  • The highly controversial and extremely invasive Himalayan blackberry is might be considered the classic success story if looked at from the the view of this extremely aggressive invasive plant. Why it is called the Himalayan blackberry is a mystery to me, but it originally comes from Armenia and Iran. Introduced to the East Coast of the United States in 1885, it is believed it was confused with a similar European species of blackberry and with the help of local birds who absolutely love the berries, it had reached reached the West Coast of North America. This plant grows fast, easily outcompetes native foliage and is extremely tough to eradicate. On the plus side, this particular blackberry puts out bumper-crops of blackberries every summer that are absolutely delicious. I often see bushes laid out flat on the ground under the weight of all the berries. These were found growing in the Woodard Bay Conservation Area just outside of Olympia, Washington.
    Himalayan Blackberry (Rubus armeniacus)
  • When looking at the flower of the Himalayan blackberry, it's easy to see that it actually is a member of the rose family. A favorite of bees and loads of other wildlife who love the delicious sweet blackberries that come later in the summer, this highly invasive import which is actually from the Armenia area (not sure where the  Himalayan part of the name comes from)  thrives in the Pacific Northwest and is a major pest for gardeners and forest stewards all over the region. This one was found in the Woodard Bay Conservation Area just outside of Olympia, Washington on a beautiful summer afternoon.

  • Sheep sorrel is a very widespread invasive member of the buckwheat family that originated from the Mediterranean region of Eurasia. Found in every state of the US and in every province of Canada, it is usually found in disturbed areas from the coastline to the sub-alpine elevations of mountain ranges across North America.
    Sheep Sorrel
  • Considered non-native and invasive from Europe (although there is some speculation that there is an American native subspecies) the elegant and creatively named common reed is an important wetland grass that is found in every state and province in North America except for Hawaii and Alaska, ranging as for north as the Canadian Northwest Territories. Growing to heights of 20 feet (6 meters) this enormous aquatic wetland grass can grow massive thickets providing refuge, seeds and food for wildlife. These were found and photographed in Hidalgo County in South Texas on the Rio Grande, which forms the US-Mexico border.
    Common Reed (Phragmites australis)
  • While superficially it looks like your common dandelion, the common cat's-ear is an invasive Eurasian species of aster that has run wild in the Pacific Northwest, particularly west of the Cascade Mountains where it is listed as a noxious weed. This one was found about 15 miles to the northwest of Mount Rainier in Washington state in an open field by the Carbon River.

  • Although this impressive and well-known succulent is known around the world as one of the most common houseplants in the world, Kalanchoe daigremontiana goes by dozens if not more common names such as devil's backbone, alligator plant, Mexican hat plant, good luck plant, mother of thousands (should be mother of a thousand names), it is considered invasive and unwelcome outside of it's native Madagascar. It spreads very easily and even thrives in arid, dry environments because the little "baby" plants develop in the hundreds and thousands on the edges of the leaves, drop off and start new plants. This one was one of literally thousands of them growing in a nature preserve in Harlingen, Texas in the Lower Rio Grande Valley.
    Alligator Plant (Kalanchoe daigremon..ana)
  • An unusual hybrid find! Although kalanchoe succulents are known around the world as some of the most common houseplants in the world, this one goes by dozens if not more common names such as devil's backbone, alligator plant, Mexican hat plant, good luck plant, mother of thousands (should be mother of a thousand names), it is considered invasive and unwelcome outside of it's native Madagascar. It spreads very easily and even thrives in arid, dry environments because the little "baby" plants develop in the hundreds and thousands on the edges of the leaves, drop off and start new plants. What is unusual about this one is that it is actually a hybrid of two Kalanchoe species, both from Madagascar: Kalanchoe daigremontiana and Kalanchoe delagoensis. This one was one of literally thousands of them growing in a nature preserve in Harlingen, Texas in the Lower Rio Grande Valley.

  • These very beautiful bittersweet nightshade berries found ripening on the vine are native to Europe and Asia, and arrived roughly in the 1860's and were used by the Makah Indians as a medicine for stomach issues. Now naturalized throughout most of North America, this relative to the potato is an invasive weed that can grow in huge thickets and can compete with native plants. This plant is known to be VERY DANGEROUS to both humans and other animals and has caused people to die. It is said that once the berries are fully ripe (when they are bright red) that the amount of solanine - the toxic alkaloid, is greatly reduced. Seeds are spread by the common song sparrow and a few other birds that eat them, who are unaffected by the poisons the berries carry.

