In various embodiments, panel forms can be used to control erosion or retain dirt walls. Each panel form can be comprised of a substantially rigid body that is adapted to be mounted to the ground and can include connectors configured to receive mounts which mount the panel form to the ground. A plurality of panel forms can be used to form a fence, or a retaining wall, where the connectors extending from each panel form can be configured to mate and connect the panel forms together. In various embodiments, the mounts can be inserted through apertures in the mating connectors to provide a pivot about which the adjacent panel forms may be hingedly connected. In various embodiments, each panel form may include a tab extending therefrom which is configured to be received in a corresponding slot in the adjacent panel to reduce, or even eliminate, gaps between adjacent panel forms.
