How to Use This Calculator
  1. Enter the restoration area in hectares and select the restoration method.
  2. Input existing coral coverage percentage and average depth.
  3. Set the distance from shore (access costs increase with distance).
  4. Review total project cost and cost per hectare for budget planning.
  5. Use coral fragments needed and nursery cost estimates for procurement planning.

What each input means

Restoration Area
Total reef area to be restored in hectares.
Restoration Method
1 = Coral Gardening/Fragmentation, 2 = Larval Seeding, 3 = Artificial Substrate, 4 = Comprehensive (all methods).
Existing Coral Coverage
Current live coral coverage on the site. Lower coverage = more restoration needed.
Average Depth
Average depth of the restoration site. Deeper sites increase diving costs.
Distance from Shore
Distance from nearest boat launch to the restoration site.

How this is calculated

Worked example, using the default values

  1. Identify Input Parameters
    4 parameters
    Restoration Area = 2, Restoration Method = 1, Existing Coral Coverage = 15, Average Depth = 8 = 5 input(s) provided
  2. Calculate Total Project Cost
    Total Project Cost
    827075 = $827,075
  3. Calculate Cost per Hectare
    Cost per Hectare
    351038 = $351,038
  4. Calculate Coral Fragments Needed
    Coral Fragments Needed
    50000 = 50000
  5. Calculate Nursery Setup Cost
    Nursery Setup Cost
    30000 = $30,000
