Among the small natural features that can have disproportionate ecological value are the bark of grand old trees, which has nooks and crannies that provide microhabitats for wildlife; patches of native plants alongside agricultural fields, which can provide some species with their only remaining natural habitat; and rocky outcrops, which nurture unique and diverse flora and fauna. Other benefits of conserving these modest yet influential—and often under-appreciated—landscape features include relative ease and affordability as well as compatibility with land uses such as grazing and forestry. Even seemingly minor features, the researchers say, can have “roles that may be critical in the function of their broader ecosystems and the fate of biodiversity.” RM

Small-scale conservation can have outsized ecological impacts, says an international group of researchers.

Asked to suggest an appropriate future for four Delta islands owned by the Metropolitan Water District, it’s difficult not to want the moon.

Why not richer rice fields, more wetlands, better boat launches, extended trails, even eco-tourism? ? A new survey for the Delta Islands Adaptation Project, funded by a Prop 1 Watershed Restoration Grant, wants the public’s opinion on the importance of 10 possible land-use objectives leading to the selection of one...

An examination of 50 years of records reveals an apparent seasonal bias in estimates of freshwater flow from the Delta to the San Francisco Estuary.

The seasonal bias suggests flows were overestimated during the summer months and underestimated during the winter. Estimates of Delta outflow use a measurement called net Delta outflow index (NDOI), which is determined by taking the amount of Delta inflow, from sources such as the Calaveras, Sacramento, and San Joaquin rivers,...

Fish monitoring surveys in the San Francisco Estuary net different numbers of different fish species depending upon when and how they sample.

According to a new study published in San Francisco Estuary and Watershed Science, even surveys that target the same part of the water column can come up with significantly different catches. The study’s authors analyzed decades worth of data from the California Department of Fish and Wildlife (CDFW) Fall Midwater...
