Abstract:
The typical home lawn is an evolving ecosystem that gets more complex each year.
At first, it consists of one or two grass species found in a typical seed mix (e.g., Kentucky
bluegrass and perennial ryegrass). Over time, it evolves to three or four species
that were not part of the original seed mix but are well adapted to western Oregon’s
environment. This mix of new species is referred to as a “climax lawn.” Climax lawns
generally consist of bentgrasses (highland, colonial, and creeping) and bluegrasses
(annual and roughstalk). The conversion to a climax lawn is a natural process, and the
end result is a lawn adapted to your growing environment.
