AND REPLACEMENT
Client / Property Owner: Apple Inc.
Site Address: 1 Apple Park Way, Cupertino, CA 95014, USA
Assignment
This report documents the condition of a Pinus eldarica located on the Apple Park campus
and provides professional recommendations regarding its removal and replacement to
support a permit application.
Tree Description
The subject tree is a Pinus eldarica (Eldarica Pine) measuring approximately 27 inches in
diameter at breast height (DBH).
Methods
The tree was evaluated using standard visual tree assessment methods consistent with ISA
Best Management Practices. Laboratory analysis of collected tissue samples was reviewed.
Findings
The tree is dead, exhibiting complete canopy failure, extensive branch dieback, and total loss
of vigor. Laboratory testing conWirmed the presence of Phytophthora spp. and Diplodia spp.,
both of which are known to cause mortality in conifer species.
Analysis
Phytophthora infection has caused severe root system failure, eliminating the tree’s ability
to uptake water and nutrients. Diplodia infection has resulted in shoot blight and structural
degradation. The combined impacts have led to the tree's complete mortality.
Conclusion
The subject tree is dead and has no potential for recovery. Its condition presents a high risk
of failure and poses a safety hazard.
