Nature Lore
Though the experiences of a ranger living in an arctic wasteland may differ dramatically from one who makes his home in a jungle, both have spent many years observing the patterns of nature, and both have arrived at similar conclusions about the relationship between living things and their environment.
All rangers, then, have an inherent understanding of natural lore, encompassing a broad set of principles involving conservation, ecology, and natural order. Though not every ranger knows specific details about particular situations, all of them understand the general concepts at work.
Some examples:- The plant and animal life in any given habitat tend to be interdependent. The butterfly pollinates the flower, the flower produces nectar to feed the butterfly.
- Animals and plants adapt to natural changes in the environment. Grass becomes dormant in the winter and grows again in the spring. A wolf's fur thickens as the temperature drops, and thins when the weather becomes warmer.
- To avoid ruining the land, natural resources used by man must be replenished. If trees are harvested in a forest, new trees should be planted in their place.
Nature Lore
| Ranger Level | Quality of Information |
|---|---|
| 1-3 | Knows general principles of how climate, terrain, and life forms interact. Can identify problems, but can only guess at causes. (The topsoil has eroded away.) |
| 4-6 | Can determine causes of problems. (Heavy rainfall washed away the topsoil and leached away the nutrients.) |
| 7+ | Can suggest solutions to problems. (Add fertilizer to the remaining soil. To prevent further erosion, keep land covered with grasses or trees.) |
A ranger's knowledge of natural lore enhances his reverence for all living things. In practical terms, it allows him to recognize ecological and environmental problems, both actual and potential. In some cases, he may be able to offer suggestions for correcting them.
There are no hard and fast rules for determining the extent of a ranger's natural lore and its application. The DM must decide how much a particular ranger knows on a case by case basis, taking into account the ranger's training, background, and primary terrain. In most situations, experience is the main factor; the higher the ranger's level, the more he's likely to know.
The Nature Lore table provides natural lore guidelines for rangers of various levels. The information is cumulative; a 7th-level ranger also knows the information available to lower-level rangers. Keep in mind that these are generalizations; a 2nd-level ranger who was raised on a farm may know as much about the ecology of growing crops as another ranger of 10th level. By way of illustration, the parenthetical comments indicate what the ranger might know if attempting to figure out why crops no longer grow in a once-fertile farmland.
If the DM is stumped as to whether a ranger knows a particular piece of information, he may require the ranger to make a Wisdom check, adding bonuses or penalties to the roll depending on the relative difficulty of the question. For instance, knowing if a particular substance will work as a fertilizer is a relatively easy question, requiring no penalty to the roll. Knowing which specific crops the fertilizer will nourish is a more difficult question, and a penalty to the roll may be in order. In all cases, the DM should use common sense. A ranger who's never been out of the desert won't know much about the effects of a hurricane on a coastal environment, regardless of his level.
