Shortly before the construction work started, a group of botany and geology professors made proposals to enrich the park concept, in due consideration of scientific aspects.

The affiliated formed Arboretum Kommission comprised also the landscape architects Evariste Mertens and Otto Froebel and the botany Professor Carl Schröter, who managed to communicate science and beauty in the new park.

Cleverly, they modeled the fresh lake level terrain wrested from and the park in the style of the late garden laid, and succeeded in the picturesque grouping of trees.

[1] Based on the concept of Professor Schröter, the tree collection is divided into three segments:[3] A striking solitaire is the Magnolia acuminata at the sculpture of Aphrodite (1921) by the Danish sculptor Einar Utzon-Frank towards the General-Guisan-Quai.

Just steps away, there is a beautiful example of a tree grafting; aFraxinus americana graftage based on a slower growing surface, thus the strain at the intersection is almost seamlessly thicker.

[3] The lakeward side of the easterly hill section is meant by the garden architects as an open-minded moraine, and an alpinum, a collection of mountain plants, but some years later was abandoned as one of the 'garden fashions' of the 19th century.

The total renewal of the group had the advantage that all trees have the identical starting conditions and sufficient light to flourish in a few decades to ensure original character of the arboretum.

Each year there are around 45,000 visitors, including many tourists, who get free information about some of the rarest bird species of Switzerland in eight naturally designed inn walks and three landscape-like outdoor enclosures.

Conceived by Robert Landolt, the two-piece bathing complex was built in 1959/60, since 1999 it is private-owned and provides an open lake side sauna and gastronomy which were installed in 2003/04.

[6] At the foot of the lake shore hill that elevates around 3 metres (10 ft), the Arnold Bürkli memorial honors the tireless creating engineer being the driving force behind the new quays.

The simple monument was inaugurated in 1899, five years after his death, at Bürkli's favorite place in the Arboretum, or by the words of the sculptor Richard Kissling, in the midst of his creation.
