Forage Radius KM Range Estimate
Invert a measured trip/handling time budget to one-way reach with distinct outbound/return speeds; no universal foraging radius, energy reserve or landscape accessibility claim.
Description
A round-trip time budget separates outbound travel, handling and return travel.
A round-trip time budget separates outbound travel, handling and return travel. Different flight speeds change the reachable one-way distance even when the total budget is fixed.1
Invert a measured trip/handling time budget to one-way reach with distinct outbound/return speeds; no universal foraging radius, energy reserve or landscape accessibility claim.
When to use Forage Radius KM Range Estimate
Use this tool to invert a measured trip/handling time budget to one-way reach with distinct outbound/return speeds; no universal foraging radius, energy reserve or landscape accessibility claim.
Prepare the hive, sample or operating measurements and any supplied target values. Confirm units, timing and whether counts or masses refer to the same population or batch.
How to use Forage Radius KM Range Estimate and understand its results
- Prepare the hive, sample or operating measurements and any supplied target values. Confirm units, timing and whether counts or masses refer to the same population or batch.
- Enter totalTripBudgetMinutes, handlingMinutes, outboundSpeedMPerSecond, returnSpeedMPerSecond using the field table and calculation rules, then run the tool.
- Read modelOneWayForageRadiusKm, outboundFlightSeconds, returnFlightSeconds. 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 |
|---|---|---|---|
| totalTripBudgetMinutes | Total trip budget minutes | number | Required |
| handlingMinutes | Handling minutes | number | Required |
| outboundSpeedMPerSecond | Outbound speed m per second | number | Required |
| returnSpeedMPerSecond | Return speed m per second | number | Required |
Supply positive total trip minutes and positive outbound/return speeds in m/s, with nonnegative handling time no greater than the total. Return modeled one-way reach in km and the two travel times in seconds. Handling equal to total leaves zero travel distance.
distanceM = 60(totalMinutes−handlingMinutes)/(1/outboundSpeed+1/returnSpeed) Units, indexing, boundary conditions and exceptional cases are defined in the calculation rules above.
| Output field | Meaning | Value type |
|---|---|---|
| modelOneWayForageRadiusKm | Model one way forage radius km | number |
| outboundFlightSeconds | Outbound flight seconds | number |
| returnFlightSeconds | Return flight seconds | number |

}Limitations and assumptions
This is a time-budget scenario, not a universal foraging radius. Energy reserves, wind changes, landscape barriers and actual forage access are excluded.
Numeric inputs must be finite. Follow the calculation-specific rules for overflow, underflow and exceptional cases. Missing required fields, extra fields, wrong value types and violations of the calculation rules are input errors.
Alternative or Complementary methods
Use Site Forage Capacity Colonies: Screen seasonal colony capacity from supplied habitat nectar access and competing/ecological reserves; negative forage budget is retained and forage timing or pollination adequacy is not inferred. For a complementary task, use Feeder Jar Refill Frequency: Locate the first forecast feeder reserve crossing with piecewise-constant daily withdrawal; this is not a fixed refill schedule or feeding recommendation.
