<!-- 1. What is a bog? How is it unique? -->
A bog is a wetland formed in cold climates from water obtained only from the atmosphere (rain and snow). There are no other sources of water such as springs, rivers or streams. Because of this bogs are low in mineral nutrients (nutrients are usually washed into a body of water by rivers and streams). A mat of specialized vegetation grows out over the water. As leaves and plants die and fall in the water, decomposition is very slow, which causes the accumulation of organic matter at the bottom called “peat.” Because of this, the water in a bog is acidic and low in oxygen. Methane gas is a by-product of decomposition and can be seen sometimes bubbling up. Species diversity is low due to the harsh environment. They are important for “storing” carbon.

<!-- 2. Where are bogs found? -->
Bogs occur mostly in cold, heavily forested regions of the northern hemisphere north of the 45th parallel. This region is also called the Boreal Zone.

<!-- 4. Name and describe three different types of true bogs. -->
[[File:Blanket_bog.png|thumb|500px|Blanket bog]]
;Blanket Bog or Blanket Mire: This type of bog has extensive peat cover not just covering basin filled with water, but these ‘blankets’ extend past the basin boundaries and cover the ground over large areas including hilltops, slopes and plateaus. Two hundred days of rainfall a year are needed to form these bogs.

[[File:Quaking_bog.png|thumb|500px|Quaking bog]]
;Quaking bog: This type of bog has floating mats of vegetation including, mosses, shrubs and trees. The whole mat shakes when stepped on. Larger movements may cause trees to sway.
{{clear}}


[[File:Raised_bog.png|thumb|500px|Raised bog]]
;Raised Bog: A type of bog in which peat deposits grow above the water level forming domes or ‘raised’ mounds. These mounds may be surrounded by water forming islands. These are sometimes referred to as a Pocosin in the east.

<!-- 5. What is the difference between a bog and fen? What is succession and how do bogs and fens illustrate this process? -->
[[File:Bog succession 1.png|thumb|500px|right]]
[[File:Bog succession 2.png|thumb|500px|right]]
[[File:Bog succession 3.png|thumb|500px|right]]
[[File:Bog succession 4.png|thumb|500px|right]]
Bogs and Fens are both sources of peat and have a floating mat of vegetation. The major difference has to do with the water source. Bogs are closed systems that have no connection to groundwater sources, Fens are open systems that depend on a groundwater source (springs). Fens are less acidic, have more nutrients and support a more diverse community of plants and animals. For a fen, the mat of vegetation is composed of herbs and grasses such as Tussock Grass.

Succession is where one community naturally changes over time eventually being replaced by a different community. Fens and bogs are often found close together and over time, most fens become bogs. Peat builds up and separates the fen from its groundwater supply causing a closed system to form; nutrient levels drop, acidity increases and a bog is formed. Succession of bogs leads to the formation of conifer forests.

<!-- 6. What are some adaptations of bog plants? -->
* Exposed leaves are covered in waxy material, have thick woolly hair-like fibers, or hide their pores in deep pits on the underside to conserve nutrients and to reduce toxins such as iron and manganese.
* Grow low to the ground or have slow stunted growth.
* Survive dramatic temperature differences.
* Live in acid conditions with low nutrients.

<!-- 7. What is Sphagnum Moss and how is it vital to bogs? -->
[[File:Sphagnum.flexuosum.jpg|thumb|250px|''Sphagnum flexuosum'']]
Sphagnum Moss or Peat Moss (Family Sphagnaceae) is a plant that shapes and drives bog chemistry. It has gas-filled cells that help it to float and has amazing absorption properties enabling it to hold many times its own weight in water. It grows from the top and dies just a small distance down the stem. It slowly grows out from shore eventually forming a floating mat of vegetation over any open water resulting in the sun not being able to warm the water below. When new moss forms, the old moss is pushed underwater and decays very slowly into peat. As it slowly decays, tannin and acids are released killing bacteria and removing dissolved oxygen that would otherwise cause decomposition to occur, also turning the water brown. Dead peat moss accumulates until it is many feet deep and eventually, given enough time, will reach ground level below and fill the bog completely. Sphagnum Moss supports a variety of acid loving plants, shrubs and even trees to grow on top of its floating mass over deep water, also called bog forest. When stepped on, the mats shake, tilt and ripple causing even trees to sway. Falling into a bog can be dangerous so it is best to stay on designated boardwalks and trails.

<!-- 8. What are carnivorous plants and what makes them bog specific? Name and describe at least two of them. -->
Carnivorous plants trap animal prey (insects) to make up for the loss of nutrients they cannot obtain from the environment. The traps are modified leaves and may be “active” or “passive” depending on how they catch their prey.
===Pitcher Plant (Passive)===
[[File:Pitcher_Plant_at_Mississippi_Sandhill_Crane_NWR_(5327602495).jpg|thumb|Pitcher Plant at Mississippi Sandhill Crane National Wildlife Refuge]]
These plants form a slippery, colorful cupped leaf, and have a nectar-covered lip to lure insects. When an insect slips and falls in, it is trapped by downward pointing, sharp hairs. It is slowly dissolved in the liquid in the bottom of the cup. There are some insects that thrive in the pitcher plants by having an anti-enzyme that prevents them from being digested by the plant.
{{clear}}

===Sundew (Active)===
[[File:Sundew.jpg|thumb|Sundew]]
Sticky hairs in their leaves attract and hold the insect, and then more sticky hairs fold over it until the insect is trapped and is digested.
{{clear}}

===Bladderwort (Active)===
[[File:UtriculariaVulgarisFlowering.jpg|thumb|Common Bladderwort]]
A group of aquatic flowering plants that grow with no roots. They obtain their nutrition from the water or prey captured in small “bladders”. There are trigger hairs that, when touched, open a trap door and the prey is sucked in when the water rushes in to fill the “bladder” and the door shuts trapping the prey.

<!-- 11. Tell a story about bogs and draw a spiritual lesson. -->
This is one example. You can develop your own story.

“And do not be conformed to this world, but be transformed by the renewing of your mind, that you may prove what is that good and acceptable and perfect will of God.” Romans 12:2 
Pitcher plants (Family Sarraceniaceae) are carnivorous plants, meaning they have unique ways of catching insect prey and digesting them to obtain nutrients otherwise not available in their environment. The plant has large "pitcher" shaped leaves that catch rain water. The "lip" of the leaf is pretty colored, fragrant and slippery. Insects are attracted to this, fall in and are trapped, unable to escape due to sharp, down pointing hairs causing the insect to drown. The plant then digests its catch. This family of plants (nine species here in North America) often inhabit peatlands, bogs, pine barrens and other such habitats that are hostile to most other types of plants. In one species, the leaves can grow to be almost 3 feet tall! Strangely enough, some insects and other small creatures survive and even thrive inside the pitcher plant. They may spend some time there and move on or in some cases, make a permanent home. There is a type of mosquito larvae (Pitcher Plant Mosquito – Wyeomyia smithii ) that lives in the very fluid that consumes other types of insects. This mosquito living in the pitcher plants have special anti-enzymes that prevent them from being digested. The Bible is like these anti-enzymes; we must have God's word as part of our whole being, our lifestyle and full commitment. We live in a crazy, scary world yet we are not part of this world. We are only passing through. We are not to be consumed by the things and desires this world has to offer for they result in death, just like insects that fall into the pitcher plant and are digested because they do not have the anti-enzyme. God's word must be written in our hearts and minds. May we encourage each other to become filled with these spiritual "anti-enzymes". (Beckermeyer) (Johnson & Worley, 1985)
