Lighting Up the Landscape Lighting Effects in Water Features © Elite Landscape Lights O ff-season lighting can create a total shift in dynamic comparative to spring and summer, especially with variations in colour contrast. Specific types of lighting¹ can enhance the aesthetic and functionality of landscape design and can be revised to compliment the atmosphere or mood of a season. In particular, night lighting in the landscape is especially important in the autumn and winter months when daylight hours slowly recede into quiet solitude. In Lighting Up the Landscape , we will explore the basics of lighting effects on softscaping and hardscaping design elements. Lighting can optimize the aesthetic and functionality of water features through the exploitation of two main behaviours characteristic of water, reflection and refraction . Reflection is the abrupt change in the direction of wave propagules that strike the boundary between two different media, where at least

The Invaders How to Recognize and Report Invasive Species © Alberta Agriculture and Forestry What is an Invasive Species? An invasive species is an organism that has been introduced into an area beyond its original geographic range and has the potential to cause severe consequences to the economic, ecological and social sustainability of an ecosystem. What are Invasive Species a Problem? Invasive species are a major problem as they ultimately transform the character, condition, form or nature of ecosystems over a substantial area. In North America, 20–30% of introduced species inflict serious environmental damage, reducing the population of endangered native plants by 42% and causing $138,000,000,000 in deficits per year. Invasive plant species have been difficult to control and nearly impossible to eradicate since their introduction into our ecosystems. What are Some Examples of Invasive Specie

Xeriscaping A Guide to Water Conservation in Landscapes What is Xeriscaping? Xeriscaping is defined as a style of landscaping or gardening that promotes the ecological conservation of natural resources through water-smart design principles. Xeriscaping Benefits Xeriscaping serves a significant role in determining the environmental sustainability of a landscape and demonstrates synergetic advantages to both human and wildlife communities: Increases water conservation (50–75%).   Decreases maintenance, labour and cost. Decreases soil erosivity and erodibility. Increases soil infiltration, percolation and aeration. Minimizes or eliminates fertilizers and pesticides. Reduces carbon emissions, chemical pollution and contaminants. Provides wildlife resources for beneficial organisms. Increases property value (10–25%). Xeriscape Design Figure 1.

Integrated Pest Management How to Create a Step-By-Step Treatment Plan for the Landscape © Purdue University What is Integrated Pest Management? Integrated Pest Management (IPM) is an ecological approach to regulating pest populations by incorporating ecological action thresholds and effective, environmentally and economically sensible methods such as preventative, cultural, mechanical, biological and chemical applications. IPM is considered to be the cornerstone for environmental stewardship because it plays a vital role in managing ecological sustainability of agricultural and urban environments. What isn’t Integrated Pest Management? Integrated Pest Management is not about the elimination of pests. An attempt to completely decimate every pathogen is unrealistic, expensive and can cause more harm to the ecology of your garden. Integrated pest management is about suppressing pest populations to a tolerable level to achieve a sense of balance in an urban ec
