This Plant Can Burn Your Skin With Its Sap—And It May Be Coming to Your Neighborhood

It's huge, it's extremely dangerous, and it's spreading. The giant hogweed (Heracleum mantegazzianum) contains a corrosive sap that causes severe rashes, third-degree burns, and even permanent blindness if you get the photosensitive chemicals on your skin or in your eyes, Science Alert reports.

The noxious, invasive weed was just identified in Clarke County, Virginia, near the Massey Herbarium at Virginia Tech. That brings the number of states it's been spotted in to 11, including Washington, Oregon, Illinois, Michigan, North Carolina, Pennsylvania, New York, Connecticut, Massachusetts, and Maine. Beyond the U.S., it has taken root all over the world, from the UK to Iceland to Australia.

Similar to the common but slightly less dangerous cow parsnip, giant hogweed is native to Central Asia and was first brought to North America in the early 1990s as an ornamental plant, its unique shape making it popular among gardeners. But it soon became invasive: Once it’s established in an area, it can take up to five years to eradicate a colony.

Now the plant is considered a public health concern. Hogweed can cause a reaction known as phytophotodermatitis when it comes into contact with skin that is subsequently exposed to UV rays—but the effects of hogweed are much more severe. A painful blister can develop within hours and last for months; the exposed skin can remain sensitive to sunlight for years even after the blisters heal.

Hogweed can be difficult to distinguish from the cow parsnip, and the plant is often misidentified. First, check for height: Hogweeds are typically taller than 8 feet, while cow parsnip tends to be 5 to 8 feet tall. Hogweed stems are green with purple specks and coarse white hairs, while parsnip stems are green with fine white hairs. For more tips and photos, check out the New York Department of Environmental Conservation’s guide.

If you see a plant you think might be a giant hogweed, take a few photos and send them to your state's department of agriculture to identify—and whatever you do, don't touch it.

These Nature Posters Show the Most Endangered Animal in Each State

The U.S. has more than 1300 endangered or threatened species, from South Dakota's black-footed ferret to Colorado's Uncompahgre fritillary butterfly to the blue whales that live off the coast of Alaska. These wild animals could disappear if prompt wildlife conservation measures aren't taken, and people are largely to blame. Globally, human activities are the direct cause of 99 percent of threatened animal classifications, according to the Center for Biological Diversity.

Some of these animals may even be in your backyard. A research team commissioned by NetCredit used data from the U.S. Fish and Wildlife Service to highlight the most endangered animal in each state. For this project, "most endangered" refers to the animals that face the greatest risk of extinction. An art director and designer then teamed up to create gorgeous illustrations of each animal.

Since some regions are home to many of the same creatures, a different animal was selected from the shortlist of endangered species in cases where there were duplicates from one state to the next. The goal was to cast light on as many threatened species as possible, including the ones that rarely make headlines.

"We hope this will start a conversation around the fact that it's not just the iconic species we see on nature documentaries that we're at risk of losing forever," the research team said in a statement.

Take the black-footed ferret, for instance. It's the only ferret that's native to North America, but its ranks have dwindled as its main food source—prairie dogs—becomes harder to find. Prairie dog eradication programs and loss of the ferret's habitat (due to farming) are some of the factors to blame. A ferret breeding colony was established in the past, but only 200 to 300 of the animals still remain, rendering them critically endangered.

The West Coast Is Preparing for Another Super Bloom

In spring of 2017, people flocked to Southern California's deserts to see fields of wildflowers brightening the normally sparse terrain. That level of vegetation, also known as a super bloom, is an event that only occurs after winters of heavier-than-average precipitation. Now just two years later, the rare sight is about to return to California's Anza-Borrego desert, the Los Angeles Times reports.

The 2018/2019 winter season was an unusually wet one for California. Between October 1 and the beginning of February, Downtown Los Angeles saw 12.91 inches of rain, which is approximately 167 percent more than the seasonal average. All that precipitation will produce an explosion of color when spring arrives in Anza-Borrego desert three hours southeast of Los Angeles. Experts predict the 2019 super bloom could start as early as late February and last through March.

If the last super bloom is any indication, this year's event will attract crowds of sight-seers. Anywhere from 250,000 to 500,000 people visited the desert to look at and snap pictures of the flowers in 2017. Many local communities were overwhelmed by the influx of tourists, but this time around they know what to expect. Portable toilets will be set up around popular sites, and thousands of maps of showing where the flower fields, gas stations, and toilets are located are ready to be passed out to drivers.

Visitors also have a few things to learn from the past super bloom. Two years ago, foot traffic in places like the Antelope Valley California Poppy Reserve was so heavy that trails had to be closed down to protect delicate flowers from selfie-taking tourists.
