The results are in, and the 2019 annual Silviculture Best Management Practices (BMP) Implementation Monitoring Report shows that the logging industry and timberland owners continue to excel at protecting Virginia’s water resources. Forests are essential to clean, healthy drinking water and watersheds, and sustainably-managed forests are the most effective land cover for protecting water quality.

We expect to see Christmas trees at Christmas tree farms, but this decorated eastern red cedar is located on the edge of a 2-year old pine plantation.
On a recent rainy day, the bald eagle below appeared to be hunting in a clearcut.
The bald eagle population has made a notable recovery since DDT was banned [Richmond Times article], and we see them quite often in the Chesapeake Bay region. With 272 breeding pairs along the James River in 2017, that eagle population appears to be reaching carrying capacity. The next time you hear that unique bird call, look up and you may see a bald eagle.
Several years ago, as I was driving along Route 30 towards West Point, I saw an eagle steal a dead opossum from a group of vultures on the side of the road. Much to my surprise, it tried to make its getaway straight towards my car. At the last minute, it dropped the opossum on the road directly in front of me in order to clear the roof of my car. I was very relieved that I did not hit the eagle or the opossum.

An SMZ or streamside management zone, also known as a riparian buffer, is an area along a stream or creek (or a river if you have one in your back yard!). In forestry this SMZ is commonly wooded (grass buffers can be very important in agriculture areas). During a timber harvest the VDOF encourages all landowners to retain at minimum 50 percent of the trees in these edges for at least 50 feet back from the water’s edge.
Retaining these trees will help to keep water temperatures cooler, reduce the amount of sediments that may enter the water and absorb nutrients that may drain toward the water. These retained forests also are used by wildlife for nesting, roosting, travel and resting to name but a few uses.
SMZs are one of the Best Management Practices (BMP) used in forestry to protect the soil and water resources on properties. In non-Chesapeake Bay localities, BMP’s like SMZs are put in place voluntarily by the landowner. In counties that are in the Chesapeake Bay Watershed, BMPs are required to comply with the Chesapeake Bay Act. Talk to your VDOF forester or consultant forester to plan your BMP implementation prior to harvest.
I was out this spring GPS measuring an SMZ for a potential Riparian Buffer Tax Credit in my work unit. The water flowing in the channel that had been buffered during a timber harvest was flowing fast and crystal clear. That got me thinking of all the “ecosystem services” that SMZs and forests provide.
You may know that forests and SMZs protect water quality by filtering sediments and nutrients that might flow overland and through the soil and into larger rivers, streams and the Chesapeake Bay. In many places in Virginia these waters flow into reservoirs that provide drinking water to our small and large communities. That in itself would make SMZs some of the most valuable forest land in Virginia.
It was nearly April and in our work area that means it is time for shad and herring to begin their “run” upstream. I happened to run into Eric Brittle, a Department of Game and Inland Fisheries fish biologist, at the recent Chowan Soil and Water Conservation District Farm Day in Southampton County. I asked him if these spawning fish would have lived in the stream that had been protected during harvest.
He explained that shad and herring spend most of their lives in the salty waters of the Chesapeake Bay and the Atlantic Ocean. In the spring of the year, adult fish return to fresh water streams to mate and lay their eggs. Shad and herring are not as common as they once were in Virginia’s waterways. Eric said that where I was in the Blackwater River watershed was probably too far upstream for them to reach.
He went on to tell me that we have another fish that most certainly does make it all the way from the Sargasso Sea in the middle of the Atlantic Ocean! American eels are spawned in the Sargasso Sea and eventually make their way back to the freshwater streams that feed the Chesapeake Bay. (An interesting side note: The Sargasso Sea is the only sea without a land boundary).
In these freshwater streams they mature and live until they return to the Sargasso Sea to spawn. An even more fantastic story is that if your watershed is connected to the Chesapeake Bay (any place east of the western edge of the Blue Ridge Mountains), it is very possible that it supports these long-range travelers.
It was not that long ago that many people that lived in Virginia could expect to perhaps never leave the Old Dominion in their lifetime. But these aquatic Virginia natives could not have survived without making journeys of thousands of miles. The next time you see a strip of trees in the middle of a harvest area, know that the landowner has contributed to the life cycle of the American eel, and perhaps even shad and herring.

An important skill for foresters is hopping across creeks without falling in, especially during cold weather. Last week, I was mapping creeks alongside a cutover to assist a landowner with a Riparian Buffer Tax Credit application. Wooded buffers along streams, rivers and the Chesapeake Bay are called riparian forests and help protect our water quality. Virginia landowners can receive a tax credit for preserving riparian forest buffers along waterways during a timber harvest operation.
Usually, creeks in the Coastal Plain have muddy bottoms, so the gravelly looking area of this creek made me stop to look closer.
The rocky looking objects are all fossils from the Yorktown Formation, which is a layer of bedrock formed during the Pliocene Epoch, 2.5 – 5 million years ago. There are two fossilized oyster shells in the lower left, and the large scallop shell above them is the Virginia state fossil, Chesapecten jeffersonius. In the center is a clump of fossilized barnacles. There are several other familiar shell shapes as you examine the photo more closely.
Creeks and riverbanks in the Coastal Plain can reveal these fossils as water cuts through the exposed outcrops of the Yorktown Formation. This creek was part of the ocean bed 4 million years ago, but it is 45 miles away from the edge of the Atlantic Ocean today.
