Forest dynamics itself is a broad topic. It may be important to find some relationships between disturbances and dynamics but if we run meta-analysis then how can it be possible to check some of the dynamic properties with different forms of disturbances in different forest covers? Is it logical to test single structural pattern of trees as a dynamic property from different papers of different forest types?
You have to adjust for bias of different methodologies in a meta analysis
Thank you Andrew Paul for your answer. Could you please give me some clues on it?
La dynamique de la végétation forestière peut être mesurer soit :
- Par certains indices d’ordres écologiques, tels que la richesse floristique, les types biologique, l’indice de rareté, la fréquence des espèces, l’indice de perturbation…
- Ou par les nouvelles technologies SIG et Télédétection exemple article suivant : Evolution spatio-temporelle des formations végétales du parc national de Belezma de la région Est de l’Algérie. Auteurs Smaihi(1) , Kalla(2). 2017. Revue : Courrier du Savoir Biskra.
Answer to the question : Best way to check disturbance effects on forest dynamics in some regions?
1) Identify the nature of disturbances for the medium to study. Example: drought, flood, fires, pathology ...;
2) spatially and temporally locate each type of disturbance by drawing maps. Example: geomatic approach;
3) Measure each type of disturbance by scientific methods. Example: fire risk modeling and comparison with the fire range map;
4) Study the consequences for each type of disturbance. Example: one of the consequences of the degradation of vegetation is erosion ...;
5) Seek solutions. The simplest are the most effective.

Thank you so much for your elaborative answers.
The first thing is to have basic information of these forests, for example about 20 years ago, and be able to compare with their current density and distribution of species, both flora and fauna and associate the changes found with anthropic intervention or climate change .
