Seasonal pattern in browsing trees and shrubs by reintroduced Cuvier's gazelles: a study in Morocco with management implications.

Cuvier's gazelle () was reintroduced in Tergou reserve (TR) in 2018-2019 to help restore its population at the Moroccan Central Plateau. A study on browsing trees and shrubs was conducted in this reserve to identify (i) the seasonal pattern of this activity and (ii) the most solicited tree and shrub species. Here, we used six random 500-m transects to collect, each month and at each transect, the number of fresh browsing traces of each encountered tree and shrub species. We used principal component analysis (PCA) and linear regression model (LM) to test seasonal variation of the composition of trees and shrubs browsed. Our results showed that, in this reserve, , , , and are mostly browsed during winter, whereas and are mainly used during spring. This information is useful to the managers of the TR not only to consider the importance of the aforementioned trees and shrubs for reintroduced gazelles but also to take the necessary measures so that the forest stand of this reserve is maintained at an appropriate level. Thus, the pursuit of monitoring is necessary to understand the bio-ecology of this semi-captive population more deeply. For this reason, the TR remains a useful and appropriate reference framework offering the opportunity for consolidating and improving the knowledge on this vulnerable mammal species in the view of a future successful release in the wild.
