a. Provisioning services ![Provisioning Service - Maple Syrup][1] This photo shows a "sugar shack" in the valley of the Credit River in Georgetown, ON. Maple sap is boiled-down, to 1/40th its original volume, using a wood-powered boiler, to deliver maple syrup. The sap is collected directly from the adjacent trees during a period of 2 to 3 weeks in early spring, well before the ground is warm enough for planting crops. b. Regulating services ![Regulating Service, Trees - shade, erosion control and run-off mediation][2] Deciduous trees provide regulating services in the street where I live. They provide shade from the heat of the sun in summer, while allowing essential energy to pass in the spring and winter. They also provide both erosion control and run-off mediation during intense rain-fall events. c. Habitat or Supporting services ![Fallow field - habitat][3] This image shows the natural vegetation that colonized a local field in Georgetown that is currently unused prior to development. There are nest building materials for birds, cover for small mammals, and flowers for pollinating species. d. Cultural services ![Cultural service - recreational lake][4] This image shows 3-mile lake in the Almaguin Highlands of Ontario, just after sunset. Spending time at a cottage or camp ground beside one of the hundreds of lakes in Southern Ontario is a traditional summer de-stressing activity. The lakes also provide some provisioning services, in the form of fresh water fish, but their primary role is recreational. Below is the same lake, frozen over in winter, when recreation switches to snow machines and cross-country skiing. ![Cultural services - winter][5] [1]: https://edxuploads.s3.amazonaws.com/14622096848339135.jpg [2]: https://edxuploads.s3.amazonaws.com/14622107206056792.jpg [3]: https://edxuploads.s3.amazonaws.com/146221109521772.jpg [4]: https://edxuploads.s3.amazonaws.com/14622115214056867.jpg [5]: https://edxuploads.s3.amazonaws.com/14622123783429326.png
