Palmyra Cove is a 250-acre urban oasis along a highly developed area on the Delaware River. Habitats include wetlands, woodlands, meadows, wild creek and river shoreline, and a freshwater Tidal Cove after which the cove is named.
The Institute for Earth Observations at Palmyra Cove is a STEM educational initiative for students and teachers that studies Planet Earth. This is a unique and engaging facility where experiences can be shared…and innovative collaboration begins!
Invasive Species: A Growing Threat to Ecosystems, Agriculture, and the Economy
Invasive species are non-native plants, animals, pests, and diseases that cause harm to the environment they invade. In the United States, these invaders have spread into nearly every terrestrial, wetland, and aquatic ecosystem, with annual economic losses estimated at $137 billion. As global travel and trade increase, so do the risk of new invasions.Healthy ecosystems are essential to life—purifying air and water, decomposing waste, and storing carbon. But invasive species disrupt these natural processes, threatening biodiversity, forest health, crop yields, and even human infrastructure.

Invasive Insects of Major Concern
The USDA monitors and manages several high-impact invasive insect pests, many introduced from other countries:
• Asian Longhorned Beetle: Bores into hardwood trees, cutting off their nutrient flow and leading to death.
• Emerald Ash Borer: Has devastated ash tree populations across the U.S.
• Spotted Lanternfly: Damages vineyards, fruit trees, and ornamentals by feeding and spreading sooty mold.
• Spongy Moth (formerly gypsy moth): Strips foliage from trees, weakening forests and urban landscapes.
• Brown Marmorated Stink Bug: Damages fruit and vegetable crops and invades homes.
• Khapra Beetle: Threatens stored grains and dried food products.

How Invasive Insects Spread
These pests often spread through:
• Imported goods (containers, pallets)
• Agricultural equipment and materials
• Personal travel (firewood, vehicles, outdoor gear)

What You Can Do
• Be Informed: Learn to recognize invasive species and report sightings to the USDA.
• Clean, Drain, Dry: Thoroughly clean boats and gear to prevent aquatic spread.
• Buy Local Firewood: Never move firewood long distances.
• Report: Alert authorities to any unusual pests or plant diseases.
Why Research and Action Matter
Invasive species research helps us detect, manage, and prevent outbreaks. The USDA plays a critical role—but public awareness and cooperation are essential. Protecting ecosystems today means securing our environment, economy, and health for tomorrow.
