View Pruning:

Objectives might include thinning and “opening windows” in the crown to expose key landscape elements such as ridge lines, mountains, and water while retaining screening from the neighbor’s roof. Conifers with dense pyramidal crowns can beĀ  “aged” by leaving limbs clumped along trunks with direct views in the gaps. In either case, the tree remains to frame the view, avoiding topping or removal.
