37. Poisonous Plants
Plant Identification
The old saying "Leaves of three, Let it be!" is a helpful reminder for
identifying poison ivy and oak, but not poison sumac which usually has
clusters of 7-13 leaves.
Even poison ivy and poison oak may have more than three leaves and
their form may vary greatly depending upon the exact species
encountered, the local environment, and the season.
Being able to identify local varieties of these poisonous plants
throughout the seasons and differentiating them from common
nonpoisonous look-a-likes are the major keys to avoiding exposure.
38. Poison Ivy
Eastern poison ivy is typically a hairy, ropelike vine with three
shiny green (or red in the fall) leaves budding from one small
stem
Western poison ivy is typically a low shrub with three leaves
that does not form a climbing vine
May have yellow or green flowers and white to green-yellow
or amber berries
39. Poison Oak
Typically a shrub with leaves of three, similar to poison ivy
Pacific poison oak may be vine-like
May have yellow or green flowers and clusters of green-
yellow or white berries
40. Poison Sumac
Woody shrub that has stems that contain 7-13 leaves arranged in
pairs
May have glossy, pale yellow, or cream-colored berries
41. Poisonous Plants
Exposure
Workers may become exposed to urushiol through:
Direct contact with the plant
Indirect contact, such as touching tools, livestock, or clothing
that have urushiol on them
Inhalation of particles containing urushiol from burning plants
Symptoms
Signs or symptoms associated with dermal contact with
poisonous plants may include:
Red rash within a few days of contact
Possible bumps, patches, streaking, or weeping blisters (blister
fluids are not contagious)
Swelling & Itching

Recommendations for Protecting Workers
Employers should protect their workers from poisonous
plants by training them about:
Their risk of exposure to poisonous plants
How to identify poisonous plants
How to prevent exposure to poisonous plants
What they should do if they are exposed to poisonous
plants
43. Poisonous Plants
Prevention
Workers can prevent contact with poisonous plants by taking these steps:
Wear long sleeves, long pants, boots, and gloves.
Wash exposed clothing separately in hot water with detergent.
Barrier skin creams, such as a lotion containing bentoquatum, may offer
some protection before contact.
Barrier creams should be washed off and reapplied twice a day.
After use, clean tools with rubbing alcohol (isopropanol or isopropyl
alcohol) or soap and lots of water. Urushiol can remain active on the
surface of objects for up to 5 years.
Wear disposable gloves during this process.
Do not burn plants that may be poison ivy, poison oak, or poison sumac.
Inhaling smoke from burning plants can cause severe allergic respiratory problems.
44. Poisonous Plants
First Aid
Workers who have come in contact with poisonous plants
should:
Immediately rinse skin with rubbing alcohol, specialized
poison plant washes, degreasing soap (such as
dishwashing soap) or detergent, and lots of water.
Rinse frequently so that wash solutions do not dry on the skin and
further spread the urushiol.
Scrub under nails with a brush.
Apply wet compresses, calamine lotion, or hydrocortisone
cream to the skin to reduce itching and blistering.
Follow the directions on any creams and lotions. Do not apply to
broken skin, such as open blisters.
Oatmeal baths may relieve itching.
45. First Aid cont…
An antihistamine such as diphenhydramine
(Benadryl) can be taken to help relieve itching.
Follow directions on the package.
Drowsiness may occur.
If children come in contact with work clothing
contaminated with urushiol, a pediatrician should
be contacted to determine appropriate dosage.
In severe cases or if the rash is on the face or
genitals, seek professional medical attention.
Call 911 or go to a hospital emergency room if the
worker is suffering a severe allergic reaction, such
as swelling or difficulty breathing, or has had a
severe reaction in the past.

Description
This large-bodied venomous snake is distinguished by a series of "diamonds" that run almost the entire length of the body; two distinctive light stripes on each side of the face that angle diagonally (with one stripe in front of and one stripe behind each eye); a tail that is boldly banded in alternating black and white; and, of course, a rattle.
Western Diamond-backed Rattlesnakes from Arkansas may not have "diamonds" that are clearly marked. The snakes may rather appear "dusty", with a spattering of tans, rusts, and creams.
As with all of the pit vipers that occur in Arkansas, the Western Diamond-backed Rattlesnake has a boxy-shaped head, heat-sensing pits, and vertical pupils.
In terms of bulk, this is Arkansas's largest snake.
This species is also known as the Coon-Tail Rattler, D'back, or simply Atrox.
