NOAA designates critical habitat for black abalone

27.10.2011
NOAA's Fisheries Service today filed with the Federal Register a final rule that identifies black abalone critical habitat along the California coast.

In February 2009, black abalone was listed as endangered under the Endangered Species Act, and the Act requires critical habitat be designated, to the maximum extent prudent and determinable, whenever a species is listed for protection.

Once areas are designated as critical habitat, federal projects or permits and projects with federal funding are required to ensure their actions do not adversely modify the animal's habitat. Designating critical habitat does not affect citizens engaged in activities on private land that do not involve a federal agency.

Since the 1980s, the black abalone population has plummeted primarily from a bacterial disease known as withering syndrome. The impacts of withering syndrome may have been worsened by the warming of coastal waters from long-and-short-term changes in climate or from power plants' discharge of warm water. Other causes that likely contributed to the decline in black abalone populations are historical overfishing and poaching.

Black abalone once existed in intertidal waters from the northernmost reaches of California to the southern tip of the Baja peninsula in Mexico. The edible marine snail was harvested from the mid-1800s, and peaked in the 1970s as a commercial fishery in California. Today, the species is rarely found north of San Francisco or much farther south than the California-Mexico border.

Using agency data and information provided by the public, NOAA's Fisheries Service designated critical habitat for black abalone along the California coast to include rocky habitats, and the coastal marine waters above the benthos from the mean higher high water (MHHW) line, or average high tide, to a depth of six meters (approximately 20 feet) in the following areas (see attached map):

From Del Mar Landing Ecological Reserve to Point Bonita.

From the southern point at the mouth of San Francisco Bay to Natural Bridges State Beach.

From Pacific Grove to Cayucos.

From Montaña de Oro State Park to just south of Government Point.

Palos Verdes Peninsula from the Palos Verdes/Torrance border to Los Angeles Harbor.

The circumference of: the Farallon Islands; Año Nuevo Island; San Miguel Island; Santa Rosa Island; Santa Cruz Island; Anacapa Island; Santa Barbara Island; and Santa Catalina Island.

NOAA's Fisheries Service excluded the area of rocky habitat from Corona Del Mar State Beach to Dana Point from the designation, because the economic benefits of exclusion outweigh the benefits of inclusion, and the exclusion will not result in the extinction of the species. It was also determined that San Clemente Island and San Nicolas Island were no longer eligible for designation due to the development of integrated natural resources management plans that provide benefits to black abalone.

Im Focus: Powerful IT security for the car of the future – research alliance develops new approaches

The more electronics steer, accelerate and brake cars, the more important it is to protect them against cyber-attacks. That is why 15 partners from industry and academia will work together over the next three years on new approaches to IT security in self-driving cars. The joint project goes by the name Security For Connected, Autonomous Cars (SecForCARs) and has funding of €7.2 million from the German Federal Ministry of Education and Research. Infineon is leading the project.

Vehicles already offer diverse communication interfaces and more and more automated functions, such as distance and lane-keeping assist systems. At the same...

Im Focus: Molecular switch will facilitate the development of pioneering electro-optical devices

A research team led by physicists at the Technical University of Munich (TUM) has developed molecular nanoswitches that can be toggled between two structurally different states using an applied voltage. They can serve as the basis for a pioneering class of devices that could replace silicon-based components with organic molecules.

The development of new electronic technologies drives the incessant reduction of functional component sizes. In the context of an international collaborative...

At the LASYS 2018, from June 5th to 7th, the Laser Zentrum Hannover e.V. (LZH) will be showcasing processes for the laser material processing of tomorrow in hall 4 at stand 4E75. With blown bomb shells the LZH will present first results of a research project on civil security.

At this year's LASYS, the LZH will exhibit light-based processes such as cutting, welding, ablation and structuring as well as additive manufacturing for...

Im Focus: Self-illuminating pixels for a new display generation

There are videos on the internet that can make one marvel at technology. For example, a smartphone is casually bent around the arm or a thin-film display is rolled in all directions and with almost every diameter. From the user's point of view, this looks fantastic. From a professional point of view, however, the question arises: Is that already possible?

At Display Week 2018, scientists from the Fraunhofer Institute for Applied Polymer Research IAP will be demonstrating today’s technological possibilities and...
