Vegetation Changes as Temperature Rise
- "Wisconsin has about 2,600 species of flowering plants, conifers, ferns,
and fern relatives in the wild. Nearly 1900 of
these species are native and were here before European settlement; about
700 species are alien. Many of the aliens
are weedy species, and they spread between the mid-19th and mid-20th
centuries, aided by agriculture, logging, road
building, other activities accompanying settlement and development,
changing the botanical composition on farmland and in urban areas. Now
we are seeing another wave of change, probably resulting from warming of
"These extensive botanical records for Wisconsin leave little room for
doubt that our vegetation is changing as our
climate becomes warmer. Some people may welcome longer growing seasons,