Habitats
This snake has typically been associated with rugged, rocky, and remote areas. Undisturbed and exposed rocky South- and West-facing slopes that catch a lot of sun may be vital for this snake's continued existence in Arkansas. These areas are especially important to gravid females, which require very hot temperatures for their developing eggs.
Habits and Life History
The habits and life history of the Western Diamond-backed Rattlesnake is similar to that of the Timber Rattlesnake. Precious little is currently known about Western Diamond-backed Rattlesnakes in the state.
It is likely Western Diamond-backed Rattlesnakes emerge from hibernation in mid- to late Spring. After basking near their den sites for a few days, they will disperse to forage throughout the summer.
The pattern of large movements may be quite predictable for individual snakes, as they may repeatedly hunt the same areas over and over.
Toward the end of summer, males will begin making large straight-line movements in search of females with which to mate. After a female has been located, a male may protect his claim from other suitors. He may even coil directly on top of her in order to hide her from other males. After they have copulated from one time to several times, he will seek out another female.
During this same time, gravid females will be selecting hot, rocky microhabitats. The developing eggs require a significantly higher body temperature of the females than ambient air temperature. The young, which are born in the Fall, are encased in a shell-less egg. They cut through the outer egg membrane using a special egg tooth and emerge within a couple of minutes after being laid. They will stay very near, or even on top of, their mother for several days.
Description
This large-bodied venomous snake is fairly variable in coloring and patterning. Basic colors may range from true black, to brown, to dark olive, to olive-green. A Cottonmouth that is dry and dusty may even appear gray or silverish. Patterning is also variable, with juveniles almost always having a more clearly defined pattern than adults. This patterning closely resembles that of a Copperhead, with the darker bands widening toward the belly and narrowing at the back.
The head of a Cottonmouth is "boxy"; rather than the more roundish shape of a nonvenomous watersnake head. The cheek is tannish to whitish, usually with a dominant white stripe running from just under the eye to the corner of the mouth. The eyes are shielded from the top by scales, so that the eyes cannot be seen from directly above the snake (the eyes of nonvenomous watersnakes are visible from above).
As with the young of Copperheads and Pygmy Rattlesnakes, Cottonmouth young also have brightly-tipped tails of neon yellow or green.
This species is known by several other common names, including Gaper, Lowland Moccasin, Trapjaw, and Water Moccasin. (Some locals in Arkansas will call any snake seen in the water a water moccasin regardless of the species.)
Habitats
Although denning sites may be some distance from water, this snake is almost exclusively encountered in or around bodies of water. The source of water may be anything from a clear mountain stream to a large lake. Water sources that are slower moving, do not dry up during the summer, and have banks that are thick and lush with vegetation seem to have higher populations of Cottonmouth. My personal experience is that Cottonmouth are very rarely found at cattle ponds (although these ponds do often have high numbers of nonvenomous watersnakes).
Habits and Life History
Cottonmouth often den quite a distance from water, and may actually spend a couple of weeks near their den site basking before moving to a water source.
The typical day for a Cottonmouth begins with a long basking period, that may last the entire day. Favorite basking sites are on logs, tree snags, or in the vegetation along the bank of a water source. If the day is not suitable for basking, a Cottonmouth will usually "hole up" under a rock, in thick brush, or even tucked up under the root system along the water's edge.
After a long period of warming up during the day, a Cottonmouth may spend most of the night actively hunting for food, even in relatively chilly water.
Cottonmouth activity heightens as the days of summer warm and the water temperatures rise. This time of year also coincides with mating season.
This large-bodied venomous snake is distinguished by a rather plain, tan or brown head; dark, bold crossbands; a rust-colored stripe down the backbone; a black, "velvety" tail; and, of course, a large rattle.
The background coloration may vary from a dark slate-gray, to a silverish gray, to tan, to brown. Even individuals within the same population may look strikingly different from one another in this regard.
As with all of the pit vipers that occur in Arkansas, the Timber Rattlesnake has a boxy-shaped head, heat-sensing pits, and vertical pupils.
The young of a Timber Rattlesnake may look in many ways similar to a Pygmy Rattlesnake. However, the Pygmy Rattlesnake has a strongly patterned head and relatively smaller rattle in comparison to body size.
This species is also known as the Canebrake Rattlesnake or Velvet-Tail Rattler.
Habitats
This snake has typically been associated with rugged, rocky, remote, and heavily forested areas. However, after Timber Rattlesnakes disband from their den sites in the Spring, they may utilize a variety of habitats, including cedar glades, grassy fields, and areas of sumac and thick brush.
