Fall is a prime time for planting trees, and Delaware Nature Society has planted quite a few in the last three weeks. Planting trees in the fall can be the best time because the trees are going dormant for the winter and the ground is often very moist, which means when spring comes and the soil starts to warm, the trees will be ready to grow.

In the past several weeks, Delaware Nature Society has planted over 600 trees at three locations. On October 27 at Coverdale Farm Preserve, the planting of 12 enormous Red Oaks and Bicolor Oaks with 9 foot root balls and full canopies began. They were brought in one at a time by truck and are being placed in a section of field that is currently used for feed hay. This planting is part of Coverdale’s 10-year Master Plan. The field the trees were planted in will be turned into a grazing pasture that will house movable animal shelters. These trees were planted in a specific area in order to create a buffer for the Farm’s neighbors, and provide shade and forage for the livestock. All 12 of the trees have been put into the ground and other areas of the farm are designated for reforestation in the future. A big thank you goes to Hank Davis who not only funded the purchase of the trees, but hand selected the trees and is also funding their installation. Hank is a true champion of Coverdale Farm Preserve, and for that we are ever grateful.

Last weekend, two large tree planting events were held on Saturday morning. The first event took place at Middle Run Natural Area where approximately 150 volunteers helped to plant 400 trees. The tree planting is just one aspect of the biodiversity management project that Delaware Nature Society manages at Middle Run under contract with New Castle County. Jim White, DelNature’s Senior Fellow for Land Biodiversity Management, heads up the planting efforts each year. “We are working to increase the park’s forest habitat as well as to increase stream buffers next to Middle Run, which is a tributary of White Clay Creek,” says Jim. Increasing forest habitat provides food and shelter for a wide variety of native wildlife. Stream buffers slow down and filter pollutants and help to reduce erosion. Tree planting also has many other benefits, including making a positive impact on climate change. County Executive, Matthew Meyer also attended the event, lending a hand with the planting. Since 1991, thousands of volunteers have helped to plant about 55,000 trees at this New Castle County park, which is located near Paper Mill and Possum Park roads in Newark.

The second planting event last weekend was held at DuPont Environmental Education Center (DEEC). The Rotary Club of Wilmington planted 200 trees in the Russel Peterson Urban Wildlife Refuge with staff from the DNREC Division of Fish and Wildlife.  The project was funded by members of the Rotary Club who donated $2,000 for the trees along with funding from DNREC. The tree planting is part of an effort over the past 20 years to restore the freshwater tidal marsh with native plants to provide habitat for waterfowl, song birds, deer, raccoon, beaver, and even river otter. The Rotary Club of Wilmington planted the trees as part of a challenge to all Rotary Clubs across the globe. International Rotary President, Ian H.S. Riseley challenged every Rotary club to make a difference by planting one tree for each of its members between the start of the Rotary year on July 1, 2017 and Earth Day on April 22, 2018.

A sincere thank you to everyone who was a part of each of these events!

“I think that I shall never see, a poem lovely as a tree” (Joyce Kilmer, 1913).

Trying to identify trees is a lot of fun and can be done by anyone with both patience and a good field guide because almost all trees belonging to the same species have the same general appearance in terms of their size, bark, and leaf shape and arrangement. Still, sometimes one comes across a specimen that stands out from the others, perhaps because of its unusual appearance or location. These are my four favorite trees found on DelNature lands.

1) This massive American Sycamore is affectionately known as “Old Mr Knobbles” and is a much-visited centerpiece of the Ashland Nature Center floodplain. Although there are several huge Sycamores growing along the creek they all have a single vertical trunk whereas this specimen has two equally thick trunks, one of which seems to defy gravity by growing almost horizontally!

2) This Gray Birch stands alone in the corner of the hilltop behind Coverdale Farm. There was a pair of Gray Birches standing side by side here for many years but one was blown down by a storm in the spring of 2016, leaving this distinctively-colored tree standing forlornly against a dramatic backdrop of sweeping fields.

3) The great majority of trees have just one trunk but this monster Bitternut Hickory hidden away in the woods of Coverdale Farm Preserve has no fewer than six! Although one of the trunks is fairly small and another two are joined at the base it is still an unusual tree as the six trunks form a neat crown that supports the many branches.

4) Swamp Oak. This striking pale gray tree is tucked away in a dark corner of Burrows Run Preserve. As with White Oaks the trunk is relatively smooth near the base but begins to peel and flake further up the tree. However the peeling is so pronounced on Swamp Oaks that the bark seems to hang in sheets like plates of armor!

