Technical Assistance funded by EPA through the Climate Ready Estuaries Program


Overview of evaluation
Overview of Evaluation Ecological and Economic Implications

  • 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 Ecological and Economic Implications

  • 2000 vs 2100

  • Gradual inundation

  • ? - wetland types, edge/middle dynamics


Data gaps

Accretion Ecological and Economic Implications

Vegetation Type and Condition

Erosion

Ponding

Ecological Services

Development Layer – in progress

Data Gaps


Accretion
Accretion Ecological and Economic Implications

  • 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 Ecological and Economic Implications

  • Type, %Cover, Condition

  • PSEG

  • National Vegetation Classification System

  • Interested in GIS layers


Erosion
Erosion Ecological and Economic Implications

  • 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 Ecological and Economic Implications

  • Questions raised on sites, reasons for ponding

  • How to predict?

  • Dike data


Ecological services
Ecological Services Ecological and Economic Implications

  • 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 Ecological and Economic Implications

  • Next iteration – development layer

  • Allows wetland migration to undeveloped land

  • Also – consider shore protection scenarios
