Although none of the "Drosera" species in the United States are federally protected, all are listed as threatened or endangered in some states. Additionally, many of the remaining native populations lie on protected land, such as national parks or wildlife preserves. "Drosera" species are protected by law in many European countries, such as Germany, Austria, Switzerland, the Czech Republic, Finland, Hungary, France, and Bulgaria. Currently, the largest threat in Europe and North America is habitat destruction for development projects, as well as the draining of bogs for agricultural uses and peat harvesting. In many regions, this has led to the extirpation of some species from parts of their former range. Reintroduction of plants into such habitats is usually difficult or impossible, as the ecological needs of certain populations is closely tied to their geographical location. Through increased legal protection of bogs and moors, as well as a concentrated effort to renaturalize such habitats, the threat to these plants' survival might be curbed, although most species would remain endangered. The relatively unimpressive image of these plants, as well as their small, low growth, makes them difficult to protect. As part of the landscape, sundews are often overlooked or not recognized at all.
