Life in the Wetlands
In the low-lying, water-saturated areas of Houston-like ditches, bogs, swamps, and marshes a rich and unique ecosystem thrives. These wetland habitats are home to moisture-loving native plants such as pickerelweed, spatterdock, buttonbush, swamp milkweed, and willow. Amphibians such as frogs and toads, and invertebrates such as dragonflies and damselflies rely on these wet conditions to complete their lifecycle.
Temporary wetlands that fill up with water from heavy rainfall, may form vernal pools, which dry up during dryer, warmer months. In the cultivated landscape, gardeners can turn low-lying soggy areas into Rain Gardens which are designed to collect and absorb rainwater runoff. These vibrant features use native plants that thrive in wet conditions to filter pollution from stormwater runoff and absorb excess water.

Protecting Irises of Texas
Louisiana irises and native Texas irises are the focus of important conservation efforts of the Species Preservation Project of the Society for Louisiana Irises. This initiative works to protect and restore wild populations of these beautiful, water-loving irises by preserving their natural habitats and encouraging responsible cultivation. There are several varieties of Texas Louisiana Iris in this bog that have been relocated from Harris and surrounding counties due to agricultural or industrial development.
