Abstract

Headwater streams differ in susceptibility to debris flows and thus in importance as wood and sediment sources for larger rivers. Identifying and appropriately managing the most susceptible headwater streams is of interest. We developed and illustrated a method to delineate alternative aquatic conservation emphasis zones (ACEZs) considering probabilities for traversal by debris flows from headwater to fish-bearing streams. When ACEZs were substituted for currently prescribed riparian-management zones on non-fish-bearing streams, the total area decreased on federal lands but increased on other ownerships. Landscape-level outcomes, including wood delivery, can be evaluated over broad spatial extents under different policies using ACEZs.
