Book Description
This annotated bibliography documents literature addressing the design and implementation of vegetation monitoring. It provides resources managers, ecologists, and scientists access to the great volume of literature addressing many aspects of vegetation monitoring: planning and objective setting, choosing vegetation attributes to measure, sampling design, sampling methods, statistical and graphical analysis, and communication of results. Over half of the 1400 references have been annotated. Keywords pertaining to the type of monitoring or method are included with each bibliographic entry. Keyword index.

Book Description
This technical reference applies to monitoring situations involving a single plant species, such as an indicator species, key species, or weed. It was originally developed for monitoring special status plants, which have some recognized status at the Federal, State, or agency level because of their rarity or vulnerability. Most examples and discussions in this technical reference focus on these special status species, but the methods described are also applicable to any single-species monitoring and even some community monitoring situations.We thus hope wildlife biologists, range conservationists, botanists, and ecologists will all find this technical reference helpful.

Book Description
Southern California shrublands are threatened by nonnative European annual grasses, which contribute to substantial fragmentation and loss of these ecologically important communities. Both natural and anthropogenic disturbances provide opportunities for competitive exotic herbaceous species to colonize in gaps in shrublands and overtake native grasses and shrubs. Remote sensing using moderate resolution imagery can provide a spatially comprehensive, cost-effective, and repeatable approach to monitor the establishment and expansion of nonnative herbaceous cover into sensitive habitats, and provide the potential for detecting native herbaceous cover where it occurs in high fractions. The underlying goal of this study is to better understand the temporal, spectral, and spatial characteristics of herbaceous vegetation in California shrublands in the context of effectively mapping and monitoring herbaceous vegetation cover using remote sensing methods. Chapter 2 provides the details of the phenological response and spectral properties of native and nonnative herbaceous cover, based on plot-based fieldwork conducted in CSS habitat in the San Diego National Wildlife Refuge (SDNWR). High temporal resolution field spectroscopic data were shown to be useful for determining when native and nonnative herbaceous vegetation in CSS are most spectrally separable in the course of a growing season. In Chapter 3, intraannual remote sensing methods are explored to map herbaceous cover fraction in shrublands. Optimal discernment of herbaceous cover was found using single-date imagery timed in the early summer months (early June in 2010); fractional cover of growth forms was mapped with errors of 0.08 or less. Chapter 4 investigates the stability and reliability of cover fractions modeled using a multitemporal remote sensing approach. MESMA applied to three dates (2008, 2010, and 2011) of SPOT imagery was used successfully to model growth form fractions over a large extent of shrubland vegetation with low individual and overall error. Findings from this study indicate that MESMA applied to moderate resolution imagery timed to maximize spectral differences between growth forms is an effective approach for quantifying changes in fractional cover that exceeds ten percent, providing a way to delineate and quantify herbaceous invasions and expansions following disturbance or succession.
