od of 1862-1872. The “'historical reconstruction'” design approach required the removal of three
large groves of nonnative eucalypts ( Eucalyptus spp.), which had come to dominate the canyon
floor within the project area. The project team used archival photographs and lithographs, as
well as historical information provided by preserve staff and the Friends of Los Peñasquitos Can-
yon Preserve (FLPCP). The historic photographs illustrate that the site was occupied by riparian
vegetation, including sycamores, cottonwoods, mulefat, and oaks along the banks of the creek. In
addition, the project team made use of field survey records from other nearby streams.
In return for using parklands to mitigate a public project, the County Parks Department also
required that the project team remove several volunteer palm trees that had grown adjacent to and
in the historic Spring House (fig. 14-3), which were beginning to undermine the foundation of the
house. However, five historic Phoenix palms planted at a nonthreatening distance from the Spring
House would be preserved.
