Sandstone, according to the three group members, “is a hotspot for biodiversity on the Domain”. To quantify their findings, a 500 cm-squared circular lot was made at each of the twelve outcrops to monitor Diamorpha and Minuartia presence. In addition to recording their density, insect presence, moss and lichen, amount of direct sunlight, and types of substrait were recorded as indicators. These indicators were used to define a preferred growing condition for Diamorpha and Minuartia. By identifying responses from the endemic species, this research will be helpful in understanding the favorable conditions needed for supporting the biodiversity of these short-lived annuals.
The Cumberland Plateau is prized for its richness in biodiversity. Endemic plant species such as Miamorpha and Minuartia play even with their relatively short-life cycle a key part in this wide range of biodiversity and in supporting other habitats.
