[APWG] 100 qacres every 15 miles across the country-- preserve the original ecosystems?

[Marc Imlay]

The areas need to be connected for plant and animal wildlife migration, even
more so because of climate change. About half of our species are source
species and are OK in small areas. But about half are sink species and need
a way to return over time. 1,600 feet wide is an ideal width for effective
corridors.

Certainly an interesting idea.  Attention should be paid to minimum
meaningful contiguous area for conservation purposes for various organism
types.  I fear that even if we could keep these areas 95 (or even 100)
percent weed-free, disjunct areas as small as 100 acres would be useless for
the preservation of many species.  (There is research that addresses these
issues [although I'm not sure of its adequacy].)

I agree. These areas will serve as preserves until such time as
native, or host specific non-native, biological controls are avaiable.
They should be at least 95% weed free. Marc

Dear Marc and All,

I am proposing that in the USA, we preserve 100 acres every 15 miles
in each direction, which would be a 1:1400 ratio in exchange for the
land we use for our purposes?
And that would help preserve insitu the native plant and animal
diversity we have across the nation.  And perhaps these preserves
should be owned by the local indigenous peoples?

Plus these areas could possibly be used as carbon sinks for our fossil
fuel and coal burning, to help sequester some of the carbon that we
are puitting into the air?  And that those area be restored to 99%
weed-freeness?


Sincerely,  Craig Dremann (650) 325-7333
