Bullsmoor park is also not mentioned at https://www.enfield.gov.uk/services/leisure-and-culture/green-enfield which is the most obvious official place for the name.

However, there is mention of Aylands Park at https://www.enfield.gov.uk/services/your-council/enfield-news-summer-2023 and noting the name of the allotments in the centre of the area, I wonder whether this is more likely to be its official name.
