COSEWIC Status Appraisal Summary on the Ottoe Skipper Hesperia ottoe in Canada ENDANGERED 2015 COSEWIC status appraisal summaries are working documents used in assigning the status of wildlife species suspected of being at risk in Canada. [...] In 2005 and 2006, Dakota Skipper surveys were carried out as part of a study that compared the habitat of the Tall Grass Prairie Preserve (TGPP) and the Interlake region of Manitoba to assess the suitability of reintroducing Dakota Skipper to the TGPP. [...] One of the greatest threats to Ottoe Skipper is conversion of the remaining fragments of native prairie for agriculture. [...] Detrimental changes to the plant community from overgrazing may include the direct removal of nectar and larval sources as well as soil compaction, changes in soil moisture and condition, and trampling of larva (McCabe 1981, Dana 1997, Royer and Marrone 1992, Swengel and Swengel 1999). [...] The chemical control of Leafy Spurge in 2004 near the Aweme site resulted in the direct loss of Ottoe Skipper nectar sources that were abundant in the mixed-grass prairie (COSEWIC 2005).
