Coyote cloudwing1/6/2023 ![]() ![]() Increasing drought and changing temperatures drive researchers to seek more efficient and effective means to aid management of coniferous forests across the western United States. As a management guideline, it is a reasonable assumption that the variety among plant communities and structures increases the potential for maintaining diverse kinds of animal habitats and resultant populations. A mixture of forest attributes maintained in time and space fundamentally supports a certain level of diversity as indicated by a richness value. ![]() Common sense dictates that plants and animals exist in a biotic community because that community has sufficient resources to sustain life. The SR process broadly categorizes the number of plant and animal life forms to arrive at a composite species richness value. This report provides an example of how inventory information can characterize the complexity of biological diversity in the ponderosa pine forest type in Arizona. However, SR data can include life his-tory information from published literature to enhance the SR value. Without abundance data, a common quantitative index for species diversity cannot be determined. Without a list of species, resource management decisions may have negative or unknown effects on all species occupying a forest type. A richness list derived from existing inventories enhances a manager's understanding of the complexity of the plant and animal communities they manage. Species richness (SR) is a tool that managers can use to include diversity in planning and decision-making and is a convenient and useful way to characterize the first level of biological diversity. ![]()
