The topics covered in this guide include: tree values, principles of tree growth, planning, tree selection, site preparation, planting and early care of trees, maintenance of established trees, handling trees affected by development, utility forestry, and the politics of municipal tree care. Citizens, government decision makers, land developers, and workers out on the streets will all find this guide useful. It is written for anyone in the private or public sectors who cares enough about their environment to see that trees in their community are planted, valued and protected.
