1) funding opportunity number P22AS00073. 2) funding opportunity goals text the southwest border resource protection program (swbrpp) provides financial assistance to NPS units, as well as educational institutions, nonprofit organizations, tribes, and local and state agencies to improve resource stewardship, achieve international cooperation, provide meaningful interpretation and conduct scientific research, which will lead to increased appreciation and understanding of our shared natural and cultural heritage along our international border with mexico. This project will assess the population sizes of, habitat requirements of, and border related threats towards a cactus species that is listed as threatened in the united states under the endangered species act of 1973 and in mexico under secretaria DE medio ambiente y recursos naturales 2010 (NOM 059 semarnat 2010) bunched cory cactus (coryphantha ramillosa). The most well studied population of the bunched cory cactus occurs in a 4 KM2AREA in big bend national park (bibe), adjacent to the RIO grande. Very little is known about this species outside of this single population, however IT has been reported to occur across the river from the well known bibe population in mexico, on private land in eastern brewster county and in terrel county in texas, and further south in chihuahua and coahuila, mexico (USFWS 2018 inaturalist 2021). A major obstacle in obtaining more information about this species is access to the remote areas in its range. The project will support a binational team with expert knowledge of the land from bibe, comision nacional DE areas naturales protegidas (conanp) in mexico, and RIO bravo restoration (RBR) to conduct field work and statistical analyses on the current state of this species.
