Lake Calavera Preserve

The city of Carlsbad will be undertaking some projects at this preserve in the next year including:

  • removal of palm trees along the northern part of the preserve.
  • restoring, with native plants, the area where these trees currently are.
  • adding a portable bathroom near the Calavera dam.

Here are our answers to some questions regarding the Lake Calavera palm removal project.  For more information on pesticide use for the project click here.
