Giant redwood (Sequiadendron giganteum, then described as Sequoia gigantea), continuing a more extensive double row of these trees which was planted on the next landscaped block along Commonwealth Avenue to the northwest.  This broadly-spaced treatment, in contrast to the density of plantings on the sides of the car park proximate to Queen Victoria Terrace, provided a degree of visual permeability to drivers on Commonwealth Avenue during their final approach to the Parliamentary Triangle.
An additional row of American Elms was established on the western boulevard of the service road, directly opposite West Block, interplanted with mixed pairs of Mountain Ash (Sorbus aucuparia, then described as Pyrus acuparia) and Mexican Cypress (Cupressus lusitanica, then described as Cupressus knightiana).
The aerial photographic record indicates that a reconfiguration of the car park layout occurred at some stage after 1985.  Despite this, portions of the original car park planting layout have been retained to the present day, either in the form of original trees planted in the late 1920s, or as sympathetic replacements established somewhat later in the place of deceased original stock.  These retentions include much of the Pin Oak screen on the Queen Victoria Terrace side of the car park (likely comprising a mix of original and replacement stock), as well as a small number of mature Elm trees on the western boulevard of the service road which appear to represent the original American Elm planting.  The inner ring planting of elms and ash within the original triangular car park has been retained in a fragmentary form after the recent reconfiguration, represented by a small number of Elm trees located on the perimeter of the paved area and in island beds within it.  Some of these trees are certainly later replacement plantings some may be original American Elms.
