Climate Change Effects on Coastal Ecosystem Services: Ecological and Economic ImplicationsAnn Shellenbarger Jones

Technical Assistance funded by EPA through the Climate Ready Estuaries Program

overview of evaluation
Overview of Evaluation
  • SLAMM – model for habitat change due to sea level rise
  • HEA – habitat equivalency analysis
    • allows tradeoffs in habitat services over time
    • calculates costs associated with restoration
  • Combine - estimate ecological and economic impacts of habitat loss and restoration
  • Goal today – improve data sources for SLAMM
sample slamm draft cumberland county
Sample SLAMM – Draft Cumberland County
  • 2000 vs 2100
  • Gradual inundation
  • ? - wetland types, edge/middle dynamics
data gaps
Accretion

Vegetation Type and Condition

Erosion

Ponding

Ecological Services

Development Layer – in progress

Data Gaps
accretion
Accretion
  • Relying on Reed et al. 2008 / CCSP literature review.
  • No info for NJ bay marshes
  • Data are pre-2000
  • Salt/brackish – 4-5 mm/yr
  • Tidal Fresh – 10 mm/yr
vegetation
Vegetation
  • Type, %Cover, Condition
  • PSEG
  • National Vegetation Classification System
  • Interested in GIS layers
erosion
Erosion
  • SLAMM implements erosion based on fetch threshold
  • Default = 2 m/yr
  • Data needs: maps of erosion rates; information by marsh type, county, etc.
ponding
Ponding
  • Questions raised on sites, reasons for ponding
  • How to predict?
  • Dike data
ecological services
Ecological Services
  • Primary/secondary productivity
  • T&E or “key” species habitat
  • Carbon sequestration
  • Local research on sequestration?
  • Water quality impacts
  • Nitrogen, Phosphorus cycling
  • Data for scrub-shrub/forested wetlands
development
Development
  • Next iteration – development layer
  • Allows wetland migration to undeveloped land
  • Also – consider shore protection scenarios
