Transcript and Presenter's Notes

Title: Planning tools


1
Planning tools
  • Working together to restore North Carolina's
    natural communities

2
EEP-CVS Collaboration
  • EEP wants to do a better job creating natural
    ecosystems.
  • CVS provides improved reference data, target
    design, monitoring, and data management and
    analysis

3
Where we are going
  • CVS is developing tools and data sources to
    facilitate planning of restoration activities and
    to evaluate their success.
  • New data sources and tools are being designed
  • Suggestions for new tools and increased
    functionality are.

4
Restoration protocol
  • Document reference conditions
  • Derive restoration targets
  • Design site-specific restoration plan
  • Implement the plan
  • Monitor change and assess success
  • Employ adaptive management

5
Target generation
  • Simple goal Deliver composition target based on
    the vegetation type most appropriate for the site
    and region.
  • Sophisticated goal Automated system that uses
    site information and reference plot data to
    predict vegetation composition.

6
Improving restoration targets
  • Crude species lists
  • Plot database linked to the National Vegetation
    Classification and the Natural Heritage Program
    documentation
  • High-resolution community classification with
    quantitative descriptions.
  • Dynamically generated targets

7
Ecological Groups
  • Mountain Vegetation
  • Montane upland forests
  • Montane open upland vegetation
  • Montane alluvial wetland vegetation
  • Montane nonalluvial wetland vegetation
  • Piedmont Vegetation
  • Piedmont upland forests
  • Piedmont open upland vegetation
  • Piedmont alluvial wetland vegetation
  • Piedmont nonalluvial wetland vegetation
  • Coastal Plain Vegetation
  • Coastal Plain upland forests
  • Coastal Plain upland open woodland vegetation
  • Coastal Plain alluvial wetland vegetation
  • Coastal Plain nonalluvial wetland vegetation
  • Coastal Fringe Vegetation
  • Maritime upland forests shrublands
  • Maritime open upland vegetation
  • Maritime nontidal wetland vegetation

Primary sources of data
  • Targeted communities
  • Mountain bogs
  • Piedmont alluvial forests
  • Pulse events with regional focus

24
  • Longleaf pine feasibility study
  • Few longleaf pine sites remain in original
    condition.
  • Restoration targets must be extrapolated from a
    limited number of reference stands.

25
  • Dataset
  • 188 plots across fall-line sandhills of NC, SC,
    GA
  • - All sites contained near-natural,
    fire-maintained groundlayer vegetation
  • - Soil attributes included for both the A and B
    horizon sand, silt, clay, Ca, Mg, K, P, S, Mn,
    Na, Cu, Zn, Fe, BD, pH, organic content, CEC, BS.

26
Step 1. Classification. Developed a
classification of the major vegetation types of
the ecoregion. Used cluster analysis with a
matrix of 188 plots x 619 species. Vegetation
types were seen to be differentiated with respect
to soil texture, moisture, nutrient status,
geography.
27
  • Step 2. Build model.
  • - Forward selection with linear discriminant
    analysis identified predictor variables.
  • Critical variables were Latitude, Manganese,
    Phosphorus, Clay, Longitude.
  • 75 of plots correctly identified to vegetation
    series. Typically 75 of plots within a series
    were correctly classified to community type.

28
  • Step 3. Select species.
  • Generate a list of all species in type (species
    pool) with frequency, mean cover values, and mean
    richness.
  • Randomly order the list
  • Compare species frequency to random number
    between 0 1, and if the random number is less
    than the proportion of plots the species is
    selected. Continue until the number in list of
    selected species equals the number predicted.

29
  • Summary of overall strategy
  • Identify biogeographic region and obtain
    predictive models.
  • Select pool of candidate species for a specific
    site based on range information.
  • Divide restoration site into environmentally
    homogenous areas, stratifying by topography and
    soil.
  • Use models to select species number and
    composition.
