Yes, decaying vegetation underwater in a swamp will produce methane, also known as swamp gas.
Swamp vapor, or swamp gas, is methane gas. The methane gas is formed when the organic material in a swamp decays in the absence of air.
Methane is made by living things and is also a fossil fuel. Swamp gas is a good example, the biologic action of bacteria in the swamp causes Methane to be released to the surface, this gas can and has been burnt at the source. Other sources are animal (and human) Flatulence, oil wells etc.
Swamp gas is composed of multiple gases but is primarily methane.

Methane is separated from cow dung by subjecting the cow dung to a heat source. From there, methane can be used as an energy source for generating electricity on a farm.

"Swamp gas" usually applies to volatile chemicals released from swamps or bogs when organic material ferments (rots). The chief component is usually methane (CH4), which is normally colorless but can suspend liquid particles (mostly water) to appear as a cloud. Swamp gas from landfills is now sometimes used as natural gas (biogas) by removing contaminants from the methane.
Quite literally, Swamp gas from decaying fecal products. This is funny as some people have explained away UFO"s as swamp gas, which is actually Methane.
An organism that uses methane as an energy source is called a methanotroph. Methanotrophs combine oxygen and methane to produce formaldehyde which is metabolized via the RuMP pathway.
Methane is natural gas, CH4. It's commonly formed by the decomposition of organic materials, and is a component of "swamp gas". Methane is found just about everywhere. Another contributor wrote: I can't find that town in my Atlas anywhere.
Organic matter (mainly/mostly dead plants).
Methane is not a direct source of bacteria, bacteria does not spontaneously generate from methane alone. However, some archebacteria (a type of bacteria) called methogens use methane in metabolic processes in the cell. (Metabolic processes are processes the bacteria uses to get energy from other things)
