Plants of Palisades State Park and Devils Gulch near Garretson South Dakota
Palisades State Park and Devil’s Gulch Park are both situated in Sioux Quartzite rock outcrops. These outcrops offer unique habitats for plants. Some of the plants on this list are only found on Sioux Quartzite.
The list of plants was generated from two sources. One being herbarium collections of plants and the other being observations of plants. Only plants identified to species or lower are included.
The first source is the Great Plains Region Herbarium Network accessed at NGPHerbaria.org. It is a data portal that allows queries of herbaria. Herbaria contain mostly pressed and dried vouchers of plants. The query for the data is State equal “South Dakota”, county equal “Minnehaha” and locality equal “Garretson”. This gets any collection recorded with a locality of Garretson which is the town near both sites.
The second source is Inaturalist accessed at inaturalist.org. Inaturalist is a database containing observations of plants and other biological organisms. The data was accessed using a circular boundary that encompassed both sites. Only “research grade” records are included. To be a research grade plant observation at species level or lower the following criteria must be met.
- It has a date
- It is georeferenced
- It has photos
- It isn’t of a captive or cultivated organism
- More than 2/3 of identifiers are in agreement of the species identification
