Despite growing importance of wild pigs (Sus scrofa) as an invasive species, techniques to obtain estimates of demographic characteristics (e.g. population density, juvenile survival rates) are lacking. Information about these rates is critical to effective management of wild pig populations and assessment of risks to ecosystem health, necessitating development of techniques to measure these basic rates. In this thesis, I develop methods to facilitate genetic capture-mark-recapture of this and other social ungulate species (Chapter 2), compare a suite of common field and analytical techniques to estimate animal population density and evaluate their robustness to effects of common ecological and observational processes (Chapter 3), and pilot use of vaginal implant transmitters in wild pigs and evaluate techniques to monitor survival of juvenile wild pigs (Chapter 4). This work will aid in management of this invasive species and assessment of threats posed by wild pig populations to natural and anthropogenic ecosystems.
