Scarification Soil Disturbance Percent

Audit observed scarification point disturbance with physical representation weights and caller upper limit; no beneficial soil-preparation assumption or ecological/regulatory suitability certification.

Description

Scarification disturbance can be estimated from observed points with unequal area representation.

Scarification disturbance can be estimated from observed points with unequal area representation. A caller threshold defines the audit rather than an assumed ecological benefit.^[1]

When to use Scarification Soil Disturbance Percent

Use this tool to audit observed scarification point disturbance with physical representation weights and caller upper limit; no beneficial soil-preparation assumption or ecological/regulatory suitability certification.

Gather the tree inventory, plot measurements or model parameters. Check diameter, area, time and moisture conventions; keep paired observations aligned.

How to use Scarification Soil Disturbance Percent and understand its results

Gather the tree inventory, plot measurements or model parameters. Check diameter, area, time and moisture conventions; keep paired observations aligned.
Enter disturbedPointFlags, representedPointAreasM2, callerMaximumDisturbedFraction using the field table and calculation rules, then run the tool.
Read areaWeightedSoilDisturbancePercent, aboveCallerDisturbanceLimit. The explanation below defines the units, signs, ordering and any flags or placeholder values.
If the tool reports an input issue, correct the values and run it again. Apply the stated assumptions when interpreting a successfully returned result.

Input field	Meaning	Value type; see rules below	Requirement
disturbedPointFlags	Disturbed point flags	list of number	Required
representedPointAreasM2	Represented point areas m2	list of number	Required
callerMaximumDisturbedFraction	Caller maximum disturbed fraction	number	Required

Pair binary observed flags with positive m² weights and a maximum fraction in [0,1]. Return area-weighted disturbance percent and a strict above-limit flag; equality is allowed.

Paired lists must be nonempty and have equal lengths.

disturbed share=Σbinary disturbance × represented area/Σarea

Units, indexing, boundary conditions and exceptional cases are defined in the calculation rules above.

Output field	Meaning	Value type
areaWeightedSoilDisturbancePercent	Area weighted soil disturbance percent	number
aboveCallerDisturbanceLimit	Above caller disturbance limit	boolean

Limitations and assumptions

Sampling and policy are supplied. The result does not establish suitability or regulatory compliance.

Numeric inputs and returned numeric values must be finite; an unrepresentable returned value produces an error. Numeric lists are limited to 100,000 entries; the rules above may require smaller limits. Missing required fields, extra fields, wrong value types and violations of the calculation rules are input errors. A successfully returned false flag is an evaluated outcome; its meaning is explained above.

Alternative or Complementary methods

Use Skid Trail Density Percent Area: Account supplied trail strip areas and independently measured overlap before computing harvested-area occupation; no coordinate footprint construction or simple summed-overlap cover assumption. For a complementary task, use Maximum Rut Depth Operational Limit Checker: Audit measured rut-depth exceedances and represented trail-length fraction under caller operational limit; equality is allowed and no ecosystem/access safety or regulation is embedded.
