Frederick County Office Welcomes New Hires
Amy Rembold named as the new Master Gardener Coordinator and Home Horticulture Educator. Born and raised on a dairy farm in Frederick County, Maryland, I have deep roots in the community I proudly serve. Growing up amid the agricultural landscapes and natural beauty of the Catoctin Mountains instilled in me a lifelong appreciation for the environment and a strong belief that stewardship of our land and water is a responsibility we owe to future generations. After spending more than nine years living overseas, I encouraged my family to return home to Frederick County, reaffirming my long-term commitment to this community and its future.
I hold a Bachelor of Science in Forestry & Wildlife from Virginia Tech and a Bachelor of Arts in Art History from Hood College. My passion for environmental stewardship has been shaped by both local and global experiences. After college, I married a military officer and lived in India, Nepal, and Bangladesh, where I witnessed firsthand the daily realities of poverty, limited access to clean water, and severe air pollution. These experiences broadened my understanding of environmental challenges and reinforced my conviction that the choices we make in our homes and communities—no matter how small—have global consequences. This perspective guides my work with the University of Maryland Extension, where I serve as Master Gardener Coordinator and Home Horticulture Educator. In this role, I develop, organize, and deliver science-based educational programs on horticulture, sustainability, and environmental stewardship, reaching thousands of residents through seminars, workshops, outreach events, and community partnerships. I coordinate and manage a highly active Master Gardener program of more than 100 volunteers, lead recruitment and training efforts, and serve as the primary point of contact for home horticulture inquiries across Frederick County. Beyond the Master Gardener program, I serve as Chair and member of the Frederick County Sustainability Commission and as a 4-H Unit Leader at Lincoln Elementary School, where I established the county’s first after-school 4-H club. Through hands-on gardening, pollinator habitat creation, and civic engagement activities, I work to inspire the next generation of environmental stewards. My efforts include securing and managing multiple grants, developing native and pollinator landscapes at Title I schools, coordinating the Seed to Supper program, and supporting local food security initiatives through the donation of hundreds of pounds of fresh produce to the Frederick Food Bank. In recognition of my commitment to volunteerism and community service, I was honored as the 2025 Wertheimer Fellow for Excellence in Volunteerism and awarded a $25,000 endowment to support local initiatives. I also helped establish the Frederick County Master Gardener Foundation to provide scholarships for Frederick County students pursuing education at the University of Maryland.
I am deeply committed to the University of Maryland Extension’s mission to deliver research-based education, strengthen communities, and promote environmental stewardship. Through collaboration, education, and service, I strive to ensure that Frederick County remains a healthy, resilient, and vibrant place to live for generations to come.

Marylanders Online
At Marylanders Online, we believe that digital literacy is a must, not a choice. In today’s world, being able to navigate the digital world and knowing how to use technology is a necessity, while not everyone is given the privilege and ability to do so. On that note, the University of Maryland Extension (UME) in collaboration with the UMD College of Information Sciences initiated the Digital Literacy Project with a desire to bridge the digital divide among Marylanders.
Our mission is to bring digital inclusion to Maryland by providing quality resources and education that help improve digital literacy. This website will be a one-stop shop for that mission, open to anyone who wants a little guidance or self-guided learning opportunities.
Our Get Help page provides instructional materials for self-guided learners. Our Give Help page is perfect for educators or those who want to make a difference in their community by sharing their knowledge. Furthermore, the Get Connected page provides information and resources to help Marylanders stay connected to the digital world, such as connectivity programs and WiFi locations.
We believe that digital literacy is more than just a skill but a way to connect people and communities. Join us on our mission to get connected, stay connected, and enjoy being connected!

Pond maintenance does not require a permit; however, pond construction, repair, or modifications will likely require a permit from the Maryland Department of the Environment (MDE). For more information, visit MDE's Dam Safety Permits web page, or call their office at 410-537-3538.
The Natural Resources Conservation Service (NRCS) is a branch of the U.S. Department of Agriculture. They may have information regarding the size of a pond, its age, data on when the pond was built and its specification at that time, materials on renovating it, and local contractors who may provide construction/renovation services. They are often able to calculate size by using aerial survey records. The Frederick County NRCS Office can be reached at 301-695-2803. [If you search 'ponds' on their website several web pages are available to view].

Tick Information
Assistant Professor Jennifer Mullinax, a wildlife ecologist in the Department of Environmental Science and Technology, is leading studies in Maryland to reduce tick-borne illnesses. She breaks down what ticks are, where they live, the risks they pose and how we can best protect ourselves.
What is a tick?
It is an arachnid, not a true insect, essentially a parasite that has to feed on a host to transition from one life cycle (larva, nymph, adult) to the next.
Where do they live?
They love brushy, scrubby stuff. Think of an overgrown edge of a trail, a power line right-of-way or a yard that backs up against natural areas—all of those are often full of ticks. The heaviest hotspot for ticks that spread Lyme disease is in the Northeast, but different types of ticks live across the United States, and their range is expanding.
How do ticks infect humans?
They don’t jump, they don’t fly, they don’t drop off of things. They climb up a bush or tall grass, wave their little arms and wait for something to brush by, then they latch onto you.
Typically, they’re not born with diseases. It’s when they feed on an animal like a deer or mouse that they pick it up. Then, when humans get bitten, we become infected.
What diseases do they carry?
Blacklegged ticks spread Lyme disease, which is a huge issue. If it’s caught early, you can take antibiotics, but if not, it can become a chronic disease, with severe joint pain, inflammation, headaches and more. They can also spread anaplasmosis, which causes fever, chills and muscle aches. Lone star ticks, which have a white spot on their backs, can carry the Alpha-gal molecule, which sets off a red meat allergy.
We expect to see more tick-borne diseases with climate change, as more places become hot and humid. We’re not having the freezes we used to that would knock back tick populations.
What can people do to avoid getting these diseases?
It’s shocking, but you have no idea they’re on you—they’re so light. So the first thing I would say is you need real bug spray: permethrin. Not citronella, none of those herb-y things. Spray it on your clothing and shoes outside, let it dry, then wear it.
Choose long pants and close-toed shoes. My students tuck their pants into their socks, and some even use duct tape around their ankles, to make sure there are no gaps for the ticks to crawl into.
Do diligent tick checks. My kids play in the woods every day, and during tick season, from May to October, we do a full body check every night. That means naked, in the mirror, looking at every crevice: between your legs, under your arms, behind your ears, etc. The tick needs about 24 hours to do a full blood exchange, so if you get them off quickly—I aim for less than 12 hours—you can feel confident it hasn’t had time to give you anything.
How can people protect their yards?
You can create a three- to four-foot mulch barrier between your property and any woods or brush, to limit the green surface area ticks can crawl across and brushy vegetation. You can also fence your property to keep deer out.
If you’re in a really tick-y area, get tick tubes. You can buy them premade from any home improvement store, or you can make them with cotton balls soaked in permethrin placed inside toilet paper rolls. Spread them around your property, so the mice take them back to their nests and repel ticks. They both have short lifespans, so if you do this for a couple of years, you can really reduce the prevalence of these diseases.

Maryland Department of Health - Tick ID through the University of MD; this is only for ID and not to test for Lyme Disease.
The University of Rhode Island has labs listed for Tick ID and Lyme Disease testing.
Mosquitos
Wearing repellants and eliminating standing water to reduce mosquito breeding sites in your yard are two of the most effective things you can do to protect yourself from mosquito bites. In some communities, spraying for mosquitoes may be done to control large populations and/or mosquito-borne diseases. Find out more - Controlling Mosquitos
Beekeepers
