"National List of Vascular Plant Species That Occur in Wetlands: 1996 National Summary."
Intro 1996 National List of Vascular Plant Species That Occur in Wetlands The Fish and Wildlife Service has prepared a National List of Vascular Plant Species That Occur in Wetlands: 1996 National Summary (1996 National List). The 1996 National List is a draft revision of the National List of Plant Species That Occur in Wetlands: 1988 National Summary (Reed 1988) (1988 National List). The 1996 National List is provided to encourage additional public review and comments on the draft regional wetland indicator assignments. The 1996 National List reflects a significant amount of new information that has become available since 1988 on the wetland affinity of vascular plants. This new information has resulted from the extensive use of the 1988 National List in the field by individuals involved in wetland and other resource inventories, wetland identification and delineation, and wetland research. Interim Regional Interagency Review Panel (Regional Panel) changes in indicator status as well as additions and deletions to the 1988 National List were documented in Regional supplements. The National List was originally developed as an appendix to the Classification of Wetlands and Deepwater Habitats of the United States (Cowardin et al.1979) to aid in the consistent application of this classification system for wetlands in the field.. The 1996 National List also was developed to aid in determining the presence of hydrophytic vegetation in the Clean Water Act Section 404 wetland regulatory program and in the implementation of the swampbuster provisions of the Food Security Act. While not required by law or regulation, the Fish and Wildlife Service is making the 1996 National List available for review and comment. -
Conservation Plant Release Brochure for Catskill Dwarf Sand Cherry
A Conservation Plant Released by the Natural Resources Conservation Service Big Flats Plant Materials Center, Big Flats, New York Conservation Uses ‘Catskill’ Catskill is mainly used in shoreline and streambank stabilization practices and riparian buffer plantings, where Dwarf Sand Cherry low vegetation is preferred. Its growth habit makes it adapted to areas with ice floe problems. Prunus pumila var. depressa L. Due to its prostrate growth, it may become shaded out over time by taller vegetation. The fruits produced by Catskill are valuable for wildlife and is a very attractive plant and is used in ornamental landscaping. Area of Adaptation and Use Catskill grows well on gravelly or sandy soils along streams but has performed well on silt loam and calcareous soils. It will tolerate periodic flooding only for a short period. Its massive root system allows it to tolerate drought conditions. It is found from Ontario, Canada to the New York- Pennsylvania border and is adapted to USDA hardiness zones 3b to 6b. ‘Catskill' dwarf sand cherry planted among rip rap, in New York. ‘Catskill’ dwarf sand cherry (Prunus pumila var. depressa Establishment and Management for Conservation (L.)) was released in 1997, by the USDA Natural Plantings Resources Conservation Service (NRCS), Big Flats Plant Establishment: Planting 1-0 nursery bare root stock of Materials Center and the Pennsylvania Game Commission Catskill is the preferred method of establishment. for its prostrate growth habit and immense root system.

Note pitch pine in right foreground and little bluestem in opening. NRCS Natural Resources Conservation Service (603) 868-7581 - www.nh.nrcs.usda.gov Ammann, A. P. - DRAFT 03/31/00 1 PURPOSE OF THIS DOCUMENT The purpose of this document is to provide guidance for planning ecosystem management and restoration projects in saline tidal wetlands in New Hampshire. It is intended for professional environmental planners including NRCS field office personnel. It may also be useful as an educational tool for interested laypersons including members of town Conservation Commissions. Non professional uses of this document are cautioned that ecosystem restoration requires professional judgement based on education and experience. GEOGRAPHIC AREA TO WHICH THIS DOCUMENT APPLIES This document is intended for New Hampshire. Knowledgeable persons can apply it to New England. Many of the principles and structure of this document can be adapted to other areas of the United States ECOSYSTEM DESCRIPTION Drylands are those portions of the New Hampshire landscape that typically have low available soil moisture due to their coarse textures soils and position in the landscape. Under natural conditions fire dependent sub-climax communities (Pine Barrens and native grasslands) occur as a patchwork within a matrix of white pine (Pinus strobus L.) and mixed hardwood dry forest matrix. The sub-climax communities arise in the open sunny conditions following fire and are dominated by pitch pine (Pinus rigida Miller), red pine (Pinus resinosa Aiton) and to the north by jack pine (Pinus banksiana Lambert). -
