  • 2.1 Regional Setting the Upper Schoharie Creek Watershed Is
    2.1 Regional Setting The Upper Schoharie Creek watershed is located in the southeastern region of NY State (Fig 2.1.1). Approximately 80% of the 93 mi2 main stem watershed lies within the towns of Hunter, Jewett, Lexington, and Prattsville. The remainder of the watershed lies within Gilboa and Roxbury, with small pieces in Ashland and Conesville. The entire watershed basin is 316 mi2 and receives waters from other creeks such as the Batavia Kill, West Kill and East Kill. The entire watershed basin also includes Windham and small parts of Jefferson, Stamford, and Halcot (Fig 2.1.2). Approximately 75% of the Schoharie Creek watershed is located within the Catskill Park. Figure 2.1.1 Schoharie Creek watershed counties In 1885, the Catskill and Adirondack Forest Preserves were established by the NY State Assembly. An 1894 amendment to the New York State Constitution (now Article 14) directs “the lands of the State now owned or hereafter acquired, constituting the forest preserve as now fixed by law, shall be forever kept as wild forest lands. They shall not be leased, sold or exchanged, or be taken by any corporation, public or private, nor shall the timber thereon be sold, removed or destroyed” (NYS DEC, 2006). In 1904, the Catskill Park was designated, establishing a boundary or ‘blue line’ around the Forest Preserve and private land as well. Over the years the Catskill Park grew, and now comprises roughly 700,000 acres, about half of which is public Forest Preserve. The Catskill and Adirondack Parks are nationally unique because they are a checkerboard of public and private land; a grand experiment in how nature and human society can State Land historical marker Schoharie Creek Management Plan 2.1.1 coexist in a landscape (Catskill Center1, 2006).

Lammers ABSTRACT. Morphological and phytogeographical data support the recognition of three distinct species in the genus Bmch/eïytrum: B. japonicum, B. ereclum, and B. aristosum. Bmchyelytrum japonicum is confined to eastern Asia and is charac- terized by narrow leaf blades (0.5-0.8 cm wide), long lower glumes {0.2-2.0 mm long), and long rachiUas (6.8-8.8 mm long). Bmchyelytrum ¿rectum is distributed throughout much of the eastern United States, from northwestern Minnesota south to central Louisiana, east to northern Florida and north to northeastern New York. Brachyelytrum erectum is characterized by long hispid hairs (0.2-0.9 mm long) on the veins of the lemma, wide lemmas (0.8-1.8 mm wide), and a conspicuous lemma mid-vein. Brachyelytrum aristosum has a more northern distribution, occurring in southern Canada from southern Ontario to Newfoundland, the northern adjacent United States and through the Appalachian mountains to northwestern North Carolina. Brachyelytrum aristosum is characterized by short scaberulous hairs (0.06-0.2 mm long) on the lemma and narrow lemmas (0.7-1.4 mm wide) that are weakly veined.

(paper cover) FOEEWOBD The "Lexicon of geologic names of the United States" by M. Grace Wilmarth, published in 1938 and reprinted in 1951 and 1957, met a long standing need and continuing demand for a compilation of geologic names. Plans made for future compilations as new names and revisions appeared were interrupted during the years of World War II. In 1952 a sustained effort was begun toward review of geo­ logic publications necessary to furnish a background for preparation of a new edition. After the review was brought up to date in 1956, the present compilation was prepared in order to furnish to the geo­ logic profession, as quickly as possible, some of the essential data concerning the new names that have appeared since 1935.

  • Third Infantry Division Highway Corridor Study
    THIRD INFANTRY DIVISION HIGHWAY CORRIDOR STUDY Task 7 Study Alignments and Design Levels Draft Technical Memorandum 1. Executive Summary Section 1927 of the Safe, Accountable, Flexible, Efficient Transportation Equity Act: A Legacy for Users (SAFETEA‐LU) (P.L. 109‐59) requires “a report that describes the steps and estimated funding necessary to designate and construct a route for the 3rd Infantry Division Highway,” extending from Savannah, Georgia to Knoxville, Tennessee, byy wa of Augusta, Georgia. The intent of this study is to develop planning level cost estimates for potential corridors connecting these urban areas. This information will be presented to Congress to fulfill the statutory language and present an overview of the steps necessary to construct such a corridor. The study is not intended to select an alternative for implementation; it will not necessarily lead to any further planning, design, right‐of‐way acquisition, or construction activities for any specific highway improvement. This technical memorandum recommends initial study corridors and design levels for the 3rd Infantry Division Highway corridors along with supporting justification and the rationale for the recommendations. Input from the Expert Working Group (EWG) was considered during the development of the Alignments and Design Levels. The EWG is a panel of area transportation officials and federal resource agencies that helps guide the project. The EWG serves as a sounding board to weigh technical options, examine issues from multiple perspectives and, by drawing upon its collective experience, help the team solve problems. Tasks 8‐9 in the study involve examining any corridors recommended for additional study in greater detail.
