The Delaware River Basin Collaborative Environmental Monitoring and Research Initiative: Foundation Document United States Department of Agriculture The Delaware River Forest Service Basin Collaborative Northern Research Station Environmental Monitoring General Technical Report NRS-25 and Research Initiative: Foundation Document Edited by: Peter S. Murdoch Jennifer C. Jenkins Richard A. Birdsey Abstract In 1998 the U.S. Forest Service, the U.S. Geological Survey, and the National Park Service formed the Collaborative Environmental Monitoring and Research Initiative (CEMRI) to test strategies for integrated environmental monitoring among the agencies. The initiative combined monitoring and research efforts of the participating Federal programs to evaluate health and sustainability of forest and freshwater aquatic systems in the Delaware River Basin. Forest ecosystem health issues addressed by the CEMRI effort include urbanization and forest fragmentation, productivity and carbon sequestration, nitrogen saturation and calcium depletion, vulnerability to exotic insects, and the effects of interactions among these factors. Ongoing monitoring programs were enhanced with supplemental sampling locations and measurements, and models were developed or modified to associate intensive process-level information with extensive landscape-scale information from satellite, aerial, and ground monitoring systems. The CEMRI project illustrates a powerful approach for integrated tracking of environmental conditions, development of models for predicting responses of forest and aquatic processes to perturbations, estimation of future forest conditions, and identification of threats to watershed health and forest sustainability. This paper discusses the development of the CEMRI in the DRB and methods to address environmental issues across multiple spatial and temporal scales. The Editors PETER S.

  • Assessment of Public Comment on Draft Trout Stream Management Plan
    Assessment of public comments on draft New York State Trout Stream Management Plan OCTOBER 27, 2020 Andrew M. Cuomo, Governor | Basil Seggos, Commissioner A draft of the Fisheries Management Plan for Inland Trout Streams in New York State (Plan) was released for public review on May 26, 2020 with the comment period extending through June 25, 2020. Public comment was solicited through a variety of avenues including: • a posting of the statewide public comment period in the Environmental Notice Bulletin (ENB), • a DEC news release distributed statewide, • an announcement distributed to all e-mail addresses provided by participants at the 2017 and 2019 public meetings on trout stream management described on page 11 of the Plan [353 recipients, 181 unique opens (58%)], and • an announcement distributed to all subscribers to the DEC Delivers Freshwater Fishing and Boating Group [138,122 recipients, 34,944 unique opens (26%)]. A total of 489 public comments were received through e-mail or letters (Appendix A, numbered 1-277 and 300-511). 471 of these comments conveyed specific concerns, recommendations or endorsements; the other 18 comments were general statements or pertained to issues outside the scope of the plan. General themes to recurring comments were identified (22 total themes), and responses to these are included below. These themes only embrace recommendations or comments of concern. Comments that represent favorable and supportive views are not included in this assessment. Duplicate comment source numbers associated with a numbered theme reflect comments on subtopics within the general theme. Theme #1 The statewide catch and release (artificial lures only) season proposed to run from October 16 through March 31 poses a risk to the sustainability of wild trout populations and the quality of the fisheries they support that is either wholly unacceptable or of great concern, particularly in some areas of the state; notably Delaware/Catskill waters.

From this area ferry services Iink Manhattan with New Jersey in minutes, while fleets of excursion craft stand by for sightseeing trips and dinner cruises around the island, or for day-long trips up the Hudson.

The Hollidaysburg and Huntingdon quadrangles are adjoin­ Virginia and Pennsylvania, is over 60 miles wide in North RELIEF ing areas in the south-central part of Pennsylvania, in Blair, Carolina. It is a rugged region of hills and ridges and deep, The lowest point in the quadrangles is at Huntingdon, Bedford, and Huntingdon Counties. (See fig. 1.) Taken as narrow valleys. The altitude of the higher summits in Vir­ where the altitude of the river bed is about 610 feet above sea ginia is 3,000 to 5,700 feet, and in western North Carolina 79 level, and the highest point is the southern extremity of Brush Mount Mitchell, 6,711 feet high, is the highest point east of Mountain, north of Hollidaysburg, which is 2,520 feet above the Mississippi River. Throughout its extent this province sea level. The extreme relief is thus 1,910 feet.
