Opportunity Information: Apply for G25AS00333

The U.S. Geological Survey's Southwest Biological Science Center (SBSC) is offering financial assistance for research focused on the vulnerability and resilience of saguaro cacti in Saguaro National Park. Long-term drought and rising temperatures in the Southwest U.S. are threatening ecosystems, including the iconic saguaro, a keystone species supporting over 100 other species. Although saguaro populations began to recover in the 1960s, recent decades have seen a dramatic drop in seedling survival and recruitment—now less than 10% of what it was before 1995.

This grant supports studies that can help understand the causes behind these declines and identify strategies to protect saguaros amid increasing aridification. Findings could have broader applications to other public lands where saguaros and similar cacti grow. This opportunity is available only to organizations that are partners of the Desert Southwest Cooperative Ecosystem Studies Unit (CESU), and funding is contingent on availability.

  • The Geological Survey in the science and technology and other research and development sector is offering a public funding opportunity titled "Cooperative Agreement for affiliated Partner with the Desert Southwest Cooperative Ecosystem Studies Unit (CESU)" and is now available to receive applicants.
  • Interested and eligible applicants and submit their applications by referencing the CFDA number(s): 15.808.
  • This funding opportunity was created on 2025-07-29.
  • Applicants must submit their applications by 2025-08-29. (Agency may still review applications by suitable applicants for the remaining/unused allocated funding in 2025.)
  • Each selected applicant is eligible to receive up to $150,000.00 in funding.
  • Eligible applicants include: Others.