  • The rosary pea is an invasive vine from Asia and Australia that has found a home in Florida, Georgia, Alabama and Arkansas. While these "peas" may be useful in many shaker-percussion instruments, the black and red fruits are highly toxic. One ingested pea had the potential to be fatal to a healthy adult. This cluster of rosary peas was found in a suburban neighborhood in Fort Myers, Florida.

  • Considered an invasive species in North America, the Peruvian primrose-willow was introduced into the Sunshine State and many other places around the world for its beautiful yellow four-petalled flowers. These days it is a serious problem due to how fast this tall very bush grows and how easily it spreads, outcompeting coastal native plant species in Florida, Alabama, Mississippi, and the Texas Gulf Coast. This one was photographed in the Fakahatchee Strand in Collier County, Florida.

  • The parrot gladiolus is one of the ever-increasing number of once-invasive, now naturalized species of plants that have become wild and are commonly found throughout parts of North America. This gladiolus is native to South Africa and are becoming increasingly common throughout the American Southeast. This one was photographed south of Thomasville, Georgia. The largest populations I've seen in the wild were in the salt marshes of Florida's northern Gulf Coast.

  • The mouse spider is a beautiful, velvety (hence the name) brown spider and accidental European import that has established itself across much of North America. This speedy predator does not use a web to catch prey, but rather prefers to chase down and overpower insects and other spiders. At less than an inch in length, this spider is completely harmless to humans, unless you are in fact the size of a cricket. This mature female was found under a rock between Ellensburg and Vantage, Washington while hunting for scorpions.

  • This South African native succulent perennial with its very attractive bright pink and/or yellow flowers has found its way to both California and Florida thanks to the ornamental plant industry and has particularly found a foothold along Southern California highways, earning it the nickname "highway ice plant." Originally used as a soil stabilizer due to its matting, ground-cover nature it has unexpectedly spread into several sensitive ecological habitats such as coastal communities and desert dune habitats where it quickly outgrows and outcompetes threatened and endangered plants. This one was found growing in a sprawling mat across the sandy beach in Los Angeles, California next to the Del Rey Lagoon.

  • Found almost everywhere in North America from the tropics to the arctic circle, white clover is a naturalized, non-native member of the pea family deliberately brought to the New World as a high-protein food crop for grazing livestock. This one was part of a large patch growing in Northern Arkansas.
    White Clover
  • The intensely and wildly vibrant blue cornflower is found throughout most of North America, but is actually native to Europe, and is only naturalized here. Oddly enough, it is becoming rare and has disappeared completely from many places where it once flourished in the Old World. This one was photographed next to the Columbia River on the Washington side of the Columbia River Gorge.

  • The green iguana, also known as the American iguana is a large attractive and often strikingly-colored lizard in the Iguanidae family that is native to the Caribbean Islands, Central America and most of the northern half of South America. Although they are are herbivores and are not particularly dangerous to humans or other animals, they do adapt to new environments very well and are a very special species of concern in places where they have naturalized (most likely as escapes from the pet trade, as they make very friendly and docile pets when raised by humans). Green iguanas are now found in Florida, Nexas, Puerto Rico and Hawaii where these enormously strong lizards burrow into the sides of canals and riverbanks causing unnecessary erosion and damage, destruction of rare native plants other species depend upon, as well as decimating gardens and landscaping. This 6-foot beefy male was found on the side of the road with around 200 other well-fed adults along a one-mile stretch on Key Largo, Florida.

  • This huge batch yellow flag iris was found growing along the Yakima River in great profusion the eastern bank of the Yakima River, just north of Selah, WA. Although incredibly beautiful, they are considered a pest as they completely take over river banks. Because they lack the diseases and wildlife that eat them found in their native Europe, they can multiply unchecked - crowding out North American native plants that don't enjoy such an easy advantage.

Unlike our native green mint and dead-nettle species, this native of Turkey, Iran, and Armenia has very attractive furry silvery leaves, which explains why it made its way to North America in the first place, as it was once popular in gardens with families with children. This one was photographed in Northern Arkansas.

