Range-wide status assessment of cirsium Range-wide status assessment of cirsium longistylum (long-styled thistle) EF41DE80-3A08-45F8-8F46-4E227778B454 Year: 2004 Figure 5. Cirsium longistylum habitat in the Dry Range. Figure 6. Cirsium longistylum habitat and flowering plants near Spur Park after fire. Known occurrences of C longistylum are predominantly on calcareous soils derived from dolomites, limestones or shales. Though intrusions of coarse-grained metamorphics are common in the Belts and the Castle Mountains, soils derived from these parent materials typically do not harbor populations of long-styled thistle. Unfortunately, good site-specific soil data are not available for most of the known populations. F. Land Ownership Most occurrences are on National Forest lands managed by the Helena and Lewis and Clark National Forests. Ten populations occur partially or entirely on private lands with the occurrences in the 14
