Azadirachta indica

Neem determination

Record supporting characters, contradictory observations and missing material before accepting the identification.

1. Does a complete mature leaf support A. indica rather than Melia azedarach or A. excelsa? definition
2. Which missing or conflicting characters require reproductive material, a voucher or specialist determination? boundary

Traceable neem origin

Keep source locality, mother-tree identity and nursery claims distinguishable from independently verified facts.

1. Which collection, accession or nursery record connects this plant to its source? provenance
2. Is a claimed cultivar or selected seed source documented, and which traits were actually verified? provenance

Site fit evidence

Record drainage, water supply, light and cold exposure with local evidence for acceptable conditions.

1. What drainage, soil-moisture, light and minimum-temperature observations describe this neem's actual rooting site? measurement
2. What evidence supports planting or retaining a neem of this developmental stage under those conditions? action

Neem decline assessment

Use repeated observations to distinguish locally expected leaf change from persistent damage requiring investigation.

1. How have leaf cover, shoot growth and branch dieback changed relative to this tree's previous seasonal observations? measurement
2. What evidence distinguishes water stress, cold injury, pest damage and other explanations before treatment is selected? action

Local reproductive performance

Relate flowering and fruit set to nearby neem trees, flower visitors and concurrent conditions without assuming causation.

1. When did this tree flower, set fruit and produce mature fruit, and how was each stage recognised? measurement
2. Where fruit set is low, what observations support investigation of pollination, maturity or environmental stress? boundary

Propagation readiness

Determine whether a particular lot remains suitable for the intended propagation method.

1. What collection date, maturity assessment, processing and storage conditions are recorded for this neem material? provenance
2. What germination or rooting test supports using, retesting or rejecting this lot? action

Harvest response

Record the organ removed, amount, timing and subsequent crown or reproductive response.

1. Is this neem managed primarily for shade, seed, foliage or another documented purpose, and what competing harvest demands exist? definition
2. What removal intensity and follow-up observations justify repeating, reducing or stopping harvest? action

Sample-specific composition

Attach analytical results to the sampled organ and lot; require a separate assessment for any resulting product or proposed use.

1. Which tree, organ, maturity stage and handling history does an azadirachtin measurement represent? provenance
2. Which proposed efficacy or safety conclusions exceed the tissue measurements and must be assessed in a product or treatment model? boundary

Unmanaged neem recruitment

Distinguish identified recruits from look-alikes and observed spread from assumed parentage.

1. Where are confirmed or suspected neem recruits appearing relative to planted trees and maintained boundaries? measurement
2. What evidence distinguishes seed-derived recruits, vegetative shoots and unrelated seedlings? definition

Plant, retain or remove

Make local planting and removal decisions reviewable without assigning a universal invasive or protected status to neem.

1. Which current local authority records establish any planting restrictions, protection or required controls for neem at this site? provenance
2. Given observed recruitment and the site's objectives, should the agent recommend planting, monitoring, fruit collection or removal, and what evidence supports that choice? action
