My favourite quotes.

The trees are God's great alphabet:
With them He writes in shining green
Across the world His thoughts serene.
~Leonora Speyer

God has cared for these trees, saved them from drought, disease, avalanches, and a thousand tempests and floods.  But he cannot save them from fools.  ~John Muir


If trees could scream, would we be so cavalier about cutting them down?  We might, if they screamed all the time, for no good reason.  ~Jack Handey


The groves were God's first temples.  ~William Cullen Bryant, "A Forest Hymn"

For in the true nature of things, if we rightly consider, every green tree is far more glorious than if it were made of gold and silver.  ~Martin Luther

The best time to plant a tree was 20 years ago.  The next best time is now. 
The true meaning of life is to plant trees, under whose shade you do not expect to sit.  ~Nelson Henderson

As the poet said, "only God can make a tree" - probably because it's so hard to figure out how to get the bark on.  ~Woody Allen


I think that I shall never see
A poem lovely as a tree.
A tree whose hungry mouth is prest
Against the earth's sweet flowing breast;
A tree that looks at God all day
And lifts her leafy arms to pray;
A tree that may in Summer wear
A nest of robins in her hair;
Upon whose bosom snow has lain;
Who intimately lives with rain.
Poems are made by fools like me,
But only God can make a tree.
~Joyce Kilmer, "Trees," 1914
