However, it was not until the arrival of European settlers in 1600’s that major changes to the landscape truly began. To provide resources needed by these early colonists, forests were cut, wetlands drained, and rivers dammed. These human activities changed the land and adversely affected the biodiversity. In the late 1800’s the industrial revolution - and the resulting mechanized agriculture and increased water and air pollution, along with a burgeoning human population and residential and commercial development –put even more pressure on Delaware’s natural world. Many of these same pressures remain today, and new issues such as climate change and sea level rise continue to threaten Delaware’s remaining natural lands and biodiversity. The number one threat to biodiversity in Delaware is habitat loss and degradation. Delaware’s population continues to rise and the need for recreational, residential, and commercial space is leading to the development of much of the remaining open space. Hundreds of acres of open and forested land are being converted every year to suit these human needs. Continued sea level rise will also result in the loss or change of Delaware’s coastal habitats. The combined effects of these human-caused activities will result in the loss or modification of habitats and negatively affect populations of native plants and animals, often diminishing and sometimes eliminating species from our state. There are many local, county, state, and private efforts to combat this assault on Delaware’s... --- - Published: 2023-03-15 - Modified: 2026-04-20 - URL: https://delawarenaturally.org/ LEARN ABOUT USWHY IT MATTERSGET OUT AND EXPLORE What is Delaware Naturally?

Lorem Ipsum is simply dummy text of the printing and typesetting industry. Lorem Ipsum has been the industry's standard dummy text ever since the 1500s, when an unknown printer took a galley of type and scrambled it to make a type specimen book. It has survived not only five centuries, but also the leap into electronic typesetting, remaining essentially unchanged. It was popularized in the 1960s with the release of Letraset sheets containing Lorem Ipsum passages, and more recently with desktop publishing software like Aldus PageMaker including versions of Lorem Ipsum Why do we use it? It is a long established fact that a reader will be distracted by the readable content of a page when looking at its layout. The point of using Lorem Ipsum is that it has a more-or-less normal distribution of letters, as opposed to using 'Content here, content here', making it look like readable English. Many desktop publishing packages and web page editors now use Lorem Ipsum as their default model text, and a search for 'lorem ipsum' will uncover many web sites still in their infancy. Various versions have evolved over the years, sometimes by accident, sometimes on purpose (injected humor and the like). --- - Published: 2023-01-20 - Modified: 2023-07-05 - URL: https://delawarenaturally.org/delaware-biodiversity/ DELAWARE'S BIODIVERSITYDelaware is in the middle of the Mid-Atlantic region and has a generally mild temperate climate. The hilly northern area of our state is within the physiographic province called the Piedmont – the foothills of the Appalachian Mountains. The natural areas of the Piedmont include several diverse habitats including rivers, their spring-fed tributaries, non-tidal wetlands, deciduous forests, and open fields. The rest of the state is within the Atlantic Coastal Plain physiographic province. This flat, often sandy, area stretches from the Piedmont south to (and beyond) our southern border. Habitats on the Coastal Plain include: deciduous and coniferous woodlands, maritime woodlands, coastal dunes, slow-moving tidal and non-tidal streams, freshwater and saltwater marshes, and Delmarva Bays and other ephemeral wetlands. Each of these habitats contains hundreds of species of animals, plants, fungi, and other living organisms that are adapted to the physical and biological conditions of the habitat and dependent on the habitat for food, shelter, and procreation. Most of Delaware’s biodiversity has not been documented as very few surveys have been conducted on bacteria, fungi, and most insect groups. Only the plant, vertebrate (fish, amphibians, reptiles, birds, and mammals), butterfly, damselfly, and dragonfly groups are fairly well known. Even in these groups, species new to Delaware are still being found. There are many amazing natural phenomena that feature Delaware’s biodiversity to witness throughout the year. Some examples are: the spring blooming of wildflowers in our deciduous woodlands; the synchronized spawning of the horseshoe crab and northward migration of several... --- - Published: 2023-01-20 - Modified: 2023-07-05 - URL: https://delawarenaturally.org/habitats-ecosystems/ DELAWARE HABITATSAlthough small in land area, Delaware’s temperate climate; proximately to rivers, bays and coast and varied geology; results in a large variety of terrestrial and aquatic