BIWFC SPONSORS PZP CONFERENCE  HOSTED BY SCIENCE CONSERVATION CENTER

The PZP Immunocontraception Conference, which was sponsored by BIWFC and hosted by the Science and Conservation Center (SCC) in Billings, Montana, drew representatives from various government agencies, NGO’s, tribal communities, sanctuaries, and universities as well as international delegates who work at controlling wildlife populations with PZP Immunocontraception. They discussed successes, failures, and struggles encountered in their PZP fertility control projects. In addition, researchers, who are advancing PZP technology, discussed and updated the attendees on current and ongoing research, and shared what the future of fertility control may hold.

While participating in the inaugural PZP Immunocontraception Conference, BIWFC Science & Policy Director Stephanie Boyles Griffin offered the following report on the efforts to advance the use of more effective, humane, sustainable, nonlethal methods for addressing conflicts and promoting coexistence with wildlife.

The three-day PZP Immunocontraception Conference was organized by the Montana-based Science and Conservation Center (SCC), and sponsored by the Botstiber Institute for Wildlife Fertility Control and Zoo Montana. More than 100 representatives and delegates from government agencies like the Bureau of Land Management (BLM) and the U.S. Forest Service, non-governmental organizations, tribal communities, sanctuaries and universities were in attendance.

The majority of the participants currently use the immunocontraception vaccine Porcine Zona Pellucida (PZP) as a humane, non-lethal and sustainable way to manage wildlife populations at sites and locations around the world.

The development of PZP as a wildlife management tool was born out of a growing shift in the way we interact with the natural world. Urbanization, development and human population growth have caused real or perceived conflicts between humans and wildlife to grow exponentially throughout the world, and as a result, each year, millions of wild animals are killed. Traditional approaches attempting to address such conflicts have focused primarily on institutionalized, cruel and lethal management methods, including the use of firearms, archery, body-gripping traps, snares, toxicants, spears and drowning.

The Humane Society of the United States (HSUS), and its affiliates, believe that fertility control offers a humane, non-lethal alternative to the lethal management of wildlife, and since the late 1980s, has been working with the SCC, researchers, federal, state and local agencies, and other NGOs to develop the PZP vaccine into a safe, effective and practical tool for the humane management of wildlife populations globally. These wildlife fertility control practitioners are currently working on improving field techniques, demonstrating the effectiveness of immunocontraception in the field, refining the vaccine manufacturing process and developing training standards. To that end, the conference featured presentations from HSUS and HSI staff members and partners about ongoing research to advance the use of PZP as a humane and sustainable wildlife management tool.

Audrey Delsink, Wildlife Director of HSI-Africa, presented on HSI’s contributions to the management of the African elephant populations with PZP in South Africa, focusing on the benchmark program in the Greater Makalali Private Game Reserve (GMPGR).  JJ van Altena, HSI-Africa’s Immunocontraception Implementation Specialist, discussed various field methodologies for using PZP to manage elephants in South Africa. Kali Pereira, Senior Wildlife Field Manager in the HSUS’s Wildlife Protection Department, shared field perspectives on the challenges associated with administering PZP and PZP-22 to white-tailed deer in urban and suburban landscapes in the U.S.

Grace Kahler, Wildlife Field Manager in the HSUS’s Wildlife Protection Department, shared highlights of the Platero Project, a four-year pilot project being conducted by the HSUS in partnership with the BLM to study the feasibility and logistics of applying PZP to a herd of wild burros in northwestern Arizona. Dr. Harm HogenEsch, a Professor and Associate Dean in the College of Veterinary Medicine at Purdue University, and a valuable partner in our efforts, presented on the Next Generation PZP Project—a study designed to develop a longer-acting, replicable and cost-efficient PZP vaccine formulation.

The SCC, a pioneering force in this important work for more than a quarter century, did an extraordinary job of organizing the conference. The momentum building toward expanded acceptance and use of PZP has been palpable at this event, and I’m excited to think about the possibilities for enhancing human-wildlife coexistence in the future as a result.  ____________________________________________________— Stephanie Boyles Griffin
