I am a wetland ecologist interested in thresholds of stability and transitions between alternate stable ecosystem states. I also work to quantify and restore ecosystem functions and services.
Dr. David Cooper (left) and Athena Demetry (Sequoia NP Restoration Ecologist) discuss the merits of using this meadow as a reference site for Halstead Meadow.
These culverts drain Upper Halstead Meadow under the General's Highway. The culvert discharge has eroded a 6 m deep, 10 m wide gully, and is undercutting the highway. The highway and culverts were built in 1934.
This is Round Meadow, a reference site for Halstead Meadow. Athena Demetry (at left), the park Restoration Ecologist and Dr. David Cooper are looking at a channel flowing during peak runoff. Water is seen cascading over a headcut into the channel.
