A lot of that mass is stored in their underground corms, which will carry them through the other 10 months of the year, until they make a run for the sun again. The corms and plants pack on weight while they can and one study found that trout lilies increase their mass 250 percent in 12 days, with a 450 percent increase in the course of the two month growing season. These small flowers are produced seven years after the seed is set, from corms that can be as deep as 15 inches underground. They are good examples of the non- ephemeral nature of spring ephemerals.

Only half of one percent of the plants in a trout lily patch will flower in a given year, and some never will. The brown speckled leathery green leaves under the yellow blooms are reminiscent of the side of a trout, hence the name. Yellow bell flowers grow on a six-inch-tall stalks and nod toward the earth, toward their origins. One of the most common and wide spread of the spring ephemerals are trout lilies, who give us the first specks of color after the white and brown winter clears.

They fill the void between snow cover and canopy, when sunlight reaches the forest floor and warms the soil, and they entrepreneurially take advantage of these bright conditions to make and store food for the rest of the year and engage in energetically expensive reproduction. Niches are often defined by physical space, a way to plug into an ecological gap not filled by anyone else. They are botanical bad asses, who strategize to fill a temporal niche. While we may only see them during their short rush for sun, in the window between snow cover and canopy leaf out, the reality of these plants is very different from our imposed assumptions. The spring ephemerals are emerging.Įphemeral is an interesting term for these beings, conjuring up a fleeting frailty, and from our human perspective, they are – but only just as we are fleetingly frail when our specks of lives are viewed from a geologic perspective. Army Corps District office or EPA regional office.The energy that was just beneath the surface, as winter took its final stand, is starting to erupt. To find out whether specific activities are exempt, contact your local U.S. Planting different crops as part of an established rotation, such as soybeans to rice, is exempt.ĭischarges associated with ongoing rotations of rice and crawfish production are exempt. Introduction of a new cultivation technique such as discing between crop rows for weed control may be a new farming activity, but because the farm operation is ongoing, the activity is exempt from permit requirements under Section 404. ExamplesĪctivities that bring a wetland into farm production where the wetland has not previously been used for farming are not considered part of an established operation, and therefore require a permit. In general, any discharge of dredged or fill material associated with an activity that converts a wetland to upland is not exempt and requires a Section 404 permit.

Both conditions must be met in order for the activity to be considered non-exempt. If an activity listed above as exempt represents a new use of the water, and the activity would result in a reduction in reach or impairment of flow or circulation of regulated waters, including wetlands, the activity is not exempt. This exemption pertains to "normal farming" and harvesting activities that are part of an established, ongoing farming or forestry operation. You do not generally need a permit under Section 404 if your discharges of dredged or fill material are associated with normal farming, ranching, or silviculture activities such as plowing, cultivating, minor drainage, and harvesting for the production of food, fiber, and forest products or upland soil and water conservation practices. Maintenance of structures such as dams, dikes, and levees Maintenance (but not construction) of drainage ditchesĬonstruction and maintenance of irrigation ditchesĬonstruction and maintenance of farm or stock pondsĬonstruction and maintenance of farm and forest roads, in accordance with best management practices Activities Exempt under the Clean Water Act, Section 404(f)(1)Įstablished (ongoing) farming, ranching, and silviculture activities such as plowing, seeding, cultivating, minor drainage, harvesting for the production of food, fiber, and forest products, or upland soil and water conservation practices However, certain activities are exempt from permit requirements under Section 404(f)(1). In general, Section 404 of the Clean Water Act requires permits for the discharge of dredged or fill material into waters of the United States, including wetlands.
