LONG COUNTY, Georgia—Blake McMichael stands on the boundary line between two New England Forestry forests. He points out the differences between the one on his left, a forest with wet, clay soils, and his right, a dry, sandy forest that has been managed differently in order to protect gopher tortoises and their burrows.

Preferring dry soils, gopher tortoises are what’s called a keystone species, so named because their burrows provide shelter to as many as 300 other types of creatures in the forest. Rabbits, mice, insects, birds, foxes and even snakes seek shelter in their burrows, including the federally-threatened Eastern Indigo Snake.

“By protecting burrows, we’re not only helping the gopher tortoise, but also the many other species that use its shelter,” Blake says. 

Blake, a Resource Land Manager in charge of replanting forests, has the drier, sandy forests that are inhabited by gopher tortoises planted by hand. Minimizing the use of heavy equipment helps protect gopher tortoises and their burrows. The young trees will grow among vegetation like palmetto bushes and other undergrowth gophers like to eat.

On wetter soils nearby, where gopher tortoises don’t go, he had rows plowed and mechanically planted, encouraging much faster growth rates.

Found in the Southeastern U.S., gopher tortoises are vegetarians who eat berries, grasses, mushrooms and prickly pear cacti. They’re prolific diggers, with burrows reaching depths of 9 to 23 feet deep and 3 to 52 feet long! When they reach adulthood, they’re typically 15 inches long and weigh 8-15 lbs. Their average lifespan is 80 years.

Protecting Gopher Tortoises While Planting Trees

New England Forestry has its own spatial mapping system, not unlike the GPS systems consumers use when they travel. Our system has many layers of information, including a property’s soil type, topography, what has been planted there previously, notes about any protected species on the property, and much more. All that information is available on a tablet foresters can take with them into the woods.

When Blake looks at a stand of trees in the system, he can quickly find out if it has the dry, sandy soils and higher ground that gopher tortoises prefer. If active burrows have been identified on the property previously, foresters leave “pins” on the map. These indicate the presence of gopher tortoises in that particular stand of trees.

Blake also walks through the forest to visually survey the site, checking for active burrows in the process. He looks for the characteristic oval-shaped hole in the ground with a wide, sandy collar (or apron) in front. An active burrow will have clean, smooth sand in front of it, while abandoned burrows may be overgrown. The average male tortoise may dig as many as 35 burrows in his lifetime.

Protecting Gopher Tortoises During a Timber Harvest

On the other side of our business, when forests are full grown and ready for harvest, we work with our logging contractors to protect gopher tortoises and their burrows. This may include site visits, pre-harvest meetings, flagging, and showing pictures to help them know what to look for.

If a burrow is in a location where it could be overlooked, our foresters find creative ways to ensure it’s safe. In one instance, when an active burrow was found right next to a forest road, a Georgia forester had a logger place a barrier of logs beside the burrow to ensure no one drove on top of it. In another instance, our forester directed a logging crew to cut a series of trees about 4 feet high to visually cordon off an area around a burrow.

“One of the most important things that we can do as foresters is to ensure that whoever is working on our properties can play a role in protecting the burrows while they’re on site,” Blake says.

Many Species Protected in Our Forests

Gopher tortoises are just one of a myriad of wildlife New England Forestry protects on its land. For example, throughout the U.S., we protect the American Bald Eagle and its nest. In the Pacific Northwest, we protect Northern Spotted Owls and Marbled Murrelets. We have invested tens of millions of dollars into restoring salmon habitat in Washington State alone. We protect the habitat of the Red Hills Salamander in Alabama, and the Leopard Darter Fish in Oklahoma. In New Zealand, we work with conservation agencies to protect kiwi, New Zealand Falcons, and New Zealand Sea Lions. You can learn more about the many species we protect here.

And while we’re taking special care to protect vulnerable species, our forests are providing clean air, habitats for many other creatures, and clean water while they grow. Once grown, our trees will become the raw material needed for 1000s of everyday products, and we’ll replant the site for the next generation of trees.

“We’re providing a renewable, sustainable resource that people need,” Blake says. “We want to make sure we’re leaving areas where future generations have the animals that live on the property as well as the resources provided by the property.”

HOQUIAM, Washington—A forest stream went more than a century without salmon after a road crossing was built above it. Then recently the small pipe that led the stream under the road was replaced with a bridge that allowed water to flow more freely—and suddenly the stream came to life.

