The winter of 2014-2015 was tough on hemlock woolly adelgid; 97 to 99 percent of the sistens, or winter, generation died.  The previous winter had similar winter mortality rates.  This helped to give hemlock trees a bit of a reprieve.  But, while these recent mortality rates have been high enough to temporarily stop the spread of HWA, the trees are still...

Vic Bogosian has an 18,000-strong army--or, rather, air-force--of wasps, and he's looking for more draftees.

"STERLING - There is a swath of grass cut on the edge of a field at Michael Pineo's farm about one-and-a-half highway lanes wide, but even that does not protect the field from one of Central Massachusetts' most challenging invaders.

"The tiny seedling was brought over from Eastern Europe and parts of Asia nearly 200 years ago and planted along riverbanks across the United States, mostly in the Southwest, to prevent erosion. It grew fast, its thick branches and oily leaves spreading across five states. As years passed, it became obvious that the introduction of salt cedar, or Tamarisk trees was a mistake.
