Accounting for uncertainty when mapping species distributions: The need for maps of ignorance

Abstract: Accurate mapping of species distributions is a fundamental goal of modern biogeography, both for basic and applied purposes. This is commonly done by plotting known species occurrences, expert-drawn range maps or geographical estimations derived from species distribution models. However, all three kinds of maps are implicitly subject to uncertainty, due to the quality and bias of raw distributional data, the process of map building, and the dynamic nature of species distributions themselves. Here we review the… Show more

“…While the concepts associated with error and uncertainty propagation have been studied in the geospatial literature (Fisher and Tate, 2006;Wilson, 2012), the attempts to raise end-users' awareness in fields like ecology and environmental modeling have failed (Brown and Heuvelink, 2007;. With a few exceptions from the terrestrial literature (e.g., van Niel and Austin, 2007;Livne and Svoray, 2011), and despite repeated calls for the appropriate consideration of error and uncertainty propagation in environmental modeling and mapping (Rocchini et al, 2011;Beale and Lennon, 2012;Lechner et al, 2012), these concepts have yet to be better implemented, especially in a marine context .…”

“…However, subjectivity would be removed if complete metadata including quality information would be associated with each dataset, enabling a robust data quality assessment. Rocchini et al (2011) and Diesing et al (2016), among other authors, have highlighted the need for maps of ignorance, i.e., maps that spatially display uncertainty and errors associated with the primary maps and can assist decision-makers in assessing the reliability of predictions. While some tools have been provided to assess individual components of data quality [e.g., Combined Uncertainty Bathymetric Estimator (Calder and Mayer, 2003); Data Uncertainty Engine (Brown and Heuvelink, FIGURE 3 | Example of how using data of different quality can produce different outcomes.…”

“…Non-analogous climatic conditions within projection areas exceeding those that a SDM was trained for, may reduce the reliability of predictions (Fitzpatrick and Table 1.CH, Chyulu Hills; TH, Taita Hills. Rocchini et al, 2011). This potential source of uncertainty was quantified in a spatially explicit way in each scenario by using multivariate environmental similarity surfaces (Elith et al, 2010).…”