  • Common across nearly all of North America, common burdock look slike just another thistle, except that it actually isn't a thistle at all. A native of Europe, bats have been known to die after becoming entangled in the burrs.

  • This pretty little bright yellow flowering pea is an invasive plant from Eurasia and Northern Africa and Africa that has taken over large parts of North America where it was once used to help control soil erosion in agricultural areas. These "escaped" plants were found growing in abundance along Soos Creek in Kent, Washington on a cloudy summer day.

  • A western pond turtle basks in the sun on a beautiful California day on Lower Klamath Lake near the Oregon border. Listed as a vulnerable/threatened species, these small turtles are slow-growing, often maturing at around 10 years old and are taking a hard hit from invasive bird and animal species - especially bullfrogs and bass.

  • Engelmann's prickly pear is one of the most (if not the most) widespread of the prickly pear cacti. It is found in all of the American Southwestern States (except Colorado) and can even be found as far east as Louisiana, Mississippi and Missouri and is widespread throughout much of Mexico. Oddly enough , it has become an invasive species in Kenya! The sweet, juicy fruits are a traditional and still very important food source wildlife an for many tribes and nations of the Native Americans and is commonly used in Latin American cuisine.

  • The brown anole is a member of the spiny lizard family and native to Cuba and the Bahamas. Common, and invasive to the United States, it is spreading north from the Florida Keys, and in a little more more than a century it has established itself as far north as Georgia and as far west as Texas in recent years. The problem with this particular species is that it is outcompeting with the native and less aggressive green anole, with the additional pressure of adult male brown anoles having been known to prey on young green anoles. This one was one of many spotted scurrying around hunting among the trees one November evening in the Corkscrew Swamp near Naples, Florida and the nighttime insects started to come out.

  • This distant relative to the pineapple is endangered in the wild in North America. Confined to a few remaining counties in locations far out into the Florida Everglades and Puerto Rico, it is listed as a threatened species. Major concerns for this species are habitat loss and an invasive exotic weevil (Metamazius callizona) found in South Florida that kills it. Luckily this species is also native to Brazil, Venezuela and Bolivia, where populations are more stable. This one was photographed in SW Florida's Fakahatchee Strand. Look closely and you will see it sharing a limb with native zig-zag orchid (Epidendrum rigidum) in this submerged pond apple tree.

  • Native to Britain and Ireland, bluebells are found growing wild across most of North America. Although invasive, these common and spectacularly beautiful wildflowers are found in rich soils - such as these early summer bloomers found growing along the lower slopes of the Cascades Mountains in Northern Oregon.

  • This beautiful member of the carnation family is not native to North America, but is so widespread that it is now called naturalized instead of invasive. This one was photographed in King County, Washington.

  • I've spent over a decade telling everyone I know that this beautiful member of the Balsaminaceae of plants was an invasive, exotic species from Asia and I was completely wrong. I recently discovered that it is natively found near wetlands and streams in all over North America except the arid American Southwest, Wyoming, Montana and Alaska.<br />
<br />
What I wasn't wrong about is it's natural characteristic as a cure for poison ivy (which I suffer greatly from every time I come into contact with it). Sap from the crushed leaves and stems if applied soon after contact can negate or greatly reduce the rash from contact with poison ivy. Just be wary of the berries produced after the flowers are pollinated as they can be quite toxic to humans, especially children.<br />

This one was one of thousands found growing on the edges of Soos Creek in Southern King County, in Kent, Washington.

  • Found almost everywhere in North America (except Louisiana, Alabama, Georgia, South Carolina and Florida) this aggressive native aster has become invasive in parts of China, Japan and Europe. This perfect specimen was found near Soos Creek in Kent, Washington about 20 miles south of Seattle.

  • A close-up image of the very rare Cascade Red Fox, a subspecies found in the alpine and subalpine regions of many of the volcanic mountains of the Cascades in the Pacific Northwest. This beautiful subspecies is often nearly all black with silver or gray, and once flourished over much of Northwestern North America and is facing increasing pressure from climate change, invasive species like coyotes and humans, high-elevation logging and winter recreation sports such as snowmobiling and skiing. Not long before I got this shot, I spent part of a previous evening watching two pure-black kits (baby foxes) stalking and pouncing on each other in the snow in pure delight up in near the tree line on Mount Rainier.
