Wetlands
Wetlands

  • Jurisdictional Wetlands Assessment

  • Boundaries mapped using remote sensing and GPS Technology

  • Data Collected

    • Cover type - (Cowardin)

    • Acreage

    • Five dominant vegetative species

    • Dominant invasive plant species

    • ORAM Scores


Jurisdictional wetlands assessment
Jurisdictional Wetlands Assessment

  • Wetlands assessed for size, location, and quality

  • 74 individual wetlands

  • 482.9 acres in total

  • Most high quality, Category 3

  • Approximately 100 acres of low quality wetlands


Wetlands impacts
Wetlands Impacts

  • Invasive Plant Species

  • Altered Hydrology


Results water quality
Results - Water Quality

High quality headwater streams concentrated on western end of property

Main channel of Pond Brook is highly degraded



Minimum value typically associated with WWH conditions

Pond Brook IBI

Downstream

Upstream


Diagnosis
Diagnosis ….

  • Fish and macroinvertebrate communities within Pond Brook are unhealthy. Causes include…

  • 1. Poor habitat

  • 2. Basic Water Quality

  • 3. Synergistic effect of water quality and habitat (no riffles and100%open canopy).


Ecological restoration opportunities
Ecological Restoration Opportunities

  • Approximately 16,000 linear feet of degraded stream corridor

  • Approximately 100 acres of low quality wetlands suitable for restoration


Ecological restoration costs
Ecological Restoration Costs

  • Stream Restoration $125/foot x 16,000 feet = $2,000,000

  • Wetlands Restoration $10,000/acre x 100 acres = $1,000,000

  • Total projected costs = $3,000,000
