Environmental Change Network: Current and Future Zonation PrioritizationZonation is a spatial conservation planning software tool that can take into account multiple species to create a hierarchical prioritization of the landscape. This is in contrast to other spatial conservation planning tools which may require predefined conservation targets or areas. Here, we used 199 California landbirds along with Zonation’s “core-area” algorithm to prioritize the California landscape. Species were weighted according to the California Bird Species of Special Concern criteria and probability of occurrence was discounted by distribution model and climate model uncertainty surfaces.The dataset provides priority areas for “current”...

We developed and delivered a training curriculum for two courses in species distribution modelingthat included sample data, multimedia, and module lesson plans. Target audiences will be planners, managers, and technical analysts (GIS Specialists). Final course content and curriculum are availablethrough partner websites and the California Climate Commons.
These maps display the magnitude of projected future climate change in relation to the interannual variability in late 20th century CA climate. The maps show the standardized Euclidean distance between the late 20th century climate at each pixel and the future climate at each pixel. The standardization puts all of the climate variables included on the same scale and down weights changes in future climate which have had large year to year variation historically. Warmer colors indicate greater climate change and cooler colors indicate less extreme climate change.

This project uses existing decision support tools (DST) in a scenario planning analysis for the South Bay Salt Ponds Restoration Project (SBSPRP) as a case study that other bayland managers can reference for best practices for using these DSTs for adaptation planning. Through substantial investment by the CA LCC and other partners, we have developed a set of DSTs that support conservation decision-making for San Francisco Estuary ecosystems (www.prbo.org/sfbayslr (link is external) and (link is external)). These tools are ideally suited to support climate-smart restoration planning for shorebird and marshbird habitat. However, the utility of these tools could be promoted through their application in an actual case...

Priority areas for conservation of tidal marsh birds given current and future environmental conditions. Maps were created using Zonation, a spatial conservation planning software tool that can take into account multiple species and scenarios to create a hierarchical prioritization of the landscape.The current (2010) and future (2030-2110) prioritization is based upon distribution and abundance models for five tidal marsh bird species which utilized avian observation data (2000 - 2009), a marsh accretion model, and physical variables (e.g. salinity, distance to nearest channel, slope, etc). Values represent the rank in which pixels were removed from the landscape using Zonation Conservation Planning software with...

Marsh accretion was modeled by ESA PWA using the Marsh-98 model, described here. The model assumes that rates of marsh plain elevation change depend on the availability of suspended sediment and organic material, water depth, and duration of inundation periods. If enough suspended sediment is available, then tidal marsh elevations can keep pace with increased inundation. Model outputs were linearly interpolated in 10-cm increments for starting elevations ranging from -3.7 to 1.7 m (relative to mean higher high water, or MHHW), and applied to a composite 5-m elevation grid (see below) for SF Bay. Results for each possible combination of projected sea level rise, sediment and organic material availability, and target...

The CA Academy of Science and Point Blue Conservation Science conducted a systematic analysis of uncertainty in modeling the future distributions of ~50 California endemic plant species and ~50 California land birds, explicitly partitioning among 5 alternative sources of variation and testing for their respective contributions to overall variation among modeled outcomes. They mapped the uncertainty from identified sources, which can guide decisions about monitoring, restoration, acquisition, infrastructure, etc., in relation to climate change.

This business plan provides the rationale for developing an Environmental Change Network for the California Landscape Conservation Cooperative. This plan will illustrate important potential uses of the network and its data and show how these uses will increase the efficiency and efficacy of adaptation planning and implementation efforts. We will demonstrate how the value of the network will be greater if implemented sooner. We also show how the proposed network will integrate with larger scale efforts currently ongoing at the national level and how it can also inform smaller scale efforts at local levels. The specific objectives of this business plan are to:• Provide a rational for the further development and implementation...
Full Title: Environmental Change Network: Current and Projected VegetationThe current vegetation layer is derived from the vegetation map developed as part of the California Gap Analysis project. The derivation takes the California Wildlife Habitat Relationships (CWHR) habitat classification provided in the California Gap Analysis layer, generalizes the classes to a set of broader habitat types, and rasterizes it at 800 meter resolution.The future vegetation layers for both the GFDL and CCSM GCM models are derived using a random forest model of the vegetation classification. The original CWHR classification has been generalized to 12 classes for ease in modeling. Inputs to the model include eight bioclimatic variables...

Most natural resource managers, planners and policy makers are now dependent upon spatially explicit environmental suitability and spatial allocation analyses to inform policy and management decisions. However, staff across agencies has been unable to stay current on understanding and applying these new data, tools and analyses. Currently, this information may be underutilized or used inappropriately, which could result in poor decisions. Two training curricula were developed – one for managers and one for GIS analysts – on current best practices for developing and using spatial information to support conservation decision making. The training materials are open-source and widely distributed to California LCC stakeholders.

This website provides information on the project’s effort to establish a network of environmental monitoring stations within the boundaries of the California LCC. Users of this web portal can view predicted distributional changes in landbird, habitat, and climate under future climate conditions and find out general information on the progress and evolution of the network.
Densities for five key tidal marsh-dependent bird species were modeled using boosted regression trees (Elith et al. 2008). The models are able to fit non-linear functions between environmental variables and the presence/absence or density of a species. Map values represent the probability of occurrence of a species or the density (birds/ha). Higher values in a map indicate a higher likelihood that a species will be present at a site. Bird species modeled: Common yellowthroat, black rail, clapper rail, marsh wren, song sparrow. Model outputs: Probably of occurrence, density (birds per hectare)

This project developed a foundation for monitoring environmental change by identifying where and what to monitor in order to evaluate climate-change impacts. Phase 1 focused on landbirds, however a framework will be developed that recommends standardized monitoring for other taxa and environmental attributes. Phase II Deliverables produced as part of this proposed work include a Business Plan that 1) refines site selection by developing a decision model in combination with analyses of sites (or clusters of sites) arrayed by climate space, 2) works with the LCC science committee, Joint Ventures, and other partners to choose a manageable number of core monitoring variables, 3) develops and/or adopting existing protocols...

The development of sophisticated species distribution modeling techniques provides an opportunity to examine the potential effects of climate change on bird communities. Using these modeling approaches, we are relating bird data to environmental layers to generate robust predictions of current (1971–2000) and projected future species occurrence. Future bird distributions are based on regional climate model projections for the periods 2038–2070 (IPCC Scenario A2). Bird species distributions were created using the Maxent modeling technique: Maxent (Phillips et al. 2006), which is able to model non-linear responses to environmental variables. Map values represent the predicted habitat suitability; the higher the values,...

The Future San Francisco Bay Tidal Marshes Climate Smart Planning Tool is a web application that enables the user to view and query maps made with projected tidal marsh elevations, vegetation changes, five tidal marsh-dependent bird species distribution probabilities and densities, and current and future conservation prioritization. The map-making tool presents the user with current and future maps side by side, and allows for choices of higher and lower levels of sea level rise, sediment availability, and organic material accumulation. The purpose for using the tool is to support an understanding of how sea level rise may change the extent of tidal marsh habitat and bird species distribution over the next 100 years,...
