First Signs of Emerald Ash Borer Damage Observed at White Memorial

Emerald ash borer is a highly invasive insect that was introduced from Asia and was first detected at White Memorial in 2014.  White Memorial staff and volunteers utilized a variety of surveillance programs starting in 2012 including Cerceris wasp biosurveillance, double-decker purple prism traps, and encouraging USDA and UCONN to install canopy purple prism traps throughout the property.  We observed our first signs of Emerald Ash Borer damage on the property during the winter of 2016 and 2017.  The damage is caused by woodpeckers picking at the bark of ash trees exposing the lighter-colored underbark to acquire EAB larvae living under the bark.  This pattern is commonly referred to as "blonding".  Blonding is often observed in the canopy of the trees first since that is where the adults often lay their eggs and where the larvae start to feed under the bark.  We often see blonding along the southern aspect of the tree trunk which is likely the preferred location for adults to lay their eggs so that larvae develop faster on the warmer side of the tree.

for Emerald Ash Borer (Agrilus planipennis) larvae.
Blonding can be observed along the entire length of the tree trunk, from canopy to ground.

Waterfowl Nest Boxes Check for 2017

(l to r) Jared Franklin, Rachelle Talbot, and Ireland Kennedy check waterfowl nest boxes
 to monitor seasonal productivity and maintenance needs.
White Memorial checks waterfowl nest boxes annually to monitor the breeding productivity of wood duck and hooded mergansers on the property.  Waterfowl populations have rebounded since the early 20th century due to increasing nest sites by installing nest boxes, protecting wetland habitats, and regulating harvesting by creating and enforcing wildlife conservation laws.  Waterfowl nest boxes are installed in or very close to wetland habitats on the Foundation property and are used briefly by the ducks for laying and incubating eggs.  Ducks and mergansers hatch fully feathered with their eyes open and vacate the boxes very soon after they hatch.  White Memorial has a total of 28 nest boxes on the property, of which we were able to safely check 27 boxes.  A total of 20 boxes were used by waterfowl which were able to fledge a total of 102 chicks.  Wood shavings are used as nesting materials and are replaced each year.

Wildlife Camera Images -- January 2017

I have set several remotely triggered wildlife cameras along trails and near feeders to record wildlife.  Wildlife cameras have become an important tool for assessing population abundance, habitat associations, and other ecological questions for a variety of wildlife organisms.  White Memorial can use this information as an additional source of species inventory data and I'll periodically post images of wildlife captured using this technology.
