On the Presidio Parkway website’s Construction FAQ page, there’s a relatively new post about the Pet Cemetery:

What will happen to the Pet Cemetery during construction?
The Pet Cemetery was designated an environmentally sensitive area and was fenced off and protected during construction. The Swords to Plowshares organization has initiated a volunteer program to maintain the cemetery in partnership with the Presidio Trust. Later in the year, the girders that protected the Pet Cemetery during construction will be removed, and access to the Pet Cemetery will be restored.

“Later this year” tells me that this FAQ has been updated: the protective cover is all that remains of the falsework, the Doyle Drive construction having been completed.  But how had we missed this note about the Swords to Plowshares organization?  Are they on deck to maintain the site?  Looking for information I find the following in a 2015 Inverse article:

In the past, Swords to Plowshares, a non-profit in San Francisco that provides “wraparound care” for military veterans, contributed to the cemetery’s upkeep.

Asked to provide comment, Brian Jarvis, an associate with Swords to Plowshares, says, “Our history with the Presidio Pet Cemetery is limited to a group of informal volunteers who took it on themselves some years back to maintain the cemetery while living at our nearby Veterans Academy, until they either moved on or were no longer physically able to do so. To my knowledge they are no longer involved.”

“Some years back” may refer to this from a 2010 article on the presidio.gov site, “Swords to Plowshares Vets to Help Care for Presidio Pet Cemetery”:

The Presidio Trust and the Swords to Plowshares Veterans Academy, located on the Presidio, are kicking off a new partnership that will ensure long-term stewardship of the Presidio Pet Cemetery. The agreement provides for Trust staff to work with residents at Swords to Plowshares’ permanent supportive housing facility, the Veterans Academy, to maintain and improve the cemetery. Activities will include pulling weeds, removing invasive plants, picking up trash, trimming shrubs, and eventually restoring individual grave markers.

Phase II of the Doyle Drive project, which began in 2012, included the construction of the protective cover.  So, the partnership must have lasted only a few years.  What next?
