Small Mammal Inventory -- Little Pond -- Swamp White Oak/Basswood Stand

Juan Sanchez measures the hind foot of a white-footed mouse.

The animal was released after measurements were recorded.
If high speed indicates alertness and health, then this animal was very alert and healthy!  
We continued our inventory of small mammal species associated with various critical habitats.  This week we surveyed a unique stand of Swamp White Oak/American Basswood/Red Maple that has Carex tussocks and Skunk Cabbage in the understory and was densely colonized by the invasive Morrow's Honeysuckle bushes located near the Little Pond Boardwalk.  Although this area had muddy soils and would normally have been flooded with  knee-deep water, this area had very little water due to our dry spring season.  We have only captured White-footed Mice in this location.  All of the mice exhibited signs that they were reproductively active.  We will try to return to this site in the future to see if other small mammal species can be captured.  As the warm season progresses this area is usually very dense with ferns and other wetland associated species.

Portable Sawmill Mills WMF Trees into Wood Products

Trees harvested from the property are used to make picnic tables and
various other wood features that we use around the property. 

A portable sawmill is hired to mill the wood.
Lumber is stacked and dried for future use. 
We are proud that White Memorial Foundation is a working forest.  The trees are not only a key feature of the forest that is valued for wildlife habitat and aesthetic beauty, but the trees produce wood products that are used for a variety of purposes on the property.  Most of the wood that is harvested from the property is sold to local mills and firewood dealers, but a small amount is used here for the program's functions.  A local sawyer who operates a portable sawmill mills lumber for White Memorial every few years.  Oak, pine, and black locust are the species that are most used for constructing picnic tables and other products. 

Native Bee Monitoring -- Season's First Trap Check

Nicole Morin strains and refills the multi-colored bowl traps used to capture native bees. 

Bees and other insects captured in bowl traps are strained
and stored in plastic bags with tags until they can be identified later.
Although it is mid-March, we captured lots of invertebrates in the bowl traps.
We checked the Native Bee Monitoring Traps for the first time this season.  We captured few animals that were easily recognizable as bee species but many of the other insects will have to be left for the experts at Connecticut Agricultural Experiment Station to key out.  Tracy Zarrillo and Kimberly Stoner are leading this project for this state.  We are on our way to inventorying and establishing a base-line for long term monitoring for this vital group of organisms for the property.  If you are interested in helping with this project please notify James Fischer, WMCC Research Director.

White Memorial's Notable Trees

Of the 2.5 million trees that can be found living on the White Memorial Foundation, there are a few that stand out above the rest.  A systematic and repeatable method has been developed to measure and rate whether certain trees of the same species can be classified as a Notable Tree.  

(l to r) Eddie Matthews, Lukas Hyder, and Nicole Morin measure the spread of this tree's canopy.  
Lukas Hyder, Assistant Property Superintendent, has been reviewing the trees found on the property.  Eddie Matthews, Wamogo Region #6 H.S. Agricultural Science Education student, has been helping him with this procedure.   White Memorial conserves several trees that are recognized as some of the largest trees for certain species in the state and New England!

The circumference of the tree bole at a specific height up the trunk is measured.  


The height of the tree is measured using a clinometer at a specified distance from the tree.

The tree is geo-referenced so that it can be mapped and found later.

The tree is tagged so that everyone knows the tree is part of the project.

The data is recorded and a score is calculated.

Finally, a photo is taken of the tree with a person in the picture
to serve as a scale to size the tree


Monthly Volunteer Meeting -- March 2012


Timberdoodle Evening Air Show


We were treated to an airshow at our Monthly Volunteer Meeting.  American Woodcock were performing their springtime ritual in hopes of attracting a mate in the Saw Mill Field.  Nearby we also heard several Northern Leopard Frogs calling in the North Shore Marsh vicinity of Bantam Lake and River.  A real treat for our volunteers, who well deserve it to say the least!

We raised our Purple Martin next box in hopes that scouts returning to North America will explore it and eventually colonize it as a breeding colony.  We added red tape to the roof line to help the birds detect it from above.  The box will be monitored weekly by volunteers.  Geoff Krukar, CT DEEP Wildlife Division Avian Technician, is coordinating this program in the state and notified us that scouts have been reported as far north as New Jersey.

Native Bee Monitoring Initiated

Tracy Zarrillo (CT Ag. Exp. Station) and Jared Franklin
install traps to inventory and monitor native bees.

Tracy Zarrillo and Dr. Kimberly Stoner (CT Agricultural Experiment Station) are monitoring native bee populations throughout the state.  Bees are a very important group of insects because of their role in native ecosystems and agriculture.  The traps used for collecting bees are quite simple but effective.  They consist of plastic cups that are painted different colors (Blue, Yellow, and White) with fluid to capture the bees that investigate the cup.  The color of the cups attract the bees.  

Bees are attracted to variety of colors, this cup is painted yellow and captures bees that investigate it .
The cups are checked weekly and the specimens are sent to CAES for identification.  This data will help us inventory the species associated that inhabit the property and monitor any changes within the population. 

Only 2 hours later, a bee was observed in a white trap!

Small Mammal Live Trapping Yields a Few Animals

A wet meadow was surveyed for small mammals last week in the Apple Hill Lower field.  A total of 28 Sherman Live Traps were set for 4 nights equaling 112 trap nights of effort.  Several species were captured but overall yields were quite low indicating that small mammal abundance might be low this spring.

Wet Meadow in Late Winter/Early Spring

Meadow Voles (Microtus pennsylvanicus) are commonly associated with Wet Meadows in Connecticut.  
This wet meadow abruptly changed into a wet shrubby herbaceous inland wetland.

Vernal Pool Monitoring Workshop

I am pleased to announce that the wood frogs are clucking!  Therefore, we need to schedule our Vernal Pool Monitoring Workshop.  The workshop will be Saturday, March 31, 2012 from 12:00 p.m. to 3:00 p.m. in the Mott-Van Winkle Classroom.  Come dressed for the weather and for walking in the water.  Bring your field guides, nets, and smiles!  See you then!

New England Cottontail Rabbit Survey

Alyce Walker and I ventured up Apple Hill to survey for cottontail rabbit spore.  We found several tracks in the recent snow and more importantly we found and collected scat.  The scat will be tested to identify which cottontail rabbit left it.  New England Cottontail rabbit is our native cottontail species in southern New England, but the Eastern Cottontail has become more widespread after it's introduction to New England.  Differentiating the species is very difficult unless you can can examine the skull.  Tissue samples can be useful for identifying the species but cottontail rabbits are difficult to capture in live traps.  Fortunately, the scat yields the kind of data we need but it has to be collected under precise conditions.  We haven't had many days with very cold temperatures (below freezing) for 36 hours or more after it last snows this season.  We had one day this season to take advantage of this season, fortunately we found one scat.  This project will continue during subsequent seasons.

Scat is collected and stored in vials with silica gel (a drying agent) until laboratory analysis.


Cottontail Rabbit Tracks in Snow.

The Last Snowfall of the Season Yields Interesting Tracks

Apple Hill was a busy place after the last snow fall.  Alyce Walker and I observed several tracks suggesting that spring was right around the corner.  The coyotes and bobcats ranged all over the hill chasing after cottontail rabbits and gray squirrels.  Striped Skunks and Eastern Chipmunk were awake from their long winter sleep to find a land covered in snow.  

A Striped Skunk (smaller tracks with claws) was being followed by a Bobcat.
