  • Innovative Strategies to Apply Water Quality Criteria for Bacteria: A 50-State Survey of EPA-Approved Approaches for Freshwaters

    ABSTRACTSection 101 of the Clean Water Act requires recreational activities to be protected when and where they occur. States, which have adopted a wide variety of strategies to meet this obligation, have one or more formal use classifications to recognize different types of recreational activities. Most states have developed narrative or numeric water quality criteria to limit pathogen pollution ...

  • A study of the compatibility of habitat and water quality enhancement objectives in urban wetlands of southern California, USA

    With the rising urbanization of the coastal watersheds of California, requirements for control of urban runoff have created demand for treatment wetlands to improve surface water quality and attenuate storm flows. Concurrent with this need, significant wetland and riparian habitat have been lost. Pressure is mounting to restore, enhance, and create wetlands with multiple objectives (i.e., habitat ...

  • National Occupational Standards for Environmental Monitors - CORE NOS

    Environmental monitors (EMs) are individuals who observe the environment and the impacts of human and industrial activities, and communicate this information to various stakeholders. In this way, they may help to mitigate negative environmental impacts.

  • Developing a National Tiger Action Plan for the Union of Myanmar

    Abstract  A century ago, tigers were considered pests in Myanmar. Hunters claimed thousands, yet populations persisted. In the past century, because of habitat loss and prey depletion, coupled with the recent demand for traditional medicines, tiger populations have been reduced to a few hundred individuals. As a first step toward long-term planning for tigers, and to guide efforts to ...

  • Double-observer approach to estimating egg mass abundance of pool-breeding amphibians

    Abstract  Interest in seasonally flooded pools, and the status of associated amphibian populations, has initiated programs in the northeastern United States to document and monitor these habitats. Counting egg masses is an effective way to determine the population size of pool-breeding amphibians, such as wood frogs (Rana sylvatica) and spotted salamanders (Ambystoma maculatum). However, ...
