Central California bull kelp forests remained in cooler waters and thus in better condition when the winter swells hit, and a much greater percent survived. Kelp forests occur worldwide throughout temperate and polar coastal oceans. Scientists hope also to try to develop commercial uses of the purple urchins, thus ensuring long-term sustainable harvesting. Spreading rock dust on the ground could pull carbon from the air. Many species reside in kelp forest, it's a very safe environment to live in. Carrie Wilson, (831) 649-7191.

The Gulf of Maine is the latest global hotspot to lose kelp. The persistent warmer sea temperatures stress the kelp forests to the point that growth and reproduction have slowed dramatically and caused damage to remaining fronds and tissue. Sea urchins like kelp - a lot - and, if their populations get too big, they may graze a kelp forest to death; if they remain, they may also inhibit the kelp's ability to grow again in that area.

A 2016 study noted a global average decrease in kelp abundance, with warming waters directly driving some losses. Unfortunately, with the warming and changing ocean conditions in the last few years, scientists have noticed an alarming decline in these once prolific kelp forests. Kelp in some areas of Southern California already had been reduced by 75 percent over the past century due to pollution and overfishing of species that protect kelp ecosystems. Along the north coast, purple urchins are now successfully outcompeting red urchins and abalone. Large aggregations of purple urchins are wiping out kelp forests, creating pink barrens and out-competing other species, such as abalone, for food.

Kelp forests are characterized by extremely high rates of primary productivity, comprise the base of a complex food web, form a three-dimensional structure that provides physical shelter for many inhabitants, have large algal standing stocks within forests, and export substantial biomass as drift algae that support other coastal ecosystems (Graham et al., 2003; In 2007, kelp forests were also discovered in tropical waters near Ecuador..
