Volume 1 of the MSP is intended to be an operational document, while Volume 2 contains the functional sections and Volume 3 contains more technical information. Vol. 1 Volume 1 includes an overview of the MSP, approach and rationale for Overview & categorizing and prioritizing species and vegetation communities and for Approach developing management goals and objectives, characterization of the MSPA, MUs, and threats/stressors, and a description of databases and the implementation process. Vol. 2 Goals & Volume 2 includes regional and MU goals and objectives for species and Objectives vegetation communities, the prioritized timeline for implementation, and management goals and objectives for regional threat and stressor management. Vol. 3 Volume 3 contains the supporting documents that are part of and/or were used to Supporting develop the MSP. These include species profiles, additional methodological Documents details and definitions, and the implementation plan format. 1.1 GUIDE TO VOLUME 3 The sections included in Volume 3 provide supporting documents for the MSP. Section 1.0 provides the introduction and guide to Volume 3. Section 2.0 provides Species Profiles for MSP species that were used to develop goals and objectives. Section 3.0 includes a list and links to available best management practices (BMPs) for use in implementing the MSP management objectives. Section 4.0 includes the Implementation Plan (IP) format. Section 5.0 includes MSP detailed definitions. At the end of Volume 3 is Appendix 3A which includes the References for all three volumes. This same appendix is included in Volumes 1 and 2. Vol. 3, P. 1-1 Management Strategic Plan, Version 08.27.2013 Section 2.0 Species Profiles 2.1. Overview See Vol. 1, Section 2.4 for additional information on species profiles. Species profiles were developed for Orcutt’s spineflower, short-leaved dudleya, southwestern pond turtle, western burrowing owl, San Diego ambrosia, golden eagle, coastal cactus wren, sticky dudleya, small-leaved rose, coastal California gnatcatcher, and southern mule deer. Additional species will be added in future versions of the MSP. Vol. 3, P. 2-1 Volume 3, Section 2.0 2.2.

Special considerations: This species is considered to have reduced potential for recovery given that there are few populations, little remaining suitable habitat and a high risk of threats2. BMPs have been developed by the U.S. Navy to effectively expand populations and to establish new populations5,6.Recommendations are to eliminate non-native invasive plants and duff from areas with suitable habitat to see if there may be re-emergence of this species in new locations, given that seeds are likely to be long-lived1,5,6. Before seed supplementation is used for restoration, invasive non-native plants should be managed for at least two years of suitable growing conditions to determine if there are viable seeds remaining in soil.
