Document Summary
The different symbols represent if it thaws early in th spring or later. The vast majority of the lakes across the country are accelerating at the date of thaw. All the aquatic animals that rely on the lake, theres a change in their habitat. Bud burst is the first sign that spring is coming, its where the leaves start to appear on the branches of trees. A lot of the colours are yellow/orange, which is not much change in days over the years. Most of the area is red, whch means leafing is happening 1-2 days earlier per year. This study was over 46 years of measuring the date of first floweing. 54-90s, but the vast majority of species are flowering earlier, and this is 2-4 weeks ealier than in the. This tells us that spring is coming sooner. Catarpillar which fed on the oaks reach their peak abundance and its coming earlier as the budburst in oask happens earlier.
