Heart Rot Column Height From Conk Position Estimator
Reconstruct independently assessed rot extents relative to observed conk positions, not inferring hidden decay from conk height alone or tree stability. Caller independently verifies units, applicability and matching conditions; no operational recipe, safety certification, causal efficacy or legal/resource classification is inferred.
Description
A rot-column estimate needs independently established extents above and below a conk location.
A rot-column estimate needs independently established extents above and below a conk location.1
A visible conk alone does not supply the internal decay boundaries needed for a length estimate. Use this tool to calculate heart rot column height from conk position estimator from the supplied measurements and assumptions.
When to use Heart Rot Column Height From Conk Position Estimator
Use this tool to calculate heart rot column height from conk position estimator from the supplied measurements and assumptions. Establish the species/site, survey protocol, units, sampled area or exposure, and the independently chosen reference or model.
How to use Heart Rot Column Height From Conk Position Estimator and understand its results
- Establish the species/site, survey protocol, units, sampled area or exposure, and the independently chosen reference or model.
- Enter observedConkHeightM, callerIndependentlyMeasuredRotBelowConkM, callerIndependentlyMeasuredRotAboveConkM, observedTreeHeightM, using the field meanings and rules below, then run the tool.
- Read assessedRotColumnLowerM, assessedRotColumnUpperM, assessedRotColumnLengthsM. Interpret the fields using their units, signs and evidence conventions below.
- If input validation fails, correct the reported field and run again. Before applying the result, check reference scope, model assumptions and any missing evidence or placeholder values.
| Input field | Meaning | Value type | Requirement |
|---|---|---|---|
| observedConkHeightM | Observed conk height m | list of number | Required |
| callerIndependentlyMeasuredRotBelowConkM | Caller independently measured rot below conk m; caller assertion or measurement requiring independent evidence | list of number | Required |
| callerIndependentlyMeasuredRotAboveConkM | Caller independently measured rot above conk m; caller assertion or measurement requiring independent evidence | list of number | Required |
| observedTreeHeightM | Observed tree height m | list of number | Required |
Enter nonempty aligned nonnegative conk height and independently established extents below and above it, with positive tree height. Require conk−below≥0 and conk+above≤treeHeight. Return the lower bound, upper bound and below+above column length in meters; no unseen decay extent is inferred.
lower=conkHeight−below; upper=conkHeight+above; length=below+above Use the exact units, boundary rules, ordering and missing-evidence conventions above.
| Output field | Meaning | Value type |
|---|---|---|
| assessedRotColumnLowerM | Assessed Rot Column Lower M; follow the units, sign, ordering and evidence convention stated above | list of number |
| assessedRotColumnUpperM | Assessed Rot Column Upper M; follow the units, sign, ordering and evidence convention stated above | list of number |
| assessedRotColumnLengthsM | Assessed Rot Column Lengths M; follow the units, sign, ordering and evidence convention stated above | list of number |

}Limitations and assumptions
A visible conk alone does not supply the internal decay boundaries needed for a length estimate. Interpretation depends on the units, sampling scope and exact model described above.
All listed fields require explicit values. Unexpected fields, incorrect types, nonfinite numbers and sparse evidence arrays fail validation; the specific bounds and alignment requirements are stated above. Extremely large inputs or outputs can also be rejected. An input error is distinct from a successful result reporting false, no matches or missing evidence.

Use Dutch Elm Disease Sanitation Pressure Checker when its separate inputs and assumptions fit the question: A sanitation record can compare infected material with material independently recorded as removed.
