MARQUALPIE LAND SYSTEM Survey, Biological Survey of South Australia - Vegetation Survey, Biological Database of South Australia

Part of the ongoing Biological Survey of South Australia. To sample the range of vegetation communities and landform types occurring in the region (Outback). The survey conducted in 2008/2009 surveyed the variety of habitats present in the Marqualpie Land System, and the fauna within them. Marqualpie Land System. Jumbled sand dunes and sand plains. Jumbled dunes, sandplains, channels and swampy flats abutting tableland country on Cordillo Downs and Innamincka Regional Reserve. Red dunes with sandhill wattle, sandhill spider flower and rattlepods over dense spinifex; a variety of flats with lignum, canegrass, Queensland bluebush, neverfail, Mitchell grass and coolibah on the channels and deeper depressions; sandplains with mulga, dead finish and bloodwood over woolybutt, spinifex and annual grasses. The MARQUALPIE LAND SYSTEM Survey is part of the Biological Survey of South Australia Program which is a series of systematic surveys conducted across the state between 1971 and the present with the broad aim of providing a baseline inventory of South Australia's flora and fauna biodiversity.

本数据集为南澳大利亚州持续开展的生物调查项目的组成部分，旨在全面采样该内陆腹地（Outback）区域内分布的各类植被群落与地貌类型。本次2008/2009年度的调查，针对马尔夸皮土地系统（Marqualpie Land System）内的各类生境及其内部的动物群落展开了系统普查。

马尔夸皮土地系统以混杂沙丘与砂质平原为核心地貌特征，区域内分布交错的沙丘、砂质平原、河道与沼泽平地，毗邻科迪洛当斯（Cordillo Downs）及伊纳明卡区域保护区（Innamincka Regional Reserve）的台地地带。具体生境的植被组成如下：红色沙丘上生长着沙山金合欢（sandhill wattle）、沙山蜘蛛花（sandhill spider flower）与猪屎豆属植物（rattlepods），下层覆盖茂密的旋刺草（spinifex）；各类平地的河道与深层洼地分布着具节灌木（lignum）、 cane草（canegrass）、昆士兰蓝灌木（Queensland bluebush）、永不旱草（neverfail）、米切尔禾草（Mitchell grass）与库利巴桉（coolibah）；砂质平原则生长着穆尔加金合欢（mulga）、枯梢金合欢（dead finish）与血皮木（bloodwood），下层伴生毛桉（woolybutt）、旋刺草（spinifex）与一年生禾草。

马尔夸皮土地系统调查是南澳大利亚州生物调查计划（Biological Survey of South Australia Program）的组成部分，该计划自1971年起在全州范围内开展系列系统性调查，其核心目标为建立南澳大利亚州动植物生物多样性的基线名录。请通过以下链接获取本数据集：http://aekos.org.au/collection/sa.gov.au/bdbsa_veg/survey_612
