Classification. Other classification systems exist however. Cowardin (1979) recognizes the following five major wetland classifications: marine, estuarine, lacustrine, riverine, and palustrine. Marine and estuarine wetlands are associated with the ocean and include coastal wetlands, such as tidal marshes. Lacustrine wetlands are associated with lakes, while riverine wetlands are found along rivers and streams. Palustrine wetlands may be isolated or connected wet areas and include marshes, swamps, and bogs.

Spinal stenosis is also often seen in patients with lumbar spine arthritis. As arthritis progresses, nerves become pinched, leading to symptoms of spinal stenosis. These symptoms may include leg pain, numbness, tingling, and difficulty walking.
