2006 ROBERTSON RANCH EAST VILLAGE OPEN SPACE LAND MANAGEMENT PLAN Prepared report

INTRODUCTION A. Background The Robertson Ranch Master Plan area is approximately 398 acres of planned development located within the north-central area of the city of Carlsbad (Figure 1). Through the CEQA review for the Robertson Ranch Master Plan project, the project was determined to result in significant impacts to sensitive upland biological resources. As mitigation for these impacts, the two Robertson Ranch landowners are obligated to set aside for permanent conservation significant amounts of open space, including large tracts of native and restored Diegan coastal sage scrub (ʺDCSSʺ) habitat. This habitat conservation and revegetation provides for a habitat corridor running diagonally through the Robertson Ranch site from north-east to southwest, but also meanders throughout the hillsides of the property. The Robertson Ranch is owned by two separate entities, as follows: East Village - Calavera Hills II, LLC West Village - Robertson Family Trust This Robertson Ranch East Village Open Space Land Management Plan (ʺPlanʺ) constitutes the land management plan for the open spaces of the East Village only. The East Village open spaces subject to this Plan are identified as the East Village Habitat Conservation Area (ʺEVHCAʺ) (Figure 2). This is the area affected by the requirements of this Plan. This Plan is intended to provide guidance to the open space manager, to ensure the perpetual conservation and maximization of the biological resource values of the EVHCA. The EVHCA is being preserved in accordance with the requirements of the City of Carlsbad Habitat Management Plan (ʺHMPʺ), in concurrence with the City of Carlsbad, the U.S. Fish and Wildlife Service (ʺUSFWSʺ) and the California Department of Fish and Game (ʺCDFGʺ). The primary goal of this habitat conservation is to protect the habitat of the federally listed coastal California gnatcatcher, as well as other listed species and sensitive plant and wildlife species that are covered under the Multiple Habitat Conservation Plan (ʺMHCPʺ). A total of two (2) gnatcatchers have been observed to occupy the East Village preserve area in the survey (2002) by Merkel & Associates used to determine the preserve areas. To confirm the presence of coastal California gnatcatcher, a presence/absence survey shall be undertaken by long-term management entity within 60 days of officially accepting the property. The subject EVHCA constitutes the implementation of the

2008 Calavera Hills and Robertson Ranch Habitat Conservation Area (S031) Annual Report report

Lead author: Patrick McConnell
This report summarizes the management activities performed or overseen by the Center for Natural Lands Management (Center, CNLM) at the Calavera Hills and Robertson Ranch Habitat Conservation Area (HCA) during the management year beginning on October 1, 2007, and ending on September 30, 2008. This work plan has been developed from the guidelines for goals and objectives set forth in the Calavera Hills Phase II Final Habitat Management Plan (HMP) dated October 2002 (Planning Systems 2002), the Robertson Ranch East Village Open Space Land Management Plan (OSMP) (Planning Systems 2006), and the Robertson Ranch West Village Open Space Preserve Land Management Plan (Planning Systems 2007), of which all activities were agreed upon by the United States Fish and Wildlife Service (USFWS) and California Department of Fish and Game (CDFG).

2010 Calavera Hills and Robertson Ranch Habitat Conservation Area report

This work plan has been developed from the guidelines for goals and objectives set forth in the Calavera Hills Phase II Final Habitat Management Plan (HMP)(Planning Systems 2002), the Robertson Ranch East Village Open Space Land Management Plan (Planning Systems 2006) and the Robertson Ranch West Village Open Space Preserve Land Management Plan (Planning Systems 2007). These Habitat Management Plans have been reviewed by and agreed upon by the City of Carlsbad, United States Fish and Wildlife Service (USFWS) and California Department of Fish and Game (CDFG). The Center for Natural Lands Management (Center) holds conservation easements (since June 2006 for Calavera Hills Phase II, and February 2007 for Robertson Ranch East Village, and December 2007 for Robertson Ranch West Village Parcel 23C Phase I) on the Calavera Hills and Robertson Ranch Habitat Conservation Area (HCA) and performs or oversees the tasks identified in the three Habitat Management Plans (collectively HMP's). The HCA is comprised of seven parcels, commonly referred to as Village H, R, U, W, and X, Robertson Ranch East Village, and Robertson Ranch West Village PA 23C Phase I, the first phase of a two phase parcel recordation process. The Center has merged the funding and reporting for these two areas as we provided the developer a financial discount for selecting the Center to manage both properties. In other words, the funding for the Robertson Ranch areas is less than what we would normally charge had we not already received funding for the Calavera Hills Phase II areas. This will also simplify future budgetary, reporting, and planning considerations. 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. Unless otherwise stated, all tasks will be performed by Center's Preserve Managers Patrick McConnell and Jessica Vinje and Rangers Justin Trujillo, Zadok Othniel and Roberto Bejar. Summary of Tasks and Goals for the Management Year: - Maintain signs and existing fences - Install signage, smooth-wire fencing, and vegetation to limit pedestrian and vehicular access - Census and conduct habitat assessments of thread-leaved brodiaea (Brodiaea filifolia), and San Diego thornmint (Acanthomintha ilicifolia) - Continue to set up and monitor coastal sage scrub (css) long-term monitoring plots - C
