Community & Cultural Services Department Public Landscape Division 2600 Ocean Park Blvd. Santa Monica, CA 90405 (310) 458 8974 ph (310) 399 6984 fx NOTICE OF INTENT TO REMOVE DECLINING CITY STREET TREES Date: February 27, 2012 The Public Landscape Division of the Community & Cultural Services Department will be trimming the street trees on Euclid Street in the next few weeks. In conjunction with the trimming, trees that are in a state of decline will be removed. The declining trees on Euclid have a permanent and progressive reduction in health, vigor and structural stability that will lead to its death or structural failure. These declining trees are over mature and suffering from old wounds and other impacts that have interrupted the living system. This has resulted in impeded growth followed by the depletion of energy reserves normally stored in the root mass. When this occurs there is an overall reduction of health, condition and stability that is followed by the death of the tree. Additional information that details the reasons for the individual removals can be found by going to www.santamonicatrees.com The removals are located at: 1836 Euclid Street Holly Oak (Quercus ilex) 1942 Euclid Street Holly Oak (Quercus ilex) 1938 Euclid Street Victorian Box (Pittosporum undulatum) The replacement trees will be the Cork Oak (Quercus suber), planted as part of the City s Fiscal Year 11/12 planting program. For questions or concerns regarding this matter call: Walter Warriner, Community Forest & Public Landscape Superintendent or Johnny Aguila, Community Forest Supervisor at (310) 458-8974.

1836 Euclid Holly Oak (Quercus ilex) This canopy s sparse foliage is an indication of a damaged root system. The tree is unable to supply its canopy with adequate moisture to produce new leaf growth. Without the new leaf growth the tree has no energy resources through the photosynthetic process to produce new root growth. With the loss of energy reserves 1836 and Euclid, the inability con t to produce new carbohydrates, this tree is now in a spiral of decline. The tree s condition will continue to deteriorate until complete failure occurs.
1836 Euclid Holly Oak (Quercus ilex) con t Insects infested this tree by entering old wounds. These insects transmit disease pathogens that weaken the already stressed tree, making it subject to further insect infestation and disease attack. Loose, cracking bark is a sign of the tree s lack of moisture uptake as a result of damaged roots.

1938 Euclid Street Victorian Box (Pittosporum undulatum) Dieback in the canopy of this tree is the response to a weak root system. Dieback typically begins at the tips of the branches and works its way down into larger limbs and continues into the main stems. As the dieback 1938 progresses Euclid the Street potential con t for limb or complete tree failure then follows with the possibility of private property damage or personal injury.
The concrete surrounding the trunk base restricts the growing space and inhibits proper root development. When the balance between a root system and the canopy cannot be maintained, the tree responds with poor growth, overall decline and eventual failure. 1938 Euclid Street con t
The sparse canopy is the product of the tree s inability to take up adequate moisture due to the tree s root restrictions.
