Nature reserves attract humans, but at a cost to biodiversity, says study

CAPTION: During periods of excessive drought, local herders in northern Kenya, including the woman shown here at the Samburu National Reserve, are allowed access to protected areas, where livestock will share scarce water with elephants and other wildlife. During two recent droughts, 60 percent of cattle in this primarily pastoral region died, but herding communities on the borders of Samburu and Buffalo Springs National Reserves fared far better as a result of their legal access to parklands.

Sudden Oak Death pathogen is evolving, says new study that reconstructs the epidemic

CAPTION: These tanoaks were killed by the Sudden Oak Death pathogen on Mount Tamalpais, near one of the sites where the exotic pathogen was first introduced in California. Infected ornamental plants were found to be the most likely source of the introduction.

CAPTION: Up to 100 percent of adult tanoaks have been killed by the Sudden Oak Death pathogen in many sites around the Big Sur region (Monterey County). Despite the extreme severity of the disease, the pathogen was introduced in the Big Sur region well after its introduction in Santa Cruz and Marin counties. Unfortunately, climatic conditions favorable to the pathogen have led to very rapid spread of SOD in this area.
