Paul Bowman was one of the co-authors of the Flora of Hampshire, published in 1996. He was a founder member of the Hampshire and Isle of Wight Naturalists Trust and was the botanical recorder for South Hampshire (vice-county 11) for about 20 years.
After his death in 1999, his vast collection of about 5000 Hampshire plant specimens, along with his files of collection data, referees and determinations came to the Museums Service. As the plants were housed in newspaper, these are currently being mounted onto herbarium paper prior to cataloguing and re-housing. About 3,467 have been catalogued to date.
