Regarding: Canary island pines at 10072 Firwood
I was asked to evaluate 3 Canary island pine (Pinus Canariensis)in the bacic patio area of the
residential property. They are growing in a raised planter at the back of the property. The trees
appear to be healthy with no apparent disease or insect problems. They range in height from 35
to 70 feet tall with trunk diameters of 18, 12 and 12 inches. These trees have cones that can
range from 4 to 9 inches long.
The planter is 40 inches high,42 inches wide (back of wall to the fence in back of the trees)
and 32 feet long. The wall is made of cinder block cemented together. The wall is starting to
show signs of cracking and looks lilce it is starting to be pushed out at the top. There are a
number of roots visible growing against the top of the wall.
If the trees are not removed there will be more damage to the wall with a possibility of it
breaking in places. I don't think building a new wall farther away is practical as it takes away
from the outdoor living space that the patio provides. In addition the falling cones make it
hazardous to enjoy the patio. I believe that these trees were a bad choice for this location
(wrong tree in the wrong place).
My recommendation would be to remove the trees and replace with a tree species more
suitable to the available area. Trident maple (Acer buerger^ianum), a tree that grows to 25 feet
tall and 20 feet in width would create a good canopy for that area without overgrowing it. I
would also suggest a 1 to 1 replacement ratio because of the limited space available.
