Zamia restrepoi is a species of cycad in the family Zamiaceae.

As of 2020, according to a preliminary field investigations the sole remaining known subpopulation is alarmingly small, comprising fewer than 100 adult specimens. There is a potential for the existence of additional subpopulations, but extensive field surveys have been unsuccessful in locating them, necessitating further research to comprehensively understand the species' population distribution and abundance.[3]

Classification history

[edit]

The Type for Z. restrepoi was first collected in 1918 by Francis W. Pennell in northern Colombia. The type was not reported again until re-located by Rogrigo Bernal in 1986. Dennis Stevenson described the genus and two species, C. restrepoi and C. bernalii, in 1990. It was recognized that Chigua was very closely related to Zamia and might indeed be nested in Zamia.[4] In 2009, Anders Lindström reclassified C. restrepoi as Z. restrepoi and C. bernalii as a synonym of Z. restrepoi.[5][6]

Threats

[edit]

The species underwent a drastic population decline due to the flooding and construction of the "Urra" Dam in 2000, with only around 30 individuals saved. In 2012, a small subpopulation of less than 100 adults was found in two tiny forest patches nearby. These patches are at risk from deforestation caused by agricultural and urban expansion, especially for cattle ranching and crops, making the species' survival uncertain.[3]
