Article abstract: INTRODUCTION AND SUMMARY This work plan has been developed from the guidelines for goals and objectives set forth in the City of Carlsbad Preserve Management Plan (PMP) for the Carlsbad Oaks North Habitat Conservation Area (HCA) dated January 2005 (Tierra Data 2005) and as agreed to by the United States Fish and Wildlife Service (USFWS) and California Department of Fish and Game (CDFG). This annual work plan also includes additional management activities that the Center for Natural Lands Management (CNLM, referred to in-text as the Center) feels are appropriate to protect and maintain the natural resources at the HCA in perpetuity. The HCA covers 326 acres, of which 108.4 acres are located within a conservation easement (CE) on lands owned by the County of San Diego. The CE was transferred to the Center in November of 2005. The Center received funds to manage the CE portion in May of 2006 at which time management activities commenced. The Center received fee title for the remaining 219.6 acres from the previous owner, Techbilt Construction Corporation (Techbilt), in March of 2007. The purpose of this work plan is to identify the tasks and budget required to complete the management activities for the upcoming management year that will begin on October 1, 2010 and end on September 30, 2011. This is the fifth annual work plan submitted for this HCA since receiving the original CE portion in May 2006. Unless otherwise stated, all tasks will be performed by the Center's Area Manager, Markus Spiegelberg, Center HCA Managers Patrick McConnell and Jessica Vinje.
