After having been extirpated to near extinction at the turn of the century, northern elephant seals (Mirounga angustirostris) have re-established breeding colonies on isolated beaches and offshore islands along the California coast since the 1950's (Stewart et al. 1994). In 1981, the first northern elephant seal birth was recorded at an isolated pocket beach at the Point Reyes National Seashore (PORE; Allen et al. 1989).

Northern elephant seals (Mirounga angustirostris) established a breeding population at Point Reyes National Seashore (PORE) in 1981 and since then the colony has grown steadily (Allen et al. 1989). Currently, elephant seals breed at numerous sites within PORE, with four primary sites located at Drake's Beach (DB), Point Reyes Headland (PRH), South Beach (SB), and Chimney Rock Loop (CRL). PORE began to monitor the elephant seal population to contribute to the understanding of population changes and management needs, and to develop research, interpretation and enforcement strategies. A pinniped monitoring protocol was developed in 2009 and includes objectives for monitoring elephant seals to determine trends population growth and productivity.

The information presented in this report is a summary of the harbor seal data collected at Point Reyes National Seashore and Golden Gate National Recreation Area during the 2007 breeding and molting seasons, March-July. Summary data collected as part of a region-wide survey effort, including adjacent areas (San Francisco Bay, San Mateo County and Sonoma County) where NPS surveys were conducted in conjunction with other agencies and organizations for 2007, are also presented. This report is not intended to analyze long-term trends in the harbor seal data set, which are more appropriately investigated at five year intervals (i.e. Allen et al. 2004). Furthermore, this document is not intended to report on or analyze data specific to NPS management issues related to harbor seals.

Download Building Resilience to Climate Change Book in PDF, ePub and Kindle
With climate change now a certainty, the question is how much change there will be and what can be done about it. One of the answers is through adaptation. Many of the lessons that are being learned in adaptation are from success stories from the field. This publication contains eleven case studies covering different ecosystems and regions around the world. Its aim is to summarize some current applications of the Ecosystem-Based Adaptation concept and its tools used around the world, and also draw lessons from experiences in conservation adaptation.

Download Mammals and Birds as Bioindicators of Trace Element Contaminations in Terrestrial Environments Book in PDF, ePub and Kindle
The population explosion that began in the 1960s has been accompanied by a decrease in the quality of the natural environment, e.g. pollution of the air, water and soil with essential and toxic trace elements. Numerous poisonings of people and animals with highly toxic anthropogenic Hg and Cd in the 20th century prompted the creation of the abiotic environment, mainly in developed countries. However, the system is insufficient for long-term exposure to low concentrations of various substances that are mainly ingested through food and water. This problem could be addressed by the monitoring of sentinels – organisms that accumulate trace elements and as such reflect the rate and degree of environmental pollution. Usually these are long-lived vertebrates – herbivorous, omnivorous and carnivorous birds and mammals, especially game species. This book describes the responses of the sentinels most commonly used in ecotoxicological studies to 17 trace elements.
