The survey, part of the HTA's Greening the UK campaign, includes questions about the quantity of green spaces and trees in urban areas, planting in new developments, flooding and green roofs.
Speaking at the Palmstead Nurseries soft landscaping workshops last week, HTA business development director Tim Briercliffe gave an insight into research findings.
More than 100 local authorities have already responded to the surveys, and a full set of results will be available in mid-October.
At the Coles Nurseries Unearthed event on 11 September, another HTA representative, business development manager Martin Simmons, told attendees: "Evidence shows the amount of planting has fallen, but 56 per cent of councils think it has actually increased."
This mismatch, along with results showing that 70 per cent of councillors claim developers have not delivered planting as outlined in approved planning applications in the past year, reveals there is still much work to be done.
Other results show that 51 per cent of councils do not encourage residents to get involved in community planting schemes, and 61 per cent say developers' standards are never checked.
Fifty per cent of respondents say that only a few or no streets in their area have trees planted on them, while eight per cent have no idea what a green roof is.
The HTA is set to join the Landscape Institute's immediate past president Nigel Thorne to meet with CABE Space director Sarah Gaventa and head of public space management and best practice Nicole Collomb on 24 September to discuss the campaign.
- The HTA is sponsoring a Labour Party/Fabian Society conference fringe event on 23 September in Manchester entitled: Can Politicians Save the Planet and Get Re-elected? The panel includes Defra minister Hillary Benn, former home secretary Charles Clarke MP, Greenpeace executive director John Sauven, IPSOS Mori research head Julia Clarke and RSPB climate change head Ruth Davis.
