A canal that delivers vital water supplies from Northern California to Southern California is sinking in places. So are stretches of a riverbed undergoing historic restoration. On farms, well casings pop up like mushrooms as the ground around them drops.

Scat sniffer dogs tell York U researchers a lot about endangered lizards
Dogs can be trained to find almost anything (people, drugs, weapons, poached ivory) but one York University researcher had them detect something a little unusual - the scat of endangered blunt-nosed leopard lizards. The scat detection dogs helped biology PhD student Alex Filazzola discover not only scat, but the importance of shrubs in preserving lizard populations in the face of climate change.

NASA data show California's San Joaquin Valley still sinking
Since the 1920s, excessive pumping of groundwater at thousands of wells in California's San Joaquin Valley has caused land in sections of the valley to subside, or sink, by as much as 28 feet (8.5 meters). This subsidence is exacerbated during droughts, when farmers rely heavily on groundwater to sustain one of the most productive agricultural regions in the nation.

Highly contagious infection threatens endangered San Joaquin kit fox population
Endangered San Joaquin kit foxes face many threats to their survival, including loss of habitat and competition with non-native species such as the red fox. Now, scientists are rushing to save remaining fragile populations from a new danger - sarcoptic mange, a skin disease caused by mites.

Groundwater overuse has permanently reduced San Joaquin Valley's water storage ability
Decades of over-pumping groundwater have irreversibly altered clay layers in parts of California's Central Valley, causing the ground to sink and permanently reducing its capacity to store water, a new satellite remote sensing study shows.

California farm region plagued by dirty air looks to Trump
California's vast San Joaquin Valley, the country's most productive farming region, is engulfed by some of the nation's dirtiest skies, forcing the state's largest air district to spend more than $40 billion in the past quarter-century to enforce hundreds of stringent pollution rules.
