Phenology: ES students follow the USA National Phenology Network (USA-NPN) protocols that monitor the influence of climate on the phenology of plants, animals, and landscapes . ES classes recorded phenology associated with trembling (quaking) aspen and common dandelion. Information was collected on budburst, lraf development and flowering. ES initoally joined the USA-NPN but this membership lapsed. Their "Natures Notebook" is a valuable source of information and protocols. ES observations were taken along the escarpment between Wood Street and Main.

The USA-NPN state: "Phenology is a key component of life on earth. Many birds time their nesting so that eggs hatch when insects are available to feed nestlings. In turn, insect emergence is often synchronized with leafing out in their host plants. For many people, allergy season starts when particular flowers bloom—earlier flowering means earlier allergies. Farmers and gardeners need to know when to plant to avoid frosts, and they need to know the schedule of plant and insect development to decide when to apply fertilizers and pesticides. Many interactions in nature depend on timing. In fact, phenology affects nearly all aspects of the environment, including the abundance, distribution, and diversity of organisms, ecosystem services, food webs, and the global cycles of water and carbon.".... "Changes in phenological events like flowering and bird migrations are among the most sensitive biological responses to climate change. Across the world, many spring events are occurring earlier—and fall events are happening later—than they did in the past. However, not all species and regions are changing at the same rate, leading to mismatches. How plants and animals respond to climate can help us predict whether their populations will grow or shrink – making phenology a “leading indicator” of climate change impacts."
