How We Work: Healthy Forests
Enabling habitats, wildlife and communities to thrive in the face of a changing climate.
Appalachian forests encompass a diversity of life virtually unrivaled in the temperate regions of the globe. As the climate changes and species move, we need even more from these forests.
The Central Appalachians are the water tower for the mid-Atlantic. More than 6 million people in the D.C. metro area get their drinking water from the Potomac River, which flows from the cool mountain streams that form and converge in the forested mountains to the west. Those forests naturally filter our water as it falls from the sky and gradually moves across the landscape toward our faucets.
The forests of the Central Appalachians not only filter our drinking water, they support a diversity of life virtually unrivaled in all other temperate regions of the globe. They are home to 140 kinds of trees, 78 different mammals, 76 amphibians, 250 species of bird, and thousands of other varieties of life.
As climate change brings warmer temperatures and new weather patterns to the Appalachians, plants and animals are shifting their ranges. Western Maryland in particular is a critical migratory channel. Keeping the Appalachian forests healthy and connected will allow people and nature to adapt and thrive.
Keeping our western Maryland forests healthy and connected requires diverse skills, experiences and partnerships. We use science to better understand forest health and resilience. We rely on decades of land management experience to lead the way on sustainable management that keeps priority forests connected and healthy. And we engage people living in Appalachian communities to help them keep forested land connected and healthy for future generations.
Families and individuals own 70% of the forests in western MD, so woodland owners play a critical role in conserving Maryland’s forests and the wild creatures that call them home.
Threats such as invasive species, insect pests and drought are damaging forests and degrading wildlife habitat, but addressing these threats can be challenging. In 2018, TNC conducted a mail survey of 2,000 landowners in western Maryland to better understand their goals and needs.
The survey found that a strong majority of landowners are interested in wildlife habitat and forest health. However, more than half of the respondents to the survey did not have a written plan in place for managing their forests despite the financial benefits that a forest management plan can provide. Nearly 80% of respondents had never taken advantage of educational resources or expert advice to assist with forest management.
We're working to close that gap through the Family Forest Outreach Program. The program's specialist will help landowners in Garrett and Allegany Counties find information, financial resources or expert advice that best meet their current needs to improve forest health and wildlife habitat on their land.
Restoring Red Spruce
Red spruce (Picea rubens) once covered thousands of acres in western Maryland. Logging and subsequent wildfires at the turn of the 20th Century drastically reduced its range. It's estimated that in the Central Appalachians as much as 90% of the original red spruce forest is now gone.
But we're working to change that statistic - one seedling at a time.
We’ve been planting red spruce in western Maryland nearly every year since 1996, and have begun re-visiting sites planted 10 years ago in order to introduce age diversity. Over the past 22 years, volunteers have planted more than 62,000 red spruce trees in the forests of western Maryland.
Our efforts will help improve habitat quality for rare plants and animals, help rebuild carbon-rich soils, improve hydrology and local climate, and reduce erosion and increase percolation of water into the underlying bedrock.
It's a pretty good payoff for a spring day spent in a beautiful place!
One of the most reliable ways to boost forest health is by reintroducing fire.
We know that fire is as natural and necessary as rain in these forests, but the more we understand about how and when fires occurred historically, the better we can replicate those natural events through safe controlled burns.
To fill gaps in our knowledge after decades of fire suppression, TNC funded an Arcadia University study of fire scars preserved in the rings of “recorder trees” dating back as far as 1797.
The science of tree-ring dating, or dendrochronology, tells us more about a tree than just its age. Tree rings present an intricate story of the climate and environment in which the tree grew each year of its life. And when we compare the story of one tree with the stories of dozens of others within a given landscape, a fuller, and sometimes smokier, picture emerges.
Limited resources, including equipment and personnel, is often an obstacle to implementing a successful fire program. In 2016 we led the expansion of the Central Appalachian Fire Learning Network, a collaboration between TNC and multiple state and federal agencies.
We have partnered with the Maryland Department of Natural Resources and the U.S. Fish & Wildlife Service to conduct burns across more than 660 acres of woods and wetlands on Maryland's Eastern Shore since 2007. Applying FLN's collaborative model successfully in western Maryland is a critical next step in keeping some of the state’s most valuable natural resources healthy and thriving.
The benefits that fire can bring to a landscape are remarkably varied. Many species of plants and trees have evolved to be fire-adapted, and may not grow or disperse their seeds until after a forest has burned.
Fire enhances a forest’s overall biodiversity, and by doing so makes it more resilient. When a stand of trees includes many different species rather than a few, they’re less likely to be wiped out by threats like pests or disease. And that resilience is crucial for the species and communities that depend on the services a forest provide.
By joining forces and pooling resources, we will dramatically scale up the size of our burns — and accelerate our progress toward the healthy forests of the future.
Fire Learning: Belize
TNC fire practitioners are skilled at conducting controlled burns, but don't often have opportunities to train for wildfire scenarios. In February 2019, Stewardship Field Assistant Chase McLean traveled to Belize for a TNC sponsored training focused on wildfire suppression.
The training, held at the 60,000 acre Deep River Forest Reserve, allowed participants to work at a scale that's not possible on TNC land and experience a diversity of fuel types, fuel configurations, and fire behavior.
During this training, Chase was able to complete his FFT1 Firefighter Type 1, or Squad Boss qualification task book and initiate his Single Resource Boss task book. These new qualifications will allow Chase to take on a greater leadership role in the chapter's prescribed fires and bring some of the skills and knowledge learned in Belize to Maryland's fire management program.
LEADERS FOR THE FUTURE
The LEAF program provides students from western Maryland's Allegany and Garrett Counties with the opportunity to explore local forest landscapes and learn about careers in conservation. The LEAF interns are diverse in gender, aspirations, and socioeconomic backgrounds, but the students all share a common interest: environmental conservation.
For two weeks in mid-July, the cohort of six students took part in hands on field experiences. Ranging from high school juniors to recent graduates, the youth contributed to a variety of land management projects on TNC preserves.
The group helped to install a beaver baffle at Finzel Swamp Preserve; cleared space for larch trees; collected deer ticks for a study being conducted at Frostburg State University; built and installed a new interpretive sign at the Sideling Hill Creek Preserve; and utilized the iNaturalist app to identify and map mushroom species.
The students were also exposed to the role of policy in conservation. They took the lessons learned from the chapter's vigorous youth advocacy training program and put them into practice during a day spent meeting with local Allegany County elected officials.
Every seedling we plant, every acre we burn and every tree we measure is all part of a strategy to not only restore healthy forests, but also to serve as a model for land managers across the Appalachians. The Nature Conservancy in western Maryland is restoring forests to safeguard their health and ensure their resilience to changing conditions.
