The Essex Naturalist
(Orsett Golf Course). Preliminary data on three of these sites is published in
Essex Field Club Newsletters (Harvey 1994a, 1994c, 1995b, 1995c) and a full
description of the Broom Hill locality is given in The Natural History of the
Thames Terraces at West Tilbury elsewhere in this volume. There is still much to
be done before the county can be considered to have been thoroughly
investigated for its bee fauna.
