Data from: Contemporary distribution of non-native Chinook salmon (Oncorhynchus tshawytscha) in South America

<p class="MsoNormal"><span>The dataset incorporates information on Chinook salmon occurrences by basin in South America, which was obtained from the literature and from unpublished information obtained from research monitoring efforts conducted in Chile, Argentina, and Uruguay. The information was divided into two periods: historical (prior to 2006) and contemporary information (2006 onwards). Year or range of years in which the observation was taken was also included. This dataset was used to construct Fig. 1 of the manuscript "<span class="fontstyle0">Contemporary distribution of non-native Chinook salmon (</span><em><span class="fontstyle2">Oncorhynchus tshawytscha</span></em><span class="fontstyle0">) in South America</span>".</span></p>