A few weeks after the bridge project was finished, Matt Poppe, a New England Forestry forest engineer, pulled a team of contractors off a nearby worksite to see the impact of the bridge they built.

“This is why we’re all doing this,” he told them. “There haven’t been fish in this stream for 100 years, and here we are seeing large salmon in this stream right now.”

That was just one of the 750 upgrades New England Forestry has made to culverts and bridges on its property over the last 20 years to help address Washington’s declining salmon population. The effort is guided by Forests & Fish, one of the most comprehensive environmental laws in the U.S., which protects 60,000 miles of streams across Washington’s state and private forests. It uses the latest scientific standards to ensure the best possible habitats for salmon to live and spawn in, as well as other amphibious creatures that depend on upland streams. 

In addition to replacing insufficient culverts and bridges to improve salmon habitat, New England Forestry also improves forest roads to reduce the amount of sediment making its way into streams and, when possible, closes nonessential forest roads altogether.

Since the law passed in 1999, New England Forestry has:

• Opened 220 miles of fish habitat
• Upgraded 750 culverts and bridges
• Invested $22 million in salmon habitat restoration

The long process to get a stream’s profile just right

The process to set even one project into motion can take a full year before building the structure during the “fish window,” when upland streams are naturally slowed and work will be least likely to disturb the fish, from July 15-Sept. 30. Matt must undergo months of permitting application reviews as well as a review process with stakeholders including environmental agencies and representatives of the local Native American tribes.

Portia Leigh, an area habitat biologist for the Washington Department of Fish & Wildlife (WDFW), often previews the proposed projects and advises Matt on how to make the pass-through simulate the rest of the streambed. She sometimes advises him to leave woody debris in the streambed or to drop hay seeds for vegetation, which will slow the water flow, enhance shade, and create pools and protective areas. That gives smaller salmon places to hide, spawn and grow before they go downstream into more open waters, says Portia, shown below.

Matt also conducts a “stream survey” with the partners to ensure the new passthrough simulates what the streams were like before a road passed through them. He explains that those who built the roads in the past (some of these roads are more than a century old) didn’t know the culverts they were using were not sufficient to maintain the streams below the roads.

“People in those days were doing their best with what they knew. All they worried about was getting the water across, and they thought the fish would come no matter what,” Matt says. “Many of the culverts that were put in these streams were just rolled into the hole. In those situations, it created an artificial stream channel.”

Today, the work to determine the proper placement for a culvert is much more complex. During the stream survey, Matt and the partner agencies will view the streams 100 feet above and below the project area to understand what the stream would have done naturally.

“We’ll come back and mimic that with our design. It can drastically change where that structure is placed and at what elevation it’s placed,” explains Matt, shown below.

Handling culvert and bridge replacements with care

Culvert and bridge projects are handled with extreme care. Before any digging begins, a watertight pipe is used to divert the stream around the project area, and fish screens are placed to ensure fish don’t come into harm’s way. Work to place culverts or bridges only begins after the project area is fully dewatered.

“The allowable amount of sediment contamination in the stream is zero. We’re mindful of that 100 percent of the time,” Matt says.

During a recent project, he pointed out a crawfish who was curiously swimming near the diversion pipe in clear water, just feet away from the project, a testimony to how well the diversion pipe worked to keep the water clear.

At the same time, Kelly Dunkerson, site supervisor for John J. Karnas Co., was placing a 40-foot-long culvert into the streambed. The Hoquiam-based company has contracted with New England Forestry for more than 30 years and has served as a knowledgeable partner in the culvert and bridge replacement projects. While this particular culvert’s circumference was 10 feet around, about a third of that would be backfilled with streambed material to match the rest of the stream.

From start to finish, the projects typically take about a week, and then waterflow returns to normal. It can be shocking how quickly the streams attract salmon who have not been there in years. Portia, of WDFW, says they can sense the change in the waterflow once the work is done.

Matt says New England Forestry has about 40 more miles of habitat to open and 125 more structures to upgrade in order to fully comply with Forests & Fish, but the work won’t stop there.

“As we build new roads, eliminate roads, stream enhancements change and other dynamics change, we’ll continue to do this work,” he says.

Matt’s proud of the work New England Forestry is doing to help restore and improve salmon habitat in the forest.

“I love what I do every day of the week,” he says.
