Hypothesis
The extraction events of Anadenanthera colubrina are dependent on its density and the distance of these areas from the community.
Conclusion
The study found that the distance to resource areas influences the selection of sites for bark extraction, with nearby zones being preferred.
Supporting Evidence
- The study found that 52.1% of sampled Angicos in the ground area showed extraction signs.
- Extraction events were higher in the ground collection zone compared to the base of slope.
- Interviews indicated that the ground area was cited 42 times, while the base of slope was cited only once.
Takeaway
People collect bark from a plant called Angico, and they prefer to go to places that are closer to save time and energy.
Methodology
The study involved semi-structured interviews and sampling of Angico individuals to analyze extraction patterns.
Potential Biases
Potential biases may arise from the reliance on self-reported data from community members.
Limitations
The study was limited to a specific community and may not represent broader patterns of medicinal plant extraction.
Participant Demographics
The study included 36 men and 65 women aged 18 years or older from the Carão community.
