Service Recommendations Successfully Provide Habitat for Missouri Bladderpod
Midwest Region, May 16, 2007
Print Friendly Version
In March 2005, Missouri Ecological Services provided the Missouri Department of Transportation (MODOT) with conservation recommendations designed Missouri bladderpod (Physaria filiformis) habitat, which would offset habitat lost during bridge construction over the Little Sac River on Highway O in Greene County.


In coordination with the Missouri Department of Conservation (MDC), the Missouri Ecological Services Field Office requested that the site be monitored for five years to determine the success of plant establishment.


During monitoring of the site in 2007, six separate plants containing 16 flowering stems were documented. In a survey of the site last year, one large plant containing 100 flowering stems and numerous seedpods were found on the same glade. 


Due to habitat loss, the encroachment of woody vegetation and roadside maintenance, the Missouri bladderpod was listed as an endangered species on the Federal List of Endangered and Threatened Plants in 1987. 


Priority actions outlined in the Service‚Äôs 1988 Recovery Plan included the protection of existing sites and surveying  for new populations. The discovery of new populations in Missouri and Arkansas and the reduction in threats due to the implementation of various beneficial management initiatives led to the reclassification of the bladderpod from endangered to threatened in 2003.


Given the extreme variability in flowering and seed production for this species from year to year, the presence of bladderpod plants in 2006 and 2007 provides strong evidence that conservation recommendations made by the Service were successful.
