Bit of terrain not rendering?

[SteveR]

Hi all, just a quick one, I have just started a project and for some reason there is a bit of my terrain not rendering. It shows OK in the preview but not in the render.

See the attached image to demonstrate what I mean. Any ideas what I am doing wrong and how to fix it? The terrain is driven primarily by a TIF image file.

Thanks
Steve
