Summary

We analyzed historical aerial photography and used dendrochronology to quantify long-term spatial and temporal patterns of narrowing and vegetation expansion, including native cottonwood (Populus fremontii) and non-native Russian olive (Elaeagnus angustifolia), along the largely unregulated Escalante River in Utah, USA. Our general study area was between the town of Escalante and Choprock Canyon, and we focused on two detailed study reaches within this broader area. The study reaches were in long, entrenched meander sections of river: an upper reach, Reach 1, was approximately 15 river kilometers (rkms) long and located between Sand and Boulder creeks within Grand Staircase Escalante National Monument; and a lower reach, Reach 2, was [...]