There are many beautiful trees scattered around our properties. Next time you walk our trails be sure to look carefully into the woods – you may find your own favorite tree!

Even though much of the snow has melted and what is left are gray and black piles in parking lots, a Wednesday walk at the Delaware Nature Society’s Flint Woods Preserve revealed the beauty of winter and a few hints at spring.

It was obvious that animals were finding food – we found evidence of eating and the eaten.  A crabapple tree had the remnants of eaten fruits and discarded seeds beneath – the birds had been busy.

At the edge of a field we found where a fox had been digging into the snow.   A fairly deep hole made us wonder if the fox had chased a rodent or maybe smelled it through the snow.  Did he catch it?  You bet.   We found the guts of the little guy close by.  Why did it leave that part behind?

We hear about squirrels burying nuts, but a pile of nut shells let us know that one squirrel had dug through the snow to find them.  Bill the Land Manager has an active bird feeder.  A Carolina Wren was sitting beneath the feeder and must have been hungry since he let us get quite close.

The sun came out and the we were struck by the beauty of the woods, even if most folks are getting sick of the white stuff.   The melting was obvious and many wet areas were exposed which held one of the first flowers of the year, a skunk cabbage, which was in bloom.

We also found a few invertebrates that were active on this winter day.  We ran into a web that had an active spider.  The spider moved onto the web when we brushed it.  We also found an insect that flew and looked like a mosquito, but turned out to be a Winter Crane Fly.  I chased it down until it landed on the snow.

The ground was so wet that several mature trees that seemed perfectly healthy had fallen over – their roots were not deep enough to hold them.  With upcoming storms and remaining winter winds, how many more might fall?  One beauty – a tuliptree (liriodendrum tulipifera) – looked stable and very grand – a giant in this forest.

With corn stubble poking through the snow, the landscape still looked in the grip of winter.  The calendar tells us that spring is less than a month away.  The changes will be coming soon….. promise!

Flint Woods bird surveys take place each Wednesday morning and are free.  If you are interested in helping, please call (302) 239-2334 ext. 115.  The preserve is closed to the public except for guided walks such as this.

Register for the Spring Migration Birding Series, which will include a visit to the Delaware Nature Society’s Flint Woods Preserve.  The series begins on March 12 and includes 6 walks in March and April.  For more information, click here.

During the past two weeks, I’ve spent a lot of time outdoors in windy, snowy, cold weather looking for birds on Christmas Bird Counts in PA, NJ, and DE.  One of the highlights was a close encounter with something “mewing” from a tree.  Was it a kitten high up in need of rescue from the local fire company?  It certainly sounded like it, but a closer look revealed a bird that does a pretty good kitten imitation.  No, it wasn’t a Catbird, but a winter resident with a strange and unusual name…the Yellow-bellied Sapsucker.

The Yellow-bellied Sapsucker is an unusual woodpecker that spends the winter in Delaware.  Unusual in that a large portion of its diet is sap from trees.  Apparently, Sapsuckers will drink the sap from over 1,000 species of woody plants, but in this area, I usually see their sapwells on maples, elms, hickories, and walnuts.  These birds get the sap by drilling into tree bark.  Sapsuckers maintain and visit their sap wells daily to eat the sap that has collected in the well and any insects that may be nearby.  The sapsucker drills a round hole to get xylem sap and a rectangular slit to get phloem sap.  In our area, I normally see the round holes used for extracting xylem sap.

Other animals utilize the wells during winter and early spring.  Squirrels, other woodpeckers, and insects like Mourning Cloak butterflies find sapsucker wells to their liking.  The Ruby-throated Hummingbird is a heavy user of sapsucker holes, especially if they find themselves in an area with little flower-bloom.  Sapsuckers will defend their sap wells from these nectar-stealers.

The Yellow-bellied Sapsucker blends in very well against treebark as it visits its sap wells.

Next time you hear what sounds like something “mewing” up in a tree, don’t rush for the phone to dial the fire department.  Take a closer look…it might be a Yellow-bellied Sapsucker.  Also, look for Sapsucker holes near where you live.  See if this woodpecker with the strange name pays a visit during the winter. 

Sign up for the Breakfast and Birds at Coverdale Farm taking place on Friday, January 15.  Enjoy a delicious and healthy breakfast including Coverdale Farm chicken eggs, and a walk around the farm and Burrows Run Preserve to find wintering species, and maybe, a Yellow-bellied Sapsucker.
