DELEP has been involved in many collaborations since its inception in diverse fields ranging from ecological restoration, biomedical research, to genomics.
Land Management and Ecological Restoration
- In 1990-1991, DELEP grew and planted 200 plants of Acaciella angustissima at the Buenos Aires National Wildlife Refuge as part of a project with the U.S. Fish and Wildlife Service to see if the seeds produced by the plants might contribute to overwintering survival of the endangered masked bobwhite quail.
- The Arizona State Land Department contracted with DELEP from 1993-2001 to produce thousands of tree seedlings each year for conservation plantings around the state.
- In 1996, Sam Bamberg & Associates arranged for DELEP to grow 300 seedlings of Olneya tesota for a revegetation project at the Chemgold Inc. Picacho Mine in California.
- In 2017, DELEP hosted Dr. Fritz Heystek and Dr. Yoganambal Kistensamy from the Plant Protection Research Institute of the Agricultural Research Council in South Africa who were investigating mesquite twig girdlers as a biocontrol agent for invasive mesquite in South Africa.
DELEP personnel and Dr. Jack Stroehline established a mesquite planting at the UA's Page Ranch north of Tucson to evaluate mesquite growth using water catchments.
- In 1989-1990 DELEP provided plant material to researchers at Monsanto for commercial applications analysis.
- DELEP collaborated with Sankyo Co., Ltd. to provide plant material for biomedical screening from 1992-2003. The program was involved in a similar project from 1994-1996 with the UA Southwest Center for Natural Products Research and Commercialization that was sponsored through the Clayton Foundation.
- From 1990-1994, DELEP worked with International Floratech to grow over 1,000 seedlings of Psorothamnus spinosus and plant these on a farm near Wellton, in southwestern Arizona. The calyx glands of this species yield an aromatic resin that was being evaluating for use in cleaning products and cosmetics.
- In 1994, DELEP hosted Mr. Shoaib Ismail from the Biosaline Research Labs at the University of Karachi, Pakistan.
- Also in 1994, DELEP hosted Dr. Mohamed Thanaa Hassan from the Agriculture Research Station in Alexandria, Egypt.
- 1994 also saw DELEP hosted Dr. Shafik Ahmed El Gendy from the Aain Shams University, Cairo, Egypt to look at low water-use landscape plants.
- In 1997, DELEP hosted Fulbright Scholar Dr. Alejandra Vilela from the University of Buenos Aires, in Argentina, who conducted a project to evaluate simple, low-cost propagation techniques for Prosopis for use in rural tree planting programs and agroforestry.
- In 2002, DELEP hosted Dr. Joe Miller who was collecting samples for phylogenetic analysis leading to a taxonomic revision of the genus Acacia.
- In 2009, DELEP hosted Dr. Jorge Santiago-Blay who made collections of gum exudates from legumes in DELEP's fields.
- In 2013, DELEP personnel consulted on a project to grow Joshua trees (Yucca brevifolia) at the Northeast Forestry University in Harbin, China.
- In 2013, DELEP researcher Dr. Margaret Norem derived C-values for several legumes species using the laboratory of Dr. David Gailbraith at the UA Bio5 Institute.
- In 2017, DELEP grew plants of Abrus precatorius and provided leaf samples to researchers at the Los Alamos National Laboratory for genomic sequencing.
