Only your terrain have texture and for your trees - function call texture2D(baseTexture, gl_TexCoord[0].st) return black (0,0,0,1). Your trees have per-vertex color attribute, and your ground dont(?) (i dont know to what value it defaults). Simplest options to fix this - set 1x1 white texture to your trees or add color array to ground (with black color values) and use texture2D(baseTexture, gl_TexCoord[0].st) + gl_Color, or write different shaders (one version with texture, one without). If gl_Color defaults to black without color array, you can use vec4 color = texture2D(baseTexture, gl_TexCoord[0].st) + gl_Color; without any changes.
