CharacteristicsSpringsPeatlands, including fens (groundwater dependent)
Other wetlands (groundwater dependent)
HydrologyCompletely groundwater dependent
Minerotrophic; always groundwater dependent
Minerotrophic; depend on groundwater, precipitation, and sometimes stream inflow
Water table positionAt ground surface or, for artesian, a piezometric surface above the ground surface
At or slightly below surface, or piezometric surface above the ground
Above or below ground surface; can fluctuate dramatically; can have periodic standing water
Soils and peat or muck depths
Mostly mineral soils; sometimes a small accumulation of peat
Accumulation of peat or muck up to several meters; little or no mineral soil within plant-rooting zone for fens
Usually little or no peat or muck accumulation; sometimes wood-rich peat
Redox conditionsaOxic to anoxic depending on geochemistry and residence time of water in aquifer
Anoxic slightly below the surface, leading to the accumulation of peat or muck
Temporary soil anoxia during times of high water table or standing water
Water movement within GDEs
Standing or flowing waterSlow to imperceptible flow on surface
Periodic standing or flowing water
Table 3.—Important GDE characteristics and the GDE types covered by this field guide.
a Redox (short for REDuction-OXidation) conditions describe a key chemical characteristic in hydrologic systems that controls the availability of many elements and the propensity of the system to support the accumulation of organic matter, such as peat and muck. At the ground surface, redox conditions are often controlled by the availability of oxygen.

�In case of a bite or sting, watch subject closely for any allergic reaction. Call 911 or local emergency number and evacuate immediately if any reaction away from injury site is observed.
c. Branches striking eyes �Keep a safe distance from partner.
�Wear protective eyewear.
d. Crossing shallow streams �Always work with a partner when planning stream or river crossings with water depths over the knees. Choose crossing sites with shallow water, slow currents, and gradual slopes. Avoid crossing sites with water over mid-thigh depths or swift current.
�Use pole or walking stick to help maintain balance with three-point support. Move one foot or pole at a time.
�Watch for and avoid large, wet, rounded rocks because they may be slippery.
�Be especially alert to the possibility of one foot becoming entrapped in rocks or branches and current forcing individual off balance and under water.
�Carry a rope or throw rope long enough to reach across the entire width of the crossing.
�Make the crossing one person at a time with one person on the bank at all times. Stretch the safety rope between the person on the bank and the person crossing.
�Logs should be used as last alternative and should be of sufficient size, dry, and algae free.
�Leave vest unbuttoned, remove workbelt from waist, disconnect waist and sternum straps on pack, and be prepared to ditch any equipment if you are unable to recover from a fall.
�Protect feet with proper footwear such as waders. Bring dry socks and footwear to wear during field work and hiking.
�Do not cross streams during unfavorable weather.

5. Use of all-terrain vehicle to travel to the field location
�See “ATV Travel” JHA.
6. Driving FS/GSA vehicles �See “General Driving and 15 Passenger Vans” JHA.
7. Overnight travel �See “Overnight Travel” JHA.
8. Office work �See “Office Work” JHA.
9. Conducting field worka. Use of hand tools such as hand axe, pruning saw, and shovel
�When traversing slopes, carry hand tools on the downhill side.
�Hand axes should always be carried sheathed with leather flap snapped shut.
�Do not carry long handled tools over shoulder, or hatchets unsheathed in belt-loop.
b. Dehydration �Consume (in addition to regular meals) fruit and liquids that replace the loss of carbohydrates and maintain blood sugar levels at normal limits. Drink water regularly. Make sure you carry enough water. Take frequent breaks. Avoid open sunny areas if weather is extreme. Seek shaded areas.
c. Hypothermia �Prevent hypothermia by planning ahead and using your gear to stay warm and dry.

