A Kid's Guide to
Keystone Species in Nature
A Kid’s Guide to Keystone Species in Nature focuses on
several ecosystems such as those found in grassland,
mountains, ponds, streams, and forests. Certain species of
animals and plants are so important to their ecosystems,
that if they disappear, the whole system may collapse. Th ey
are called keystone species. Today scientists are focusing
more attention on preserving the natural balance in
ecosystems. Identifying and protecting keystone species is
an important part of their work. Th ese books meet several
of the Next Generation Science Standards (NGSS) along
with Common Core Standards for grades 3, 4 and 5.
