Litter fall data from mangroves in estuaries in northern Queensland

Litter fall data were collected from the estuaries of the Daintree River, Barron River, Crystal Creek and two sites in the Mackay area (McCready's Creek and Mount Bassett).Six litter catchers were deployed in each estuary except for Mackay, where 3 catchers were deployed at each site. Litter catchers were emptied monthly for a period of a year. Litter was identified to species where possible and for each taxa, the weight of leaves, stipules, wood, debris, buds, flowers, immature fruit and mature fruit was recorded. For the mangrove species Xylocarpus granatum and Xylocarpus mekongensis, the number of leaves, stipules, buds, flowers, immature fruit and mature fruit were also counted. This research was undertaken to examine seasonal litter fall in mangrove forests in northern Queensland.

本研究的凋落物数据采集于丹特里河（Daintree River）、巴伦河（Barron River）、克里斯特尔溪（Crystal Creek）的河口，以及麦凯地区（Mackay area）的2个样点：麦克雷迪溪（McCready's Creek）与巴塞特山（Mount Bassett）。除麦凯地区外，每个河口均布设6台凋落物收集器；麦凯地区的每个样点则布设3台凋落物收集器。凋落物收集器每月清理一次，持续周期为1年。对采集到的凋落物尽可能鉴定至物种水平，并针对每个分类类群，记录其叶片、托叶、木质残体、碎屑、芽、花、未成熟果实与成熟果实的重量。针对红树物种木果楝（Xylocarpus granatum）与湄公河木果楝（Xylocarpus mekongensis），还统计了其叶片、托叶、芽、花、未成熟果实与成熟果实的数量。本研究旨在探究昆士兰州北部红树林的季节性凋落物动态。
