Twitchell Island is the site of an experiment being conducted by the U.S. Geological Survey to study whether growing tules and cattails on the sinking islands of the Sacramento Delta can reverse the soil loss caused by wind, rain and farming.

The plants not only help rebuild the level of the soil, but sequester quite a bit of carbon as well. It is believed that farmers in the delta might be able to make money with so-called "carbon-capture" farming by planting tules and cattails rather than row crops and get paid by companies who need to meet state greenhouse gas limits.
