To the Editor:

Native and introduced plants both contribute greatly to our lives and localities.

The state recognizes more than 30 invasive -- self-spreading, native-plant displacing -- species.

Being rapidly lost are irreplaceable indigenous seed varieties which developed over millennia to local conditions and provide diversity necessary to life-sustaining ecosystems.

Dwindling are natural bounties of roadsides, fields, deep forests, hills, and watersides, most noticeably wild flowers and wild berries.

With current responses, in a few years, this conflict will be over -- irretrievably lost.

Unreliably promoted as non-spreading, many ornamentals do and have spread often unnoticed into conducive habitats.

Many exotic ornamentals are highly valued, sprouting seasonally-colorful flowers or leaves earlier and lasting later than native plants.

Forsythia yellows have become a herald of spring.

Burning Bush (Euonymus Alatus) reds last past the colorful native maples.

Early blooming/later lasting leaves impart a longer growing season advantage, competing for limited resources with native -- especially vulnerable, endemic, annual and perennial plants.

Invasives may stand out clearly in this fall season, providing opportunities to most easily identify and remove.

Maples green-leafed still are probably naturalizing non-native Norway maple and should likely be removed.

Vines with beautiful orange-looking berries, red berry/yellow casings are probably not the uncommon native species but invasive Bittersweet, now yellow leaved, that forms a ground-level, native dead-zone near monoculture, while vertically out-competing vines such as native grapes.

Coordination is needed with neighbors and landscapers of private, public, small, large, farm, and forest lands to prevent each property from becoming or expanding as a vector for the quiet rapid spread of displacers up to six feet per year vertically, horizontally, and below ground.

Opportunities to remove easily are lost once roots get established.

Every season counts.
