WETLAND CREA-nON/RESTORA'nON • lack of adequate maintenance, monitoring, and management activities after the completion of the initial construction • poor planning or design • inexperienced or untrained workers • invasion of undesirable vegetation • poor understanding of the replaced wetland or general wetland system parameters • lack of adequate funding • the failure to establish proper hydrologic conditions • lack of application of criteria for success. If these problems are addressed, the probability of suc- cess may be increased. All of the aforementioned issues indicate a need for more information and easier access to existing infor- mation. The WCR data base serves as a guide to wetland restoration and creation information, includ- ing identification of researchers, project locations, techniques that have been used, project costs, and project evaluation. The purpose of the data base is to enable users to benefit from the experiences and re- search of others and to facilitate the distribution of pertinent information, thereby increasing the chances for project success. Report Contents (selected key words or key word combinations repre- senting a variety of creation and restoration subjects), and (4) Wetland Type. Examples of index use are provided. The data base records are intended for cross- referencing with the indexes. The records are ar- ranged in alphabetical order by author and in numer- ical order by item number. Each data base record here is based on seven selected fields from each entry in the computer data base: author, year, title, source, re- sponse, plant genera, and annotation. The data base records in Appendix C differ slightly from the com- puter entries. Some fields are concentrated and minor editorial changes have been made for this publication. Description of Fields and Summary of Record Information The following descriptions correspond to the infor- mation contained in each complete record of the WCR data base. The fields included in the data base records in this report are denoted by an asterisk (*). Author The author's name is entered last name first, followed by initials. This report describes the information contained in the WCR data base in three main sections: (1) De- scription of Fields and Summary of Record Informa- tion, (2) Indexes, and (3) Data Base Records. The description of fields defines and describes all fields and key words contained in the data base re- cords. Each record represents a discrete literature reference or article possessing a unique item number. This section alerts the reader to subtleties that might not otherwise be apparant in the use and meaning of key words and fields. Understanding of all key words and fields as they are used in the WCR data base is essential for the most effective use of the other sections of this report. Record information is briefly summa- rized by field in graphs and tables. These summaries provide the reader with an idea of what information may be found in the data base on a particular subject. The indexes consist of selected key words and sub- ject combinations, and they list item numbers for those records containing the information specified. Thus, the indexes are used to locate individual data base records that contain specific types of information. There are four indexes: (1) Plant Genus (the 120 plant genera most frequently discussed in the data base records), (2) Location (the locations of wetland cre- ation and restoration projects or studies), (3) Subject Year This is the year of publication of the article. Articles are reported from 1940-88. Although the data base is not all-inclusive, it is clear that work in the field of wetland restoration and creation began to increase sub- stantially in the mid-1970's (Fig. 2). Title This is the complete title of the article or report. Source Source is the bibliographic citation. State This field denotes the location by State(s) or foreign country of the wetland(s) discussed in the reference. State names are abbreviated according to U.S. postal code. For articles discussing wetlands located in 1-10 different States, the States are listed individually, more than 10 States are recorded as "many." The number of times a particular State appears in the data base as a location is shown in Table 1. Many records contain multiple location entries. For articles pertaining to wetlands outside the United States, this field contains the name of the country where the study was conducted.
