Ecosystem card - Herons in the Cattails

Wetlands in California support a wide variety of species. Here, Great Blue Herons (Ardea herodias) hunt among the cattails (Typha latifolia) for Harvest Mice (Reithrodontomys megalotis), bullfrogs (Lithobates catesbeianus), and three spined stickleback (Gasterosteus aculeatus). Herons help natvie species like the stickleback survive by eating invasive bullfrogs. These California Ecosystem illustrations feature threatened, endangered, or endemic species that highlight some unique aspect of California's incredibly diverse habitats. Each card has a short description of the creatures and relationships printed on the back.   Cards are blank inside and locally printed on 100% cotton paper. They measure 6" x 6" square. Envelopes included. Can be mailed with a single USPS First Class stamp.
