impala

Identification evidence

Record visible diagnostic features, obscured features and plausible alternative identifications.

1. Which heel, rump, tail and horn features are actually visible in this observation? measurement
2. Which locally plausible antelope alternatives remain, and what additional view would distinguish them? boundary

Identity continuity

Retain the authority behind the taxonomic assignment and the evidence connecting sightings.

1. Which taxonomic authority supports the recorded impala assignment, and is a more specific form unresolved? provenance
2. What tag, collar, scar or combination of stable features supports matching this animal to a previous sighting? provenance

Developmental assignment

Record a defensible life-stage assessment without using horn absence as a complete sex test.

1. What anatomy, relative size and horn development support the recorded sex and life stage? measurement
2. Could immaturity, horn damage or an obscured view explain the apparent absence of horns? boundary

Reproductive and care context

Separate suspected reproductive status from confirmed evidence and document maternal associations.

1. What directly observed or professionally confirmed evidence supports rut activity, pregnancy, lactation or nursing? provenance
2. Would a proposed intervention separate a nursing pair or disturb a potentially dependent young animal? action

Nutritional trajectory

Track condition and feeding over time while preserving observation method and seasonal context.

1. How has body condition changed under the same assessment method, accounting for life stage and reproductive state? measurement
2. Is the animal grazing, browsing or ruminating, and was the observation long enough to interpret a lack of feeding? measurement

Functional impairment

Record gait, weight bearing, wounds and ability to remain with companions.

1. Can the impala rise, bear weight, walk and keep pace during naturally occurring movement? measurement
2. Which observed injuries or persistent impairments meet a qualified wildlife responder's escalation criteria? action

Social behaviour interpretation

Distinguish observed association and behaviour from assumptions about dominance, abandonment or illness.

1. Is the animal alone or associated with females and young, males, or a mixed group, and for how long? measurement
2. What evidence distinguishes breeding-related pursuit or territorial behaviour from disturbance or unexplained agitation? boundary

Usable habitat access

Distinguish nearby resources from resources the animal can safely reach and use.

1. Which forage patches, water points and cover areas has this animal actually used during the observation period? measurement
2. Do fences, roads, people or other immediate pressures obstruct its observed movement routes? boundary

Disturbance-sensitive observation

Record observer proximity and changes in vigilance, feeding or movement.

1. Did the impala stop feeding, increase vigilance or move away after the observer or vehicle approached? measurement
2. Should observation distance increase or observation stop to avoid continued displacement? action

Intervention readiness

Record the animal-specific reasons and prerequisites for capture, marking, treatment or relocation.

1. What observed need, applicable authorization and qualified specialist plan justify the proposed action for this impala? action
2. How will follow-up assess feeding, mobility, condition and reunion with any dependent young or established companions? action
