More than century ago in the desert Southwest, a small, grayish-green songbird — the southwestern willow flycatcher (Empidonax traillii extimus) — spent the hottest part ofthe year flitting about in dense streamside thickets, building its nests and rearing its offspring before migrating back to Latin America at summer’s end.
Over time, suitable nesting habitat along waterways shrank as a result of changes in land use and water management, and with it the flycatcher’s populations shrank, too.
The Mission San Gabriel was founded, in what is today San Gabriel, CA, by Franciscan priests at the end of the 18th century as part of Spanish colonization of Alta California. The Mission is very important in the history of California and to native peoples as well.
Before pipelines can be constructed and come online, they often require a host of permitting services and environmental studies.
SWCA was hired to provide input on routing and pre-construction delineations of wetlands and waters of the U.S., cultural resource surveys, and threatened and endangered species assessments for a natural gas liquids pipeline stretching 720 miles to connect wells in the Permian Basin and Eagle Ford Shale formation to fractionation plants along the Texas Gulf Coast.
