This dataset is a literature compilation dataset. Plant classification, above-ground biomass, precipitation zoning and ecological habitat information comes from Egyptian documents on desert plant ecology, vegetation science, pasture ecology and arid zone research. During the data collation process, plant species were used as the basic recording unit, and plant scientific names, family names, common names, above-ground biomass range, annual precipitation in the study area, habitat types and reference sources were extracted, and records were divided into semi-arid areas according to annual precipitation. Arid areas, arid areas and extremely arid areas.", "ds_quality": "
The data quality control of this dataset is mainly carried out for literature sources, taxonomic information and data compilation process. During the data collation process, records with clear species names, above-ground biomass or ecological environment information and reference sources are used as data collection objects, and the reference study corresponding to each record is retained to ensure traceability of the data sources. Fields such as plant scientific name, family name, above-ground biomass, precipitation level, habitat description and reference documents are checked one by one to check the consistency of species names and classification information, the standardization of units of measurement, and the logic between precipitation and precipitation zoning.

This dataset compiles classification, above-ground biomass, precipitation zoning and ecological habitat information on deserts and wild plants in Egypt. The existing document contains 100 records covering 31 plant families. Based on annual precipitation, plant records are divided into semi-arid areas, arid areas and extremely arid areas. Among them, the semi-arid areas are 100-200 mm·yr ³, with a total of 25 records; the arid areas are 30-100 mm·yr ³, with a total of 39 records; and the extreme arid areas are less than 30 mm·yr ³, with a total of 36 records. Data fields include plant scientific name, family name, Arabic name or English common name, above-ground biomass range, precipitation zoning, main ecological habitats and adaptive characteristics, and reference sources. The above-ground biomass of plants is mainly expressed in kg·ha ‰, and some woody plants are expressed in t·ha ‰. This dataset can be used to understand the floristic composition, aboveground biomass range and main habitat types in Egypt with different drought levels. However, it should not be directly used for quantitative comprehensive analysis until duplicate species, taxonomic names, units and references have been verified.\r\n
This dataset is currently stored in PDF form and has a total of 7 pages and 100 records. The data covers 31 plant families, including Legumentum, Amaranaceae, Compositae, Gramineae, Labiatae, Tribulaceae, Oleaniaceae, etc. Each record includes serial number, plant scientific name, family name, Arabic name or English common name, above-ground biomass range, annual precipitation zoning, ecological habitat and main characteristics, and reference sources.\r\n
The above-ground biomass data is expressed in range format, with 85 records using kg·ha ‰ and 15 records using t·ha ‰. Precipitation zones include semi-arid areas (100-200 mm·yr 丨), arid areas (30-100 mm·yr 丨) and extremely arid areas (<30 mm·yr 丨).

Extract plant scientific names, family names, common names, above-ground biomass, habitat and precipitation information from relevant documents and organize them according to unified fields. Plant scientific and family names are verified according to the unified plant classification list, and duplicate species are merged or retained as independent observation records based on their original sources.
