iTree:
A
combination of science and free tools that quantifies the benefits and values of trees.

i-Tree Eco version 6 is a flexible software application designed to use data collected in the field from single trees, complete inventories, or randomly located plots throughout a study area along with local hourly air pollution and meteorological data to quantify forest structure, environmental effects, and value to communities.

i-Tree Eco
is currently designed to provide estimates of:
  • Urban forest structure - Species composition, number of trees, tree density, tree health, etc.
  • Pollution reduction - Hourly amount of pollution removed by the urban forest, and associated percent air quality improvement throughout a year. Pollution removal is calculated for ozone, sulfur dioxide, nitrogen dioxide, carbon monoxide and particulate matter 2.5 (<2.5 microns).
  • Public health impacts – Health incidence reduction and economic benefit based on the effect of trees on air quality improvement for the United States only.
  • Carbon - Total carbon stored and net carbon annually sequestered by the urban forest.
  • Energy Effects - Effects of trees on building energy use and consequent effects on carbon dioxide emissions from power plants.
  • Avoided runoff - Yearly avoided runoff attributed to trees summarized by tree species or strata.
  • Forecasting - Models tree and forest growth over time; considers factors like mortality rates, tree planting inputs, pest and disease impacts and storm effects. Some ecosystem services including carbon and pollution benefits are also forecasted.
  • Bio-emissions - Hourly urban forest volatile organic compound emissions and the relative impact of tree species on net ozone and carbon monoxide formation throughout the year.
  • Values - Compensatory value of the forest, as well as the estimated economic value of ecosystem services.
  • Potential pest impacts - based on host susceptibility, pest/disease range and tree structural value.

In Tottenham seven trees were planted in a ring over 400 years ago for reasons lost in time; the Seven Sisters area and the underground station are named after them. The seven trees have been replanted a number of times, always by seven sisters. 

The Tottenham Trees logo, shown on the right, is a silhouette of the Bruce Castle Oak with the logo of the Charter for Trees, Woods and People launched in November 2017, on the 800th anniversary of the Royal Charter of the Forest.
