These are descripted magical spells/abilities that he is known to possess. There are additional spells that are not listed here. These can be found on dungeons and dragon webpages and similar sites. More fully described minus the mathematical terminologies that aren't used in free role-play. They are for the most part known ranger spells that one can come to the knowledge of through a local bard.
-Animals-
Rangers have an ability to communicate with animals, be it in surrounding areas or directly next to them in a city. One could say the rangers are able to understand what they are saying amongst the other animals as well. A means of this is persay the occasional squirrel coming into a rangers path amongst the trees, chittering and making those miniscule body movements was actually making body signals and the universal language of reading lips. Animals themselves after watching humanoids for centuries have adapted to their prescense and are familiar with their language. And if say, one was to look close enough, or not that close, but in that subliminal perspective, they could perhaps understand what was being communicated. Or maybe, the ranger has been in the trees far too long. And had been sipping far too much mead at the taverns. In the same, he can use this ability to send warnings throughout the area as well as use animals for numerous other purposes that a companion would be able to fulfill. In related issues. He also has the ability to tame wild animals into similar cooperation. Through the blessing of a god or nature itself, it is also said that one is able to increase the size or diminish that of an animal as well.

-Nature-
There are two ways a ranger is knoweledgeable and uses nature and it's habitation of plants and trees. One is through herbalism, where certain combination or single use of particular herbs and pieces of plants are able to be put to use for healing as well as poisoning purposes. There are also ways to control nature that are also at his disposal. The commanding of vines, both fresh and strong as well as old and dried up are at his command, able to be used to entangle targets, be used as ropes, barriers, etc etc. It may be that this is another way to go about passing through terrain without leaving a trace of track of footfall as nature can be summoned or constantly given to removing such at his passing. There is also the summoning of the trees themselves. The bark they possess either dried outer layers themselves for instance able to be put to use as secondary means of armor, protection or even a barrier or shield. It is said that rangers and druids are able to take up the shape and look like a tree themselves. This may be a means of doing so, calling upon particular means to form oneself into a tree with similar aid from nature in ways that can range from simple to magically complex. Boobytraps are also able to be produced from similar use of nature and the natural surroundings that provide numerous ways to entrap another. The jutting forth of spikes, say from the solid foundation of roots can be called upon. Some sharper than others, their ends as many as the bottoms of a tree will allow. If not the addition of stones secreted within the earth itself. All of this normally requires one to be able to speak to plants, in ways similar to how one speaks with an animal. Trees for instant are known to be some of the most ancient of beings. With particular herbs, and prayers to particular gods, plants can be aided in their growth as well as diminishment of size. Similar allowances will allow him to forsee the terrain and similar surroundings, both from the earthen ground to the heights of the trees if enough time is spent in the process. In the same, there are numerous techniques for moving within the trees. Perhaps one of them is the use and beckoning of the trees themselves to aid in such..in most insidious of ways.

-Weather-
Another element of nature and its' inhabitatnts is the weather itself. The winds for instance can be called upon to douse flames, to remove his scent from the breath of another, to cause the path of missle objects to become thwarted. To pull ones words to the ears of one at a distance even if just a whisper. To in the same conceal ones voice from being heard by another. Such control over the winds may also allow him the means of superficial flight and movement amongst trees or similar spannings of distance. It will also allow particular temperatures to be under his control.
