what to do about this kind of abandoned area

Need to get some thoughts out in a concrete way before I can focus on doing homework. 

There's this little area of native plants that have been mostly stuck in the ground and then left to fend for themselves. I've mentioned it before. Recently learned I someone at the nearby garden would like to take them out and put a fruit tree in instead. I see the value of a fruit tree but I really feel like our native plants are important and they are contributing to the pollination we get in the vegetable garden. So, ok perhaps foolishly, I'm thinking maybe if I take care of it people will see that it can be idk beautiful, useful, whatever they want to see it as. 

Here's what I need to do if I want to take care of it:

-remove the nothoscordum

-remove the milk thistle and dandelions

-remove the invasive mint

-put protection around the smaller plants so the city workers don't weed-whack and kill them

-add: Wildflowers, native milkweed would be great too

(voice of the jingling fool) that's only 5 things!

Ok so obviously I'm not winning the Nothoscordum gracile battle. but I can cut - not pull - the leaves and help starve the bulbs out. sure they'll still be there but it won't be AS bad. Maybe.

i've made a dent in the milk thistle and the invasive mint. it's just about consistency. 

I have some chicken wire at home I can cut into cylinders and use in conjunction with those metal irrigation stakes to hold them into the ground so that if anyone DOES try to use a weedwhacker on them they will at least get somewhat fucked up. 

I have Clarkia seeds this year. kind of too many. I'll go through my collection, and wait for rain. 

OH I could also do a little pruning. I'll trim back the salt marsh heliotrope, it can take that and it is getting... a little out of control. and if there are dead branches on the mallows maybe i remove them? I just have to find time to do all these things (small screams) but let's GO.
