Eriosyce laui
Overview
Rimacactus is a genus of cacti with the sole species Rimacactus laui. It is native to Northern Chile, and at one point was considered a part of Eriosyce.
Eriosyce laui faces severe threats from mining activities and urban expansion in its extremely limited range in northern Chile's Atacama Desert. The species' tiny population is highly vulnerable to habitat destruction from copper mining operations, which directly remove or degrade the specialized rocky substrates this cactus requires. Collection pressure from cactus enthusiasts further threatens the remaining individuals, while climate change may alter the delicate moisture balance this desert specialist depends upon.
Habitat
Eriosyce laui inhabits rocky slopes and crevices in the hyperarid Atacama Desert of northern Chile, growing in mineral-rich soils between granite and volcanic rock formations. This specialized cactus requires the specific microclimate conditions found in these rocky desert environments, where it receives minimal but critical moisture from coastal fog.
