Card Description: Trend cards represent long term weather conditions that may affect tree growth. Trends occur over the span of days to even years. Like cloud cards, trend cards can enable disasters and make habitats more or less stable. However, trend cards can also change the entire climate of a habitat. Significant weather trends can change the normal amount of moisture in the soil and the temperature of the air.
