While much of the strength and endurance you gain from road running transfers to the trails, there is a more specific skillset required by rocky and rutted terrain. Steep climbs, sharp turns and greater topographic variety tend to make trail running more technical, often necessitating greater muscular strength. An increased sense of where your foot is in space, known as proprioception, is also important on uneven trails with unsure footing. What's more, trail races are synonymous with ultra events, so building up the proper endurance to handle increased mileage is essential.
