    I'm guessing that those 3.5 billion OH as trees include saplings and perhaps seedlings, while the 3.5 billion chestnuts were larger trees.  I've read that one in four trees in the eastern hardwood forest was a chestnut, and given the way trees/forests were measured 100+ years ago, those were all tall overstory trees.  However, the "not just species, but genus" points to another huge impact on forests.  Other species will fill in the gaps, as oaks (mostly) did after chestnut blight, but the forest will not be the same.

    EAB has been detected in Maine, not adjacent to its establishment in NH but in Madawaska.  The bug had been found across the St. John in Edmundston, NB a year or two before, probably transported from farther west in firewood or pallets.  That far north the native woods have just brown ash, found mainly in swampy ground and not at all abundant, which might limit the rate of advance. 

    Interesting article on evasive insects.

     

    For Vermont, in particular, the prospect of an alien invasion by the Asian longhorned beetle has horror-movie undertones. It is not because the larvae eat trees from the inside out, or that they feed on 13 species of hardwoods — all of which can be found in state’s hardwood forests.

    It is that their preferred species are maple: Norway, red and sugar.

    The scenario this conjures — the possible cost to the state’s economy, the mega-million dollar maple industry, tourism, the very image of Vermont — imagine an autumn color palette minus all the reds — is incalculable and unimaginable, so most people prefer not to.

    “The potential impact on Vermont — the loss of maple. It would be … ” Meredith Whitney, the UVM extension service’s forest pest education coordinator, pauses to search for the right word. “Horrible.”

    The damage from the emerald ash borer in CT is alarming. I drive all over the state for my job and just about every ash tree is pretty much completely dead. I didnt realize that billions of them are going to be wiped our. They are now listed 1 step above being extinct as critically endangered. I also read they are now detected in  Northern VT so all of northern new englands ash trees are pretty much doomed.

    I have been treating my ash trees with insectside to some sucess. I only have about a 20 percent canopy loss but all the other ash in my area are completely bare. 

     

    North America the emerald ash borer is an invasive species, highly destructive to ash trees in its introduced range. The damage of this insect rivals that of Chestnut blight and Dutch Elm Disease.[17] To put its damage in perspective, the number of chestnuts killed by the Chestnut blight was around 3.5 billion chestnut trees while there are 3.5 billion ash trees in Ohio alone. Dutch Elm Disease killed only 200 million elm trees while EAB threatens 7.5 billion ash trees in the United States. The insect threatens the entire North American genus Fraxinus, while past invasive tree pests have only threatened a single species within a genus.

    Just got a ton of reports from friends//family of some good sightings of the Orionid Meteors tonight along the CT shoreline.

    One of the year's best sky shows will peak this weekend between Oct. 20 and 22, when the Orionid meteor shower reaches its best viewing. The meteors that streak across the sky are some of the fastest and brightest among meteor showers, because the Earth is hitting a stream of particles almost head on.

    If the rest of this summer is any indication we will probably be screwed by clouds here but I have my fingers crossed. it will be a race against time tomorrow night with the next approaching system. 

    I lived in South Hero for a few years. The causeway is a good spot for viewing. Saw the lights a few times from there. Awesome wide open view looking north.

    TORCH!!

    Enjoy! 

    With the persistent SW flow, dewpts will continue to slowly rise
overnight, up to the upper 50s to lower 60s by around daybreak.

The Bermuda high takes up residence along the mid Atlc and SE
U.S. coast, setting up for our first day of hazy, hot and humid
weather across the region.

    NWS Boston bumped it to 90.

      

    
Thursday...

A mid summer-like day appears to be in the cards for much of the
region. A very mild start with 850T around +16C coupled with
southwest flow should yield a very warm to hot afternoon. High
temperatures will likely reach near 90 away from a modified marine
airmass across portions of RI/SE MA and especially the Cape/Islands.
Dry weather will dominate Thu as forcing will be limited, but can
not rule out the low risk for a few afternoon/evening T-storms on
a pre-frontal trough.