d. Poisonous plants present (e.g., poison ivy)
�Make sure that crew members can identify poisonous plants in their work area.
�Wear gloves and long-sleeve shirts.
�Wash affected area with soap and water as soon as possible or use ivy-off products when water is not available.
�Wash potentially contaminated clothing as soon as possible after returning from the field.
e. Falling branch or tree �Wear hardhat.
�Use extra caution during high-wind events.
f. Insect bites �Use appropriate insect repellent.
�Secure bottom of pant legs to reduce the ability for ticks to access your lower leg.
�Thoroughly examine your body for ticks when returning from field. If a tick is found, fully remove it using tweezers or fingernails. Do not use petroleum or try to burn the tick off. Save the tick for confirmation of Lyme disease. Monitor the area on body where tick was attached, watching for irritation or rash. If rash or flu-like symptoms develop, visit a doctor and inform him or her of tick bite.
g. Sun exposure �Use sun screen on exposed skin to prevent sunburn and skin damage. Know the signs and symptoms of heat exhaustion and heat stroke. Wear sunglasses and use sunscreen. Drink enough water to keep hydrated.
h. Altitude problems �Headache, shortness of breath, trouble sleeping, and dizziness. Drink more water than usual and reduce salty food intake.
i. Waders and wading boots �Only wear waders that are the correct size for your feet and body. Nylon breath-able waders are adaptable to a wide variety of temperatures and conditions, and they are essential. Supportive wading boots are essential and give the traction and support necessary for stream work. Wading boots will be worn any time biological technicians are in streams.

10. Encountering hazardous situationsa. Threatening individuals �Use positive communication and conflict management behaviors in early stages of conflict situations to prevent or diffuse low-level hostile behavior.
�If threatened in any way by members of the public, withdraw and report the incident to your supervisor.
�Always attain the landowner’s permission before entering private property.
b. Illegal activities �Leave the area immediately if you feel unsafe because of illegal activity.
�If an area appears to be used for illegal activities, such as a marijuana garden or methamphetamine lab, leave the area immediately by the same route taken to enter the area.
�Report suspicious activity to your supervisor.
�Always attain the landowner’s permission before entering private property.
c. Wild animals such as black bears, wolves, bison, elk, deer, moose, bobcats, poisionus snakes, feral swine, etc.
�Make noise by talking loudly or using a noisemaker such as a bell or whistle to reduce the chances of surprising an animal.
�Immediately leave the area by backtracking if you encounter any animal that appears injured or sick, or may be feeding, mating, or have young nearby. Report the incident to the proper authorities if the animal acted aggressively without provocation.
�Learn the appropriate actions to take if you are approached by any of the animals that may inhabit your work location. These actions differ depending on the type of animal.
�Learn to identify dangerous animals in your working area and never harrass or provoke wildlife.
�Avoid walking blindly through thick vegetation by using a stick or pole in front of you to part the brush or grass.
�In areas with poisonous snakes, tap the ground in front of you with a pole or stick as you walk to help you see snakes before you get too close.
�Wear snake-proof chaps when appropriate.

d. Domestic animals such as dogs, cattle, swine, etc.
�If an animal is acting aggressive or skittish, stay in the vehicle and wait for the landowner to come outside. Honk your horn if necessary to alert the landowner that you are there.
�Ask landowners over the phone about the location of potentially dangerous domestic animals and request that they be moved or tied up while you are visiting the location, or plan to visit when the animal will not be there.
�Make sure that landowners know when you are working in the area if you believe they may have an aggressive or protective animal.
e. Hazardous materials �Whenever encountering containers of unidentified liquids or powders, stay clear of the site. Do not walk into or touch spilled material. Avoid inhalation of fumes, smoke, and vapors, even if no hazardous materials are known to be involved. Do not assume that gases or vapors are harmless because they do not smell. Odorless gases or vapors may be harmful. Drums may contain toxic materials, leak, and contaminate their immediate surroundings.
�If it is possible to read any labels without risk of contaminating yourself, do so and write the information down. Note location, time of encounter, and any other pertinent information. Then report it to supervisor.
�Likely areas where hazardous materials are encountered include abandoned mine sites, old construction sites, and old homestead sites.
f. Encountering hunters �Plan field work appropriately given area hunting use and seasons.
�Wear blaze orange vest or clothing.
�Ensure landowners know where you will be and when you will be there.
�Inform hunters of where you will be and how long you expect to be there, and find out where they plan to hunt.
�If someone is hunting near your plot and is there first, return at a later date.
