Bufonia ramonensis grows only in the Negev Highlands on a single site, two km southwest of Mount Romem and about 2 km east of Lots cisterns.

Rock crevices and soil pockets between limestone expanses on moderate northern gentle slopes, at an altitude of 975 meters (900 meters in the published paper) in the Negev Highlands. B. ramonensis grows in the Artemisia siberi and Moricandia nitens plant community.

• Bufonia ramonensis is found only in a single site, and the number of plants in the population has been estimated at between 200 and 300. Although no rare plant species survey was conducted in the Negev Highlands, the mountains of the region were intensively sampled for decades by leading botanists. Consequently, the chances of finding another population is very small, but exists.
• Most plants grow in rock crevices and in soil pockets on the slopes, so they are not at risk, but the site is located near a main highway, and there is a lot of military activity and hiking in the area.
• All the plants are in a single section extending over about 1 acre, which endangers the plants, whether by random extinction, grazing or human activity.

The Bufonia ramonensis population is located in the Negev Highlands Reserve, 2 km east of the Lots cisterns, very close to the main road. The area should be marked and signposted. Action should be taken to prevent overgrazing, all-terrain vehicles or mechanical operations. A detailed survey of the area should be conducted to try to locate more populations. The existing population should be monitored.

Endemic to Israel.

Bufonia ramonensis is a dwarf shrub, endemic to a single site in the Negev Highlands in the Ramon Reserve, east of the Lots water cisterns. Although the species is within a nature reserve, it has been given the highest red number (5.3) and declared, according to the IUCN criteria, a species in "grave danger". The reason for this is that not only is it endemic, but also a rare species whose population is small (200-300 plants) and isolated and whose eradication from Israel implies its global extinction.
