Rare Plant Distribution Modelling: Exploring Environmental Predictor Datasets - A Case Study in Southeast Alberta.

Rare plant distribution modelling is becoming more commonly used in to inform conservation management. Challenges in modelling are associated with uncertainties in biases that exist or are introduced in source datasets, knowledge of rare species ecology, knowledge of modelling techniques, and data handling methods. These biases persist in model output and the effects of these on model performance must be understood when applying them to various conservation management scenarios.

Through a case study in southeast Alberta, the distribution of Moquin’s sea-blite (Suaeda moquinii (Torrey) Greene), a rare grassland sub-shrub, was modelled with a focus on exploring environmental predictor datasets. Results showed that biases were reduced in the modelling study design through data handling methods, validating predictions with field observations, and comparing different predictor data treatments. However, biases persisted and the implications of these on different conservation management scenarios were identified.
