The many individual salamanders, frogs, caecilians, and their larvae encountered during the course of an inventory or monitoring project will have to be identified to species. Depending on the goals and sampling method(s) used, some individuals will be identified from a distance by their calls, others will be handled. At the same time, some will be marked for recapture, and others will be sampled as vouchers. For each, certain minimum data should be recorded. In this section, data pertaining to locality and sampling methodology are considered, information on microhabitats and specimen vouchers is covered in sections that follow. I feel strongly that the data outlined here should be the minimum for any project. Investigators with specific goals may require additional types of data as well.
Standardized, printed sheets containing the required data categories provide a convenient, inexpensive, and effective way to ensure that all the desired information is recorded in a consistent format, Data sheets should be well organized, printed on good-quality paper (75%-100% cotton content) and include extra space (e.g., other side of sheet) for notes that do not fit preestablished categories
Data should be recorded in the field with permanent (waterproof) ink as simply and directly as possible. I strongly recommend against the use of data codes in the field; it is too easy to forget codes or to enter the wrong code. Original data sheets can be photocopied for security, but they should not be copied by hand. If data are to be coded for computer analysis, the original or photocopied sheets should be used for data entry to minimize transcription errors. Some workers prefer recording information on small tape recorders; this also works well if a list of the standard data categories is checked during taping to ensure that all required information is recorded. Information recorded on tapes should be transcribed to data sheets or into a computer within 24 hours of the sample.

Species are grouped into 3 systems of guild classifications representing migration status, breeding habitat and nesting substrate. Trends for these groups are summarized by time period, bioregion and physiographic region. At the continental level, declines approximately equalled increases. There are slightly more declines during the last 10 years. Prairie populations declined more than expected, while western populations increased. Scrub and grassland nesting species declined significantly in several bioregions while woodland species increased. Most guilds did not depart significantly from a ratio of 50:50 increases to decreases or have opposing trends in different bioregions. Guild group changes are usually clustered geographically. Guild and other analyses that search for patterns among population trend estimates offer an excellent means of identifying critical conservation issues.","largerWorkType":{"id":4,"text":"Book"},"largerWorkTitle":"Bird Numbers 1992: Distribution, monitoring and ecological aspects","largerWorkSubtype":{"id":4,"text":"Other Government Series"},"language":"English","publisher":"Statistics Netherlands and SOVON","publisherLocation":"Voorburg/Heerlen and Beek-Ubbergen, Netherlands","collaboration":"Proceedings of the 12th International Conference of the International Bird Census Committee (IBCC) and the European Ornithological Atlas Committee (EOAC) held September 14-18, 1992, Noordwijkerhout, Netherlands.
