Books about Trees
Because conifers logically belong to trees and shurbs, this page includes
coniferous trees and shrubs, even though they are not flowering plants.
The Native Conifers of North
America. Nearctica.com. A complete introduction and field guide
to the conifers of North America including individual species accounts
for all of the North America species, photographs, line drawings, and
distribution maps. You'll also find keys to genera and species and non-technical

parts of the continent. There's even a calender you can print with different
species of pine cones.
GENERAL
 Silvics
of North America. U.S. Forest Service. Silvics of North America is
a Department of Agriculture Handbook now available through the internet.
The handbook comes in two volumes, one covering the conifers and the other
the hardwoods. Not all tree species are covered in the handbook, although
the majority are. Each species has its own page and the information covered
include the species native distribution, some identification characters,
habitat, physical requirements, life history, abundance, pests, uses,
and an extensive bibliography. A truly incredible piece of work and anyone
interested in trees should take a look.
Atlas
of Relations between Climatic Parameters and Distributions of Important
Trees and Shrubs in North America. Robert W. Thompson et al., U.S.
Geological Survey. A magnificent resource for anyone interested in the
distribution of trees in North America. Each tree species (and most are
covered) consists of a single Adobe Acrobat (pdf) document containing
a distribution map for the species and a series of graphs depicting the
physical requirements of the species. Mexican species are covered in addition
to U.s. and Canadian species. A tremendous resource.

shrubs, mostly eastern and midwestern species.

the individual species. This is a magnificent and highly informative site.
Trees
and Shrubs of Alabama and the Southeast. Lisa Samuelson et al. A great
site on the trees and shrubs of the southeastern United States from Auburn
University. Each of the species is covered in a separate page with a description
of the species and its biology and a series of one or more pictures.

information such as its natural habitat, propagation, and growing conditions.
The site is intended to be horticultural and not all of the trees listed
are native to North America.
Pine
Cone Identification Page. This site opens with an image map of conifer
cones. You click on a cone matching the one you wish to identify to get
more information. This otherwise very useful site is weakened by a very
large and slow to download image map of nearly 600K. In addition the map
does not fit the screen and you must scroll right to see all of it. This
page includes both native and cultivated species.

Tree Book. Minnesota Power. This is primarily a horticultural site,
but is has useful information and photographs on a number of North American
tree species.

many of its components were absent. The site proposes to cover the trees
of North America and the tree families of the world. At present you'll
find a list of the tree families of the world, and tree genera and species
of North America although the information on each tree species is presently
very spotty.

of New Brunswick. Photographs of various parts of some species of trees.
