The Cook-Albert Fuller Nature Center opened in 2015.[5] The 7,400-square foot facility is
LEED certified,[6] and includes displays about the preserve's
karst topography, wildflowers, plants, animals and the history of the site's founding.
The sanctuary includes a small amount of the raw humus
rendzina soil type, which is globally uncommon.[7] and is also found in the Marshall's Point State Natural Area, a residential development not open to the public.[8]
Orchid project
Although the sanctuary is home to wild orchids, it also operates an orchid
restoration project to cultivate and introduce rare orchids into otherwise natural plant communities.[9] 25 native orchid species are currently kept at the Ridges.[10] A 1998 survey of wild, native orchids was carried out in response to continued theft of the sanctuary orchids. 28 species were identified.[11]
