Abstract:
This dataset contains point locations of species in the genus Tamarix that have been combined from many disparate data sources. The data represent point locations with varying levels of accurracy recorded at various dates using different sampling methods collected by different organizations and individuals.
Purpose: The purpose of this dataset is to combine known point locations into a single dataset that can be used for ecological spatial predictive modeling.
