OP-9: Landscape Management

Exclusions: - Agricultural experimental land (including land for food production to support research animals) - Building footprints - Areas maintained by other parties (e.g. hospital, transit) - Natural woodlands

Buildings, Grounds, and Environmental Services (BGES) maintains the majority of the university's managed lands. Their IPM practices are outlined in the attached document. The University of Alberta Botanic Garden manages their own landscaping (22.4 Hectares of managed grounds). Although not formally documented, they follow an IPM plan and use herbicides only for identified noxious weeds.

BUILDINGS, GROUNDS, & ENVIRONMENTAL SERVICES (BGES) During new construction projects, landscape renovation and restoration initiatives, Buildings, Grounds & Environmental Services always seeks opportunities to incorporate native and drought-tolerant plant species. The objective is to reduce irrigation demands and to select plants which more readily adapt to Edmonton's climatic conditions. To this end, landscape architects are encouraged to consider native plants – both shrubs and grasses. The use of grass as a ground cover is discouraged and used only in gathering spaces such as the quads. The university is also moving towards using more perennial plants when possible. UNIVERSITY OF ALBERTA BOTANIC GARDEN Plant stewardship initiatives include: - accessioned plant collections - in-situ and ex-situ conservation specimens - garden landscape integrated into natural forest and wetlands

BUILDINGS, GROUNDS & ENVIRONMENTAL SERVICES (BGES) The university actively looks for ways to incorporate water capture and reuse into landscape management plans and practices. Several examples of water capture for irrigation are highlighted in OP-22 Water Use. Additionally, the university's xeriscaping principles are outlined below. The principles of xeriscaping are considered and incorporated into all landscape design initiatives, whether in landscape rejuvenation or in new capital projects. The underlying objective is to reduce dependency of all plant materials—whether trees, shrubs, perennials, annuals or turf grass—on potable water. The following practices of xeriscape landscape design and maintenance are part of the Buildings, Grounds & Environmental Services maintenance philosophy: - Where feasible, design for water conservation and water harvesting by directing rain water and surface run-off to planting beds. - Design groups of plants rather than single plants with similar water needs. - Amend soil to improve nutrient availability and water retention capacities; this provides for healthier plants that can survive with less frequent watering. - Schedule lawn irrigation to provide water at optimum times of the day, and in optimum quantities, such that water is not wasted and plants do not become dependent on too much moisture. - Increase mowing heights to three inches to decrease evaporation of moisture, encourage deeper plant roots, and promote more vigorous, weed-resistant growth. - Explore the extensive selection of drought tolerant plant materials available for prairie climates and incorporate them into campus landscapes. - Place organic mulch on all soil surfaces in shrub beds, borders and tree wells to conserve water. Examples of landscape construction projects that incorporated xeriscaping principles include: - Triffo Hall - Centennial Centre for Interdisciplinary Science - Edmonton Clinic Health Academy - East Campus Village - Graduate Student Housing - East Campus Village Phase II - Pinecrest and Tamarack Houses - Cooling Plant on Campus - Physical Activity and Wellness Centre - Founders Hall - Jeanne and Peter Lougheed Performing Arts Centre - Donadeo Innovation Centre for Engineering - Peter Lougheed Hall - Nîpisîy House - Research and Collections Resource Facility UNIVERSITY OF ALBERTA BOTANIC GARDEN Hydrology and water use initiatives approach includes: - on-site wells that provide water for irrigation and display fountain systems - potable water is only used in buildings - hydrology of the site is governed by natural wetlands - buffer zones, slow ditches and riparian areas help to manage groundwater runoff - display and interpretive beds - plantings of xeriscaping

BUILDINGS, GROUNDS & ENVIRONMENTAL SERVICES (BGES) All mowers have a mulch kit to grass-cycle trimmings. Yard waste is managed in a number of ways: - tree pruning contractors create mulch from pruned branches for use in university beds - some yard waste is collected and sent to City of Edmonton facilities to be turned into mulch and used by the City Compost is utilized as follows: - in some years, compost has been purchased from the company receiving the university's organic waste for use in university beds - compost from the university's dairy farms has been used for some landscape management activities UNIVERSITY OF ALBERTA BOTANIC GARDEN Materials management and waste minimization initiatives include: - exclusive use of mulch mowers - all materials removed from landscape are recycled into mulch or compost with the exception diseased material or those with insect issues

The University of Alberta's Edmonton Clinic Health Academy has two green roofs, which help to regulate the temperature of the building, improving its overall efficiency. At the University of Alberta Botanic Garden, the entrance building has a green wall screening to control temperature in front of exterior wall glazing (windows). In addition, the overall landscape theme is a garden within a forest, allowing the forest to create wind breaks and shading to both the garden areas and buildings.

According to the Canadian Climate Normals 1981-2010 Station Data (available: https://climate.weather.gc.ca/climate_normals/), Edmonton receives an average of 123.5 cm of snowfall annually, over a possible 9 months of the year (Sept to May). By comparison, Vancouver receives an average snowfall of 38.1 cm over a possible 7 months and Toronto receives an average of 121.5 cm over a possible 7 months. Thus, snow and ice removal practices are an important part of our operations and maintenance strategy. BUILDINGS, GROUNDS & ENVIRONMENTAL SERVICES (BGES) A number of steps have been taken to ensure the safety of the university community while minimizing any negative impact on the landscape. Steps include: • Using a rock chip that requires only a small percentage of salt content to keep the material usable, even in Alberta’s coldest winter months. • Using controllable boxes to control the rate of spread of ice melt products. • Only using ice melt products when snow and ice are present, not in anticipation of ice or snow. • Training staff in the proper use of the ice melt product. Other sustainable landscape management practices used by BGES include: - using electric snow and leaf blowers when conditions allow - purchasing new equipment such as trucks, loaders and gators that use diesel exhaust fluid (DEF), which reduces the amount of air pollution created by a diesel engine AUGUSTANA CAMPUS Augustana Campus has implemented a snow and ice removal program that further enhances the practices already in place at other campuses. Along with standard practices consistent with those listed above, a detailed diagram of the campus has been prepared to assist equipment operators in ploughing and storing snow in such a way as to least affect grass, trees, shrubs and spring water runoff. UNIVERSITY OF ALBERTA BOTANIC GARDEN Other sustainable landscape management practices: - buffer zone maintained on perimeter of property for fire barrier - use of zero emission fuel in all cycle engines - mowers, chainsaws, blowers, trimmers etc. - use of vegetable based lubricant in equipment - chainsaws
