Difference between revisions of "Core Monitoring Plan"

This document describes a general plan and framework for the development of a core monitoring program for the GCDAMP during federal fiscal years 2011 through 2015. Detailed core monitoring plans with explicit methodologies for each resource category will be developed as outlined in this plan over the next several years. The proposed process is consistent with the strategies and objectives described in the Grand Canyon Monitoring and Research Center’s (GCMRC) Strategic Science Plan (U.S. Geological Survey, 2007a) and Monitoring and Research Plan (U.S. Geological Survey, 2007b), and the GCDAMP Strategic Plan as amended by the Adaptive Management Work Group at their August 2003 meeting (AMWG written comm., 2003, hereafter cited as GCDAMP, 2003).

Monitoring is a fundamental requirement of the adaptive management process (Walters, 1986; Walters and Holling, 1990). The Department of the Interior (DOI) Adaptive Management Technical Guide (Williams and others, 2007) identifies four primary purposes for monitoring within an adaptive management program:

• 1. To evaluate progress towards achieving management objectives
• 2. To determine resource status in order to identify appropriate management action
• 3. To increase understanding of resource dynamics via the comparison of predictions against field observations
• 4. To enhance and develop models of resource dynamics as needed

In 1995, the Grand Canyon Monitoring and Research Center (GCMRC) was created to fulfill the mandate in the 1992 Grand Canyon Protection Act for the establishment and implementation of a long-term monitoring and research program to ensure that Glen Canyon Dam is operated in a manner that protects the values for which the Grand Canyon National Park and the Glen Canyon National Recreation Area were created.

Since its inception, many of the GCMRC activities have focused on continuing certain monitoring tasks previously established under the Glen Canyon Environmental Studies program (termed here as “Legacy” monitoring), conducting field experiments, and developing technologies in support of development of a core monitoring program. Implementation of a long-term core monitoring program will require a significant commitment of qualified personnel to ensure that the program is implemented in a sustainable and timely manner. With a few exceptions, much of the data collection is proposed to be performed by cooperating agencies and contractors as discussed below; however, some monitoring, such as quality of water and sediment monitoring that has historically been part of the USGS mission, is proposed to continue internal to the GCMRC and the Water Resources Discipline within USGS.
