[MAIPC] Native meadows

Thu May 28 05:22:30 PDT 2015

I read a study a decade ago that the when the non-native lambs quarters met the native in our region many, many years ago, they got mixed together, and even hybridized, and it is difficult to tell if a specific specimen is the native or introduced. The general advice was to consider it native. Marc

A plant that can be both native and introduced at the same time is truly special. I'd say the plant is easier to ingest than the concept.

Some folks consider lambs quarters native even if global.

In several instances--not on meadow restorations--I've observed that lambs quarters can grow very densely the first year after soil is disturbed, then largely disappear in subsequent years without any efforts to discourage it. Can't say whether any other weedy species have that deceptive first year surge.

Hi everyone,

I am in the process of converting some fescue pastures to native wildflower/grass meadows. I use glyphosate to kill off each pasture 3 times (spring-autumn-spring) then seed it. I understand that flushes of dormant weeds (foxtail, oxeye daisy) are common during the meadow establishment. 

Biennial thistles (e.g. bull thistle) are showing up in amazing numbers following our 1st seeding. Should I devote as much energy as possible to killing thistles in our native meadows or will they decrease once the native plants get established?

Thanks to everyone who uses & contributes to this mailing list!
