HOA deforestation campaign

hi r/treelaw, my aunt's HOA board (location: new york state) has declared that they want to cut down all of the trees in between the condo units in their gated community. my aunt is devastated because she has three huge and healthy cherry blossom trees next to her unit. she is also worried about the loss of shade impacting her A/C costs in summer, her property value in the future, and the increased common charges to pay for all this landscaping. is there anything to prevent them from deforesting the whole development for no reason? she has already tried to get onto the HOA board but did not succeed. what can i look into to help? apologies if this is not right for the subreddit.
