Back in 2012 we began with a small germ of a proposal to take the Peck/Callahan Preserve, a mature forest area with diminished benefit to wildlife, and create a new habitat, one that is scarce in Connecticut-a young forest.
These early stage landscapes are rare in Connecticut for many reasons. Farms that were abandoned grew into to young forests at first, but have now aged via the process of normal succession into more mature woodlands. Fires and other natural disasters have often been managed, so widespread forest destruction is rare. And, where woodlands are cut, it is often for development and the landscape becomes fragmented with suburban accessories such as homes, yards and roads. None of these support the wildlife that needs thick dense low-growing vegetation. There are approximately 50 species in Connecticut that rely on this type of habitat. The best example was the New England Cottontail that was one the edge of becoming endangered in our state.
So Avalonia embarked on an ambitious project, with guidance from USFWS and DEEP and large grants. Approximately 28 acres of older growth forest were cut leaving some tall trees to provide shelter and seed sources. It was a pretty barren and bleak landscape when the project was completed. There was very little greenery at the end of the cutting. There was woody debris laid on the ground. This is known as slash, and it provides soil nutrients as it decays. We also created dozens of brush piles with some of the debris, which provide immediate shelter for all kinds of wildlife.

We monitored the area yearly. You can read about our progress here.
Now fast forward to this summer. The young forest is developing beautifully. At age 5, it is prime habitat for providing dense cover for many species. There are no barren spots or unproductive openings. The vegetation is varied and includes small trees as well as vines and shrubs bearing fruits and many berries. The berries are favored by birds and mammals. Smaller flowering plants have popped up in the sunny openings providing nectar sources for all sorts of insects. The insects in turn attract more birds of various species. The only downside to all this wonderful growth, is that it is now impossible to walk through it at all. We used to be able to wander through the entire 28 acres with little difficulty. Now it is grown and tangled and dense-bad for people, but perfect for New England Cottontails and their friends.
In July, a team went into the area to assess the growth. One Avalonia member, brought his drone and we were accompanied by DEEP biologists who have followed this project from the beginning. We launched the drone and kept an eye on the video screen, and it flew in a zig zag pattern across the landscape and also followed the boundaries to places we could not get into. What we saw and photographed was pretty amazing.

A burst of green
The entire project area was covered in green. From low growth ferns, the height rose to Low Bush Blueberries and Huckleberries loaded with fruits. Great for birds and small mammals, even Box Turtles . There were many mid-height shrubs and lots of vines. There were viburnum, more blueberries, wild grapes, blackberries with crazy thorns, and green brier with more thorns, all providing great hiding places and food as well. The cut trees had sprouted new growth, and many of them had new stems over our heads. There were also saplings of a wide variety of trees, from baby Oaks and maples and hickory and sassafras and many young tulip trees descended from the one beautiful tall one we left standing.
The brush piles were nearly obscured by greenery too. Perfect cover and homes. The biologists were thrilled with the growth. The drone was able to cover areas we couldn’t get to by foot and, we could pick out individual areas that we wanted to observe more closely. The photography was great.
While we stood and monitored the drone flight, we were so pleased to see a large number of dragonflies and other insects which attracted a number of birds. We watched tree and barn swallows, as well as chimney swifts and phoebes and peewees in flight catching their food. Indigo buntings and towhees sang from low shrubs. Bluebirds and gold finches also were heard as well as some of the other species we look and listen for along powerline cuts, and they can now spread into our young forest.
This report could go on enthusiastically for many more pages. It was gratifying to see the results. It was a hard decision early on, to do this kind of project, but seeing the vast new diversity was heartening. We were excited to use the drone as a new tool for monitoring difficult properties, and I know we will go back each year to compare.
The one thing we did not see was a New England Cottontail. But we did see signs that rabbits had nibbled several twigs and shrubs. Hopefully they are hiding in the brush piles.
