We were out for a walk in the Peggy's Cove area (the hills on the opposite
side of the road, up from the parking lot where the skating rink is to be
built). A large stand of pines there are dead, but there is some
appparently healthy new growth.

Subject: [NatureNS] Jack Pine Die-back ???
Two days ago, while traversing the proposed Five Bridge Lakes
Wilderness Area of the Chebucto Peninsula (HRM) by canoe, I noticed a large
number of dead Jack Pines in the barrens and semi-barrens near Upper Five
Bridge Lake. The dead trees show no signs of porcupine or any other damage,
remain upright, and may have died a few years ago. All other tree species in
the area (Tamarack, two spruce species, Paper Birch) appear to be healthy.
The dead Jack Pines are too high above the lake to have been negatively
effected by a slight rise in the lake's level due to a new beaver dam at its
outlet. They are solitary trees or in small clusters, and not part of a
canopy, so it doesn't seem likely that they are being outcompeted by other
tree species as part of a natural ecological succession.
Any other sightings of clusters of dead Jack Pines in the area? In the
province? Any speculation on what may be happening here?
