How to Use This Calculator
  1. Enter Survey Area (acres) and select Habitat Type (upland, wetland, riparian, etc.).
  2. Choose Target Taxa (plants, birds, reptiles, mammals, invertebrates) and Number of Target Species.
  3. Set Survey Seasons needed (1-4) based on species biology and permit requirements.
  4. Toggle Habitat Assessment to include a full HCP-quality habitat evaluation.
  5. Review Total Survey Cost ($) to scope the biological survey budget for Section 7 or 10 consultations.

What each input means

Survey area (acres)
Total area requiring biological survey.
Habitat type
0 = Grassland, 1 = Forest, 2 = Wetland/riparian, 3 = Desert/scrub, 4 = Aquatic/stream.
Target taxa
0 = Plants, 1 = Birds, 2 = Mammals/bats, 3 = Reptiles/amphibians, 4 = Fish/aquatic inverts.
Target species count
Number of listed species to survey for.
Survey seasons
Number of seasonal survey windows required by protocol (e.g. spring + fall).
Include habitat assessment (0/1)
Set to 1 to include habitat quality assessment and mapping.

What each result means

Total survey cost ($)
Complete cost for biological surveys, report, and analysis.
Field survey cost ($)
On-site species detection and observation work.
Habitat assessment cost ($)
Habitat mapping and quality evaluation.
Report & desktop review ($)
Literature review, database queries, and report writing.
Lab/analysis cost ($)
Specimen ID, acoustic analysis, or eDNA processing.
Total field days
Estimated person-days of field work across all seasons.
Timeline (months)
Project duration accounting for seasonal survey windows.
Cost per acre ($)
Total survey cost divided by site acreage.

How this is calculated

Worked example, using the default values

  1. Identify Input Parameters
    4 parameters
    Survey area (acres) = 20, Habitat type = 1, Target taxa = 1, Target species count = 2 = 6 input(s) provided
  2. Calculate Total survey cost
    Total survey cost = coreSurveyCost + habitatAssessmentCost + desktopReview + reportCost + labCost
    26940 = $26,940
  3. Calculate Field survey cost
    Field survey cost = (taxaBase + fieldCost) * speciesMultiplier * seasonMultiplier * habitatMult
    17940 = $17,940
  4. Calculate Habitat assessment cost
    2600 = $2,600
