The study showed that there is a lot of genetic diversity in the Arana Gulch population, and that the plants are not all clones of each other. This genetic diversity is important for the long-term survival of the species, as it increases the chances that some individuals will be better adapted to changing environmental conditions.

In summary, the Santa Cruz tarplant is an endangered plant endemic to Northern California, specifically in Santa Cruz and Monterey Counties. It is a small annual wildflower that grows in coastal prairie ecosystems with sandy clay soils. The plant is easily mistaken for other similar-looking species, but can be identified by its distinctive glands. It has a strong, citrusy aroma that repels potential feeders. The plant produces a large number of yellow daisy-like flowers and has a long tap root that allows it to thrive in drought conditions. Due to habitat loss and competition with non-native species, the Santa Cruz tarplant was almost extinct in the 1960s. It is now listed as an endangered species and efforts are being made to protect and restore its populations. Active management techniques, such as controlled burning, grazing, and scraping, have been used to restore populations in various locations. However, the success of these efforts has been limited and the plant population continues to
