As part of Arizona State University’s net-zero carbon initiative, 1000 mesquite trees were planted on a vacant plot of land at West Campus to sequester carbon from the atmosphere. Urban forestry is typically a method of carbon capture in temperate areas, but it is hypothesized that the same principle can be employed in arid regions as well. To test this hypothesis a carbon model was constructed using the pools and fluxes measured at the Carbon sink and learning forest at West Campus. As an ideal, another carbon model was constructed for the mature mesquite forest at the Hassayampa River Preserve to project how the carbon cycle at West Campus could change over time as the forest matures. The results indicate that the West Campus plot currently functions as a carbon source while the site at the Hassayampa river preserve currently functions as a carbon sink. Soil composition at both sites differ with inorganic carbon contributing to the largest percentage at West Campus, and organic carbon at Hassayampa. Predictive modeling using biomass accumulation estimates and photosynthesis rates for the Carbon Sink Forest at West Campus both predict approximately 290 metric tons of carbon sequestration after 30 years. Modeling net ecosystem exchange predicts that the West Campus plot will begin to act as a carbon sink after 33 years.
Today, some modern zoos, aquariums, and similar animal-exhibiting institutions continue to shift their priorities toward a focus on the conservation of wildlife. Conservation challenges span a broad subject area. The focus that any institution chooses can vary greatly in terms of magnitude and measures of significance. Many modern zoos often choose to make global conservation a central institutional priority: conservation of biodiversity, habitat protection, species extinction, and more. Some institutions, however, set conservation priorities on a smaller scale, focusing on contributions that have a more indirect effect on wild species and habitats, such as the welfare of populations in captivity, raising public awareness of conservation missions, and conservation education. By comparing the institutional priorities of two organizations within the Association of Zoos and Aquariums (AZA), the Arizona-Sonora Desert Museum and the Phoenix Zoo, I explore how each institution manages its living collections and works toward its respective conservation mission. I interviewed members of each institution and analyzed the similarities and differences between the organizations based on their management of living collections, and how different mission statements might shape their work. This included investigating the focus each institution has on animal welfare, in situ and ex situ conservation, and maintaining public interest. This also required defining what conservation and welfare mean to each institution and how that affects the management of their living collections. From a literature review and interviews with representatives from each institution, I was able to determine that despite any differences in style or in the language of respective mission statements, each institution prioritizes connecting the public and conservation of biodiversity. While they employ different approaches - one institution takes a regional interest in the Sonoran Desert ecosystem and landscape; the other takes a more global approach to its experiences, exhibits, and collections - the core values and ultimately the vision remain the same. Conservation may serve as the primary motivator for both the Museum and the Zoo, but my thesis is that this rationale could not be realized by itself for these institutions. Rather, conservation as a core value relies upon the support of other critical institutional priorities working together. In this way animal welfare, public engagement, and conservation relate to one another as institutional values and create the impact that the zoo and museum have on their local communities, as well as on conservation as a whole.
