Lebanon biogeography outlined by tree and shrub species distribution pattern

This dataset contains environmental study data on various tree and shrub
species in Lebanon. The research examines multiple environmental factors
influencing species distribution and presence. Occurrence points were
collected from field surveys under various studies, covering Lebanon. We
used all the presence points and consistent environmental variables called
predictors to conduct ecological niche modelling and further use the
outcomes of the predicted distribution of tree and shrub species to
outline Lebanon’s biogeography. The data referred to as
predictors for ecological niche modelling are the environmental factors
used for the study, retrieved from open sources. These include climatic,
topographic, and biogeographic factors and predictors retrieved from
remote sensing data such as cloud coverage, normalized difference
vegetation index, and land surface temperature. This information
is used to delineate suitability maps for each species and understand the
factors driving their distribution. In the next step, species were
classified based on their biogeographical appurtenance and grouped into
regional chorotypes. The produced heat maps in addition to dissimilarity
analyses allowed us to delineate the biogeographical zones and their
transition areas in Lebanon. Moreover, this data is being analyzed to
study vegetation variation across an elevation gradient.
