Hi Brian, Ok, I didn't realise Andy had offered off-list.
Here's one bit of work I did mapping trees: http://tom.acrewoods.net/2011/04/19/maps-open-data-and-activism-on-the-heygate-estate/ It's also worth reading this report, particularly the section from paragraph 4.11, which gives some idea of the context of street tree data collection and availability by councils: http://www.london.gov.uk/sites/default/files/FINAL%20street%20trees%20report%20010611.pdf Since then a few councils have released some more semi-open data (encumbered by the usual uncertainties around OS licensing), but they aren't doing so in a way that makes it easy to track whether threes have been planted or felled, and few councils give useful open data on attributes like height, circumference and canopy size that would enable someone to estimate the spread of roots.
