An interactive map showing the locations of more than 650,000 trees in Jersey has been published
The map, which includes trees over three metres tall, allows users to zoom in to pinpoint individual
trees, and gives a representation of overall coverage in the Island. There is also the ability to get an
estimate of canopy areas and heights.
It has been created from aerial photographs and a LIDAR survey taken in 2021. A number of similar free map layers already exist on gov.je, including for recycling centres, school catchment areas and
Minister for the Environment, Deputy Jonathan Renouf, said: “Trees are part of Jersey’s rich natural
history, and they are a vital part of our environmental future, so it’s positive to see their wide
distribution now compared with records from the middle of the last century.
“Trees each have their individual unique value, but what this map shows is the broader Island-wide
perspective and highlights, for example, their role as corridors for biodiversity. In our small Island,
trees, hedging and woodlands collectively provide our wildlife the habitat they require not only to
survive, but the resources to thrive.
“The Jersey Tree Map reflects the efforts of many Islanders to plant, protect and nurture our trees,
hedges and woodlands. The map provides a benchmark against which we can measure how well
we continue to protect and enhance Jersey’s natural heritage.”
The analysis generally provides more accurate estimates of canopy cover and height for single
trees in open spaces than for groups of trees or woodland. It is likely that some manmade objects
as well as some larger shrubs, bushes and hedgerow will be incorrectly shown.
