[Carpenter] Burr oak savanna

[Kevin Carpenter]

Thanks John -

I guess my idea of a burr oak savanna (and I love the look of burr oaks!),
is about 20% mature tree coverage, perhaps less - lots of sun between the
trees, but enough trees that its obviously "wooded".  With this comes
sufficient spacing between the trees to allow them to spread out into
their full glory.

Field 1 was hayed this year, field 5 is booked to be burned this coming
spring.  We will check out both later this week and try and visualize
them.  Eventually we are thinking of dropping a small lake in between
fields 3 & 4 - perhaps the savanna would look nice surrounding that.

In any case, field 2 will remain tree free for our feathered friends!

Thanks again,

Kevin
