If you have experience with or insight into any programme that employed some form of contraception as a means to control wild populations of macaques, I am keen to speak with you. We're in the process of organizing a working group and possible event that explores the relevant considerations, and the effectiveness and welfare implications of such programmes. We hope to provide perspetives from an array of locales and situations.
In the future we hope to look at other, related ideas, such as optimal contraceptive methods for use in rescue centres, how these tie in with potential release, etc.
Please do contact me if you are interested in talking about this! Thanks, and I look forward to meeting you :)
