LA River
A nonprofit
corporation was established Tuesday to help
advance a decades-long plan to transform 32
miles of the concrete-filled Los Angeles
River into a strip of parks, walkways, bike
trails and housing. The Los Angeles River
Revitalization Corporation is tasked with
buying, selling and developing property
along a portion of the river stretching from
the west San Fernando Valley to East Los
Angeles. To read more, click

About this Website |
SBWASC Mission Statement |
|||
This website is sponsored by the Sepulveda Basin Wildlife Areas Steering Committee (SBWASC) that has been meeting monthly since June 1990. The purpose of the Committee is to advise the City of Los Angeles Department of Recreation and Parks concerning the operation, maintenance, and improvement of the existing wildlife areas and any future expansion thereof. The Committee may also make recommendations on matters concerning flora, fauna, and other natural resources in other areas within the Sepulveda Basin, such as the Los Angeles River and its tributaries, park land, and open spaces. RULES AND REGULATIONS The
“Public Recreational Use Plan Sepulveda
Basin Wildlife Area” was signed and agreed to in 1987 by the City of
Los Angeles, the U.S. Army Corps of Engineers, and the State of
California Department of Fish and Game (copy attached). The “Public
Access and Use” section (beginning on Page 6) provides, in part, as
follows: |
. The mission of the Committee shall be to oversee, in its advisory capacity, the wildlife refuge areas and other areas of present or potential natural value within the Sepulveda Basin, as well as to support policies and programs that ensure their long-term preservation, protection, and enhancement.
Article 3, Section 63.44 of the Los Angeles Municipal Code contains Regulations Affecting Park and Recreation Areas. 63.44 B-2 mandates that all dogs be on a leash less than 6 feet long, B-10 prohibits bows or crossbows, B-11 prohibits the take/seizure/hunting of all birds/animals/fish, B-12 bans the removal of wood/plants/rocks/soil, B-13 makes it illegal to deface any property (including plants), B-14 prohibits all loitering between 10:30 PM and 5:00 AM, B-16 prohibits all human or motor powered vehicles (except on trails or roads specifically for that purpose), B-17 bans all fires, B-19 prohibits littering, B-21 bans firearms.

About the Sepulveda Flood Control Basin |
||||
All property within the Sepulveda Flood Control Basin is owned by the Los Angeles District Corps of Engineers, but more than 80% of the land is leased out for recreational and agricultural uses. Sepulveda Dam, completed in 1941, is a dry-land reservoir, with the purpose of controlling runoff from nearby San Gabriel, Santa Monica, and Santa Susana Mountains.
Besides the Encino and Balboa golf courses, the Balboa Sports Complex, and the model airplane field, most of the Basin was devoted to agriculture (corn and then sod farms). In the mid-1960’s, Burbank Blvd. was extended across the Basin. In the 1970’s the City of Los Angeles Bureau of Sanitation built the Donald Tillman Water Reclamation Plant within the Basin (over the objections of the Corp of Engineers). |
||||
In March of 1981, a revised Master Plan for the area was adopted. At the time, of the 2,150 acres in the Sepulveda Basin, approximately 1,060 acres were committed to recreational uses. The updated Master Plan designated an additional 540 acres for future recreational uses. Included in the plan are provisions for the commitment of approximately 220 acres of land to informal park space, 120 acres for development of a recreational lake, 108 acres for a wildlife management area, and 60 acres for an “arts park” that has been subsequently redesignated for a “sports complex” (the area west of Balboa Blvd. just north of the Los Angeles River. |
||
The Master Plan also tried to minimize adverse environmental effects and recommended “designing reaches of newly-formed lakes and ponds |
||
In 1979 the Corp of Engineers developed the first area of the Wildlife Reserve (now called the South Reserve), an approximate 48 acre parcel located south of Burbank Blvd and bordered by the Los Angeles River and the Sepulveda Dam on the east and south. A “pothole” pond (fed with piped-in fresh water) was created, and vegetation representing coastal sage scrub and riparian woodlands were planted. |
||
The approximate 60-acre North Reserve (north of Burbank Blvd., east of Haskell Creek, west of the Dam) was developed in 1988, featuring an 11-acre lake with an island and wildlife viewing stations. Various revegetation projects have been undertaken since then. |

the reserve entrance and restrooms. |
||||
In 1991 the Tillman Water Reclamation Plant Flood Protection Project was finalized, and subsequently a berm was built around the Water Reclamation Plant to protect it from flooding, compensating excavation was performed in various places, and the outflow from the Water Reclamation Plant was rerouted under the dam so the outflow was outside (to the south) of the Dam. The 7-acre berm was planted with California native plants and is the largest native landscaping project developed by the City of Los Angeles. |

In 1994, the City and Federal governments agreed to sharing the costs on $11 million in improvements in the Sepulveda Basin. The wildlife are was expanded 110 acres to the west of Haskell Creek (on either side of Woodley Avenue). Additional facilities in the wildlife area included trails, restrooms and staging area, signs, benches, viewing blinds and parking. This project was completed in 1999. |
