The grass Tuctoria mucronata, also known as prickly spiralgrass, Solano grass, or Crampton's tuctoria, is a very rare plant. It is an endangered species and can only be found in two counties in northern California. This means it is at high risk of disappearing forever.
What Does Solano Grass Look Like?
Solano grass is a small plant that lives for only one year. Its stems grow low to the ground, reaching up to 12 centimeters (about 5 inches) long. The tips of the stems then turn upwards. Its leaves are 2 to 4 centimeters long. They feel sticky and have a nice smell. In the spring, this grass grows small flower clusters, called inflorescences, that are 1.5 to 6 centimeters long. These clusters have many tiny, crowded spikelets (small parts of the flower).
Where Does Solano Grass Live?
Solano grass is a special plant that grows only in vernal pools. Vernal pools are unique places that fill with water during the wet season (like winter and spring) and then dry up in the summer. This type of habitat is also in danger of disappearing.
Scientists believe Solano grass once grew in parts of the northern Sacramento-San Joaquin Delta. These areas would flood during the wet season, just like vernal pools. However, most of that land has been changed for agriculture (farming). Now, only a few of these plants exist, mostly in Yolo County. It was found in the 1990s at a place called Jepson Prairie Preserve, which works to protect vernal pool habitats. But it might not even be there anymore.
Why Is Solano Grass Endangered?
The main reason Solano grass is almost extinct is because its habitat is being lost. This happens for several reasons:
- Land Development: Areas where the grass grows are being used for buildings and other projects.
- Recreation: Activities like sports or other outdoor fun can disturb the land.
- Farming: Land is being turned into farms, which changes the natural environment. This includes animals grazing, fertilizer runoff, and changes to the natural water flow (hydrology) in the Central Valley.
- Invasive Plants: Invasive plants are plants that are not native to the area and grow very quickly. They can crowd out native grasses like Solano grass. Other native grasses that are also affected include Greene's tuctoria (Tuctoria greenei), Colusa grass (Neostapfia colusana), and several types of Orcuttia grass.
