Across the city we manage and maintain 36,000 street trees.
Many of these trees were planted in the Victorian era and are reaching or have reached maturity.
Another large group of trees are cherries planted in the 1960’s, which reach maturity quicker than some of the larger species planted in the Victorian era.
An independent tree survey carried out in 2006/7 concluded that over 75% of the city’s street trees were mature or over mature and only 5% were young trees.
In 2009 we received the approval to let a 25 year Highways PFI contract and in order to prevent a catastrophic decline in our street trees, funding was allocated as part of this contract to enable us to better maintain and start to replace street trees.
This will help us ensure that street trees were there for future generations.
This work is being carried out as part of the wider upgrade works that commenced in 2012 and are now underway across the city.
In addition to the independent tree survey, another survey of the city’s street trees was carried out in 2012.
This survey, which was conducted at the start of the Streets Ahead contract, identified those trees that were:
Of the 36,000 street trees, just over 1,000 were classified in these categories in 2012.
This survey also helped identify what maintenance was required for each of the street trees, with in excess of 6,300 pruning and maintenance jobs being raised at this time.
As trees are living organisms, their condition can change from year to year, the city’s street trees are surveyed every 4 to 5 years and the maintenance programme is constantly being updated as required.
As part of the Streets Ahead work, in 2012 we developed our 5 Year Tree Management Strategy.
This strategy outlines the Streets Ahead teams’ strategic approach to maintaining and managing the city’s street trees.
We work hard to manage and maintain the city’s 36,000 street trees.
We do this by using qualified tree experts who have assessed all the street trees.
Those trees that will benefit and thrive from further maintenance and other treatments including, crown lifting, crown thinning, crown reduction and general pruning will be placed into a cycle of maintenance.
All Streets Ahead tree assessors hold current professional tree inspector qualifications from LANTRA, this is the UK’s Sector Skills Council for land-based and environmental industries.
All Streets Ahead assessors are also qualified in arboriculture.
The Arboriculture team has over 100 years combined experience in this field and have all worked on the management of street trees for a large proportion of this time.
More specifically they have all worked on Sheffield’s street trees for many years both for Streets Ahead and before that for Street Force.
We are unable to carry out tree works where:
The city’s street trees are assessed to establish their health and condition.
If a tree on a street is found to fall into the 6D criteria then our maintenance contractor, Amey, will seek approval for it to be replaced.
The exception to this is if the tree is deemed to be an imminent danger to property or users of the highway network.
We are committed to replacing street trees on a one for one basis.
This means that for every tree that meets the 6D’s criteria and needs to be removed, it is replaced with a species of tree that is better suited to a street environment.
We are also replacing some of those trees that were removed before the Streets Ahead contract began which means that there will be an increase in the number of street trees at the end of the Streets Ahead contract in 2037.
The majority of street trees that have been removed to date have fallen into either the dangerous, dead, dying or diseased category.
These not have provided a substantial amount of canopy cover.
Sheffield has over 4 million trees across the city and the street trees make up less than 1% of the trees in the city.
We employ trained ecologists who check all trees before they are removed.
The ecologists will assess the tree before it is surveyed to establish if any birds are nesting in it or if any bats are roosting in the tree.
The trees are then checked again on the day the removal is planned.
The ecologist will attend site with the arboricultural team and visually inspect the tree as well as carrying out inspections in the canopy of the tree.
