We encourage you to visit the websites of the following organizations to learn about their work with wildlife worldwide.

The Humane Society of the United States

Together with millions of supporters, The Humane Society of the United States (HSUS) takes on puppy mills, factory farms, the fur trade, trophy hunting, animal cosmetics testing and other cruel industries. They rescue and care for thousands of animals every year through their Animal Rescue Team’s work and other hands-on animal care services. They fight all forms of animal cruelty to achieve the vision behind their name: A Humane Society.

Humane Society International

Humane Society International (HSI) works around the globe to promote the human-animal bond, rescue and protect dogs and cats, improve farm animal welfare, protect wildlife, promote animal-free testing and research, respond to natural disasters and confront cruelty to animals in all of its forms.

The UK Squirrel Accord

The UK Squirrel Accord (UKSA) is a UK-wide partnership of 37 leading conservation and forestry organizations, government agencies and companies, with links to voluntary red squirrel conservation groups. UKSA works collaboratively to preserve the UK’s wooded landscapes and associated biodiversity under the following aims:  to secure and expand UK red squirrel populations beyond current thresholds; and to ensure UK woodlands flourish and deliver multiple benefits for future generations of wildlife and people.  In addition, UKSA is currently conducting research into a non lethal fertility control method to control grey squirrel population densities and support eradication efforts in the UK.

Return to Freedom

Return to Freedom is dedicated to preserving the freedom, diversity, and habitat of America’s wild horses and burros through sanctuary, education, advocacy, and conservation, while enriching the human spirit through direct experience with the natural world.

Humane Horse  works to improve the care and handling of wild and domestic horses through research, education, and application of equine behavior and welfare science. Their goal is to demonstrate that low stress, science informed handling and gathering of wild horses is a key factor for sustainable management. They intend to work with advocates and government agencies, with a focus on horse welfare.

The Science and Conservation Center

One of the major efforts of the Science and Conservation Center at ZooMontana involves the humane control of wildlife populations by means of fertility control. To that end, the Science and Conservation Center serves as an independent non-profit organization that is the world’s only dedicated facility for the development of wildlife contraceptives and methods of application. This center produces and carries out quality control for a wildlife contraceptive vaccine, distributes the vaccine and is the repository for all records and data required by the Food and Drug Administration and Environmental Protection Agency.

The National Wildlife Research Center 

The National Wildlife Research Center (NWRC) is the research unit of the USDA-APHIS Wildlife Services program. Scientists and support staff are dedicated to finding solutions to challenging wildlife damage management problems related to agriculture, natural resources, property, and human health and safety.  Human-wildlife conflicts, wildlife damage, nuisance and pest animals, wildlife disease, invasive species, overabundant wildlife, and overall ecosystem health are just some of the topics studied by researchers at the National Wildlife Research Center.

Webinars Featuring Wildlife Fertility Control

UK Squirrel Accord presented this webinar on the use of fertility control to manage the grey squirrel population.


In this presentation explains how their non-profit organization promotes humane methods of deer population management and the ecological health of their parks and communities.
