Housing developers could face stricter regulations after allegedly allowing hundreds of newly-planted trees to die.
It is claimed the trees – planted by Persimmon Homes South West and Redrow Homes as a condition of planning permission – have died in two out of the three urban extensions in Somerset.
Councillor Mike Rigby said Somerset West Council needed to improve its monitoring and enforcement capacity.
Both developers said they were working to rectify the issue.
According to the Local Democracy Reporting Service (LDRS), as part of any approved housing development, it is common practice for the council and developer to agree a scheme of planting and landscaping.
