Abstract

Extractivism of forest products is an old practice that significantly contributes to the generation of income and subsistence of several traditional peoples and communities around the world. When practiced in an unsustainable manner, this action can compromise the population viability of the extracted species, leading to a decrease in plant populations and, in some cases, cause local extinction. In this chapter, we discuss the main methods and techniques used in research that seek to evaluate the ecological consequences of the extraction of forest products. We present the advantages and limitations of each method and the approaches for analyzing the data collected. Ultimately, it is the researcher’s decision to choose the most appropriate method for their research questions.

Notes

  1. 1.

    The analysis of the “J-inverted” based on visual models exhibits limitations in the elaboration of conclusions related to the sustainability of the extraction, since other population parameters such as growth rate and mortality rate are not included in these analyses.

  2. 2.

    Defined as the persistence of the individual at the same stage during its life history [32].

  3. 3.

    It is the time interval defined between two demographic samplings.

  4. 4.

    These are perturbation analyses that quantify the contribution of each element of the transition matrix to the composition of the population growth rate (λ). Sensitivity measures the absolute contribution, while elasticity is a relative measure of that contribution.
