I've no experience of mountain biking in forests, but I'd assume the roads are far more likely to harbour glass and flints to puncture tyres - whereas in the forest, assuming your tyres aren't so low pressure that you get pinch punctures from the rim, the surface is fairly benign - leaves don't tend to puncture tyres....
Get some spare tubes, and carry one with you when you go any distance. Do a quick roadside swap if you need to, and fix the old one if you want to, later.
To reduce the risk, keep road bike tyres pumped up nice and hard, and avoid riding in the gutter where nasty stabby stuff tends to get swept. If you're used to looking ahead for tree roots and the like, transfer that skill to watching ahead for the glint of glass, or patches of gravel formed from potholes.
And NEVER, NEVER talk about how you don't get punctures. The fairy listens.
