Not only is the ranger able to track the movement of others, he's also adept at concealing his own trail. If a ranger moves at half his normal movement rate, he may cover his footprints, avoid snapping twigs, and execute similar actions necessary to conceal his trail. When other characters, rangers included, attempt to track a ranger who has concealed his trail, they do so at a -5 penalty to their Tracking scores. (If a terrain- specialized ranger concealed his trail while moving through his primary terrain, others suffer a -7 penalty to their Tracking scores.)
By flattening his body or crouching in such as way as to blend into dark areas, and remaining perfectly still while doing so, the ranger can render himself nearly invisible in natural surroundings. This ability to hide in shadows works equally well in ields of tall grass, clumps of bushes, rocky hills, or any other wilderness area with dark or shaded terrain.
When hiding, the ranger can conceal himself from attackers and eavesdrop on his enemies. He can hide near a well-traveled road and secretly observe passersby, or conceal himself near an enemy campsite, waiting for an opportune moment to steal their treasure or supplies.
Table 8 in Chapter 1 gives the base chance for a ranger to hide in shadows, subject to the modifiers for race, Dexterity and armor (Tables 9-11). The following restrictions also apply:

non-wilderness setting, the ranger's chance is halved. Apply this reduction after