Habits and Life History
In Arkansas, Timber Rattlesnakes typically hibernate in relatively fewer numbers per den location than in other parts of their range (especially to the north). Den sites may house an estimated 1-20 adult snakes. These locations are usually West- or South-facing bluffs or other rocky outcroppings. Animal burrows may also be used as dens.
Emergence from hibernation occurs in mid-Spring
Description
This medium-sized venomous snake is identified by its strong, hourglass-shaped dark cross-bands. The head may have a distinctive copperish color, thus the name "Copperhead". The top of the head will also show two rather distinct dots. The tail of an adult Copperhead will be black with bright white flecks. As with all of the Pit Vipers found in the state, the Copperhead has heat-sensing pits. These occur between the eyes and nostrils. The pupils (as with all Pit Vipers in the state) are vertical, like a cat's.
Two subspecies, the Southern Copperhead (A. c. contortrix) and Osage Copperhead (A. c. phaeogaster), intergrade in the state.
Juveniles look similar to adults, but have a bright neon yellow tail.
This species is also known as the Highland Moccasin or Upland Moccasin.
Habitats
While this relatively common snake may be found pretty much anywhere in the state, a few of its favorite places seem to be old abandoned barns (and other similar structures), rock piles, and rugged, rocky woodlands.
Habits and Life History
Copperheads typically den in relatively damp and shaded rock crevices (when compared to Timber Rattlesnake den sites), but other denning sites, such as animal burrows, may also be used. They emerge from hibernation in mid to late April and quickly disperse in search of prey.
Human encounters with this snake become more commonplace during the very hottest part of the summer for two primary reasons. One reason is that this is the mating season and males are moving around much more in search of females. The second reason is that it appears this is a time of year when Copperheads become increasingly more active in their pursuit of prey. In fact, they may even congregate in areas where large numbers of Cicadas are emerging; even pursuing them into trees! Dusk and dawn seems to be when these snakes are on the move the most.
A female who is gravid (from insemination the year before) will seek out a suitable spot to bask and may move very little for an entire month. She will give birth to live young in late summer, but it may take up to a week after birth for her and her babies to disperse (probably back toward a suitable denning site).
This small venomous rattlesnake is identified by the reddish stripe down the backbone coupled with black cross-bands. The general background color is slate-grey.
The top of the head is distinctly patterned with a spear-tip pattern. This feature helps to quickly distinguish it from a baby Timber Rattlesnake, which can look similar but has a rather plainly-patterned head.
As with all of the pit vipers found in the state, the Pygmy Rattlesnake has heat-sensing pits. These occur between the eyes and nostrils, but are difficult to see in the species because they blend with the patterning.
The tail is tipped with a very small rattle that produces a sound reminiscent of a small insect buzzing. The sound carries only a few feet. In the young, the tail (just prior to the rattle itself) is a bright neon yellow or green.
This species is also known as the Ground Rattler. To those with some familiarity, they are simply Pigs.
Habitats
This species seems to prefer wooded habitat and cedar glades. Prime areas are brush piles and edge habitats where forest meets field.
This small, shiny, slender venomous snake is distinguished by its pattern of bold and clearly-defined black, red, and yellow bands. The red bands are spotted with black dots. There are several variations to the saying "Red touches yellow, kill a fellow. Red touches black, venom lack." While it is true that the red and yellow bands of this species do touch, childish rhymes should not be trusted for proper identification. For example, outside of North America the "rules" of this rhyme are broken by numerous Coralsnake species and their mimics.
The snout of this species is completely black and blunt. Its eyes are dark and beady. Similar-looking nonvenomous snakes typically have a cream-colored or red snout and larger, more prominent eyes.
Unlike the other venomous snakes in Arkansas, Coralsnakes are not Pit Vipers. Thus, they lack heat-sensing pits, vertical pupils, stout bodies, and "diamond-shaped" heads (all traits that are used--or more often misused--by laypersons attempting to identify a snake as venomous or not). This species, in fact, is an Elapid. Its closest relatives are Cobras, Mambas, and Seasnakes.
This snake is also known as the "Kill a Fellow" Snake or Tricolored Snake.
Habitats
This species of snake is fossorial; spending the vast majority of the time buried in the soil, under leaf litter, or perhaps in rotten logs. It is secretive and rarely seen exposed, despite the fact that it is largely diurnal (active during the day).
