Niche models were fitted iteratively between 2015 and 2020 followed by field validation of the predicted suitable sites with focus on suitable sites adjacent to the known locations of Ivesia webberi. True absence points and new locations discovered during field validations were added to the spatial datasets for subsequent niche modeling iterations. This resulted in a significant improvement in the predictive accuracy of the niche models and resulted in the discovery of novel locations and expansion of the range of the threatened plant species.
