Northern Murray Mallee Landscape Restoration Trial Survey

Northern Murray Mallee Landscape Restoration Process Trial. Part of a larger project to trial a process (Willoughby 2006) where information and planning at relevant scales will be used to suggest appropriate on-ground works. Approximately 165-200 sites will be surveyed.
Survey Area, 3 trial landscapes- initially suggested as:
- Billiatt/Wanbi - variegated;
- Mantung/Maggea - fragmented; and
- Paruna/Pata - relictual.
These landscapes include the range of landscape categories (McIntyre and Hobbs,2000):
- Intact - < 10 % destroyed and/or low levels of modification;
- Variegated - 10-40 % destroyed and/or low-high modification;
- Fragmented - 40-90 % destroyed and/or low-high levels of modification
- Relictual - > 90 % destroyed and/or mostly highly modified.

Site Selection: Sites will be stratified against variables (native veg cover and type (floristics), landscape, soils) that may be used to model biota distn and predictive habitat modelling.

Birds: At least 500 bird counts per 2 ha/20 min/site and 3 counts/site for estimates of detectability.

Plants: Biological Survey of SA standard. Some Murray Mallee (BS16) sites to be revisited. This offers an opportunity toward establishing trends in condition. Also, as site condition information will be collected in conjunction with vegetation information at each site.

Site condition: Landscape function analysis (LFA) will be assessed for all sites (Tongway and Hindley 2004).

Survey started in 2005, and is still going. The Northern Murray Mallee Landscape Restoration Trial 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.

北墨累马尔基（Northern Murray Mallee）景观恢复流程试验。本试验隶属于一项更大规模的流程试验项目（Willoughby, 2006），该项目将通过匹配相关尺度的信息与规划，为实地作业提供适宜建议，计划完成约165至200个样地的调查工作。

调查区域包含3个试验景观，初步拟定为：
- 比利亚特/万比（Billiatt/Wanbi）——斑驳型（variegated）；
- 曼通/马吉亚（Mantung/Maggea）——破碎型（fragmented）；
- 帕鲁纳/帕塔（Paruna/Pata）——遗痕型（relictual）。

上述景观涵盖了麦金泰尔与霍布斯（McIntyre & Hobbs, 2000）提出的全部景观分类类型：
- 完整型（Intact）：受破坏比例<10%，且改造程度较低；
- 斑驳型（Variegated）：受破坏比例为10%-40%，改造程度从中低至高不等；
- 破碎型（Fragmented）：受破坏比例为40%-90%，改造程度从中低至高不等；
- 遗痕型（Relictual）：受破坏比例>90%，且改造程度普遍较高。

样地选择：将依据用于构建生物群落分布模型与预测性生境模型的变量对样地进行分层抽样，变量包括本土植被覆盖度与类型（植物区系floristics）、景观类型、土壤类型。

鸟类调查：每个2公顷样地需完成至少500次鸟类计数（单次时长20分钟），且每个样地需开展3次计数以估算检测概率（detectability）。

植物调查：遵循南澳大利亚生物调查（Biological Survey of SA）标准。部分墨累马尔基（Murray Mallee）样地（编号BS16）将进行重访，此举可为建立样地状况变化趋势提供契机。同时，每个样地将同步收集植被信息与样地状况相关数据。

样地状况：将针对所有样地开展景观功能分析（Landscape Function Analysis, LFA）（Tongway & Hindley, 2004）。

本次调查始于2005年，目前仍在进行中。北墨累马尔基景观恢复试验调查隶属于南澳大利亚生物调查计划（Biological Survey of South Australia Program），该计划自1971年起至今，在全州范围内开展了一系列系统性调查，核心目标是为南澳大利亚的动植物生物多样性建立基线名录。
