Global Warming has unexpected effects on ranges

A new study shows that instead of heading for higher elevations as the climate warms up, some plants and insects are shifting their ranges downhill, toward water.

Science Mag
study area: Northern half Ca
pulled vegetation records from 1930's started during great depression
compared with veg records more recent
many plant species ranges had moved downhill by 80 meters/240 feet

conservationists take heed
(that's my editorial)

most evidence re global warming is about temperature, not precip
plant communities may change direction of migration depending on where precip falls
