I’m glad you picked up on this. Perhaps someone on the listserve has a contact with Philadelphia Parks and Rec.
My personal view is that we might want to try to move towards something of a white-list type of advice where MAIPC or others could work towards getting these lists moved more and more towards native species and non-invasives (dare I say, that have gone through “extreme vetting?” I dare). If we could get some evidence-based information on where these non-natives have been used and for how long, it might be reasonable to give them a different designation than less well studied non-natives. I see this approach as entirely a pragmatic one (I’d prefer that nurseries produced far more diversity and abundance of native species so that they would be easier to recommend or mandate) - but at least this approach could make some inroads towards these types of plantings doing less damage and it might be more successful than a full frontal assault that could be more easily ignored and would be difficult to implement at best.

Subject: [MAIPC] Philly Street Trees
My roommate was applying for an internship with them and came across the list of approved Philly street trees. Recently Philly has made a push for more planting similar to NYC's. Well, she knows a lot about invasives due to her proximity to me talking about them. We were very disappointed to find a number of non-natives (regionally non-native as well). Other than crabapples (which I can't tell what species they are since they are all cultivars), I didn't immediately recognize any as commonly naturalizing, but as we all know that doesn't mean much for the future, and doesn't do as much for the environment anyways.
So I was wondering what we could do as an organization (aside from me writing a letter to them since I live here). An impact here could make a huge difference given the geographical size of the city. Perhaps any contacts with NYC million trees program could be useful. Here is the list:
