Wolf populations have been monitored in Yukon-Charley Rivers National Preserve (YUCH) from March 1993 to present. Beginning October 2005 the project was incorporated into CAKN Vital signs monitoring program. While the primary objectives of wolf monitoring will be to track the distribution and abundance of wolves, a variety of accessory data will be obtained in the monitoring process that are likely to be valuable for wildlife management and research.

Wolves are a species specifically identified in the enabling legislation and management objectives of all three CAKN parks (U. S. Congress 1980). While the primary objectives of wolf monitoring was to track the distribution and abundance of wolves, a variety of accessory data was obtained in the monitoring process that is valuable for wildlife management and research. The body of data on wolf populations in Alaska parks is of great value in developing scientific models of predator/prey systems. These data are used to determine and possibly mitigate impacts of wolf control activities outside...

This report focuses on monitoring the wolf population that utilize Yukon-Charley Rivers National Preserve (YUCH). Wolves are of great importance to people from both consumptive and non-consumptive viewpoints, and to the ecosystem as a whole. From a monitoring standpoint, wolves are considered to be good indicators of long-term habitat change within park ecosystems because they depend on healthy populations of large ungulate prey, which in turn respond to vegetation, weather and other habitat patterns across the entire landscape. As a top predator, wolves can play a key role in influencing...

The purpose of this survey was to estimate the moose population size, and sex/age composition for the Yukon River corridor with YUCH. Moose population information is needed by Preserve and state wildlife managers for monitoring long-term population trends and to make informed decisions regarding proposed changes to moose hunting regulations for this area.

This document introduces a moose monitoring protocol for the Central Alaska Network (CAKN). The network comprises Wrangell-St. Elias National Park and Preserve, Denali National Park and Preserve and Yukon-Charley Rivers National Preserve. This Protocol provides the rationale and objectives for monitoring of moose in this network, and specific instructions for implementing the monitoring program in the six Standard Operating Procedures contained in Appendix B.
