  • An Ecosystem Services Valuation of a Restored

    Kissimmee-Okeechobee-Everglades Watershed in the Face of Sea Level Rise

    ACES 2012 Workshop Dec 10, 2012

    ESV: Why the Controversy: Everglades Case Study

    Arthur R. Marshall Foundation 2012 Summer Interns:

    Mary Crider, Kyle Dollman, Danielle Koushel, James K.

    OConnell, and Max Wallace

  • Introduction

    Objectives Analyze CERP & CEPP as a Counter-Measure to Sea

    Level Rise (SLR)

    Complete an Ecosystem Service Valuation (ESV) for the Kissimmee-Okeechobee-Everglades Watershed

    Illustrate the value of the areas in the Everglades threatened by SLR

    Purpose Bring awareness to ESV as an important tool

    Encourage managers and decision-makers to consider SLR in public works projects

  • Sea Level Rise

    Preparing for Uncertainty

  • Sea Level Rise

    USACE, E.C. 1165-2-212, Figure B-11,

    2011

    SLR is caused by thermal

    expansion and glacial melting

    From 1961 to 2003, Global

    Mean Sea Level (GMSL) rose at

    an average rate of 0.017in/yr (a

    total of 3 inches)

    From 1993 to 2003, the average

    rate of increase was 0.12in/yr

    The expected range of SLR by

    2060 in South Florida is 9-24 in

    Most of FLs utility infrastructure

    is underground/coastal and at

    risk

    CERP & CEPP as a Counter-Measure to SLR

    1. Lodge, 2010; 2. Mitsch, et al, 2010

    Problems/Issues of

    SLR

    How CERP/CEPP are addressing them

    Salinization of

    Aquifers

    Increased freshwater flow will displace incoming saltwater. This is vital to protecting South

    Florida drinking water supplies.

    Decreased flood

    control capabilities

    The placement of pumps and flood control devices along with an increased freshwater head

    will improve the ability to discharge flood waters.

    Decreased storm

    protection

    A restored flow will improve the health of the wetland ecosystem which will allow it to

    effectively hold stormwater. Mangrove forests also act a physical barrier to storm surges

    and high winds.1

    Saltwater inundation

    of coastal wetlands

    Restored sheet flow will decrease the salinity of coastal wetlands and bring more detritus to

    the coast.

    Increased

    degradation of peat

    Mangrove forests will be encouraged by this increased deposition of organic matter. Peat

    deposits will form at a rate that will counteract the degradation from saltwater. 1

    Loss of carbon

    sequestration

    This tidal marsh and mangrove forests will sequester carbon.2

    Threatened natural

    habitats and species

    The resulting physical barrier will act as a primary defense against SLR.

    Definitions, Functions, and Examples

    functioning ecosystem

    habitat, production,

    and cultural and

    informational functions

  • Regulation Services Ecosystem Service Function Everglades Example Scale

    Regulation Services - The capacity of ecosystems to maintain essential ecological processes and life support systems

    Gas regulation Balances atmospheric gas

    concentrations

    Wetlands produce CH4 and release 20% of that

    to the atmoshphere1 Global

    Carbon Sequestration Stores carbon from natural and

    anthropogenic sources

    Through deposition of biomass, the Everglades

    wetlands store carbon1 Global

    Climate regulation

    Controls temperature,

    precipitation, and local weather

    patterns

    The evapotranspiration and rainfall in the

    Everglades are components of hydrologic

    patterns in all of South Florida2

    Global

    Disturbance regulation

    Ecosystem resilience to floods,

    storms, and anthropogenic

    perturbations

    Freshwater marsh vegetation naturally stores

    storm water and mangroves provide a physical

    barrier to hurricanes3

    Water flow regulation Timing and distribution of surface

    and groundwater flow

    Sheet flow maintains the ridge and slough

    Erosion control and

    sediment retention

    Reduces the rate at which soil is

    lost from the landscape

    Nutrient cycling and

    regulation

    ecosystem is important to convert nutrients to a

    usable form
