Subject: Re: [NatureNS] Hemlock Woolly Adelgid Meeting
=20
Condolences, John. Hemlock is one of our most beautiful shade tolerant =
long lived trees and it sets the structure of many ravines, riparian =
forests and old growths.=20
I'd advise caution, however In adopting either a sanitary, a chemical or =
a treatment that uses non native biocontrols.
Wild forest management is the proper job of a forest ecologist who sees =
structure, forest successional dynamics and evolution. The sky is not =
falling; as I've pointed out, other areas have gone through this and =
forests change and in some (many if we read the West Virginia phd) =
affected forests, hemlock persists and relinquishes some of its =
dominance to cherry birch, the species determined by availability in the =
area. Here it will probably be yellow birch and red spruce but we will =
see.
=20
Active management makes humans and particularly those in mandated =
organizations feel they are not being negligent ..due diligence =
etc...but forests change and we would do best for nature to let it =
change and only intervene where we think there are regeneration issues. =
It's a good time to collect tree seeds, start nursery stock of yellow =
birch and red spruce hobble bush mountain maple.
=20
The public has lost its forest commons as we cede the forest to =
companies that clearcut. If we care about forests and nature, let the =
forests be wild...connect up wild areas onto corridors...but don't treat =
wild forest like gardens or we will be mimicking the clear cutting =
mentality at work on most of our forest commons.=20
=20
Let's have some faith in nature and not think it's helpless without us. =
Holding back and not rushing to active management will be hard for =
people in government and conservation organizations but succession can =
handle what we think is a crisis. How it handles it is the beauty and =
wisdom of nature.
=20
I haven't got into carbon implications but obviously the less we do and =
the more we let succession regenerate a fast growth of new trees to mop =
up mineralized nutrients, tie up more carbon all amid the existing =
carbon in the old hemlock, the more we are doing our part for slowing =
climate change...the more we remove and hack and burn...
=20
Lastly, we are in, undeniably, a time of vegetation change brought n by =
climate change. Such forest changes will be opportunities for =
biodiversity and we will witness exciting positive changes.

Hi All,
Our hemlock trees are in serious trouble. The culprit is an aphid =

The Tusket River Environmental Protection Association (TREPA) will be =

Canadian Food Inspection Agency, at the Yarmouth County Museum and =
Archives, 22 Collins Street, Yarmouth, on Tuesday, April 10th, at 7:00 =
PM. All are welcome.
