Part III, Line 1a:In accordance with industry practice, the Houston Zoo does not capitalize animal and horticultural collections; acquisitions are reported as expenditures in the period of acquisition. The Houston Zoo is responsible for the health and welfare of its animal and horticultural collections. The Houston Zoo maintains records of its collections and any exchanges with other organizations. Under the direction of the Board of Directors, the President, and the curatorial staff, collections continue to be cared for, exhibited, and expanded. In 2024 and 2023, the Houston Zoo expended approximately $16,000 and $45,000, respectively, to expand its collections. In an ongoing commitment to enhance worldwide reproduction and conservation of animals, the Houston Zoo exchanges animals with zoos and aquariums accredited by the AZA. Consistent with industry practice, the Houston Zoo does not record any liability for such exchange arrangements as generally these arrangements are without monetary consideration.
Part III, Line 4:The Houston Zoo is a leading conservation and education organization dedicated to providing the animals in its collection with the highest quality of care. Many are vulnerable, threatened or endangered in the wild. The Zoo's animals serve as "ambassadors," helping to inform guests and inspire action to save their wild counterparts.
Part V, Line 4:The purpose of the endowment fund is to provide ongoing support for operating and capital needs and program services that are consistent with the Houston Zoo's mission and vision.

Part I, Line 2:The Houston Zoo's selection standards for awarding grants are based on our mission statement goals and long-term development of regional programs. We do not solicit proposals, nor do we have a formal process for receiving and evaluating grant requests. Instead, we actively seek out projects that fit the guidelines of the Zoo's Wildlife Conservation Program (see Part III, Line 4b). We then meet with researchers and potential partners to determine how well their aspirations fit with Zoo guidelines. We make only minimal investments with new partners until we are satisfied that the researchers will communicate and interact with the Zoo (web, media, reports, speaker requests, articles, etc.), that their research program is sustainable over time, and holds promise for desired results. We monitor progress and outcomes through periodic site visits where practicable and receipt of regular reports on activities and results.

Instead, we actively seek out projects that fit the guidelines of the Zoo's wildlife conservation goals and objectives. We then meet with potential conservation partners to see how well they fit with those guidelines. We make only minimal investments with new partners until we are satisfied that they will communicate and interact with the Zoo (web, media, reports, speaker requests, articles, etc.). We also closely monitor each partner's research program to ensure its long-term sustainability. We monitor progress and outcomes through periodic site visits where practicable and regular written reports on activities and results.ExplanationTxt
