Acquisitions for the Landscape Arboretum at Winona State University Procedure

Purpose:

This procedure provides guidance to ’the Winona State University (WSU) Landscape Arboretum Director, the All-University Arboretum and Land Stewardship Committee, its sub-committees, landscape services staff, and the administration in selecting and installing tree, shrub and plant materials, exterior physical objects and landscape features on the campus grounds.

Procedure:

The Landscape Arboretum Director acts on recommendations from the Committee and its subcommittees in installing plant materials and/or physical objects or features. The Committee approves funding of acquisitions using University Foundation endowment accounts and consults with the Landscape Arboretum Director on the annual budget. The University Foundation accepts monetary donations to the Arboretum’s endowment accounts which are used to directly purchase plant materials as approved by the Committee.

A. Acquisition Criteria

Acquisitions must meet one of more of the following criteria:

1. The species is needed to complete or supplement the Minnesota Native Trees Collection.

2. The species or cultivar lends itself to a specific placement in a landscape design.

3. The species is a replacement for plant materials lost to disease, age, damage, or construction.

4. The species is not considered invasive in Minnesota.

5. The species needs testing as a replacement for other species which are no longer viable in Minnesota.

6. The species is a cultivar that needs testing as a substitute for other species which are affected by disease (ex. Dutch Elm disease, powdery mildew) or insects (ex. Emerald Ash Borer, Japanese beetles).

7. The species has value for a specific educational purpose.
