Vilnius starts the annual inventory of plantations – the trees of the city, their species and diameter are recorded, their condition is assessed and maintenance is planned. On the public land all plantations are inventoried, while on the private land – only the trees to be preserved are inventoried.

In the central part of the city, trees have already been inventoried. This year, it is planned to inspect the trees in Vilkpėde, Paneriai, Rasos, Naujoji Vilnia, and to update the inventory of trees in Antakalnis.

In total, around 500,000 trees have been inventoried in the capital. According to the inventory, maples (86,000), lindens (25,000), birches (33,000) and pines (32,000) account for the largest number of trees in Vilnius. The vast majority of them are in a satisfactory condition. A further 80,000 plantations are planned to be inventoried this year.

“Inventory of plantations is essential for assessing their condition and planning maintenance. It is also important to mark protected trees on the private land,” Gintautas Runovičius, Head of Urban Environmental Management Division of Vilnius City, emphasised.

The municipal enterprise ID Vilnius is responsible for the inventory. It is carried out by specialists physically walking around the city and entering the information directly into the database using a mobile app. Trees to be inventoried on the private land include oaks, ashes, maples, elms, hornbeams, field elms, beeches, fluttering elms, lindens, larches, birches and pines with a trunk more than 20 cm thick at a height of 1.3 metres.

The applicable legal acts establish that residents must allow access to the site by tree inventory technicians upon presentation of their work certificates and identity documents. The inventory will continue until 1 November.

Technicians who examine plantations visually inspect each tree individually – assessing the condition of plantations, describing their physical parameters, and recommending management measures based on data collected and conditions of the area where they grow.

The condition of plantations is determined by assessing the intensity of tree pruning, the presence of any diseases or pests and, if they are present, their amount and disease intensity; whether the trunk of the tree is damaged and how seriously, whether the tree is straight or leaning, and the degree of leaning. Finally, the area under the tree (its growth area) is assessed to see whether roots have enough space and are not restricted.

Plantations of the city are inventoried according to the Rules for inventory and registration of plantations and green areas approved by Order of the Minister of the Environment.
