I’ve found that the best way to assess the impact of the removal of trees is not to do it at all, at least not consciously.

If, after a tree has been trimmed or felled, I do not notice anything different, then usually I conclude that removing it was the right thing to do.  This has happened in the past when a tree was removed while we were away.  When we returned, we did not immediately realize that the work had been done.

Alternatively, if I do become aware of the change, it becomes a question of how I become aware of it.  For example, if I get the feeling that something is missing, that there is an unnatural gap in the treescape, it can mean that the removal was too extreme or not well chosen.  Luckily, this has not happened to us very often and fortunately, when it has happened, the surrounding trees eventually grew in to fill the void.

If, however, I get a feeling of openness—sunlight or airiness where there was none before—or notice a new and exciting view, previously obscured, then we probably made the right choice.  This was the case today.

With the two trees gone, the garden remains in the sun until after 6 o’clock, an extension of the growing day of at least three hours.  As an added bonus, we can now see a vignette of the surrounding mountains, framed by the remaining trees.
