Corridor Single Gap Clearance

Compare a measured corridor gap with an explicitly supplied inclusive maximum without choosing a species-specific connectivity threshold.

Description

Compare one supplied corridor gap with a supplied maximum.

Conservation observations depend on sampling effort, specimen provenance, spatial precision and the population being assessed. Survivors among assessed plants differ from survivors among all planted plants. Coordinate rounding or cell assignment changes a display location without guaranteeing protection, and a time-gap threshold does not establish independent observations.

Compare one supplied corridor gap with a supplied maximum.

When to use this tool

Use Corridor Single Gap Clearance when you already have measuredGapWidth, maximumPermittedGap and need to compare one supplied corridor gap with a supplied maximum.

How to use the tool and how it works

  1. Enter measuredGapWidth, maximumPermittedGap. Use the units and conventions below.
  2. Run the tool. Correct any format, range, or cross-field input error before interpreting the output.
  3. Read margin, withinSuppliedGap. Inspect withinSuppliedGap before interpreting the associated values.

Require both widths>=0; margin=maximum-measured, within=measured<=maximum.1

Limitations and assumptions

  • Equality passes the scalar comparison. No species movement, connectivity, legal limit, corridor suitability or conservation outcome is established.
  • Inputs must satisfy both the field types and the cross-field conditions above. Invalid input causes an error; a successful false flag or documented placeholder is a different result.
  • Numeric calculations use binary floating point unless exact decimal-integer arithmetic is explicitly stated. No hidden measurement tolerance or decimal rounding is added; nonfinite or out-of-contract results are rejected. Numeric signed-zero results are exported as zero.

Alternative or Complementary methods

Review original field records, specimens, survey design and location-access requirements. Use the complete ecological and spatial method for population or protection decisions; local rates, interval flags and source-qualified labels do not supply it.
