Nearly 70,000 trees have been planted in Glasgow over the last five years – and around 7,000 or more of them may already have died according to industry estimates.

The figures were revealed as councillor Stephen Docherty, Labour, asked questions about trees being added to the city and how many have survived.

There is a major push to make the city more leafy to help combat global warming and improve air quality.

The city’s efforts is equivalent to about 38 trees planted every day, which is 1.5 trees an hour.

Councillor Angus Millar, SNPs, said threats to trees can range from deer to insects and efforts to protect them include shielding them with plastic tubes.

He said it is thought 10 to 15 per cent of trees are potentially lost according to industry estimates.

Answering councillor Docherty’s question submitted at a full council meeting earlier this month,  Councillor Millar, SNP, said: “Glasgow City Council (GCC) and its partners including the Green Action Trust (GAT), the Conservation Volunteers (TCV), various schools and community groups and business volunteering activities have planted 69,620 trees over the past five years. All partners are supporting GCC projects.”

He added: “There is a wide range of different biological, chemical, and physical factors which have an impact on the growth and development of trees in the UK and while every effort is taken to ensure that the trees thrive the general indicative industry loss of 10 to 15 per cent for a new tree site is expected.”

The convenor for climate, Glasgow Green Deal, transport and city centre recovery said threats to trees include livestock, insects and pests, as well as bacterial, viral and fungal pathogens and vandalism.

He said: “Glasgow City Council works to minimise the percentage of losses by assessing if sites are suitable for planting and selecting the right tree for the right place.

“In addition, by adapting the composition of newly established woodlands, such as Cart & Kittoch, which was planted in 2020 to 2021 and including more variety and diversity in planting this will limit the impact disease may have newly planted species.

“As part of tendered works contractors, a maintenance period is also included within projects to assist with the establishment of the trees.”

He continued: “This could include, where applicable, trees having protected tubes installed, verification of planting for the first three years after planting and a twice-annual glyphosate application to the base of all trees will be applied for the first five years after planting, or until such a time that the trees are free from competition with other vegetation.”
