To understand a site’s growing conditions, you need to look both at its regional climate and at differences from one part of the site to another. This module moves between those scales, connecting climate zones, water cycles, and the distribution of living things with the microclimates you observe on the ground.
Begin with regional climate and biodiversity, then examine how water moves through the larger system. The microclimate readings and windbreak example apply these questions to your site, using the differences in exposure, shelter, and moisture recorded in Module 3.

Compare the climate settings discussed here before turning to the microclimates of your site. The accompanying Oregon State lesson develops the link with site analysis.
Compare the geographical patterns in this resource with the Climate Zones video and Oregon State's site-analysis lesson. Consider how climate helps shape the conditions in which different biological communities occur.
Identify the main places water is stored on Earth, then follow the connections between those stores in “The water cycle.” These resources provide the larger context for the moisture conditions you examine at your site.

Compare the climates, water systems, plantings, and management shown in these episodes. Assess which ideas could fit your own climate and which depend on different conditions.
Module 3's site observations included differences in exposure and shelter. Use those observations with the microclimate readings to compare conditions in different parts of your site. The windbreak example focuses on a planting response to wind.
For your windbreak discussion, also consider seasonal drought, excessive wetness, frost, and overheating. Use current weather-service observations and projections for your site, not the historical maps in the books as present-day forecasts. Keep tropical and arid examples as comparisons; develop your own design for its actual climate.

Mounds and hollows differ in their exposure to sunlight and in how they shed or receive water. The north- and south-facing surfaces in this forest example help explain why nearby planting spots can have different growing conditions.
Consider how you could incorporate windbreaks into your design and discuss with me.
What to prepare
Notes on how windbreaks could fit your design, considering seasonal drought, wetness, frost, and overheating.
