|Scientific Name:||Zamia neurophyllidia D.W.Stev.|
|Red List Category & Criteria:||Vulnerable A2c; C1 ver 3.1|
|Reviewer(s):||Donaldson, J.S. & Bösenberg, J.D.|
Qualifies as Vulnerable based on decline of >30% over the past three generations due to habitat destruction as well as under criterion C1 based on a population size of 5,000 mature individuals and decline of >10% over three generations. If a hydroelectric project goes ahead, the decline may be >30%.
|Previously published Red List assessments:|
|Range Description:||Little is known of the true extent of the geographic distribution of this species, but the populations that have been surveyed to date occur on steep hills of primary tropical deciduous forest along the Río Changuinola and its tributaries.

|Population:||Little is known about population numbers|
|Current Population Trend:||Decreasing|
|Habitat and Ecology:||This species grows as an understorey plant on steep hills in primary tropical deciduous forest along rivers. The understorey in the areas of the forest with the largest trees (in what could be referred to as protected primary forest) is dominated by plants with trunks well in excess of one metre and often measuring 1.5–2 m tall.|
|Generation Length (years):||30|
|Major Threat(s):||A hydro-electric dam project that is being planned for the region may have significant negative impacts on several subpopulations.|
|Conservation Actions:||This species is listed on Appendix II of the CITES Appendices.|