habitats. Delaware is a biological transition zone where northern plants and animals mix with southern species. Delaware’s Wildlife Action Report written by the Delaware Division of Fish and Wildlifeidentifies approximately 45 different natural habitats where many species of plants, animals, and abiotic elements come together, creating a complex, dynamic, and varied web of life. The northern tip of Delaware is comprised of the rolling hills, river-created valleys, and low ridges of the Appalachian Piedmont province. This region is also characterized by rocky, fast-flowing streams and rich deciduous forests dominated by oaks, hickories, tuliptree, and American beech. In the floodplains of the streams, diverse freshwater wetlands including marshes and vernal pools can be found. The remaining land in Delaware is the mostly flat Atlantic Coastal Plain, where slow- moving tidal and non-tidal streams flow either east to the Delaware River and Bay, west to the Chesapeake Bay, or south to Delaware’s inland bays. Fresh, brackish, and saltwater marshes are found along the streams and on the Delaware River and Bay and Atlantic coasts. Oak, maple, gum and American holly trees dominate the woodlands, often mixed with loblolly and Virginia pine as you move south. Maritime dunes and forests can be found along the Atlantic coastline as well as bald cypress swamps inland (the northern limit of bald cypress swamps in the U. S). Unique... --- - Published: 2023-01-20 - Modified: 2023-07-12 - URL: https://delawarenaturally.org/why-it-matters/ THE IMPORTANCE OF BIODIVERSITYE. O. Wilson says biodiversity is “all living things on the planet”. That makes Delaware’s biodiversity all living things within our boundaries including our territorial ocean waters. These living things are divided into five groups: Monera (bacteria), Protista (single-celled organisms), Fungi, Plantae (plants), and Animalia (animals). Although Delaware is a small state, it has plenty of biodiversity. The number of species is truly amazing – 1,419 native plants, 91 freshwater fish, 39 amphibians, 33 reptiles, 427 birds and 48 mammal species are found in Delaware. The number of Insect species is unknown but includes 118 damselflies and dragonflies, and 64 butterflies. Other insects such as moths, beetles, and flies, number in the thousands; and many species newly observed in Delaware are found each year. Biodiversity is everywhere-sit quietly in a forest, canoe on a pond or river, visit a vernal pool on a warm spring night, walk a beach along the Delaware Bay or Atlantic Ocean, or stroll through a meadow in mid-summer and Delaware’s biodiversity will envelop you. If you look closely, you will see the unseen (life that is either too small to notice or hidden most of the time). Examine what can be collected by using a dip net or plankton sein, or look under a decomposing log, and you will be amazed at the number and variety of life you find. Look through a microscope and open a window into a whole new world that is too small for the unaided human eye... --- - Published: 2023-01-20 - Modified: 2025-04-25 - URL: https://delawarenaturally.org/invasive-species/ NON-NATIVE INVASIVE SPECIESHundreds of species of non-native plants, animals, and fungi have been intentionally or unintentionally introduced into Delaware since the first arrival of European settlers in the 1600’s. These plants and animals were introduced for agricultural, horticultural, wildlife management and other reasons. Others were accidentally introduced. Some of these non-native species have responded to Delaware’s environment with great vigor, spreading aggressively into many natural habitats out competing native species. In addition, these foreign species had very few predators to keep their populations in check. These invasions continue to occur and many of our worst non-native species have been introduced in the past 75 years. Plants like Callery (e. g. , Bradford) pear, multiflora rose, autumn olive, bush honeysuckle, Japanese honeysuckle, oriental bittersweet, porcelainberry, mile-a-minute, English ivy, phragmites, and many other plants , can and do interrupt natural plant succession by smothering native plants. Animals - such as snakeheads, blue catfish, flat-headed catfish, several species of mollusks, and insects like the gypsy moth and emerald ash borer - can have serious, even lethal effects on native species and their habitats. To reduce these negative effects on natural plant and animal communities we must develop and implement major efforts of control. While eradication would be ideal, in practice it is very difficult to eliminate most specie, therefore the primary goal of most control projects is to reduce non-native populations to levels that have minimum impact on natural habitats and their processes. Efforts to combat the spread of non-native species are underway... --- - Published: 2023-01-20 - Modified: 2025-10-27 - URL: https://delawarenaturally.org/get-outside/ GET OUTSIDEExplore all the riches of Delaware during all seasons.

