Video: Smithsonian horticulturalist Janet Draper discusses the pollination of the pelican flower

Flowers are usually associated with butterflies, but not the Dutchman’s Pipe (Aristolochia grandiflora). This deciduous vine, native to Brazil, has large flowers that emit an odor of decaying flesh, which attracts flies and beetles.

Study backs restoring green buffers along streams to reduce Chesapeake Bay pollution

Current plans to protect the Chesapeake Bay include planting trees along hundreds of miles of streams that empty into the Bay. This study provides realistic limits for how much these buffers might further reduce nitrate pollution, and it helps identify where buffer restoration can offer the greatest additional nitrate removal.

Angelenos are used to looking up Heal the Bay's annual beach water quality report card each May as we search out the cleanest places to swim and surf.

Now, the environmental advocacy group is focusing on a new target — the often polluted water that flows into the ocean from the mountains and across the L.A. Basin.

In a first-ever report, it concludes the managers of 12 watersheds from Malibu to Long Beach are making too little progress toward cleaning up this major source of pollution in the Pacific.
