Faint, high redshift galaxies constitute a background noise for TPF, which can cause various problems, such as galaxies mis-classified as planets, false detections due to confusion noise, and requiring greater uv-plane coverage for each individual interferometer. We discuss these issues, and their impact on the observation strategy. We utilize semi-analytical galaxy formation models to quantify the number of high-redshift galaxies in a "worst case" scenario: i.e. in a model in which the number of galaxies are maximized in a way that is consistent with other current observations.
