WPW - forest on the Salamanca map

[RichWhite]

Hi -- I recently purchased Wellington's Peninsular War and am enjoying it immensely. However, I was surprised to see on the Salamanca map the presence of large forested areas north and west of Calvarrasa de Ariba. In other maps & games in which this battlefield is depicted, these areas (around the British deployment) are generally depicted as a plain, or perhaps "rough" or "difficult" at most—with the forested areas being limited to the area of the French deployment.

I'm sure this wasn't an arbitrary choice and was based on careful research. If the designer is lurking, would it be possible to hear more about this, or perhaps see the sources for the contemporary state of the battlefield?

Thank you!
