Highlights
In the past few decades, conservation planning across the globe has shifted from single-species management to multispecies planning and ecosystem-based management as our understanding of ecological processes and appreciation of social-ecological systems has grown (Poff et al 1997, Poiani et al 2000)
We provide a particular focus on California rail populations and invasive Spartina extent at 4 tidal salt marshes in the southern reach of SF Bay where detailed studies of California rail ecology occurred (Fig. 1): Arrowhead (37°44.662′ N, 122°12.832′ W), Cogswell (37°28.119′ N, 122°8.877′ W), Colma (37°38.682′ N, 122°23.543′ W), and Laumeister (37°28.311′ N, 122°7.500′ W)
We note that the parameters were not significant (p = 0.908), including an interactive effect between invasive Spartina cumulative changes and remaining invasive Spartina matched our hypothesis that California rail population growth rates declined at a lower rate when a greater proportion of the marsh remained occupied by invasive Spartina
Summary
In the past few decades, conservation planning across the globe has shifted from single-species management to multispecies planning and ecosystem-based management as our understanding of ecological processes and appreciation of social-ecological systems has grown (Poff et al 1997, Poiani et al 2000). The criterion for success of ecosystem restoration is change from an existing undesired habitat condition toward a more desired condition and is often measured by a change in species composition, ecological function, or ecosystem service. How are these made and who gets to decide what is desired? Identifying who, or how, these desired future conditions are identified and measured is a nontrivial process Whether these conditions are identified through consensus, legal mandate, or personal fiat, the final stated outcome, along with any minimum prerequisites, can greatly influence the efficiency, expediency, or expense of management actions
