Landscape maintenance Revised Exam study Guide.

Landscape maintenance Revised Exam study Guide. Landscapes require maintenance, because they — like any natural system — are always in flux. Plants grow, soils change, erosion happens, leaves fall and weeds grow. Many common forms of maintenance are incredibly harmful to the environment. Maintenance activities can release unnecessary chemicals into the environment, contaminate water, pollute the air and impact human health. Sustainable maintenance practices, on the other hand, work with the environment to achieve aesthetic and environmental benefits. Thoughtful, sustainable maintenance is key to the success of a landscape. This means working with nature to support and nurture the living systems that make up our gardens and striving to diminish negative impacts by reducing water consumption, reusing or recycling waste, protecting air and water quality, and minimizing the use of fossil fuels. As stewards of our landscapes, we can make meaningful impacts that enhance the beauty of our garden and its ability to provide ecosystem services. The role of maintenance in a sustainable landscape The appearance of a landscape is often a key driver for maintenance; however, care of your garden can have many impacts beyond aesthetics. When thinking about sustainable maintenance, it is important to remember the interdependency between the environment, human health and the economy. The economic benefits associated with landscape maintenance are most easily found when materials or maintenance hours are reduced. All too often, maintenance practices do not reflect the needs of the landscape, but rather a set schedule that is determined by seasons or habit. This results in the unnecessary use of materials and person-hours. Sustainable landscape maintenance considers both the short- and long-term goals of a garden and is informed by careful observations and monitoring of garden conditions. Unsustainable landscapes • Use over-the-counter fertilizers, herbicides and pesticides that can have negative impacts on the health and well-being of people and the larger natural world on which we depend. • Pollute water when chemicals used in maintenance contaminate streams and aquifers. • Depend on the regular use of mechanical lawn and garden equipment that emit considerable amounts of carbon monoxide, volatile organic compounds and nitrogen oxides, increasing air pollution. Sustainable landscapes • Reduce the release of chemicals into our environment by using organic fertilizers such as compost and implementing pest management strategies that minimize hazards to people, property and the environment. • Limit the use of materials that can introduce pollutants into our waterways and also manage storm water so that it can be cleansed and reused on-site. • Reduce air and sound pollution by limiting the use of gas-powered lawnmowers, leaf lowers and similar equipment. There is a lot that goes into maintaining a landscape. Even if you’re just trying to keep up with the bare minimum, it can be a lot of work. That’s because landscapes are not self sustaining. And because they’re always evolving and growing, there are always tasks that need to be done.
