The Ethnoecology presents itself as a branch of science enriched by a series of methodological tools that allow researchers to understand more fully a study environment. In this work was used a series of instruments in order to diagnose how the use of resources by human populations may affectplant and animal communities in a rural community in the municipality of Cabaceiras,Paraíba’s semiarid. This work initially found that the Appearance Ecological Hypothesis was confirmed in the rural community in which the survey was conducted.. Similarly, the use of vegetation recorded can be put into evidence by using the ratio of PCI (Priority Conservation Index), the UV (Use value) plant species and data obtained from the in situ inventory of items of plant origin, confirming that this usage may cause pressure on plant resources of the site. As a means of recording the direction of this pressure, the inventory served as director in situ, indicating how the extraction and replacement of items can act in this process. The same activity indicated greater impact, such as construction, with emphasis on timber harvesting for rural construction, especially regarding fences. To register this phenomenon more thoroughly, an inventory was made of a kind used in the construction of waxes, which indicated a high pressure on a few species, especially the pereiro (Aspidosperma pyrifolium Tul) and marmeleiro (Croton blanchetianus Bail). Regarding the use of wildlife, initially sought to check the local knowledge about the animals that live in the community and with which informants live somehow. It was recorded contact with a large number of species, which generated a deep knowledge about the biological characteristics and an accumulation of knowledge that can be rich in detail for some species. This knowledge reflected in the uses that were recorded for the species. Although not verify the use of all species that became known, there was a record of a considerable number of these (47.9%), with most uses present only in memory, without being over done these days . However, some uses / influences had a greater amount of current records, particularly the records of conflicts between wild animals and human allocations in the community, with designs and plantings. This fact indicates that the pressure being made on vegetation may be being added to the historic uses of the data fauna, causing a feedback process that displaces the niche of the latter, resulting in a greater number of conflicts. It is observed from these studies that the associated application of these tools allows for a rich characterization of ecological relationships that may be occurring in places where man was implanted.
