The scientists noted that on the northeastern side of Owens Lake, the Keeler Dunes transitioned during the last century from a “largely vegetated dune system” to one that releases more dust.

They have been found living along the vegetated banks of Osbaldwick Beck which runs through the park, following a seven-year project to improve the wildlife habitat in the area.

The researchers used satellite data to look for green, vegetated areas within dryland areas, indicating an oasis, and tracked changes over 25 years.

Crews will be installing steel girders — long boxes of reinforced concrete — over the freeway in order to build the vegetated bridge, according to Caltrans.

Crews will install girders over the freeway to support the crossing, a vegetated bridge that will reconnect wildlife habitat, officials said.
