Plant Stewardship Index Calculator

In the process of upgrading the Bowman's Hill website, we have been having problems with some aspects of the PSI Calculator. Please be patient as we work to resolve these difficulties and return the site to complete (and expanded!) functionality. Our apologies. If you have specific problems, please call the PSI coordinator at 215-862-2924.

IMPORTANT NOTICE: The Plant Stewardship Index Calculator at Bowman's Hill Wildflower Preserve is being retired. (BHWP-PSI)

A new public Floristic Quality Assessment Tool is available at the following location:

All assessments entered prior to November 2016 in the Bowman's Hill Wildlife Preserve psi index are being transfe1Ted to the Universal FQA Calculator. The Universal FQA Calculator is an open source online tool for ecological assessment containing public Floristic Quality Assessment databases from different areas of the country. The PA and NJ databases from the BHWP-PSI are now available there for your use.

If you have created any assessments using the BHWP-PSI tool, you will receive an email when the transfer is complete. It will be sent to the email address used to log in to the BHWP-PSI site.

The data that is currently available here on the BHWP-PSI will continue to be available for access, reporting and download until May 31, 2017. Any edits to assessments that are made at this time, WILL NOT be updated on the Universal FQA site. For this reason, if you plan to edit any existing assessment lists, this should be done at the new universal FQA site.

No new assessment lists should be added at this time. Any changes made to your account or list information will exist only on this site and will not be available once this site goes offline on or about May 31, 2017.
