U svom prirodnom staništu Sabal minor se postupno počeo širiti prema sjeveru. Prema autorima Erin A. Tripp, Kyle G. Dexter [Duke University, Durham NC, USA] članka
Sabal minor (Arecaceae): a new northern record of palms in eastern North America , Castanea. 71(2):172-177, 2006 Jun.

". . . We report a Sabal minor population found on 30 October 2004 while canoeing on Gardner Creek (Martin County), a tributary of the lower Roanoke River just southeast of the Bertie County border in North Carolina . . . the population is located on a partially inundated hummock in a bottomland bald cypress swamp, growing with Nyssa aquatica L., Acer rubrum L., Taxodium distichum (L.) L. Rich, and Quercus lyrata Walt. . . "
Sažetak:
"We report a new Sabal minor county record for North Carolina that represents the furthest known northern population of the largely tropical family Arecaceae in eastern North America. We give a brief introduction to Sabal and explain why this S. minor population may represent a northward range expansion in response to climate warming in northeast North Carolina. Finally, we discuss the usefulness of both historical herbarium specimens and modern day botanical collections to research on climate change and plant population responses"
Autori ekspanziju Sabal minora povezuju s klimatskim promjenama i smanjenjem broja ledenih dana na tom području
