Seed production of a forage legume in the natural pastures reflects its ability to reseed and enrich the pasture. This study aimed at improving the productivity and nutritional value of pastures through enhancement the ability of leguminous species to restore pastures under phosphorus management. A field study was conducted at the research station of Farako-Bâ, Burkina Faso.

We investigated the endozoochorous seed input by cattle and sheep on a pasture located in the western region of Burkina Faso. Through germination experiments, we assessed viable seed content of the dung of these grazing animals to estimate their suitability and efficiency for seed dispersal of fodder legumes.

- Fire has a significant impact on herbaceous vegetation, with increased abundance observed after fires at various global sites, particularly in wetter and cooler ecosystems.
- In savannas, the response to fire is much stronger than in forests, with herbaceous vegetation being 4.8 times more abundant in burned areas compared to unburned ones.
- The study highlights that fire plays a crucial role in maintaining the vegetation structure in both savanna and forest ecosystems, affecting grass cover differently in these environments.
The distribution of dryland trees and their density, cover, size, mass and carbon content are not well known at sub-continental to continental scales. This information is important for ecological protection, carbon accounting, climate mitigation and restoration efforts of dryland ecosystems. We assessed more than 9.

Knowledge about aboveground vegetation and species composition of soil seed bank and the processes that contribute to vegetation recovery on and surrounding watering points subjected to grazing is lacking. Successful restoration strategies hinge on addressing these knowledge gaps.

- Agroforestry parklands in Burkina Faso are under threat from demographic and climatic pressures, putting indigenous tree species, vital for income and nutrition, at risk.
- A study identified 16 key food tree species and analyzed six major threats, including climate change and overexploitation, to prioritize conservation efforts.
- Recommendations include using tree populations from 'highly threatened' areas for ex situ conservation and suggesting assisted regeneration for trees in suitable habitats facing immediate threats.
