Climbing prairie rose (Rosa setigera) COSEWIC assessment and status report addendum: chapter 12

Existing protection or other status designations and Summary of status report

Existing protection or other status designations

The Nature Conservancy gives this species a global rank of G5, a national rank of N2N4 (USA) and N3 (Canada); there are two states where it is listed as imperilled (S1 in Virginia and S2S3 in Michigan) and two states (Iowa S3 and Georgia S3?) and Ontario (S3) where it is listed as vulnerable. For four nearby states it is listed as unranked (S?): Pennsylvania, Ohio, Indiana and Wisconsin. In no state is it listed as secure (S4 or S5) by the most recent listing of 2001, accessible through the NatureServe web site.  

It is listed as a species of Special Concern by the Committee on the Status of Endangered Wildlife in Canada (COSEWIC) but is currently without formal protective status in Ontario.

Summary of status report

Where comparison of current population counts to past estimates is possible, the evidence summarized in Table 1 suggests a decline in numbers of individuals (25%) and occupied habitats (38%). Of the known sites, both from actual counts and estimates of others not surveyed, it is estimated that there are about 145 individual mature shrubs of this species. It was observed to colonize and thrive in early successional old fields and other open habitats, thus there are likely undocumented new populations, possibly reducing the severity of this observed decline.

As pressure increases to develop natural areas around Windsor and at other sites, this species will be in greater jeopardy. However, with better awareness and more sensitive land management, the jeopardy could be greatly reduced. Much of the activity that is causing the loss or decline in populations could be modified to protect this species and other species of plants and animals in jeopardy in open habitats. For example, mowing or herbicide spraying of open meadow habitats, trenching and brush clearing operations along ditches and roadways, parking and trail construction in parkland, and unrestricted use by all terrain vehicles (ATV) operators.
