Abstract：
The author team established five fixed sample plots within the Baisha Lake area of Poyang Lake Nanjishan Reserve in 2017, where it was a beach environment with minimal human disturbance, frequent activities of herbivorous waterbirds, dense bird droppings, and well-developed vegetation. An in-situ decomposition simulation experiment was conducted using Carex cinerascens Kükenth litter and droppings additions from herbivorous overwintering waterbirds (primarily Anatidae). Samples were collected on the 5th, 15th, 30th, 60th, 90th, 120th, and 150th days after deployment to systematically obtain dynamic data on the organic matter decomposition process and the cycling of carbon, nitrogen, and phosphorus elements, forming the Dataset of Poyang Lake Herbivorous Wintering Waterbird droppings and Carex cinerascens Kükenth Decomposition. The data results indicate that the addition of bird feces significantly accelerated the decomposition rate of Carex cinerascens Kükenth litter. Although bird droppings decomposed relatively slowly, they exhibited high nitrogen and phosphorus release capacity. The dataset includes: (1) geo-location information of the sample plots; (2) dry matter decomposition rate of samples; (3) lignin decomposition data; (4) cellulose decomposition data; (5) total carbon return; (6) total nitrogen return; and (7) total phosphorus return. The dataset is archived in .shp and .xlsx formats, and consists of 9 files with data size of 96.4 KB (Compressed into one file with 89.3 KB).
