The authors looked at 36 vernal pools on two different geologic formations on a 5000-ha ranch in eastern Sacramento County, California. Their experiments found that removal of grazing reduced the duration of wetland flooding by an average of 50 days per year. Their simulations show that climate change could compound these impacts, potentially, leaving endangered fairy shrimp and tiger salamanders without enough time to mature before their temporary aquatic environments disappear. "Consequently, land managers can play an important role in climate change impacts, i.e. they can exacerbate or ameliorate, the local impacts of global change." Pyke adds. Conservationists may find that grazing is not always a negative factor, and it presents real opportunities to adapt to climate variability and climate change.
