EOO: 4 km ². AOO: 4 km ². Evaluation of IUCN: Critically Endangered.

Eugenia inconspicua is endemic to Mexico and has a very restricted distribution in the city of Culiacan, in the state of Sinaloa. The estimated extent of occurrence (EOO) and area of occupancy (AOO) fall within the thresholds of Critically Endangered category under the criterion B. Eugenia inconspicua is known from only 2 records very close to each other in disturbed areas of the Dry Tropical Forest, from which is inferred only one location. The region has a high level of degradation, being unprotected and under enormous pressure from urban expansion ( CONABIO 2018). The threats that lead to continuing decline of habitat quality are urban expansion, forest fires and other human activities. The region has very few botanical studies and floristic inventories, but efforts are particularly important due to the physiographic and climatic variations and biological diversity in this region as it is estimated that it presents around 3,500 vascular plants ( Vega et al. 1989, Hernández & Vega 1989, Rzedowski 1991, Vega et al. 2000, Villaseñor & Ortiz 2014, Villaseñor 2016). The low number of records for E. inconspicua is an indicator that in the region need more efforts of collection and studies that can evaluate a more precise status of its population and habitat. Taking a precautionary approach, Eugenia insconspicua is here classified as Critically Endangered (CR) as it meets the criterion B2ab (iii).