By understanding how high population density facilitates the spread of this fatal disease, we can better appreciate the necessity of local stewardship and the steps we can all take to protect the biological integrity of the First State. What Is Chronic Wasting Disease? Chronic Wasting Disease is a fatal, highly contagious neurological, illness affecting members of the deer family (Cervids). It spreads through direct contact and environmental contamination and can take years to show symptoms. To understand CWD, it is helpful to look at its "cousins" in the family of diseases known as spongiform encephalopathies. This complex name simply describes diseases that cause the brain to develop tiny holes until it resembles a sponge. Much like "Mad Cow Disease" in cattle or Scrapie in sheep, CWD is not caused by a virus or bacteria. Instead, the culprit is a prion. A prion is a misfolded protein that triggers a chain reaction, causing normal proteins in the brain to misfold as well. This process leads to listlessness, abnormal behavior, and eventual death. Because these prions are not "alive" in the traditional sense, they are incredibly resilient. They cannot be destroyed by standard disinfectants, heat, or seasonal weather changes. The Connection: Density and Transmission of CWD CWD is shed by infected animals through saliva, urine, blood, and feces.... --- - Published: 2026-04-06 - Modified: 2026-03-23 - URL: https://delawarenaturally.org/delaware-naturally/vernal-pools-at-risk-in-delaware-looking-deeper-through-the-window-into-the-water-table/ Vernal Pools: A Fragile Future for Seasonal Wetlands Vernal pools may only appear for part of the year, but the threats they face are constant. Across Delaware, these small wetlands are increasingly vulnerable, often overlooked in planning decisions and largely unprotected by current laws. In our previous post, Windows Into the Water Table, we explored what vernal pools are, how they form, and why they matter to the ecosystems around them. Now, we take a deeper look at what’s putting these habitats at risk—and what it will take to protect them before they disappear. Under Threat: What’s Putting Vernal Pools at Risk? 1. Development and Habitat Loss Construction is one of the biggest threats. Vernal pools are often filled or built over to make room for homes, roads, or agriculture. This destroys not only the pools themselves but also the surrounding forests that amphibians depend on for most of their lives. Roads also create deadly barriers during seasonal migrations. 2. Pollution and Runoff Runoff from lawns, farms, and roads carries fertilizers, pesticides, and salt into these pools. Amphibians are especially vulnerable because their permeable skin absorbs pollutants directly from the water. Even small amounts of contamination can disrupt entire ecosystems. 3. Climate Change Changing weather patterns are disrupting the delicate timing of vernal pools. Some dry too quickly. Others fail to fill at all. Rising sea levels in coastal areas can also introduce saltwater into freshwater systems, making them unsuitable for many species. 4. Invasive Species and Human Encroachment Habitat... --- - Published: 2026-03-23 - Modified: 2026-03-23 - URL: https://delawarenaturally.org/delaware-naturally/windows-into-the-water-table-what-are-vernal-pools-and-why-they-matter/ Vernal Pools: Hidden Habitats in a Changing Landscape They appear briefly, vanish quietly, and are easy to miss. But for a few critical months each year, Delaware’s vernal pools come alive with the calls of wood frogs, the flash of salamanders, and the shimmer of newly laid eggs. These small, seasonal wetlands, which are temporary by nature, but permanent in importance, are among the most ecologically rich habitats on the Delmarva Peninsula. Yet many people pass by them without ever realizing what they are. Why care about something so small, so fleeting? Because for the right species, in the right season, a single pool holds an entire world. What Are Vernal Pools? Vernal pools, sometimes called seasonal ponds or Delmarva bays, are shallow freshwater depressions that form in low-lying forested or upland areas. They fill in late fall and winter as groundwater rises and precipitation collects, then dry out by late summer as the water table drops. What makes them unique is their isolation. No streams flow in or out, which prevents fish from entering. That absence of fish creates a rare and critical safe zone for amphibians and invertebrates to reproduce. Most vernal pools in Delaware are small, often less than an acre, and irregularly shaped. Their temporary nature is not a limitation, but a defining strength that supports highly specialized life. Most vernal pools in Delaware are under an acre. An estimated 1,500 to 2,500 of these pools are scattered across the Delmarva Peninsula Origins and Distribution of... --- - Published: 2026-02-05 - Modified: 2026-02-05 - URL: https://delawarenaturally.org/delaware-naturally/oh-deer-the-cost-of-overpopulation/ White-tailed deer overpopulation in Delaware is driving the loss of native plants, insects, birds, and healthy forests while increasing invasive species and human-wildlife conflicts. Learn why active deer management is essential for biodiversity, ecosystem resilience, and public safety. Read the blog post here. Written by Mike Groome Healthy Ecosystems and Natural Balance Healthy ecosystems rely on checks and balances among all species, plant and animal alike. Foxes prey on smaller animals like mice, squirrels, snakes, and amphibians. In turn, amphibians such as frogs consume insects, worms, and even small fish. These interactions occur across every ecosystem and explain how energy moves through the food web. They are also what allow ecosystems to remain resilient, genetically diverse, and functional over time. Loss of Predators and Deer Imbalance When a species is lost, especially a keystone species, ecosystems begin to unravel. We are seeing this clearly with white-tailed deer (Odocoileus virginianus), not only in Delaware but across much of the country. Historically, wolves and other large predators kept deer populations in check