Save Point Molate, a Natural Treasure by ilana debare

oint Molate in North Richmond may be the most important P Bay development battle you’ve never heard of. These 413 acres include the last undeveloped, unprotected headland along the Bay. The point’s hillsides and shores are home to 600 plant and animal species, including over 140 bird species and four active Osprey nests. They also host Ohlone sacred sites and the Bay’s most pristine eelgrass bed. And they’re on track to be turned into luxury housing.

G olden Gate Audubon Launches Climate Watch Surveys by david robinson

ational Audubon’s landmark 2018 report brought the dangers n of climate change home to birders. The sobering news was that nearly two-thirds of North American birds—389 species—are at risk if global temperatures rise by three degrees Celsius. But the report offered hope too: Limiting temperature rise to 1.5°C would help over three-fourths of the most vulnerable species. Spurred by this and other studies, Golden Gate Audubon Society has begun to focus on climate change in addition to our longstand- ing local conservation work. Many of our most important efforts will involve advocacy. Our latest initiative, though, involves com- munity science: Taking part in National Audubon’s twice-yearly Climate Watch.

POINT MOLATE from page 1

The City of Richmond has contracted with a Southern California developer to build over 1,400 upscale townhouses at Point Molate, which occupies 1.4 miles of Bay shoreline north of the Richmond-San Rafael Bridge. Richmond citizens voted down a previ- ous plan to turn Point Molate into a casino. The current City Council majority opposes the luxury-housing plan. The Point Molate Alliance, a grassroots citizens group, has been fighting the development for years. Yet this ill-conceived scheme barrels on—fueled by outdated notions of shoreline management and a series of convoluted,

They also pop- ulate Central and South America, breeding as far south as Chile and Argentina. Not known to migrate, White-tailed Kites appear to be nomadic and to follow their main food supply (voles and house mice) when scarcity occurs. Highly social, these kites roost communally during the non- breeding season, with up to 100 birds clustering in a stand of trees. They perform spectacular mid-air courtship displays in which males offer prey to females, who approach and turn upside-down to grasp the offering. Pairs stay together during the breeding season and sometimes pair up in successive seasons. While not particularly ter- ritorial, White-tailed Kites may challenge invading kites, locking
