North Pacific LCC

Coastal ecosystems have been identified by the International Panel on Climate Change (2007) as areasthat will be disproportionally affected by climate change. Recent sea-level rise projections range from 0.57to 1.1 m (Jevrejeva et al. 2012) or 0.75 to 1.9 m by Grinsted et al. (2010) and Vermeer and Rahmstorf(2009) by 2100, which are contingent upon the ambient temperature conditions and CO2 emissions. Sealevelrise projections for San Francisco Bay are 1.24 m by 2100 (Cayan et al. 2008). The expectedaccelerated rate of sea-level rise through the 21st century will put many coastal ecosystems at risk,especially those in topographically low-gradient areas.Sea-level rise response modeling was conducted at 12 tidal salt...
The aim of this USGS program is to provide site specific sea-level rise predictions to land managers through the intensive collection of field data and innovative predictive modeling. In 2009 and 2010, thousands of elevation and vegetation survey points were collected in salt marsh at 12 sites surrounding San Francisco Bay. The elevation data was synthesized into a continuous elevation model for each site, providing land owners valuable baseline data. This site hosts the project report, pages describing each of the 12 marshes visited in this study, and maps and GIS data for all of the marshes including high-resolution digital elevation models.
User Guide: Quick guide to choosing and using species distribution models for HCPs
Knowing where a species is found or may be found in the future is critical to developing a successful habitat conservation plan. This quick guide reviews correlation-based and process-based species distribution models and their uses in the context of HCPs. It also addresses considerations for evaluating species distribution models, using multiple models, and working with model uncertainty. Examples are provided.

FY2014There is increasing interest in climate change adaptation, particularly since the release of the Presidents Executive Order on Climate Preparedness in November, 2013, yet many field staff remain uncertain how to put adaptation into practice. Our goal with this project is to bridge the gap between the wealth of high-level climate adaptation guidance and the field staff who carry out specific regulatory processes, specifically Habitat Conservation Plans. Following best practices from the literature on linking science and management, we will begin with a focus on what people do rather than on the climate science. We will map the current HCP development and approval process in Region 8, identify where and how...
User Guide: Climate-informed reserve design
With HCPs, reserves are created as one means of mitigating take. This means they are designed to provide a target level of benefits for a particular species or set of species. This quick guide reviews approaches for designing and implementing reserves that address climate change impacts, vulnerabilities, and uncertainty. Examples are provided.

ScienceBase brings together the best information it can find about USGS researchers and offices to show connections to publications, projects, and data. We are still working to improve this process and information is by no means complete. If you don't see everything you know is associated with you, a colleague, or your office, please be patient while we work to connect the dots. Feel free to contact sciencebase@usgs.gov.