at sustainable levels. In the absence of these predators, the only remaining controls on deer populations are vehicles and hunters. Current deer populations across Delaware often exceed 100 to 150 individuals per square mile. Ecologically sustainable levels are closer to 10 to 15 per square mile, meaning in many places, deer populations are often ten to fifteen times higher than what our forests can sustain. Why Deer Overpopulation Matters to Native Plants Why does deer overpopulation matter, and what does it mean for ecosystems? Deer preferentially browse native plants. In forest ecosystems, this browsing pressure prevents regeneration by consuming seedlings and young plants faster than they can recover. When populations exceed an ecosystem’s carrying capacity, native plant communities collapse. This matters because native... --- - Published: 2026-01-14 - Modified: 2026-01-14 - URL: https://delawarenaturally.org/delaware-naturally/under-the-surface-learning-from-the-winter-landscape/ Winter landscapes may look still, yet important ecological processes continue quietly beneath the surface. In this post, we explain how observing your winter garden, and avoiding unnecessary disturbance, helps maintain the conditions that overwintering organisms depend on for a successful spring emergence. Read the blog post here. The Illusion of Rest: A Glimpse Under the Surface January in Delaware often feels still at first glance. The garden is quiet, the soil is firm, and the remnants of last season seem frozen in place. But under the surface, important ecological processes continue. Deep winter is the phase where habitat does its hidden work, and understanding these patterns helps gardeners care for their landscapes without disturbing the wildlife that depends on them. Check out our blog post, The Quiet Work of Winter, to learn more. What’s Really Happening Under the Surface of the Winter Landscape Much of winter’s activity invisible. Beneath a thin layer of leaf litter, fungi continue breaking down organic matter, insects remain dormant in soil pockets, and root systems can stay active even in cold conditions. These quiet processes keep the ecosystem functioning until spring. As temperatures rise and fall, the ground responds. Soil expands and contracts through natural freeze–thaw cycles, though the severity of these shifts depends on how much insulation is present. Where snow, leaves, or plant debris remain, the surface experiences fewer abrupt temperature swings, creating steadier conditions for dormant insects, soil life, and overwintering seeds. In exposed areas, these fluctuations are more frequent and can place additional stress on organisms close to the surface. In places where snow or leaf cover lingers, small insulated pockets form between the ground and the material above. These tiny air spaces act as natural micro-tunnels that stay slightly warmer than the surrounding air. They create reliable... --- - Published: 2025-12-01 - Modified: 2025-12-03 - URL: https://delawarenaturally.org/delaware-naturally/the-quiet-work-of-winter/ Doing Less is Doing More: The Quiet Work of Winter Winter arrives quietly in Delaware. Frost settles across seed heads, leaves collapse into soft layers, and the garden seems to withdraw into stillness. Yet beneath that calm surface, the quiet work of winter has already begun as wildlife enters its most fragile season. Early winter is not the moment for sweeping the yard clean. In fact, the most meaningful action homeowners can take is to simply do less. Winter’s Subtle Shelter The stillness of December hides a surprising amount of life. As temperatures drop, many species settle into overwintering strategies that depend on undisturbed natural cover. Bumblebee queens slip into shallow soil or loose leaf piles. Firefly larvae hunt and develop within leaf litter. Butterflies and moths overwinter as chrysalises nestled among curled leaves or attached to stems. Winter birds such as goldfinches and sparrows continue to forage from dried seed heads long after the first frost. These species survive because the garden is allowed to remain intact. When leaves are removed or stems cut down too early, the habitat they rely on disappears. Supporting Early-Winter Habitat Early winter is about restraint. The following steps help protect overwintering species—many of which will remain hidden until spring. Leave the Leaves: Leaf litter acts as a natural insulating layer. It stabilizes soil temperature, protects developing insects, and gradually improves soil health as it breaks down. Allowing leaves to remain in place supports a wide range of wildlife with virtually no effort.

From Forests to Lawns: How Delaware’s Landscape Has Changed Before European settlement, Delaware’s uplands and bottomlands were largely continuous forests. Old, diverse stands covered the hills, and swamp forests and wooded wetlands braided through lowlands and tidal areas. Indigenous stewardship used careful fire and selective clearing but left the overall canopy intact. Forests filtered water through soils, kept microclimates cool and humid, and supported a full array of wildlife that had evolved in those conditions Colonial clearing changed the system quickly. Forests were felled for agriculture and timber. Streams were dammed and redirected. Wetlands were ditched and drained. By the early twentieth century, the state had lost roughly three quarters of its original forest canopy. The stands that remained were mostly young secondary forests that lacked the structural variety of old growth. Creek channels had shifted, hydrology had been altered, and nutrient and sediment pollution had become a chronic threat to water quality. A second transformation followed the Second World War. Farmland and remaining woodlots gave way to subdivisions, shopping centers, and new roads. Turfgrass lawns became the cultural default. In Delaware’s suburbs today, the typical yard is a wide, mowed lawn with a few isolated ornamentals. Lawns require mowing, fertilizer, and irrigation, but they do not filter water like a forest floor, they do not hold soil with deep, varied roots, and they do not... --- ---
