Salt Cedar, Tamarisk ramosissima

Impacts:

  • Aggressive plant that can quickly create a monoculture along streams
  • Uses very large amounts of groundwater - a single plant is capable of transpiring over 200 gallons of water per day!
  • Displaces native riparian plants and alters animal habitats
  • Native birds and animals generally will not eat the seeds or leaves
  • The plant prevents native plant species from re-establishing by exuding salts from the leaves which increase the salinity of the surrounding soil
  • Can choke waterways, causing flooding and impeding flow
  • Very difficult and expensive to control once established - a single plant can produce as many as 500,000 seeds that can remain viable for up to one year. The plant is also able to regenerate through the root system and produce new shoots if top growth has been removed
