Cost Analysis of Collection and Ex Situ Conservation of Seeds of Important Native Tree Species of Mexico

Abstract

In Mexico, there are barely any studies that estimate the cost of germplasm conservation especially that carried out ex situ. The objective of this study was to analyze the collection and storage costs (CSC) of seeds of some native tree species that have social and economic importance in Mexico. Information on the importance of native trees was obtained through a literature review and research from a seed bank and forest technical service providers. Based on the environmental and social importance, as well as the conservation status of native species, poverty attention, and food security, an indicator of economic and social importance has been designed using multicriteria analysis. The highest value of the indicator included 32 species; Fabaceae was the most represented family (28%). The CSC analysis was applied to the species with the highest value indicator, currently available market price (CMP), and stored in the seed bank (SB). They were evaluated using the “cost of collection” method comparing CMP vs. SB. The cost of accession in the SB is 11 times higher than the CMP with 7% of nominal interest rate (NIR) and increases 24 times during a storage period of ten years with the same NIR per year. Despite the costs associated with the maintenance and management of SBs, their importance for conservation and contribution to society is highlighted.
